Sublime freezes when typing "out." in a workflow block.

As description. Only fix I've found is to restart sublime.

I can say, from personal experience, this makes using the plugin very difficult once you encounter it; even clicking on the line with .out will trigger the issue. I suspect this is linked to syntax highlighting for that keyword, which is here:

sublime/Nextflow.sublime-syntax

Line 510 in 0bd5fd3

- match: \.(out)

The \s* match in particular which isn't anchored.

Hi @cjfields, do you have any more info about this issue that you could provide?

1. Version of Sublime Text?
2. Any potentially relevant messages in the ST console (ctrl+`)?
3. Nextflow project structure? or link to repo?

The issue is likely in the Python code for handling showing a popup with info on process/workflow outputs (

sublime/process_popups.py

Lines 356 to 370 in 0bd5fd3

	class NextflowWorkflowProcessCallEventListener(sublime_plugin.EventListener):
	def on_selection_modified_async(self, view: sublime.View):
	"""Show popups for process calls and output channel property access
	When the cursor is navigated over:
	- a process name (entity.name.class.process.nextflow)
	- process out keyword (e.g. FASTQC.out) (keyword.process.out.nextflow)
	- named output channel (e.g. FASTQC.out.html) (variable.channel.process-output-emit.nextflow)
	A popup will be shown with info about the process input/output channels. For named output channels, the accessed output channel will be highlighted.
	"""
	if view.syntax().name != 'Nextflow':
	return
	if len(view.selection) > 1:

)

Hi @cjfields, do you have any more info about this issue that you could provide?

1. Version of Sublime Text?

Sublime Text 4, Build 4189, Mac OS X

2. Any potentially relevant messages in the ST console (ctrl+`)?

Will check and report back (I need to reinstall the package).

3. Nextflow project structure? or link to repo?

I'm working on a branch of a repo converting a workflow from DSL1 to DSL2 (using nf-core skeleton but as a non-nf-core repo). Example line that caused issue:

https://github.com/h3abionet/TADA/blob/4828dbb22d3a89d2a31a5e0ddd43961a61b29827/subworkflows/local/filter_and_trim.nf#L23

EDIT: I should add, I actually set up a fork of this repo and added it as a custom package in the Packages User directory to see if I could sort it out; interestingly enough it seemed to go away for the time being. I will reinstall the original package and move out the fork to try reproducing w/ the console.

Hi @cjfields I think I have it fixed and working better than before.

Thanks for sharing your workflow. It was very helpful for debugging the issue (bad regex 🤦‍♂️). The POOLED_... process was the one crashing my ST.

Let me know if release 1.2.0 fixes the issue. Sorry for crashing your ST with my crappy code haha

Not a problem at all, I'm glad you took the time to fix it!
