None of the payload fields seem to be used. They were the only place
where EVENT_SIZE was used and why it had to be a macro (no variable
length arrays).
Since APP_VERSION is different for every commit and almost all file
include settings.hpp, the whole project has to be rebuilt for every
commit. With this, hopefully, this can be greatly reduced and only
changed files need to be rebuilt. This will also help ccache
Some people use text modules instead of the `separator` key in the bar
section to better configure the separator (colors, fonts).
Since we disallowed the same module being used multiple times in #1534,
this will now print an error message.
This should help with this a bit.

Since all of polybar is built at once, there is no chance that this is
ever linked to an object that was compiled with another `-std=`

Some WMs like i3 discard position information when unmapping the bar and
because of that the bar would be at the wrong position after being
remapped.

* refactor: Use flat module list if possible
Before if you wanted to iterate over all loaded modules you had to first
iterate over all blocks and then over their modules even if you didn't
care about alignment.
* refactor: setup modules in separate function
* controller: Print error for duplicate modules
You can't use the same name twice inside the module lists
E.g.
modules-left = a b c
modules-center = a
modules-right = b
would print an error.
We only print an error for now because we don't want to break existing
configs. But in the future this should be properly enforced.
A workspace is occupied if it is not active and there is at least one window managed by the WM (`_NET_CLIENT_LIST`) that has set `_NET_WM_DESKTOP` to that workspace.
The behavior when `_NET_WM_DESKTOP` is not set is not yet clear but this is unlikely to happen since most WMs will position windows on some desktop.
Closes#874Fixes#1444Fixes#1033
* Set Desktop OCCUPIED if a window moves there
This covers more of an edge-case. I did this first by accident, it might
vanish later on.
* Replace tracking change of WS with currently used WS
* Untrack occupied workspaces
* Track windows and their desktops in pairs
* Match type of occupied_desktops with current_desktop
Because the index needs to be matched later on, type mismatches would be non-ideal.
* Recreate the occupied desktops everytime and remove duplicates
* Readd support for moving windows to other desktops
* Use less characters to empty the vector
* Rename variable storing the desktops
* Recount windows on every occasion
This alone simplifies the management and the lookup for occupation of a
workspace
* Keep track of number of windows in every workspace
* Add debugging output that shall be removed before merging
* Remove obsolete TODO
* m_client_list should always be diff'd, since the desktop may change
Therefore we update the desktop-count tally every time the client_list
changes. It may just be a desktop-change without a change of
clients.size()...
* Add more logging-spam to understand window/desktop lifecycle
* Lock event-handler to serialize handling of events
* Fix occupied workspace counting and change to bool array
Also, performance improvements when diffing new and old client lists
* Fix crash when all clients are removed
* Conform to linter and styleguide
* Shorten conditional as it is standard enough
Since this only guards against 0-divisions, it can be shortened
without risking too much confusion down the road.
* Guard against multiple threads accessing and modifying data
Fixes#1444
Modification of internal data happens through the handle-method, while
the build-method tries to access the data structures for display. Since
some modifications clear e.g. the m_viewports, references may become
invalid between looping over them an accessing them.
The mutex should guard against this simultanuous access.
* Do not 'adopt_lock', because calls come from very different threads
To my understanding, adopt_lock has some dependency on the mutex-ownership. Since
the lock is once called from the inside (in handle) and once from the outside (in
build), there might be a problem. After brief testing, the segfaults happened fewer
times.
See #1444
* Also listen to _NET_WM_DESKTOP
In order to move a window from one desktop to another, it is sufficient
to set the desktop-property of that window. xmonad fires a lot of events
in the case of moving a window, herbstluftwm only updates the
_NET_WM_DESKTOP-atom of the window.
This change reloads the clientlist in order to correctly set the
desktop state "occupied".
* Describe need and use of mutex
It might be possible to relieve the guard in xworkspaces_module::handle,
but I am unsure about this. Since xmonad emits a lot of events on almost
every minor change, I would let the guard keep its post, avoiding
race-conditions in event-handling.

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.

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.
