XML to JSON translator project

Lex / Yacc + Python Project which translate XML to JSON, draws objects on screen using Turtle package, and contains a basic script-like behavior, which can create variables, make sums, can use if-statements, and print variables.

Requirements (Linux):

• Lex / Yacc
• Python 3 + Turtle Package

Additional requirements (Windows Subsystem for Linux):

• install Xming: https://sourceforge.net/projects/xming/
• run XLaunch with default config (Next=>Next=>Next=>Finish)
• run this command in bash terminal export DISPLAY:=0

How to run:

make all (handles lex, yacc, and creates exe.)
./TRANSLATOR < *INPUT_FILE*

JSON Output can be seen in translator_output.txt

Available input files:

• translator_input_draw
• translator_input_script
• translator_input_test

Accepted structures:

• Object with value:
  <objectName> value </objectName>
• Object with subobjects:

    <objectName>  
        <subobjectName1>...</suobjectName1>  
        <subobjectName2>...</suobjectName2>  
    </objectName>
    
    <objectName subobjectName1="value" subobjectName2="value" ...> </objectName>

Basic script functions:

• Variable declaration:

    <variable>
        <variableName>
            value
        </variableName>
    </variable>

• If statement:

    <if variableName="variableValue">
        <otherTag1> ... </otherTag1>
        <otherTag2> ... </otherTag2>
    </if>

if variableName has the value equal with variableValue then the otherTags will be executed

• Print function:

    <variable> <a> 10 </a> </variable>
    <print> a </print>

• Sum function:

    <variable> <a> 10 </a> </variable>
    <variable> <b> 11 </b> </variable>    
    <variable> <c> 12 </c> </variable>    
    <sum>
        <d>
            <it>a</it>
            <it>b</it>
            <it>c</it>
        </d>
    </sum>

creates a new variable d, and stores the sum of the variables a, b, c
