⚠

Only available in Development branch(es) until its release with Arma 3 patch v2.10.

Description

Description:

Loads the given file as a Config, allowing easy processing of the config file contents using commands such as configClasses, configProperties, >>, etc. It can load .rvmat, .bisurf, .cpp, .bin, .sqm, and description.ext files (both binarized and unbinarized configs are supported).

⚠

Loading a config can be very slow. The config should only be loaded once and cached. For example, the result can be stored in a HashMap of File Path - Config pairs. (See Example 2)

Groups:

Config

Syntax

Syntax:

loadConfig path

Parameters:

path: String - Path to the file, which should be in a valid config format.

Return Value:

Config - Loaded config. Returns configNull if the file doesn't exist.

Examples

Example 1:

private _cfg = loadConfig "a3\data_f\default_super.rvmat"; // note: very slow! ~0.1200 ms on tested system getText (_cfg >> "Stage2" >> "uvSource");

Example 2:

// Using a hashmap to cache loaded configs, since loading configs is very slow and should be done once. _fnc_loadConfig = { params ["_path"]; // initialize cache if not initialized yet if (isNil "TAG_configCache") then { TAG_configCache = createHashMap; }; private _cfg = TAG_configCache getOrDefault [_path, configNull]; // if path doesn't exist in the cache or cfg is null, load the config if (isNull _cfg) then { _cfg = loadConfig _path; TAG_configCache set [_path, _cfg]; }; _cfg; }; // the first call will be slow (~0.1200 ms), but subsequent calls are fast (~0.0050 ms) ["a3\data_f\default_super.rvmat"] call _fnc_loadConfig;

Example 3:

// Converting a config into hashmap _fnc_convertClass = { params ["_cfgClass"]; private _result = createHashMap; private _props = configProperties [_cfgClass, "true", true]; // Note: Hashmaps are case-sensitive. So configName cases have to be consistent (e.g. all lowercase) { if (isNumber _x) then {_result set [toLowerANSI configName _x, getNumber _x]; continue; }; if (isText _x) then {_result set [toLowerANSI configName _x, getText _x]; continue; }; if (isArray _x) then {_result set [toLowerANSI configName _x, getArray _x]; continue; }; } forEach _props; private _classes = "true" configClasses _cfgClass; { _result set [toLowerANSI configName _x, _x call _fnc_convertClass]; } forEach _classes; _result }; private _cfg = loadConfig "mission.sqm"; private _cfgMap = _cfg call _fnc_convertClass; // The following expression is similar to getNumber(_cfg >> "EditorData" >> "moveGridStep") // Notice that all strings are lowercase (which is how they were stored in hashmap) _cfgMap get "editordata" get "movegridstep";

When trying to load a terrain surface name, like you get from Ammo Eventhandlers when you hit the terrain, you can simply use

_config = configFile >> "CfgSurfaces" >> _surfaceName;

You can recognize surface names by them not having any \ path seperators in them, they usually start with gdt, for example "gdtvrsurface01".
