There are some times when we need a Switch Button (aka CheckBox) with more
than 2 states, generally to express check/uncheck/leave-as-is.
This patch extends the Button widget to support the new WBTTriState type,
similar to the existing WBTSwitch except it supports a 3rd state which is
reported to application as '-1'.
The implementation was done in order to not break the binary API. The
version have been incremented in the WINGs header to reflect the change,
but not the version in the 'configure.ac' because that have already been
done in commit c6e323e75d for the next Window Maker release.

Currently WINGs renders text using Xft directly which does not support
any advanced text layout that is needed for scripts like Arabic or Indic
scripts (or even things like automatic ligature support for Latin
script).
With Pango we also get text fallback for free, so no more square boxes
for characters not supported in the current font (unless no font on the
system supports the specified character, of course).
This patch introduces support for using Pango to render the text (though
its Xft backed), to avoid forcing the additional dependency to everyone
it is made off by default.

The information about the File, Line and Function name that were included
in the assertion message are already present from the 'wwarning' macro, so
it is not necessary to include them in the macro's message.

In many places of the code these functions are counting on the "return"
effect of these macros to gracefully handle incorrect arguments. So, when
debug is not enabled, if it is okay to not display a message it is however
not good to completely skip the check and skip the early return.
This patch changes the macro to always perform the check and return to
avoid crashes, displaying a message only when NDEBUG is not set.

In commit b4cb488, wprogressindicator.c was removed. It was restored in commit
d435ea7, but the corresponding declarations in WINGs/WINGs.h were not. This
patch fixes this oversight.
This patch is used to add support for syslog messaging implemented in
WINGs lib directly, so available from the lib itself and wmaker too.
I believe it will in a first time help to get some logging info
centralized in one point, and in a second time maybe add some info
level messages like wmaker is starting, stopping, restarting and else.
For now, it's built by default when the syslog support is found, maybe
we could also disable it by default.
Although this is a modification of the public API, this patch does not
change the binary interface, and the attribute does not add a constraint
on the parameter for the caller so we do not break the source compatibility
either.

As suggested by GCC, this function is a good candidate. There is a little
constraint on how to do it however, as it is part of the public API so we
have to do it in a portable fashion (We can't rely on our "config.h" when
the file will have been installed).

The new macro 'wlengthof' returns the number of elements for which a local
array have been defined, which makes code easier to read than the
previous [sizeof() / sizeof([0]) ] construct.
The macro includes a static assertion to stop compilation if it is being
used on a pointer, for which we cannot know the size of the array, to
avoid generating dummy result. This can work only with C11 which
standardised the static assertions.

As reported by Iain Patterson, the clang compiler is (by default)
strictier on having clean C syntax. A few structure definition
did not comply, now they do.

The declarations have been split by source file, adding the usual
separation mark. Removed these 2 prototypes:
- W_SetFocusOfToplevel: case typo, the correct prototype already existed
in the file;
- W_TextWidth: function is not defined anywhere
To be able to do this in a clean way, it was necessary to add the
attribute also in PLData's ptr field, which is actually right
because none of the function changes its content.
The function that fills it from a file/pipe however needed small
changes to respect the const-ness of the field.
According to the way its value is being used everywhere, that is
what would be expected, so let's make it official.
Please note that this may introduce warnings on user code using
this function ("...discard const...") but that's an opportunity
for them to check that their code is not doing anything wrong.
This makes the WUtil API as much const-correct as possible for
the arguments being given to its functions.
This does not make it totally correct as it does not changes the
const-ness on returned values because the goal of this patch is
to make no visible change to existing program that would use this
library.
Note that the argument is also stored as-is in the PLData structure
but only for debugging purpose (warning display to user), hence the
choice to not duplicate it. As a side effect, it was 'const'-ified
too to reflect that.
As a side note, in 'wfindfileinlist' the first argument should be:
const char * const *path_list
However, due to limited support for const in plain C, that would
introduce warnings in user code. For compatibility issues, this
was not implemented.
A number of functions do not actually modify the strings given as
parameter, but only read or duplicate it. In this case it is a good
practice to mark that parameter as pointer-to-const to let the
compiler known about it, to be able to perform appropriate
optimisations.
This functions reads a proplist from a pipe instead of a file (like
WMReadPropListFromFile does). It uses a call to popen to open the desired
command, reads data into a buffer till EOF and passes the data to getPropList
for parsing.
v2: code cleanup
The new function W_setconf_doubleClickDelay() sets the value for
WPreferences.W_setconf_doubleClickDelay(), therefore the private
data of WPreferences struct is not used.
This call is used at defaults.c to set the doubleClickDelay().
These new functions:
unsigned W_getconf_mouseWheelUp(void);
unsigned W_getconf_mouseWheelDown(void);
returns the WINGs configuration for the Mouse Wheel Up and Down
values.
A number of macros are pre-defined by WindowMaker for CPP in the
function 'MakeCPPArgs', they are now available in the internal
parser too. CPP also had some predefined macros, a subset of them
have been added.
The definition have been split in two parts:
- the macro that are dependant on WindowMaker parameters are
defined by WindowMaker (src/rootmenu.c)
- those that are independant, which can be defined by the parser
itself (WINGs/menuparser_macros.c)
The parser is prepared to handle '#' directives, starting with file
inclusion. The search path for the file are taken from what was
actually given to CPP. There is an arbitrary limit to the inclusion
nesting, which is actually not a design limitation but a security
to avoid infinite include loops.
The default function used so far provides informations not so useful
to user, like wmaker's source file, line number and function; it
also cannot provide the line number from the parsed file because cpp
messes this information.
With this dedicated function we try to provide useful things which
are being tracked by the parser internally, like valid line number
and the name of the file being read (which can be convenient in the
case of #include, for which we may also be able to provide the
inclusion tree!)
From caller point of view, the two function have been merged into a
single function in the API. This will be needed by the advanced
parser that will have to not separate the concept of a 'line' and
the concept of 'content' (due to empty/comment lines, multi-line
comments, long lines split with '\')
All the information related to the file being parsed are stored in
a single place. The content of this structure is not visible to
caller to avoid messing the content; the parsing will be handled as
methods to this object.
Please note that all functions visible as part of the parser's API
are using the CamelCaseNotation to be consistent with the rest of
the API; however all internal functions use the non_camel_case_syntax
to follow the coding style set by Carlos for the project.
Due to the tasks to take in charge, the internal parser will grow in
size to support basic CPP feature, so it is a good idea to start by
moving the current functions into a dedicated file.
The declaration of the structure actually also created an unused variable. This
variable was not used anywhere, and lead to symbol defined in multiple objects.
These symbol are silently merged by GCC, thus no problem was reported.
The issue was raised by Yves de Champlain when trying to compile with LLVM/clang
which is a bit stricter there.
...in order to avoid clashes that happen during compilation of
wmakerconf.
This is a new function in WINGs, so renaming it at this point is
not a big deal.
Thanks to Rodolfo García for the heads up.
This is essentially the fetchFile() from wcolorpanel.c from the last
commit, but renamed to a better name.
This patch just adds the function to the lib. Nobody uses it yet.
This reverts commit f4890b17e6.
It turns out that I needed some functions from wtext.c to develop
a WINGs front-end to my comic book collection MySQL database.

* Remove assigned but not used variables (GCC 4.6)
* Bump _XOPEN_SOURCE to 600, ridding of FreeBSD warnings (this probably need
to be tweaked on a per-implementation basis as problems arise)
