22 | ;;; Commentary: |
23 | ||
24 | ;; Eshell's history facility imitates the syntax used by bash | |
25 | ;; ([(bash)History Interaction]). Thus: | |
26 | ;; | |
27 | ;; !ls ; repeat the last command beginning with 'ls' | |
28 | ;; !?ls ; repeat the last command containing ls | |
29 | ;; echo !ls:2 ; echo the second arg of the last 'ls' command | |
30 | ;; !ls<tab> ; complete against all possible words in this | |
31 | ;; ; position, by looking at the history list | |
32 | ;; !ls<C-c SPC> ; expand any matching history input at point | |
33 | ;; | |
34 | ;; Also, most of `comint-mode's keybindings are accepted: | |
35 | ;; | |
36 | ;; M-r ; search backward for a previous command by regexp | |
37 | ;; M-s ; search forward for a previous command by regexp | |
38 | ;; M-p ; access the last command entered, repeatable | |
39 | ;; M-n ; access the first command entered, repeatable | |
40 | ;; | |
41 | ;; C-c M-r ; using current input, find a matching command thus, with | |
42 | ;; ; 'ls' as the current input, it will go back to the same | |
43 | ;; ; command that '!ls' would have selected | |
44 | ;; C-c M-s ; same, but in reverse order | |
45 | ;; | |
46 | ;; Note that some of these keybindings are only available if the | |
47 | ;; `eshell-rebind' is not in use, in which case M-p does what C-c M-r | |
48 | ;; normally would do, and C-p is used instead of M-p. It may seem | |
49 | ;; confusing, but the intention is to make the most useful | |
50 | ;; functionality the most easily accessible. If `eshell-rebind' is | |
51 | ;; not being used, history navigation will use comint's keybindings; | |
52 | ;; if it is, history navigation tries to use similar keybindings to | |
53 | ;; bash. This is all configurable, of course. | |
