Standart of file

File has text format, consists of printed prefix tree and list of variables. My tree file is named similar to source and has extension .tree

Prefix tree

• The complete bracket sequence. Node (value left_subtree right_subtree)
• No subtree: _

Value of node

<type of data> <data>

Type of data in {1,2,3}

• 1: Operator, data - code in table for each operator in language
• 2: Number, data - number, int/double in format 1.0
• 3: Variable, data - index in table of variables

Table of operators

Name/Priority	Code	Type	Description	Equavalent in C
FUNC_DEF	10	Binary	Operator of function definition(body). Left node - FUNC_DEF_HELP Left Node - type of ret(var/void) Right Node - var(name of function) Right node - FUNC_DEF_HELP Left Node - subtree of vars-arguments and DIVIDER_ARG Right Node - instructions	int summ(int a, int b){...}

List of variables

After tree its place for list of variables

<index(begin with 0)> <name_of_varible>

Code:

var x;                   
var y = x+1;
if (1) {
    print(x);
}

Tree:

(1 21 (1 21 (1 21 (1 100  _ (3 0  _  _ )) _ )(1 100  _ (1 20 (3 1  _  _ )(1 40 (3 0  _  _ )(2 1  _  _ )))))(1 102 (2 1  _  _ )(1 21 (1 12 (3 2  _  _ )(3 0  _  _ )) _ )))
0	x
1	y
2	print
