22 | ;;; Commentary: |
23 | ||
24 | ;; Eshell, by using the pcomplete package, provides a full | |
25 | ;; programmable completion facility that is comparable to shells like | |
26 | ;; tcsh or zsh. | |
27 | ;; | |
28 | ;; Completions are context-sensitive, which means that pressing <TAB> | |
29 | ;; after the command 'rmdir' will result in a list of directories, | |
30 | ;; while doing so after 'rm' will result in a list of all file | |
31 | ;; entries. | |
32 | ;; | |
33 | ;; Many builtin completion rules are provided, for commands such as | |
34 | ;; `cvs', or RedHat's `rpm' utility. Adding new completion rules is | |
35 | ;; no more difficult than writing a plain Lisp functions, and they can | |
36 | ;; be debugged, profiled, and compiled using exactly the same | |
37 | ;; facilities (since in fact, they *are* just Lisp functions). See | |
38 | ;; the definition of the function `pcomplete/make' for an example of | |
39 | ;; how to write a completion function. | |
40 | ;; | |
41 | ;; The completion facility is very easy to use. Just press TAB. If | |
42 | ;; there are a large number of possible completions, a buffer will | |
2696c102 | 43 | ;; appear showing a list of them. Completions may be selected from |
affbf647 GM |
44 | ;; that buffer using the mouse. If no completion is selected, and the |
45 | ;; user starts doing something else, the display buffer will | |
46 | ;; automatically disappear. | |
47 | ;; | |
48 | ;; If the list of possible completions is very small, Eshell will | |
49 | ;; "cycle" through them, selecting a different entry each time <TAB> | |
50 | ;; is pressed. <S-TAB> may be used to cycle in the opposite | |
51 | ;; direction. | |
52 | ;; | |
53 | ;; Glob patterns can also be cycled. For example, entering 'echo | |
54 | ;; x*<tab>' will cycle through all the filenames beginning with 'x'. | |
55 | ;; This is done because the glob list is treated as though it were a | |
56 | ;; list of possible completions. Pressing <C-c SPC> will insert all | |
57 | ;; of the matching glob patterns at point. | |
58 | ;; | |
59 | ;; If a Lisp form is being entered, <TAB> will complete the Lisp | |
60 | ;; symbol name, in exactly the same way that <M-TAB> does in Emacs | |
61 | ;; Lisp mode. | |
62 | ;; | |
63 | ;; The list of possible completions can be viewed at any point by | |
64 | ;; pressing <M-?>. | |
65 | ;; | |
4b9f0b67 | 66 | ;; Finally, context-related help can be accessed by pressing <C-c M-h>. |
affbf647 GM |
67 | ;; This only works well if the completion function has provided Eshell |
68 | ;; with sufficient pointers to locate the relevant help text. | |
