* this has been broken since cb5e08b40d

|
* it turns out that option-like arguments could not be reliably passed to
SciTECO scripts for two reasons:
a) "--" arguments are not removed from argv by GOption if it detects
and following option-like argument.
"--" would thus be passed as a script argument which will disable
option parsing in scripts that interpret "--".
b) A script run via the Hash-Bang line "#!...sciteco -m" would
require an explicit "--" to turn of GOption parsing.
However it is __impossible__ to insert after the script file name
on UNIX.
* Therefore, SciTECO now removes leading "--" arguments left over by GOption.
* If possible (Glib >= 2.44), option parsing is performed in strict POSIX
mode which inhibits parsing after the first non-option argument.
This reduces the number of cases where an explicit "--" is required.
* --mung no longer takes an argument. Instead, the first non-option argument
is expected to be the script file name.
This looks weird at first but is more consistent with how other interpeters
work. Once we revise argument passing to scripts, the script name can also
be passed to the script which is more consistent with it being the first
non-option argument.
Also, with strict POSIX parsing, this fixed Hash-Bang lines since
the script file name constructed by the kernel will automatically switch
off option parsing, passing all option-like script arguments uninterpreted
to the script.
* Since we're supporting Glib < 2.44, the Hash-Bang lines are still broken
for certain builds.
Therefore, a wrapper script is installed to libexecdir (it never has to be
executed by users and Hash-Bang lines need absolute paths anyway) which
transparently inserts "--" into the SciTECO command line and should be used
as the interpreter in portable SciTECO scripts.
The wrapper script is generated and points to the exact SciTECO binary
installed. This is important when doing parallel installs of Curses and Gtk
binaries since each one will get its own working wrapper script.
The wrapper-script workaround can be removed once we depend on Glib >= 2.44
(some day...).
* The default /usr/bin/env Hash-Bang lines are no longer used in the
scripts since they are broken anyway (UNIX incl. Linux cannot pass
multiple arguments to the interpreter!).
Scripts that get installed will get a fixed-up Hash-Bang line referring
to the installed SciTECO binary anyway.
* Interface::main() has been renamed to Interface::init() and is optional
now. The Interface::main() method was introduced because of the misconception
that interfaces will find their options in the argv array and have to do
their own parsing.
This is wrong, since their option group already cares about parsing.
Therefore, gtk_init() does not have to called explicitly, too.

* mapped to different registers beginning with "~"
* on supported platforms accessing the clipboard is as easy as
X~ or G~.
Naturally this also allows clipboards to be pasted in
string arguments/insertions (^EQ~).
* Currently, Gtk+, PDCurses and ncurses/XTerm are supported.
For XTerm clipboard support, users must set 0,256ED to enable
it since we cannot check for XTerm window ops programmatically
(at least without libX11).
* When clipboard regs exist, the clipboard can also be deemed functional.
This allows macros to fall back to xclip(1) if necessary.
* EOL handling has been moved into a new file eol.c and eol.h.
EOL translation no longer depends on GIOChannels but can be
memory-backed as well.

* the canonicalized labels are used in title bars and popups
* title labels and popup labels are selectable.
The latter only makes sense as long as there is no mouse support
for selecting popup entries.
* message bar labels are selectable
* title bars can be styled according to the current document type
(.info-qregister and .info-buffer classes)
* .dirty has been introduced for dirty buffers.
This way, dirty buffer file names can be printed in italics
without hardcoding that behaviour. It can be customized in the user CSS.
* The style of highlighted popup entries is now themeable as well
using the .highlight style class.

* this was worked around by using an idle watcher which can
be registered thread-safe.
* this workaround can be reverted once we're single-threaded again.

* This uses the font and size of STYLE_DEFAULT.
* We cannot just pass the font down to the user CSS.
There are no font variables in Gtk CSS.
Therefore we configure the command line widget directly.
This can still be overwritten by an user CSS.
* Instead of using the deprecated gtk_widget_modify_font(),
we generate CSS. Ugly, but still better than writing our
own style provider.
* Font setting is exposed to the user using a new optional
Q-Reg "lexer.font". The numeric part is the point size
multiplied with 100 (fractional point size).
* Font setting in lexer.auto is skipped in Curses
where it is irrelevant anyway to speed up startup.
* Perhaps the "Monospace" font name is also a good default
value instead of Courier?

* this is what the Curses UI does for a long time now
* the popup does NOT cover the info (header) line, as this
would be inconsistent if the header is actually the window's
title bar.
This should perhaps be adapted in the Curses UI as well, so both
UIs look more consistently.
* removed unused InterfaceGtk attribute
|
|
* implemented by exporting the most important Scintilla STYLEs
as CSS variables and defining named widgets for the main UI
components.
* ~/.teco_css will then apply the Scintilla styles to the
Gtk UI.
This file is also for additional tweaks, e.g. enabling
translucency.
* A fallback.css is provided which does just that and is able
to apply the terminal.tes and solarized.tes color schemes.
* Other important aspects of theming like font sizes and names
have not yet been dealt with.
(We may want to apply the corresponding Scintilla settings
to some widgets...)

* many WMs like Unity or even Awesome WM have problems with client-side
decorations.
Awesome WM for instance does not allow us to move or resize
floating windows with CSDs. Also, the added close button does
not make sense for tiling window managers and since they usually
never show window title bars, CSD brings no advantages at all
on tiling window managers.
* Other window managers might not support CSD at all.
* There is AFAIK no way to detect whether CSDs will be possible
or whether there will be glitches (see Awesome).
* Added command line option --no-csd in the --help-gtk group.
This can be added to desktop shortcuts etc. Later there might
be better ways to configure stuff like that, e.g. when we add
support for scripted UI customizations.

* the header bar takes the role of the "info" line in the Curses UI.
* even though the current file was already shown in the window title,
this has certain disadvantages:
* does not work well with decoration-less WMs like awesome.
The file name is important information and should always be at the
top of the window. The space in the task list of awesome is usually
not even large enough to show the file name.
* the title bar uses a canonicalized buffer/Q-Register name.
For the header bar we can use custom renderings using Pango
that highlight control characters just like the Curses UI does.
This is currently not implemented.
* An icon is now shown for the current file.
This is the same icon fetching code that gtk-info-popup uses.
We might want to move that code into a separate module, along
with Pango rendering - Gob2 could just as well generate C++ code.
* For Q-Registers, currently no icon is shown (FIXME).
* Currently, the subtitle is used to indicate which type of document
(buffer or q-register) is edited. This could be done using the
icons only, in which case we can disable the subtitles and save
screen space.
* Client-side decorations are known to cause problems with some
WMs and if using them fails, we end up with a titlebar and header
bar. It is probably a good idea to make titlebar installation
configurable, at least via a command-line switch (or perhaps
ED flag?)

allocation issue
* this is a callback for GtkOverlay's "get-child-position" signal
that allocates a size to the popup.
* cleaner than overwriting the size_allocate method and does not
assume apriori that the popup is part of an overlay.
* the popup was always allocated a few pixels too little height,
resulting the GtkViewbox always scrolling.
Actually it requests a few pixels too little.
We now workaround that by adding a constant value to its
natural height when allocating a position in the overlay.
This is of course a non-portable hack.

* the GTK UI uses the first three resolutions for setting the
window icon.
* the 256px version will currently not be installed.
It may however be used later when packaging for Ubuntu.

|
* use libtool convenience libraries as much as possible
(for all static libraries except Scintilla)
* improves separation of language and user interface implementations
(e.g. the Gtk widgets are not interesting for the rest of SciTECO)
* the Curses popup widget can now be factored out of interface-curses.cpp
* some common CPPFLAGS are now defined by ./configure via AM_CPPFLAGS,
so they don't have to be repeated in each submodule.
* fixed building the Curses UI: GTK_FLOW_BOX_FALLBACK conditional
must always be defined.
