[Fontconfig] RE: Specifying location of fontfiles in fonts.conf file.

[Rupa Kamoji]

Hello,

I am new to fontconfig. I am not aware of source code of fontconfig.
Where should I write this piece of code? 

One more way is to specify the path with environm,ent variable in
fonts.conf file right? On line number 26 in fonts.conf file, there is a
list of directories in which fontconfig is searching for the font files.
I want to write some something like below in fonts.conf file.

<dir>$MYFONTFILES/fontfiles</dir>

Where $MYFONTFILES is an environment variable which has
/mydisk/usr/home/mysettings directory path assigned to it .

Instead of 

<dir>/mydisk/usr/home/mysettings/fontfiles</dir> on line no. 26 in
fonts.conf file.

Thanks a lot for your response.



Thanks and Regards,
Rupa.

The code does not presently support the use of arbitrary environment 
variables and I'm not sure if there might be any security implications 
from doing so.

However, if you want your shipped copy of fontconfig to use an 
environment variable, then you can write a quick and dirty hack to, for 
instance, FcConfigAddDir.  Add something like the following lines:

	if (strcmp(d, "$CUSTOM_FONT_DIR") == 0)
		d = (FcChar8 *) getenv ("CUSTOM_FONT_DIR");

I think that'll work for your case.
