PAS2PHP

PAS2PHP will translate a large subset of Object Pascal to PHP, allowing you to write web applications using Lazarus/FreePascal, and then run the application on a standard HTML/PHP server. Over the last week, a lot of work has gone into PAS2PHP. Most of the major issues are resolved. There are still a number of incompatibilities which are either not fixable, or have simple workarounds. As of v0.5, you should be able to write entire PHP applications in Pascal. The key to coding for PAS2PHP is to understand the limitations of PHP. Read the example code provided, and always check the outputed PHP code to understand how this works. As a guide to what PAS2PHP can achieve... my web site is written in Pascal, and then converted to PHP. (The code is in the source package). PAS2PHP uses the Pascal Parse Tree Classes (PasTree) which comes with FreePascal, and therefore the parsing limits are defined by this library.

MathParser

An expression parser and a virtual machine. A formula is compiled to a flat byte array and evaluated by a linear pass over it, with no allocation on the path of an ordinary formula. On x86-64 an optional accelerator compiles that bytecode to machine code and hands anything it declines back to the interpreter, so an answer is never fast but wrong. Results are cached by shape: once 2 + 3 has been compiled, 5 + 7 reuses the same script and only writes the numbers into a copy. 163 functions to call and 249 names in the table, your own functions and variables bound by address, symbolic differentiation. The Lazarus parser packages require FCL and define NOFORMS and NOGRAPHICS, so they install without LCL. WebAssembly uses a separate console configuration. Two units ask for more at their defaults, Thread through Application.HandleException and BlobManager through TGraphic; drop the defines and add the LCL to the package if you want them.
