Woo hoo! Bug free the first time through …
It's always nice when code I write works the first time.
mod_blog advancing yet some more. I was going to embed the HTML within the
module, but when I wrote some sample code (to make the archives on the
current site) it just got real messy real quick and I didn't even bother
finishing it up.
Instead, I quickly wrote code to process template files. This side works
pretty much like I think I'm going to end up doing it. I set up a
subdirectory containing the templates, each file containing just a portion of
a much larger page. In effect, each file is a chunk of HTML code that is
processed. During the processing, anything between double hash signs is taken
as the name of a callback function.
So for example, in the HTML code I have:
-----[ HTML ]-----
<html>
<head>
<title>##title## - The Boston Diaries - Captain Napalm<title>
</head>
-----[ END OF LINE ]-----
And the callbacks are currently defined in C as such:
-----[ C ]-----
static void archive_callback(FILE *fpout,void *data)
{
struct tm *ptm = data;
char date[BUFSIZ];
strftime(date,BUFSIZ,"%B %Y",ptm);
fprintf(fpout,"%s",date);
}
/***************************************************/
void do_archive(
FILE *fpout,
int year,
int month,
int stday,
int endday)
{
static struct chunk_callback cb
= { "title" , archive_callback };
struct tm thisday;
/* code to set thisday properly snipped */
ChunkProcess(fpout,"archivehead",&cb,1,&thisday);
ChunkProcess(fpout,"bostontitle",NULL,0,NULL);
ChunkProcess(fpout,"bartitle",&cb,1,&thisday);
/* code to generate links for each day */
ChunkProcess(fpout,"end",NULL,0,NULL);
}
-----[ END OF LINE ]-----
The call to ChunkProcess() takes an output file, the name of the chunk to
display, a structure declaring the callbacks, the size of that array, and an
extra pointer that is passed to the callback, in this case, to a struct tm *
to the date we're processing.
The only thing I may change is the way callbacks are registered, but the
mechanics certainly work.
