Description

Description

It seems the label in signature help parameter information objects is not displayed in the signature help pop-up, thus providing the user no information as to what parameter he is currently specifying the argument to the call for. Only the documentation is listed.

I realize signature help is experimental, but as I'm integrating with it early I thought I might offer some feedback in order to help it stabilize.

Expected Behavior

Both the label and the documentation of the active parameter are displayed and are updated as the user moves between the arguments of the call.

Actual Behavior

Only the documentation of the parameter is displayed.

Versions

  • Atom: 1.23.3
  • Client OS: Linux 64-bit
  • atom-ide-ui: 0.7.2

Research direction
The issue is in the atom ide ui repository, which is archived. The signature help pop up likely resides in a UI component within the 'lib' or 'src' directory. Look for files related to signature help, such as 'signature help view.js' or similar. The problem is that the active parameter's label is not displayed, only documentation. Investigate how the signature help information object is processed and rendered. Check the official LSP specification for the signature help response structure. Since the repository is no longer maintained, consider alternatives or forked versions.
