Trimming the quotes in labels and the date module are not needed at all,
because surrounding quotes are removed when loading the values from the
config.
Removing the quotes in the builder also doesn't seem to serve any
purpose at all.
The check of the maxlen and ellipsis condition was also moved to the
label creation, this way get_label_text doesn't need to care about the
restrictions placed on maxlen and ellipsis
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)
Fixes#1201
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.
Build the format sub-strings (%fill%, %indicator%, %empty%)
before adding it to the builder to avoid having it generate
alot of duplicate content (tags, etc)
Make it possible to set different size
and color values for the two properties.
`overline-size = 2`
`overline-color = #f00`
`underline-size = 5`
`underline-size = #00f`
