tryc's Introduction

tryC - a small interpreter written by C

tryC is a very simple interpreter made by hand in C language, about 570 lines:

Use recursive descent method for grammatical analysis, do not explicitly build a grammar tree, generate intermediate code or target code; interpret and execute at the same time as grammatical analysis.

The try language implemented by tryC:

Dynamic types, supported data types: double-precision floating-point numbers, character types, strings, arrays of floating-point numbers;
Support the definition of functions and variables, recursive call of functions, nested scope;

tryC是一个用c语言手搓的非常简单的解释器，大约570行：

采用递归下降法进行语法分析，不显式构建语法树，不生成中间代码或目标代码，在语法分析的同时进行解释执行；

tryC实现的try语言：

动态类型，支持的数据类型：双精度浮点数、字符型、字符串、浮点数数组
支持函数和变量的定义、函数的递归调用、嵌套作用域

files：

source：tryC.c

example：test.try

build and run：

build:

gcc -o tryc tryC.c

usage:

tryc [-d] filename

tryc's Issues

处理逻辑And和OR的短路代码有一些问题

当BoolAnd第一个参数为false时直接返回导致 && 后的表达式没有被处理到
match(')')的时候会报错退出
