626c55f8e5 Template value type for get_with_prefix 2021-09-28 22:16:07 +02:00
TheDoctor314
1e0e50266b Add get_with_prefix()
Returns a list of key-value pairs starting with a prefix.
If you have in config:
```
env-FOO = bar
env-CAT = dog
```

then `get_with_prefix("env-")` will return
`[{"FOO", "bar"}, {"CAT", "dog"}]`

dd4088910e Deprecate throttle-output and throttle-output-for
The eventloop no longer uses them. libuv will coalesces multiple
uv_async_send if they happen one after another and this also leads to
coalescing of updates.

This is needed because the handle's lifetime has to be at least the

Universal Visibility Action (#2320 cont'd) (#2426)
* Add toggle_visible action

* Add set_visible and set_invisible actions

* Rename toggle_visible method to match

`action_toggle_visible` -> `action_toggle_visibility`

Matches with `EVENT_TOGGLE_VISIBILITY`

* Update CHANGELOG

* Revert #2320 IPC commands

IPC commands are no longer necessary now that the actions are
implemented. Changed some method permissions as well to reflect this.

* Add logging and change action names

- `module_toggle`
- `module_show`
- `module_hide`

Delineate common actions to all modules with a `module_` prefix (for
future actions too)

* Update documentation

Add initial support for an escape character (#2361)
Add a config parser method which, for now, deals only with escaping the
literal backslash character and logs an error message to inform the user
of the coming change.

The error message includes a properly escaped value for the user.

As a result of introducing an escape character('\'):

  - Warn the user of any unescaped backslashes, as they will not be
    treated as a literal character in the future

  - For now, still treat a single backslash as a literal character

  - Treat two consecutive backslashes as a single properly escaped
    literal backslash

Also:
  - Add documentation about the escape character to polybar(5) manpage
  - Add info about the escape character to changelog
  - Add testcases for ParseLineKeyTest
  - Add new test ParseEscapedValueTest

Resolves: First step in #2354

Improve value parsing

 - Take value arg in as an rvalue reference and move parsed value back
 - Remove unnecessary if statement
 - Rename function
 - Improve error message
 - Improve function description
 - Format

eaa50691fc fix(config_parser): UB in logger
Because we passed a temporary as the logger, it gets destroyed after the
config_parser constructor returns and when the logger is called in
config_parser it operates on a dangling reference.

Add compiler warning for missing override specifier (#2341)

We should always use the override specifier when overriding virtual
functions. This helps prevent errors when a subclass tries to create a
function with the same name as a virtual function in a super-class but
with a different purpose.

* Upload logs on failure

* Add override to unsupported.hpp

feat: Module Visibility (#2320)
Modules can now also be shown and hidden using ipc commands:

    $ polybar-msg [-p PID] cmd hide.mymodule # Hides module mymodule
    $ polybar-msg [-p PID] cmd show.mymodule # Shows module mymodule
    $ polybar-msg [-p PID] cmd toggle.mymodule # Toggles visibility of mymodule

* Hopefully implement visibility checking

* Implement hide command

* Implement `show` and `toggle` commands

* Refactor and add some logging

* Run style checks and update CHANGELOG

* Get around unused parameter warnings

* Change `set_visible` to return nothing

* Make errors more informative

Co-authored-by: Patrick Ziegler <p.ziegler96@gmail.com>

* Update bar when changing module visibility

- Called in the module to maintain dependence on the signal emitter
- Update CHANGELOG to make changes more verbose

New Tag Parser (#2303)
* refactor(color): Use enum class for color type

* Add testcases for tag parser

* Make tag parser a pull-style parser

Being able to parse single elements at a time gives us more fine-grained
error messages, we can also parse as much as possible and only stop
after an exception.

* fix(color): Parser did not check for invalid chars

* tag parser: First full implementation

* tag parser: Fix remaining failing tests

* tag parser: Replace old parser

* tag parser: Treat alignment as formatting tag

Makes the structure less complex and the alignment tags really are
formatting tags, they are structurally no different from the %{R} tag.

* tag parser: Cleanup type definitions

All type definitions for tags now live in tags/types.hpp, the parser.hpp
only contains the definitions necessary for actually calling the parser,
this shouldn't be included in many places (only places that actually do
parsing). But many places need the definitions for the tags themselves.

* Rename components/parser to tags/dispatch

* tag parser: Cleanup

* Add changelog

54e2490aa5 fix(logger): Wrong conversion function called
For some reason when passing some non-const strings to convert, the
convert(T&& arg) method was used instead of the one specialized for
strings.

This caused an error in clang because you can't pass objects with
non-trivial types to varargs functions.

The best solution I found was to just add a specialized function for
non-const strings.

52eee95bf8 controller: Detach shell commands from polybar
Shell commands triggered from action tags used to block polybar until
they finished.

Since we are not actually interested in the output of the commands, it
makes sense to run them completely detached from polybar and have
polybar not block when executing these commands.

Now the spawned child processes no longer get killed when polybar
exits. This is fine because polybar is not responsible for these
processes since they were explicitly started by the user through click
commands.

refactor: Deprecate throttle-input-for setting (#2117)
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.

3f60561ae3 logger: Downgrade some warning messages
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`

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.

51184c7ead ipc: Remove unused global setting
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).

587dc6c84d bar: Make module separator a label
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.

fea579ec85 fix(bar): Configure window before remapping
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.

controller: Print error for duplicate modules (#1534)
* 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.

57d364a2fc Reset all tags at the end of a module
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)

3ebb0b0b03 builder: Simplify open tag tracking
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

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

e793082008 randr: Add separate key for exact monitor matching
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.

7256366112 fix(tray): correctly handle transparency when using offset (#1571)
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})
