mORMot Static Compilation Notice

The following modifications have been made by Synopse to the original source code:

• started not from original Bellard's repository, but https://github.com/c-smile/quickjspp fork;
• merged back the official https://github.com/bellard/quickjs updates, even when the c-smile fork is outdated;
• enabled BIGNUM, JSX and debugger extensions by default;
• forced JS_STRICT_NAN_BOXING on all targets, for a single 64-bit contained JSValue definition;
• quickjs-libc is not linked to enhance cross-compilation and to be reimplemented in native pascal instead of native c - js_module_set_import_meta/js_std_eval_binary were moved to the main quickjs.c file;
• regrouped all source code into a single quickjs2.c amalgamation source file (to fix cyclic static definitions) and facilitate Delphi static linking;
• assert() and abort() redirect to less painful pascal Exceptions (how want a SIG_ABRT to kill your service?);
• pas_malloc/free redirection to the pascal MM for best performance and less memory fragmentation;
• simple per-target compilation scripts (no complex make files) dedicated to FPC and Delphi static linking using the FpcUpDeluxe cross-compilers.

With some proper tricks, we were able to compile QuickJS using mingw/gcc for FPC (the easy part), and also for Delphi Win32/Win64 - even if they don't support their format. \o/

This source code is included as reference. Please don't try to compile the static files by yourself, but download them from the latest https://github.com/synopse/mORMot2/releases or https://synopse.info/files/mormot2static.7z

QuickJS Javascript Engine

Authors: Fabrice Bellard and Charlie Gordon

Ported from https://bellard.org/quickjs/ and its official GitHub mirror https://github.com/bellard/quickjs

By Andrew Fedoniouk (a.k.a. c-smile)

This version is

• Microsoft Visual C++ compatible/compileable
• Is used in Sciter.JS
• It contains extras:
  • JSX - built-in facebook::JSX support with Sciter specific extras.
  • Built-in Persistence - you can think of it as local MongoDB (NoSQL) DB embedded into the language. Pretty small, adds just 70kb into binary.

The main documentation is in doc/quickjs.pdf or doc/quickjs.html.

Build using Microsoft Visual Studio (2017 or 2019)

Prerequisite: premake5 - download and install it.

Then go to /win folder and run premake-vs2017.bat or premake-vs2019.bat .

It will generate .build/vs2017/quickjs-msvc.sln and open it in Microsoft Visual Studio.

Press F5 to compile it and run qjs - interactive JS command line application.

Premake5 and build on other platforms/compilers/ide

Supported premake options:

• --jsx - include JSX support;
• --storage - include Persistent Storage support;

Supported targets (these are built into Premake itself):

• vs2017 - MS Visual Studio 2017
• vs2019 - MS Visual Studio 2019
• gmake2 - gmake files
• etc...

Few examples of other possible configurations:

premake5 vs2019 --jsx --storage
premake5 codeblocks --cc=gcc --jsx --storage
premake5 gmake2 --cc=gcc --jsx --storage
premake5 gmake2 --cc=clang --jsx --storage
premake5 gmake2 --cc=clang --jsx --storage
premake5 xcode4 --jsx --storage
