Sublime text 3. Enable Emmet in JSX files with Sublime React plugin

# Sublime Emmet JSX Reactjs.md

Problem

• Using emmet in jsx files
• Emmet expands text when js autocomplete needed
• Using className instead of class

How it works

• Install plugin RegReplace
• Install plugin Chain Of Command
• Merge files from this gist to your Packages/User directory

Emmet will expand

• .someClass
• a.someClass (list of tags look in Default (OSX).sublime-keymap, now it's a|div|span|p|button)
• div>p

Preferences - Key Bindings - User.sublime-keymap

[
 { "keys": ["tab"], "command": "expand_abbreviation_by_tab", "context":
    [
        { "operand": "source.js", "operator": "equal", "match_all": true, "key": "selector" },
        { "match_all": true, "key": "selection_empty" },
        { "operator": "equal", "operand": false, "match_all": true, "key": "has_next_field" },
        { "operand": false, "operator": "equal", "match_all": true, "key": "auto_complete_visible" },
        { "match_all": true, "key": "is_abbreviation" }
    ]
}
]

reg_replace.sublime-settings

{
    "replacements": {
        "js_class": {
            "find": " class=\"",
            "replace": " className=\"",
            "greedy": true,
            "case": false
        }
    }
}

Fantastic, it works for me after tried Wes's post.
Thanks
