This removes code duplication, which will be useful for a subsequent
commit.
Furthermore, we now don’t open X11 connections unnecessarily in some
corner cases.
Add DRAG_ABORT to enum drag_result_t. DRAG_ABORT will indicate the drag
operation cannot be completed.
Return DRAG_ABORT on UnmapNotify, or when the keyboard or pointer cannot
be grabbed.
Add DRAGGING to return value for drag_result_t. DRAGGING is used
internally by drag_pointer to indicate the drag is in progress.
Change DRAG_CANCEL to DRAG_REVERT to clarify the distinction between
"abort" and "revert/cancel" actions.
Fixes an issue that caused i3 to crash when a user is dragging or
resizing a floating window that becomes destroyed.
i3 current behavior hides the binding mode indicator when
workspace buttons are disabled.
This patch adds a new configuration for i3bar called
'binding_mode_indicator' which acts like the workspace_buttons.
It is now possible to configure i3bar to hide the
workspace buttons and keep showing the binding mode indicator.
This should make the hide workspace buttons configuration
more convenient for those who are heavily using binding
modes.
Default value for binding_mode_indicator is true.
This reverts commit 0659a0d98c.
It was a fix for dzen2 setups, but broke several other use cases.
Because dzen2 is not really important since most people use i3bar
nowadays, let’s revert this.

This ClientMessage can be used to estimate how big the window will be
before opening it. Java always sends the ClientMessage and checks the
atom that should be set by the window manager, but it seems that the
fallback code path has a race condition.
Let’s see if the situation gets better with this change. I have been
running this patch for about two weeks and have not seen any issues with
it.

Add debuglog command that takes toggle|on|off. Add get_debug_logging()
to be able to toggle. Make t/187-commands-parser.t expect 'debuglog'.
Document the debuglog command in userguide.
This commit only goes to “next” because I am not sure whether it
actually makes things better in all cases and want to give it some
testing first.
There was no documented reason behind using the
proportional_{width,height} variables, so I suppose that code was just
stupidity on my part (it was written merely a month after I started this
project in 2009).
fixes#1032
Add shmlog command that takes <size>|toggle|on|off. Separate logbuffer
management into open_logbuffer() and close_logbuffer(). Make
t/187-commands-parser.t expect 'shmlog'. Add update_shmlog_atom() to
update the SHMLOG_PATH. Document the shmlog command in userguide.
The hidden_state and mode of each i3bar instance can now be controlled from within i3.
Therefore, two new i3 command were introduced:
_
bar hidden_state show|hide|toggle [<bar_id>]
show: always show the bar
hide: normal hide mode
toggle: toggle between show and hide (individually for each bar)
_
bar mode dock|hide|invisible|toggle [<bar_id>]
hide,dock: like before
invisible: always keep the bar hidden
toggle: toggle between dock and hide (individually for each bar)
This patch introduces a hidden_state ("hidden_state hide|show") in the
barconfig, which indicates the current hidden_state of each i3bar
instance. It only affects the bar when in hide mode. Additionally, a new
invisible mode was introduced. In order to change the hidden_state or
mode of the bar from i3, a barconfig-update event was introduced, for
which a bar can subscribe and the bar then gets notified about the
currently set hidden_state and mode in its barconfig.
For convenience, an id field ("id <bar_id>") was added to the barconfig, where one can
set the desired id for the corresponding bar. If the id is not specified, i3 will
deterministically choose an id; otherwise, with the previous random approach for finding
a new id, which is actually not shared with i3bar, as it would determine its id on
startup, the event-subscription would be destroyed on reload. Still, this issue remains
when manually changing the bar_id in the config and then reloading.
fixes#833, #651
In order to distinguish split layouts from tabbed/stacking layouts when
only one window is shown, do not draw the indicator border for tabbed or
stacking layouts.
Note that this is ineffective for dunst’s notifications because dunst
re-raises them as soon as they get obscured. It does work for dzen2
however, which was the original use-case.
fixes#569
What I do in this patch is:
1. Split the con_new() function, so I can create a Con without actually
create a window.
2. Store the depth of Cons in the layout file when i3 is restarting.
Fix typos and mis-staged files in previous patch.
_NET_WM_STATE_DEMANDS_ATTENTION indicates that some action in or with
the window happened. It's a weaker hint than urgency flag of WM_HINTS,
but some applications and almost all Qt applications use it instead of
WM_HINTS' urgency flag (one example is Skype).
Added new event id (I3_IPC_EVENT_WINDOW) so that a an IPC client can
subscribe to events on windows. Added a basic window event that gets
triggered when a window gets successfully reparented. This new event
also dumps the container data, so that IPC clients can get the initial
window name. IPC clients wishing to see window events should subscribe
to 'window'.
This patch adds the following features:
1) Configure a color of the separator via config. It is done like
bar {
colors {
separator #000000
}
}
2) A block can have an integer entry "separator_block_width" which
sets the width of the gap which would follow after the current block.
3) A block can have a boolean entry "separator" and if it is set
to false, then the drawing of the separating line would be disabled.
This change ensures a scratchpad window is still centered on the screen
if it has first been shown on another screen of a different
resolution. Moving or resizing the scratchpad manually disables this
behavior.
• our function names use underscores
• rewrote the function’s comment
• function comments must be in the source _and_ in the header
• no blank lines after function signatures
With this commit, the default behavior is to display popups while there
is a fullscreen application only if the popup belongs to that
application (as determined by the WM_TRANSIENT_FOR hint which
applications have to set properly).
fixes#663
If a window with _NET_STARTUP_ID set is moved to another workspace, it
will delete any associated startup sequence immediately. This will also
occur if a window has a leader with _NET_STARTUP_ID set, if the leader
has no container (never been mapped).
A startup sequence may also be deleted if it's matched by
startup_workspace_for_window() and its 30-second timeout has elapsed.
A good visualization of the new algorithm is this:
+--------+
| |
+--------+=| S1 |========================
| | | |
| S0 | +--------+
| | +--------+
+--------+=========| |================
| S2 | +--------+
| | | |
+--------+ | S3 |
| |
+--------+
When focus is on S0, 'focus output right' will first match S1 (the
closest output which overlaps in the highlighted area), then S2, but not
S3 (since S3 does not overlap into the highlighted area).
fixes#669fixes#771
If there is a client with an urgency hint on another workspace and
switching to this workspace would cause the urgency to be reset (by
moving the focusing to the client), delay the reset by some time. This
gives the user the chance to see it.
This commit adds the possibility to configure the urgency delay timer
duration using the 'force_display_urgency_hint' directive. Also,
documentation and a testcase was added to allow for automated checks of
the intended behavior.
fixes#482
this implements both the "move container to workspace back_and_forth" command
and movements to the same workspace when auto_back_and_forth is set.
it includes documentation and test suite additions by michael.
it also simplifies the workspace_show_by_name function (making use of
workspace_get accepting NULL pointers).
Introducing a new event to subscribe called mode. It's fired up
when i3 changes binding mode (like switching from default to resize).
IPC guide adjusted also.
Before commit 4976fa3350, setting the
layout of workspaces to something else than the default would just mess
up the parent container of the workspace (the content container).
After that commit, it would create an unnecessary split container when
you change the layout _before_ opening any containers. To avoid this, we
now store the layout (similar to how the 'workspace_layout'
configuration directive works) and apply it when the first container is
attached to the workspace.
Fixes#796
For the following binding:
# Simulate ctrl+v upon pressing $mod+x
bindsym --release $mod+x exec --no-startup-id xdotool key --clearmodifiers ctrl+v
you can now use either:
1. press $mod, press x, release x, release $mod
2. press $mod, press x, release $mod, release x
fixes#485
The implementation is naive because the user has to generate exactly the
event he specified. That is, if you use this binding:
bindsym --release $mod+x exec import /tmp/latest-screenshot.png
Then it will only be triggered if you hit $mod, hit x, release x,
release $mod. It will not be triggered if you hit $mod, hit x, release
$mod, release x. The reason is that the KeyRelease event in the latter
case will not have the modifier in its flags, so it doesn’t match the
configured binding.
This changes the fact that Firefox would not be launched on the correct
workspace because it marked the startup sequence as completed *before*
actually mapping all of its windows.
To test this, go to workspace 3 and run this command in a terminal:
i3-msg 'exec iceweasel; workspace 4'
That will make i3 start iceweasel (and create a proper startup
notification context for it), then immediately switch to workspace 4
(before iceweasel could possibly start).
The iceweasel window(s) should appear on workspace 3.
While this is a bit ugly, it makes the log messages end up where they
are supposed to: in the shmlog/stdout in case of i3 and on stdout in
case of utilities such as i3-input
This changes the SHM log format, it doesn’t use 0-bytes to separate
entries anymore. Instead of using lots of printf() calls in i3-dump-log,
we now do precisely one big write().
So, to be clear: i3-dump-log and i3 both need to be upgraded.
Mismatching versions will lead to garbage output (no crashes of i3, just
garbage output).
The -f flag uses an inter-process pthread_cond_t in the shared memory
header to broadcast the arrival of new messages to all i3-dump-log
processes. This internally uses futexes and thus doesn’t even mean a
kernel call in most cases. inter-process pthread_cond_ts require NPTL
(the Native Posix Thread Library, introduce in Linux 2.6).
From the source:
When starting i3 initially (and after each change to the connected
outputs), this function fixes the resolution of the __i3
pseudo-output. When that resolution is not set to a function which
shares a common divisor with every active output’s resolution,
floating point calculation errors will lead to the scratchpad window
moving when shown repeatedly.
fixes#632
This is useful for third-party scripts which require certain features
and want to error out cleanly when they are run with an old i3 version.
Additionally, i3 --version might be different from what’s actually
running (an old version of the binary), so i3-msg -t get_version will be
the best way to figure out the i3 version you are actually running from
this commit on.
With this commit, the "default" layout is replaced by the splith and
splitv layouts. splith is equivalent to default with orientation
horizontal and splitv is equivalent to default with orientation
vertical.
The "split h" and "split v" commands continue to work as before, they
split the current container and you will end up in a split container
with layout splith (after "split h") or splitv (after "split v").
To change a splith container into a splitv container, use either "layout
splitv" or "layout toggle split". The latter command is used in the
default config as mod+l (previously "layout default"). In case you have
"layout default" in your config file, it is recommended to just replace
it by "layout toggle split", which will work as "layout default" did
before when pressing it once, but toggle between horizontal/vertical
when pressing it repeatedly.
The rationale behind this commit is that it’s cleaner to have all
parameters that influence how windows are rendered in the layout itself
rather than having a special parameter in combination with only one
layout. This enables us to change existing split containers in all cases
without breaking existing features (see ticket #464). Also, users should
feel more confident about whether they are actually splitting or just
changing an existing split container now.
As a nice side-effect, this commit brings back the "layout toggle"
feature we once had in i3 version 3 (see the userguide).
AFAIK, it is safe to use in-place restart to upgrade into versions
after this commit (switching to an older version will break your layout,
though).
Fixes#464
e.g. pressing Mod1+x when having the following in your configfile:
bindsym Mod1+x some invalid command
will lead to an i3-nagbar instance popping up, offering you to view the
error log (which will contain parser errors from this commit on).
This is now restricted according to the already defined fullscreen
focus constraints. Test case 157 was removed, as we don't prevent
level up/down in fullscreen anymore. Those commands are properly
tested in fullscreen by test case 156.
Fixes: #612
Basically, a focus change can't escape a fullscreen container. The
only exception is per-output fullscreen containers, as you should
be able to focus a container in a different workspace in this case.
This is an improvement on 4eab046e, now considering the difference
between global and per-output fullscreen and taking the tree
structure into account to determine what escaping the fullscreen
container means. It only affects targeted focus commands in the
form "for_window [...] focus", but it lays the foundation for
forthcoming fixes to all other focus commands.

The C compiler will handle (void) as "no arguments" and () as "variadic
function" (equivalent to (...)) which might lead to subtle errors, such
as the one which was fixed with commit 0ea64ae4.
Initially I thought using the second precision time() function is good enough,
but to make t/113-urgent.t considerably faster (>2s vs. 0.08s), we put in a
little more effort and use gettimeofday. Otherwise, this test blocks the whole
testsuite from completing much faster on modern machines :).
This change has two implications:
1) tree_render() will now be called precisely once for input which consists of
multiple commands (like "focus left; focus right"). Also, the caller of
parse_command() has to call it. This makes us able to fix tickets such as
ticket #608 (where multiple tree_render() calls are noticable).
2) The output of a command is now a JSON array of return values of the
individual subcommands. In the case of "focus left; focus right", this is:
[{"success":true}, {"success":true}]
While this is incompatible with what i3 returned before, the return value of
commands was undocumented and therefore not subject to our API stability.
You need to specify the --enable-32bit-visual flag when starting i3. This is
done because everything feels sluggish on my system when using a 32 bit visual
instead of a 24 bit visual. Fast > fancy.
Currently it supports the following options:
"oldest": match the first window that triggered an urgent event
"latest": match the last window that triggered an urgent event
This re-introduces borders around the workspace buttons in i3bar.
No additional pixels will be consumed (you will not lose any space for your
windows).
On the rationale of using a custom parser instead of a lex/yacc one, see this
quote from src/commands_parser.c:
We use a hand-written parser instead of lex/yacc because our commands are
easy for humans, not for computers. Thus, it’s quite hard to specify a
context-free grammar for the commands. A PEG grammar would be easier, but
there’s downsides to every PEG parser generator I have come accross so far.
This parser is basically a state machine which looks for literals or strings
and can push either on a stack. After identifying a literal or string, it
will either transition to the current state, to a different state, or call a
function (like cmd_move()).
Special care has been taken that error messages are useful and the code is
well testable (when compiled with -DTEST_PARSER it will output to stdout
instead of actually calling any function).
During the migration phase (I plan to completely switch to this parser before
4.2 will be released), the new parser will parse every command you send to
i3 and save the resulting call stack. Then, the old parser will parse your
input and actually execute the commands. Afterwards, both call stacks will be
compared and any differences will be logged.
The new parser works with 100% of the test suite and produces identical call
stacks.
After a reload, the drawing parameters for the decorations might
have changed, so we need to invalidate the cache and force a redraw
of the currently visible decorations. Also, don't leak the previous
font when reloading by freeing it before parsing the config.
Abstracted draw_text and predict_text_width into libi3. Use
predict_text_width from libi3 in i3 too. This required tracking
xcb_connection in a xcb_connection_t *conn variable that libi3
expects to be available in i3bar.
Also prints out useful stuff:
CORE DUMPS: You are running a development version of i3, so coredumps were
automatically enabled (ulimit -c unlimited).
CORE DUMPS: Your current working directory is "/home/michael/i3".
CORE DUMPS: Your core_pattern is: /tmp/%e.core.%p
i3 (tree) version 4.0.2-479-g26ab2ac (2011-11-08, branch "next") starting
This does not affect child processes of i3.
The intention of this change is to make debugging easier – it’s one less thing
users of the development version have to worry about when trying to help with
debugging.
Also, the API changed a bit. There are two functions now, both assume you
already got the keysyms (which is the case for i3 and i3-config-wizard),
one gets the modifier mapping for you (aio_get_mod_mask_for) while the other
assumes you also got that. No roundtrips are required for the latter.
In order to not depend on X11 just for getting the socket paths, scripts or
other programs can now use i3 --get-socketpath. Since i3 must be present on the
computer anyways, this saves one dependency :).
This is mainly useful for the testsuite. The tests can wait until i3 processed
all X11 events and then continue. This eliminates sleep() calls which leads to
a more robust and faster testsuite.
The configuration option does the same as the commandline parameter, except
it can be easily set by the user (e.g. you are using KDM and can't start a
session through ~/.xsession).

- Introduce warp_to static variable in x.c that stores the coordinates
to warp to as a Rect.
- Add x_set_warp_to function to set this variable. Use in _tree_next,
workspace_show, and con_move_to_workspace.
- In x_push_chanages, if warp_to is set, then call xcb_warp_pointer_rect
and then reset it to NULL.
This fixes all know bugs for pointer warping for me.
Modify _tree_next() so that when we reach the workspace container:
1. Find the next corresponding output (screen) using the added
get_output_next().
2. If there is another output, find the visible workspace.
3. Call workspace_show on found workspace.
4. Find the appropriate window to focus (leftmost/rightmost, etc.) using
con_descend_direction, and then focus it.
I've only tested on horizontal monitors (left/right).
Generally, the traversal goes: numbered workspaces in order, and then
named workspaces in the order in which they appear in the tree.
Example:
Output 1: Output 2:
1 3 D C 2 4 B A
Traversal: 1, 2, 3, 4, D, C, B, A, 1, ...
Note, after the numbered workspaces, we traverse the named workspaces
from output 1, and then output 2, etc.
This fixes a race where we created cursors on the Xlib connection, flushed,
then used the cursor on the XCB connection. Even though we flushed, the X
server did not process the requests yet and therefore returned a BadCursor
error.
This bugfix uses the Xlib connection for setting the root window cursor which
will ensure that the requests are properly serialized.
An easy test for this (on my machine) is the following ~/.xsession:
xsetroot -cursor_name cross
exec i3
If you see a cross cursor instead of the pointer, the race happens. You’ll see
a error_code=6 error in your ~/.xsession-errors.
These errors can happen because a DestroyWindow request by a client will
trigger an UnmapNotify, then a DestroyNotify. We cannot distinguish this
UnmapNotify from an UnmapNotify not followed by a DestroyNotify, so we just try
to send the ReparentWindow / ChangeProperty and ignore the errors, if any.
Think of the following layout:
-------------
| tab | |
| con | win |
| | |
-------------
The tabbed container on the left has two children. Assume you have focused the
second/right child in the tabbed container. i3 used to focus the first/left
container of the tabbed container when using 'focus right' (it wrapped focus).
With this commit, the default behaviour is to instead focus the window on the
right of the screen.
The intention is to make focus switching more intuitive, especially with tabbed
containers supporting 'focus left'/'focus right' in tree. You should end up
using less 'focus parent' :).
You can force the old behaviour with 'force_focus_wrapping true' in your
config.
Code coverage is 62.5% with this commit.
An example to set all XTerms floating:
for_window [class="XTerm"] mode floating
To make all urxvts use a 1-pixel border:
for_window [class="urxvt"] border 1pixel
A less useful, but rather funny example:
for_window [title="x200: ~/work"] mode floating
The commands are not completely arbitrary. The commands above were tested,
others may need some fixing. Internally, windows are compared against your
criteria (class, title, …) when they are initially managed and whenever one of
the relevant values change. Then, the specified command is run *once* (per
window). It gets prefixed with a criteria to make it match only the specific
window that triggered it. So, if you configure "mode floating", i3 runs
something like '[id="8393923"] mode floating'.
Use 'kill window' to kill a specific window (for example only one specific
popup), use 'kill client' to kill the whole application (or X11 connection to
be specific).
When a tabbed container had more than one child and at least the first one
supported WM_DELETE, i3 entered an endless loop when killing that tabbed
container. This was due to tree_close only sending WM_DELETE without actually
removing the child, while the loop in tree_close assumed that with every call
of tree_close one child would be removed.
Actually, commit 1c5adc6c35 commented out code
without ever fixing it. I think this was responsible for the 'workspace
switching sometimes does not work' bug. My observations:
Had it again today and analyzed a log of it. Looks like after unmapping the
windows on one workspace (in my case: chromium, eclipse, urxvt, focus on
eclipse) we get UnmapNotify events for chromium and eclipse, but then we get an
EnterNotify for the terminal (due to unmapping the other windows and therefore
mapping the terminal under the cursor), only afterwards the UnmapNotify
follows.
So, there are two things wrong with that:
• We handle EnterNotifys for unmapped windows
• Unmapping windows sometimes works in a sequence, sometimes the sequence gets
split. Not sure why (if unmapping can take longer for some windows or if our
syncing is wrong -- but i checked the latter briefly and it looks correct).
Maybe GrabServer helps?
• We don’t ignore EnterNotify events caused by UnmapNotifies. We used to, but
then there was a different problem and we decided to solve the EnterNotify
problem in another way, which actually never happened (commit
1c5adc6c35).
This involves:
• Compiling with xcb-util instead of xcb-{atom,aux} (they merged the libraries)
• Not using xcb-{event,property} anymore (code removed upstream)
• Not using the predefined WINDOW, CARDINEL, … atoms (removed upstream)
• Using the new xcb_icccm_* data types/functions instead of just xcb_*
(for example xcb_icccm_get_wm_hints instead of xcb_get_wm_hints)
Also I refactored the atoms to use x-macros.
Due to lots of cases which were added and added to tree_move(), the function
was not really easy to understand. For this refactoring, I wrote tree_move()
from scratch, thinking about (hopefully) all cases. The testsuite still passes.
The move command also has different parameters now. Instead of the hard to
understand 'before v' stuff, we use 'move [left|right|up|down]'.
Instead, we attach them to their workspace when toggling back to tiling. This
makes more sense; afterall, floating clients are always directly below a
CT_WORKSPACE container.
The file is now created in /tmp using the process PID and the
username of the user running i3. The restart state file is only
loaded when restarting (the --restart option is appended to the
command line prior to the restart). That means that renaming the
old state file with the ".old" extension is no longer needed.
This "--restart" switch is supposed to be only used by i3. The
"-L" switch can be used to load a layout (and not delete it
afterwards). We unlink the state file after we load it so that
we don't keep cruft in /tmp or try to restart from an old config
file if restart_state is set.
Quote from the source:
When the container type is CT_WORKSPACE, the user wants to change the
whole workspace into stacked/tabbed mode. To do this and still allow
intuitive operations (like level-up and then opening a new window), we
need to create a new split container. */
Numbered workspaces (workspaces with a name containing only digits) will be
inserted in the correct order now. Named workspaces are always sorted after
numbered workspaces and in the order of creation.
This fixes the bug which caused floating windows to be visible even when
switching to a different workspace.
Instead of ignoring a specific sequence, we now set an ignore_unmap counter for
each container. (So, should containers be closed too early or stay open even if
they should be closed, we probably need to have a closer look at the counter.
At the moment, it is increased by one on reparenting and unmapping (for
workspace changes) and decremented by one on each UnmapNotify event).
This system is better because a sequence does not describe a single unmap or
reparent request but a request to X11 on the network layer -- which can contain
multiple requests.
The implementation works like this:
Containers can have a 'sticky-group' attribute. Imagine two different
containers (on two different workspaces) which have the same sticky-group.
Now you open a window in the first container. When you switch to the
other workspace, the window will be re-assigned to the other container.
An obvious problem which is not covered with the code at the moment is
having two containers with the same sticky-group visible at the same time.
This helps for windows which are immediately destroyed instead of
unmapped, like when starting i3status | ./foobar | dzen2 -dock
and foobar does not exist (i3status and dzen2 will get a SIGPIPE).
Before this commit, i3 used key bindings in SYNC mode for bindings
like Mode_switch + <a> and replayed the key if the current state
did not include Mode_switch. This had some problems:
1) The WM needed to acknowledge much more key presses than you
actually had bindings for, thus making the system a bit laggy
sometimes.
2) Users of layouts who constantly type in the third level (like
russian layouts) did not get their cyrillic symbols correctly
(they were not replayed right), neither did the keybindings
work in both modes.
So, the current implementation uses the following approach: XKB
provides an event which contains the current state (including
the current level). i3 signs up for this event and upon receival,
it re-maps the bindings using Mode_switch (enables them when the
level goes to the third level and disables them as soon as the
level goes back to normal). This fixes both problems.
This is the foundation to use dzen2 or similar as a complete
replacement for the internal workspaces bar.
A testcase is included, more documentation about the IPC interface
will follow.
Add --force-xinerama when starting i3 to use Xinerama instead of RandR.
This should *ONLY* be done if you have no other choice (nvidia’s
binary driver uses twinview and does not expose the monitor information
through RandR).
This enables compilation with llvm-clang and thus closes ticket #101.
While it makes the code more ugly, I don’t see a beautiful solution
which would enable us to stay with the more elegant solution of
nested functions and still allow compilation with any other compiler
than gcc.
Thanks to Merovius for doing a proof of concept on this one and
being a driving force behind the idea.
Using RandR instead of Xinerama means that we are now able to use
the full potential of the modern way of configuring screens. That
means, i3 now has an idea of the outputs your graphic driver
provides, which allowed us to get rid of the ugly way of detecting
changes in the screen configuration which we used before. Now, your
workspaces should not be confused when changing output modes anymore.
Also, instead of having ugly heuristics to assign your workspaces
to (the screen at position X or the second screen in the list of
screens) you will be able to just specify an output name.
As this change basically touches everything, you should be prepared
for bugs. Please test and report them!
Actually, WM_CLASS contains two null-terminated strings, so we cannot
use asprintf() to get its value but rather use strdup() to get both
of them. Both values are compared when a client is matched against
a wm_class/title combination (for assignments for example).
This makes it more clear that the option is meant to be a special
case (it *disables* part of the focus handling). Also, when
initializing the config data structure with zeros, it will get
initialized with the right value.
Furthermore, the config file parser now also accepts various values
which represent "true", not only numbers.
