Tip: adjust indention in text files

MadeInGermany · 03-02-2023, 03:50 AM

I have two executable sed scripts at a location that is in my PATH

Code:

$ cat indent+
#!/usr/bin/sed -f
# Doubles the number of leading spaces
s/^ */&&/

$ cat indent-
#!/usr/bin/sed -f
# Halves the number of leading spaces
s/^\( *\)\1/\1/

If I want to double or halve the number of leading spaces on my test.awk file then I run

Code:

indent+ test.awk
indent- test.awk

and redirect the output to a new file.

If you use tab characters then first replace them with spaces, by using the expand command.
Example

Code:

expand test.awk | indent- > newtest.awk

Sorry, I don't really understand. Every editor has features to [un]indent.

Perhaps I am the only one. Had worked on some deeply nested customer scripts that were 8 characters (or one tab) per indention.
My screen was not wide enough, or the text size became too small.
So I used these utilities to shrink them to my screen size, and after work grow them to the size the customer wanted.

Perhaps not. I like it - much better than bc ...

I downloaded a tool for shell (shfmt) to do full formatting, another one for python and groovy. They called code beautifiers and do much more, not only correct indentations.

I set my tab settings in vim and use tabs command in bashrc to set command line indenting
