A Sublime Text 4 package for the Python-powered shell xonsh
extending the default Python package with xonsh-specific contexts

Introduction

This package adds support for the xonsh language (for files with .xsh and .xonshrc extensions) by extending the syntax definitions from the default Python package with the following xonsh-specific contexts:

  • Variables: $variableA, including the environment ${...}
  • Subprocess operators: $() $[] ${} @() @$() (and !() ![])
  • Search functions: @functionB`search_string`
  • Builtin functions: abbrevs() aliases() compilex() execx() evalx() events() print_color() exit() printx()

… and copying all the other relevant elements (Snippets, Comments, Completion Rules, Indentation Rules, Symbol List, and the Default keymap) & re-scoping them to work in the xonsh syntax

Installation

  • Via Package Control: open Command PalettePackage Control: Install Packagexonsh
                                            Ctrl/⌘Cmd⇧ShiftP

  • Manually: clone this repository to your Packages directory and rename it to xonsh

cd /path/to/sublime/packages/directory
git clone https://github.com/eugenesvk/sublime-xonsh.git
mv sublime-xonsh xonsh

Usage

Open any xonsh file (e.g. syntax_example_screen.xsh) and verify that the selected syntax is Xonsh and xonsh-specific contexts are properly scoped[1] and highlighted, maybe like so (depending on your color scheme):

[1]: scope naming is supposed to conform to that of the default Python package and ST's scope naming guidelines

Examples of supported syntaxes: variables

| Example | Description | :————– | :———- | $ | Match a single variable definition symbol to help with completions | $varA=[1,2] | Regular variable | $varA[0] | Variable indexing | $varA[$varB] | Variable inside an index | funct($varB) | Variable inside a function | f"{$varA}" | Variable inside a function string | ${...} | The environment itself

Examples of supported syntaxes: subprocess operators

Example Description
@$(which ls) Command Substitution
@('echo', 1) Python Evaluation
$(echo 1) Captured Subprocess
!(echo 1)
$[echo 1] Uncaptured Subprocess
![echo 1]

Keybindings

This plugin adds two keybindings for the xonsh scope: "/' that auto-pair double/single quotes even after string modifiers

Known issues

  • Only works in Sublime Text 4 since build 4075 (10 July 2020) since it's using meta_append/meta_prepend APIs
  • Illegal Python names that would be legal in a subprocess mode are nonetheless scoped as illegal since there is no differentiation between Python and subprocess modes:
    e.g. as in echo "$HOME" as well as '$HOME'
    As a workaround use "quotes" or dim/remove error highlighting for source.xonsh invalid.illegal.name
