Depending on the complexity, it could be as simple as

vim *.txt
:argdo %s/=/,/e|w

or slightly less recklessly,

vim *.txt
:set hidden
:argdo %s/=/,/e
(survey the changes)
:xa " if they're good save & quit all, or
:qa! " if they're bad, abandon all changes

The :s command could be made more complex to tighten the
requirements, something like

%s/^\w\+\zs\s*=\s*\ze\</,/e

which ensures that there's a "word" at the beginning of the line,
followed by some optional whitespace (that will removed), the equals
sign (which will get changed to a comma) followed by more optional
whitespace (that will also get removed), followed by the start of a
word. This can be tweaked depending on the particulars of your
use-case.

Well, there are a couple options, again using ":argdo" to iterate
over all the files. If you want to keep lines that contain
"backslash u hex-digit hex-digit hex-digit hex-digit", you can do

:set hidden
:argdo v/\\u\x\x\x\x/d

then review your changes and either save/abandon the changes.

Alternatively, if you have your original file and just want to keep
the "=" lines even if they don't have hex digits on them (might be
integers or something else?), you can preprocess with

:argdo v/=/d

to delete all the lines that don't contain an "=". You can then run
the previously-provided command to change the "=" to ",".

If you just want to delete those lines starting with a hash, you can use

:argdo g/^\s*#/d

to delete them.

Hi,

I guess you can use the :g command (":help :g"):

:argdo :g/^tom/#

:argdo - do the command for every file in the arg list
:g - run the # command (:help :#) for every line matching the pattern between /.../

If you want to put the output into another buffer you can do redirect it
to a register and paste it somewhere:

:redir @a
:argdo :g/^tom/
:redir end

Now you can paste the output using: "ap in normal mode.

If there is no command specified for the :g command it just prints the
line (:# prints the line with the line number).

Best,
Marcin

Nope...it's a pretty friendly list.

I'm not sure I fully understand what you want here. I don't see any
obvious transformation from your 4 input files to the output you
request, so without a better understanding of what you want, it's
hard to produce a solution.

Operating across multiple files in vim is not always the easiest
thing to do, so I'd suggest a quick external script in
bash/perl/python/ruby.

How about

1) Concatenate and sort all the files, either outside vim and load them into vim, or in, say

:for x in expand('file*',0,1) | exe 'r ' . x | endfor | sort

2) Decorate those of interest, say

:%s/^\(\(.\{-}\),.*\)\n\(\2,.*\)$/\1@!@\r\3@!@/

3) Delete the uninteresting:

:v/@!@/d

4) Remove the decorations:

:%s/@!@//

Steps 2,3,4 could be combined using a look behind regex, I imagine.

Possibly; it depends on your editing style. My guess is "yes". Since you use both Eclipse and Notepad++, I'm guessing you like some of the developer tools in Eclipse but not the text editor.

Vim is not a very good IDE by itself but is an EXCELLENT text editor. And the eclim plugin for Eclipse and Vim lets you access many of the Eclipse developer tools you like from within Vim:
