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

33e691301d fix(config): Don't treat an empty value as invalid (#2315)
An empty color value in the config should be treated as if no color was
specified (explicitly). This is the same behavior as before.

b2c515c73c fix(config): Reintroduce multiple inheritance (#2271)
Pre 3.5.0, any key starting with 'inherit' was treated as an inherit
directive. This allowed for multiple inheritance even though it was
never inteded in that way.
3.5.0 removed that bug/feature by doing a strict check against 'inherit'

It seems people were relying on this behavior, so we are adding it back.
However multiple inheritance with multiple keys is also deprecated in
favor of the `inherit` key now supporting multiple space separated
sections.

This is because the config doesn't have a key order, but inheritance
does depend on the order the different section keys are copied over (if
multiple inherited sections define the same key).

Fixes #2269

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

095d68fad0 fix: Stop using ato* for string to num conversion
atoi, atof and so on have undefined behavior if anything goes wrong. We
now use strto*, but without error checking. In most places overflows and
the like *should* not happen. String to number conversions are only used
when reading data from other applications or from the config, if another
application gives unparsable strings or too large numbers, then most
likely there is something wrong with that application. If the error
comes from the user config, then the user has to live with values
provided by strto* on error (which are very reasonable)

30f516dd7d fix(formatting): Make formats parse specs as-is
This removes the spacing tinkering when parsing format specs.
The following example uses the old behavoir:

    format-test = <label-foo>  <label-bar>
    format-breaks = <label-foo><label-bar>/<bar-test>

`format-test` would replace all occurences of ' ' with the
a space string with defined `spacing` as its width. `format-breaks` would
not validate as the tags where split with ' ' as delimiter.

All that nonsense has been removed and each tag is extracted as is.
The `spacing` parameter can still be used to apply N extra whitespaces
between the tags, but it is now 0 by default.
