Thanks for the PR @morganholly, I'm not sure I necessarily understand the change. Could you explain it so I can compare it with my own understanding?

[morganholly]

so i noticed it within this code. all of the itInt, valString, callbackBool, etc were highlighted as proc calls, but they’re enums

flag = FlagVariantRef(kind: fkShortAndLong,
                                shortName: shortName,
                                longName: longName,
                                datatype: when T is int64: itInt elif T is float64: itFloat elif T is string: itString elif T is bool: itBool elif T is FuzzyBool: itFuzzyBool,
                                ...

however i think it may block highlighting actual proc calls in an object construction

[morganholly]

i will see if i need to slightly tweak the regex probably to look for an if, when, elif, else, of, etc

[morganholly]

so i didn't work on the regex yet but it doesn't highlight myProc input so i'll have to work on the regex later

[morganholly]

so i did some work on the regex, i have something working correctly in regex101 but vscode doesn't seem to like it so i have to do a bit more to get a good regex for this

[morganholly]

ok i found a workaround for the issue and added the fixed regex in

[morganholly]

it will require fixing merge conflicts at some point so i may do that ahead of time
