-**Why a set coding style is important** <br>
-This project is an open source project. To get open source working as intended, many people should be able to comprehend the code. This implies that there is a well documented and uniform flow of code.
-That does not necessarily mean that a contributor should not write optimised yet cryptic code - one should always care about performance.  However, other developers need to understand the code which means complicated parts of code **must** have good documentation.
-
-**Why we require that EVERYTHING is documented**<br>
-What is simple to some might appear very complicated to others. Documentation helps these others. Anyone should be able to improve the code. But the main reason is, that when patch contributors want their patches added to the common codebase, the code needs to be reviewed by one or more developers. Documentation makes reviewing much easier.
-
-## Coding style for OpenTTD
-### Functions
-* Function names use [CamelCase](http://www.wikipedia.org/wiki/Camelcase) without underscores.
-* Opening curly bracket **{** for a function starts on the next line.
-* Use Foo() instead of Foo(void).
-* Prefer using "const" for reference and compound parameters when appropriate.
-* If a member function can be a const function, make it so.
-```c++
-void ThisIsAFunction()
-{
-}
-```
-
-### Variables
-* Variable names are all lowercase, and use "_" as separator.
-* Global variables are preceded by an underscore. ("_") Use descriptive names because leading underscores are often used for system / compiler variables.
-* Own members of classes should always be referenced using "this->"
-* Pointers and references should have their reference symbol next to the name (compatibility with current code).
-* Variables that are declared below one another should have their type, name or reference operator, and assignment operator aligned by spaces.
-* There are set names for many variables. Those are (but not limited to): Vehicle *u, *v, *w; Station *st; Town *t; Window *w; Engine *e.
-* For multiple instances, use numbers "*t1, *t2" or postfixes "*st_from, *st_to".
-* Declare variables upon first usage.
-* Declare iterators in their loop.
-* There is a space between '*' and 'const' in "const pointers"
-```c++
-int     number         = 10;
-Vehicle *u_first_wagon = v->next;
-int     value          = v->value;
-
-uint32 _global_variable = 3750;
-
-static const char * const _global_array[] = {
-	"first string",
-	"second string",
-	"another string",
-	"last string followed by comma",
-};
-
-protected:
-	char protected_array[10];
-
-for (int i = 0;;);
-```
-
-* Give the variables expedient names, this increases the readability of the code
-```c++
-bool is_maglev_train = true;
-if (!is_maglev_train) DoSomething();
-```
-
-* Some people like to introduce copies of variables to increase readability, which can waste memory. However, in some cases, especially in code pieces which are often called, it makes sense to cache some calculated variables.
-```c++
-/* Unoptimized code:
- * foo is not touched inside the loop!
- */
-for (uint8 i = 0; i < 100000; i++) {
-	/* Do something */
-	if (value_to_check == (foo * 4) % 5 + 6) DoSomething();
-	/* Do something else */
-}
-
-/* Better:
- * The used value of foo is calculated outside the loop.
- */
-const uint32 bar = (foo * 4) % 5 + 6;
-for (uint8 i = 0; i < 100000; i++) {
-	/* Do something */
-	if (value_to_check == bar) DoSomething();
-	/* Do something else */
-}
-```
-
-### Enumerations / static consts
-* Enumerations store integers that belong logically together (railtypes, string IDs, etc.).
-* Enumeration names also use CamelCase.
-* Unscoped enumerators are all caps with "_" between the words.
-* Scoped enumerators are use CamelCase.
-* Enums are not used to store single numbers.
-* Enums have consecutive numbers OR
-* Enums have consecutive powers of two. Powers of two (bits) are written in hex or with the shift operator.
-* Enums may have special enumerators: "_BEGIN", "\_END", and "INVALID\_").  See example.
-* The invalid always has 0xFF, 0xFFFF, 0xFFFFFFFF as a value.
-* Other special values are consecutively less than the invalid.
-* Variables that hold enumerators should have the type of the enumeration.
-```c++
-enum DiagDirection {
-	DIAGDIR_BEGIN = 0,
-	DIAGDIR_NE  = 0,
-	DIAGDIR_SE  = 1,
-	DIAGDIR_SW  = 2,
-	DIAGDIR_NW  = 3,
-	DIAGDIR_END,
-	INVALID_DIAGDIR = 0xFF,
-	BROKEN_DIAGDIR = 0xFE,
-};
-
-enum {
-	DEPOT_SERVICE       = (1 << 0),
-	DEPOT_MASS_SEND     = (1 << 1),
-	DEPOT_DONT_CANCEL   = (1 << 2),
-	DEPOT_LOCATE_HANGAR = (1 << 3),
-};
-
-DiagDirection enterdir = DIAGDIR_NE;
-```
-
-* Numbers that store single or uncorrelated data are static consts. Those may use the naming conventions of enums.
-Example:
-```c++
-static const int MAXIMUM_STATIONS = 42;
-```
-
-* Enums are useful in GUI code: When widgets are enumerated, they are easier to access during many operations. Additionally changes caused by modified widget sequences require less code adapting. If a widget is used like this, its enum name should be present in a comment behind the corresponding widget definition.
-```c++
-/** Enum referring to the widgets of the build rail depot window */
-enum BuildRailDepotWidgets {
-	BRDW_CLOSEBOX = 0,
-	BRDW_CAPTION,
-	BRDW_BACKGROUND,
-	BRDW_DEPOT_NE,
-	BRDW_DEPOT_SE,
-	BRDW_DEPOT_SW,
-	BRDW_DEPOT_NW,
-};
-/* ... */
-/** Widget definition of the build rail depot window */
-static const Widget _build_depot_widgets[] = {
-{   WWT_CLOSEBOX,   RESIZE_NONE,     7,     0,    10,     0,    13, STR_00C5, STR_..},   // BRDW_CLOSEBOX
-{    WWT_CAPTION,   RESIZE_NONE,     7,    11,   139,     0,    13, STR_...,  STR_...},  // BRDW_CAPTION
-{      WWT_PANEL,   RESIZE_NONE,     7,     0,   139,    14,   121, 0x0,      STR_NULL}, // BRDW_BACKGROUND
-{      WWT_PANEL,   RESIZE_NONE,    14,    71,   136,    17,    66, 0x0,      STR_..},   // BRDW_DEPOT_NE
-{      WWT_PANEL,   RESIZE_NONE,    14,    71,   136,    69,   118, 0x0,      STR_..},   // BRDW_DEPOT_SE
-{      WWT_PANEL,   RESIZE_NONE,    14,     3,    68,    69,   118, 0x0,      STR_..},   // BRDW_DEPOT_SW
-{      WWT_PANEL,   RESIZE_NONE,    14,     3,    68,    17,    66, 0x0,      STR_..},   // BRDW_DEPOT_NW
-{   WIDGETS_END},
-};
-```
-
-* Comments on the enum values should start with "///<" to enable doxygen documentation
-```c++
-enum SomeEnumeration {
-	SE_BEGIN = 0,        ///< Begin of the enumeration, used for iterations
-	SE_FOO = 0,          ///< Used for xy
-	SE_BAR,              ///< Another value of the enumeration
-	SE_SUB,              ///< Special case for z
-	SE_END,              ///< End of the enumeration, used for iterations
-};
-```
-
-### Control flow
-* Put a space before the parentheses in **if**, **switch**, **for** and **while** statements.
-* Use curly braces and put the contained statements on their own lines (e.g., don't put them directly after the **if**).
-* Opening curly bracket **{** stays on the first line, closing curly bracket **}** gets a line to itself (except for the **}** preceding an **else**, which should be on the same line as the **else**).
-* When only a single statement is contained, the brackets can be omitted. In this case, put the single statement on the same line as the preceding keyword (**if**, **while**, etc.). Note that this is only allowed for if statements without an **else** clause.
-* Non-trivial fall throughs must be documented, using a `[[fallthrough]]` attribute.
-* The NOT_REACHED() macro can be used in default constructs that should never be reached.
-* Unconditional loops are written with **`for (;;) {`**
-
-```c++
-if (a == b) {
-	Foo();
-} else {
-	Bar();
-}
-
-if (very_large_checks &&
-		spread_over_two_lines) {
-	Foo();
-}
-
-if (a == b) Foo();
-
-switch (a) {
-	case 0: DoSomethingShort(); break;
-
-	case 1:
-		DoSomething();
-		[[fallthrough]];
-
-	case 2:
-		DoMore();
-		b = a;
-		break;
-
-	case 3: {
-		int r = 2;
-
-		DoEvenMore(a);
-		[[fallthrough]];
-	}
-
-	case 4: {
-		int q = 345;
-
-		DoIt();
-		break;
-	}
-
-	default:
-		NOT_REACHED();
-}
-
-for (int i = 0; i < 10; i++) {
-	Foo();
-	Bar();
-}
-```
-
-### Classes
-* Classes names also use CamelCase.
-* Classes should have "public", "protected", and "private" sections.
-* Within these section the order is: types, static const members, static members, members, constructors / destructors, static methods, methods.
-* Deviations from above order are allowed when the code dictates it (e.g. a static const is needed for a typedef)
-* Methods and members ought to be grouped logically.
-* All those sorting rules sometimes conflict which one another. Please use common sense what increases legibility of the code in such a case.
-* The method implementation should indicate if it is virtual or similar by using a comment.
-* Very short methods can have one-line definition (if defined in the class scope).
-```c++
-class ThisIsAClass {
-public:
-	typedef Titem_   *ItemPtr;
-private:
-	static const int MAX_SIZE = 500;
-	int              size;
-	ItemPtr          *items;
-
-public:
-	explicit ThisIsAClass();
-	~ThisIsAClass();
-
-	int GetSize() { return this->size; }
-	virtual void Method();
-};
-
-/*virtual*/ void Class::Method()
-{
-	this->size *= 2;
-}
-```
-
-### Templates
-Templates are a very powerful C++ tool, but they can easily confuse beginners. Thus:
-* Templates are to be documented in a very clear and verbose manner. Never assume anything in the documentation.
-* the template keyword and the template layout get a separate line. typenames are either "T" or preceded by a "T", integers get a single capital letter or a descriptive name preceded by "T".
-```c++
-template <typename T, typename Tsomething, int N, uint8_t Tnumber_of_something>
-int Func();
-```
-
-* If you are writing one or more template class in the dedicated header file, use file.hpp for its name instead of file.h. This will let others know that it is template library (includes also implementation), not just header with declarations.
-
-### Code Comment Vertical Alignment
-
-When adding code or comments to an existing formatted section, follow the existing style if possible without editing the preexisting lines.
-
-If your addition cannot be aligned with existing code, do not align the comments with anything and use only a single space between the code and the comment.
-
-Good:
-
-```c++
-enum Vehicle {
-	BUS,  ///< Take the bus.
-+	CAR,  ///< Drive your car.
-	BIKE, ///< Ride your bike
-+	TRAIN, ///< Catch the train.
-}
-```
-
-"Car" is shorter than Bike which allows you to easily align the new comment. "Train" is longer.  It is *NOT* desirable to change the vertical comment alignment of this enum.
-
-Bad:
-
-```c++
-enum Vehicle {
--	BUS,  ///< Take the bus.
--	BIKE, ///< Ride your bike
-+	BUS,   ///< Take the bus.
-+	CAR,   ///< Drive your car.
-+	BIKE,  ///< Ride your bike
-+	TRAIN, ///< Catch the train.
-}
-```
-
-OpenTTD used to vertically-align inline Doxygen comments as shown above. OpenTTD has since stopped strictly following this rule to keep diffs smaller and reduce pollution to the git blame history for non-functional changes.
-
-### Other important rules
-* Put a space before and after binary operators: "a + b", "a == b", "a & b", "a <<= b", etc.. Exceptions are ".", "->" and "[]" (no spaces) and "," (just space after it).
-* Put parenthesis where it improves readability: "*(b++)" instead of "*b++", and "if ((a & b) && c == 2)" instead of "if (a & b && c == 2)".
-* Do not put external declarations in implementation (i.e. cpp) files.
-* Do not typedef enums and structs.
-* Don't treat non-flags as flags: use "if (char_pointer != nullptr && *char_pointer != '\0')", not "if (char_pointer && *char_pointer)".
-* Use "free(p)" instead of "if (p != nullptr) free(p)". "free(nullptr)" doesn't hurt anyone.
-* No trailing whitespace. The Github workflows will not allow tabs or space on the end of lines.
-* Only use tabs to indent from the start of the line.
-* Line length is unlimited. In practice it may be useful to split a long line. When splitting, add two tabs in front of the second part.
-* The '#' of preprocessor instructions goes into the first column of a line. Indenting is done after the '#' (using tabs again).
-* Use /* */ for single line comments.
-* Use // at the end of a command line to indicate comments.
-** However, use /* */ after # preprocessor statements as // causes warnings in some compilers and/or might have unwanted side effects.
-* C++ is defined using the ASCII character set. Do not use other character sets, not even in comments.
-* OpenTTD includes some Objective-C sources (*.mm, used by OSX), which has a special object method invocation syntax: "[ obj doStuff:foo ]". Please use spaces on the inside of the brackets to differentiate from the C array syntax.
-
-## Documentation
-We use [Doxygen](http://doxygen.org/) to automatically generate documentation from the source code. It scans the source files for *recognizable* comments.
-* **Make your comments recognizable.**
-Doxygen only comments starting with the following style:
-```c++
-/**
-///<
-```
-
-Use /** for multi-line comment blocks. Use ///< for single line comments for variables. Use //!< for single-line comments in the NoAI .hpp files.
-For comments blocks inside a function always use /* */ or //. Use // only if the comment is on the same line as an instruction, otherwise use /* */.
-
-### Files
-* Put a @file command in a JavaDoc style comment at the start of the file, followed by a description.
-```c++
-/**
- * @file
- * This is the brief description.
- * This is the detailed description here and on the following lines.
- */
-```
-> ### Warning
-> If a file lacks a **file comment block** then NO entities in that file will be documented by Doxygen!
-
-### Functions
-* The documentation should be as close to the actual code as possible to maximise the chance of staying in sync.
-	* Comments for functions go in the .cpp file.
-	* Comments for inlines go in the .h/.hpp file.
-* Small inlines can have a short 3 or 4 line JavaDoc style comment.
-* Completely document larger functions.
-* Document obvious parameters and return values too!
-
-```c++
-/**
- * A brief explanation of what the function does and/or what purpose it serves.
- * Then follows a more detailed explanation of the function that can span multiple lines.
- *
- * @param foo Explanation of the foo parameter
- * @param bar Explanation of the bar parameter
- * @return The sum of foo and bar (@return can be omitted if the return type is void)
- *
- * @see SomeOtherFunc()
- * @see SOME_ENUM
- *
- * @bug Some bug description
- * @bug Another bug description which continues in the next line
- *           and ends with the following blank line
- *
- * @todo Some to-do entry
- */
-static int FooBar(int foo, int bar)
-{
-	return foo + bar;
-}
-```
-
-### Classes
-* Document structs similarly to functions:
-```c++
-/**
- * A short description of the struct.
- * More detailed description of the its usage.
- *
- * @see [link to anything of interest]
- */
-struct foo {
-}
-```
-
-### JavaDoc structural commands
-
-This table shows the commands you should use with OpenTTD.  The full list is [here](http://www.stack.nl/~dimitri/doxygen/commands.html).
-
-| Command | Action | Example |
-| ------- | -------- | ------- |
-| **@attention** | Starts a paragraph where a message that needs attention may be entered. The paragraph will be indented. | @attention Whales crossing! |
-| **@brief** | Starts a paragraph that serves as a brief description. For classes and files the brief description will be used in lists and at the start of the documentation page. For class and file members, the brief description will be placed at the declaration of the member and prepended to the detailed description. A brief description may span several lines (although it is advised to keep it brief!). | @brief This is the brief description. |
-| **@bug** | Starts a paragraph where one or more bugs may be reported. The paragraph will be indented. Multiple adjacent @bug commands will be joined into a single paragraph. Each bug description will start on a new line. Alternatively, one @bug command may mention several bugs. | @bug Memory leak in here? |
-| **@note** | Starts a paragraph where a note can be entered. The paragraph will be indented. | @note Might be slow |
-| **@todo** | Starts a paragraph where a TODO item is described. The description will also add an item to a separate TODO list. The two instances of the description will be cross-referenced. Each item in the TODO list will be preceded by a header that indicates the origin of the item. | @todo Better error checking |
-| **@warning** | Starts a paragraph where one or more warning messages may be entered. The paragraph will be indented. | @warning Not thread safe! |
-| | <small>**Function related commands**</small> | |
-| **@return** | Starts a return value description for a function. | @return a character pointer |
-| **@param** | Starts a parameter description for a function parameter with name <parameter-name>. Followed by a description of the parameter. The existence of the parameter is checked and a warning is given if the documentation of this (or any other) parameter is missing or not present in the function declaration or definition.<br><br>The @param command has an optional attribute specifying the direction of the attribute. Possible values are "in" and "out". | @param  n    The number of bytes to copy<br>@param[out] dest The memory area to copy to.<br>@param[in]  src  The memory area to copy from. |
-| **@see** | Starts a paragraph where one or more cross-references to classes, functions, methods, variables, files or URL may be specified. Two names joined by either :: or # are understood as referring to a class and one of its members. One of several overloaded methods or constructors may be selected by including a parenthesized list of argument types after the method name. [Here](http://www.stack.nl/~dimitri/doxygen/autolink.html) you can find detailed information about this feature. | @see OtherFunc() |
-| **@b** | Displays the following word using a bold font. Equivalent to &lt;b&gt;word&lt;/b&gt;. To put multiple words in bold use &lt;b&gt;multiple words&lt;/b&gt;.| ...@b this and @b that... |
-| **@c / @p** | Displays the parameter <word> using a typewriter font. You can use this command to refer to member function parameters in the running text. To have multiple words in typewriter font use &lt;tt&gt;multiple words&lt;/tt&gt;. | ... the @p x and @p y coordinates are used to... |
-| **@arg / @li** | This command has one argument that continues until the first blank line or until another @arg / @li is encountered. The command can be used to generate a simple, not nested list of arguments. Each argument should start with an @arg / @li command. | @arg @c AlignLeft left alignment.<br>@arg @c AlignCenter center alignment.<br>@arg @c AlignRight right alignment |
-| **@n** | Forces a new line. Equivalent to and inspired by the printf function. |@n |

-### More on Doxygen and JavaDoc
-
-Doxygen knows two different kinds of comments:
-* *Brief descriptions*: one-liners that describe the function roughly ([example](http://docs.openttd.org/annotated.html))
-* *Detailed descriptions*: as the name suggests, these contain the detailed function/purpose of the entity they describe ([example](http://docs.openttd.org/structBridge.html))
-
-You can omit either one or put them into different places but there's only one brief and one detailed description allowed for the same entity.
-
-Doxygen knows three modes for documenting an entity:
-* Before the entity
-* After the entity
-* In a different file
-
-The latter is a little harder to maintain since the prototype of the entity it describes then is stored in several places (e.g. the .h file and the file with the descriptions). Also while it makes the code easier to read it also makes it easier to omit the important step of updating the description of an entity if it was changed - and we all know why that shouldn't happen ;)<br>
-Because of those reasons, we will only use the first two documentation schemes.
-
-
-Doxygen supports both Qt and JavaDoc comment styles:
-* Qt style example: **int i; //!< The counter for the main loop**
-* JavaDoc style example: **int i; /*\*< The counter for the main loop \*/**
-
-It also supports more comment styles but those two are the ones which are standardized. For OTTD we'll be using the JavaDoc style. One of the reasons is that it has a feature that the Qt style doesn't offer: JavaDoc style comment blocks will automatically start a brief description which ends at the first dot followed by a space or new line. Everything after that will also be part of the detailed description.
-
-The general structure of a JavaDoc style comment is
-```c++
-/**
- * This is the brief description. And this sentence contains some further explanations that will appear in the detailed description only.
- */
-```
-
-and the resulting descriptions of that block would be:
-* *Brief description*: This is the brief description.
-* *Detailed description*: This is the brief description. And this sentence contains some further explanations that will appear in the detailed description only.
-
-The distinction between the brief and detailed descriptions is made by the dot followed by a space/newline, so if you want to use that inside the brief description you need to escape the space/newline:
-```c++
-/**
- * This is a brief description (e.g.\ using only a few words). Details go here.
- */
-```
-
-If you're doing a one-line comment, use:
-```c++
-int i; ///< This is the description.
-```
-
-Also in the comment block you can include so-called structural commands which tell Doxygen what follows. In general, their area of effect begins after the command word and ends when a blank line or some other command is encountered. Also, multiple occurrences of the same structural command within a comment block or the referring entity will be joined in the documentation output usually.
-
-## Commit message
-To achieve a coherent whole and to make changelog writing easier, here are some guidelines for commit messages.
-There is a check-script on the git server (also available for clients, see below) to make sure we all follow those rules.
-
-The first line of a message must match:
-```
-<keyword>( #<issue>|<commit>(, (#<issue>|<commit>))*)?: ([<component>])? <details>
-```
-
-Keywords can either be player-facing, NewGRF / Script author-facing, or developer-facing.
-
-For player-facing changes, we have these keywords:
-* Feature: Adding a significant new functionality to the game. This can be small in code-size, but is meant for the bigger things from a player perspective.
-* Add: Similar to Feature, but for small functionalities.
-* Change: Changing existing behaviour to an extent the player needs to know about it.
-* Fix: Fixing an issue with the game (as seen by the player).
-* Remove: Completely removing a functionality.
-* Revert: Reverting an earlier Feature / Add / Change / Fix / Remove.
-* Doc: Update to (player-facing) documentation, like in the `docs/` folder etc.
-* Update: Translator commits.
-
-For NewGRF / Script author-facing changes, we use the same keywords as player-facing changes, followed by `[NewGRF]` / `[Script]` component.
-This also means the commit is aimed (and worded) towards the NewGRF / Script authors, rather than players.
-
-For developer-facing changes, we have these keywords:
-* Codechange: Changes to the code the player is not going to notice. Refactors, modernization, etc.
-* Cleanup: Similar to Codechange, but when it is more about removing old code, rather than an actual change.
-* Codefix: Fixing problems in earlier commits that the player is not actually going to notice. Wrong comments, missing files, CI changes.
-
-If you commit a `Fix` for an [issue](https://github.com/OpenTTD/OpenTTD/issues), add the corresponding issue number in the form of #NNNNN.
-
-In the case of `Fix`es, if you know the hash of the commit in which the bug was introduced (eg regression), please mention that hash (the first 7 characters) as well just after the keyword (or, if present, after the issue number).
-Finding the trouble-causing commit is highly encouraged as it makes backporting / branching / releases that much easier.
-
-Do not mention two keywords; if two apply, pick one that best represents the commit (for example, "Fix #123" is mostly always better than "Revert", even if both are true).
-
-The `<details>` part starts with a capital and does not end with a dot.
-Try to be descriptive to what the player will notice, not to what is actually being changed in the code.
-See `changelog.md` for inspiration.
-
-To further structure the changelog, you can add components. Example are:
-* "Network" for network specific changes.
-* "NewGRF" for NewGRF additions.
-* "Script" for AI / GS additions.
-* "YAPF", "NPF", for changes in these features.
-* "MacOS", "Linux", "Windows", for OS-specific changes.
-* "CI", "CMake", for changes to the (build) infrastructure.
-
-Further explanations, more details, etc. don't go into the first line. Use a new line for those.
-
-Complete examples:
-* `Fix: [YAPF] Infinite loop in pathfinder`
-* `Fix #5926: [YAPF] Infinite loop in pathfinder`
-* `Codefix 80dffae: Warning about unsigned unary minus`
-* `Fix #6673, 99bb3a9: Store the map variety setting in the savegame`
-* `Codefix #5922: ClientSizeChanged is only called via WndProcGdi which already has the mutex`
-* `Codechange #1264, #2037, #2038, #2110: Rewrite the autoreplace kernel`
-
-
-## Other tips
-### Remove trailing whitespace
-To find out if/where you have trailing whitespace, you can use the following (unix/bash) command:
-```
-grep -n -R --include "*.[ch]" '[ 	]$' * | grep --invert-match ".diff" | grep --invert-match ".patch"
-```
-Automatically removing whitespace is also possible with the following shell script (Note that it only checks .c, .cpp, .h, .hpp and .mm files):
-```
-#!/bin/sh
-IFS='
-'
-for i in Makefile `find . -name \*.c -o -name \*.cpp -o -name \*.h -o -name \*.hpp -o -name \*.mm`
-do
-  (
-	echo '%s/[ 	]\{1,\}$/'
-	echo w
-	echo q
-  ) | ed $i 2> /dev/null > /dev/null
-done
-```
-
-### Install the client-side git commit hooks
-
-The client-side hooks perform various checks when you commit changes locally.
-* Whitespace and indentation checks.
-* **Coding style** checks.
-
-Get the hooks:
-```
-git clone https://github.com/OpenTTD/OpenTTD-git-hooks.git openttd_hooks
-```
-
-Install the hooks, assuming "openttd" is your work tree folder:
-```
-cd openttd/.git/hooks
-ln -s -t . ../../../openttd_hooks/hooks/*
-```

-# Compiling OpenTTD
-
-## Required/optional libraries
-
-OpenTTD makes use of the following external libraries:
-
-- (encouraged) breakpad: creates minidumps on crash
-- (encouraged) zlib: (de)compressing of old (0.3.0-1.0.5) savegames, content downloads,
-   heightmaps
-- (encouraged) liblzma: (de)compressing of savegames (1.1.0 and later)
-- (encouraged) libpng: making screenshots and loading heightmaps
-- (optional) liblzo2: (de)compressing of old (pre 0.3.0) savegames
-
-For Linux, the following additional libraries are used:
-
-- (encouraged) libcurl: content downloads
-- libSDL2: hardware access (video, sound, mouse)
-- libfreetype: loading generic fonts and rendering them
-- libfontconfig: searching for fonts, resolving font names to actual fonts
-- harfbuzz: handling of right-to-left scripts (e.g. Arabic and Persian) (required libicu)
-- libicu: handling of right-to-left scripts (e.g. Arabic and Persian) and
-   natural sorting of strings
-
-If you are building a dedicated-server only, you don't need the last four.
-
-OpenTTD does not require any of the libraries to be present, but without
-liblzma you cannot open most recent savegames and without zlib you cannot
-open most older savegames or use the content downloading system.
-
-## Windows
-
-You need Microsoft Visual Studio 2022 or more recent.
-
-You can download the free Visual Studio Community Edition from Microsoft at
-https://visualstudio.microsoft.com/vs/community/.
-
-OpenTTD needs the Platform SDK, if it isn't installed already. This can be
-done during installing Visual Studio, by selecting
-`Visual C++ MFC for x86 and x64` (and possibly
-`Visual C++ ATL for x86 and x64` depending on your version). If not, you
-can get download it as [MS Windows Platform SDK](https://developer.microsoft.com/en-us/windows/downloads/windows-sdk).
-
-Install the SDK by following the instructions as given.
-
-Dependencies for OpenTTD on Windows are handled via
-[vcpkg](https://github.com/Microsoft/vcpkg/). First you need to install vcpkg
-by following the `Quick Start` instructions of their
-[README](https://github.com/Microsoft/vcpkg/blob/master/README.md).
-
-After this, you can install the dependencies OpenTTD needs. We advise to use
-the `static` versions, and OpenTTD currently needs the following dependencies:
-
-- breakpad
-- liblzma
-- libpng
-- lzo
-- zlib
-
-To install both the x64 (64bit) and x86 (32bit) variants (though only one is necessary), you can use:
-
-```ps
-.\vcpkg install --triplet=x64-windows-static
-.\vcpkg install --triplet=x86-windows-static
-```
-
-You can open the folder (as a CMake project). CMake will be detected, and you can compile from there.
-If libraries are installed but not found, you need to set VCPKG_TARGET_TRIPLET in CMake parameters.
-For Visual Studio 2022 you also need to set CMAKE_TOOLCHAIN_FILE.
-(Typical values are shown in the MSVC project file command line example)
-
-Alternatively, you can create a MSVC project file via CMake. For this
-either download CMake from https://cmake.org/download/ or use the version
-that comes with vcpkg. After that, you can run something similar to this:
-
-```powershell
-mkdir build
-cd build
-cmake.exe .. -G"Visual Studio 17 2022" -DCMAKE_TOOLCHAIN_FILE="<location of vcpkg>\vcpkg\scripts\buildsystems\vcpkg.cmake" -DVCPKG_TARGET_TRIPLET="x64-windows-static"
-```
-
-Change `<location of vcpkg>` to where you have installed vcpkg. After this
-in the build folder are MSVC project files. MSVC can rebuild the project
-files himself via the `ZERO_CHECK` project.
-
-## All other platforms
-Minimum required version of CMake is 3.16.
-By default this produces a Debug build with assertations enabled.
-This is a far slower build than release builds.
-
-```bash
-mkdir build
-cd build
-cmake ..
-make
-```
-
-For more information on how to use CMake (including how to make Release builds),
-we urge you to read [their excellent manual](https://cmake.org/cmake/help/latest/guide/user-interaction/index.html).
-
-## CMake Options
-
-Via CMake, several options can be influenced to get different types of
-builds.
-
-- `-DCMAKE_BUILD_TYPE=RelWithDebInfo`: build a release build. This is
-   significantly faster than a debug build, but has far less useful information
-   in case of a crash.
-- `-DOPTION_DEDICATED=ON`: build OpenTTD without a GUI. Useful if you are
-   running a headless server, as it requires less libraries to operate.
-- `-DOPTION_USE_ASSERTS=OFF`: disable asserts. Use with care, as assert
-   statements capture early signs of trouble. Release builds have them
-   disabled by default.
-- `-DOPTION_TOOLS_ONLY=ON`: only build tools like `strgen`. Does not build
-   the game itself. Useful for cross-compiling.
-
-## Supported compilers
-
-Every compiler that is supported by CMake and supports C++20, should be
-able to compile OpenTTD. As the exact list of compilers changes constantly,
-we refer to the compiler manual to see if it supports C++20, and to CMake
-to see if it supports your compiler.
-
-## Compilation of base sets
-
-To recompile the extra graphics needed to play with the original Transport
-Tycoon Deluxe graphics you need GRFCodec (which includes NFORenum) as well.
-GRFCodec can be found at
-https://www.openttd.org/downloads/grfcodec-releases/latest.html.
-
-Having GRFCodec installed can cause regeneration of the `.grf` files, which
-are written in the source directory. This can leave your repository in a
-modified state, as different GRFCodec versions can cause binary differences
-in the resulting `.grf` files. Also translations might have been added for
-the base sets which are not yet included in the base set information files.
-To avoid this behaviour, disable GRFCodec (and NFORenum) in CMake cache
-(`GRFCODEC_EXECUTABLE` and `NFORENUM_EXECUTABLE`).
-
-## Developers settings
-
-You can control some flags directly via `CXXFLAGS` (any combination
-of these flags will work fine too):
-
-- `-DRANDOM_DEBUG`: this helps with debugging desyncs.
-- `-fno-inline`: this avoids creating inline functions; this can make
-  debugging a lot easier.
-- `-O0`: this disables all optimizations; this can make debugging a
-  lot easier.
-- `-p`: this enables profiling.
-
-Always use a clean buildfolder if you changing `CXXFLAGS`, as this
-value is otherwise cached. Example use:
-
-`CXXFLAGS="-fno-inline" cmake ..`

-
-## Bug reports
-
-A bug is a _demonstrable problem_ that is caused by the code in the repository.
-Good bug reports are extremely helpful, so thanks!
-
-Guidelines for bug reports:
-
-0. Please don't report issues with games where you changed NewGRFs mid-game. (This can be verified with the `gamelog` console command in-game.)
-
-1. Please don't report issues with modified versions of OpenTTD (patchpacks, unofficial ports, and similar).
-
-2. **Use the GitHub issue search** — check if the issue has already been
-reported.
-
-3. **Check if the issue has been fixed** — try to reproduce it using the latest `nightly` build of OpenTTD, available from https://www.openttd.org
-
-4. **Isolate the problem** — ideally create reproducible steps with an attached savegame and screenshots. Try to use few or no NewGRFs, AIs etc if possible.
-
-A good bug report shouldn't leave others needing to chase you up for more information.
-Please try to be as detailed as possible in your report.
-
-* What is your environment?
-* What steps will reproduce the issue?
-* Which operating system(s) experience the problem?
-* What would you expect to be the outcome?
-
-All these details will help people to fix any potential bugs.
-
-Example:
-
-> Short and descriptive example bug report title
->
-> A summary of the issue and the OS environment in which it occurs. If
-> suitable, include the steps required to reproduce the bug.
->
-> 1. This is the first step
-> 2. This is the second step
-> 3. Further steps, etc.
->
-> Attached savegame
-> Attached screenshots showing the issue
-> Crashlogs if the bug causes a crash
->
-> Any other information you want to share that is relevant to the issue being
-> reported. This might include the lines of code that you have identified as
-> causing the bug, and potential solutions (and your opinions on their
-> merits).
-
-
-## Feature requests
-
-Before opening a feature request, please take a moment to find out whether your idea fits with the [scope and goals](./CONTRIBUTING.md#project-goals) of the project.
-
-It's up to *you* to make a strong case to convince the project's developers of the merits of this feature.
-
-Please provide as much detail and context as possible.
-This means don't request for a solution, but describe the problem you see and how/why you think it should be fixed.
-
-For feature request we have a strict policy.
-
-Keeping issues around with "a good idea" or "not really a bug but we should maybe fix it" turns out to have the reversed effect: nobody looks at it anymore.
-
-Although we really appreciate feedback and ideas, we will close feature requests that we don't expect to fulfill in the next year.
-
-Many of those ideas etc do have a place on the [forums](https://www.tt-forums.net); and if enough people like it, someone will stand up and make it.
-
-It's usually best to discuss on [Discord](https://discord.gg/openttd) before opening a feature request or working on a large feature in a fork.
-Discussion can take time, but it can be productive and avoid disappointment. :)
-
-
-## Pull requests
-
-Good pull requests—patches, improvements, new features—are a fantastic help.
-
-Pull requests should fit with the [goals of the project](./CONTRIBUTING.md#project-goals).
-
-**Please do ask first** before embarking on any significant pull request (e.g. implementing features, refactoring code, porting to a different language), otherwise you risk spending a lot of time working on something that the project's developers might not want to merge into the project.
-
-Every pull request should have a clear scope, with no unrelated commits.
-
-[Code style](./CODINGSTYLE.md) must be complied with for pull requests to be accepted; this also includes [commit message format](./CODINGSTYLE.md#commit-message).
-
-Adhering to the following process is the best way to get your work included in the project:
-
-1. [Fork](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo) the project, clone your fork, and configure the remotes:
-
-```bash
-git clone https://github.com/<your-username>/OpenTTD.git openttd
-git clone https://github.com/OpenTTD/OpenTTD-git-hooks.git openttd_hooks
-cd openttd
-git remote add upstream https://github.com/OpenTTD/OpenTTD.git
-cd .git/hooks
-ln -s ../../../openttd_hooks/hooks/* .
-```
-
-2. If you cloned a while ago, get the latest changes from upstream:
-
-```bash
-git fetch upstream
-```
-
-3. Create a new topic branch (off the main project development branch) to
-contain your feature, change, or fix:
-
-```bash
-git checkout upstream/master -b <topic-branch-name>
-```
-
-4. Commit your changes in logical chunks. Please adhere to these [git commit message guidelines](./CODINGSTYLE.md#commit-message) or your code is unlikely to be merged into the main project.
-Use Git's [interactive rebase](https://docs.github.com/en/get-started/using-git/about-git-rebase) feature to tidy up your commits before making them public.
-
-5. Locally rebase the upstream development branch into your topic branch:
-
-```bash
-git fetch upstream
-git rebase upstream/master
-```
-
-6. Push your topic branch up to your fork the first time:
-
-```bash
-git push --set-upstream origin <topic-branch-name>
-```
-
-And any time after that:
-
-```bash
-git push
-```
-
-7. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/) with a clear title and description against the `master` branch.
-
-**IMPORTANT**: By submitting a pull request or patch, you agree to the [License](#license) and the [Privacy Notice](CONTRIBUTING.md#privacy-notice).
-
-
-### Pull request validation
-
-Continuous integration (CI) tools monitor pull requests, and help us identify build and code quality issues.
-
-The results of the CI tests will show on your pull request.
-
-By clicking on Details you can further zoom in; in case of a failure it will show you why it failed.
-In case of success it will report how awesome you were.
-
-Tip: [commit message format](./CODINGSTYLE.md#commit-message) is a common reason for pull requests to fail validation.
-
-
-### Are there any development docs?
-
-There is no single source for OpenTTD development docs. It's a complex project with a long history, and multiple APIs.
-
-A good entry point is [Development](https://wiki.openttd.org/en/Development/) on the OpenTTD wiki; this provides links to wiki documentation and other sources.
-
-The GitHub repo also includes some non-comprehensive documentation in [/docs](./docs).
-These include:
-- When to [change other languages and when not to](./docs/eints.md).
-- The [savegame format](./docs/savegame_format.md).
-- The [release process](./docs/releasing_openttd.md).
-- Some [notes on the link graph algorithm](./docs/linkgraph.md).
-- The [network game coordinator](./docs/game_coordinator.md).
-- How to use [the admin port for network games](./docs/admin_network.md), also useful for multiplayer server hosts.
-- The [performance metrics and logging features](./docs/logging_and_performance_metrics.md), also useful for add-on developers.
-- How [symbol server and analysis works](./docs/symbol_server.md).
-- And several miscellaneous files detailing internal data structures and graphics measurements and palettes.

-## Project goals
-
-### What are the goals of the official branch?
-
-The main goals of the official branch are:
-
-- Stay faithful to the original gameplay from Transport Tycoon Deluxe
-- Improve the user interface
-- Allow extending the gameplay with add-ons / mods via supported content APIs
-- Provide a (relatively) stable core for both players of the official branch, and for authors of add-ons and maintainers of patchpacks
-
-In contrast, extending or altering the gameplay of the base game is not encouraged.
-
-The rationale behind these goals is that people have different opinions about what OpenTTD is and what it should be.
-When it comes to gameplay, there are at least these groups of people:
-
-- *Model railway (mostly singleplayer)*: build "realistic" landscapes, roleplay a world, or even replicate historical scenarios
-- *Economical challenge (mostly singleplayer)*: run a business with economical challenges
-- *Transport challenge (singleplayer or cooperative multiplayer)*: build efficient track layouts with high cargo throughput and tons of vehicles
-- *Competitive speed run (competitive multiplayer)*: maximize some goal in some limited amount of time
-
-When it comes to gameplay features there are at least these groups of interests:
-
-- *Control freak:* micromanagement like conditional orders, refitting and loading etc.
-- *Casual:* automatisation like cargodist, path based signalling etc.
-
-To please everyone, the official branch tries to stay close to the original gameplay; after all, that is what brought everyone here.
-The preferred method to alter and extend the gameplay is via add-ons like NewGRF and GameScripts.
-
-For a long time, the official branch was also open to features which could be enabled/disabled, but the corner-cases that came with some configurations have rendered some parts of the code very complicated.
-Today, new features have to work with all the already existing features, which is not only challenging in corner cases, but also requires spending considerable more work than just "making it work in the game mode that I play".
-
-The preferred method to introduce new gameplay features is to extend the content APIs, supporting ever more add-on content / mods.
-
-This moves conflict-solving away from the codebase to content authors / players.
-It is more accepted for add-ons not working together than the base game not working with certain setting combinations.
-
-In general the game should allow anything that doesn't violate basic rules, but it should warn players if they take potentially dangerous or "stupid" actions.
-
-For example, players are not prevented from starting vehicles without orders, but will receive a warning about vehicles having too few orders.
-This lack of limitation has led to players challenging themselves to create networks where all vehicles have no orders, increasing gameplay possibilities.
-
-### I do not agree with the goals of the official branch, what can I do instead?
-
-Fork!  There is a rich history of experimental patches for OpenTTD.
-
-Many of these will never be accepted for core, but are creative and interesting ways to modify OpenTTD.
-
-Sometimes patches are combined into long-running patchpacks, modified OpenTTD versions which can be downloaded by anyone, or modified OpenTTD clients for dedicated multiplayer servers.
-
-One of the reasons to keep core relatively stable is to make life easier for patch authors and patchpack maintainers where possible.
-
-Patchpack discussions and related topics may be found in community sites such as [TT-Forums development section](https://www.tt-forums.net/viewforum.php?f=33).

-Other platforms may also work (in particular various BSD systems), but we don't actively test or maintain these.
-
-### 1.3.1) Legacy support
-
-Platforms, languages and compilers change.
-We'll keep support going on old platforms as long as someone is interested in supporting them, except where it means the project can't move forward to keep up with language and compiler features.
-
-We guarantee that every revision of OpenTTD will be able to load savegames from every older revision (excepting where the savegame is corrupt).
-Please report a bug if you find a save that doesn't load.
-
-## 1.4) Installing and running OpenTTD
-
-OpenTTD is usually straightforward to install, but for more help the wiki [includes an installation guide](https://wiki.openttd.org/en/Manual/Installation).
-
-OpenTTD needs some additional graphics and sound files to run.
-
-For some platforms these will be downloaded during the installation process if required.
-
-For some platforms, you will need to refer to [the installation guide](https://wiki.openttd.org/en/Manual/Installation).
-
-### 1.4.1) Free graphics and sound files
-
-The free data files, split into OpenGFX for graphics, OpenSFX for sounds and
-OpenMSX for music can be found at:
-
-- [OpenGFX](https://www.openttd.org/downloads/opengfx-releases/latest)
-- [OpenSFX](https://www.openttd.org/downloads/opensfx-releases/latest)
-- [OpenMSX](https://www.openttd.org/downloads/openmsx-releases/latest)
-
-Please follow the readme of these packages about the installation procedure.
-The Windows installer can optionally download and install these packages.
-
-### 1.4.2) Original Transport Tycoon Deluxe graphics and sound files
-
-If you want to play with the original Transport Tycoon Deluxe data files you have to copy the data files from the CD-ROM into the baseset/ directory.
-It does not matter whether you copy them from the DOS or Windows version of Transport Tycoon Deluxe.
-The Windows install can optionally copy these files.
-
-You need to copy the following files:
-- sample.cat
-- trg1r.grf or TRG1.GRF
-- trgcr.grf or TRGC.GRF
-- trghr.grf or TRGH.GRF
-- trgir.grf or TRGI.GRF
-- trgtr.grf or TRGT.GRF
-
-### 1.4.3) Original Transport Tycoon Deluxe music
-
-If you want the Transport Tycoon Deluxe music, copy the appropriate files from the original game into the baseset folder.
-- TTD for Windows: All files in the gm/ folder (gm_tt00.gm up to gm_tt21.gm)
-- TTD for DOS: The GM.CAT file
-- Transport Tycoon Original: The GM.CAT file, but rename it to GM-TTO.CAT
-
-## 1.5) Add-on content / mods
-
-OpenTTD features multiple types of add-on content, which modify gameplay in different ways.
-
-Most types of add-on content can be downloaded within OpenTTD via the 'Check Online Content' button in the main menu.
-
-Add-on content can also be installed manually, but that's more complicated; the [OpenTTD wiki](https://wiki.openttd.org/) may offer help with that, or the [OpenTTD directory structure guide](./docs/directory_structure.md).
-
-### 1.5.1) Social Integration
-
-OpenTTD has the ability to load plugins to integrate with Social Platforms like Steam, Discord, etc.
-
-To enable such integration, the plugin for the specific platform has to be downloaded and stored in the `social_integration` folder.
-
-See [OpenTTD's website](https://www.openttd.org), under Downloads, for what plugins are available.
-
-### 1.6) OpenTTD directories
-
-OpenTTD uses its own directory structure to store game data, add-on content etc.
-
-For more information, see the [directory structure guide](./docs/directory_structure.md).
-
-### 1.7) Compiling OpenTTD
-
-If you want to compile OpenTTD from source, instructions can be found in [COMPILING.md](./COMPILING.md).
