    <p>I found it a bit daunting when i started with my lexer but everything boils down to a few important ideas:</p> <ul> <li>Put lexer in lexer folder</li> <li>Tell scintilla about the lexer you added</li> <li>Add your constants to scintilla.iface</li> <li>Tell scintilla about your own Constants (if you use any)</li> <li>Code/Compile + Repeat until satisfied</li> </ul> <p>An actual example is:</p> <p>After you create your Lexer Template you name it LexNEW.cxx</p> <ul> <li>Put LexNew.cxx in <code>/lexers</code> folder</li> <li>Enter in <code>/src</code> and run <code>LexGen.py</code>, this tells scintilla that there is a new lexer by adding it to Scintilla.h</li> </ul> <p>Now you add your constants to the .iface file. The most important ones are: <code>val SCLEX_NEW=108</code> where <code>108</code> is an unused id number and <code>lex new=SCLEX_NEW SCE_NEW_</code> where <code>new</code> is a valid unique short identifier for your lexer.</p> <p>Put them in the same sections as the others (to avoid confusion later on) and if in doubt use one of the other definitions as a template!</p> <p>Now below your <code>lex new=</code> line you can define your own constant values like:</p> <pre><code>val SCE_NEW_DEFAULT=0 val SCE_NEW_COMMENTLINE=1 val SCE_NEW_COMMENTBLOCK=2 val SCE_NEW_ERROR=31 </code></pre> <p>After this step you are almost ready.</p> <ul> <li>Enter in <code>/include</code> and run <code>Hface.py</code> which tells scintilla about your new constants.</li> </ul> <p>If your lex code is valid then you are ready to compile.</p> <p>Remember to repeat that last step every time you create a new constant. The <code>HFace.py</code> script adds those values to SciLexer.h which you can do manually if you prefer not to do two steps every time.</p> <p>And thats it my friend after compiled make sure your program sets your lexer with something like: <code>sci.SetLexer(108)</code> and put some colors to each state like <code>sci.StyleSetFore(01, 0x008800) // SCE_NEW_COMMENTLINE</code> and so on.</p> <p>One last thing you will want to use <code>SciLexer.dll</code> which is the one that contains all lexers not <code>scintilla.dll</code> Good luck!</p>
