I'm working with big, nested workspaces and often I don't remember the exact path to the file, only its filename or part of the filename. If I know some of the text in the file, I could always recursively use 'vimgrep', but for searching on filenames alone I have been using:
:!find . -name ...
to locate the file and then edit it. I was trying to find if there is some solution directly in Vim, and haven't found one. Closest were :find and :globpath(). :find works nearly as I need, but unfortunatelly it opens the first file of a given name without telling me that there are more. For globpath() I was unable to make it work with the '**' construction, so that it would look into all subdirectories under current directory.
So I wrote this small function. You can use it like this:
:Find whatever.c - this opens the file "src/core/whatever.c"
If there is more than one match, it will present you a selection:
:Find Makefile 1 ./src/Makefile 2 ./src/core/Makefile 3 ./src/api/Makefile ... 89 ./src/deelply/hidden/Makefile 90 ./Makefile Which ? (CR=nothing)
You may also use wildchars (whatever find(1) knows).
:Find *stream*.c 1 ./src/core/i_stream.c 2 ./src/core/o_stream.c 3 ./src/core/streamio.c Which ? (CR=nothing)
The function itself:
" Find file in current directory and edit it.
function! Find(name)
let l:list=system("find . -name '".a:name."' | perl -ne 'print \"$.\\t$_\"'")
let l:num=strlen(substitute(l:list, "[^\n]", "", "g"))
if l:num < 1
echo "'".a:name."' not found"
return
endif
if l:num != 1
echo l:list
let l:input=input("Which ? (CR=nothing)\n")
if strlen(l:input)==0
return
endif
if strlen(substitute(l:input, "[0-9]", "", "g"))>0
echo "Not a number"
return
endif
if l:input<1 || l:input>l:num
echo "Out of range"
return
endif
let l:line=matchstr("\n".l:list, "\n".l:input."\t[^\n]*")
else
let l:line=l:list
endif
let l:line=substitute(l:line, "^[^\t]*\t./", "", "")
execute ":e ".l:line
endfunction
command! -nargs=1 Find :call Find("<args>")
[edit] Comments
You can load an arbitrary list of files with :args <pattern>, for instance:
Open all .c or .h files in the directory (and it's subdirectories) two directories up from the current directory:
- args ../../**/*.[ch]
The only caveat (and it's a major one) is that it's very slow.
There's also the :Explore **/[pattern] command, available via netrw.vim. Example:
:Explore **/*.vim
This command will show the current match number out of the total quantity of matches in the status line, and one may move forwards and backwards in the matching files list. Hitting the <cr> on a matching file opens the file, of course.
When I try the :Explore command it gives error: E77: Too many file names
Adding a quit button is not a bad idea. Vim internal pager has quit bound to 'q' (see :help more-prompt), but this will stop my original script. I tried to use try-catch block around and it seems to work.
if l:num != 1
try
echo l:list
catch /.*/
endtry
let l:input=input("Which ? (CR=nothing)\n")
I think, it will be better to use vimgrep for find, than it works also under windows. I don't know how.
Here is a version the exclude subversion directory:
function! Find(name)
let l:list=system("find . -name '".a:name."' | grep -v \".svn/\" | perl -ne 'print \"$.\\t$_\"'")
let l:num=strlen(substitute(l:list, "[^\n]", "", "g"))
if l:num < 1
echo "'".a:name."' not found"
return
endif
if l:num != 1
echo l:list
let l:input=input("Which ? (CR=nothing)\n")
if strlen(l:input)==0
return
endif
if strlen(substitute(l:input, "[0-9]", "", "g"))>0
echo "Not a number"
return
endif
if l:input<1 || l:input>l:num
echo "Out of range"
return
endif
let l:line=matchstr("\n".l:list, "\n".l:input."\t[^\n]*")
else
let l:line=l:list
endif
let l:line=substitute(l:line, "^[^\t]*\t./", "", "")
execute ":e ".l:line
endfunction
command! -nargs=1 Find :call Find("<args>")
Here is a other nice solution to vimrc
if exists("$PROJECTDIR")
set path=$PROJECTDIR/**
set tags=$PROJECTDIR/tags
endif
well, is on the shell $PROJECTDIR defined the include recursive all directories.
with :find foo.cpp it's open the file on Vim.
Yes, I have been using construct very similar to yours, the trouble was that :find opens first file of a given name it finds, without telling you that there are other two.
The other thing, :find also does not like wildcard characters, they are expanded before the :find is executed. I would like to be able to use ':find blah*.c'. Or maybe I just don't know how to use :find properly ? :)
The tags mechanism is how I jump around files. The Exuberant Ctags tool allows you to tag the files themselves.
I have a script that looks like this:
ctags --extra=+f --langdef=file --langmap='file:.xml.jsp.properties.xslt' \ --exclude=WEB-INF/classes \ -R src/com src/java testharness/src web/pages sql gen WEB-INF
In your Vim session set the tags file location
:set tags=pathtotags/tags
And then use :tag FileName
Added bonus, :tag lets you use tab completion!
>> But maybe there is some way to generate two different tag files and use them in Vim at the same time?
Sure there is! You can try:
set tags=<path1>/tags,<path2>,tags
Thank you, very useful script. Would it be possible to add an option to open the found file with another program? For example openoffice in case the found file is odt?
If the user has no permission for some of the files, they are included in the listing. I solved it by redirecting stderr to /dev/null.
Old line:
let l:list=system("find . -name '".a:name."' | grep -v \".svn/\" | perl -ne 'print \"$.\\t$_\"'")
New line:
let l:list=system("find . -name '".a:name."' 2> /dev/null | grep -v \".svn/\" | perl -ne 'print \"$.\\t$_\"'")
