I have just finished the first version of bytecode-interpreter.Īfter this test, i will release version 4.0!
#Flightgear v3.0 update#
Bytecode Virtual Machine version 4.0 vm (last update 7) It will be harder for me to make the bytecode vm become more efficient. version 5.0 ast (last update )ĪST interpreter leaves me too much things to do. Because it took me a long time to think and write. I decide to save the ast interpreter after releasing v4.0. Now you can add your own functions as builtin-functions in this interpreter! The ast is refactored and is now easier to read and maintain.Īst-interpreter uses new techniques so it can run codes more efficiently. version 2.0 ast (last update 1)Ī completed ast-interpreter with unfinished lib functions. The ast has been completed in this version. Abstract Syntax Tree version 1.2 ast (last update 1) In version 0.17(5) 0.18(8) 0.19()i was playing the parser happily and after that i wrote version 1.0. Use these commands to get version of interpreter:įirst fully functional version of nasal_parser.īefore version 1.0,i tried many times to create a correct parser.įinally i learned LL(1) and LL(k) and wrote a parser for math formulas in version 0.16(last update 4). Input this command to run scripts directly:
#Flightgear v3.0 how to#
Or using makefile, mingw32-make is Windows(MinGW-w64) platform's make:įirst we should learn how to write and run a program using this language, std=c++11 -O3 main.cpp -o nasal -fno-exceptions -ldl Or use g++/clang++ on linux/macOS/Unix platform. G++ -std=c++11 -O3 main.cpp -o nasal.exe -fno-exceptions -static (otherwise don't blame me for not reminding YOU 👿 ) There are some tips to fix the release manually. How to Compileīetter choose the latest update of the interpreter.ĭownload the source and build it! It's quite easy to build this interpreter.ĬAUTION: If want to use the release zip/tar.gz file to build the interpreter, please read the Release Notes below to make sure this release file has no fatal bugs. This interpreter a useful tool in your own projects (such as a script in a game just as Flightgear does). Interesting programs and run them without the lib of Flightgear.
We found it much easier to check syntax and runtimeĮrrors before copying nasal-codes in nasal-console in Flightgear to test.Īlso, you could use this language to write some So i tried to write a new interpreter to help them checking syntax error and even, runtime error.īytecode virtual machine(there was an ast-interpreter,īut deleted after v4.0) to help checking errors. Members in FGPRC told me that it is hard to debug with nasal-console in Flightgear, Use this project to learn or create more interesting things
#Flightgear v3.0 code#
Without reusing the code in Andy Ross's nasal interpreter.īut we really appreciate that Andy created this amazing programming language and his interpreter project. The interpreter is totally rewritten by ValKmjolnir using C++( -std=c++11) Is an ECMAscript-like programming language that used in FlightGear.
