Indenting in VIM with all the files in Folder

Question

I have a folder containing hundreds of TTL (TeraTermLanguage) files. Now I wanted indent all these files.

I have created teraterm.vim for indentation and I open a file using VIM and do "gg=G" and whole file gets indented properly.

But is there any way, where I can indent all the files in folder.

I wanted to do with help of Shell. But in VIM I couldnt pass file indent command as the argument to VIM.

Please suggest which is the best way I can do indentation to all the files in VIM.

Answer 1

Much simpler than scripting vim from the bash command line is to use vimscript from inside of vim (or perhaps a much simpler one-liner for scripting vim from the command line). I personally prefer using the arg list for all multi-file manipulation. For example:

:args ~/src/myproject/**/*.ttl | argdo execute "normal gg=G" | update 

• args sets the arglist, using wildcards (** will match the current directory as well as subdirectories)
• | lets us run multiple commands on one line
• argdo runs the following commands on each arg (it will swallow up the second |)
• execute prevents normal from swallowing up the next pipe.
• normal runs the following normal mode commands (what you were working with in the first place)
• update is like :w, but only saves when the buffer is modified.

This :args ... | argdo ... | update pattern is very useful for any sort of project wide file manipulation (e.g. search and replace via %s/foo/bar/ge or setting uniform fileformat or fileencoding).

(other people prefer a similar pattern using the buffer list and :bufdo, but with the arg list I don't need to worry about closing current buffers or opening up new vim session.)

Answer 2

Open up a terminal. Type:

$ vim -w indentme.scr foo.c 

Then, type this exactly (in command mode):

gg=G:wq 

This will close vim, saving the process of indenting all lines in the file to a Vim script called indentme.scr.

Note: indentme.scr will contain a record of all key commands typed, so when you are done indenting the file, don't spend a lot of time using the arrow keys to look around the file, because this will lead to a much larger script and will severely slow down batch operations.

Now, in order to indent all the lines in a file, just type the following command:

$ vim -s indentme.scr unindented-file.c 

Vim will flash open-shut (if you're on a fast computer and not editing a huge file), indenting all lines, then saving the file in-place.

Unfortunately, this will only work on one file at a time, but you can scale the functionality easily using sh's for loop:

for filename in *.ttl ; do     vim -s indentme.scr "$filename" done 

Note: This will save-over any file. Unless set bk is in your ~/.vimrc, don't expect a backup to be saved.
