Hi I've run into a new problem with the restructuredtext extension. Here's the information about it.


  • Extension version: 53.0.0
  • Visual Studio Code version: 1.21.0
  • Operating System version: Windows 10
  • Python version: Python 3.5.3 :: Anaconda custom (64-bit)
  • sphinx version: Sphinx (sphinx-build) 1.6.3
  • A sample of or its important fragments:
extensions = ['sphinx.ext.todo',

templates_path = ['_templates']
source_suffix = '.rst'

Expected behavior
No green squiggly lines, and no warnings about lines being too long.

Actual behavior
Nearly every paragraph and list entry is underlined with a green squiggle. Mousing over those lines shows the doc8 warning [restructuredtext-lint] D001 Line Too Long. The text was fine before doc8 was the linter.

Note: when I opened vscode to edit my reStructuredText documents, I was seeing an error about Python not being able to find doc8.main. That's when I discovered you changed the linter, so I installed doc8.

Perhaps I installed an unsupported version? Just in case, here's the output of installing doc8:

Thank you in advance for any help you can provide.

doc8 checks line length, and recommends the maximum to be 79 characters.

You have several ways to change the behavior.

  • --max-line-length int switch can be used and you can specify a integer value you like instead of 79.
  • --ignore D001 switch can be used to suppress the warning.

Such extra switches can be passed to doc8 by adding restructuredtext.linter.extraArgs to your settings file, such as

    "restructuredtext.linter.extraArgs": [
        "--ignore D001"

Thank you so much for the response. I didn't know about restructuredtext.linter.extraArgs. Where is that documented? I'll give it a try this weekend - unfortunately, I can't try it out sooner.
