Emacs version

Operating system

This is probably something really stupid and simple, but my google-fu is failing. I'm also a LISP/Clojure/Emacs noob, so apologies in advance.

Vanilla Emacs, installed latest packages through Emacs' package manager. Nothing crazy.

CIDER is attempting to call sesman-linked-sessions which doesn't exist in Sesman, seems like it was replaced by sesman--linked-sessions which should be ok since the new function is aliasing the old one here - https://github.com/vspinu/sesman/blob/14475d8192a785568a23f274f7715b1509da93ea/sesman.el#L976

Yet for whatever reason that alias isn't working on my machine. I changed the function call to sesman--linked-sessions in cider.el and voila - cider-jack-in works!

The fact that the alias isn't working and me being the first to discover this leads me to believe it's not a real bug but something silly I'm just not seeing on my end.

I am not able to reproduce this, with latest CIDER from MELPA.

[mallt]

I think upgrading to the latest sesman version from MELPA should fix this.

[kinleyd]

I can reproduce this error with sesman v. 0.3.2. I've had to revert to git tag v.0.3 to regain cider functionality.

Edit: emacs 26.1-2, cider 0.18.0

[dvelitchkov]

Phew. Glad I'm not the only one. Out of curiosity - shouldn't the define-obsolete-function-alias call in Sesman prevent this from happening? General ELISP question perhaps.

[kinleyd]

There was an issue at the sesman repo which says that the issue was resolved and that we'd just have to wait till the update reaches Melpa. However, that was 4 days ago and the issue remains - could the update take that long to reach Melpa?

[vspinu]

Both cider and sesman are up to date in MELPA. You must be using an older version locally. New cider doesn't use sesman-linked-sessions anymore.

[JMacLulich]

Same issue for me as well after just updating cider.

Will try updating sesman to latest in MELPA

[JMacLulich]

FYI: Updating sesman to latest in MELP fixed this particular problem.

[kinleyd]

Ah yes, just checked my init.el - I'm on Melpa Stable, having left Melpa some years ago. So I'll just wait till the fix percolates there. In the meantime I'm just using a workaround mentioned on Reddit.

[vspinu]

Arh, this makes sense. I have just pushed a new version tag to sesman to avoid issues with melpa stable.

[kinleyd]

Thanks Vitalie, much appreciated!

Edit: The update landed on Melpa Stable and all is good again. Thank you!
