## Development Environment
EmulationStation-DE is developed and compiled using both Clang/LLVM and GCC on Unix, Clang/LLVM on macOS and GCC (MinGW) on Windows. I may try to get Clang/LLVM working on Windows as well.

This Clang debug build is LLVM "native", i.e. intended to be debugged using the LLVM project debugger LLDB. The problem is that this is still not well integrated with VSCode that I use for development so I need to keep using GDB. But this is problematic as the libstd++ data required by GDB is missing in the binary, making it impossible to see the values of for instance `std::string` variables.

But this is problematic as the libstd++ data required by GDB is missing in the binary, making it impossible to see the values of for instance std::string variables.
It's possible to activate the additional debug info needed by GDB by using the flag `-D_GLIBCXX_DEBUG`. I've added this to CMakeLists.txt when using Clang, but this bloats the binary and makes the code much slower. Actually, instead of a 4% faster application startup, it's now 36% slower! The same goes for the binary size, instead of 17% smaller it's now 17% larger.
I'm expecting this to be resolved in the near future though, and as I think Clang is an interesting compiler, I use it as the default when working on the project (I sometimes test with GCC to make sure that it still builds the software correctly).

## Building on macOS
EmulationStation for macOS is built using Clang/LLVM which is the default compiler for this operating system. It's pretty straightforward to build software on this OS. The main deficiency is that there is no native package manager, but as there are several third party package managers available, this can be partly compensated for. The use of one of them, `Homebrew`, is detailed below.

The reason to not simply replace the BIOS and devices files with the new version is that we want to retain entries from all older MAME versions as otherwise older ROM sets used on older MAME versions will having missing information. This is so as the MAME project sometimes remove older entries when they're reorganizing the ROM sets. By merging the files we retain backwards compatibility but still support the latest MAME version. To clarify, this of course does not affect the emulation itself, but rather the filtering of BIOS and device files inside ES-DE. The mamenames.xml file containing the translation of MAME ROM names to the full game names does not suffer from this problem as it's cumulative, which is why it is simply overwritten.

## Configuration
**~/.emulationstation/es_systems.cfg:**
EmulationStation Desktop Edition ships with a comprehensive `es_systems.cfg` configuration file, and as the logic is to use a `%ROMPATH%` variable to locate the ROM files (with a corresponding setting in `es_settings.cfg`), normally you shouldn't need to modify this file to the same extent as previous versions of EmulationStation. Still, see below in this document on how to adjust the es_systems.cfg file if required.

Still, see below in this document on how to adjust the es_systems.cfg file if required.
Upon first startup of the application, if there is no es_systems.cfg file present, it will be copied from the template subdirectory inside the resources directory. This directory is located in the installation path of the application, for instance `/usr/local/share/emulationstation/resources/templates` on Unix, `/Applications/EmulationStation.app/Contents/Resources/resources/templates` on macOS and `C:\Program Files\EmulationStation\resources\templates` on Windows.

The template file will be copied to `~/.emulationstation/es_systems.cfg`. \
`~` is `$HOME` on Unix and macOS, and `%HOMEPATH%` on Windows.
The template file will be copied to **~/.emulationstation/es_systems.cfg**.
**Note:** Keep in mind that you have to set up your emulators separately from EmulationStation, the es_systems.cfg file assumes that your emulator environment is properly configured.
The tilde symbol **~** translates to **$HOME** on Unix and macOS, and to **%HOMEPATH%** on Windows.
On Unix it's assumed that RetroArch is using the default configuration directory location, i.e. the cores should be located in ~/.config/retroarch/cores. If you've installed RetroArch via a Snap package, make a symlink from the Snap .config directory:
```
ln -s ~/snap/retroarch/current/.config/retroarch ~/.config/
```
Keep in mind that you have to set up your emulators separately from ES-DE as the es_systems.cfg file assumes that your emulator environment is properly configured.

The es_systems.cfg file contains the system configuration data for ES-DE, written in XML format. This defines the system name, the full system name, the ROM path, the allowed file extensions, the launch command, the platform (for scraping) and the theme to use.

ES-DE will only check in your home directory for an es_systems.cfg file, for example **~/.emulationstation/es_systems.cfg**, but if this file is not present, it will attempt to install it from the systems template directory as explained earlier in this document.
The order EmulationStation displays systems reflects the order you define them in. In the case of the default es_systems.cfg file, the systems are listed in alphabetical order.
It doesn't matter in which order you define the systems as they will be sorted by the full system name inside the application, but it's still probably a good idea to add them in alphabetical order to make the file easier to maintain.
**Note:** A system *must* have at least one game present in its `path` directory, or ES will ignore it! If no valid systems are found, ES will report an error and quit.

The following variables are expanded by ES for the `command` tag:
The following variable is expanded for the `path` tag:
`%ROM%` - Replaced with absolute path to the selected ROM, with most Bash special characters escaped with a backslash.
`%ROMPATH%` - Replaced with the path defined in the setting ROMDirectory in es_settings.cfg.
The following variables are expanded for the `command` tag:
`%ROM%` - Replaced with the absolute path to the selected ROM, with most Bash special characters escaped with a backslash.
`%BASENAME%` - Replaced with the "base" name of the path to the selected ROM. For example, a path of `/foo/bar.rom`, this tag would be `bar`. This tag is useful for setting up AdvanceMAME.
`%COREPATH%` - The core file defined after this variable will be searched in each of the directories listed in the setting EmulatorCorePath (in es_settings.cfg). This is done until the first match occurs, or until the last directory is exhausted and no core file was found. This makes it possible to create a more general es_systems.cfg file but still support the variation between different operating systems and different types of emulator installations (e.g. installed via the OS repository, via Snap, compiled from source etc.). This is primarily intended for Unix as well as for RetroArch but it can also be used on macOS and Windows and for other emulators that utilizes discrete emulator cores. For macOS and Windows the EmulatorCorePath setting is blank by default, and for Unix it's set to the following value: `~/.config/retroarch/cores:~/snap/retroarch/current/.config/retroarch/cores:/usr/lib/x86_64-linux-gnu/libretro:/usr/lib64/libretro:/usr/lib/libretro:/usr/local/lib/libretro:/usr/pkg/lib/libretro`. Note that colons are used to separate the directories on Unix and macOS and semicolons are used on Windows. This path setting can be changed from within the GUI, as described in the [User Guide](USERGUIDE.md#other-settings-1). Never use quotation marks around the directories for this setting. It's strongly adviced to not add spaces to directory names, but if still done, ES-DE will handle this automatically by adding the appropriate quotation marks to the launch command.
`%ROM_RAW%` - Replaced with the unescaped, absolute path to the selected ROM. If your emulator is picky about paths, you might want to use this instead of %ROM%, but enclosed in quotes.
`%ROMRAW%` - Replaced with the unescaped, absolute path to the selected ROM. If your emulator is picky about paths, you might want to use this instead of %ROM%, but enclosed in quotes.
`%EMUPATH%` - Replaced with the path to the emulator binary. This is expanded either using the PATH environmental variable of the operating system, or if an absolute emulator path is defined, this will be used instead. This variable is mostly useful to define the emulator core path for Windows, as this operating system does not have a standardized program installation directory structure.
`%ESPATH%` - Replaced with the path to the EmulationStation binary. Mostly useful for portable emulator installations, for example on a USB memory stick.

Instead the application will look for any media matching the ROM filename. The media path where to look for game media is configurable either manually in **es_settings.cfg** or via the GUI. If configured manually in es_settings.cfg, it looks something like this:
`<string name="MediaDirectory" value="~/games/images/emulationstation" />`
```

The default game media directory is `~/.emulationstation/downloaded_media`.
The default directory is **~/.emulationstation/downloaded_media**
You can use ES's [scraping](http://en.wikipedia.org/wiki/Web_scraping) tools to populate the gamelist.xml files. There are two ways to run the scraper:
You can use ES-DE's scraping tools to populate the gamelist.xml files, or manually update individual entries using the metadata editor. All of this is explained in the [User guide](USERGUIDE.md).
* **If you want to scrape multiple games:** press the Start button to open the menu and choose the "SCRAPER" option. Adjust your settings and press "START".
* **If you just want to scrape one game:** find the game on the game list in ES and press the Select button. Choose "EDIT THIS GAME'S METADATA" and then press the "SCRAPE" button at the bottom of the metadata editor.
The gamelist.xml files are searched for in the ES-DE home directory, i.e. **~/.emulationstation/gamelists/\<system name\>/gamelist.xml**
You can also edit metadata within ES by using the metadata editor - just find the game you wish to edit on the gamelist, press Select, and choose "EDIT THIS GAME'S METADATA."
For example:
The switch `--ignore-gamelist` can be used to ignore the gamelists upon start of the application.
```

**File location and structure:**
**gamelist.xml file structure:**
ES checks for the `gamelist.xml` files in the user's home directory:
`~/.emulationstation/gamelists/[SYSTEM_NAME]/gamelist.xml`
The home directory can be overridden using the `--home` option from the command line, see above in this document for details regarding that.

**gamelist.xml reference:**
There are a few types of metadata:
There are a few different data types for the metadata which the string values in the gamelist.xml files are converted to during file loading:
* `string` - just text.
* `float` - a floating-point decimal value (written as a string).
* `integer` - an integer value (written as a string).
* `datetime` - a date and, potentially, a time. These are encoded as an ISO string, in the following format: "%Y%m%dT%H%M%S%F%q". For example, the release date for Chrono Trigger is encoded as "19950311T000000" (no time specified).

* `bool` - a true or false value
Some metadata is also marked as "statistic" - these are kept track of by ES and do not show up in the metadata editor. They are shown in certain views (for example, the detailed view and the video view both show `lastplayed`, although the label can be disabled by the theme).
Some metadata is also marked as "statistic" - these are kept track of by ES-DE and do not show up in the metadata editor. They are shown in certain views (for example, the detailed view and the video view both show `lastplayed`, although the label can be disabled by the theme).
There are two basic categories of metadata, `game` and `folders` and the metdata tags for these are described in detail below.
**\<game\>**
* `path` - string, the path to the game file, either relative to the %ROMPATH% variable or as an absolute path on the filesystem
* `name` - string, the displayed name for the game
* `sortname` - string, used in sorting the gamelist in a system, instead of `name`
* `desc` - string, a description of the game, longer descriptions will automatically scroll, so don't worry about the size
* `rating` - float, the rating for the game, expressed as a floating point number between 0 and 1. Fractional values will be rounded to 0.1 increments (half-stars) during processing
* `releasedate` - datetime, the date the game was released, displayed as date only, time is ignored
* `developer` - string, the developer for the game
* `publisher` - string, the publisher for the game
* `genre` - string, the genre(s) for the game
* `players` - integer, the number of players the game supports
* `favorite` - bool, indicates whether the game is a favorite
* `completed` - bool, indicates whether the game has been completed
* `kidgame` - bool, indicates whether the game is suitable for children, as used by the `Kid' UI mode
* `hidden` - bool, indicates whether the game is hidden
* `broken` - bool, indicates a game that doesn't work (useful for MAME)
* `nogamecount` - bool, indicates whether the game should be excluded from the game counter and the automatic and custom collections
* `nomultiscrape` - bool, indicates whether the game should be excluded from the multi-scraper
* `hidemetadata` - bool, indicates whether to hide most of the metadata fields when displaying the game in the gamelist view
* `launchcommand` - string, overrides the emulator and core settings on a per-game basis
* `playcount` - integer, the number of times this game has been played
* `lastplayed` - statistic, datetime, the last date and time this game was played
* `name` - string, the displayed name for the game.
* `desc` - string, a description of the game. Longer descriptions will automatically scroll, so don't worry about size.
* `rating` - float, the rating for the game, expressed as a floating point number between 0 and 1. ES will round fractional values to half-stars.
* `releasedate` - datetime, the date the game was released. Displayed as date only, time is ignored.
* `developer` - string, the developer for the game.
* `publisher` - string, the publisher for the game.
* `genre` - string, the (primary) genre for the game.
* `players` - integer, the number of players the game supports.
* `favorite` - bool, indicates whether the game is a favorite.
* `completed`- bool, indicates whether the game has been completed.
* `broken` - bool, indicates a game that doesn't work (useful for MAME).
* `kidgame` - bool, indicates whether the game is suitable for children, used by the `kid' UI mode.
* `playcount` - integer, the number of times this game has been played.
* `lastplayed` - statistic, datetime, the last date and time this game was played.
* `sortname` - string, used in sorting the gamelist in a system, instead of `name`.
* `launchcommand` - optional tag that is used to override the emulator and core settings on a per-game basis.
For folders, most of the fields are identical although some are removed. In the list below, the fields with identical function compared to the game files described above have been left without a description.
**\<folder\>**
* `name` - string, the displayed name for the folder.
* `desc` - string, the description for the folder.
* `developer` - string, developer(s).
* `publisher` - string, publisher(s).
* `genre` - string, genre(s).
* `players` - integer, the number of players the game supports.
* `path`
* `name`
* `desc`
* `rating`
* `releasedate`
* `developer`
* `publisher`
* `genre`
* `players`
* `favorite`
* `completed`
* `hidden`
* `broken`
* `nomultiscrape`
* `hidemetadata`
* `lastplayed` - statistic, for folders this is inherited by the latest game file launched inside the folder.
**Additional gamelist.xml information:**
* If a value matches the default for a particular piece of metadata, ES will not write it to the gamelist.xml (for example, if `genre` isn't specified, ES won't write an empty genre tag)
* If a value matches the default for a particular piece of metadata, ES-DE will not write it to the gamelist.xml file (for example, if `genre` isn't specified, an empty genre tag will not be written)
* A `game` can actually point to a folder/directory if the folder has a matching extension
* A `game` can actually point to a folder/directory if the folder has a matching extension, although this is exceedingly rare
* `folder` metadata will only be used if a game is found inside of that folder
* The `folder` metadata will only be used if a game file is found inside that folder, as empty folders will be skipped during startup even if they have metadata values defined for themselves
* ES will keep entries for games and folders that it can't find the game/ROM files for
* ES-DE will keep entries for games and folders that it can't find the game/ROM files for, i.e. it will not clean up the gamelist.xml files automatically when game files are missing
* The switch `--gamelist-only` can be used to skip automatic searching, and only display games defined in the system's gamelist.xml
* The switch `--gamelist-only` can be used to skip automatic searching, and only display games defined in the gamelist.xml files
* The switch `--ignore-gamelist` can be used to ignore the gamelist upon start of the application
* The switch `--ignore-gamelist` can be used to ignore the gamelist upon start of the application (mostly useful for debugging purposes)
## Custom event scripts
There are numerous locations throughout ES where custom scripts will be executed if the option to do so has been enabled in the settings. You'll find the option on the Main menu under **Other settings**. By default it's deactivated so be sure to enable it to use this feature.

As an example, let's create a log that will record the start and end time for each game we play, letting us see how much time we spend on retro-gaming.

The events when the game starts and ends are called **game-start** and **game-end** respectively. Finding these event names is easily achieved by starting ES with the **--debug** flag. If this is done, all attempts to execute custom event scripts will be logged to es_log.txt, including the event names.

If the theme supports it, there's a gamelist information field displayed in the gamelist view, showing the number of games for the system (total and favorites) as well as a folder icon if a folder has been entered. When applying any filters to the gamelist, the game counter is replaced with the amount of games filtered, as in 'filtered / total games', e.g. '19 / 77'. If there are game entries in the filter result that are marked not to be counted as games, the number of such files will be indicated as 'filtered + filtered non-games / total games', for example '23 + 4 / 77' indicating 23 normal games, 4 non-games out of a total of 77. Due to this approach it's theoretically possible that the combined filtered game amount exceeds the number of counted games in the collection, for instance '69 + 11 / 77'. This is not considered a bug and is so by design. This gamelist information field functionality is specific to EmulationStation Desktop Edition so older themes will not support this.

By default, ES-DE will search using the metadata name of the game. If no name has been defined via scraping or manually using the metadata editor, this name will correspond to the physical file name minus all text inside either normal brackets **()** or square brackets **[]**. So for example the physical filename **Mygame (U) [v2].zip** will be stripped to simply **Mygame** when performing the scraping.

The behavior of using the metadata name rather than the file name can be changed using the setting **Search using metadata name**.
Note that there is an exception to this behavior for arcade games (MAME and Neo Geo). For ScreenScraper the short MAME names are used by default as this scraper service fully supports that. For TheGamesDB the short names are instead expanded to the full games names using a lookup in the MAME name database supplied with the ES-DE installation. It's possible to override this automatic behavior by using the _Refine Search_ button in the scraper GUI if the search did not yield any results, or if the wrong game was returned. In general though, searching for arcade games is very reliable assuming the physical game files follow the MAME name standard.

Somewhat confusingly the terms **theme** and **theme set** are used to refer to the same thing. The technically correct term for what you apply to the application to achieve a different look is actually _theme set_ as it's a collection of a number of themes for a number of game systems. The supplied rbsimple-DE is an example of such a theme set. But in this guide and in other EmulationStation resources on the Internet, the term theme is often used to refer to the same thing as a theme set. As long as you are aware of the distinction, it doesn't really matter which term is used.
>>>
Note that this Desktop Edition fork adds additional features to the themes and more still will be added in future versions. This means that you may not get the full benefits of the application if you're using a different theme set. But effort is spent trying to make ES-DE backwards compatible with the available themes used by other EmulationStation versions, even if the functionality they provide is limited.
Themes are most easily installed in your ES-DE home directory, i.e. **~/.emulationstation/themes**. By just adding the theme sets there, one folder each, they will be found by ES-DE during startup and you can then choose between them via **UI Settings** on the main menu.
