A Wolfram Language Server

lsp-wl's Issues

ZeroMQLink exception thrown on init

Just cloned lsp-wl to my Arch Linux system and, after following the paclet instructions, tried to run it.

With Mathematica 12.0 installed, I ran
wolfram -script init.wls
and got the following output:

[INFO  2021-02-01T21:09:06] Initializing Wolfram Language Server
[INFO  2021-02-01T21:09:07] Language server is connecting the client through
socket.

SocketConnect::zmqexception: 
   A ZeroMQLink exception was thrown - Connection refused (code 111)
[ERROR 2021-02-01T21:09:07] Cannot connect to client via socket.

Symbol's value as variable is void: lsp-language-id-configuration.

On Ubuntu 20.04, I try to use lsp-wl in the self compiled git master version of Emacs using the following settings in ~/.emacs.d/init.el according to the notes here:

(add-to-list 'lsp-language-id-configuration '(wolfram-mode . "Mathematica"))

(lsp-register-client
 (make-lsp-client :language-id 'wolfram
                  :new-connection (lsp-tcp-server-command
                                   (lambda (port)
                                     `("wolfram" ;; or "wolframscript"
                                       "-script" ;; or "-file"
                                       "~/Public/repo/github.com/kenkangxgwe/lsp-wl.git/init.wls"
                                       ,(concat
                                         "--socket="
                                         (number-to-string port)
                                         ))))
                  :major-modes '(wolfram-mode)
                  :server-id 'lsp-wl
                  ))

But when I start Emacs, I noticed the following info:

Warning (initialization): An error occurred while loading ‘/home/werner/.emacs.d/init.el’:

Symbol's value as variable is void: lsp-language-id-configuration

Any hints for fixing this problem?

Feature Request: Provide a debugger for vscode

This extension is very good but it needs a debugger to be completed.

Cut down initialization time for debugger (and server)

On Ubuntu 20.04, I use the latest stable vscode and the git master version of lsp-wl. I noticed the following strange problem: after login into the system, the first time running of the "Start Debugging F5" with the lsp-wl will fail with the following error:

The easy and quick way to fix this problem is running the math or mathematica commands once. Other workarounds, based on my observation, including, but may not be limited to, the following way: Click on the "Cancel", and then re-run the "Start Debugging F5" for several times, the problem will finally disappear.

Afterwards, if I close the vscode, then restart it, the problem doesn't appear again. More specifically, the problem occurs only when F5 is called from vscode for the first time after logging into the system.

Feedback for special symbols in `usage` messages

This issue keeps track of the symbols that are not shown correctly in the symbol usage messages (such as hover and completion).

Some symbols are defined in the Private Use Area of Mathematica fonts, thus we are looking for Unicode symbols to replace them.

For example:
\[LeftAssociation] -> <|
\[TwoWayRule] -> <->

TODO:

• ReplacePart::usage: "\[Null]" -> "", fixed in e778be7
• BeginPackage: "`" -> "\`", fixed in 5bb09a4
• Root: "\[Equal]" -> "==", fixed in e778be7

A small article about installing this project.

I installed it several days ago, met several problems. Finally I overcome them, and hope this article can help others.Besides, it is awesome!

https://zhuanlan.zhihu.com/p/88607694

debug doesn't work properly.

I use this code. And into debug mode.

Having trouble running remote server

Hi @Gravifer , did you open a remote file with a local VSCode. If so, can you open a local file with the server running correctly?

Yes, the server is working smoothly on local files.

In the former comment, I was actually trying to link the server with a WolframEngine kernel on the remote machine, by modifying the remote:SSH settings.json, specifying the path of wolfram on the remote machine, as well as the path to the clone of this repo on the remote machine. There are several possible combinations:

	kernel	language server	file	current status
1	local	local	local	neato ditto
2	remote	remote	remote	ZMQ exception
3	local	remote	remote	to try
4	remote	local	remote	to try
5	remote	local	remote	to try

I'll update my testing results here ASAP.

P.S.: At this point it seems that support for remoting could actually be a separate feature request, and may not really fit in the thread of this issue. Feel free to move this discussion to a new open issue if needed.

High CPU usage on start

Hello, I've just started using lsp-wl, and I've discovered that the WolframKernel process is using 100% of one core as soon as VSCode is launched, and pegs it there. I'm running Mathematica 11.3, and the latest pull of lsp-wl.

Unable To Connect to Wolfram Kernel

我Mathematica升级到12.3后我就无法使用lsp的补全功能了，看起来是没有连接到wolfram内核上去

设置都是没问题的，内核我也都确认了没有问题

About Plot in .wls

Recently I find this https://tieba.baidu.com/p/6566049919 8th floor.
And I try it in wls.

<<JavaGraphics`
Plot[x,{x,0,5}]

The picture flash by. So I wonder there maybe some ways to hold it?

PS, if I run it line by line, this is the effect.

PPS, recently I use matlab, and matlab can plot.

this is its code in Code Runner.

"matlab": "cd $dir && matlab -nosplash -nodesktop -r $fileNameWithoutExt"

I tried to use it on mma's setting.

"wolframscript -file"

But failed.

Connection to server got closed. Server will restart.

I'm trying this server with coc-lsp-wl but I'm only getting "Connection to server got closed. Server will restart." in :CocInfo.

Output: https://gist.github.com/oblitum/4e8489a0205ec49650046a005c9f9c7f

lsp doesn't support AST 0.14

recently I often met with this.

then I try to upgrade it.

But it didn't work.

So I asked others,get the reply.

So I make this issue.

after 900s , I update AST successfully.

PacletUpdate["AST", "Site" -> "http://pacletserver.wolfram.com", 
 "UpdateSites" -> True]

Is syntax highlight provided?

I follow the steps in the installation section but found there was no syntax highlighting? Currently, I am using this plugin for syntax highlighting.

Doesn't recognize ##

Slot can be recognized,but ## can't.

My mouse is on the ## , but nothing appear.

Mathematica 12.1 stop working after installing these Paclets....

Hi,
I played with this language server protocol yesterday and following instructions, I ran PacletInstall["CodeParser"]
PacletInstall["CodeInspector"] in my Mathematica 12.1 notebook.

However, my MMA stopped working today. It freezes at the initializing process when I try to open it.

Any advice on undo the language server protocol and these 2 installed paclets, so I can make MMA work again?

PS: I tried to reinstall MMA, but it still doesn't work.

Syntax highlighting missing

First of all, awesome project, thank you!

I have done everything in the docs, but I still don't get syntax highlighting. I have verified that the language server is running. What am I missing?

AST-0.16, Lint-0.16

The language server does not seem to start in my VS Code. It keeps notifying me to install the right AST and Lint version AST-0.15 and Lint-0.15. Running {PacletInstall["AST", "UpdateSites" -> True], PacletInstall["Lint", "UpdateSites" -> True]} returns

{PacletObject[
Association[
  "Name" -> "AST", "Version" -> "0.16", "WolframVersion" -> "11.0+", 
   "Creator" -> "Brenton Bostick <[email protected]>", 
   "Extensions" -> {{
     "Kernel", "Root" -> "Kernel", "Context" -> "AST`"}, {
     "Documentation", "Language" -> "English"}, {"LibraryLink"}}, 
   "Location" -> "C:\\Users\\407\\AppData\\Roaming\\Mathematica\\\

Paclets\\Repository\\Lint-0.16"]]}

Am I doing anything wrong here?

FoldWhile in Server.wl should be renamed to fix name clash with new System` symbol introduced in Mathematica 12.2

Basically, FoldWhile is a new System-context symbol in Mathematica version 12.2 and higher:

So there is a name clash with the function defined in Server.wl. As far as I can tell, the LSP function and the System-context context function do the same thing, but the LSP function should be renamed to fix the issue.

the develop branch seems could be merged to master branch?

as the title said.

The usage of lsp-wl integration with Emacs.

On Ubuntu 20.04, I try to use lsp-wl in the self compiled git master version of Emacs using the following settings in ~/.emacs.d/init.el according to the notes here:

(add-to-list 'lsp-language-id-configuration '(wolfram-mode . "Mathematica"))

(lsp-register-client
 (make-lsp-client :language-id 'wolfram
                  :new-connection (lsp-tcp-server-command
                                   (lambda (port)
                                     `("wolfram" ;; or "wolframscript"
                                       "-script" ;; or "-file"
                                       "~/Public/repo/github.com/kenkangxgwe/lsp-wl.git/init.wls"
                                       ,(concat
                                         "--socket="
                                         (number-to-string port)
                                         ))))
                  :major-modes '(wolfram-mode)
                  :server-id 'lsp-wl
                  ))

After Emacs has been started, I still don't know how to trigger/activate the corresponding functions supplied by lsp-wl, just as seen in vscode shown in the following screenshot:

Any hints will be highly appreciated.

Server constantly eats 30% of cpu core

macOS/MMA 12.2/12.3pre, VSCode. 'development' branch.

This behaviour persist even when VSCode is not visible and nothing happens.

Any hints on how to diagnose this further are welcome.

Cannot handle `contentChanges` in `textDocument/didChange`

To reproduce, use vim-surround and add two brackets around a word

Add `kind` in the 'completion` reponse

Do not wait until completionResolve to reveal the item.kind

This is my current state.

Running test failed

I'm new to VS Code and this extension. I tried to install it and run the test with wolframscript /path/to/lsp-wl/init.wls --test, -t. It returns the following error:

Running tests for all.

FileExistsQ::badfile: The specified argument AST`Library`Private`CompiledLibrary[/Users/User/Library/Mathematica/Paclets/Repository/AST-0.15/LibraryResources/MacOSX-x86-64/expr.dylib] should be a valid string or File.

The extension also does not seem to be started in my VS Code. I have already install the AST and Lint Paclet with {PacletInstall["AST", "UpdateSites" -> True], PacletInstall["Lint", "UpdateSites" -> True]} in Mathematica and it returns {Paclet[AST, 0.15, <>], Paclet[Lint, 0.15, <>]}, which means that the 2 paclets seem to be rightly installed.

Am I doing something wrong here?

STDIN Support with MathLine

It will be helpful to implement a stdio channel, so that the Mathematica earlier than 11.2 will also be supported, but it is really hard to expose the stdin channel. Hope this will be dicussed in future release of Wolfram kernel.

This has been a well-known ( to people that know it) problem with Mathematica for years and is unlikely to change anytime soon. I wrote MathLine specifically to deal with this problem. It may be of help to you.

how to close/ignore the warning?

my AST is version 0.15.1 , which is higher than requirement.

---

I find it in the Server.wl , line 1624

Just change it as follow.

dependencies = {
			{"AST", "0.15.1"},
			{"Lint", "0.15.1"}
		}

I didn't come up with a better method for the time being.

StringDrop::seqs messages

lots of messages like this are generated during textDocument/publishDiagnostics:

StringDrop::seqs:

The different display style for \[Pi] in vscode and MMA.

On Ubuntu 20.04, I test the math symbols display in vscode and MMA respectively with the following example file:

$ cat 11.wl 
\[Pi]*2

In the debug console of vscode with the help of lsp-wl:

In MMA:

Why it can't be displayed as the corresponding math symbol in vscode?

Can't find the real document path.

Reason:

fixed in 2109999

Faile to display some math symbols in debug console and comment out code line/block.

On Ubuntu 20.04, with the latest stable vscode and git master version of lsp-wl, see the following screenshot for more detailed info:

Another problem, I find the "Toggle Code Line/Block Comment" don't work at all.

Any hints for these problems?

Missing dependency

I got following error:

Needs::nocont: Context GitLink` was not created when Needs was evaluated.

This error has resolved by installing GitLink.
This dependency should be written in README.md, I think.

Completion provider, triggerCharacters is not String[] but String

Hi, I am trying to implement a lsp-wl client in emacs (lsp-mode). However, the editor gives an error on completion because the lsp client expects the triggerCharacter to be a String[] instead of String.

I am not a developer, just trying to implement the lsp-client which the lsp-mode author made quite easy to do. However I contacted him about this 'bug' and he mentioned this in his reply (see image below)

it seems that vscode's plugin page could update.

The strange results given by the second complement behaviour of lsp-wl in vscode.

On Ubuntu 20.04, I use lsp-wl with the latest stable version of vscode. I find a strange completion behaviour as described below:

Firstly, we type \ and some character, say, f, as shown below:

Then, we click on Backspace to delete the f, and re-type f. This time, the pop-up window of the completion entries will look like below:

As you can see, they are different. Any hints for this problem?

Regards,
HY

an advice( Inspired by the C++ language plugin)

for example:
When I type Plot ,it will show this.

after that,I want to type, for example : Plot[x,{x,0,5}]
but after I type [] , I have to type the format by memory.
Can it show the hint like this? (though C++ is huge different from mma)

After I type something and a comma , it will change the highlight.

Completion of $Abcdefg gives $$Abcdefg.

[Feature Request] Resolution of namespaces

The current implementation supports document structure based on MMA cell structures (like (* ::Title:: *)). To my knowledge the official version is a pure front-end feature, and it is of much convenience to have it handled for code editors.
However, the kernel features - namespaces (contexts and packages) and scoping constructs like Module Block - are not resolved. Therefore, developers will have to go through the scripts manually to tell which context a symbol is in.

As most authors use namespaces concurrently along with cell structures, the current features are actually sufficient, and this issue may not be a necessity; if this is the case, this thread could be used to discuss the best practice for concurrent use of namespaces and cell structures.

ParentDirectory related messages

There're lots of messages in the form:

ParentDirectory::dirnex: 
   Directory Users/ppavel/Projects/wolfram-engine-app-server/paclet/Kernel/App
     Server does not exist.

ParentDirectory::nums: 
   Argument ParentDirectory[Users/ppavel/Projects/wolfram-engine-app-server/pa
      clet/Kernel/AppServer] should be a positive machine-size integer, a
     nonempty string, or a File specification.

ParentDirectory::nums: 
   Argument ParentDirectory[ParentDirectory[Users/ppavel/Projects/wolfram-engi
       ne-app-server/paclet/Kernel/AppServer]] should be a positive
     machine-size integer, a nonempty string, or a File specification.

ParentDirectory::nums: 
   Argument ParentDirectory[ParentDirectory[ParentDirectory[Users/ppavel/Proje
        cts/wolfram-engine-app-server/paclet/Kernel/AppServer]]] should be a
     positive machine-size integer, a nonempty string, or a File
     specification.

General::stop: Further output of ParentDirectory::nums
     will be suppressed during this calculation.

support for unicode

as the image shows, it will warning. But it did can run in .wls.

\[Alpha]=1
Print[\[Alpha]]

besides, I have tested that this can't run.

α=1;Print[α]

in .nb , α will be translated into \[Alpha] ,then do the following calculation.(But shown as α).

So here are some advice.

1. in vs code, show \[Alpha] as α,but run it as itself.(But it's confusing that how to deal with the widith of this character)
2. if users copy it to clipboard, automatically change it into α.But if use //CopyToClipboard//UsingFrontEnd,it's also hard to deal with.(Or maybe just ignore it?)
3. if someone paste α into vscode, change it into \[Alpha] (but shown as α)

Maybe there can be a switch to open/close the "translate"? If some users really want to see \[Alpha].

Collecting possible formatting styles

This issue is to collect different formatting styles of Wolfram Language. The current state of the language server is not capable to do complicate formatting (not even simple ones, because I haven't implemented any lol). I know that Brenton (@bostick the author of AST and Lint) is working on a code formatter (see the end of the video, and I definitely admire his ambition to do notebook manipulation 🤣 but I haven't known whether his formatter will let users define their own styles.

Since people have different appetites this issue welcomes ALL possible styles that we can format the wolfram language into. YES, all possible styles. I didn't say I would accept or implement all of them, just for the aesthetic purpose.

A code block or screenshot to illustrate the style is recommended.

Here are some features we can start thinking from:

indentation

• indentation character: Tab vs
• indetation width
  • constant integer: 2, 4, etc.
  • adjust it according to context
    • Align it with other parameters in the function call

      If[condition,
          true,
          false
      ]

whitespaces

• whitespaces for between operators:
  • F@a vs F @ a same for (//)
  • a ~Join~ b vs a ~ Join ~ b
  • i++ vs i ++ same for other unary operators
  • "str"<>"ing" vs "str" <> "ing" (same for ~~)

empty lines

• top-level expressions
  Adding two lines will make a separate cell for the code block if you open the
  .wl/.wls file in Mathematica. Thus it is recommended to split up different
  Functions into cells.

  (* ::Section:: *)
  (*section name*)
  
  
  Function1 := functionDefinition1
  
  
  Attributes[Function] = {Protect}
  (* overloads *)
  Function2[a_String] := (functionDefinition2)
  Function2[a_] := (functionDefinition3)

  vs keep it as it is

line wrapping

• Wrap a long line (exceeds 80 chars for example)
  first parameter dangling if it doesn't exceeds 80 chars after wrapping

  Function[aVeryLongParameterThatSomeHowYouWantToWrapTheLine1,

Dangling WolframKernel instances

Using it with coc-lsp-wl, when I close Vim, the WolframKernel instance started by the editor is left dangling when the editor is closed. Does the plugin have to do something in particular to close it? The WolframKernel instances keep accumulating and the fix I know of is to killall -9.

how to format MMA code?

As far as I know. MMA doesn't have a commonly used code formater.

I searched on mse, find this https://github.com/lshifr/CodeFormatter . But it seems a bit hard to use.

So where can I find the code formater?(Since there are only 3 mma-about plugins in VS Code plugin market)

Meanwhile, format it by hand is not pleased.

[UnexpectedCharacter] Unexpected character: "\:0438".

Good day!

I'v got lots of messages like this (the character is a Cyrillic unicode character as encoded by MMA in notebooks AND .wl files created using frontend).

P.S.:
I'm willing to participate in development of the project. Frankly I tried it several times with VSCode but it never even started wolfram kernel. This issue should be broken in parts probably so please consider is as an initial contact.

Currently the server starts but the only thing that works is getting document outline from the server (no syntax highlighting, no hover info etc). This behaviour persists in both master (that seems to be "more broken") and development branches.

I get both 12.2 and 12.3 prerelease versions installed under macOS and I also use Linux so I can try different combinations.
