Sdk: Switch CLI to a non-system language

[TomasHubelbauer]

How do I make the dotnet CLI be in English when I'm on non-English Windows?

[johnbeisner]

I have changed the language from English to something else on an English OS - however, it's probably the same technique:
In your command shell; set the environmental variable "DOTNET_CLI_UI_LANGUAGE" to "en"

If that doesn't work - try setting "DOTNET_CLI_UI_LANGUAGE" to nothing

Let me know if that works - I'm now curious...

[TomasHubelbauer]

Thank you @johnbeisner, setx DOTNET_CLI_UI_LANGUAGE en seems to have had the desired effect.

FWIW I think this is a bad default and changing language away from English to the system language should be opt-in (dismissable hint to do it is fine though).

[TomasHubelbauer]

Sorry, this did not end up working out after all. I am now receiving CSC : warning CS2038: Nazev jazyka cz je neplatny ('cs' language code in invalid).

In my <project>.AssemblyInfo.cs file I have Czech generated comments. :-( The CLI is in English though…

Really hope there is a straightforward way to just switch everything to English and ignore the system language, because I sometimes have to work on a machine with Home edition which won't allow me to switch languages and this is extremely frustrating.

Change compiler errors language in Visual Studio 2013

I removed cs and cs-CZ directories in the mentioned path and now things are in English!

[TomasHubelbauer]

And it stayed that way for exactly one compiler invocation. Deleted 1029 afterwards to no avail. It's in Czech again.

@TomasHubelbauer How are you invoking the compilation: msbuild or dotnet build?

[TomasHubelbauer]

@nguerrera dotnet watch run

[livarcocc]

Does this repro when you just do dotnet build?

[TomasHubelbauer]

@livarcocc I have just noticed DOTNET_CLI_UI_LANGUAGE remained set to cz, I must have set it only for the PowerShell session when I tried changing it the last time. Aplogies.

This, presumably combined with the fact that I have deleted the resource directories, now made the compiler spit out warning CS2038 about cz language code not being valid (configured cz in DOTNET_CLI_UI_LANGUAGE but the 1029 [Czech] directory is missing).

At this point, the warning is in Czech (?!) but the exception messages thrown during the execution of the program are in English. The obj/Debug/AssemblyInfo.cs generated file still has Czech comments.

So I have set the variable using [Environment]::SetEnvironmentVariable("DOTNET_CLI_UI_LANGUAGE", "en", "User") as opposed to $Env:DOTNET_CLI_UI_LANGUAGE=en I must have used previously, logged out and back in and it finally works and I have almost everything in English. 💯

The obj/Debug/AssemblyInfo.cs generated file still has Czech comments, but the language code warning is gone and exception messages are in English, so I think I will be able to live with that.

Thank you!

I cannot get an english output for dotnet on Linux Ubuntu 19.04 even with DOTNET_CLI_UI_LANGUAGE set.

FWIW I think this is a bad default and changing language away from English to the system language should be opt-in (dismissable hint to do it is fine though).

Yes exactly this, I appreciate the language change but whenever I'm trying to debug I need to be able to get the verbage in English for better results.

Same here on OSX
export DOTNET_CLI_UI_LANGUAGE="en-US" or export DOTNET_CLI_UI_LANGUAGE="en" has no effect.

@KacperBak have you managed to switch to English in macOS?

[stysiok]

@sergeyzwezdin try to switch your mac language to English. It worked for me.

[sergeyzwezdin]

@stysiok well, it will definitely work :-) But I wouldn't like to change OS language only just for that.

[sergeyzwezdin]

For macOS setting export LANG=en_US.UTF-8 in .zshrc helped to switch CLI to English 🎉
