MacVim freezes on quitting/INSERT mode about vimerl

[evnu]

I encounter similar problems sometimes. Can you check if you also see a beam.smp process taking up 100% of one core? This is reproducable on my machine (ArchLinux, Erlang R16B) when I run

erlc erlang_indent.erl

The compilation takes multiple minutes (~2 min. here), which could be the cause of a freezing vim.

[pmichna]

This compilation is fast: ~1 sec. However, I get an error and a bunch of warnings. What to do about that?

[evnu]

My bad, to make it compilable you have to add -module(nameofthefile). to the beginning and delete the shebang #.

[pmichna]

Do you mean to add -module(erlang_indent). to erlang_indent.erl in the 1st line? Doing so in the 3rd line haven't helped as well. I removed the # from the shebang arguments and still nothing.

The beginning of erlang_indent.erl:

-module(erlang_indent).
#!/usr/bin/env escript
%%! -detached

-mode(compile).

[evnu]

The beginning of the file should look similar to this:

-module(erlang_indent).
%%! -detached

-mode(compile).

The warnings on unused functions are ok (there is no -export([...]).).

[pmichna]

Now I get two syntax errors:

erlang_indent.erl:338: syntax error before: '.'
erlang_indent.erl:499: syntax error before: 

I guess in line 338 I have to delete #!/usr/bin/env escript but what about the line 499?

495 parse_tokens(Tokens = [{'-', _} | _]) ->
496         parse_attribute(Tokens, #state{});
497 parse_tokens(Tokens = [{atom, _, _} | _]) ->
498         parse_function(Tokens, #state{});
499 parse_tokens(Tokens = [{T, _} | _])
EOF

[evnu]

The file is only ~340 lines long here. Are you sure that 1. you are looking at the correct file indent/erlang_indent.erl and 2. you are using this repository?

[pmichna]

I just did git clone git://github.com/jimenezrick/vimerl.git and [...]/vimerl/indent/erlang_indent.erl is exactly 499 lines long.

[evnu]

I don't get it..:

335 here. Does wc -l return 499 for you as well? (Anyways, I doubt that we are talking about different files.. I submitted a push request to speed up compilation of said file, maybe you could try if that is working for you?)

[jimenezrick]

It doesn't make sense trying to compile the erlang_indent.erl file, as it is an escript (man escript).

[pmichna]

Ok, now I get 335 lines. However, if I try to install it via vundle, there are 499 lines.

I am trying to compile the erlang_indent.erl with the edits you pointed and, as you said, the process beam.smp is taking ~100% CPU and about 2 minutes. How to fix this?

EDIT: whether it makes sens to compile erlang_indent.erl or not, I still have to wait a long time till the MacVim quits. However, I can switch to INSERT mode now without problems.

[evnu]

@jimenezrick the file is compiled by escript (-mode(compile)). By making it compilable on the command line, one can check if the compiler is taking a very long time to compile it. R15 is fast to compile, R16 takes ages.

[pmichna]

I downgraded to R15B03-1 and it works fine.

[jimenezrick]

It is very strange the file takes so long to be compiled under R16. Did you try removing -mode(compile)? Maybe a compiler bug?

[alan-andrade]

I'm using R16B, vim 7.3 (66), and I'm on a Mac 10.8.4.

My vim and gVim (MacVim) we're hanging after writing -module(demo) . It wouldn't let me write the dot.
The process beam.smp was taking 100% of the cpu and vim was just useless, even after minutes of waiting.

I did what @jimenezrick said, and I commented out the mode(compile). Everything works fine now.

[jimenezrick]

With the release R16B01 the issue should be resolved. The master branch of Vimerl already has the compile directive uncommented so everything should be back to normal.
