    <h2>
       Lexer addition.
    </h2>
     <p>This document assumes you know how to create a lexer.&nbsp; It only 
		covers information specific to making the changes necessary for that 
		lexer to work as an external lexer.</p>
<p>The lexer must export 4 functions (On Windows, it is necessary to create a 
module definition file to export the symbols correctly).&nbsp; Below are the 
proto-types for those functions (ExternalLexer.h must be included so that 
EXT_LEXER_DECL can be resolved):</p>
<p>void EXT_LEXER_DECL Lex(unsigned int lexer, unsigned int startPos, int 
length, int initStyle, char *words[],<br>
&nbsp;&nbsp;&nbsp; WindowID window, char *props);<br>
int EXT_LEXER_DECL GetLexerCount();<br>
void EXT_LEXER_DECL GetLexerName(unsigned int Index, char *name, int buflength);<br>
void EXT_LEXER_DECL Fold(unsigned int lexer, unsigned int startPos, int length, 
int initStyle, char *words[],<br>
&nbsp;&nbsp;&nbsp; WindowID window, char *props);</p>
<p>Lex - This function is called whenever lexing needs to be done.&nbsp; The 
first thing you may notice is the lack of an Accessor object to style with.&nbsp; 
A WindowAccessor object can be created from the WindowID and props objects.&nbsp; 
A PropSet object must be created from props, first, then that PropSet and the 
WindowID are used to create a WindowAccessor.&nbsp; You will also need to create 
your own WordList.&nbsp; (The last row in the words array is a NULL pointer, so 
you can safely read 1 past the last row to determine how many rows there are).&nbsp; 
Once you have the WordList and Accessor, you can pass them to your lexing 
function just like using a built-in lexer.&nbsp; The only other difference is 
you need to call Accessor::Flush() sometime before Lex returns, or not all text 
may be updated.&nbsp; This is due to Scintilla's buffering.</p>
<p>GetLexerCount - This returns the number of individual lexers you want to 
export from your module.</p>
<p>GetLexerName - Fill in the name field with the name of the lexer.&nbsp; This 
is how it is later identified in SciTE properties.</p>
<p>Fold - The function called whenever SciTE requests folding be performed.&nbsp; 
The same information found in Lex for creating a WindowAccessor apply here, too.</p>
