Should cape-file complete tramp file names? #89

Closed LemonBreezes closed 1 year ago

Hi. I remember previously, when using Eshell, I would get completions from Tramp when typing /ssh:. I don't know if they were coming from cape or from pcomplete or company but I'm wondering if cape-file should handle such file names.

Hi! Tramp is intentionally unsupported for file completion since my experience with it has been mixed (error messages, password prompts which interfere with the completion popup etc). cape-file binds non-essential and uses cape--nonessential-table which prevent Tramp from connecting. If non-essential is removed it may work as long as cape--bounds returns correct file name bounds. You can give that a try and experiment. I guess it needs some debugging.

I should add - if it can be made to work reliably, I am not against supporting Tramp in cape-file. In principle it should work given that Eshell completion with Corfu also seems to work with Tramp (maybe you remembered that). But a quick try of disabling non-essential in cape-file resulted in errors like "Remote file error: Forbidden reentrant call of Tramp" and "Tramp failed to connect. If this happens repeatedly, try...".
