Abaqus for Zed

Abaqus is a finite element analysis (FEA) solution from Dassault Systèmes SIMULIA, used extensively in my professional work and research. This extension adds editor support for its input files (.inp, .inc, .incl) to the Zed editor: syntax highlighting, an outline of the model, Vim text objects and snippets, built on a new Tree-sitter grammar. It helps you read and edit input decks; it doesn't run Abaqus and doesn't need an Abaqus installation.

An Abaqus input file open in Zed with the extension: keywords such as *Part, *Step and *Material in colour, parameter names and values, numbers, comments and data lines each highlighted differently.

Features

Syntax highlighting for comments, *Keywords, parameter names and values, YES/NO flags, numbers (including Fortran-style 2.5D+1), strings, <parameter> references and data lines
Structural keywords stand out: *Part, *Assembly, *Instance, *Step and their *End lines get their own colour
Outline of parts, assemblies, instances and steps, nested, and every named definition: materials, sets, surfaces, amplitudes and more
Vim motions and text objects: ]] / [[ jump between parts, instances and steps; ]m / [m between keyword blocks; af selects a whole block, if only its data lines
67 snippets: type * and a keyword such as node, material, static or contact pair; Tab moves through the fields
Comment toggling with Ctrl+/, using **
Large files: a 28 MB, 550,000-line mesh parses in a few seconds in the background, with highlighting on
Free and open source under the MIT licence; source, grammar and tests on GitHub

Install

The extension isn't in Zed's extension registry yet, so you install it from the GitHub repository as a dev extension. You need Zed and git; Zed compiles the grammar itself.

1. Clone the repository

Anywhere you like; Zed reads the extension from this folder.

2. Install it in Zed

Open the command palette (Ctrl+Shift+P, or Cmd+Shift+P on macOS), run zed: install dev extension and choose the zed-abaqus folder. After a moment, Abaqus appears on the Extensions page.

3. Open an input file

Open an .inp file; the status bar should say Abaqus. To update later, run git pull in the folder and press Rebuild on the Extensions page.

# get the extension
$ git clone https://github.com/QutritLogic/zed-abaqus.git

# update it later, then Rebuild in Zed
$ cd zed-abaqus && git pull

Source code and documentation

Troubleshooting, recolouring, known limits and how to change the grammar are in the README on GitHub. Issues and pull requests are welcome there.
