Working with a remote REPL does not enable cider-mode when opening local files

[behrica]

Expected behavior

Opening a local clj file, while connected to a remote repl, should enable cider mode automatically . And after this the evaluation of code should work and happen on the remote REPL.

Actual behavior

Cider-mode does not get enabled, it stays in clojure-mode only. And therefore the "cider eval" commands are not working.
Typying manually "cider-mode" in the buffer does work and the code evaluation works as expected

Steps to reproduce the problem

1. Open a local project.clj file
2. connect to a remote repl with (cider-connect '(:host "serveo.net" :port 35868 :project-dir "/home/carsten/Dropbox/sources/expertDossier") )
   This establishes the connection and the repl can be used.
3. the current "project.clj" seems to be associated with the repl session, and cider mode is enabled
4. the sesman browser seems to suggest that things are linked:
   CIDER Sessions:

1: sources/expertDossier:serveo.net:35868
linked-to: proj(~/Dropbox/sources/expertDossier/)
objects: cider-repl %s(clj)

5. open a new local clojure file in the same project does NOT enable cider mode.
   (running "cider-mode" by hand does work and enable it and it shows the connection information in the mode line)

My use case could be helped by #2506,
because with it I could use the interactive "cider-connect" instead of my own function.

I am not sure, if this would fix the issue of not enabling cider-mode, as described here.

[mallt]

Just a quick check, is the value of cider-auto-mode set to t in your config?

[behrica]

I did not change it, so I assume yes.

[behrica]

I looked into it in more detail, and it seems to be related to the fact, that I call "cider-connect" non-interactive.

I saw as well that after the remote repl is started, my clojure-mode-hook indeed misses the "cider-mode".

So somehow the non interactive call of "cider-connect" fails to add the cider-mode into the clojure-mode-hooks

[behrica]

I figured out the problem.

The described behavoiur happens only when the active buffer , while I run cider-connect, is not a project file.

When I run the cider-connect, while for example project.clj is open, it works as expected.

This is maybe a bit confusing, I would say

When connecting to a remote repl it is not obvious, why the current active buffer should have any influence... Specially because I need to set the ":project-dir" explicitly.

I would find it rather "normal" that I can connect to a remote repl, without having any file open in emacs.

So my assumption would be that all clojure files in :project-dir are "automatically" associated with the repl

[behrica]

I tried the PR #2506 and it would indeed solve my problem,
and we could therefore close this, once the PR is applied.
