Symbol Complete

This is a very simple VSCode extension which converts a given set of (regular expression) patterns into a user-specified list of symbols.

Usage

Install this extension by searching 'Symbol Complete' in VSCode extensions. Open up a new file and type something like |-->| and it should convert to ⟶ automatically.

Extension Settings

Patterns are written between a start symbol and an end symbol. Both default to |. If | is awkward on your keyboard layout, change them (see #4); the change applies immediately, no reload needed:

{
    "symbol-complete.startSymbol": ".",
    "symbol-complete.endSymbol": "."
}

Now .-->. becomes ⟶ and .lambda. becomes λ. The symbols are literal text, so . means a dot, not "any character". Start and end may differ and may be several characters long.

The table of patterns lives in symbol-complete.symbols. Keys are the regular expression between the symbols, values are the replacement:

{
    "symbol-complete.symbols": {
        "lambda": "λ",
        "\\-\\-\\>": "⟶"
    }
}

Your entries are merged with the built-in table (all Greek letters, arrows, set theory and logic operators; see package.json for the full list).

symbol-complete.replacements takes raw regular expressions matched exactly as written, without the start/end symbols. Entries from earlier versions, such as "\\|lambda\\|": "λ", keep working there, and it is the place for delimiter-free patterns:

{
    "symbol-complete.replacements": {
        "\\.\\.\\.": "…"
    }
}

When more than one pattern matches at the cursor, the longest wins.

This extension also works with multiple selections.
