Are there existing Iro grammar files somewhere? about iro4cli HOT 3 CLOSED

@skerit Lookbehinds are not permitted in normal Iro because the lowest-common-denominator Javascript regex parsers do not support them. However, there is no such limitation at the moment for you compiling with lookbehinds using iro4cli, just note that it might break Atom and Rouge compatibility, and there's no guarantee of them working with certain regex parsers.

The file will likely be generated fine, it might just not work in some contexts.
I will add a warning in iro4cli that lets you know that lookbehinds are not fully supported in Iro. 😃

Also sorry, I don't have any detailed examples of Iro grammar files on hand, but I can point you to the file I used in my toy language a while ago, which you can find here. Not exactly complex I know, sorry. 😅

I decided to give it another go and create an HTML Iro syntax from scratch, and to not focus too much on how Sublime or existing tmlanguage files implement it.

It's still a WIP, but I'm getting there.

Ah, unfortunately Iro does not support lookbehinds... So even though parsing HTML is doable, JavaScript is not because you need lookbehinds for literal regular expressions.
