lsp-treemacs's Issues

Emacs frozens occasionally after call lsp-treemacs-call-hierarchy

I experience this issue occasionally. After I call lsp-treemacs-call-hierarchy to try to check the call hierarchy of a method, emacs frozons immediately. When this issue occur, the emacs cpu usage increases to 15% and emacs keeps frozon. I have kill emacs manually. My emacs version is 26.1 the version with the debian 10. Thanks!

symbol order reshuffles on focus changes

For example focus changes causes the list of symbols to be reordered, but also navigating around in the source code. It would be nice to have it sorted alphabetically.

lsp-treemacs window selection

How do I select LSP symbol list or LSP error list using the keyboard? Treemacs do provide treemacs-select-window. Is there an equivalent function I can use with respect LSP treemacs?

Symbol’s function definition is void: make-treemacs-theme

Whenever I use lsp-treemacs, or lsp-mode for a scala buffer, I get this error:
Symbol’s function definition is void: make-treemacs-theme.
After disabling dap-mode and lsp-treemacs, I get this one trying to use lsp-mode:
File mode specification error: (void-function make-treemacs-theme)
lsp-treemacs version 20200811.1646. lsp-mode: 20200812.1516. treemacs: 20200802.819.

[Feature]Implement tree view representation of search results(references/workspace symbols/etc)

lsp-treemacs-symbols shouldn't break as code is being edited

I am observing that the contents of lsp-treemacs-symbols window often disappears (or parts of it disappear) as I am editing the code, I am assuming due to the fact that while I am typing, the code is not always in a syntactically valid state. (gif illustration attached)

If this is what leads to breakage, it would be far less intrusive for lsp-treemacs-symbol to simply keep the last known good set of symbols (maybe with a visual indicator that current state cannot be parsed).

lsp-treemacs-errors-list is very slow

we have to rewrite it to use lsp-treemacs-render as well.

Suggestion: make it possible to filter some items from the lsp-treemacs-symbol list

I use LSP with Haskell Language Server, and the request for workspace/symbols returns also the imports under kind 2 as defined in the LSP standard.

As these imports can be numerous, it gets complex having the lsp-treemacs-symbols panel open all the time as I use to have it under treemacs itself, and it is super verbose and you have to go to that panel and scroll until getting to the actual interesting symbols.

I don't think it would be right to remove the imports directly as they are part of the standard, but I think that it would be nice if a variable could be set that filters out specific SymbolKinds.

In this specific use case, I would like to filter out returned values of SymbolKind == 2.

With some guidance I can try to implement this, although I'm not an expert elisper.

EDIT: a screenshot of how it looks like on my machine:

Automatic pop-up / collapse when not needed.

Any plans to add a "collapse when there's no errors around" mode to lsp-treemacs? I don't like the fact that it takes up precious screen real estate all the time.

Actually a better approach would be to make it configurable about when it should pop up. I'd ideally want to make it pop up only if I've been idle for 2 seconds and there's some useful information to show.

Nested project roots not supported

As @yyoncho pointed out in gitter, lsp-treemacs cannot handle nested project roots properly

void symbol, lsp-treemacs-symbols-goto-symbol

I am getting the errors void variable/function on these symbols,

• lap-treemacs-symbols-goto-symbol
• lsp-treemacs-define-action

I think there is something wrong with the last two commits?

[SOLVED] lsp-treemacs not working

I am using doom emacs and I installed lsp-treemacs using M-x Package-install

after running lsp-treemacs-symbols or any other lsp-treemacs app it gives me this error Error processing message (void-function lsp-render-symbol).

There is no `lsp-treemacs-symbols-list` function anymore right?

Hi, I find there is no lsp-treemacs-symbols-list in lsp-treemacs.el, only has lsp-treemacs-symbols.

However, in README, there is lsp-treemacs-symbols-list instead of lsp-treemacs-symbols. I guess lsp-treemacs-symbols-listis replaced by lsp-treemacs-symbols, right?

Thank you.

`lsp-treemacs-symbols`: remember the folding of nodes

lsp-treemacs-symbols allows folding and unfolding nodes. However, after the next refresh cycle, all folding information is lost and the modified nodes go back to their normal, unfolded states. That is especially an issue for dap-mode, where losing variable folding is annoying.

This could be implemented as follows:

• A minor mode could be added, that, for treemacs buffers, records the paths of nodes where the user executed treemacs-TAB-COMMAND into a hash table
• After a treemacs tree is constructed, it is recursively walked and nodes whose paths were stored are expanded. Not-needed and lazily-generated :children would be ignored.

Garbage-collecting the hash-table could be done by recording the last usage cycle for each mapped node, dropping all nodes that were unused for some (configurable) number of cycles. This has the advantage that, for example, deleting a class and undoing that would restore its fold state. When moving a class into a new namespace though, that wouldn't be the case anymore.

I'd like to hear feedback on my approach, and to then implement it in upstream treemacs.

Add option to close lsp-treemacs buffer on RET action

When an option from lsp-treemacs is chosen (for example open references file), it does not close the lsp-treemacs buffer, it just goes to the file and keep the buffer open.
Can we add some configuration/option to enable this behavior?

lsp-treemacs-symbols No symbol-information

I'am new to emacs and I'am studying it . I am trying to use treemacs with typescript ,js files. Treemacs
it works well in the vision of the project but if I ask it to show me the variables and functions of a react class it returns "No symbol information". To see the variables and functions of a react class I use lsp-treemacs-symbols. So before I go to the project using treemacs-switch-workspace and then I do lsp-treemacs-symbols but on every class I go I obtain always No symbol information.
Is there a guide to use tremmacs symbols with react and typescript ?

lsp-treemacs-errors-list: Consider putting errors in the current buffer first

It would be immensely helpful if the current file's errors would be visible first in the errors list; or, only the current file's errors, as an option.

[Feature] synchronize treemacs projects with lsp-mode workspace folders

Possibility to remove the icons

Hi,

I'm using lsp-treemacs and it added icons which I don't use at all in regular treemacs.
How can I remove the icons and not use them?

Thanks!

lsp-treemacs-errors-list position hardcoded to '((side . bottom))

Is there a special reason why this is hard-coded? I have very wide screen and would prefer customizing this to have it on the left or right side instead.

lsp-treemacs can not control new window

Hi,
This should be a feature request.
lsp-treemacs is convenient when writing and debugging code. But if I run a code (python in my case) by ", c c", then the new "complication" buffer is at the bottom of the window and across the whole window.
If I want to maximize my code file buffer, by "SPC w m" it only affect the buffers created by treemacs, the "complication" buffer still there. So I have to switch to "complication" buffer and delete the window.

As running the code happens very often, it is a little noisy. I hope you can add the feature that treemacs can control the "complication" buffer or some other kinds of new buffer that not created by treemacs as well.

`lsp-treemacs-java-deps-list` doesn't work with `lsp-use-plists t`

All packages are recompiled according to instructions about using plists.

lsp-treemacs-error not working properly on windows 10

This issue is the following of #64

On windows 10, with latest lsp-treemacs, the command lsp-treemacs-error-list does return a tree,
but unfolding items return nothing, whereas lsp-ui-flycheck-list does return correctly the errors.

All other lsp-treemacs commands appear to work well

Strange render in lsp-treemacs-symbols

Hello,
I had a weird render when using lsp-treemacs-symbols like as show on the screenshot.

Don't know if it is caused by treemacs or lsp-treemacs. I tried to disable my theme but it didn't change anything.

lsp-treemacs-symbols and autoload

Any reason why this is commented?

;; ;;;###autoload
(defun lsp-treemacs-symbols ()

Please consider making a melpa-stable release compatible with lsp-mode 6.3.1

The latest lsp-treemacs commits seem to break compatibility with lsp-mode 6.3.1 version:
bf05453
90754e4

I am only a light lsp-treemacs user so I did not notice the above immediately, but then came along 5d3f7b4, at which point package load broke, presumably due to lsp-defun being unavailable.

Maybe tagging last-compatible-with-6.3.1 commit to melpa-stable would be a good idea?

Thanks,

(lsp-treemacs-errors-list) and (lsp-treemacs-java-deps-list) commands displays a blank buffer

** Describe the bug **

(lsp-treemacs-errors-list) and (lsp-treemacs-java-deps-list) commands displays
a blank buffer inside LSP Error List.
Sometimes it shows a message that there is an error in calling the command :

---------------------------------------
It looks like you are trying to run treemacs. Would you like some help with that?
You have called treemacs-mode, but that is just the major mode for treemacs'
buffers, it is not meant to be used manually.

Instead you should call a function like
* treemacs,
* treemacs-select-window, or
* treemacs-add-and-display-current-project

You can safely delete this buffer.
---------------------------------------

** To Reproduce **
using treemacs package treemacs-20191205.557 will produce the above errors
but the old treemacs package will not produce the above erros.
like using treemacs package treemacs-20191121.626 will not produce the above errors

** Expected behavior **
I think the lsp-treemacs should be updated.
because it uses the old version of the treemacs package

lsp-treemacs-errors-list shows nothing in C++/clangd

The screenshot of Java errors looks great; I'd love to see the same thing for my C++ code but the "LSP Errors View" window never shows anything - it is empty, regardless of how many errors I inject into source code. flymake displays them... treemacs does not.

I could not find any documentation explaining how to configure this, but I did run (lsp-treemacs-sync-mode 1) before lsp-treemacs-errors-list

Error list is empty, but error and warning count are correct

Thank you for this extension, I am very excited to use it!

See my issue above. This could be a problem with my configuration but I'm not really sure where to look. I've simply enabled lsp-treemacs using use-package, as directed:

(use-package lsp-treemacs :commands lsp-treemacs-errors-list)

I see the correct warning / error count, just not the actual files and errors. Please advise how to debug the issue.

Edit:
Some info: It is a Rust project. I am using treemacs, projectile, lsp-mode, and flycheck, not flymake

Use of theme Iconless raises error when trying to expand top-level entry in errors view

If I set the lsp-treemacs-theme to new theme Iconless, pressing the tab key on the top-level entry of the LSP Errors View results in a Wrong type argument: char-or-string-p, nil and the entry is not expanded. The stack trace shows the following:

Debugger entered--Lisp error: (wrong-type-argument char-or-string-p nil)
  treemacs--do-expand-lsp-projects(#<marker (moves after insertion) at 13 in *LSP Error List*>)
  treemacs-expand-lsp-projects(nil)
  treemacs-TAB-action(nil)
  funcall-interactively(treemacs-TAB-action nil)
  call-interactively(treemacs-TAB-action nil nil)
  command-execute(treemacs-TAB-action)

If I set the theme back to Default again (via Erase Customization), kill the LSP Errors View and display the view again, I get the same error. If I then restart Emacs, still using theme Default, display the LSP Errors View again and press the tab key on the top-level entry, no error is raised and the entry is expanded.

I tested this in Spacemacs develop branch, commit c4ad14a, dated Sunday December 20 2020, using a Python file and the pyls backend.

Is there any possible to show function signature rather than just function name in lsp-treemacs, or provide an option to control it? I found the signature is more easily to distinguish than only a name.

lsp-treemacs-error-list returns nothing

Hello,

If I intentionally introduce some syntax errors in my java source, the language server detects
them instantly and I find them correctly reported in lsp-ui-flycheck-list buffer.

However, nothing shows up with lsp-treemacs-error-list and no errors seem to occur.

Other lsp-treemacs commands, like lsp-treemacs-symbols, work well.

My system is windows 10, emacs 27.1 run under mingw64 with all lsp packages and dependencies updated right now.

Apply all quick-fixes?

lsp-treemacs-quick-fix is very nice. Would be even more convenient to apply all quick fixes from the code buffer without having to open the lsp-treemacs-errors-list and step through each error - is this possible?

Thank you!

Second definition of lsp-treemacs--symbol-icon

Did you mean to redefine lsp-treemacs--symbol-icon in lsp-treemacs.el?

The second defun does not display icons for me, but the first one works fine (at least, it displays the icons properly, but indentation seems to be lacking for child nodes... not sure if this is related).

icon issues with doom themes

original issue: doomemacs/themes#500

looks like this:

should look like this:

the problem is not present until lsp-mode is enabled.

note: the discussion here picks up where we left off in what turned out to be an unrelated lsp-treemacs issue: #66

lsp-treemacs-symbols starts a new timer on each invocation

After you have called M-x lsp-treemacs-symbols say 10 times, lsp-treemacs--update is called 10 times every second, which can cause emacs ui itself to freeze.

[feature] Create imenu like view

Errors list always warns about two errors but never shows them

This is what I always see on my modeline/when opening lsp-treemacs-error-list. It never shows any errors if I purposefully make them and still shows this empty view if there's no issues.

Also, when I select the folder, for whatever reason it opens dired.

If it matters, I'm using DOOM emacs with java & jdtls.

Make `lsp-treemacs-symbols` close the window if it's already opened

This would be consistent with upstream's treemacs function.

(I'm discovering the treemacs as well as lsp parts of emacs, and they all look great! just have a few weirdnesses to hammer out and… :))

lsp-treemacs-references window's treemacs-quit to delete-window

the reference window's key binding `q', which is treemacs-quit, just bury the buffer not killing the window, inconsistent with other window like symbols, and somewhat annoying. is there an option or how can I do it?

reference nodes auto expand

the lsp-treemacs-references window opened with nodes collapsed, but I need it auto expanded. is there an option?

60 character limitation in function definition strings causing confusing truncation

Is it currently possible to set the max width of fn def strings? When I expand, fn defs using lsp-treemacs, they are limited to a max of 60 characters. This leads to confusion and cripples the ability to discern full signatures or distinguish between long function names that overrun the limit.

I notice that both lsp-treemacs and lsp-ui-imenu both have this 60 char limitation. Is this a configurable var? Do you know how to set this?

Thanks

Improve theme

1. collapsed and expanded icons are not used. The unicode chars are hard-coded.

2. Support all-the-icons. The images are not displayed correctly on my MacBook. They look too big as the same as in treemacs.
   I made a new theme in
   https://github.com/seagle0128/.emacs.d/blob/master/lisp/init-lsp.el#L157, which is similar in doom-themes-ext-treemacs.
