Replace spaces with tabs & format file source recursively within a directory

Recursively find php files and replace tab characters with spaces.

Options:

"\*.php" -- replace this with the files you wish to find

"expand" -- replace tabs with spaces (use "unexpand" to replace spaces with tabs)

"-t4" -- tabs represent 4 spaces

Note: The IFS="" in the middle is to prevent 'read' from eating leading/trailing whitespace in filenames.

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives
find $DIR -name *.php -exec vim -u NONE -c 'set ft=php' -c 'set shiftwidth=4' -c 'set tabstop=4' -c 'set noexpandtab!' -c 'set noet' -c 'retab!' -c 'bufdo! "execute normal gg=G"' -c wq {} \;

The sample command searches for PHP files replacing tabs with spaces.

-u NONE # don't use vimrc

Instead of

retab!

one may pass

retab! 4

for instance.

Know a better way?

If you can do better, submit your command here.

What others think

flatcap, it expands/unexpands *all* file contents. Isn't it?

While my command uses smart vim formatting to *indent* using tabs, not touching those in strings, for instance

Really? Unfortunately, I can't get your command to work.

From the vim help on retab: Careful: This command modifies any characters inside of strings in a C program. Use "\t" to avoid this (that's a good habit anyway).

By adding --initial to expand (or --first-only to unexpand), it will only work on leading whitespace.

As a heavy user of vim, I'd have done this by macro or bufdo. Spawning vim for every file will really slow things down.

flatcap, what about constructions like

$a = array( 'key1' => '12', 'longlongkey' => 'someghing', 'second-long-k' => 12.34, );

?

It didn't format like what I mean. Look at this: http://susepaste.org/28853675
