26.14.2.1 Fortran Indentation and Filling Commands
- C-M-j
- Break the current line at point and set up a continuation line (
fortran-split-line). - M-^
- Join this line to the previous line (
fortran-join-line). - C-M-q
- Indent all the lines of the subprogram that point is in (
fortran-indent-subprogram). - M-q
- Fill a comment block or statement (using
fortran-fill-paragraphorfortran-fill-statement).
The key C-M-q runs fortran-indent-subprogram, a command to reindent all the lines of the Fortran subprogram (function or subroutine) containing point.
The key C-M-j runs fortran-split-line, which splits a line in the appropriate fashion for Fortran. In a non-comment line, the second half becomes a continuation line and is indented accordingly. In a comment line, both halves become separate comment lines.
M-^ or C-c C-d run the command fortran-join-line, which joins a continuation line back to the previous line, roughly as the inverse of fortran-split-line. The point must be on a continuation line when this command is invoked.
M-q in Fortran mode fills the comment block or statement that point is in. This removes any excess statement continuations.
