vscode-latex

LaTeX as a source-editing workflow

Abstract

Some LaTeX users already have a build system and a preferred viewer. They need source-editing support in VS Code without adopting another build orchestration workflow. vscode-latex documents that narrower purpose and integrates established formatters and ChkTeX with the editor. [1]

Source repository

1. The problem

An integrated LaTeX environment often combines editing, compilation, preview, and document navigation. That is useful when the extension owns the document workflow. A developer who already runs a build through another system may instead want the usual source-editor services to coexist with that system. [1]

Formatting and linting also need the configuration that belongs to the project. A per-editor default can conflict with a formatter's native configuration, particularly when a developer opens a file outside a workspace or works remotely.

2. The design

The extension supplies syntax highlighting and snippets, delegates linting to ChkTeX, and supports latexindent or tex-fmt for formatting. Remote and unsaved files are included in the documented editing workflow. Executable paths, timeouts, and lint delay are configurable. [1]

Configuration lookup walks the file's ancestors and supports explicit paths. When it finds a native formatter configuration, that configuration takes precedence over editor column-limit and indentation settings. Keeping that precedence explicit prevents two competing definitions of formatting policy. [1]

3. Alternatives

The relevant distinction is the requirement each approach serves.

3.1 LaTeX Workshop

The constraint
LaTeX Workshop deliberately provides an integrated environment with compilation, preview, completion, and more. A user whose build already lives elsewhere may not need that integrated workflow. [2]
Our approach
vscode-latex confines its purpose to source editing and delegates formatting and linting to external tools. [1]
The tradeoff
Choose LaTeX Workshop when integrated compilation, viewing, citations, or its broader IDE features are the desired experience.

3.2 Running latexindent and ChkTeX in a terminal

The constraint
The tools can process files directly, but a terminal invocation does not itself register VS Code formatting actions, snippets, or inline editor diagnostics.
Our approach
The extension adapts the tools to editor actions and applies a documented configuration lookup policy. [1]
The tradeoff
Direct CLI use remains useful in CI and scripts. The extension does not replace those checks or the external executables.

4. Boundaries & adoption

Install a supported formatter and ChkTeX, or use the extension's documented installation assistance. Native tool configuration can override editor defaults, so diagnose the discovered configuration before changing an editor setting. [1]

This project does not compile or preview a TeX document. Pair it with an existing build and viewer workflow. That scope is the reason to choose it; it is not evidence that integrated LaTeX environments are defective.
