Seeing is Believing Integration for Visual Studio Code

This extension integrates seeing_is_believing with Visual Studio Code.

Usage

Available Commands

Seeing is Believing: Mark/Unmark Line(s) for Annotation

If you want to see what a line returns, this is how you mark it to be annotated.

Seeing is Believing: Run

If no lines are marked for annotation, the only change caused by running Seeing is Believing will be the output of stdout/stderr at the bottom of the document. If neither of those streams have any content, there will be no visible change to the document.

Please note the default behavior of only annotating marked lines can be changed. For more information see the Features section.

Seeing is Believing: Clean

Removes all annotations as well as stream output from the bottom of the document.

Options

By default, --xmpfilter-style is enabled all the time. If you would like to disable it when there are no lines marked for annotation, you can change the seeing-is-believing.annotate-all-if-none-are-marked setting to true.

If the seeing_is_believing binary execution has any content in stderr, the "Run" command will terminate without making any changes. This is for safety, but may be overkill or interfere with the extension functioning properly. You can tell the extension to continue if it experiences any errors by setting seeing-is-believing.halt-run-on-error to false.

Requirements

seeing_is_believing is required. You can install it with gem install seeing_is_believing.

Known Issues

seeing_is_believing prior to version 4.0 has a warning when run on Ruby 2.7.0. That error looks like this:

/Users/brandoncc/.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/parser-2.5.3.0/lib/parser/source/tree_rewriter.rb:269: warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
/Users/brandoncc/.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/parser-2.5.3.0/lib/parser/source/tree_rewriter/action.rb:16: warning: The called method `initialize' is defined here

If you experience this, turn off seeing-is-believing.halt-run-on-error and turn on seeing-is-believing.annotate-all-if-none-are-marked. That should allow the extension to function properly, although it will not fix the errors/warnings until seeing_is_believing itself is fixed.

The recommended solution is to upgrade to version 4.0 or higher of the gem, if you are able to.
