Configuration
-------------

All settings can be shown and set using eesh.

To get a full list of settings:
$ eesh show

To set some parameter:
$ eesh set <parameter> <value>
Some settings will not be effective until E is restarted.

To get a list of all eesh commands:
$ eesh help full

Configuration files
-------------------
Skip this section unless you *really* want to know...

It is here assumed that --prefix is /usr, and that the default user
configuration directory (~/.e16) is used.

In general, the configuration search order for theme related configuration
files, say xyz.cfg, is:
1) User configuration directory, i.e. ~/.e16/xyz.cfg.
2) Theme directory, i.e. /usr/share/e16/themes/<theme>/xyz.cfg, or
   ~/.e16/themes/<theme>/xyz.cfg.
3) Default configuration directory, i.e. /usr/share/e16/config/xyz.cfg.

Mouse and keybindings are defined in bindings.cfg. bindings.cfg is searched in
1) User configuration directory, i.e. ~/.e16/bindings.cfg.
2) Default configuration directory, i.e. /usr/share/e16/config/bindings.cfg.

Window matches (border and icon associations) are defined in windowmatches.cfg
and matches.cfg.
windowmatches.cfg (deprecated, border associations only) is loaded first,
and should be found only in theme directories.
matches.cfg is loaded next, and searched in
1) User configuration directory, i.e. ~/.e16/matches.cfg.
2) Default configuration directory, i.e. /usr/share/e16/config/matches.cfg.
Window match items are appended to the window match list, in the order
in which they are read from the configuration files.
When doing border/icon matches, the window match list is searched from the
start, and the first matching item will be used.

Session Scripts
---------------
Enlightenment can now automatically run user scripts or applications during
Startup, Restart, and Shutdown. This facilitates the loading of system
tray applets, rss readers, screensavers, and other daemons (e.g. dbus),
and allows for cleanup of programs that don't terminate properly when E
quits (this is especially common with KDE applications in E and the arts
daemon or dcop server keeps running).

Enlightenment accomplishes this with the addition of two new keys in
the $ECONFDIR/e_config--#.#.cfg (#.# may vary depending on your X setup -- 
for most people, it will be 0.0). These are:

misc.session.enable_script 
misc.session.script 

misc.session.enable_script is a boolean. When set to 1, Enlightenment will 
execute the script in the misc.session.script key. By default, this feature 
is disabled. When enabled, it will do nothing until the user configures
his/her home directory ($ECONFDIR -- normally ~/.e16).

The default session.script is located in $EROOT/scripts/session.sh ($EROOT
is normally /usr/share/e16 or /usr/local/share/e16). It will look for 
directories in the user's $ECONFDIR/ (~/.e16/) called:

~/.e16/ ($ECONFDIR)
	Init/
	Start/
	Stop/

and run any and/or all scripts or executables in each when E starts, 
restarts, and shuts down. If no scripts or executables are present, or
if any of the directories Init, Start, and Stop do not exist, NOTHING
will happen and E will start up as usual. So, in order to use session
scripts, all the user has to do is to populate the Init, Start, and Stop
directories with scripts, applications, or links to applications that
should run during Startup, Restart, or when E is stopped.

The default values for the new keys are:

misc.session.enable_script = 0
misc.session.script = $EROOT/scripts/session.sh

The user may write a custom script and place it anywhere. Simply modify 
the config file by using:

$ eesh set misc.session.script myscript

and modify it (be sure to chmod +x the file otherwise it won't run). 
The session script is called with one of three command parameters; 
init, start, and stop. Any custom script should have a code block 
similar to this in order to function properly in Enlightenment.

case "$1" in
init)
        # do blah
        # or do function init
start)
        # do blah
        # of do function start
stop)
        # do blah
        # or do function stop
esac

Automatic script running can be enabled/disabled via the Session Settings
dialog in Enlightenment and checking/unchecking the option Enable Session
Script, by editing the user cfg file and setting the
misc.session.enable_script key to 1/0, or with

$ eesh set misc.session.enable_script 1/0

This process is very flexible since when used, the user can turn off
individual scripts and applications by chmod -x or simply leave the
startup directories empty or remove them.


Composite manager notes
-----------------------

To use the composite manager it is required that the X-server has support
enabled for the COMPOSITE, DAMAGE, FIXES, and RENDER extensions.
For reasonable performance it is also required that hardware acceleration
of the RENDER extension is enabled.

As of version 0.16.8.2 it may happen that the borders on application windows
using ARGB visuals (for transparency) are "ugly". Applications may use ARGB
visuals intentionally (e.g. fdclock) or not (e.g. xv on 16 bit root depth).
Applications unintentionally using an ARGB visual will normally not be
rendered properly at all and should be started with the environment variable
XLIB_SKIP_ARGB_VISUALS set.
To fix border rendering on "real" ARGB windows it is required to use imlib2
with version >= 1.3.0.

Tweaks:

As of e16 >= 0.16.8.9: If there is any kind of trouble with the composite
manager, first check compmgr.mode (eesh show compmgr), and set it to 1 if
it isn't (eesh set compmgr.mode 1, restart).

If pop-up windows disappear immediately after having appeared (may happen
e.g. with certain pop-up windows when using gnome > 2.12), try:
$ eesh set compmgr.override_redirect.mode 0
This should make the pop-up windows usable, but not always rendered properly.
This problem should not occur with recent X-servers.

If window resize/shading with composite enabled is ugly, try:
$ eesh set compmgr.resize_fix_enable 1
This problem should not occur with recent X-servers.


Fonts
-----
Theme font selection depends on a number of settings and whether or not
the theme has font alias support.

For themes with font alias support the fonts are determined by a font
configuration file. This file is selected as follows, first hit applies:

- If theme.use_alt_font_cfg is set (default off) and the the file specified
  by theme.font_cfg is found the fonts are determined by this file.

- If theme.use_theme_font_cfg is set (default off) and the theme has a
  fonts.theme.cfg the fonts are determined by the theme's fonts.theme.cfg.

- If e16 was built with pango support, look for fonts.pango.cfg.

- If e16 was built with xft support, look for fonts.xft.cfg.

- Look for fonts.cfg.

The font configuration file search path is ~/.e16, <theme-dir>, and
/usr/share/e16/config.
Default fonts.pango.cfg and fonts.xft.cfg are provided in /usr/share/e16/config.

The default theme (winter) and the core themes (BlueSteel, BrushedMetal-Tigert,
Ganymede, and ShinyMetal) do have font alias support.

Don Harrop has made available a major number of e16 themes which have been
modified for font alias support (http://themes.effx.us).

Other themes are likely to not have font alias support but in stead have font
references more or less scattered around in TextClass definitions in the theme
configuration files.

There are several ways to specify a font (in the font configuration file or
in TextClasses):

- "<font name>/<size>", e.g. "Vera/8".
  In this case e16 must be able to find "Vera.ttf" in <theme dir>/ttfonts or
  /usr/share/e16/fonts.

- XLFD font sets, e.g. "-*-lucida-medium-r-normal-*-12-120-*-*-*-*-*-*,-*-gulim*-medium-r-normal-*-12-120-*-*-*-*-ksc5601.1987-*".
  xfontsel, xlsfonts, and xfd can be used to select and show these fonts.

- Fontconfig font names, prefixed by "xft:", e.g. "xft:Luxi Sans-10:bold".
  fc-list and xfd can be used to select and show these fonts.
  This possibility (Xft support) is available as of version 0.16.8.5.

- Pango font names, prefixed by "pango:", e.g. "pango:sans bold 10".
  This possibility (Pango support) is available as of version 0.16.8.9.
  Pango support must be explicitly enabled at build time with --enable-pango.


Using e16 with GNOME
--------------------
Setting up e16 as WM in a GNOME session unfortunately depends on the version
of gnome-session.

Recent versions of gnome-session seem to require that a gconf key is set
and that an e16.desktop file can be found:

$ gconftool-2 --set /desktop/gnome/session/required_components/windowmanager --type string e16
$ gnome-sesssion

/usr/share/applications/e16.desktop (or ~/.local/share/applications/e16.desktop):
[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=E16
Comment=The Enlightenment (e16) window manager
Exec=e16
Icon=/usr/share/e16/misc/e16.png


The section below seems to be obsolete as of gnome-session-2.2x(?)

The GNOME desktop can be started using e16 as WM with:

$ export WINDOW_MANAGER=e16
$ gnome-sesssion


The section below is obsolete as of gnome-session-2.16

However, somewhere along the way the script /usr/bin/gnome-wm is called.
This is supposed to handle differences in all the different WM's out there,
but does not know of "e16". This will cause a major delay when starting up
the GNOME desktop.
One way to fix this is to use gnome-session-properties to get rid of
the "gnome-wm" session entry.
Another is to apply this patch to /usr/bin/gnome-wm:

The following sections are only relevant for users upgrading from version 0.16.7
or older.

Changes:
- "enlightenment" has been renamed to "e16".
- The default user configuration directory is "~/.e16".
- The data install path is "<somepath>/e16", e.g. "/usr/share/e16".
Thus, an e16.8 installation should not clash with any other versions.
- Various configuration file formats have changed and should be easier
  to read and modify, if needed.
- The configuration is stored per display and per screen.  E.g. for
  DISPLAY=:1.0 the main configuration file is "~/.e16/e_config--1.0.cfg".
- Actions(used by menus, keybindings, etc.) and IPC functions(eesh) have
  been merged.
- Many IPC(eesh) commands have been changed, possibly breaking compatibility
  with a few epplets.
- Window matches and icondefs have been merged (into matches.cfg), see below.

New features:
- Built-in composite manager.
- An iconbox can be configured to act as System Tray
  (middle mouse->Desktop->Create Systray).
- Possibility to run programs on startup, restart, and shutdown, see
  "Session Scripts" below.
- Possibility to track changes in remembered settings.
- Window operations by window matches (class, name, transient, ...),
  e.g. for making all windows of a certain type sticky, put it on a certain
  layer, etc. (see matches.cfg).

0.16.8 should be compatible with most e16 themes. However, user installed
themes will have to be moved/linked to ~/.e16/themes/ or <datadir>/e16/themes/.
A few themes will have to be tweaked to work with e16.8. The most likely
problem is that configuration settings are included in .cfg files where they
are no longer accepted.
See the "Migrating ..." section below for additional information.

e16keyedit >= 0.3 works with e16.8.
If used to change the keybindings, the modified settings will be stored in
~/.e16/bindings.cfg.
It should also be fairly straightforward to modify the key- and buttonbindings
by hand. Copy /usr/share/e16/config/bindings.cfg to ~/.e16/bindings.cfg and
modify as desired.
NB! e16keyedit only modifies keybindings, not buttonbindings.

NB!!! Do not rename ~/.enlightenment to ~/.e16. It will only cause trouble.

Migrating from versions older than 0.16.8
-----------------------------------------

Users upgrading from enlightenment 0.16.7 need to read the following.

Several organizational changes have occurred that will require
some manual adjustments. Mainly these deal with changes to 
configuration and shared directory names. This was done to avoid
collisions with the new enlightenment DR17.

1) home configuration directory is now ~/.e16, not ~/.enlightenment.
2) menu files have been moved to a subdirectory called menus
   you will need to move customized menus and subdirectories to
   ~/.e16/menus.
3) you will need to move ~/.enlightenment/backgrounds files to ~/.e16
   and any themes as well.
4) $prefix/share/enlightenment has been changed to $prefix/share/e16
5) if installed E-docs and Epplet directories will have to be moved 
   to $prefix/share/e16
6) any additional themes that were added to the $prefix/share/enlightenment
   directory will have to be moved to $prefix/share/e16
7) any startup scripts or Session scripts that reference the startup
   executable `enlightenment` must be edited to the new e16 program.


A few themes have to be tweaked to work with 0.16.8.

Some themes (Maw, Black E) have an actionclasses.cfg like:

#include <definitions>
__E_CFG_VERSION 0
#include </usr/local/enlightenment/config/actionclasses.cfg>
#include </usr/share/enlightenment/config/actionclasses.cfg>

The absolute path is obviously no longer valid.
The most sensible fix for these themes is to remove the themes
actionclasses.cfg. e16 will then fall back to the default one.
