BreakVoid/Mental

a compiler for Mx* language

Mental

This is a repository of my course "Principles of Compilers". It is a compiler of Mx* language.

Introduction of Language

Mx* language is a Java-like programming language. But the class in Mx* language is similar to the struct in C.

Built in Functions

void print(string str)

print str to stdout.

void println(string str)

print str and a newline('\n') to stdout

string getString()

get a line of characters from stdin and return a string object contained the characters.

int getInt()

get a line of characters from stdin and return a first decimal integer.

string toString(int)

convert a integer to a string object.

string.length()

return a integer which is the length of a string.

string.substring(int left, int right)

return a new string object which contain the characters subscripting from $left$ to $right$.

string.ord(int pos)

return the ASCII value of the character with subscripting $pos$. (0-base)

string.parseInt()

return the first integer in the beginning of the string. The prefix of the string should be a integer.

array.size()

return the size of the array.

Introduction to Mental

Input

A source file of Mx* language. The source file should be redirect to stdin.

Output

SPIM assemble code in stdout.
