Preserving comment type (block or line) by pretty-printing.

Christian Rinderknecht requested to merge rinderknecht@fix_comments into dev

Motivation and Context


I changed the type Wrap.comment to record the kind of comment (block or line). I also fixed a bug in the pretty-printer of JsLIGO: comments attached to attributes were not printed (there were in CameLIGO).


  • compiler
  • website
  • webide
  • vscode-plugin
  • debugger

Types of changes

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to not work as expected)
  • Performance improvement (non-breaking change that improves performance)
  • None (change with no changelog)


With the last release of LIGO, the pretty-printers of CameLIGO and JsLIGO transformed all comments into block comments. This is a mistake, as block comments can be nested.


  • Changes follow the existing coding style (use dune @fmt to check).
  • Tests for the changes have been added (for bug fixes / feature).
  • Documentation has been updated.
  • Changelog description has been added (if appropriate).
  • Start titles under ## Changelog section with #### (if appropriate).
  • There is no image or uploaded file in changelog
  • Examples in changed behaviour have been added to the changelog (for breaking change / feature).
