mihaicmn ad7dec31d5 Use the DPI setting within the i3bar () 2016-11-12 06:34:54 -08:00
Michael Stapelberg f354f53435 Ensure all *.[ch] files include config.h
Including config.h is necessary to get e.g. the _GNU_SOURCE define and
any other definitions that autoconf declares. Hence, config.h needs to
be included as the first header in each file.

This is done either via:
1. Including "common.h" (i3bar)
2. Including "libi3.h"
3. Including "all.h" (i3)
4. Including <config.h> directly

Also remove now-unused I3__FILE__, add copyright/license statement
where missing and switch include/all.h to #pragma once.

Michael Stapelberg 0e73a6e9e7 Remove conditional compilation for cairo/pangocairo ()
We strive to avoid conditional compilation in i3 as much as possible.
cairo and pangocairo have been around long enough in the versions that
we need that it’s time to unconditionally depend on them.

Also update DEPENDS with the last-known-good-versions while at it.

Alex Auvolat c6a4e4519f Correct color management for pango fonts
Corrects the cases where the colorpixel is not 0xRRGGBB : we have to
use the full color_t struct to describe font colors, as Pango expects
RGB values and not an XCB colorpixel value.

Ingo Bürk a5d4c7c9ab Allow text drawing to use the alpha channel.
We pass alpha channel information to the current text drawing code
and use it if it is available. The previous behavior of using full
opacity for RGB format colors is preserved.

Ingo Bürk 1c4100ce5d Use 32-bit visuals for i3bar when possible and allow RGBA colors.
This patch creates all necessary windows for i3bar with 32-bit visuals if available.
It also introduces the possibility to define RGBA colors (next to RGB colors), which
allows the user to set the opacity of any color. This requires running a compositor.

With this patch we also start supporting _NET_SYSTEM_TRAY_VISUAL, which is necessary
for the tray icons so they create the tray window with the correct depth and visual.

Ingo Bürk 5a8d66a1d5 Parse the title_format and display the customized window title if a format was set.
The format string set with "title_format" can contain the placeholder "%title" which will be replaced with the actual window title.

By not overwriting window->name itself, we make sure that assignment matching still works as expected.

shdown 123de9a25f Fix incorrect y-offset for text in i3bar (2)
014aa7ff74 fixed incorrect align of small
symbols, but also introduced a problem with texts with mixed large and
normal symbols. Fix it by centering the text vertically only if its
height is smaller that the saved font height.

incorrectly calculated in case all characters in the string to draw are
smaller than the cached font height. Fixes .

Tony Crisci e18e2b9f98 i3bar: use Pango markup
Parse text within workspace buttons and the i3bar statusline as Pango
markup. This lets people specify things like font weight, text color,
background color, font size, and font family in the text of i3bar.

Tony Crisci e91a9174e2 libi3: free previous font on font load
When loading a new font with `load_font`, free the previously loaded
font with `free_font`.

If no font is loaded, `free_font` will simply return (instead of
crashing because of a double free).

aszlig 9058fc44e6 Allow to validate the config file without X.
We're going to call parse_configuration() very early if -C is given on
the command line. Instead of the previous "only_check_config", which has
been a global variable, we now simply pass use_nagbar as false if we're
just validating.

This causes the whole parsing to run without X and of course without
starting nagbar and displaying the errors to standard out/error instead.

The return code of parse_configuration() is now a boolean which
represents whether an error occured during parsing and the programs exit
code is returned accordingly.

Although the config parser still has a lot of side-effects, we now can
parse without the need to have an XCB connection. A nicer implementation
would be to just set the new font and load it just after we're done
parsing, but to ensure we don't break functionality we just load a dummy
FONT_TYPE_NONE if XCB isn't available. The main reason for going this
route is that it's a bit difficult to test fonts in a distribution
agnostic way without bundling fonts with i3 (or Xdummy to be more
exact).

Michael Stapelberg 9200094203 format **/*.c with clang-format-3.5
This has multiple effects:

1) The i3 codebase is now consistently formatted. clang-format uncovered
   plenty of places where inconsistent code made it into our code base.

2) When writing code, you don’t need to think or worry about our coding
   style. Write it in yours, then run clang-format-3.5

3) When submitting patches, we don’t need to argue about coding style.

The basic idea is that we don’t want to care about _how_ we write the
code, but _what_ it does :). The coding style that we use is defined in
the .clang-format config file and is based on the google style, but
adapted in such a way that the number of modifications to the i3 code
base is minimal.

Michael Stapelberg 0883dfbe14 only LOG() the DPI when it changes, DLOG() it otherwise (Thanks lkraav)
This avoids flooding stdout every time some text (e.g. a window
decoration) is drawn, yet leaves the message in place when it’s actually
relevant (upon DPI changes).

Bas Pape 1d6450f0e8 libi3/font: Set DPI for the pango context
The pango font specification accepts a font size in points, but pango
defaults to a DPI of 96. Create a default PangoContext (which
internally creates a default PangoCairoFontMap as usual) and set the
DPI to the value of the root Screen manually.

Michael Stapelberg 2896ae8057 logging: make libi3 use verboselog()/errorlog(), provide it in each caller
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

Michael Stapelberg 206b96202c Use (void) instead of () for functions without args (Thanks fernandotcl)
See also:
http://article.gmane.org/gmane.linux.kernel/1268792

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.

Fernando Tarlá Cardoso Lemos 340592a532 Invalidate cached pixmaps on reload and redraw.
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.
