Support for Termux

[ayoubelmhamdi]

I am encountering issues when building crates in Termux, as rustup stable-aarch64-linux-android is not fully supported in this environment. I think it would be helpful if distant.nvim could add support for Termux, as this would enable users to easily use remote Rust development features from their Android devices.

Specifically, I have encountered issues.

TERMUX

termux is an android app that emulates Linux functionality. It has a package manager (similar to Debian apt) and many applications. However, it does not have the distant binary in Termux.
Thank you for your consideration.

It looks like there errors stem from termios which is used by termwiz and portable-pty dependencies. There may be other compilation issues as well which aren't detected until we resolve these.

The termwiz and portable-pty dependencies are used to support remote shells. The fastest way to fix this would be to see if we can disable that functionality on the android platform for termux and see if compilation succeeds. If so, we can have a build with that feature disabled, which is possible now that we have a capabilities checklist as part of the API.

[ayoubelmhamdi]

Thank you for the information and for looking into this issue. I understand that the errors with compiling distant in Termux may be related to the termios library used by the termwiz and portable-pty dependencies.

As you suggested, one possible solution would be to disable the remote shell functionality on the Android platform for Termux, which may help resolve the compilation issues. I think this would be a great idea, as it would enable Termux users to use distant and take advantage of its remote file editing features.

If you could provide a build of distant with the remote shell functionality disabled, that would be much appreciated by the Termux community. We are excited about the prospect of using distant on our Android devices, and we believe that this would greatly benefit our development workflows.

[chipsenkbeil]

It looks like someone created and merged a package for you that compiles distant for termux: termux/termux-packages#15610.

I'll make a note of the changes required to get it to compile and incorporate those eventually, but seems like you're unblocked for now.

[ayoubelmhamdi]

you make a great job @chipsenkbeil
