XferLang VS Code Extension
This extension provides syntax highlighting and basic editor help for XferLang files in Visual Studio Code, aligned with the current core language implementation.
Features
- Processing instructions (document, dynamicSource, chardef, if, script, let, defined, id, tag)
- Explicit + compact forms for: strings, numbers (int/long/decimal/double), booleans, null, objects, arrays, tuples
- Signed numeric literals (+ / -) in implicit, compact, and explicit forms
- Dynamic elements (|key| / <| key |>) and references (leading underscores) highlighting
- Interpolated elements inside quoted strings
- Hexadecimal and binary numeric forms ($, %, #$, #%, &$, &%)
- Auto-closing & surrounding pairs for all specifiers and collection delimiters
- On-enter smart indent/outdent for {}, [], (), and their explicit <...> counterparts plus processing instructions
- Basic syntax resilience: nested comments & delimiter length variations
Usage
Open any .xfer file to activate. Most constructs highlight as you type; increasing a delimiter run (adding more of the same specifier character) is treated uniformly.
