Clojurians Log v2

For the longest time I didn't have navigation in CLJS code since I'm always too lazy to setup a REPL. But now I have thanks to LSP!

One issue though: when indexing my project it (= lsp-mode?) complains about too many files and then I think it quits. As long as I visit the "other" file, the navigation to the "other" file works. But can't I just tell clojure-lsp to index my own sources without all the other shit it finds "too many to watch" ?

yes you can

this is the file watch system

I tweaked it on lsp-mode for clojure to ignore some dirs/files

but I think you may know more things to hide/ignore 😛

or you could customize it just for you

it may be the target folder it finds "too much", I'm not sure, it doesn't say

it's a regex variable: lsp-file-watch-ignored

you can disable the warning too with: lsp-file-watch-threshold nil

I'd rather find out what the problem is

https://github.com/emacs-lsp/lsp-mode/blob/master/lsp-mode.el#L307-L342

can I see what it is trying to watch?

There is a hack, let me find it Also, the file watch means: watch for changes on this file, doesn't mean that it'll not use LSP on that file

I don't watch these files, I just want LSP to have them analyzed once. This seems to be conflated.

https://github.com/emacs-lsp/lsp-mode/blob/master/lsp-mode.el#L1718 Probably eval: (lsp--directory-files-recursively (file-truename dir) ".*" t)

change dir with your project path

Never mind, I this is getting too complex for me

probably is the target folder

adding something like this for target show work: https://github.com/emacs-lsp/lsp-mode/blob/master/lsp-mode.el#L336

but the target folder was already in that ignore list

https://github.com/emacs-lsp/lsp-mode/blob/e39c4faa9b007215db0587eec93f58a98c550846/lsp-mode.el#L327

oh, indeed

I just want to be able to say: just watch src and src-cljs, ignore all the rest

Hum, still shows me the target folder

somehow it's trying to watch 4000 files, while I have only 500 or so

try this and check what is the result: M-x eval-expression

(lsp--directory-files-recursively (file-truename "/path/to/project") ".*" t)

I tries this with eval-expression, but I get a blurp of errors, this is where I gave up

:thinking_face:

Ah now it somehow works.

Maybe your initial version wasn't working

("/Users/borkdude/dre/DocSearch/app/asco/updates/AM18-Abstracts-LBAs-Final-XML.zip" "/Users/borkdude/dre/DocSearch/app/asco/updates/AM18-Abstracts-PubOnlyAndPresented-Final-XML.zip" "/Users/borkdude/dre/DocSearch/app/asco/updates/CSS18-Abstracts-Final-XML.zip" "/Users/borkdude/dre/DocSearch/app/asco/updates/GI18-Abstracts-for-Atypon.zip" "/Users/borkdude/dre/DocSearch/app/asco/updates/GI19-Abstracts-Final-XML.zip" "/Users/borkdude/dre/DocSearch/app/asco/updates/GU18-Abstracts-Atypon.zip" "/Users/borkdude/dre/DocSearch/app/asco/updates/GU19-Abstracts-Final-XML.zip" "/Users/borkdude/dre/DocSearch/app/asco/updates/IOS18-Abstracts-for-Atypon.zip" "/Users/borkdude/dre/DocSearch/app/asco/updates/IOS19-XML-Final.zip" "/Users/borkdude/dre/DocSearch/app/asco/updates" "/Users/borkdude/dre/DocSearch/app/asco" "/Users/borkdude/dre/DocSearch/app/clinicaltrials/clinicaltrials-sample/.gitignore" ...)

It's watching zip files... and all kinds of directories that aren't source dirs

you could add updates folder to ignored list

AFAIK there is no allow-list 😕

this isn't working for my use case. why aren't the watched dirs inferred from the classpath that clojure-lsp uses?

yeah, sadly those are 2 different things, the LSP client that should say to server what should be watched

Maybe the clojure-lsp server can just ignore things it can't analyze anyway?

or doesn't that help?

Hi all, I am using lsp layer in spacemacs and added clojure-backend ’lsp to clojure variables, I get this error in *clojure-lsp::stderr*:

Error: Invalid or corrupt jarfile /Users/erooijak/.emacs.d/.cache/lsp/clojure/clojure-lsp

Any idea how to fix?

Can I put a .lsp-ignore?

we already do that, we drop things we don't know

https://emacs-lsp.github.io/lsp-mode/page/performance/#ignore-watch-foldersfiles

or maybe maybe lsp-mode can look in .gitignore? I think that should work for me

lsp-file-watch-ignored <<< .gitignore

I think these are valid ideas, but lsp-mode does not support it, you should raise an issue there, or ask here: https://discord.gg/swuxy5AAgT

the gitignore idea seems valid

ok, I might do it later. Have to get on with work now

https://github.com/emacs-lsp/lsp-mode/issues/713#issuecomment-773311067

Hey @erwinrooijakkers, where did you download the clojure-lsp binary? I suggest you download it from the latest release on clojure-lsp

https://github.com/clojure-lsp/clojure-lsp/releases

Not sure from where spaceemacs is downloading

or what version

I made a PR for this that was rejected. A way to specify the source paths. I also ran into this and haven’t used lsp in a while because of it

Yeah, this sucks

@dpsutton Do you still have the issue number / link? I'll make a comment that this is exactly what I want as opposed to "add everything except"

I’ll look it up. One second

@borkdude https://github.com/emacs-lsp/lsp-mode/pull/1829

@dpsutton I don't see it being rejected, it's just stalled on some discussion?

Maybe start with an issue rather than a PR, to verify what is the desired implementation?

the gitignore idea seems valid:

is just that is not that trivial to support all gitignore syntax

maybe git itself can be leveraged to list files that are not ignored?

as in "watch only what is part of my git index"

git ls-tree --full-tree -r --name-only HEAD

this seems like a no-brainer option to me

I don't see a problem, but it'd need lsp-mode depend on git installed for that feature

but I agree it makes sense

yes, it can be an option: lsp-watch-only-git-index or something

I think it's the easiest way to get done indeed

and for mono-repos: only watch the files that are actually part of the project root, not the entire index

e.g. project/.git, project/subproject

yes, would you mind bring these ideas to the discord server?

so we can discuss the possibilities

I'm not on discord a lot

which server is this

#development

@ericdallo I think my classpath isn't properly lsp-analyzed in this project. How can I fix this?

can I set the classpath manually or ..?

it's a boot project and deps.edn project at the same time (one for backend and one for front-end, so it's complicated)

Check project specs: https://clojure-lsp.github.io/clojure-lsp/settings/

but I think it should work

I don't think I see any docs of how to influence the classpath. "it works" -> how can you verify this

I can't navigate to anything I haven't visited before in my editor

e.g. navigation to libs don't work

check /tmp/clojure-lsp.out

it should tell during the initialize if something gone wrong

2021-02-04T14:57:13.936Z MBP2019.local INFO [clojure-lsp.crawler:165] - Paths analyzed, took 3.5609107 secs. Caching for next startups...

That doesn't seem like it really did anything

considering the amount of deps we have

I get a ton of warnings like:

2021-02-04T14:57:13.955Z MBP2019.local ERROR [clojure-lsp.crawler:149] - Cannot find position for: generate-drugbank-nq {:end-row nil, :name-end-col nil, :name-end-row nil, :name-row nil, :ns dre.task.populate, :name generate-drugbank-nq, :filename "/Users/borkdude/dre/DocSearch/app/src/dre/task/populate.clj", :col nil, :name-col nil, :end-col nil, :bucket :var-definitions, :row nil} nil

like hundreds, maybe thousands

I think that may not be the issue though

it doesn't specify what paths it analyzed

yeah, is not the issue

any Error while looking up classpath info error on logs?

https://github.com/clojure-lsp/clojure-lsp/blob/master/src/clojure_lsp/crawler.clj#L34

no. but I don't trust any logic which tries to do this automatically because our build is pretty custom

@borkdude remove .lsp/sqlite.db and restart the project and check the logs

ok

You can configure custom project specs : https://clojure-lsp.github.io/clojure-lsp/settings/

on how to get the classpath

2021-02-04T15:02:04.946Z MBP2019.local INFO [clojure-lsp.crawler:111] - Analyzing 2 paths with clj-kondo with batch size of 1 ...

ah thanks

so go to external deps worked?

I will try

I think I'll make a babashka script to produce the classpath :P

hahah looks helpful

I mean, to append the clojure -Spath and the boot one

oh, for your project only seems ok

but you could have 2 project specs

this is better:

2021-02-04T15:08:00.235Z MBP2019.local INFO [clojure-lsp.crawler:111] - Analyzing 115 paths with clj-kondo with batch size of 3 ...

yep, this should already work: https://github.com/clojure-lsp/clojure-lsp/blob/master/src/clojure_lsp/crawler.clj#L53-L60

those are the default that clojure-lsp try

nice. we have a custom clojure runner which I have to hook in here

our boot stuff is so custom and slow

it first tries to download deps from s3 for a minute

😮

this is something I want to improve on clojure-lsp somehow, getting classpath could be slow, using lein you need to wait some secs

for your case, is way worst 😂

but this is exactly what I wanted, this config, so thanks

This is my final config:

{:project-specs [{:project-path "deps.edn"
                  :classpath-cmd ["./clojure" "-Spath"]}
                 {:project-path "build.boot"
                  :classpath-cmd ["./boot" "show" "--fake-classpath""-Spath"]}]}

does it invoke this every time I visit this project... I hope not?

it caches on sqlite

maybe it can keep a sha of the files ?

I mean, does it also skip the invocation of these commands then?

2021-02-04T15:13:11.168Z MBP2019.local INFO [clojure-lsp.crawler:111] - Analyzing 123 paths with clj-kondo with batch size of 3 ...

and does it deduplicate the paths?

yes, it uses a digest/md5 on the project-file

excellent

Hum, not sure, probably don't deduplicate

oh, we create a set

so it should remove duplicates

excellent, now it can find even things from cljs.core

problems solved!

what is your general gitignore recommendation for .lsp?

.lsp/sql* ?

yep

actually, I use a global gitignore for that

since nubank has hundred of services

ok

and is not everybody that uses clojure-lsp 😢

because I want to commit my config now

this is my config if you wanna copy something: https://github.com/ericdallo/dotfiles/blob/master/.lsp/config.edn

Does lsp-find-definition or find reference works with namespaced keywords? I am thinking about re-frame where I always struggle to navigate to the definition of the event/subscription.

Not yet, that's exactly what I'm WIP right now 🙂

https://github.com/clojure-lsp/clojure-lsp/issues/288

Should be ready by tomorrow

Related: https://clojurians.slack.com/archives/CPABC1H61/p1612348768252400

:bananadance:

You two are my heroes, @borkdude, @ericdallo. There are so many re-frame subs and handlers in my work project, I get dizzy.

Yeah!!!! Thanks a lot :) I was waiting for this for soooo long haha :)

This will be so good. And I think this is something that wasn't available in REPL-based tooling either

Maybe Cursive has something like this? I wouldn't know

hahah thanks, but not sure it will work for re-frame as you expect 😕 since it's pretty common to use something like: (dispatch [:foo/bar ...]) There is no way to know what is the definition of foo/bar, it's not relate to a require or something like this

the support we are adding is for aliased namespaces like:

[my-foo :as foo]

::foo/bar

then we know where is the definition

@ericdallo Actually there will be something like this. The keyword "definition" is already support for clojure.spec.alpha/def

Auto-resolving keywords doesn't make it a "definition"

does clj-kondo provides the :def for those cases?

I think it'd be possible

What I already find a win is that you could do find references and you will get all the occurrences of :foo/bar regardless of alias

on the same namespace, you mean?

clj-kondo provides :def for clojure.spec.alpha/def currently, but hooks will be extended with the possibility of registering your own def'ed keywords

What I personally want is, regardless of :def just have a list of all :foo/bar whether they occurs as ::f/bar or :foo/bar

Hum, we can do that I think, will confirm tonight 🙂

I think I would want the same for find-references, I want the definition in there too and not have to do a separate search, but this might be a bigger change / option

I mean for normal fns

yeah, we'd need to know what is the keyword that defines it

Note that there can be multiple :defs for the same keyword. E.g. (reg-event-fx [::foo]) and (reg-sub [::foo]).

but personally I'm not interested in :def at all, I just want to see them all - good enough for me

I doubt you two will be less of my heroes when I see how this will work. I’m already super boosted in my editing by these amazing tools.

what I think I am trying to say: instead of choosing between find-definition(s?) and find-references, I want both in one overview. maybe that's a third option: find-defs-and-refs

this already works if client provides includeDeclaration on find-references @borkdude 🙂 Calva use with this flag on already

if we make definition work, that will work too

nice. can I put this in my .lsp/config.edn?

yep 😄

how and where? config.edn:

{:include-declaration true}

I don't see it here: https://clojure-lsp.github.io/clojure-lsp/settings/

oh, just realized it's only available via initializationOptions, so only changing the client 😞 we need to make the code check for the config too

it's easy, but need code changes

here: https://github.com/clojure-lsp/clojure-lsp/blob/master/src/clojure_lsp/handlers.clj#L121

@ericdallo it's not clear to me what the alternative to .lsp/config.edn is. > "initializationOptions" where do these go?

and are these merged with config.edn?

yes, they are sent from client, in this case, lsp-mode

https://github.com/emacs-lsp/lsp-mode/blob/master/clients/lsp-clojure.el#L218

so I can set them in elisp?

yes hahah

there is no defcustom for that, but is something that we could change too on lsp-mode

not sure what to do in elisp to be honest

lsp-include-declaration t ?

oh, it won't work, now I remember why I didn't create a config for that

is not something that is configurable, it comes from the references request

and ATM lsp-mode just hard code to false 😕

https://github.com/emacs-lsp/lsp-mode/blob/master/lsp-mode.el#L4597

it'd be necessary just to include a defcustom as the first arg of this function https://github.com/emacs-lsp/lsp-mode/blob/master/lsp-mode.el#L5535 , something like lsp-include-declaration-on-references

yeah, I looked at that code

anyway, I'll bug the other guy on discord

also in lsp-ui for ls-ui users

lsp-ui?

https://emacs-lsp.github.io/lsp-ui/

:catjam:

overall there are a lot of features, bt you can disable all of them, my favorite is the lsp-ui-find-references which shows a window just like vscode for finding references

is lsp-ui a package you have to install?

yep

just like lsp-treemacs lsp-ivy etc

holy crap, I think this is too fancy for me

thanks for another distracting feature!

The box on the right top that shows the docs of every var. It's nice, but also quite distracting, every time you move your cursor there's docstrings

HAHAHAH

yeah, i disable that

Actually almost all users disable that 😅

can I borrow you settings?

it's something that needs to change the default

sure! https://github.com/ericdallo/dotfiles/blob/master/.doom.d/config.el#L189-L195

🙏

Did you test the lens feature?

https://github.com/ericdallo/dotfiles/blob/master/.doom.d/config.el#L176

clojure-lsp shows references code lens 😎

yes, about the number of usages right?

darn, the doc still is on after your config. isn't it this thing you commented out?

;; lsp-ui-doc-enable nil

yeah, that's it

thanks

😴

Yeah, doom-emacs already disable it by default. 👋

Oh, just tested and the find references on a :foo/bar already works as you expect 🙂
