;; A monkey patch to add several substitutions to evil-mode's ex commandline
|
||||
;; other than % and #...
|
||||
;;
|
||||
;; % => full path to file (/project/src/thing.c)
|
||||
;; # => alternative file path (/project/include/thing.h)
|
||||
;; %:p => path to project root (/project/)
|
||||
;; %:d => path to current directory (/project/src/)
|
||||
;; %:e => the file's extension (c)
|
||||
;; %:r => the full path without its extension (/project/src/thing)
|
||||
;; %:t => the file's basename (thing.c)
|
||||
;;
|

;; Requires projectile (https://github.com/bbatsov/projectile) for
|
||||
;; project-awareness, and f.el (https://github.com/rejeep/f.el) for file
|
||||
;; functions.
|
||||
;; A monkey patch to add all of vim's file ex substitution flags to evil-mode.
