Lua mode from MELPA hangs Emacs

[immerrr]

Thanks for the report.

I've looked through, it appears that to reproduce that I need to download/install vagrant + travis image of emacs-lisp worker, don't I?

[swsnr]

Uhm no. There is no such thing as a “travis image of emacs lisp work”…

You need install Lua mode from MELPA, and non-interactively run a piece of Emacs Lisp, that inserts file contents into a temporary buffer, and attempts to enable Lua mode, e.g. something like the following:

(with-temp-buffer
  (insert-file-contents "foo" t)
  (lua-mode))

That should freeze after printing prefix key set to "C-c" to standard output, as described in the referenced Flycheck issue.

I did the following:

• created new user so that my configuration doesn't alter environment
• installed carton via wget ... command specified on its github page
• cloned flycheck
• ran make deps
• ran carton exec emacs --no-site-file --no-site-lisp --batch -l tests/testsuite.el -l tests/test-lua/test-lua.el

~/flycheck$ carton exec emacs --no-site-file --no-site-lisp --batch -l tests/testsuite.el -l tests/test-lua/test-lua.el
Running tests on Emacs 24.2.1
prefix key set to "C-c"
~/flycheck$ 

And it ran fine so far. I guess that's the same as you described, locally it runs OK.

You didn't run anything. You have to actually execute the test suite. Take a look at the Makefile to see how.

But as said, you don't need to run the Flycheck test suite. Any kind of Emacs Lisp snippet like the one I sketched up will do.

[immerrr]

Ok, figured that out, I guess:

~/flycheck$ ~/.carton/bin/carton  exec emacs --no-site-file --batch -l tests/testsuite.el --eval '(ert-run-tests-batch-and-exit "lua")'
Running tests on Emacs 24.2.1
prefix key set to "C-c"
Running 1 tests (2013-03-19 16:36:54+0400)
   passed  1/1  checker-lua-missing-quote

Ran 1 tests, 1 results as expected (2013-03-19 16:36:54+0400)

I guess that means you we're unable to re-produce this issue. I'll promise to check again myself ASAP, but please be patient, I've got a lot of other things to do currently.

[swsnr]

I, too, have been unable to re-produce the issue in the latest MELPA packages of Lua mode. I am thus closing this issue. Please excuse the hassle.

Sure, no problem, glad it helped.
