A language server for zc.buildout

Project description

A Language Server for zc.buildout.

This language server is implemented using pygls.

Installation

Standalone

Needs a python >= 3.7.

python -m pip install zc.buildout.languageserver

Then configure your editor to run buildoutls ( or python3 -m buildoutls ).

From vscode extension

On activation, the extension automatically installs the extension on the python configured in the extension preferences.

The automatic installation does not seem to work with theia and the python egg has to be installed beforehand.

Features

Completions

  • ${ complete sections.
  • ${section: complete section's options. If section uses a known recipe, dynamic options from the recipe are also completed.
  • ${buildout:extends} completes filenames.
  • ${buildout:parts} and <= option completes parts.

Diagnostics

  • non existant section and options in ${section:option} references.
  • required options not defined for a a few "known recipes".
  • python package listed in [versions] with known vulnerabilities

Symbols

  • Sections and options are shown are displayed in outline as symbols.

Links

  • ${buildout:extends} are links.

Go to definitions

  • from ${section:options} we can go to the location where option is defined in section, or to section header if it's not defined.
  • from <= section we can go to section.
  • from ${buildout:extends} we can go to the extended profile.

Hover

  • Hover on an option show the option value.

Find references

  • Find references of the current symbol. A bit simple, it only look for references and does not check if profiles really extends each other. It does not look in templates either.

Code actions

  • update a python package from [versions] to its latest version on pypi
  • compute the md5sum of an url

Template support

  • "current" buildout profile is guessed, then completions and diagnostics should work on any files.

Jinja2 support

  • Jinja syntax is syntax highlighted and jinja syntax markers are ignored when parsing buildout.

SlapOS support

  • SlapOS instance buildout (ie. buildout generated by buildout) is understood, ${ and $${ are treated separatly for completions and diagnostics.
