I'm using Emacs to write ocaml programs, and the automatic indentation works fine : suppose I write if in the middle of a line, then skip a line and write then ; the keyword then is automatically aligned with my if.

But if I later decide to add some code before the if, and the position of the if thus changes, then remains aligned with the previous position of the if until I manually add (and immediately remove) a lineskip on the line that has my then so that the indentation is recalculated.

Is there a way to ask Emacs to reindent all lines in my document without having to add-and-remove lineskips everywhere to force Emacs to recalculate the correct indentation line by line?

  • I had never heard the word` lineskip` used in this way. Usually we call it "newline" or "LF". – Stefan Nov 9 '18 at 14:00

    Have you tried the indent-buffer interactive function (M-x indent-buffer)? indent-region may also be useful. – ebpa Nov 9 '18 at 14:01

Normally, the TAB key (indent-for-tab-command) reindents the current line and C-M-\ (indent-region) reindents the region.

For a completely automated solution use the package aggressive-indent.
