SyntaxHighlighter is quite a nice wordpress plugin that provides syntax highlighting for a range of programming languages (among them my favorites python & C#). the problem is, in its original unadulterated form it doesn’t play with my favorite markup plugin php markdown extra at all

after quite a bit of hacking, it transpires that one can make them play nicely with one another. the idea that i pursued was to change the tag to < source lang=XXX> and have php markdown treat it the same as the < pre> tag.¹

getting markdown extra to recognize the < source> tag is fairly easy², i needed to change # Tags treated as block tags only if the opening tag is alone on it’s line: var $context_block_tags = ’script|noscript|math|ins|del’; to read # Tags treated as block tags only if the opening tag is alone on it’s line: var $context_block_tags = ’script|noscript|math|ins|del|source’;

next, in the syntax plugin, all occurrences of [source: are replaced by < source lang=.

i’ve created ZIP files of the modified SyntaxHighlighter and Markdown Extra plugins, share and enjoy.

yesterday i updated the wordpress plugins on our d2h.net and xyzzyxyzzy.net blogs. once done, both blogs would not work anymore…duh! the updated geopress plugin was borked — or so it seemed…

…it turned out that i had added code to the earlier version of geopress to do pretty printing of coordinates, and, of course, the update flushed that code down the drain. thanks to a regular backup running on our web server, however, that code was not gone forever. here are the functions that i added:

function the_geo_coord() { $coord = the_coord(); $coord = str_replace(‘ ‘, ‘,’, $c); return $coord; }

the_geo_coord() gets the coordinates via geopress’s the_coord() function and simply substitutes commas for spaces.

likewise,

function the_geo_pretty_print() {

$coord = the_coord(); $coord = split(” “, $coord);

$coord_lat = intval($coord[0]); $coord_lon = intval($coord[1]); $coord_lat_min = intval(($coord[0] – $coord_lat) * 60); $coord_lon_min = intval(($coord[1] – $coord_lon) * 60); $coord_lat_sec = intval(((($coord[0] – $coord_lat) * 60) – $coord_lat_min) * 60); $coord_lon_sec = intval(((($coord[1] – $coord_lon) * 60) – $coord_lon_min) * 60);

if (0 <= $coord_lat) { $coord_lat = ‘N ‘ . $coord_lat; } else { $coord_lat = ‘S ‘ . abs($coord_lat); }

if (0 <= $coord_lon) { $coord_lon = ‘E ‘ . $coord_lon; } else { $coord_lon = ‘W ‘ . abs($coord_lon); }

$coord_tag = “$coord_lat° $coord_lat_min’ $coord_lat_sec\”, $coord_lon° $coord_lon_min’ $coord_lon_sec\”";

return $coord_tag;

}

takes geopress’s the_coord() and pretty-prints it as human readable “old-style” latitute–longitude coordinates. the_geo_coord_esc() finally, produces a URL escaped longitude–latitude coordinate for use inside a, well, URL:

function the_geo_coord_esc() { $q = the_geo_pretty_print(); $q = str_replace(‘”‘, ‘%22′, $q); $q = str_replace(‘\”, ‘%27′, $q); $q = str_replace(‘ ‘, ‘+’, $q);

    return $q;

}

just add those PHP functions to geopress/geopress.php, shake, stir, and save.
