More Info

This is a fork of https://github.com/phindle/error-lens. Changes between this and the original repo should be reflected in the CHANGELOG file.

ErrorLens turbo-charges the language diagnostic features, by making diagnostics stand out more prominently, highlighting the entire line wherever a diagnostic is generated by the language and also prints the diagnostic message(s) in-line at the site of the line of code which is generating the diagnostic.

ErrorLens example

Features

  • Highlight lines containing diagnostics.
  • Append diagnostic descriptions to the end of the line.
  • Show icons in gutter.

Settings

  • errorLens.errorBackground: Background color of the entire line containing error.
  • errorLens.errorForeground: Text color used to highlight lines containing errors.
  • errorLens.errorMessageBackground: Background color of the error message.
  • errorLens.warningBackground: Background color of the entire line containing warning.
  • errorLens.warningForeground: Text color used to highlight lines containing warnings.
  • errorLens.warningMessageBackground: Background color of the warning message.
  • errorLens.infoBackground: Background color of the entire line containing info.
  • errorLens.infoForeground: Text color used to highlight lines containing info.
  • errorLens.infoMessageBackground: Background color of the info message.
  • errorLens.hintBackground: Background color of the entire line containing hint.
  • errorLens.hintForeground: Text color used to highlight lines containing hints.
  • errorLens.hintMessageBackground: Background color of the hint message.
  • errorLens.light: Overwrite any of the above colors (except message) for light themes
  • errorLens.fontSize: Font size of annotations. HACK

When set to true extension clears all decorations at the time when diagnostic changes (but it could cause flickering if the delay is < 500). When set to false - decorations are not cleared and delay applied to clearing decorations also (but that causes messages being on screen even if the problem was solved).
