sh-script-mode

[Cai Qian]

Hi,

I would like to change the behaviour of default sh-script-mode through
.emacs about the following,

1) Here document,
When input <<, it should not automatically add EOF here document for
me, as I may want to use <<< instead. Therefore, I want to disable
this feature.

2) Case statement,
At the moment the default indention style is,

case $1 in
       -h)
       usage
       ;;

I want to change to

case $1 in
-h)
     usage
     ;;

3) Highlight for quota string
I want to disable syntax highlight for quota string, as it is a mess
when embed double or single quota inside quota, such as,

echo "$(echo "hello 'world'")"

Thanks,
Qian

Hi,

There are two bugs regards sh-script-mode

1) Here document,
When input <<, it should not automatically add EOF here document for
me, as I may want to use <<< instead.

3) Highlight for quota string
Highlight for quota string is a mess, when embed double or single
quota inside quota, such as,

echo "$(echo "hello 'world'")"

Not tested:

(add-hook 'sh-mode-hook
          (lambda () (local-set-key ?< 'self-insert-command)))

Try (a) `C-u <' instead of just `<', (b) setting sh-here-document-word
to "", or (c) unbinding "<" in Shell-script mode's local map
(sh-mode-map).

I think it is necessary here to change the behaviour of syntax
highlight of quote string. For example,

echo "$(ls "Hello World"*)"

Two quote strings are valid and necessary here to protect spaces as
well as newlines. In addition, I don't think it is too hard to support
it. When the first " char looking for the end of " char, it needs to
skip " char inside $(...)
