Subject: customize hideshow.el?
Date: Sun, 13 Aug 2017 11:46:55 -0500 [thread overview]
Message-ID: <861sofza80.fsf@stephe-leake.org> (raw)
I'd like to customize hideshow.el to display the first and last line in
each hidden block.
This makes sense (at least to me) for languages like Ada. For example,
suppose I have an "if then else" statement nested in a block:
declare
begin
if then
elsif then
else
end if;
exception
end;
But I realize the declare block is only needed in the first branch of
the if, so I'd like to change this to:
if then
declare
begin
exception
end;
elsif then
else
end if;
If all the code fits in one window, this is not hard. But if the "if
then else" is long, I'd like to hide it, so I can easily delete the
"declare begin" and "exception end". But I'd like to be sure where the
beginning and end of the "if then else" is, so I don't accidently delete
part of it:
declare
begin
if then
...
end if;
exception
end;
However, hideshow.el, without any customizations, does this:
declare
begin...exception
end;
I've looked into the hooks in hide-show; I can set
hs-adjust-block-beginning to get this:
declare
begin
if then...exception
end;
but there is no corresponding hs-adjust-block-end hook.
Before I start trying to add hs-adjust-block-end, I'm looking for
advice.
Is there any way to use the existing hooks to get what I want?
Are there other modes like hideshow.el that are closer to what I want?
Anyone else want what I want?
