The %{PR} tag is introduced for this. It resets all colors as well as
the activation of the underline and overline and font.
This has become necessary because we don't track what raw tags a user
injects into the formatting string and otherwise their raw tags could
bleed through.
This doesn't touch action tags because even before raw action tags
weren't being tracked. Action tags also have the requirement that they
have to be used in pairs, so closing them prematurely could break things
(for example with click actions for the entire bar)
Using a bit vector to track the active attributes does not really give a
significant speed increase, especially for only two attributes
Checking if a syntaxtag or an attribute exists in the map just adds
unnecessary code
Was around since the first commit but no documentation why. It was only
used in the text module and doesn't appear in any public documentation,
so this doesn't break anything.
This is the next step to merge #1237 in stages.
Currently there are barely any restrictions on how the config can be
written. This causes things like config files with DOS line endings to
not be parsed properly (#1366) because polybar splits by `\n` and when
parsing section headers, it can't deal with the `\r` at the end of the
line and thus doesn't recognize any section headers.
With this PR we introduce some rules as to what characters are allowed
in section names and keys.
Note: When talking about spaces I refer to any character for which
`isspace()` returns `true`.
The rules are as follows:
* A section name or a key name cannot contain any spaces as well as any
of there characters:`"'=;#[](){}:.$\%`
* Spaces at the beginning and end of lines are always ignored when
parsing
* Comment lines start with `;` or `#` and last for the whole line. The
whole line will be ignored by the parser. You cannot start a comment at
the end of a line.
* Section headers have the following form `[HEADER_NAME]`
* Key-value lines look like this:
`KEY_NAME{SPACES}={SPACES}VALUE_STRING` where `{SPACES}` represents any
number of spaces. `VALUE_STRING` can contain any characters. If it is
*surrounded* with double quotes (`"`), those quotes will be removed,
this can be used to add spaces to the beginning or end of the value
* Empty lines are lines with only spaces in them
* If the line has any other form, it is a syntax error
This will introduce the following breaking changes because of how
underdefined the config syntax was before:
* `key = ""` will get treated as an empty string instead of the literal
* string `""`
* Any section or key name with forbidden characters will now be syntax
errors.
* Certain strings will be forbidden as section names: `self`, `root`,
* `BAR`. Because they have a special meaning inside references and so a
* section `[root]` can never be referenced.
This replaces the current parser implementation with a new more robust
one that will later be expanded to also check for dependency cycles and
allow for values that contain references mixed with other strings.
This PR also now expands the config paths given over the command line so
that `--config=~/.config/polybar/config` resolves properly.
Closes#1032Closes#1694
* config_parser: Add skeleton with tests
First step in the config_parser develoment. Only tests functions that
are easily testable without many outside dependencies. Integration tests
will follow.
* config_parser: Implement parse_header
* config_parser: Implement get_line_type
* feat(string): Add trim functions with predicate
Not only trimming based on single character matching but based on a
freely specifiable predicate. Will be used to trim all spaces (based on
isspace)
* config_parser: Implement parse_key
* config_parser: Implement parse_line for valid lines
* config_parser: Throw exception on invalid lines
* config_parser: Remove line_no and file_index from parse_line
Cleaner to let the caller catch and fill in the line number and file
path
* string: Clear up misleading description of trim
Before, trim would remove all characters that *didn't* match the
predicate and thus the predicate isspace wouldn't work correctly. But
because we used the inverse (isnospace_pred) it all worked out, but if
the function was used with any other function, it wouldn't have given
the desired output
* config_parser: Implement parse_file
* config_parser: Switch operation to config_parser
This changes the way the config is invoked. Now main.cpp creates a
config_parser object which then returns the singleton config object from
the parse method. Subsequent calls to config::make will return the
already created config object as before
The config_parser does not yet have all the functionality of the old
parser: `inherit` directives are not yet resolved. Other than that all
the old functionality is implemented (creating sectionmap and applying
include-file)
Any sort of dependency detection (except for include-file) are still
missing
* config: Move xrm initialization to constructor
config_parser handles the detection of xrdb references and passes that
info to the config object.
This finally allows us to delete the config::parse_file function because
everything in it has been implemented (except for xrdb detection and
file error handling)
* refactor(config_parser): Cleanup
* config_parser: Set config data after initialization
Looks much cleaner this way
* config_parser: Expand include-file paths
* config_parser: Init xrm if the config uses %{xrdb references
* config_parser: Use same type of maps as in old impl
Polybar has some weird, not yet fixed, inheriting behaviour and it
changes depending on the order in which the config stores its data.
Using the same type of maps ensures that the behaviour stays the same.
* refactor(config_parser): Clearer invalid name error message
* config_parser: Don't allow reserved section names
Sections with the names 'self', 'BAR', 'root' could never be referenced
because those strings have a special meaning inside references
* config_parser: Handle inherit directives
This uses the old copy_inherited function, so this still suffers from
crashes if there are cyclic dependencies.
This also fixes the behaviour where any key that starts with 'inherit'
would be treated as an inherit directive
* config_parser: Clearer dependency cycle error message
* refactor(config_parser): Handle file errors when parsing
This removes the need to check if the file exists separately
* fix(config): expand config file path
Now paths using ~ and environment variables can be used as the config
path
* fix(config): Properly recognize xrdb references
* config_parser: Make messages more informative
* doc(config): Improve commenting
Comments now describe what the config_parser actually does instead of
what it will do.
We also now follow the rule that single line comments inside functions
should use `//` comments
* refactor: Move else on same line as curly braces
* fix(config_parser): Don't duplicate paths in `files`
* refactor(config_parser): Use else if for clarity
* fix(config): Undefined behavior in syntax_error
Before the custom what() method produced undefined behavior because the
returned string became invalid once the function returned.
* refactor(config): descriptive name for useless lines
is_valid could easily be confused as meaning syntactically invalid
without it being clarified in a comment
* refactor(config): Use separate strings instead of key_value
Takes just as much space and is much better to read
* fix(config_parser): TestCase -> TestSuite and fix macro call
Ref: #1644
* config_parser: use const string& in method args
* config_parser: Improve comments
* config_parser: Incorporate review comments
Originally the size function returned the scaled `size` property for
scalable fonts and the non-scaled `pixelsize` property for non-scalable
fonts. This caused lots of issues when that property was 0 (empty bars,
characters not drawn without warning, see references at the bottom).
This behavior was mostly observed on debian where `size` is set to 0 if
`pixelsize` is set.
We now try to use both properties for both types, but prefering `size`
for scalable fonts and `pixelsize` for non-scalable ones.
This behavior doesn't break existing correct behavior but now never
returns 0. It will always try to fall back to the other property or to
some fallback value if both properties are 0.
I originally thought this could also make font patterns more expressive
by being able to specify the size of scalable fonts directly in pixels
like so:
Unifont:size=0:pixelsize=20
or to scale non-scalable fonts by forcing polybar to fall back to the
`size` property (which is always scaled):
Wuncon Siji:pixelsize=0:size=20
But how these two patterns are matched by `fc-match` depends both on the
font and on the distro/fontconfig setup.

I don't know the original intention behind this but it clutters up debug
traces and basically makes ccache useless.
The only benefit it has, giving version info in stacktraces, is kind of
void since we already ask for version information on github issues.
Displays real percentage instead of being set to 100 if percentage > full-at
* battery: added percentage_raw token, which ignores full-at
* battery: current_percentage returns raw, added clamping function instead
* battery: clamp percentage used by build()
Made clamp_percentage() const to allow its usage inside build()
* battery: read and return percentage in one line

We need to have the version string available in multiple places not just
the source code. It is now hardcoded in the root CMakeLists.txt and all
files that need it will be configured with cmake.
This also removed the unecessary duality of GIT_TAG and APP_VERSION and
GIT_TAG_NAMESPACE and APP_VERSION_NAMESPACE.
tray_client class contains a reference so copy assignment operator is implicitly deleted.
the dtor unembed the window so copying the class could lead to bug so the copy ctor is also deleted.

If any signal receiver throws an exception for any reason after
receiving a signal, no one would find out about it because the signal
emitter just ignored exceptions
Also actually delivering the signal caused some exceptions because not
all signals have a receiver.

Polybar had issues when there is no background set or set by a tool like imagemagick which doesn't add the root pixmap to the root window properties.
There's not much we can do about it, but at least polybar doesn't crash anymore.

This adds `monitor-exact = true` in the bar section
This also properly does best-match instead of first-match if multiple
matches exists. For example if there are two monitors HDMI2 and HDMI-2
and we try to match HDMI-2 with monitor-exact = false, until now HDMI2
would be matched. Now exact matches are always preferred.

This adds a new label in the bspwm module `label-marked`

Resolves#1552
[1]: d0138af475
This patch adds support for observing multiple slices of the desktop background.
This is used for the tray so that it doesn't have to rely on the bar's rect to
get the desktop background. In particular, it now handles the case where the
tray is not contained fully within the bar's outer rect (for example, when using tray-offset-{x,y})

The previous approach relied on manually updating the version and date
using a Makefile
This approach dynamically gathers the correct version from git and uses
the date of the latest commit in the branch
* Clean up CMake logic
- removed logic to find CppUnit (no longer used)
- removed "dirs" variable used to pass include directories
- removed add_library function (no longer used)
- removed make_executable function
* only used in 2 places (polybar and polybar-msg)
* it was more general than needed, logic is simpler without it
- split polybar into static library and executable
* this allows linking unit tests to the library
* rename library
* add coverage build
- Added a CMake build type "Coverage" that builds C and C++
code with the "--coverage" flag (recognized by both GCC and Clang)
- removed "-Wno-missing-field-initializers" from test flags,
since it didn't seem to be needed any more
- removed logic from tests/CMakeLists to disable "-Werror" and "-pedantic-errors"
since there didn't seem to be any warnings during the build
* fix whitespace
* update travis
* remove O2 from defalt flags
* allow tests to be built by default make target
* disable Werror for debug builds
If FcNameParse returns NULL FcDefaultSubstitute segfaults
We log and throw an error here because the signal emitter swallows all
exceptions so if that exception was thrown, the bar would stop rendering
without any indication as to why.
Fixes#1435
wireless_tools 29 redefines inline in iwlib.h as:
#define inline inline __attribute__((always_inline))
which conflicts with POLYBAR_NS, which is defined as:
#define POLYBAR_NS \
namespace polybar { \
inline namespace APP_VERSION_NAMESPACE {
In version 30.pre9 this #define is moved into a source file and thus
cannot conflict.
The error only occurs when building with clang, so it seems gcc and
clang handle this differently
Fixes#1492
We need to use positions relative to the position of the bar for indexing into
the background image slice, but the code used absolute ones.
This worked fine as long as absolute positions are the same as relative
positions (this is the case for a bar located at (0,0), so if bottom = false).
But for bottom bars (where the bar position is not (0,0)) this was wrong which
caused the tray background to be black (out of bounds for the background slice).
The systray only supports pseudo transparency (real transparency would require
much larger changes) so the real transparency should only be used for the bar itself.
We now take the bar position that the window manager gives us instead of trying
to calculate it ourselves. This is more correct when multiple bars are attached
to the same edge, as the window manager may move some of them in that
case (assuming override redirect is not enabled)
We need to fetch the outer area from the root window, not just the inner area
because we paint the background below the borders as well.
This has the nice effect of supporting semi-transparency for borders as well.
Now all the tokens in the memory module also have ramp and bar counterparts.
These can be used exactly the same as `bar-used` and `ramp-used`, they are named `<bar-swap-used>`, `<bar-swap-free>`, `<ramp-swap-used>`, and `<ramp-swap-free>`

* `0 < label-NAME-maxlen < 3` will now throw an exception and disable the containing module, if ellipsis is enabled for that label. (#1198)

The check of the maxlen and ellipsis condition was also moved to the
label creation, this way get_label_text doesn't need to care about the
restrictions placed on maxlen and ellipsis
The repeatone button doesn't influence repeating behaviour at all, so
the name is misleading.
This deprecates icon-repeatone for now, until we can completely remove
it
Fixes#1279
This patch enables support for nl80211. In case the libnl-genl-3.0
library isn't found, it will fall back to Wext instead.
The library to use can also be manually set with the CMake option
WITH_LIBNL.
The Wireless-Extensions (WE or Wext) are deprecated and long replaced
by cfg80211.
Although Wext isn't used by WiFi drivers anymore, CFG80211_WEXT allows
old tools to communicate with modern drivers by providing a wrapper
API.
It's queried the same way ipv4 addresses are queried, but here it displays globally routable addresses. If there are multiple such addresses, it picks one (same as with ipv4). It's possible that an address discovered this way is not in fact globally reachable but still marked as global.
Using brace initialization here causes bar.hpp to not compile when
included on its own, forcing all clients to also include
tray_manager.hpp and so on, which defeats the purpose of forward
declaring those classes.
This also allows us to remove the tray_manager.hpp, renderer.hpp and
parser.hpp includes from the clients of bar.hpp
Only updating when an mpd event occurred would cause issues when mpd was
playing and the machine was put to sleep because the elapsed time was
calculated by taking the time difference of the last update and now
which would give you wrong numbers, if the machine was in standby in
between.
Since the update function on the module is only called once a second (or
when an event happens), we can just update the data every time without a
huge performance hit.

expand-right defaults to true to preserve the current functionality
If set to false, the items in the menu will be added to the left of the
toggle label (instead of the right side)
Should resolve the issue discussed in #655
If the mouse was at the leftmost edge of the screen and there was an
action area from 0 to N, the click wouldn't register
Before if an action area was defined from A to B it was from A exclusive
to B inclusive now it is from A inclusive to B exclusive. This is the
same way that the pixel addresses work, since a pixel's coordinate is
defined by the top-left corner.
Fixes#661
When focusing a desktop with the urgent flag, two events are received
from `bspc` simultaneously, separated by a newline character.
This was not handled correctly and the second event was discarded causing
the urgent style to be removed, but the focused style would remain on the
previously focused desktop.
This fixes the problem by handling any number of events that arrive at the
same time (separated by newlines).
