As the post says, there’s no shortage of ideas for what we can improve :) Expect various fixes and performance improvements short- and medium-term. The main bottleneck remains being tools.analyzer (as it does for e.g. Eastwood) but recently I've been hammocking a safe way to parallelize it. I've done similar parallelization work in a tools.namespace fork so I'd be pretty confident that it will work.

@U45T93RA6 do you have some profiling data for tools.analyzer?

I profile it from time to time with different tools depending on the task at hand Anything specific you're chasing?

If you have flame graph for a big chunk of analysis (like an entire file) it would be nice

Here's the minimally viable snippet for reproducing what refactor-nrepl ultimately does with tools.analyzer (intentionally skipping its caching layer):

(let [your-ns 'clojure.string]
  (time
    (do
      (#'refactor-nrepl.analyzer/build-ast your-ns (ns-aliases your-ns))
      nil)))

build-ast just calls tools.analyzer or is there anything happening in between?

nothing of interest, it offloads to t.ana pretty directly https://github.com/clojure-emacs/refactor-nrepl/blob/a3f9de809b1246101786ec6160df3b8c66585f74/src/refactor_nrepl/analyzer.clj#L74-L93

Cool, I'll try to poke at it later today

Awesome project, congrats fro the awesome work!

Love the clean-ns fix

@U45T93RA6 I have a flame graph and some initial insights if you're curious

Thank you. I need exactly this for my product in the next couple of months!

is there a way to get help for a tool other than knowing in advance what it does? I found out about clj -Ttools list in your announcement. Is there a way to see what other things are available besides list ? Is there a way to print docs for those ? Most CLI tools offer a --help or a man page. I tried some of the things I know

clj -Ttools 
No function found on command line or in :exec-fn
clj -Ttools help
Function not found: clojure.tools.tools.api/help
clj -Ttools --help
Function not found: clojure.tools.tools.api/--help

clj --help 

there is some more work to do on the help side of tools for sure

whre is the best place to raise an issue to track this ?

https://ask.clojure.org is always the best place to raise questions/issues

we do actually have an existing ticket that's near this but it would be helpful to just ask this too

ok, I'll ask this and if I find the ticket include that too

https://clojure.atlassian.net/browse/TDEPS-201 is the one I was thinking of but it's really a different issue so no need to link

@U011NGC5FFY You can get help for -Ttools like this:

(! 649)-> clojure -A:deps -Ttools help/doc
This api provides functions that can be executed from the Clojure tools using -Ttools.

-------------------------
clojure.tools.tools.api/install
([{:keys [as], :as args}])
  Install a tool under a local tool name for later use. On install, the tool is procured, and
  persisted with the tool name for later use.
...
(! 650)-> clojure -A:deps -Ttools help/dir
install
list
remove
show
(! 651)-> clojure -A:deps -Ttools help/doc :fn show
-------------------------
clojure.tools.tools.api/show
([{:keys [tool], :as args}])
  Print info and usage for this :tool.

  Options:
    :tool (required) - tool name to show

  Example:
    clj -Ttools show deps-graph

I have deps-new installed as tools and so I can get help for that:

(! 653)-> clojure -A:deps -Tnew help/doc
The next generation of clj-new. Uses tools.build and
  tools.deps.alpha heavily to provide a simpler 'shim'
  around template processing.

-------------------------
org.corfield.new/app
([opts])
  Exec function to create an application project.

Thansk @U04V70XH6. Hard to remember that. and very hard for new folk who come to clojure and need to use the tools to "gues". I'm more of the my-program --help (or similar) persuasion 🙂

Yeah, I sympathize. I've been immersed in the CLI stuff for long enough that some of the "weird" command-line conventions have become second nature but I know they're not "normal".

I've asked on clojure https://ask.clojure.org/index.php/11590/support-help-for-tools-use-standard-options-clojure-tooling
