Having the new object layout will be important soon when the
append/remove methods start to get added to the client and the
reborn `awful.keyboard` module.
The `:keys()` and `:buttons()` APIs moved from get/set single methods
to properties. It works fine if you use the new or old API, but has
limitations when mixing them. `awful.rules` calls properties in a loop
after checking if it is a function. Thus it triggers the secondary
codepath to try to handle this case.
This codepath was tested with gears.objects based components
(ie. widgets). It was not tested with clients and tags, and it
didn't work because they use `awful.tag.getproperty` and
`awful.client.property.get` instead of `._private` like all
newer components. Those old functions are officially deprecated,
but used by tons of configs and modules ported from v3.5 and thus
still the default way to access Lua properties in our implementation.
This commit adds a `_private` to anything that doesn't have one to
at least make the error stop. It will "mostly" work until a more
complete solution is added. Reverting the 2 PRs that changed this
would delay getting more feedbacks.
Many legacy Awesome APIs such as `client:tags()`, `root.buttons()`,
`client:keys()`, `drawin:geometry()`, etc used functions for both the getter
and setter. This contrast with just about everything else that came after
it and is an artifact of an earlier time before we had "good" Lua object
support.
Because both consistency and backward compatibility are important, this
table wrapper allows to support both the legacy method based accessors
and key/value based accessors.
It isn't part of the public API, has a sledgehammer function prototype
and is intended for internal use only.
It's ugly, but backward compatibility is more important than anything
else.
This function allows to update the content of a table using the
content of a second table. It helps to keep the original reference
and to know what has been added and removed.
Nobody wants to set this parameter. It is necessary because the old
API allowed `awful.rules` to be used with random for random matching.
This stopped "really" working between the 3.4 and 3.5 release because
the code started to accumulate "corner case" fixes aligned with the
client properties. v4.0 added more ordering and v4.3 added external
sources. After this, it is unusable with external objects, but
`gears.matcher` handle this use case very well.
In a perfect world we would have pure expression matching, but
that's problematic with all the "metaness" of the code. For now,
this adds an imperfect way to match the minimum and maximum of
number properties.
It will be used by the screen rules for the DPI and size properties.
This is hardcoded in `awful.rules`, but cannot be shared due to the
priority corner cases. Given in the long run any "standard" priority
should use the topological sort API, better not try to share *that*
code.
It is now possible to add and remove rules. This is superior to how
`awful.rules` originally handled rules because modules can now
assume adding and removing rules works.
The reason for the methods rather than `table.insert` is partially
because future commits will add signals. In turn, this will allow
`gears.matcher` to be extended by module using it using the extra
"introspection" made possible by the signals.
A call to cairo_close_path() adds a straight line to the beginning of
the current sub-path. This is used in some of the shapes to, well, close
the shapes.
Sub-paths can be created explicitly via cairo_new_sub_path(), but also
implicitly via cairo_move_to(). When a new sub-path is started, there is
no current point on the path. This means that e.g. cairo_line_to() is in
this start equivalent to cairo_move_to() (= no line is created) and that
cairo_curve_to() first does a cairo_move_to() to the beginning of the
curve. Similarly, cairo_arc() and cairo_arc_negative() first do a
line_to() to the beginning of the arc, and this line_to() can be
implicitly turned into a curve_to().
The problem with the code in gears.shape is that parts of the code
(implicitly) assume that there is not yet any path when the shape
function is called. If this assumption is broken, the call to
close_path() could go to the wrong point, because the path did not start
at the expected position.
Most of the functions in gears.shape already implicitly start a new
sub-path via a call to cairo_move_to(). Those that do not (necessarily)
begin with a call to cairo_move_to() are handled in this commit: They
get an explicit call to cairo_new_sub_path().
This change fixes the issue reported at
https://github.com/awesomeWM/awesome/pull/2804, because the shapes will
no longer be influenced by the pre-existing path. The move_to() that was
left around and caused that issue turns into a degenerate part (it only
has a move_to(), so nothing can be drawn) and is then discarded by
cairo.

This way their name doesn't get mangle by the broken magic. It will also
eventually allow to `error()` in the template when the implicit
`@function` is used.
This commit also fixes a large number of issues found while
proof-reading everything.
ldoc has a magical `@classmod` module type which tries to detect
what is a method and what is a static function. It fails about as
often as it works. This commit makes everything explicit to remove
such issues.
Fixes#2640
Ref #1373
GLib has an internal pseudo-RNG that it initialises from /dev/urandom.
This commit adds code that uses this RNG to initialise various random
number generators that can be used by Lua.
This also removes some Lua code that initialises the random number
generator badly.
