Improvements for REPL output pre-processing and locref navigation #2083

vspinu · 2017-08-28T14:23:48Z

Improving on #2043 a bit for navigation. Pass through file metatdata when available from location references and no info from var names could be retrieved. cider-find-file does a good job in those cases.

Who does this improve the code? Seems exactly the same to me.

The difference is that now :file metadata is picked up when first two resolutions fail (those within or). This happens when a var is a protocol method. This was also the original intention btw.

Ah, I see your point now - var might be present, but its branch might return nil. Add some comments as it's somewhat hard to follow the what the assumptions here otherwise.

Yes, I used "var" loosely to refer to the variable at point, which need not correspond to clojure's var. Will add a couple of notes.

What's the purpose of this change?

Improve original regexp. Currently things like ns1.foo.bar(file.clj:123) are highlighted all the way to 123. This change stops them at (.

Originally I thought all those reference have $ in their name, but that's not always the case.

I think it's subjective whether this is better or worse - in such cases I always add a defcustom.

P.S. Mind the commit message style. 😃

It's not subjective. These pseudo links now behave like links in cider stacktrace buffer. Also like links in every other buffer which has a bunch of links in it (occur, grep, compilation etc) behave like that. It's common to click on multiple error references till you get what you want.

Mind the commit message style. 😃

Indeed. The commit messages should ideally always start with a verb.

 ### Bugs Fixed

+* Improve file retrieval when jumping to REPLs location references and Clojure vars cannot be resolved.


How come you can just to something that's not resolved? I guess you made some mistake in the description here. Or this just for the scope of the REPL defs. Frankly I don't remember much this code and I don't have time to dive into it, but I still have to understand what exactly is this supposed to fix.

That code is recent. I added it in #2043 and now I am just improving on it.

I just said what I did there - when locrefs cannot be referenced from variables at point, use file metadata from the locrefs themselves. I can state it more generically "Improve locations lookup by using file metadata when available". Not accurate but conveys the improvement.

AFAIC, this need not be documented at all as being a small and technical fix on a recent change, but knowing how zealous you are on change-logs I added it.

I am piling a bunch of related changes and improvements here. With a bit more doc this time, so should be self explanatory.

Also fixing failing tests to account for recent buttercup changes.

Two notable new features:

cider-preoutput-hook which implements a customizable pipeline of output pre-processing and includes most of our output pre-processing as "middleware".
cider-repl-highlight-spec-keywords pre-output processor which highlights clojure.spec "explain" keywords. Clojure spec explain output is extremely difficult to read.. Make it a bit easy by showing this:

It'd be better to open more PRs. A bunch of unrelated changes in a single PR is hard to review.

- Disallow highlight spilling over () as in ns.foo.bar(file.clj:123)). - Start matching at the beginning of the symbol, not word. Particularly inhibit matching of namespaced keywords (which could be many).

This allows for customization of the modification of the REPL output before it is inserted into the buffer. New functions to be used as part of this hook: - cider-repl-add-locref-help-echo - cider-repl-highlight-current-project
