G-code Syntax

Description

This extension offers syntax highlighting and a small collection of code snippets for G-code-based CNC programs.

The extension is currently based on using a Mitsubishi 700 Series CNC control (lathe system), which is a "Fanuc-like" control.

Features

Syntax Highlighting

• Highlighting uses colors based on the current theme. Unfortunately, most themes (if any?) will not target many elements of a CNC program. I had to mostly apply scopes that were not semantically accurate to get the syntax highlighting that I wanted. There will be some themes where the highlighting does not look so good. This is because there is no consistency in the scopes that the various themes are targeting.

• An attempt was made to highlight the X, Y, & Z coordinate positions with unique colors. Position-based words for these axes are currently highlighted using the following scopes:

  • X & U: string
  • Y & V: support.class
  • Z & W: storage.type

Code Snippets

Convenient snippets for common G-code commands and patterns:

• G70 | G71 | G72 | G73

• op-description: inserts a sequence # followed by a comment

  • example: N1000 (FACE OFF)

• star-padded-comment: inserts a comment padded with stars

  • example: (*** A COMMENT ***)

• dash-padded-comment: inserts a comment padded with dashes

  • example: (--- ANOTHER COMMENT ---)

Commands

• Toggle Line Comment ctrl+/: Toggles parentheses-based line comments for the current line(s)/selected text.

File Extensions

The above features will be applied to files with the following extensions:

[".nc", ".cnc", ".eia", ".gcode"]

Additional file extensions can be included by adding the following to your user or workspace settings.json:

{
  "files.associations": {
    "*.ext1": "gcode",
    "*.ext2": "gcode",
    "*.ext3": "gcode"
  }
}
// This will associate files with extensions of ".ext1", ".ext2", and ".ext3"

Requirements

No requirements at this time.
