I'm using GVim 8.1 on Windows 10 with no external plugins.
I have the following set up in my .gvimrc file:
let g:build_file_abs_path = fnamemodify(findfile("windows-build.bat", ";."), ":p:h")
" This build script is a basic wrapper for 'clang.exe file.c -o file.exe' style invocation
let &makeprg=g:build_file_abs_path . "\\windows-build.bat"
nnoremap <silent> <C-B> :cd <C-R>=g:build_file_abs_path<CR> <bar> make! <bar> copen <bar> redraw <bar> cd -<CR>
Now, this automatically opens a quickfix window with the correct compiler output. However, when I press ENTER over the error, the cursor jumps to the buffer for the affected file, yet it is completely blank with a single line. Furthermore, this occurs as I use :cn and :cp commands inside the quickfix window. e.g:
Images showing these two states:
before
after
Please note that:
:verbose nmap <CR> returns no mappings, so there is not conflict there.
I would appreciate it if someone could provide some insight as to how to avoid the buffer becoming empty and actually jump to the error in the appropriate file. Many thanks.
Thanks to Christian Brabandt's comment, I was able to solve the issue. I was misunderstanding the distinction between the working directories of vim and the build script. I made the following changes:
let &makeprg="cd " . g:build_file_abs_path . " && windows-build.bat"
nnoremap <silent> <C-B> :make! <bar> copen <bar> redraw <CR>

I manually replace ^M with
:%s/<ctrl-v><ctrl-m>//g after I open a log file. I have to do this several times a day so I tried to assign F11 key to perform this action.
I tried the following in .vimrc but it did not work.
:nnoremap <silent> <F11> :let _s=#/ <Bar> :%s/^M//e <Bar> :let #/=_s <Bar> :nohl <Bar> :unlet _s <CR>
Note: I pressed ctrl+vctrl+m to get ^M in the above statement.
I have a similar assignment for F10 to remove EOL whitespace and that works.
:nnoremap <silent> <F10> :let _s=#/ <Bar> :%s/\s\+$//e <Bar> :let #/=_s <Bar> :nohl <Bar> :unlet _s <CR>
What am I doing wrong here?
Check that your terminal actually forwards F11 to the commands it’s running instead of listening to the key itself. For instance, the default configuration of Windows Terminal intercepts F11 and does not forward it, so you can’t rebind the key inside Vim.
Furthermore, your command looks quite convoluted; my Vimscript knowledge is limited but if the purpose of your command is to change Windows file endings into UNIX file endings, the following, simpler command works:
:nnoremap <silent> <F11> :set fileformat=unix<CR>
There’s also a widely installed utility program, dos2unix, that does the same, and which might be even simpler for your use-case.
Is there a way to search the list of recently used file in Vim? The list can be displayed using
browse old
but / does not work. I am aware of some plugins (e.g. MRU) but would prefer to not use a plugin.
Here's a short scriptlet that opens the file list in a scratch buffer. As a bonus, it defines a local <Enter> mapping to :edit the current file. With this, you can search with all built-in commands like /:
:new +setl\ buftype=nofile | 0put =v:oldfiles | nnoremap <buffer> <CR> :e <C-r>=getline('.')<CR><CR>
If you really want to avoid a plugin:
:new The old files will be printed into this buffer
:redir #X where X is a temporary register`
:silent echo(v:oldfiles) 'Silent' is there to not actually print onto your screen
:redir END
"Xp paste the temporary register
(optional) Do some regex-fu to put each file on its own line.
Put the above into a function and voila. Also :help redir
It's actually not very hard to write a simple (simplistic?) MRU command with completion that works like :edit or :split:
" this is our 'main' function: it couldn't be simpler
function! MRU(arg)
execute 'edit ' . a:arg
endfunction
" the completion function, again it's very simple
function! MRUComplete(ArgLead, CmdLine, CursorPos)
return filter(copy(v:oldfiles), 'v:val =~ a:ArgLead')
endfunction
" the actual command
" it accepts only one argument
" it's set to use the function above for completion
command! -nargs=1 -complete=customlist,MRUComplete MRU call MRU(<f-args>)
Here is a .vimrc version of code above. Just add following lines to .vimrc and map to desired keys (in my case it is 'o). In addition define patterns to remove "junk" files. Also cursor is placed at the top for convenience.
Most hard thing is to map an Enter inside nested nmap. ^V is the result of doubled Ctrl-V. ^R is the result of Ctrl-V+Ctrl-R. ^M is the result of Ctrl-V+Enter. You need manually repeat those symbols - not just Copy/Paste. Spent hours to understand this magic - so I'm glad to share. This technology lets you add own macroses in .vimrc.
" Browse Old Files
nnoremap <silent> 'o :enew<CR>:set buftype=nofile<CR>:set nobuflisted<CR>:exe "0put =v:oldfiles"<CR>:nmap <buffer> ^V^V^M :e ^V^V^R=getline('.')^V^V^M^V^V^M<CR>:g/\v(stdout\|nerd\|fugitive)/d<CR>:0<CR>
This is my take on Ingo's answer above for my .vimrc:
Opens the old files in either a vertical split or tab, then maps enter to open file under cursor! magic!
" open old files list and map enter to open line
" vertical split
noremap <leader>vv :vnew +setl\ buftype=nofile <bar> 0put =v:oldfiles <bar> nnoremap <lt>buffer> <lt>CR> :e <lt>C-r>=getline('.')<lt>CR><lt>CR><CR><CR>
" in new tab
noremap <leader>vt :tabnew +setl\ buftype=nofile <bar> 0put =v:oldfiles <bar> nnoremap <lt>buffer> <lt>CR> :e <lt>C-r>=getline('.')<lt>CR><lt>CR <CR><CR>
When I use the arrow keys in vim in insert mode I get letters inserted instead of movement.
Up produces an A
Down produces a B
Left products a D
Right produces a C
Does anyone know what would cause this?
Thanks in advance
If these keys work fine in normal mode, but do not in insert then you must have some mappings to the first one or two characters (normally <Up> is either <Esc>[A (terminals that use CSI) or <Esc>OA (xterm)). Try checking out output of
verbose imap <Esc>
, there should be not much mappings starting with <Esc> in insert mode (I have none, for example). I can say, that with arrow keys working normally in insert mode, using
inoremap <Esc> <Esc>
produces just the same behavior as if you had problems with terminal recognition or had 'compatible' set.
Your vim seems to be starting in the vi compatibility mode. Do this
Open Vim editor,
Get the path of your home directory by typing :echo $HOME
Check if you have .vimrc file in $HOME location,(if you don't have create it)
Add the following line line to .vimrc file
:set nocompatible
Find more solutions for the same problem here ( Especially if your problem is terminal related, the re-mapping of keys solution might work for you )
The following worked for me. Just put it in your .vimrc
:set term=cons25
Open Vim editor.
Get the path of your home directory by typing: :echo $HOME.
Check if you have .vimrc file in $HOME location, and if you don't have create it.
Add the following line line to .vimrc file: :set nocompatible

None of the answer here worked for me. I'm in Linux, with konsole/yakuake terminal and tmux. This fix works for me:
nnoremap <silent> <ESC>OA <ESC>ki
nnoremap <silent> <ESC>OB <ESC>ji
nnoremap <silent> <ESC>OC <ESC>hi
nnoremap <silent> <ESC>OD <ESC>li
inoremap <silent> <ESC>OA <ESC>ki
inoremap <silent> <ESC>OB <ESC>ji
inoremap <silent> <ESC>OC <ESC>hi
inoremap <silent> <ESC>OD <ESC>li
I'm trying to open a PDF file from Vim using the commands
let openpdfname = "!open " . expand("%:t:r") . ".pdf"
map <F6> :silent execute openpdfname<CR> | redraw!
The PDF opens up in Preview and all is well, except that the Vim screen is not repainted. I use vim 7.2.108 (shipped standard with OSX 10.6) from the terminal window. I tried removing my ~/.vimrc entirely to try and determine the cause, with no luck.
Hitting Ctrl-L repaints the screen, but I thought 'redraw!' would have the same effect!?
Thanks for any hints!
Move <CR> to the end of mapping. You are trying to execute redraw after you exited command mode. Of course, it does not work.
The correct syntax that does what I expect is:
map <F6> :silent execute openpdfname<CR>:redraw!<CR>
Try this:
map <silent> <F6> :silent execute openpdfname<CR>
I have the following code in .vimrc
" to eliminate the effect of the line 1560 in taglist.vim
if v:version >= 700
nnoremap <buffer> <silent> t
\
nnoremap <buffer> <silent> <C-t>
\
endif
The command does what it should do. However, the command gives also me the following error at Vim's startup
No mapping found
No mapping found
How can you eliminate the keyboard shortcut, such that you do not get the message in Taglist but you can still use the default "T" for browsing up in Dvorak?
Delete it. I don't use taglist, but the example you gave in your post does nothing.
It is supposed to map something to something, but the right side is missing, i.e. something is supposed to being mapped to "t" and "C-t", but that something isn't defined.
Or, you can do this:
:silent nnoremap <buffer> <silent> t (and analoguous for the second line)
(mapping stays but the message will not be displayed)
