How to use the new `dfx ide` command

Developers Command Line Tools
1

did anyone manage to find out how to use the above mentioned new sub command?from the description it seems like this is a language server but i can’t wrap my head around how to actually use it with vscode for example.

at first i thought if the command is running and you modify the code it’ll show you errors and so on, i also tried typing code in it like an interpreter. no success either :frowning:

i would appreciate if someone could point me to the right direction.

thanks!

I personally run dfx ide

Then I press “ENTER”

And I get this

dp$ dfx ide

The Motoko Language Server returned an error:
Fatal error: exception (Invalid_argument "String.sub / Bytes.sub")

The same error so far

I would also appreciate more info on how to use this functionality as well.

Thanks for looping us in here. Just wanted to let you know we’re in the process of updating error messages and docs to help with this. Stay tuned!

there has just been a new release that states that there is a topic in the documentation for the now called dfx _language-service command!

didn’t really help me though, did anyone make it work? @hansl can you give me a hint? i guess i would need to write a VSCode extension for example? the docs out there show how to write a LS extension, but i don’t get how to make it work with binaries :face_with_monocle: is there a simple way to invoke this with VSCode?

There’s nothing more to say currently. This is an experimental feature

I wrote a little vscode extension!
