error detected while processing function GoFiles about vim-go

[fatih]

Can you past the full log? Usually the file is listed too.

The same issue on OSX (2 errors before opening .go file):

Error detected while processing function GoFiles: line 1: E484: Can't open file /var/folders/2y/xnkn1mdn18j87g40pqc_b3qc0000gn/T/vbAj3PD/0 Press ENTER or type command to continue Error detected while processing function GoFiles: line 1: E484: Can't open file /var/folders/2y/xnkn1mdn18j87g40pqc_b3qc0000gn/T/vbAj3PD/1 Press ENTER or type command to continue

GoFiles() is using go list to obtain the dependencies of the file in your current directory. Do you work on a directory that isn't accessible ? Also can you try to invoki :GoFiles and paste the results there.

[bkaradzic]

Typing :GoFiles produces the same result as above... Empty line, and then can't open file in temp dir.

I'm using FuzzyFinder with VIM, and go list in current directory produces:
$ go list can't load package: package .: no buildable Go source files in ...

I usually open vim in GOPATH dir which doesn't contain any .go files anyway.

Here is my VIM setup: https://github.com/bkaradzic/dotvim

[fatih]

Yeah it needs go files. If there is no go files available it does produce an output like this.

[bkaradzic]

GoFiles does it even if I open vim in dir with .go files.

[fatih]

Can you give me your test files please? I need a way to reproduce it :( Is your GOPATH not set maybe ?

[bkaradzic]

I just tried on this, and even when there are .go files it doesn't work: https://github.com/bkaradzic/go-lz4
GOPATH is set.

[bkaradzic]

Btw, I tried this on Windows, Linux and OSX and I get the same behavior everywhere.

[fatih]

Thanks @bkaradzic , I'm looking at it now.

[fatih]

Just tested it with your package (on Mac OS X) and this is what I have:

I have two questions:

1. I think :GoFiles is not executed in the files folder. Can you give me the output of :pwd before you do a :GoFiles ?
2. Can you simply execute this in your folder from Terminal?:

go list -f $'{{range $f := .GoFiles}}{{$.Dir}}/{{$f}}\n{{end}}'

[bkaradzic]

:pwd returns just current directory which is go-lz4...

But the problem might be that I'm not using bash... On Win I just use standard cmd, on OSX and Linux I'm using fish shell (http://fishshell.com/).

[fatih]

Is escaping different in fish shell? How would the command above work for you ?

[bkaradzic]

Fish is not really backwards compatible. I just changed back to bash (chsh -s ) restarted terminal and now :GoFiles works. Is it possible to add option to specify bash executable path?

[fatih]

We can give a specific shell option to system() call in vimscript. That would do the trick.

[bkaradzic]

Just pasting this as info. But probably you don't want to support all shell variations:
ish: Did you mean (COMMAND)? In fish, the '$' character is only used for accessing variables. To learn more about command substitution in fish, type 'help expand-command-substitution'. go list -f $'{{range $f := .GoFiles}}{{$.Dir}}/{{$f}}\n{{end}}'

[bkaradzic]

Cool! This probably would fix Windows too, since I can use bash from msys there.

[fatih]

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=609599 fixes your problem. Seems you need to apply:

if $SHELL =~ 'fish'
  set shell='/bin/sh'
endif

or

set shell='/bin/sh'

[weitzj]

See also: https://github.com/dag/vim-fish

Vim needs a more POSIX compatible shell than fish for certain functionality to work, such as :%!, compressed help pages and many third-party addons. If you use fish as your login shell or launch Vim from fish, you need to set shell to something else in your ~/.vimrc, for example:

if &shell =~# 'fish$'
    set shell=sh
endif

Best do it somewhere at the top, before any addon code is loaded and executed.

Note that this also affects what :sh[ell] launches, so if you care about that you might want to set it to your second best shell instead. If you use Vim in the terminal you could also train yourself to use :st[op] or CTRL-Z instead and then fg in fish to get back to Vim.

@weitzj 👍

Hi all, i have the some problem:

when i try :GoRun or others GoCommand i have this error

My os is Win7, i use gvim7.4 and in my _vimrc i set:

set shell=cmd
set shellcmdflag=/c

i try :echo system("echo hi") and the error is the some:

i can't understand what i wrong...

[markwest1]

This file opening error occurs when gvim is invoked from bash within MINGW64 terminal, but not when it is invoked from Windows explorer or bash within cmd.exe.

Error when invoked from MINGW64 terminal window:

No error when invoked from bash within cmd.exe:

Log:

[philwhln]

I have this set up in .vimrc

if $SHELL =~ 'fish'
  set shell='/bin/sh'
endif

but still hitting issues when trying to save a file

Cannot execute shell '/bin/sh'

[nishanths]

@philwhln Uninstalling and reinstalling vim-go fixed this for me.

I'd love to know if you found the real cause of the issue.
