ce93188a4a Add units support (POINT, PIXEL, SPACE) (#2578)
* add units support (POINT, PIXEL, SPACE) for polybar

- add a size_with_unit struct
- add a geometry_format_values struct
- move dpi initialisation from renderer.cpp to bar.cpp
- add a string to size_with_unit converter
- add point support (with pt)
- add pixel support (with px)

* Fix unit test compilation

* clang-format

* Better names

The old names didn't really capture the purpose of the structs and
function.

space_type -> spacing_type
space_size -> spacing_val

size_type -> extent_type
geometry -> extent_val

geometry_format_values -> percentage_with_offset

* Remove parse_size_with_unit

No longer needed. The convert<spacing_val> function in config.cpp
already does all the work for us and always setting the type to pixel
was wrong.

In addition, line-size should not be of type spacing_val but extent_val.

* Cleanup

I tried to address most of my comments on the old PR

* Fix renderer width calculation

We can't just blindly add the x difference to the width because for
example the width should increase if x < width and the increase keeps
x < width.

Similarly, we can't just add the offset to the width.

* Rename geom_format_to_pixels to percentage_with_offset_to_pixel

* Cleanup

* Apply suggested changes from Patrick on GitHub

* config: Use stod for parsing percentage

* Use stof instead of strtof

* units: Fix test edge cases

* Remove unnecessary clang-format toggle

* Use percentage_with_offset for margin-{top,bottom}

* Support negative extent values

* Rename unit to units and create a cpp file

* Move percentage_with_offset_to_pixel unit test to units

* Add unit tests for units_utils

* Clarify when and how negative spacing/extent is allowed

Negative spacing is never allowed and produces a config error.

Extents allow negative values in theory, but only a few use-cases accept
it.
Only the extent value used for the `%{O}` tag and the offset value in
percentage_with_offset can be negative. Everything else is capped below
at 0.

The final pixel value of percentage_with_offset also caps below at 0.

* Fix parsing errors not being caught in config

* Print a proper error message for uncaught exceptions

* Cleanup module::get_output

All changes preserve the existing semantics

* Stop using remove_trailing_space in module::get_output

Instead, we first check if the current tag is built, and only if it is,
the spacing is prepended.

* Remove unused imports

* Restore old behavior

If there are two tags and the second one isn't built (module::build
returns false), the space in between them is removed.
For example in the mpd module:

format-online = <toggle> <label-song> foo

If mpd is not running, the mpd module will return false when trying to
build the `<label-song>` tag. If we don't remove the space between
`<toggle>` and `<label-song>`, we end up with two spaces between
`<toggle>` and `foo`.

This change is to match the old behavior where at least one trailing
space character was removed from the builder.

* Add changelog entry

* Remove unused setting

* Use percentage with offset for tray-offset

28af6bb493 Fix race condition when creating socket folder
If two processes call `mkdir` at the same time, the second one will fail
and wrongly assume the folder wasn't created properly.

We now first check if the folder really doesn't exist and we also catch
any IPC initialization errors and disable IPC instead of crashing the
whole bar.

* ipc: Handle wrong message types

* ipc: Write back error message if ipc message cannot be processed

This only happens for commands and empty actions.
Non-empty actions are not immediately executed, but deferred until the
next loop iteration.

* Remove TODO about deleting runtime directory

The socket file is not deleted after socket.close() is called, only
after libuv executes the close callback.
So we can't just call rmdir because it will probably always fail.

151a263654 fix(monitor): do not include outputs when monitors are supported (#2485)
* fix(monitor): do not include outputs when monitors are supported

Previously, when splitting an output into two monitors, `polybar -m`
would report both the splitted monitors and the output. This was not
caught by the the clone detection as the detection works by removing
monitors contained into another monitors (and monitors were excluded
from that logic) and we want the other way around: outputs covered by
monitors should be ignored.

Instead of trying to detect covered outputs, the solution is quite
simple: when monitors are supported, do not consider outputs, unless
we request all outputs. A monitor can be set primary (and RandR
reports primary outputs as primary monitors). The only information we
would miss from monitors are things like refresh rate and EDID. We
don't need that, so we are fine.

As monitors are only created for connected output (and they are in
this case "active") or disconnected output if they are mapped (and
they are in this case "inactive"), I am a bit unsure if we have
exactly the same behaviour as previously when `connected_only` is set
to `false`.

As some modules require an output, we keep the output in the
`monitor_t` structure and we ensure it is correctly set when using
monitors. A monitor can have 0 or several outputs. We only handle the
0 and 1 cases. When a monitor has more outputs, only the first one is
used. AFAIK, only the xbacklight module needs that and I think we are
fine waiting for a user needing this module and merging monitors.

The C++ binding fail to expose the `outputs()` method to iterate over
the outputs of a monitor. This seems to be a bug in XPP. The field is
correctly defined in the RandR XML file and it works with the Python
binding.

```xml
	<struct name="MonitorInfo">
		<field type="ATOM" name="name" />
		<field type="BOOL" name="primary" />
		<field type="BOOL" name="automatic" />
		<field type="CARD16" name="nOutput" />
		<field type="INT16" name="x" />
		<field type="INT16" name="y" />
		<field type="CARD16" name="width" /> <!-- pixels -->
		<field type="CARD16" name="height" /> <!-- pixels -->
		<field type="CARD32" name="width_in_millimeters" />
		<field type="CARD32" name="height_in_millimeters" />
		<list type="OUTPUT" name="outputs">
		    <fieldref>nOutput</fieldref>
		</list>
	</struct>
```

Falling back to C only to access the list of outputs is not enough
because the list is appended to the structure and not visible through
the public API. When copied, the structure loses the list of monitors.

Also, change the mention "XRandR monitor" to "no output" when there is
no output attached. People using monitors know what it means and it is
useful to catch a future regression where we don't have an output at
all (which would break the brightness plugin).

Fix #2481

* Update CHANGELOG.md

56e24992df config_parser: Introduce stricter syntax conventions (#1377)
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 #1032
Closes #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

20f3d9a141 refactor: Don't initialize forward declared members
Using brace initialization here causes bar.hpp to not compile when

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
