Indentinator is a script that inspects and changes the indentation in your source code. It is language-agnostic. "Indent your code the way you want."
Install
Assuming you have ruby and rubygem installed, you can
gem install Indentinator
to install it.
Usage
indentinator [-c INDENT_AMOUNT] <file> [<file2>...]
Examples
Using indentinator with a file argument will tell you what amount of indentation the file uses.
$ indentinator lib/myapp.rb
lib/myapp.rb uses 2 spaces.
Using with the -c option will convert the file to the desired indentation amount, and print the result to stdout.
$ indentinator -c 4 lib/myapp.rb
The -r option will overwrite the original file with the output.
$ indentinator -rc 4 lib/myapp.rb
Make sure you have the file backed up or source controlled first! I am not responsible for any damages.
If you want to read the input from stdin, use the -i option
$ cat lib/myapp.rb | indentinator -ic 4
If you use a mixture of indentation sizes in your source file, indentinator may guess wrong, which will in turn affect the conversion output. To tell it
explicitly the original indentation amount for it to use during the conversion
process use the -a option
$ indentinator -a 4 -c lib/myapp.rb
Totally Use it Inside TextMate and Stuff
If you copied a snippet of code from the internets, and it uses a different indentation then you, it will be helpful to use indentinator from within TextMate. To do this, follow these steps:
- Go to
TextMate->Preferences...->Advanced->Shell Variables, and make sure thePATHvariable contains the location of theindentinatorexecutable. - Paste the code snippet into TextMate, select that snippet and hit Command-Option-R.
- In the
Command:text field type in the indentinator command to use, for exampleindentinator -ic 2, which will take the selected text as input (fromstdin) and output it with an indentation of 2 spaces. - Click
Execute.
