* how to find auto-saved files that need recovering
find a recently dated file in ~/.emacs.d/auto-save-list/, and see the files listed in it.
#file# is an auto-save file. It may or may not be different than the file is corresponds to.
If it is different, emacs will give a message about recovering it when you open it.

* TODO add simpler keybind for make-frame-command
current one is C-x 5 2.

* TODO learn some more ivy mode stuff
* TODO declarative package installations,
with documentation.
* TODO shell mode reverse search hides 2nd+ line of multi-line result
* TODO figure out browsing files with broken nfs mount
causes emacs to freeze until I kill -9 it.
* TODO make a keybind to print var under cursor
and actually, putting the start of it in th emodeline might be cool
* TODO make recent files save periodically,
normally it just saves on exit, but half the time I don't exit cleanly
so they don't get saved, because I leave emacs running until it crashes
* TODO fix undo tree outside visible buffer bug
* TODO c-<delete> in shell mode should send over
previous line if current line is empty
* TODO make c-m-s be just a control key for easier use
* TODO try out avy mode for laptop
i used to have ace jump mode, but google says avy is better.
* TODO bind a in group mode of gnus to c-u a,
also, make a default for number of articles
* TODO make auto-complete be on by default in sql-mode
* TODO make an easy bind for open previous buffer
* TODO i think my autosave for sudo-edit might be too fast
it sometimes leaves #_asdfjasdf files littered
* TODO readline-compleste doesn't work when you cat a file without a newline,
and so the prompt is messed up. not sure exactly what needs to be in end, or if its anything
* TODO figure out how to paste a path into find file
probably have to use the old kind of find file
* TODO readline-complete doesn't escape special chars in filenames
* TODO readline-complete dev



** misc fixes

bad code, the comment this relates to was removed, but not the comment
              /* If waiting for this channel, arrange to return as
                 soon as no more input to be processed.  No more
                 waiting.  */


(status_notify): New arg WAIT_PROC. this is unused, this is a bug.
The change in status_notify's return is just passing more information
from what it did already. No changes at all inside this function.

* TODO consider whether to bind indent-for-tab-command
I removed it from m-tab for terminal compatibility.
It's the default tab command, which yasnippet replaces.
* TODO readline-complete: remove the hardcoded rlc-no-readline-hook
* TODO isearch doesn't automatically wrap in info
* TODO look into fixing shell mode reverse search
and why auto-complete dies
caveat is that it doesn't work well with certain unusual prompts, for example if $/# is not used at the end
see if we can load history, or reverse search with history commands
* TODO keybinds for s-delete/tab etc
* TODO fix bbdb info packaging in melpa
* TODO figure out why my emacs startup script doesn't work from dmenu
* TODO post idea to make customize group show function var names so we can read doc strings
* TODO report/fix bug that kill-whole-line doesn't work right with append kill
* TODO make bash keybind for copy paste interoperate with x windows
* TODO fix org stderr redirection
make this produce output of "ok"
#+begin_src sh
echo ok >&2

#+end_src
* TODO make ido keybinds better
* TODO fix indenting in org

          (move-beginning-of-line 2)))))



org-indent-region is broken for source blocks
the above function works, but has several problems.
first: it should not have separate logic from org-indent-line
second: it runs way too slow, mainly the command
 (org-babel-do-in-edit-buffer (indent-according-to-mode)))


* TODO figure out newline in prompt shell issue
setting this before readline-complete is loaded allows completion to work,
but auto-completion still fails. Need to debug readline-complete to figure this out.
(setq shell-prompt-pattern "^[^#$%>]*[#$]\n")
* TODO setup bind for find tag / lisp function at point

* TODO org-delete-char should also work for the delete/backspace keys!
  fix and send patch

* TODO checkout projectile / graphene's project settings

* TODO check up on recent changes to 3rd party default configs
- last checked apr 24
  https://github.com/eschulte/emacs24-starter-kit/commits/master

last checked mayish
https://github.com/bbatsov/prelude
- redefined mouse functions from this file

* TODO figure out how to setup emacs to format text nicely like thunderbird
* TODO it appears impossible make C-[ not be the same as escape
* TODO movement within info buffer after opening a link doesn't cancel isearch
leads to many frustrations
* TODO fix org resolve clock message. it is innacurate
  i is not the same, becuase it does not make org realize there is an active clock

* TODO add apropos commands to help prefix, from
  http://stackoverflow.com/questions/3124844/what-are-your-favorite-global-key-bindings-in-emacs
* TODO my autosave goes into an endless prompting loop
when running save buffer, and the buffer has been changed
outside of emacs
* TODO smart peren does not see ?\\) as a valid paren

* TODO why does org-end-of-line not go all the way to the end on a closed headline?
* TODO org makes random ... things, and delete right before them does ctrl-i
* TODO try mark word, which might be a useful keybind
* TODO fix org-cycle: it assumes which key it is bound to for its last alternative
* TODO checkout lisp-complete-symbol to augment auto-complete
* TODO emacs keylogger to optimize key binds
* TODO remap/investigate find tag, find tag at point
* TODO set key to cycle buffers by mode, example below

(defun cycle-buffer-by-mode (p-mode)
  "Cycle buffers by mode name"
  (interactive)
  (dolist (buffer (buffer-list))
    (with-current-buffer buffer
      (when (buffer-live-p buffer)
        (if (string-match p-mode mode-name) ;(regexp-quote p-mode)
            (setq switch2buffer buffer)))))
  (when (boundp 'switch2buffer)
    (switch-to-buffer switch2buffer)))

And I have bound this to my F9 key

(global-set-key [f9]             '(lambda () (interactive) (cycle-buffer-by-mode "Shell$")))

* TODO test out usefulness of forward/back sexp in different languages

* TODO major mode settings to check out in future

[[http://ourcomments.org/Emacs/nXhtml/doc/nxhtml.html][Nxhtml]] is a large package of utilities for web development and for
embedding multiple major modes in a single buffer.

Nxhtml is not installed in this version of the starter-kit by default,
for information on installing nxhtml see [[http://www.emacswiki.org/emacs/NxhtmlMode][EmacsWiki-Nxhtml]].

background:
      the faq suggests to auto-save using
(setq auto-save-visited-file-name t)
        and to toggle auto-saving in the current buffer, type `M-x auto-save-mode'

        however, this is  buggy.
        it leaves around lock files, which can be disabled with
        (setq create-lockfiles nil)
        but it is also buggy on other things that appear to hook onto file saving
        so i created my own function, which originally had bugs,
        but new emacs version fixed all that, yay!.


; not using, but here for documentation,
; alternate way to enable and specify how long between autosaves.
        ; number of input events between autosave.
        ; lowest bound of functionality is actually about 15 input events

Things I tried which didn't work, which intuitively I think should work better: I can open the second diff buffer in a new frame, and close it's window in the first frame after starting ediff, but when I hit n to go to the next diff, it restores the window in the first frame. Another thing I tried is to open 2 new frames and set them up as I want. However, if I try to open the *Ediff Control Panel* buffer in a different window from its original one, my mouse jumps to one of the diff frames, or if that isn't visible, the buffer just hangs until I select the original ediff control panel window. This seems like a bug to me. I am using a very recent development version of emacs.

* gnus

good info http://www.emacswiki.org/emacs/GnusTutorial
good info http://www.emacs.uniyar.ac.ru/doc/em24h/emacs183.htm


After downloading mailing list archives, once you have an mbox file,
there are rather straightforward ways to get it into any mail program,
but I will cover gnus, which I use and is a bit tricky.

gnus has a native search (limited, too slow for body text searches), and external search engine integration.
gnus manual recommends converting to maildir for searching local mail, but importing lots of maildir messages to gnus
takes 10+ minutes, so scratch that option. it suggests 2 alternate options
mairix. for mbox, it doesn't integrate 100% with gnus, it copies the search results to a mbox
and tells gnus to make a group of that mbox and display it. This means the read state won't be persistent, but otherwise
works great.

local imap server which will use the mbox and provide search.
dovecot is modular, theres a dovecot-common which uses recommends to install i guess it's most used modules. Its
description is completely not useful. Anyways, I'm not sure if there is any benefit to installing this over just the
module we need.
pi dovecot-imapd

dovecot by default also makes a an inbox folder based on the normal local mail location /var/mail/<username>
those locations are adjustable and well documented via the var mail_location in
/etc/dovecot/conf.d/10-mail.conf
I forward my local mail, didn't see immediately how to turn off the inbox, but it will always be empty, so I left as
is. you could make the var be empty, which apparently has the same effect.

Originally just linked the default location ~/.mail, but I changed to altering the config since ~/.mail since it seems
other things like postfix use that location

based on http://roland.entierement.nu/blog/2010/09/08/gnus-dovecot-offlineimap-search-a-howto.html
other links that poped up contained outdated, innacurate information
http://sachachua.com/blog/2008/05/geek-how-to-use-offlineimap-and-the-dovecot-mail-server-to-read-your-gmail-in-emacs-efficiently/
http://www.emacswiki.org/emacs/JamesFerguson
http://www.sanityinc.com/articles/read-mailing-lists-in-emacs-over-imap/

Within emacs you can move messages between mbox and maildir etc, which is a nice flexibility.



doc group for mbox:
in gnus, do gnus-group-make-doc-group (G f in groups buffer) and point to the file

info about groups created within gnus is stored in ~/.newsrc.eld
also stored is a duplication of what email messages are read/unread,
what newsgroups are subsribed to and read/unread,
probably more stuff, everything that gnus saves.


searching the body of the messages, i cut off after a few minutes.
i can grep the file in just a couple seconds


random side note
we can also get mbox from gmane
http://notmuchmail.org/howto/#index7h2


gnus can't search mboxes except with its builtin search which is extremely slow. mairix can do mbox files from the command
line, but not from within gnus, but from mairix.el, which can then open the results in gnus

mbox can be converted to maildir easily, but gnus loads lots of maildir messages extremely slow. it parses all the
headers and generates a nov file for each.

nnfolder-generate-active-file

to reset things, when changing mail group. I duno all the proper way, but it works to delete
~/Mail ~/.newsrc.eld ~/.dribble (or something)


** mail sources vs select methods background
I found this very confusing when first reading through the manual.  "mail sources" is a term that does not simply mean
sources of mail, it is much narrower for gnus. sources of mail can be either "mail sources" or select methods. Mail
sources will move mail to ~/Mail (not sure what format), and split it into groups according to variables. You can use
"mail sources" for maildir / imap, but those can also be read via select methods, which do not move the mail from their
location, but use them in their native format. This is what I want to do, and I can simply ignore mail
sources. Confusing terminology is that "fetching mail" "scanning mail", lots of things mail doesn't mean all mail, it
means specifically from "mail sources". The words "articles" and "news" is used in connection with select methods, aka my actual mail.



** caching background

caching:
there is also ~/News/cache, filled with a bunch of articles, like 300 megs. can't figure out why.
Grepped for caching in the manual, found 2 main things.
cache is for 2 purposes. to cache locally, and to keep articles from expiring, called persistence
gnus-use-cache, which puts things if they are
gnus-cache-enter-articles
things go in cache when they are marked certain ways by default, ticked and dormant
and read articles are moved out of the cache
still no idea why i have a bunch in the cache, but I set a var so that my mail won't get cached
I'm gonna delete the cache, and check on it later see what exactly is going in there
And of course, I moved ~/News to my encrypted drive and symlinked it

google turned up: http://lists.gnu.org/archive/html/help-gnu-emacs/2014-03/msg00544.html
the xresource doesn't work for me, probably an xmonad thing.

figured out I needed to customize the header line face. To find the face, M-x list-faces-display or just google / search
info,
then M-x customize-face
header-line
unchecked some stuff so that it inherits from default.

** prefix keybind changes
#+begin_src emacs-lisp


  ; prefix key binds.
  ; good info http://www.masteringemacs.org/articles/2011/02/08/mastering-key-bindings-emacs/
  ; rebinding the prefix keys are tricky. apparently, some modes ignore any redefinition of a prefix key and use it explicitly,
  ; so you have to dig into their key maps and redo things.
  ; There are 2 simpler alternatives which have their own downsides.
  ; One is cua mode, which I do not like because it smashes 2 keybinds onto 1 and limits what you can do.
  ; The other is keyboard-translate, which translates the key presses before anything else.
  ; The downside is that it translates them when you aren't using them as a prefix.
  ; Since the swaps I'm using are all very accessible, the only downside is some mental jugling when reading docs etc about these keybinds.

  ; I've seen this as an another suggestion, it was a total fail. The prefix command took over both keys.
  ; (define-key key-translation-map [f12] "\C-c")
  ; (define-key key-translation-map "\C-c" [left])


  ;idea to remove the hook later since it is only needed at startup.

This needs to be at the end, because I visit a file, thus setting a
mode, and the mode hook needs to be setup before that.

I'm using persistent registers instead of bookmarks. I dun use them
much, so the added hassle of having to set it within this file is
worth the benefit of only having one concept in my mind.

** initial python-mode setup

python-mode seems to be the most canonical package, based on
https://docs.python.org/devguide/emacs.html
much more feature rich than the emacs built in one.

getting it, it wants you to setup an account on launchpad by default,
there is some way to get anonymous bzr access, but google didn't answer it right away,
so fuck it, ill go the happy path.

based on error messages,
add public ssh key to https://launchpad.net/people/+me
bzr launchpad-login iank
cd  ~/.emacs.d/src/
bzr branch lp:python-mode

add lines from INSTALL to init


** background on packages
jedi appears most popular based on github stats
pysmell appears dead
ac-python appears dead
https://github.com/proofit404/anaconda-mode seems to be kicking along


** misc notes:

python-mode has a TON of functions that are just aliases or verbatim wrappers of other functions.
also has undocumented/unused vars all around. it is quite annoying.

the dedicated argument to py-shell does nothing,
and py-dedicated-shell just sets that, so it is a waste


** background on sending to python shell

using the builtin python execute shell functions, sending one line doesn't really work well.
The bulit in functions don't wait for further input if a block is not closed.
And doing a copy/paste thing gets messed up because of indents.
With some hacking, I could probably do copy/paste and remove indents, only to a
certain level if we have entered a block and are waiting to finish it.
But just doing the builtin execute block is a decent work around.


Here is the scrapped function for single line built in sending to shell.
