Action strings now have the form '#MODULE#ACTION'
For example to trigger the action 'toggle' in the 'module/date' module
one would now use '%{A1:#date#toggle:}'
With this action strings can now be uniquely assigned to one module.
Fixes#1172
If an input is enqueued as a response to an input, the new input will be
swallowed because it will likely be enqueued less than 30ms after the
original event.
This is not something that is an issue right now but it is required to
finish #1907 where, in order to close the menu after a click, the menu
module gets an exec action that closes the menu and adds a command to
the event queue.
The setting also isn't too useful since it will just break polybar input
handling if inputs arrive too fast instead of (possibly) slowing down
the bar.
It is useful for people to see what config file polybar loaded.
For debugging font issues people almost always need to check what fonts
polybar loaded, for that they need to run polybar with info logging. Now
this information is always provided. This requires an update in the font
wiki page.
A warning implies something went wrong and (possibly) the user should do
something about it. However, warnings are not always used this way.
For example:
* When a fallback value for a `${..}` reference is used, this shouldn't
produce a warning (or notice) since using fallbacks is not something
bad.
* pulse telling you that it uses the default sink because no sink was
specified also does not warrant a warning (even notice may be too
high).
* Whenever polybar shuts down it produces a "Termination signal
received..." warning. Since there isn't a more proper way to shut down
polybar, it should not produce a warning. Same argument for a
`screenchange-reload`
Before it would only reload if the size changed and even that was
reliable since the method relied on the order of the monitor list.
Now if the monitor list differs in any way (pos, dimension, primary,
output, name) a reload is issued
Removing monitors is not really necessary when selecting the monitor
where to render the bar or choosing the backlight. Since both monitors
occupy the same coordinates rendering can be done on both and it's
better to give people felxibility for the backlight.
Fixes#1191
Premature optimization that tried to cache monitors but the cache did
not take into account the parameter values.
The call `get_monitors(..., ..., false, true);` would get all connected
and unconncected monitors a subsequent call
`get_monitors(..., ..., true, false);` would get back the same list of
monitors even though it requested only connected monitors.
Additionally `get_monitors` is never called periodically so the
optimization really didn't help much.
Functionality-wise reverts the changes from #1534
In #1907 we have decided to allow the same module to appear multiple
times (and deliver actions to all matching modules). But since that PR
will likely take longer to get merged, I want to remove the error from
polybar because the message it prints isn't really true anymore.
The old code didn't really work when the right block was pushing against
the center block. Also `fixed-center` wasn't properly defined. I have
now fixed it to the following:
* `fixed-center = true`: The center block stays at the center of the bar
whenever possible. It can be pushed to the left if the right block takes
too much space and to the right if the left block takes too much space
* `fixed-center = false`: The center block will be in the middle between
the left and right block whenever possible. If there is not enough space
between those two, the center block will be directly to the right of the
left block and pushes out the right block
The issue was that it used the position of the center module to
calculate the leftmost possible position of the block. However, if the
center module is empty that position is disastrously wrong.
Fixes#591Fixes#1903
the `node` and `node_repeat` were never called with the optional
parameter add_space. And its default value is false, so the
corresponding code was never used.
I think in general it is better to just have the user of those functions
call `builder::space` when they need to instead of adding more
complexity to the `node*` functions.

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).
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.
Ref #1913
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.
Fixes#1484
Ref: https://github.com/i3/i3/pull/3834
* 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.
While an update was forced whenever polybar was made visible, the
`m_lastinput` variable was still set to the same value as when the bar
became hidden because updates to it were prevented.
Fixes#1875
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)
When adding a string to the builder directly, it would parse the string
for formatting tags, delete them and readd them with the methods in the
builder that keep track of open tags so that we can properly close them
when flushing.
This parser has a bug, it parses multiple formatting tags in a single
block as a single tag, e.g.
%{F#000000 u#FFFFFF +u}
would be parsed as an `F` tag with value `#000000 u#FFFFFF +u` which is
of course wrong.
Removing the parsing step fixes this problem in the simplest way
possible. This has two benefits:
* Building of modules is sped up because we don't have to do the parsing
step in the builder and many modules use this function to add strings
from a progressbar (which already has properly closed tags).
* We don't have parser logic in two places. Until now both `parser.cpp`
and `builder.cpp` actually parsed formatting tags. This leads to a lot
of code duplication and, as we've seen, bugs.
All of the modules that use this function to add text already make sure
that they properly close formatting tags (mostly by using the builder to
generate the strings)
NOTE: This change slightly changes polybar's behavior. Raw tags (tags
added by the user through the config) can now have their effects reach
neighboring modules because the builder doesn't track and thus doesn't
close them on each flush. This can (and will) be resolved by resetting
all tags at module borders.
Fixes#1555
There really is no reason to also close over/underline tags when we have
a right margin and a non-black over/underline color.
The git blame for these lines also doesn't give us any insights as to
why it was done this way.
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
To avoid polybar from being killed by SIGUSR1 during reloading, SIGUSR1 is ignored until the signal is registered in the new polybar process.
As stated in signal(7) man page, the ignored signals are still ignored after a call to a function of the execvX family.
During an execve(2), the dispositions of handled signals are reset to the default;
the dispositions of ignored signals are left unchanged.
Fixes#428
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.
Fixes#1532
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 idea is that pseudo-transparency should behave like real transparency as
much as possible. To achieve this, we now render the bar the same way in both
cases. The only part where pseudo-transparency differs is at the very end, where
the rendered bar is captured and composited against the desktop background
image. This should ensure that both modes behave the same.
This reverts some behaviour differences introduced by the pseudo-transparency
implementation. The new implementation is much closer to the
non-pseudo-transparent case and thus keeps original behaviour.
For the new method we simply fill the bar with the background image fetched from
the root window if in pseudo-transparent mode, otherwise we do nothing. This
means that everything will work as in the fully-transparent mode.
