Adds a variable to specify the location where the font will be installed.
In this patch I chose to use /usr/share/consolefonts as the default,
though on my openSUSE system it will be /usr/share/kbd/consolefonts.
Maybe it varies between distros, so its good to have a variable.
Example usage:
FONT_DIR="/usr/share/kbd/consolefonts" ./configure && make && make install
Fixes https://github.com/karlstav/cava/issues/147
nested functions in pulse.c where removed,
but pa_mainloop had to be declared globaly
in order to close loop after finding default sink name
this might cause more problems in the future.
Hex colours will be used only if the terminal supports color redefinition,
otherwise default colours will be used.
This means that no error of any kind will be shown to the user in such cases.
**NOTE: This breaks the `b` and `c` keys for cycling through the colors
in ncurses mode.**
Added a new function in cava.c `int validate_color(char
*colourToValidate, int outputMode)` which returns 1 is the colour is
valid, 0 otherwise.
Validation is done to ensure that HTML colours are of the form `#xxxxxx` or a
named ncurses colour is present.
HTML colours are allowed only when output mode is ncurses (ie `om = 1 ||
om = 2`). HTML and named colours can be mixed.
If the output mode is other than ncurses, the old method of setting
`bgcol` and `col` will be used.
Added a function in `terminal_ncurses.c` called `struct cols
parse_color(char *col)` which returns a struct containing:
1. `col`: The ncurses colour number parsed.
2. `R`, `G` and `B`: Integers that represent the R, G and B values
parsed.
The `init_terminal_ncurses()` method now accepts two character pointers
instead of integers. The pointers contain color names (either HTML or
ncurses names) which are then parsed by the parse function defined
above.
Currently there is no check to find if the terminal supports color
redefinition or not. According to the parsed value we decide whether to
perform redefinition or use the predefined ncurses colours.
Ncurses colours 1 and 2 are redefined for foreground and background
respectively. This means that upon exiting, all the occurrences of 1 and
2 would have been redefined. To fix the colours back to the original the
user has to open another terminal.
