error not formatted as per efm

Question

I have created a mwe plugin to show my problem for fortran ft.

tree ftrial
ftrial
├── autoload
│   └── makes.vim
└── ftplugin
    └── fortran_mk.vim

with

cat ftrial/autoload/makes.vim
" Variables {{{1
let s:Compiler = get(g:, "fortran_compiler", "gfortran")
let s:ObjExt    =   '.o'
let s:ModExt    =   '.mod'
let s:ExeExt    =   ''
let s:VimComp   =   'gfortran'
let s:FCFlags   =  get(g:, "fortran_fcflags",   '-Wall  -O0 -c')
let s:FLFlags   =   get(g:, "fortran_flflags",  '-Wall -O0')
let s:OutputGvim=   'vim'
"}}}1

" Compile current buffer {{{1
function! makes#Fcompile()
  cclose
  update

  let sou = expand("%:p")
  let obj = expand("%:p:r").s:ObjExt
  let s:fortran_comp_success = 0
  setlocal efm=%E%f:%l.%c:,%E%f:%l:,%C,%C%p%*[0123456789^],%ZError:\ %m,%C%.%#

  " Don't process any further if the compilation is up to date
  if filereadable(obj) && (getftime(obj)>getftime(sou))
    let &statusline = "'" . obj . "':is up to date"
    let s:fortran_comp_success=1
    return
  endif

  let makeprg_saved = '"' . &makeprg . '"'
  execute "setlocal makeprg=" . s:Compiler
  let v:statusmsg = ''
  execute "make " . s:FCFlags . " " . sou . " -o " . obj

  " Don't process any further if the compilation was sucessful
  if empty(v:statusmsg)
    let &statusline = "'" . obj . "':Compiled successfully"
    let s:fortran_comp_success=1
    return
  endif

  if v:shell_error !=0
    let &statusline = v:shell_error
  endif
  botright copen
endfunction
"}}}1

and cat ftrial/ftplugin/fortran_mk.vim :

let s:Compiler = get(g:, "fortran_compiler", "gfortran")
let s:ObjExt    =   '.o'
let s:ModExt    =   '.mod'
let s:ExeExt    =   ''
let s:VimComp   =   'gfortran'
let s:FCFlags   =   '-Wall -g -O0 -c'
let s:FLFlags   =   '-Wall -g -O0'
let s:OutputGvim=   'vim'

function! Compile()
  :call makes#Fcompile()
endfunction

with compiling with makeprg and efm set, I am expecting the error should be nicely formatted, but that is not hapenning. Rather I am getting the error as shown in the screenshots

What I am doing wrong here?

A sample hello.f90 with error is:

program hello
   implicit none
   write (*, *) "Hello"+i
   write(*,*) q
end program

Screenshots:

This is what I am getting with :call Compile()

After I press Enter key after I got the last screen, this is what I get:

Update

I have tried to solve this with gvim --clean, dismiss effect of any other plugin, and it shows a new empty buffer. Kindly have a look at this screencast.

Answer 1

Try to change your errorformat to

setlocal efm=%E%f:%l:%c:,%E%f:%l:,%C,%C%p%*[0123456789^],%ZError:\ %m,%C%.%#

the difference is in separator between LINE and COLUMN. You have %l.%c, but looks like it should be %l:%c

1. there are some problems with autocommands we cannot see from your example (but vim error clearly states it)

2. if you do only set efm=..., set makeprg=..., :make you should have errors correctly put into quickfix window.

If you want to suppress output of :make command, use

:silent make

or install vim-dispatch plugin that can do make in background without noise.
