Teeny

A transpiler to convert BASIC like code to C

Variables (For now only ints and floats are supported)

LET a = 4
LET b = 8.278
LET c = a + b

Operators (Arithmetic and comparison)

LET a = 45
LET b = a * a
LET c = b - a
LET d = c / a

Conditionals

IF a > 5 THEN
    PRINTLN "A is greater than 5"
ENDIF

Looping

LET n = 5
LET s = 0
WHILE n > 0 REPEAT
    LET s = s + n
    LET n = n - 1
ENDWHILE

Built-ins

PRINT "Hi!!"
PRINTLN "Print but with a newline"
PRINTLN 3 + 5

Output

Hi!!Print but with a newline
8

INPUT - takes a number input

INPUT n
WHILE n > 5 REPEAT
    PRINT n
    PRINT " "
    LET n = n - 1
ENDWHILE
PRINTLN ""

Calling C code

LET a = 4
LET b = 5
`
    b = a * a;
    printf("Changed b to %f\n", b);
`
PRINTLN b

Comments

# This is a comment
PRINTLN "Hello!" # This will be ignored
