miniJavaToTikz

miniJavaToTikz is a program converting programs in miniJava-syntax to control flow diagrams represented by tikzpictures.

Usage

Compile miniJavaToTikz.hs with ghc, and then run the program with

miniJavaToTikz <filename>

<filename> is a string pointing to a miniJava-file, e.g. example.miniJava. The output will be saved into <filename>.tex, e.g. example.miniJava.tex.

Example

The file example.miniJava contains an example for a miniJava-program. The output looks as follows:

Some manual adjustments might be required afterwards.

miniJava-Syntax

miniJava programs accepted are roughly of the following structure:

<Statement> ::=
        <Read>
        | <Write>
        | <Assign>
        | <If>
        | <IfElse>
        | <While>
        | <Statement> <Statement>
<Read> ::= <VarName> = read();
<Write> ::= write(<VarName>);
<Assign> ::= <VarName> = <Expression>;
<If> ::= if (<Condition>) { <Statement> };
<IfElse> ::= if (<Condition>) { <Statement> } else { <Statement> };
<While> ::= while (<Condition>) { <Statement> };

<Condition>, <Expression> and <VarName> are currently just strings not containing {, }, ;.
