Custom Gedit Syntax Highlighting

[ryuinferno-xda]

So I am trying to create a .lang file for GTK Source View:

<?xml version="1.0" encoding="UTF-8"?>

<language id="logcat" _name="logcat" version="2.0" _section="Others">
  <metadata>
    <property name="mimetypes">text/x-logcat</property>
    <property name="globs">*.logcat</property>
  </metadata>

  <styles>
    <style id="comment" _name="Comment"    map-to="def:comment"/>
    <style id="debug" _name="Debug" map-to="def:constant"/>
    <style id="info" _name="Info" map-to="def:string"/>
    <style id="warning" _name="Warning" map-to="def:type"/>
    <style id="error" _name="Error" map-to="def:identifier"/>
    <style id="fatal" _name="Fatal" map-to="def:error"/>
    <style id="others" _name="Others" map-to="def:string"/>
  </styles>

  <definitions>
    <context id="logcat">
      <include>
        <context id="comment" style-ref="comment">
          <start>---------</start>
          <end>$</end>
        </context>
    
        <context id="debug" style-ref="debug">
          <start>D\/</start>
          <end>$</end>
        </context>
    
        <context id="info" style-ref="info">
          <start>I\/</start>
          <end>$</end>
        </context>
    
        <context id="warning" style-ref="warning">
          <start>W\/</start>
          <end>$</end>
        </context>
    
        <context id="error" style-ref="error">
          <start>E\/</start>
          <end>$</end>
        </context>
    
        <context id="fatal" style-ref="fatal">
          <start>F\/</start>
          <end>$</end>
        </context>
    </include>>
  </definitions>
</language>

The sample of the file (.logcat) is as below:

--------- beginning of /dev/log/system 
I/auditd  (  145): Starting up 
I/Vold    (  141): Vold 2.1 (the revenge) firing up 
D/Vold    (  141): Volume sdcard0 state changing -1 (Initializing) -> 0 (No-Media) 
D/Vold    (  141): Volume sdcard1 state changing -1 (Initializing) -> 0 (No-Media) 
D/Vold    (  141): Volume usbdisk0 state changing -1 (Initializing) -> 0 (No-Media) 
--------- beginning of /dev/log/main 
I/installd(  153): installd firing up

And as you can see, the lines all start with "I/", "D/", "E/", "F/" or "W/", however I have read through the documentation for GTK Source View and found out that the <start> and <end> tags must contain regex expressions. So is there anyway to make it work? Thank you.

There are several things wrong with your language description file, primarily that the XML markup is broken. Perhaps you accidentally deleted a line?

In any case, I've fixed it and placed posted it as this gist on GitHub.
