There are several questions here on indenting code in visual studio code (How do you format code in Visual Studio Code (VSCode)?), and on indenting OCaml code (How to indent existing OCaml code), but none of the answers work for indenting OCaml code in visual studio code.
I have installed the OCaml Platform visual studio code extension, vscode-ocaml-format (following https://dev.realworldocaml.org/install.html), ocaml-lsp-server (following https://ocaml.org/learn/tutorials/up_and_running.html) using opam, updated and upgraded everything, used eval $(opam env), but this still does not work. I'm a bit at a loss...
It is very hard to answer such questions as we need more debugging input from your side. On the other hand, it is so hard to get it from vscode so it is better just to walk you through the whole process from the very beginning to see where things might go wrong. I would suggest you follow the process for ease of debugging. After you have everything working you can adapt it to your particular setup.
Create a fresh new folder and put some OCaml file into it, let's name it test.ml and let's put into it the following code,
let test = [
"hello"
]
Now create a fresh local opam switch, by issuing in the same folder as the test.ml file the following command, (note the dot at the end of the command, it is required, it will create a local switch for you)
opam switch create .
Next install the required dependencies.
opam install ocamlformat ocamlformat-rpc ocaml-lsp-server
Create the .ocamlformat file in the same folder as the test.ml file. It will tell ocamlformat that you want to be ocamlformatted and you can use this file to setup your preferences.
Make sure that you have installed ocamlplatform for vscode
Now we are ready for the test. Start vscode and open test.ml. It will ask you to select the sandbox. Select the sandbox that corresponds to the folder where you put test.ml (it should be marked as local and have the same name as the folder name, and there will be the full path to it, so it will be easy for you to find it). The code syntax should be highlighted and there should be no error messages from vscode. Finally, hit Ctrl-Shift-I to re-indent your file, it should transform your code to,
let test = [ "hello" ]

In vs code terminal I'm getting first letter of command twice. it's not causing any problem but it's kind of annoys me to watch the wrong command. I'm not writing any letter twice, the first letter of all commands gets repeated automatically.
as you can see there are 2 commands first one ppython first p automatically got repeated even though i wrote python it makes it ppython. and the first p that got repeated won't delete from there even if i spam backspace so many time . the I tried to clear the command till first p and as I'm not able to remove first p from terminal I just wrote ython in front of it. it looks proper now python. but I got a error response as ython is not recognized command. this same happens with other commands too like cd converts to ccd.
Edit : I Re-installed vs code then but that didn't resolved my problem, when I installed it again all my extensions were there already installed then I deleted vs code again then went to the vs code's location there was a folder name .vscode I deleted that then installed vs code again now all the extensions were deleted from vs code but I'm still having the main problem . that doesn't resolved it. and I'm not getting that error while using other terminals like git bash and I'm getting this error only when I open python file's folder not when I open a react app folder or normal js or other language.
I also tried reseting the default setting from setting.json file as one of the answers suggested but that doesn't worked.
It's hard to answer this without knowing your configuration. What plugins have you installed? Try disabling those related to the terminal emulator one by one to see if they're causing any issues.
In doing this, you would naturally restart the terminal emulator as well. If the problem persists, check if you get this erroneous doubling on a terminal emulator outside of VS Code (Terminal or PowerShell).
If nothing works, try reinstalling the interpreter and also VS Code. Especially the latter, if this seems to affect only the terminal emulator within VS Code.
It's really hard to answer your question without knowing your vs code configuration setting.
The easiest way is you can reset your vs code to default
The Steps
Go to View > Command Palette or press Cmd + Shift + P (macOS) or Ctrl + Shift + P (Windows).
Search for open settings json and select Preferences: Open Settings (JSON) which show ups from the result list.
If you’ve been working with VS Code for a while and installed a lot of things and made a lot of changes, you’ll find there’s a lot of stuff in this file:
Delete everything inside the root braces and save the file
Relaunch your VS Code.
(This step is optional) In case you want to not only reset VS Code but also remove all installed extensions:
Delete the ~/.vscode/extensions folder if you’re on a Mac.
Delete the %USERPROFILE%.vscode\extensions folder if you’re using Windows.
having assured myself that julia is enabled and that the linter is too (in vs code settings: Julia › Lint: Run), i get syntax highlighting on my xxx.jl script but no linting at all.
im on the latest vs code + latest julia 1.07 extension + latest macosx.
i did a clean installation of vs code, wiping all old related folders prior to installation (https://stackoverflow.com/a/53839847/11608725)
so julia is the only extension/package installed, no conflicts should be present.
what am i missing?
thanks!
edit/update:
i also found that i can NOT run an open script (via the leftmost button)
a pop-up says
and clicking on open launch.json gives
from which point on im pretty much stuck. googling around, a couple of very similar issues appeared (eg. https://stackoverflow.com/a/61284896/11608725, https://github.com/microsoft/vscode/issues/94725#issuecomment-612062020), but which should presumably have been fixed with vs code 1.44 and i am on 1.49.
perhaps the no-linting is related to this?
Have you tried Julia Formatter 0.3.0 for vs code? This has always worked for me.
similar message "Please first open a folder in order to .." pretty annoyingly appeared, my end, on a different platform [Win] [Visual Studio Code version: 1.56.2], too
meaning : it's likely the workflow/settings logic specific to VS Code, not an os/platform issue as such
all problems solved, my end, simply by
after launching VS Code
via "File" > "Open Folder..." : just do first -- before doing anything else in VS Code and/or with code-files -- open the current/working project folder [ie. the very folder with a ".code-workspace"-file in it for the given project (source file dir) ]
I am studying economics so I have not much experience in programming. I really would like to make Julia work on Visual Studio Code but I've been unsuccessful.
So I downloaded the Julia extension but I don't know how to define the settings. Do I need to create a launch.json file or any other file to make it work?
I think that somebody asked a similar question previously at "How to setup Julia in VS code?"
but the answer didn't really help me.
Thank you all for your help.
First you need to install Julia on your Mac by downloading the julia dmg file from here. This puts an application in the Applications folder.
There are several ways to set things up so julia will run from command line. I used the following:
ln -fs "/Applications/Julia-0.6.app/Contents/Resources/julia/bin/julia" /usr/local/bin/julia
This should work if the name of your application, that you just installed, is julia-0.6.app
After running the above command, you should be able to type Julia on the command line and have it to start.
You can now create a Julia script and place it in the directory you're running from. I created a file named julia_test001.jl It contained the following:
for i in 1:5
print(i, ", ")
end
This is a very short Julia script I wrote for testing.
Now start VScode and install the Julia language support extension. After that has loaded, open the file Julia_test001.jl. Once this file is opened, click the triangle in the upper right corner or open the command palette and select the option: run code. The julia_test001.jl should run and print the result 1,2,3,4,5.
Followed this piece of instruction to create a language extension for .abcd files.
During yeoman generator I used this as a reference.
Everything went well and the new extension was created. Then I open the generated folder as a Visual Studio project and hit F5 to run VS Code with my newly created extension, but nothing gets highlighted as if there is no support for that language.
I have not done any changes to the generated files, but since I am using Ada.plist as a starting point, shouldn't it at least highlight .abcd file as Ada file?
You need package.json file to register the language. It's described in the same document.

I know I can use command "code" to open VS code or file, but I don't know what should I do to make it possible after I install VS code in Ubuntu.Thanks.
Launching from the Command Line
You can launch VS Code from the command line to quickly open a file, folder, or project. Typically, you open VS Code within the context of a folder. We find the best way to do this is to simply type:
code .
Tip: We have instructions for Mac users in our Setup topic that enable you to start VS Code from within a terminal. We add the VS Code executable to the PATH environment variable on Windows and Linux automatically during installation.
Sometimes you will want to open or create a file. If the specified files does not exist, VS Code will create them for you:
code index.html style.css readme.md
Tip: You can have as many file names as you want separated by spaces.

So, there are a couple of solutions for this.
I've linked a video that shows you how to add vscode to $PATH
(which didn't work for me because I couldn't find the "shell:install path" command)
I uninstalled the vscode from my ubuntu and re-installed using sudo snap install --classic code
(This method worked for me)
Tell me which one works for you... and if you have extensions installed to your vscode then i guess you ought to make a backup or something.
