Send errors to your quickfix

David · May 1, 2018

If you want to compile the code you’re working with right now, chances are you can do:

:exe 'compiler '. &filetype
:make

and it Just Works. Your code will build/lint/run and you’ll get your errors and output in the quickfix window (:copen to see it). Your errors will be jumpable instead of having to manually navigate to line numbers. This setup should also work with async make plugins like vim-dispatch or AsyncCommand.

Many filetypes won’t work because there’s support for multiple different compilers: C++ could be gcc, msvc, msbuild, etc. However, the :compiler command tab-completes (with ‘wildmenu’), so give it a try!

The command is called :make, but it works build systems aside from make (scons, msbuild, etc) and for directly calling compilers or running any program.

You might not like the ‘makeprg’ it sets, but you’ll probably like the ‘errorformat’ (to parse the output into the quickfix as jumpable errors).

If you’re still not satisfied, try searching github for compiler plugins. Search for compiler filetypename and filter by Vimscript language. Or Click here to open a prefilled advanced search.

I occasionally change the makeprg while keeping the efm:

compiler python
setlocal makeprg=python\ -t\ -3\ %

And I use my autocompiler.vim plugin to make it more likely that ‘makeprg’ and ‘errorformat’ are already set.

Stack Traces

You can even setup an ‘errorformat’ to understand stack traces. I do that for python so runtime errors are put into my quickfix. However, ‘errorformat’ is esoteric so if you can find someone who’s already done it, all the better.

With a proper ‘errorformat’, you can load your log file with cgetfile /path/to/file.log and then :cnext to up the stack trace.

Fallback Plans

If you can’t figure out an errorformat, you can just open your logfile in a buffer and use gF to jump to the file and line under the cursor.

If your stack traces always look like this with no path:

Exception in thread "main" java.lang.RuntimeException: A test exception
  at com.stackify.stacktrace.StackTraceExample.methodB(StackTraceExample.java:13)
  at com.stackify.stacktrace.StackTraceExample.methodA(StackTraceExample.java:9)
  at com.stackify.stacktrace.StackTraceExample.main(StackTraceExample.java:5)

Then you might have to set ‘path’ so vim can figure out where to find StackTraceExample.java.
