* TODO Tasks that need attention
** TODO BUG!!!!!!!!!!!! invalid target location, and the capture is gone.
** TODO C-a does not work as expected when the subtree is expanded
** TODO migrate from patching org-mode to a more sustainable option
the issue is that I wanted to make sure that nothing would break by
managing conflicts by hand, but this is not happening in practice
** TODO can we run a task with an org-link?
For instance, I want to call kmail in "zero inbox proton"
** DONE improve helm-mu-contacs
- [ ] Manage ignore list
We can advise ~ helm-mu-contacts-transformer~ and remove the
candidates
- [ ] Implement action for ignoring contacts
** TODO remove duplicates in contacts list with double spaces and such
** DONE take care of the "dear To" when completing the name in an email
** DONE make an alist for names to nicknames when completing the name…
** TODO how to "open with" attachments with mu4e?
** DONE investigate what is wrong with inline-pdf image width
I need to cycle the mode on/off to make it work as intended
** TODO fix the issue with highlighting bleeding over the margin for
~ace-window~
** TODO The window management is sometimes frustrating
** TODO Autosort token for some subtrees
** TODO Work on a "welcome" read-only org page for each activity in
which we put links to what should be done in that activity. For
instance
** TODO revert org-files on frame activation.
What was the deal with auto-revert-mode again?
** TODO explore [[https://blog.modelworks.ch/managing-papers-with-org-mode-and-reftex/][this possibility]] about org-mode paper managing
* COMMENT About indentation in this file
This file will be indented with ~org-adapt-indentation~ set to t
* TODO Look at tangling at
[http://thewanderingcoder.com/2015/02/literate-emacs-configuration/]
although I'd rather do something like a local variable evaluation such as
# -*- eval: (add-hook 'before-save-hook icalendar-export-to-ics nil t) -*-
Or makefile approach
[https://emacs.stackexchange.com/questions/27126/is-it-possible-to-org-bable-tangle-an-org-file-from-the-command-line]
See also [http://orgmode.org/manual/Extracting-source-code.html#Extracting-source-code]
* About org-mode
I am insisting to use my own branch of org-mode; in order to have
this work, we need to run the following code before
anything else. Add it to ~early-init.el~. This file is tangled
every time emacs starts, so that's fine.
#+begin_src emacs-lisp :tangle "early-init.el"
; this is required for using my branch of org-mode
(add-to-list 'load-path "~/clones/org-mode/lisp")
(require 'org-loaddefs)
#+end_src
* Introduction
** ~setq~ vs ~setq-default~
Some variables are local, others are not; for non buffer-local
variables the two commands are equivalent; for the buffer-local variables,
setq acts on the current buffer, whereas setq-default sets the default
value of the variable for buffers that do not have a local value.
:source: [https://stackoverflow.com/a/18173666]
** Why not ~package.el~
it is convenient, but it is not git-based; ~borg.el~ is promising, but it is
way complicated; I can do everything by hand as soon as it is neatly
~org~-anized. In the end we use a few, but I plan to phase them out and
replace them with git submodules
* Files and dirs
Move ~Customize~ to a separate file
#+begin_src emacs-lisp
(setq custom-file "~/.emacs.d/custom.el")
(load custom-file 'noerror)
#+end_src
Add relevant dirs to load path [This is somewhat undesirable; I should
uniformize the path-loading business at some point…]
#+begin_src emacs-lisp
(let ((default-directory "~/.emacs.d/"))
(normal-top-level-add-subdirs-to-load-path)
(normal-top-level-add-to-load-path '("biblio.el"
"fringe-helper.el"
"multiple-cursors.el"
"expand-region.el"
"dash.el"
"webpaste.el"
"highlight-parentheses.el")))
#+end_src
Put autosave files (ie #foo#) and backup files (ie foo~) in ~/.emacs.d/.
create the autosave dir if necessary, since emacs won't.
#+begin_src emacs-lisp
(make-directory "~/.emacs.d/autosaves/" t)
(make-directory "~/.emacs.d/backup/" t)
#+end_src
* Themes
Use (my clone of) the solarized theme
#+begin_src emacs-lisp
(add-to-list 'custom-theme-load-path "/home/jacopods/.emacs.d/emacs-color-theme-solarized")
(load-theme 'lunarized t)
#+end_src
Use patched terminus font (this overrides the settings in Customize,
but I never could it work otherwise). See the special treatment
later on for dealing with bold weight. To avoid flickering one
should also set the font in .Xresources
#+begin_src emacs-lisp
(set-face-font 'default "Hackminus")
(set-face-font 'fixed-pitch "Hackminus")
(set-face-font 'fixed-pitch-serif "Hackminus")
(set-face-font 'variable-pitch "Hackminus")
#+end_src
* Global settings
** server name
I prefer to keep one server for each KDE activity, so
set the server name to be the name of the current activity
#+begin_src emacs-lisp
; (setq server-name (kde-current-activity-name))
#+end_src
** Global helper functions
This is a helper function used to set several global keys given in
provided as a parameter in ~binding-alist~
#+begin_src emacs-lisp
(defun global-set-key-alist (binding-alist)
"This function iterates over the binding-alist, which should be an alist of key and binding and sets each binding in the global-key-map"
(dolist (binding binding-alist)
(global-set-key (kbd (car binding)) (cdr binding))))
(defun define-key-alist (keymap binding-alist)
"This function iterates over the binding-alist, which should be an alist of key and binding and sets each binding in the global-key-map"
(dolist (binding binding-alist)
(define-key keymap (kbd (car binding)) (cdr binding))))
#+end_src
This is a hack to remove slant and bold from all faces
#+begin_src emacs-lisp

(set-face-font 'default "Hackminus"))
#+end_src
This function saves the current buffer after the specified amount
of idle time, unless something calls it again and then the timer
restarts
#+begin_src emacs-lisp
(defun save--buffer-buf (buf)
(with-current-buffer buf (save-buffer)))

*** Source blocks
Add template for a source block in a few selected languages; for
now I have
- emacs-lisp
- shell
. This is useful for writing the emacs init file in literate form,
or dotfiles for other code. Since Org 9.2, the behavior that I
grew accustomed to (e.g. ~<el TAB~) )is implemented by ~org-tempo~, so I need to require that as well.

** Fixup faces
This is really a workaround as I do not like either bold or italic.
It needs to be at the end of the file since it sets the face for
packages that have loaded in the meantime; yet it does not work
perfectly as some packages are still to be loaded (most notably ~magit~)
