JavaScript syntax highlighting

[scg]

I suspect there's an obvious solution to this, but I haven't been able to find it yet.

BBEdit's JavaScript syntax highlighting doesn't seem to pick up newer features ('let', 'for...of', template literals, etc.). I thought there might be a language module available somewhere for this (e.g. an ES6/ECMAScript 2015 module), but I haven't found anything.

Is there a way to get BBEdit to include these features in its syntax highlighting? (I'm currently using the free version, although I'm still in the trial period, so I think all features should be available.)

Thanks.

One way to do this (which is what I did): in ~/Library/Application Support/BBEdit/Custom Keywords  (create the directory if it doesn't exist), put a new file with file extension .js in which you put any keywords that are currently lacking, each on its own line. For example, I have a file called JavaScript.js with as its contents

let
of
ObjectId
Enter code here...

but you could put in other ES6 keywords.

Thank you! That worked perfectly. Presumably template literals can't be addressed that way, but I guess one would probably have to dig deeper for something like that (e.g. by creating a custom language module).

Thanks, Jim. This works fine with JavaScript. However, I have had no success with PicoLisp (.l) and Dart (.dart). I tried to install the AutoLISP language module; that gave me highlighting of some Lisp words, but the extra words I had put into my words.l file in the Custom Keywords directory had no effect.

I'm a big fan of BBEdit, and I hope that one day there will be syntax support for Dart, and maybe also (Pico)Lisp.

After having had a closer look at the AutoLISP language module, and another one, I understand a little more. If I find the time and inspiration, I may try to write a language module myself. ;-)

Jon,

Did you manage to get anything for Dart?

Thanks.
