IBIS I/O Buffer Model Highlighter
vscode-ibis provides lightweight language support for IBIS (I/O Buffer Information Specification) .ibs files.
The first version focuses on fast, standard VS Code language-extension behavior using a TextMate grammar. It does not include parsing, validation, linting, completion, or semantic analysis yet.
Features
- Automatically recognizes
.ibs files as IBIS.
- Highlights IBIS section keywords such as
[Component], [Model], [Pin], [Model Selector], [Submodel], [Pullup], [Pulldown], [Ramp], and waveform/table sections.
- Highlights comments beginning with
|, including inline comments after data.
- Highlights numeric values, scientific notation, and common IBIS-style units and SI prefixes.
- Includes base language configuration for comments, brackets, quote handling, word selection, and folding markers.
- Works as a standard VS Code language extension with no runtime activation code.

Local Development
Install dependencies:
npm install
Open this folder in VS Code.
Press F5 and select Run Extension.
In the Extension Development Host window, open a .ibs file or create a new file and set the language mode to IBIS.
Packaging
Install dependencies first, then run:
npm run package
This runs vsce package and creates a .vsix file in the project root.
You can install the generated package locally with:
code --install-extension vscode-ibis-0.0.1.vsix
