[ESS] ess-local-process-name

[Hüsing, Johannes]

Thanks, Jeremie, for some guidance. I followed your advice but did not install company as use cases for autocompletion can be generated without it.

Starting emacs -Q -l barebones.el evokes an emacs session, which issues the following message:

.emacs.d/elpa/ess-20220225.1523/ess-r-mode.el: Warning: ‘project-roots’ is an obsolete generic function (as of 0.3.0); use ‘project-root’ instead.

Next, M-x R [RET], interactive session starts including executing "set.wd 'startdir'". When I type me[RET], the message "ess-command: Symbol’s function definition is void: ess-local-process-name [2 times]" is issued.

Apologies that I said that the problem occurred on a Windows machine, when it was, in fact, a machine running GNU/Linux. On the PC at the company, that error does not occur, and autocompletion works the tried-and-true Emacs way.

Cheers

Johannes

Hello Johannes,

I'm posting your email, back on the the list.

I also use emacs on Windows at work and I admit that I have never used emacs -Q, there :-).

However I isolate the ess configuration in a separate file, and load it from my .emacs. A quick test would be to rename the .emacs or .emacs.d/init.el file and just have these 5 lines in a .emacs

HTH,
