Okay, I've added a new option to configure. --config-buffer-size=NNNN
will set the theme parser's line buffer size. What does this mean?
Well, this determines how big a line being parsed can get at any one
stage of parsing. So if you use %dirscan() on a large directory, or
you use %random() on a large list, or you simply have some very large
lines in your config file, making this buffer size larger will enable
them to be handled. The down side to this is that your Eterms will
appear to take up more memory. In reality they don't, since all that
memory gets freed, but it isn't returned to the OS until Eterm exits,
and the RSS won't go down unless part or all of Eterm is swapped out
by the OS. So you've been warned. :-)
For those who didn't go digging by themselves, what I added yesterday
were three new builtin functions:
%get(variable) Retrieves the value of a theme variable
%put(variable value) Sets the value of a theme variable
%put(variable) Removes a theme variable
%dirscan(directory) Returns a list of the files in a directory
Everything here should be fairly self-explanatory. The variables
are internal to Eterm. They will last until Eterm exits, so you
can refer to them in later theme files, unless of course you call
%put() with a variable but no value (which removes the variable).
Also note that %dirscan() returns only the filenames, not the
full pathnames. This is for two reasons: One, you already know the
path to the file since you specified it. Two, it enables handling of
directories with larger numbers of files since the path isn't
uselessly duplicated for each entry it generates.
These new functions will be the backbone for a new random background
system since the *.list files are rather clumsy in a lot of ways. I
am not yet sure how it will work exactly, but I know I'll need these
functions to do it. :-)
