31 ;; Major mode for editing shell scripts. Bourne, C and rc shells as well
|
|
|
32 ;; as various derivatives are supported and easily derived from. Structured
|
|
|
33 ;; statements can be inserted with one command or abbrev. Completion is
|
|
|
34 ;; available for filenames, variables known from the script, the shell and
|
|
|
35 ;; the environment as well as commands.
|
|
|
36
|
|
|
37 ;;; Known Bugs:
|
|
|
38
|
|
|
39 ;; - In Bourne the keyword `in' is not anchored to case, for, select ...
|
|
|
40 ;; - Variables in `"' strings aren't fontified because there's no way of
|
|
|
41 ;; syntactically distinguishing those from `'' strings.

685 "Major mode for editing shell scripts.
|
|
|
686 This mode works for many shells, since they all have roughly the same syntax,
|
|
|
687 as far as commands, arguments, variables, pipes, comments etc. are concerned.
|
|
|
688 Unless the file's magic number indicates the shell, your usual shell is
|
|
|
689 assumed. Since filenames rarely give a clue, they are not further analyzed.
|
|
|
690
|
|
|
691 This mode adapts to the variations between shells (see `sh-set-shell') by
|
|
|
692 means of an inheritance based feature lookup (see `sh-feature'). This
|
|
|
693 mechanism applies to all variables (including skeletons) that pertain to
|
|
|
694 shell-specific features.
|
|
|
695
|
|
|
696 The default style of this mode is that of Rosenblatt's Korn shell book.
|
|
|
697 The syntax of the statements varies with the shell being used. The
|
|
|
698 following commands are available, based on the current shell's syntax:
|
|
|
699
|
|
|
700 \\[sh-case] case statement
|
|
|
701 \\[sh-for] for loop
|
|
|
702 \\[sh-function] function definition
|
|
|
703 \\[sh-if] if statement
|
|
|
704 \\[sh-indexed-loop] indexed loop from 1 to n
|
|
|
705 \\[sh-while-getopts] while getopts loop
|
|
|
706 \\[sh-repeat] repeat loop
|
|
|
707 \\[sh-select] select loop
|
|
|
708 \\[sh-until] until loop
|
|
|
709 \\[sh-while] while loop
|
|
|
710
|
|
|
711 \\[backward-delete-char-untabify] Delete backward one position, even if it was a tab.
|
|
|
712 \\[sh-newline-and-indent] Delete unquoted space and indent new line same as this one.
|
|
|
713 \\[sh-end-of-command] Go to end of successive commands.
|
|
|
714 \\[sh-beginning-of-command] Go to beginning of successive commands.
|
|
|
715 \\[sh-set-shell] Set this buffer's shell, and maybe its magic number.
|
|
|
716 \\[sh-execute-region] Have optional header and region be executed in a subshell.
|
|
|
717
|
|
|
718 \\[sh-maybe-here-document] Without prefix, following an unquoted < inserts here document.
|
|
|
719 {, (, [, ', \", `
|
|
|
720 Unless quoted with \\, insert the pairs {}, (), [], or '', \"\", ``.
|
|
|
721
|
|
|
722 If you generally program a shell different from your login shell you can
|
|
|
723 set `sh-shell-file' accordingly. If your shell's file name doesn't correctly
|
|
|
724 indicate what shell it is use `sh-alias-alist' to translate.
|
|
|
725
|
|
|
726 If your shell gives error messages with line numbers, you can use \\[executable-interpret]
|
|
|
727 with your script for an edit-interpret-debug cycle."
