About The Project

In this project we implement two phase of decaf compiler .

First phase is Lexical analysis and It takes modified source code from language preprocessors that are written in the form of sentences.

The lexical analyzer breaks these syntaxes into a series of tokens, by removing any whitespace or comments in the source code.

If the lexical analyzer finds a token invalid, it generates an error.

Also In the first phase we have Preprocessor which handle DEFINE macro before breaks syntaxes into a series of tokens.

In the second phase we need to Parsing code .

Parsing or (syntax analysis) is the process of analyzing text containing a sequence of tokens to determine its grammatical structure with respect to grammar.

In this project we can give the decaf code as an input and in the last if syntax of code was true we get series of tokens else we get syntax error.

Built With

This section should list any major frameworks/libraries used to bootstrap your project. Leave any add-ons/plugins for the acknowledgements section. Here are a few examples.

Getting Started

This is an example of how you may give instructions on setting up your project locally. follow these simple example steps.

JAR_Files

we have two JAR files in src/compiler directory , one of them is jflex-full-1.8.2.jar and another is java-cup-11b.jar .

compile jflex file (convert to java file)

First in Terminal you should go to src/compiler directory
you should use command like this for go to directory
```
 cd src/compiler
```

then for compile you should use this command

java -jar jflex-full-1.8.2.jar Scanner_Jflex.flex

compile CUP file

First in Terminal you should go to src/compiler directory
you should use command like this for go to directory
```
 cd src/compiler
```
then for compile you should use this command
```
java -jar java-cup-11b.jar Parser.cup
```

RUN_TESTS

For run and use this project you should create new text file and write your decaf code in that. then you should copy that text file's address .

open the project and go to Testing.java in src/compiler directory

then in line 9 paste that copied address in the file methode argument

now run Testing.java .

you can see the result in your IDE Run console.
