DBC Language Syntax

This extension provides basic syntax highlighting, bracket completion, code snippets and lexer/parser errors for the Vector DBC file format. This is created to work with version 2 of the Vector DBC file format.

Although DBC files are often programmatically generated, it can be useful to more easily read the DBC file itself in a plaintext format. Syntax highlighting is handled locally through VSCode's integrated TextMates language parsing engine, using PCRE regular expressions to match syntax.
