Code is a cross-platform text editor developed by Microsoft, built on the Electron framework. Visual Studio Code is a binary distribution of the MIT-licensed Code - OSS repository, with Microsoft specific customizations and released under a proprietary license. For details on the mixed licensing, see this GitHub comment. There is also a community-driven, MIT-licensed binary release called VSCodium with telemetry disabled by default.

## Installation

The following flavors of Visual Studio Code are available:

- Code - OSS — Official Arch Linux open-source release. Ships a configuration enabling Open VSX.

  https://github.com/microsoft/vscode || code

- Visual Studio Code — Proprietary Microsoft-branded release.

  https://code.visualstudio.com/ || visual-studio-code-binAUR

- VSCodium — Community open-source release. Nullifies telemetry in the source code [1], also ships configuration with Open VSX.

  https://vscodium.com/ || vscodiumAUR

These different flavors are all built from the Code - OSS repository, but with different licensing and default configurations. Notably, only the proprietary builds are permitted to use Microsoft's marketplace and use Microsoft proprietary extensions such as the OmniSharp C# Debugger. The latter is enforced by a handshake mechanism, and cannot be circumvented. For more info on the differences between open source and proprietary "Visual Studio Code" branded builds, consult the Code - OSS GitHub wiki.

### Extensions support

One of Code's main strengths is its flexible API and rich extension ecosystem hosted on the Visual Studio Marketplace. However, the terms of use of the marketplace only permit it to be used with the Microsoft branded releases. As a result, the Code - OSS source does not include a configured marketplace. The open-source releases above add the Open VSIX extension registry, but this does not offer the same breadth of extensions. It is possible to bypass this limitation.

Warning: Though Microsoft has not directly commented on this issue, one can reasonably conclude that non-branded Code builds do not constitute "In-Scope Products and Services" as laid out by the terms of use. In other words, this activity is not permitted by the marketplace. Also see FS#67780.

Known workarounds are:

- manually install the extension from its `.vsix` file, which can be obtained from the Microsoft Visual Studio Code Marketplace;
- ask the maintainer to upload its extension to the Open VSX registry;
- add the Microsoft Visual Studio Code Marketplace by using the one of the following packages relative to the build you are using: code-marketplaceAUR/vscodium-bin-marketplaceAUR/vscodium-marketplaceAUR/code-oss-marketplaceAUR. Those packages install a Pacman hook that patches the file `product.json` as shown in this Github comment after every package update.

Tip: It is useful to enable a keyboard shortcut to reload the IDE when experimenting with changing `product.json`.

## Usage

Run `code` to start the application (or if you are using other releases, run `code-git` for code-gitAUR or `codium` for vscodium-binAUR/vscodiumAUR/vscodium-gitAUR).

If for any reason you wish to launch multiple instances of Visual Studio Code, the `-n` flag can be used.

## Configuration

code stores settings in `~/.config/Code - OSS/User/settings.json`.

visual-studio-code-binAUR stores settings in `~/.config/Code/User/settings.json`.

vscodiumAUR and related packages store their settings in `~/.config/VSCodium/User/settings.json`.

When migrating from Code to Codium (or vice versa), the settings directory can be copied or moved, since they share most of their codebase, the settings are compatible.

### Integrated terminal

View > Integrated Terminal or `Ctrl + `` opens up an integrated terminal. By default, Bash is used with no additional arguments, although this can be changed. `terminal.integrated.shell.linux` sets the default shell to be used and `terminal.integrated.shellArgs.linux` sets the arguments to be passed to the shell.

Example:

    ~/.config/Code/User/settings.json

    "terminal.integrated.shell.linux": "/usr/bin/fish",
    "terminal.integrated.shellArgs.linux": ["-l","-d 3"]

You might face weird prompts after setting the integrated shell arguments with an external terminal. Remove the line to solve the problem or use an external terminal.

### External terminal

If you are using Terminator as default terminal for Arch and you have an error on Visual Studio Code: `Unable to launch debugger worker process (vsdbg) through the terminal. spawn truecolor ENOENT`, you can change the terminal that will be used by Visual Studio to another terminal (e.g. gnome-terminal).

`"terminal.external.linuxExec": "Your alternative terminal"` sets the default terminal to be used for exec debug.

Example:

    ~/.config/Code/User/settings.json

    "terminal.external.linuxExec": "gnome-terminal"

### Running natively under Wayland

Visual Studio code uses Electron, see Wayland#Electron for more information on how to run it natively under Wayland. However, some applications do not use system electron, but bring their own. Such applications will not read the standard Electron flags file.

When using a per-user configuration, both visual-studio-code-binAUR and code read `~/.config/code-flags.conf`. Note that this is specific to these packages, as they use a patched loader script that reads these options.

If using vscodium-binAUR, use the `~/.config/codium-flags.conf` file. If running from terminal, make sure to run it as `codium` (not `vscodium`), otherwise, it will not use native Wayland window.

vscodiumAUR does not load config files (as it does not use a patched loader script).

### Native file dialog

If using KDE, by default VS Codium opens GTK file dialogs. To fix that, set the environment variable `GTK_USE_PORTAL=1`.

## Troubleshooting

### Global menu not working in KDE/Plasma

Visual Studio Code uses DBus to pass the menu to Plasma, try installing libdbusmenu-glib. [2]

### Unable to move items to trash

By default, Electron applications use `gio` to delete files. `kioclient5` is automatically selected instead if Plasma is detected. Different trash implementations can be used by setting the `ELECTRON_TRASH` environment variable.

For example, for deleting files using trash-cli:

    $ ELECTRON_TRASH=trash-cli code

At the time of writing, Electron supports `kioclient5`, `kioclient`, `trash-cli`, `gio` (default) and `gvfs-trash` (deprecated). More info is available at this documentation page.

### Unable to debug C#

If you want to debug C#.NET (using the OmniSharp extension) then you need to install the Microsoft branded release (from the AUR). This is apparently because the .NET Core debugger is only licensed to be used with official Microsoft products - see this github discussion.

When using the open-source package, debugging fails fairly quietly. The debug console will just show the initial message:

    You may only use the Microsoft .NET Core Debugger (vsdbg) with
    Visual Studio Code, Visual Studio or Visual Studio for Mac software
    to help you develop and test your applications.

For debugging with the open-source package netcoredbgAUR can be used. To run it in VS Code, add this configuration to .NET Core launch configuration of the project:

    ./.vscode/launch.json

    "configurations": [
        {
    ...
        "pipeTransport": {
            "pipeCwd": "${workspaceFolder}",
            "pipeProgram": "/usr/bin/bash",
            "pipeArgs": ["-c"],
            "debuggerPath": "/usr/bin/netcoredbg"
        }
    ...

### Unable to open .csproj with OmniSharp server, invalid Microsoft.Common.props location

You have to switch from mono to proper SDK version props.

    /opt/dotnet/sdk/{VERSION}/Sdks/Microsoft.NET.Sdk/Sdk/Sdk.props

    $(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props

Modify import to look like this:

    /opt/dotnet/sdk/{VERSION}/Sdks/Microsoft.NET.Sdk/Sdk/Sdk.props

    /opt/dotnet/sdk/{VERSION}/Current/Microsoft.Common.props

### Error from OmniSharp that MSBuild cannot be located

It is noted in the OmniSharp introduction that Arch Linux users should install the mono-msbuild package. Without it, you might get an error like:

    OmniSharp Log

    [info]: OmniSharp.MSBuild.Discovery.MSBuildLocator
            Registered MSBuild instance: StandAlone 15.0 - "~/.vscode/extensions/ms-vscode.csharp-1.18.0/.omnisharp/1.32.11/omnisharp/msbuild/15.0/Bin"
                MSBuildExtensionsPath = /usr/lib/mono/xbuild
                BypassFrameworkInstallChecks = true
                CscToolPath = ~/.vscode/extensions/ms-vscode.csharp-1.18.0/.omnisharp/1.32.11/omnisharp/msbuild/15.0/Bin/Roslyn
                CscToolExe = csc.exe
                MSBuildToolsPath = ~/.vscode/extensions/ms-vscode.csharp-1.18.0/.omnisharp/1.32.11/omnisharp/msbuild/15.0/Bin
                TargetFrameworkRootPath = /usr/lib/mono/xbuild-frameworks
    System.TypeLoadException: Could not load type of field 'OmniSharp.MSBuild.ProjectManager:_queue' (13) due to: Could not load file or assembly 'System.Threading.Tasks.Dataflow, Version=4.5.24.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.
    ...

You might be able to build anyway (possibly depending whether you have mono installed too).

Omnisharp ships with its own mono version, so, if it is unable to locate the installed one, if you want to tell omnisharp to look for a "global" mono installed in your machine, put this in your settings.json:

    settings.json

    "omnisharp.useGlobalMono:"always"

### Saving with "Retry as Sudo" does not work

This feature does not work in the code package, because Microsoft does not support the way the Arch package is packaged (native instead of bundled Electron). See FS#61516 and the upstream bug report for more information.

The binary release visual-studio-code-binAUR does not have this issue, and the feature works there.

### Keyboard variants or keymappings do not map

As per the wiki on GitHub:

  Switching keyboard layouts under some Linux window managers does not result in a change in the low level X window APIs VS Code uses to read the current keyboard layout. This means that VS Code ends up sometimes reading one of the other configured keyboard layouts and not the current active one. PR welcome...

Per the wiki, there are two possible solutions:

1. make sure `setxkbmap -query` returns as the first keyboard layout the one you want to work with in VS Code.
2. use `"keyboard.dispatch": "keyCode"` in your settings and restart VS Code. This will prevent VS Code from trying to determine your keyboard layout whatsoever.

### Command "..." not found

In the Microsoft branded releases, the `product.json` file lists the extensions that are allowed to use certain proposed APIs accessed by extensions. Code - OSS and VSCodium distributions lack these values, though this does not appear to be due to licensing. Unlike the forced Marketplace enabling, this workaround is endorsed by Microsoft [3].

This issue can be resolved by installing a Pacman hook that patches the file on every package update:

- For code, install code-featuresAUR
- For vscodiumAUR, install vscodium-featuresAUR
- For vscodium-binAUR, install vscodium-bin-featuresAUR

You can also manually add the relevant entries to the `extensionAllowedProposedApi` section in the `product.json` file:

- For code, edit `/usr/lib/code/product.json`
- For vscodiumAUR, edit `/usr/share/vscodium/resources/app/product.json`
- For vscodium-binAUR, edit `/opt/vscodium-bin/resources/app/product.json`

An example of a manual configuration that would make Live Share work is [4]:

    product.json

    ...
      "extensionAllowedProposedApi": [
        "ms-vsliveshare.vsliveshare",
        "ms-vscode.node-debug",
        "ms-vscode.node-debug2"
      ]
    ...

Finally, you can also enable these options using command line flags, as described for the GitHub pull request extension.

#### VS Live Share missing API

Use either the solution above by editing the `product.json`, or open VS Code with:

    $ code --enable-proposed-api ms-vsliveshare.vsliveshare

Also note that for this extension to work, you need to install dependencies listed here [5].

#### Command 'remote-containers.openFolder' not found

Open VS Code enabling remote-containers API as commented in FS#63374:

    $ code-oss --enable-proposed-api ms-vscode-remote.remote-containers

#### Command 'GitHub Pull Requests: Configure Remotes...' resulted in an error (command 'pr.configureRemotes' not found)

Open VS Code with:

    $ code --enable-proposed-api GitHub.vscode-pull-request-github

### Git: ssh_askpass: exec(/usr/lib/ssh/ssh-askpass): No such file or directory

This error is a result of an encrypted ssh-key and inability to use ssh agent, see bug report. The issue can be solved by installing a dialogue provider like SSH keys#x11-ssh-askpass or the alternatives listed there (e.g. ksshaskpass for KDE).

One thing to note is that for ksshaskpass you would either need to link it from `/usr/lib/ssh/ssh-askpass` to get VSCode to find it:

    # ln /usr/bin/ksshaskpass /usr/lib/ssh/ssh-askpass

or set the following environment variables for your shell, see [6]:

    GIT_ASKPASS=ksshaskpass
    SSH_ASKPASS=ksshaskpass
    SSH_ASKPASS_REQUIRE=prefer

To disable VSCode's internal git-askpass, add:

    ~/.config/Code - OSS/User/settings.json

    {
        "git.useIntegratedAskPass": false
    }

### Cutoff characters in integrated Terminal

Characters that are too wide can end up clipping. For example the italic bold text of Deno stack-traces.

This can be avoided by setting "terminal.integrated.rendererType" to "experimentalWebgl".

### Blurry text under Wayland

Visual Studio Code defaults to run under Xwayland, which may cause blurry text if you are using HiDPI screens. To fix this issue, try forcing Electron to run under Wayland—see #Running natively under Wayland.

Alternatively, if your Wayland environment provides the option to run Xwayland applications unscaled, you can circumvent this issue. You may then run Visual Studio Code with the `--force-device-scale-factor=` option to achieve an appropriate scale for your screen.

For example, for a scaling factor of 2:

    $ code --force-device-scale-factor=2

### No such interface“org.freedesktop.Secret.Collection”

See settings-sync#_troubleshooting-keychain-issues

### Authentication with Github failed while using VSCodium

When connecting a Github account, change "vscodium" to "vscode" in the URL as seen in this comment. Then copy the identification token into VSCodium. Should it still fail, install a keyring like gnome-keyring or create a new keyring as mentioned here in the Visual Studio Code docs and here on Github.

### An OS keyring couldn't be identified

On some desktop environments like i3 VSCode fails to detect the keyring. If you are using gnome-keyring, you can the following line to force VSCode to use that keyring:

    ~/.vscode-oss/argv.json

    {
        ...
        "password-store": "gnome",
    }

The example path above is for the official code package. You might have to adjust the `.vscode-oss` directory path depending if you have a different one installed.
