# axx lsp

> Serve feature-file editing to editors over the Language Server Protocol (stdio)

Source: https://axx.nimbusxr.us/references/cli/axx-lsp/

Start a language server on stdin/stdout for feature files: undefined,
ambiguous and misused steps and Gherkin syntax errors as you type, step
completion, step documentation on hover, going to a step's definition,
highlighted step parameters, and links to, path completion for and warnings
about missing files that steps name.

Editors start it themselves: the Axx plugin for IntelliJ IDEA and the Axx
extension for VS Code do, and other editors can run "axx lsp" for *.feature
files. The steps come from the project's packs, custom packs included; restart
the server after changing a custom pack.
