XML to DDL is a set of Python programs that converts an XML representation of a database into a set of SQL or DDL (Data Definition Language) commands. In addition, it can examine the difference between two XML files and output a sequence of SQL statements (normally ALTER statements) to bring one database up-to-date with the XML schema. You can also download the XML schema directly from the database. Finally, there's a tool to convert your schema into HTML for documentation purposes. XML to DDL currently supports the most recent versions of PostgreSQL, MySQL, Oracle, and Firebird databases.
wxOptParse is a Python program that brings up a graphical representation of the command line options of a Python program, if it happens to use the standard optparse module. What this means is that if if you have a program that uses optparse you can optionally click on checkboxes, edit boxes, combo boxes, etc. instead of using the command line.
Clipboard Modifier is a flexible system to modify the text in a clipboard in a variety of ways. It can copy a spreadsheet and change the clipboard so that it can be pasted into a wiki, with vertical bars (|) instead of tabs. It can modify multi-line clipboard text so that it can be pasted into Java or Python as strings. An URL in the clipboard pointing to Amazon can be modified so that it has your Associate ID in it. It can pipe the clipboard to a shell command and retrieve the output from it. A clibpboard can be forced to text, removing things like formatting. A complicated URL can be converted into its Python equivalent, using urlencode.
