Comments for Brian Schott

Thanks for improving the qdoj page. I think I'll make the page's text a description of the tool and just leave the nice script you added as the formal source for the code. Maybe I can make an AddOn .

Appreciate your help.

This is the syntax/j.vim file I am using. I received it from Mike Manti who said he might update it, but has not. It does not seem to work as can be seen in the snippet below. Can others recommend improvements, please?

You can see in this example that especially the & and &. colors are unpredictable, for example.

The j.vim file has several problems.

syntax match jVerb          /["-~#$%^*+|,{}<>?]\./

This matches every character in the character range "-~ followed by a dot, and identifies that as a verb (later rules override earlier rules). I recommend that "-~ be changed to -"~

syntax match jConjunction   /[.:"@&`]/

This mis-handles . and :

I recommend this be replaced by two rules:

syntax match jConjunction   /["@&`]/
syntax match jConjunction   /\(^\| \)[.:][.:]*/

Also, &.: needs to be handled

syntax match jConjunction   /[&]\.\:/

There may be other issues?

Also, this would have been simpler to isolate if I had found the example file in text format.
