Quote each element of a list.

Select a comma-separated list. Press ctrl+shift+' (macOS: cmd+shift+') or open Command Palette and enter Quote List.

foo, bar baz, https://foo.bar, 🦆

becomes

"foo", "bar baz", "https://foo.bar", "🦆"

For single quotes, use ctrl+' (macOS: cmd+'). For backticks, use ctrl+alt+' (macOS: cmd+alt+'). You can also specify custom quotes and separators (see below).

Leading and trailing whitespace (or lack thereof) between items is preserved.

foo,bar,baz

becomes

"foo","bar","baz"

and

foo,
bar,
baz

becomes

"foo",
"bar",
"baz"

To specify separators and quotes on the fly from user input, select text and press alt+shift+', or open Command Palette and enter Quote List by Input. You will be prompted to provide the input separator (a JavaScript-style regular expression string to match the desired separator in the selection), the output separator (a string to replace each separator in the selection), and the quote (a string to be placed on the left and right of each item in the selection). For example, to convert a tab-separated list into a single-quoted list separated by commas, with each element on a new line:

starting with:

a	b	c

providing the following values:

yields:

'a',
'b',
'c'

By default, if you enter (, {, or [ as the quote string from user input, that string will be the left quote and the right quote will be ), }, or ], respectively. You can modify this behavior by providing quoteList.surroundingPairs in settings.json. The default is:

 "quoteList.surroundingPairs": {
    "(": ")",
    "{": "}",
    "[": "]"
 } 

If Quote List is invoked and the default (or keybinding argument, see below) input separator is not found in the selection, a series of fallback separators will be tried. This behavior can be modified by providing quoteList.fallbackSeparators in settings.json (or as an argument in a keybinding, see below). This is an object of key-value pairs of strings, where each key is an input separator regular expression and each value is a corresponding output separator string. Each pair is tried in order until one of the input separators is found in the selection. The default is:

"quoteList.fallbackSeparators": {
    "\\t": ", ",
    "\\n": ",\n",
    ":": ", ",
    ";": ", ",
    "\\|": ", ",
    "\\^": ", ",
    "~": ", ",
    " +": ", "
}

To create a new keybinding with custom quotes and separators (or override existing keybindings), add the following to keybindings.json, replacing the value for key as desired, and replacing the values for each key in args (or omitting the key to use the default) as desired:

{
    "command": "extension.quoteList",
    "key": "ctrl+alt+shift+'",
    "when": "editorTextFocus && !editorReadonly",
    "args": {
        "quote": "/",
        "inputSeparator": "\\n",
        "outputSeparator": ";",
        "fallbackSeparators": {
            "\\t": ":",
            "\\s+": "|"
        }
    }
}

You can create as many keybindings with different args for Quote List as you like in this way. If you want different left and right quotes, you can specify them like so, in lieu of args.quote:

"args": {
    "quoteLeft": "<",
    "quoteRight": ">"
}
