Converts single to double or double to single quotes. Attempts to preserve correct escaping, though this could be improved I'm sure.

Using Package Control, install "ChangeQuotes" or clone this repo in your packages folder.

I recommended you add key bindings for the commands. I've included my preferred bindings below. Copy them to your key bindings file (⌘⇧,).

Copy these to your user key bindings file.

{ "keys": ["ctrl+shift+'"], "command": "change_quotes" },

Put your cursor inside the text that is in quotes and then execute the command to replace the quotes. No selection needed.

Different languages have different quotes, and this plugin tries to support them all!

Open up ChangeQuotes.sublime-settings to see the default config. You can get there from the menu bar: Preferences > Package Settings > Change Quotes > Settings - Default

There are two per-language settings you should pay attention to:

prefixes - This helps with the string searching; in python, a string can start with an identifier like u or r, and these will be "skipped" when changing quotes.

quotes - This list-of-lists defines all the quote characters that can be cycled. If you are using ES6, and want to add support for backtick-strings / interpolation-strings, you just need to add the backtick character to this list!

// without backtick-strings:
"source.js": {
  "quotes": [["'", "\""]]
}
// with backtick-string support (ES6-only):
"source.js": {
  "quotes": [["'", "\"", "`"]]
}

change_quotes: Converts from single to double quotes. Uses the Sublime Text grammar parsing, so it doesn't always "find" the quotes, for instance MarkDown doesn't define special "string" syntax, and so this plugin can't be used. The upside is we don't have to write / maintain a complex matching quote algorithm.
