Removing unused languages

[ajtruckle]

In your previous version I was able to use this code snippet to remove languages from the drop-down list:

function mm_ejs_languages($langs){
    unset ($langs['Java']);
    unset ($langs['Javascript']);
    unset ($langs['JSON']);
    unset ($langs['Python']);
    unset ($langs['Ruby']);
    unset ($langs['C']);
    unset ($langs['RUST']);
    unset ($langs['LUA']);
    unset ($langs['Matlab']);
    unset ($langs['NSIS']);
    unset ($langs['Diff']);
    unset ($langs['VHDL']);
    unset ($langs['Avr Assembly']);
    unset ($langs['Generic Assembly']);
    unset ($langs['Kotlin']);
    unset ($langs['Squirrel']);
    return $langs;
}

// add a custom filter to modify the language list
add_filter('enlighter_languages', 'mm_ejs_languages');

This no longer works with v4 so I am getting all languages.

the internal data structure has changed, you've to modify your code (keys/values swapped)

Array
(
    [generic] => Generic Highlighting

Thanks for that explanation. So, if I adjust my code like this it would be correct, right?

function mm_ejs_languages($langs){
    unset ($langs['java']);
    unset ($langs['js']);
    unset ($langs['json']);
    unset ($langs['python']);
    unset ($langs['ruby']);
    unset ($langs['c']);
    unset ($langs['rust']);
    unset ($langs['lua']);
    unset ($langs['matlab']);
    unset ($langs['nsis']);
    unset ($langs['diff']);
    unset ($langs['vhdl']);
    unset ($langs['avrasm']);
    unset ($langs['asm']);
    unset ($langs['kotlin']);
    unset ($langs['squirrel']);
    return $langs;
}

// add a custom filter to modify the language list
add_filter('enlighter_languages', 'mm_ejs_languages');

of course, this should work as expected

[AndiDittrich]

the docs have also been updated

[ajtruckle]

Thanks for latest version. :)

[ajtruckle]

Sorry for being so dumb! I can't remember how to find out the official new language name ids in the default array so I can unset them (like R and RouterOS). I tried to find in the docs but could not locate. Sorry to bring this up again! Thanks for your good work!

[AndiDittrich]

look into LanguageManager.php or use print_r
