Question

I’d like to get the SubLime Linter plugin (https://github.com/Kronuz/SublimeLinter) to recognize Ruby 1.9 syntax. Has anybody been able to get this to work in SublimeText 2?

Here is my current default settings file:

/*
    SublimeLinter default settings
*/
{
    /*
        Sets the mode in which SublimeLinter runs:

        true - Linting occurs in the background as you type (the default).
        false - Linting only occurs when you initiate it.
        "load-save" - Linting occurs only when a file is loaded and saved.
    */
    "sublimelinter": true,

    /*
        Maps linters to executables for non-built in linters. If the executable
        is not in the default system path, or on posix systems in /usr/local/bin
        or ~/bin, then you must specify the full path to the executable.
        Linter names should be lowercase.

        This is the effective default map; your mappings may override these.

        "sublimelinter_executable_map":
        {
            "perl": "perl",
            "php": "php",
            "ruby": "ruby"
        },
    */
    "sublimelinter_executable_map":
    {
    },

    /*
        Maps syntax names to linters. This allows variations on a syntax
        (for example "Python (Django)") to be linted. The key is
        the base filename of the .tmLanguage syntax files, and the value
        is the linter name (lowercase) the syntax maps to.
    */
    "sublimelinter_syntax_map":
    {
        "Python Django": "python"
    },

    // An array of linter names to disable. Names should be lowercase.
    "sublimelinter_disable":
    [

        a linter is run when the "sublimelinter" setting is true. This allows
        you to have background linting active, but defer the actual linting
        until you are idle. When this value is greater than the built in linting delay,
        errors are erased when the file is modified, since the assumption is
        you don't want to see errors while you type.

    "sublimelinter_delay": 0,

    // If true, lines with errors or warnings will be filled in with the outline color.
    "sublimelinter_fill_outlines": false,

    // If true, lines with errors or warnings will have a gutter mark.
    "sublimelinter_gutter_marks": false,

    // If true, the find next/previous error commands will wrap.
    "sublimelinter_wrap_find": true,

    // If true, when the file is saved any errors will appear in a popup list
    "sublimelinter_popup_errors_on_save": false,

    ],

    /*
        If you use SublimeLinter for pyflakes checks, you can ignore some of the "undefined name xxx"
        errors (comes in handy if you work with post-processors, globals/builtins available only at runtime, etc.).
        You can control what names will be ignored with the user setting "pyflakes_ignore".

        Example:

        "pyflakes_ignore":
            [
                "some_custom_builtin_o_mine",
                "A_GLOBAL_CONSTANT"
            ],
    */
    "pyflakes_ignore":
    [
    ],

    /*
        Ordinarily pyflakes will issue a warning when 'from foo import *' is used,
        but it is ignored since the warning is not that helpful. If you want to see this warning,
        set this option to false.
    */
    "pyflakes_ignore_import_*": true,

    // Objective-J: if true, non-ascii characters are flagged as an error.
    "sublimelinter_objj_check_ascii": false

I was able to get it to work using the absolute path to my ruby 1.9 executable. I’m using rbenv, so to get the path I ran rbenv which ruby, you might need to put in /usr/local/bin/ruby or /usr/local/bin/ruby19.

This is how my sublimelinter default setting looks like (you can put this into a project-specific file too if you prefer:)

Preferences -> Package Settings -> SublimeLinter -> Settings - User

"sublimelinter_executable_map":
{
    "ruby": "~/.rbenv/versions/1.9.3-p0/bin/ruby"
},
