emacs remove any indentation

Here’s another quick one. It could be when formatting pieces of code that you want to remove any space from the beginning of the line. Removing de-facto any indentation.

M-x query-replace-regexp RET
^[[:space:]]+ RET
RET

Confirm then one by one with ‘y‘ or replace all of the buffer with ‘!‘.

emacs strip blank lines

Spiral-Bound Pad (by incurable_hippie)

Here is a quick way to strip (remove) blank lines from a file with emacs.

1. position on top of file: M-<
2. Call a query-regex-replace: M-C-%
3. input the regex ^ C-q C-j that stand for match all lines that consist in only a carriage return.
4. RET-RET. The first one confirm the regex and the last one is for “replace with nothing”.
5. When asked use ! to replace-all.

Summing all commands:

M-< C-M-% ^ C-q C-j RET RET !

here you are 🙂
