Get the Extension from Visual Studio Marketplace
Tested under Linux. Not working for Windows, since sockets are not supported. See Windows.
(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"
"path/to/lsp-wl/init.wls"
,(concat
"--socket="
(number-to-string port)
))))
:major-modes '(wolfram-mode)
:server-id 'lsp-wl
))For windows, emacs does not support socket communications. We can write a small script (in whatever language that supports stdio and TCP) to bridge between stdio and socket. An example js script can be found here: https://gist.github.com/kenkangxgwe/67e7a830848650bf88bbc36f8d3e2af5.
Then the emacs config becomes:
(add-to-list 'lsp-language-id-configuration '(wolfram-mode . "Mathematica"))
(lsp-register-client
(make-lsp-client :language-id 'wolfram
:new-connection (lsp-stdio-connection
'("node"
"/path/to/lsp-wl-stdio-bridge.js"))
:activation-fn (lsp-activate-on "Mathematica")
:major-modes '(wolfram-mode)
:server-id 'lsp-wl
)) eglot intentionally avoids pipe due to the same reason.
Tested only on Linux, but it may work on Windows.
(let ((wlserver (expand-file-name "path/to/lsp-wl/init.wls")))
(when (and (file-exists-p wlserver) (executable-find "wolframscript"))
(with-eval-after-load 'eglot
(add-to-list 'eglot-server-programs
`(wolfram-mode . ("wolframscript" "-f" ,wlserver
"--tcp-server" :autoport))))))Use coc.nvim together with coc-lsp-wl.
To reveal the internal debug and kernel message, change info to debug at
init.wls#L188 or the similar place if you check out another branch.
It reads:
loglevel = ArgumentValue["--log"|"-l", Alternatives @@ LoggingLevels]
// Replace[_Missing -> "debug"];You can see the logging message in the output console of the editor. You may also dump it to a file. Uncomment init.wls#L194 or the similar place in another branch, so it reads:
logstreams = {
OpenWrite[WolframLanguageServer`RootDirectory <> "wlserver.log"],
First @ Streams["stderr"]
};It will be saved to path/to/lsp-wl/wlserver.log.
Mathematica 12.3 & 13.0 are shipped with a new ZeroMQLink paclet version 1.2.0 which was found to have issues with TCP connections.
Please manually upgrade the ZeroMQLink paclet to version 1.2.6 or later:
PacletInstall["ZeroMQLink"]Some versions of Wolfram Engine do not come with symbol usages. Thus all the hovering and completion documentation will be empty with that particular version.
As a workaround, you can copy an existing Usage.m file from Mathematica or another version of Wolfram Engine.
The path is $InstallationDirectory\SystemFiles\Kernel\TextResources\$Language\Usage.m.
The Curry issue has been resolved in 0.2.1. If it still happens, please file an issue.

Currys has been replaced by lambda expressions project-widely.Meanwhile, I figured out thatCurryis not so efficient as the lambda function, so I started to transform them back intoFunction.Mathematica 11.2 doesn't haveCurryfunction, so far, you just need to checkout thedevelopbranch, where I implemented my ownMyCurryfunction.
