WebScripter IDE for Mac

From The Alchemist Guild:

WebScripter is an integrated development environment (IDE) for programming in several popular web scripting languages such as: PERL, PHP, CSS, HTML/XML, JavaScript and Ruby.

WebScripter offers powerful features to help improve productivity and manageability in all areas of the trade, including: text editing, previewing web pages, testing scripts, managing projects, navigating code and FTP integration. Designed with the principal in mind: "everything you need, needs to be where you need it" WebScripter will help give you a place to work where you're productive and comfortable because you're surrounded by the tools you need to get the job done.

Text editing is improved over standard editors by robust syntax coloring, scriptable macros that can run UNIX commands, drag and drop snippets and other shortcuts. Web pages can be previewed from within the application, in external browsers or in real-time while typing. Scripts such as PERL, PHP and Ruby can be executed and previewed, just like from the command like while helping you handle errors that may occur. Code is made easier to navigate by the powerful syntax parser which collects information in your files (functions, variables, classes, etc...) and then lets you navigate them by that data. For testing scripts on the web server, WebScripter features a built-in FTP client that lets you edit files directly on the server, just like a file on your hard disk.
