From: Carl Worth Date: Tue, 13 Oct 2009 14:23:14 +0000 (-0700) Subject: Add sup-compatible prefixes and achieve sup-compatible print output X-Git-Tag: 0.1~898 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=5986cfe5e71bad6126a05e733fa9ea777d7cc0eb;p=notmuch.git Add sup-compatible prefixes and achieve sup-compatible print output What I've done here is to instrument sup-sync to print the text and terms objects it constructs just before indexing a message. Then I've made my g_mime_test program achieve (nearly) identical output for an example email message, (just missing the body text). Next we can start shoving this data into a Xapian index. --- diff --git a/g_mime_test.c b/g_mime_test.c index eb624b69..9ffb0ac1 100644 --- a/g_mime_test.c +++ b/g_mime_test.c @@ -21,18 +21,128 @@ #include #include #include +#include #include #define ARRAY_SIZE(arr) (sizeof (arr) / sizeof (arr[0])) +/* These prefix values are specifically chosen to be compatible + * with sup, (http://sup.rubyforge.org), written by + * William Morgan , and released + * under the GNU GPL v2. + */ + +typedef struct { + const char *name;
