Body
<p>I am learning parsing, bison & lex. I am looking for a clear & complete tutorial/example that demonstrates all of:</p> <ol> <li>C++ (not C) Abstract Syntax Tree.</li> <li>Re-entrant lexer.</li> <li>Re-entrant parser.</li> <li>Reading from a string (vs. from file) would be nice as well.</li> </ol> <p>I have found multiple examples and tutorials, but each typically meets only few of the above requirements. So far my best tutorial is from Chapter 3-2 in the Oreilly book by John Levine - it has AST; all C though, meets only Re_1 above. I welcome recommendations for nice examples / tutorials, real life open source projects. For example I saw MySql .yy file - looks well written, but too big/complex for beginner like me.</p>

1. COYou mean coded in C++? Or you want to parse C++?

2. COI want my code that interacts with flex/bison to be C++. In particular the AST (Abstract Syntax Tree). The mentioned example depends on c type-leniency. Plus I want to use STL, etc. As far as what I am trying to parse: a simple syntax similar to regular expressions.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
