<p>I've used lex and yacc (more usually bison) in the past for various projects, usually translators (such as a subset of EDIF streamed into an EDA app). Additionally, I've had to support code based on lex/yacc grammars dating back decades. So I know my way around the tools, though I'm no expert.</p>

<p>One major difference is that ANTLR generates an LL(*) parser, whereas YACC and Bison both generate parsers that are LALR. This is an important distinction for a number of applications, the most obvious being operators:</p>
<pre><code>expr ::= expr '+' ... | <p>Another advantage of ANTRL is that you can use <a href="http://www.antlr.org/works/index.html" rel="noreferrer">ANTLRWORKS</a>, although I can't say that this is a strict advantage, as there may be similar tools for other generators as well.</p>

<p>When logging with Log4Net it's very easy to put class that called the log into the log file. I've found in the past that this makes it very easy to trace through the code and see the flow through the classes. In Log4Net I use the %logger property in the conversion pattern like so: </p>
