RegReplace

• This is a useful sublime extension for running multiple regex expressions on a single file through a keybind
• RegReplace rules (for Mac),

/Users/<user>/Library/Application Support/Sublime Text/Packages/User/reg_replace_rules.sublime-settings

{
    "replacements": {
        "rule1": {
            "find":"",
            "replace":"",
            "greedy": true
        },
        "rule2": {
            "find":"",
            "replace":"",
            "greedy": true
        }
    }
}

where

"[\\n\\s]*" = any newline or space
"(string1|string2)" = looking for "string1" or "string2"
"[\\n\\s]*\"(property1|property2)\":[\\n\\s]*{[\\n\\w\"\\:\\,. ]*}," = replace entire json of "property1 = { stuff: stuff, },"

• RegReplace keybind (for Mac),

/Users/<user>/Library/Application Support/Sublime Text/Packages/User/Default (OSX).sublime-keymap

[
    {
        "keys": ["option+ctrl+r"],
        "command": "reg_replace",
        "args": {"replacements": ["rule1","rule2"]}
    }
]
