Agenda optimization: new option `org-agenda-inhibit-startup'

Agenda optimization: new option `org-agenda-inhibit-startup'

[Bastien]

Hi all,

in the maint and master branch, there is `org-agenda-inhibit-startup',
a new option defaulting to t which prevent the agenda buffers to run
some startup initialization when called for generating an agenda --
e.g. opening the buffer with a specific cycling state is not honored.

This will speed up agenda generation *a lot*, especially for people
who have lots of agenda files.

Please check and let me know.

For those who want the previous behavior, simply set it to nil.

I want the default to be t so newbies enjoy a fast agenda early on.

All best,

Seems to work fine and it does seem to speed things up significantly
(although this is a non-quantitative assessment).

Thanks,

Hi Bastien,

yes, this will lead to a speedup of the first agenda in an Emacs session.  Once the buffers have been pulled in, this should not make a difference anymore.

Maybe it would be useful to exempt initializing org-indent-mode from this.  I think (Nicolas?) that this will cost no time as long as the buffer is not visible, but it will help to make the buffer look "right" when the user gets to it.

Mhh.. that's right.  I'll check that (org-indent-mode 1) does not cost
any time when the buffer is not visible.

`org-indent-mode' initializes indentation of buffers even when they are
not current. Though, it happens on idle time, so it shouldn't be
noticeable.

I double-checked and (setq org-startup-indented t) does not delay the
agenda generation, so I implemented this: org-indent-mode is not
inhibited anymore when `org-agenda-inhibit-startup' is non-nil.

Thanks for suggesting this!
