Blog Refreshed Part Two
This a shorter post, and maybe more of just a Mango Blog plugin post.
So in part one I went of the tweaks that I made to help me for entering and editing blog posts. Now I will show you what I did to fixed the code formatting. Again I created a plugin, the plugin that I created using coldFish(coldfish.riaforge.org) to format the code in my blog entries. Here is my plugin xml.
2<plugin id="com.asfusion.mango.plugins.coidFish" name="Cold Fish" version="0.1" provider-name="Think-lab" class="coldfish.Handler">

10 <event name="postGetContent" type="synch" priority="1" />
11 </listens>
12</plugin>
This plugin listening for the "postGetContent" event.
Now time for the handler code. In the init function we are setting "variables.coldfish" equal to the coldFish component.

3 <cfargument name="mainManager" type="any" required="true" />
4 <cfargument name="preferences" type="any" required="true" />
5
6 <cfset setManager(arguments.mainManager) />
7 <cfset setPreferencesManager(arguments.preferences) />
8
9 <cfset variables.coldfish = createObject("component","coldfish").init()/>
10 <cfreturn this/>

In the processEvent function I am using some code from BlogCFC from the blog component renderEntry function, thanks Ray. The only thing that I really want to point out in the function below is how I am overriding the content variable which is where the blog post is stored "arguments.event.accessObject.content". Also in the code below added spaces within the < code > tags for this post only.
2 <cfargument name="event" type="any" required="true" />
3
4 <cfset var eventName = arguments.event.getName() />
5 <cfset var data = "" />
6 <cfset var newBody = "" />
7 <cfset var tmpContent = "" />
8 <cfset var newContent = "" />
9 <cfset var counter = 0 />
10 <cfset var codeblock = "" />
11 <cfset var codeportion = "" />
12 <cfset var result = "" />
13
14
15 <cfif eventName EQ "postGetContent" OR eventName EQ "postGetExcerpt">
16 <cfset data = arguments.event.accessObject />
17 <cfset tmpContent = data.content />
18
19 <!--- Check for code blocks --->
20 <cfif findNoCase("start_code",tmpContent) and findNoCase("< / end_code >",tmpContent)>
21 <cfset counter = findNoCase("< start_code >",tmpContent)>
22 <cfloop condition="counter gte 1">
23 <cfset codeblock = reFindNoCase("(?s)(.*)(start_code)(.*)(</ end_code >)(.*)",tmpContent,1,1)>
24 <cfif arrayLen(codeblock.len) gte 6>
25 <cfset codeportion = mid(tmpContent, codeblock.pos[4], codeblock.len[4])>
26 <cfif len(trim(codeportion))>
27 <cfset result = variables.coldfish.formatString(trim(codeportion))>
28 <cfset result = "< div class='code' >#result#< /div >">
29 <cfelse>
30 <cfset result = "">
31 </cfif>
32 <cfset newbody = mid(tmpContent, 1, codeblock.len[2]) & result & mid(tmpContent,codeblock.pos[6],codeblock.len[6])>
33
34 <cfset tmpContent = newbody>
35 <cfset counter = findNoCase("start_code",tmpContent,counter)>
36 <cfelse>
37 <!--- bad crap, maybe < start_code > and no ender, or maybe < / end_code >< start_code > --->
38 <cfset counter = 0>
39 </cfif>
40 </cfloop>
41 <cfset data.content = tmpContent />
42
43 </cfif>
44 </cfif>
45
46 <cfreturn arguments.event />
