optional packages on startup?

optional packages on startup?

[Jai Dayal]

[-- Attachment #1: Type: text/plain, Size: 384 bytes --]

Hi,
  In emacs, I have a lot of things that load up (cscopes, cedet, ecb).
Since I have to ssh into a proxy, and then into the main server, there's a
bit of latency for emacs to start up.

Is there an easy way to say 'emacs simple filename.cpp' and if simple is
present, it skips over some number of packages?  Doing emacs filename.cpp,
however, would load all packages.

Thanks!
Jai

Never do a (require 'package) - either for uncompiled or compiled
packages.

Always compile the installed packages - autoloads ensures that the
packages are loaded on demand. 

There lots of other things that you could do but the above two steps
will ensure visible improvements.

Hi,

what about write into your init-file

(if CONDITION
    load this
   load that)

(file-readable-p) might a suitable condition IIUC

You need to require the autoload file though.

Create a SIMPLE (or basic) init file and launch GNU Emacs as 'emacs -l SIMPLE.el'. A shell alias can help to reduce typing.

My suggestion is to leave a "server" emacs running and then just attach to it when you ssh over.  See emacsclient for more details (or ask this list).

Basically, it's still loading CEDET.  Any idea why?

Hi,

I don't use CEDET.  If you do connect more than once to the same emacs server and it continues to pull in cedet, I would look at your mode hooks first to see what they are doing.  Usually it should use "require /  provide" rather than "load".

Hopefully a more cedet savvy person will reply too.

Good luck,
pedz

Maybe the site-run-file dictates loading of CEDET...

I use '(desktop-save-mode 1)', so even I do not put 'require' it is
too long wait when Emacs loading as I have many files opened with
several different file types (for all of them loaded appropriated
major mode)...

Some times I use code like this:

(eval-after-load 'grep
   '(progn
      (add-to-list 'grep-find-ignored-directories "build" t)
      (add-to-list 'grep-find-ignored-directories "dist" t)
      (add-to-list 'grep-find-ignored-directories "lib" t)

      (when (boundp 'grep-find-ignored-files)
        (add-to-list 'grep-find-ignored-files "*TAGS")
        (add-to-list 'grep-find-ignored-files "GPATH")
        )
      ))

to prevent from loading grep.el at sturtup.
