Emacs F90 Mode Quick Reference

f90-mode is a major mode for GNU Emacs for editing free-form Fortran source code. f90-mode is part of GNU Emacs and therefore no installation is required. To ensure that f90-mode loads when editing .f90 files and to turn on abbrev-mode and the maximum level of syntax highlighting, add the following to your ~/.emacs file:

(autoload 'f90-mode "f90" "Fortran 90 mode" t)
(add-hook 'f90-mode-hook 'my-f90-mode-hook)

(defun my-f90-mode-hook ()
  (setq f90-font-lock-keywords f90-font-lock-keywords-3)
  (abbrev-mode 1)                       ; turn on abbreviation mode
  (turn-on-font-lock)                   ; syntax highlighting
  (auto-fill-mode 0))                   ; turn off auto-filling

Editing Commands

Compilation Commands

The usual emacs compilation system can be used with Fortran programs. If you have a Makefile for the project you are editing, use M-x compile to call make -k in the current directory. Compiler output will be shown in a separate window. To jump to the first error or warning press C-x `. Pressing this again will jump to the next error and so on.
