Vim: open files of the matches on the lines given by Grep?

Question

I want to get automatically to the positions of the results in Vim after grepping, on command line. Is there such feature?

Files to open in Vim on the lines give

Answer 1

You probably want to make functions for these. :)

Sequential vim calls (console)

grep -rn "implements" app | # Or any (with "-n") you like
  awk '{
    split($0,a,":"); # split on ":"
    print "</dev/tty vim", a[1], "+" a[2] # results in lines with "</dev/tty vim <foundfile> +<linenumber>
  }' |
  parallel --halt-on-error 1 -j1 --tty bash -ec # halt on error and "-e" important to make it possible to quit in the middle

Use :cq from vim to stop editing.

Concurrent opening in tabs (gvim)

Start the server:

gvim --servername GVIM

Open the tabs:

grep -rn "implements" app | # again, any grep you like (with "-n")
  awk "{ # double quotes because of $PWD
    split(\$0,a,\":\"); # split on ":"
    print \":tabedit $PWD/\" a[1] \"<CR>\" a[2] \"G\" # Vim commands. Open file, then jump to line
  }" | 
  parallel gvim --servername GVIM --remote-send # of course the servername needs to match

Answer 2

If you pipe the output from grep into vim

% grep -n checkWordInFile * | vim -

you can put the cursor on the filename and hit gF to jump to the line in that file that's referenced by that line of grep output. ^WF will open it in a new window.

From within vim you can do the same thing with

:tabedit
:r !grep -n checkWordInFile *

which is equivalent to but less convenient than

:lgrep checkWordInFile *
:lopen

which brings up the superfantastic quickfix window so you can conveniently browse through search results.

You can alternatively get slower but in-some-ways-more-flexible results by using vim's native grep:

:lvimgrep checkWordInFile *
:lopen

This one uses vim REs and paths (eg allowing **). It can take 2-4 times longer to run (maybe more), but you get to use fancy \(\)\@<=s and birds of a feather.
