Second More Useless Plugin
Bored again which seems to be the usual for the summer I sat down with one purpose in mind: To write another plugin. Didn't really matter to me if it was useful or not I just wanted to write another one. I decided to ask my friend Pete who snarkily replied "Write one that randomly inserts horse pr0n[1] in your blog." to which I immediately replied "not horse pr0n, ASCII pr0n!" which probably made him choke on his drink and immediately remember rule 34. But this made me think to myself: Why not a random plugin?
So I did just that, I wrote a random plugin. One so useless that I don't think I'm even going to activate it on my blog save for days like April Fools Day. The plugin chooses at random a word from each post using the the_content hook and censors it out with <censored>. Funny huh? This will ignore html tags so it won't break links and things like that. The code is as follows:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | <? /* Plugin Name: Random Censor Plugin URI: http://www.bemasher.net/ Description: Picks a common word at random from posts at display and replaces with <censor>. Ignores urls and other semi-important things. Version: 0.01 Author: BeMasher Author URI: http://www.bemasher.net/ */ function random_censor($content) { $oldcontent = $content; $content = preg_replace("/<[^<]+?>/", "", $content); preg_match_all("/\b\w+\b/", $content, $words); $word = $words[0][rand(0, sizeof($words[0]))]; $oldcontent = preg_replace("/\b$word\b/i", " <censored> ", $oldcontent); return $oldcontent; } add_filter("the_content", "random_censor"); ?> |
- Mind you this is a joke, relating to the fact that horse pr0n happens to rank pretty high on the list of strange things on the internet. [↩]
My First WordPress Plugin
I've been meaning to do this for a while, I'm writing a plugin for wordpress to automatically capitalize the right letter in the words I'm generally lazy about typing. Things like I, I'm, I've and the like[1].
Took me a little while but I did finally find some documentation on all the different hooks wordpress has for filters. I found one in particular that does what I want called content_save_pre which applies a particular filter to the content of a post any time I save or edit it. So for things like drafts and actual posting and updating posts it would fire the function I registered as a filter.
The first problem I ran into is that for some strange reason it didn't seem to want to replace contractions with the single quote character. I later found out that when displaying the single-quote it converts it to the html entity ’ which shows up as an apostrophe. So I tried working around that but that dIdn't seem to work either. Eventually I just setup a small test post and modified the function to email me the plain-text contents of the post that the filter would receIve, I noticed that it escaped single quotes probably through the use of the php function mysql_escape_string[2]. So anything with an single-quote would show up with a backslash just before the single-quote. This of course broke the regular expression I was using and I couldn't seem to figure out how to get it to check for that character so I gave up and just used the negated word-character class \W.
Anyway after fiddling around with it a little more and adding a few new cases to the regex I arrived at this code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | <?php /* Plugin Name: Lazy Errors Plugin URI: http://www.bemasher.net/ Description: Replaces errors from lazy typing, things like: I, I'd, I've, I'm will be replaced with proper case. Version: 0.02 Author: BeMasher Author URI: http://www.bemasher.net/ */ function lazy_errors($content) { return preg_replace("/I(?(?=\W')(\W')(ve|m|d|)|(\b))/", "I$1$2$3", $content); } add_filter("content_save_pre", "lazy_errors"); ?> |
The regular expression reads like so: If there's an I followed by any non-word character and a single-quote then make sure it's got a proper contraction following the single-quote. Else make sure there's a space, period, comma, colon or semI-colon following the I. Then replace with capitalized I and the matching group from the conditional.
I should probably work out some code to make it ignore sections of text I don't want it to filter. A prime example of this would be in the comments of the plugin and especially in any code as code examples copied from my site would then be broken if the regex I wrote matched anything in the code.
