This adds the option `content_alignment`, which allows the user to set
the vertical alignment of the notification's content (i.e. icon and
text) to either top (`CONTENT_TOP`), center (`CONTENT_CENTER`, default),
or bottom (`CONTENT_BOT`). The default preserves current behaviour,
while the other options fulfill #486.
Sometimes these parse functions can have other side-effects such as the
sepcolor one which defaults to a custom color string if the value is
unknown. If the string is empty all of these functions should fail to
allow for the default to be used.
See #649 for details
Quoted values can still have a trailing comment that we need to remove
before calling `add_value`. Otherwise, when trying to strip the quotes
from the value `string_strip_quotes` only looks at the end which
is inside the comment and so it won't find a matching end quote to
strip.
Fixes#626
Changes all string parsers to have a the almost same interface while
also having a proper return value, which indicates success of the
parsing process.
Just recently, I started using g_return_val_if_fail as a brief assertion
checker. It'll also exit the function with a specified return value.
But actually this introduces some weird behavior. It's configurable by
environment variables and it'll print out a log message, if the
expression didn't validate properly. But some of these assertions are
actually ment to be silent.
Using a simple macro makes it simple to structure the assertions and its
return values in a block at the start of a function or anywhere else.
Previously config lines like
[rule]
script = mail -s "New notif"
were only possible to get written with additional full quotes,
which makes no sense in command line expressions.
After some research, the _GNU_SOURCE does not affect any function call
anymore. To avoid future failures on other systems not using glibc,
_GNU_SOURCE gets removed.
It's hard to trace back, which methods in option parser require freeing
the result and which prohibit it. Marking all non-freeable values as
const lets this problem solve the compiler.
To achieve a consistent scheme, all stars of the
pointers should be on the side of the variable and
not on the side of the type.

A lot of error reporting used a simple `printf` call which by default
prints to stdout. This was changed so that all error reporting is done
by an `fprintf(stderr, ...)` call.
According to the glib memory allocation documentation, if any memory
allocation calls fail the application will be terminated so there is no
need to check if the call succeeded.
To load each line of the configuration file we were previously using a
simple buffer of length BUFSIZ. BUFSIZ is a macro provided by glibc as
the 'recommended length for a buffer'. But since one of our users
encountered a situation where really long config lines were necessary
it's time to change that behaviour.
This commit changes the line reading from using fgets with a character
limit of BUFSIZ to simply using getline.
We initialize the buffer pointer to NULL since getline will
automatically allocate a big enough buffer for us if it's passed a NULL
pointer. After that we pass the same buffer pointer again since,
according to the getline manpage, getline will also call realloc on the
buffer if necessary. Which means the only thing we have to do is call
free() at the end of the parsing process.
Fixes#294
This mostly means using strchr, but I also found:
option_parser.c:load_ini_file:
- replace multiple calls to strstr with strpbrk
notification.c:notification_init:
- replace string_replace in a while loop with a single call to
string_replace_char
redo string replace all
