Edit is a scripting language I've developed with syntax similar to a combination of Java, Lua, and Python. Functionality includes call to functions with return values and the ability to evaluate complex expressions. I created it for many reasons including, practice coding, learn about the challenges that developing languages face, extend the functionality to be able to one day use it in an application, and to practice some concepts I've learned in class such as using trees, stacks, and maps.
Use EditDemo.java to run
Making the language objective is the next step I want to take. It shouldn't be too hard considering that I learned how to keep separate functions on different stacks with their own maps of variables and values. The way I plan to achieve this is to parse all the necessary files before the program executes and storing it in a map, and when a new Object is created, a new instance of that compilation would be added to the current program stack. This works great because each pared file can store its own values for variables and return values when it's functions are called.
This is currently the extent of it's functionality:
#This will be ignored
print "this tests the evaluator"
function ending(x) do
x = plusOne(x)
while x > 0 do
print "This will print at the end x + 1 times"
x = x - 1
end
end
function plusOne(x) do
while true do
return x + 1
print "This is unreachable code"
end
if not false then
print "This is also unreachable"
end
end
print #This will be ignored
x = 6
if x < 4 then
print "This won't print"
else if x == 5 then
print "This won't print either"
else
print "This will print" #This will be ignored
end
print true and false
print true or false
print true xand false
print true xor false
print not true
print
#This will be ignored
print "This is a" , "comma."
print "This is a" ; "semi-colon."
print
input "Pick a val for x: ", x
print
print 2 + x * -2
print 2 - x / 2
print x ^ 3 % 7
print "hello" + " " + "world"
print
print 2 > x or false
print 2 < x or false
print 2 <= x and true
print 2 >= x and true
print 2 == x and true
print
if x > 0 then
for i = 0, i < x, i + 1 do
print i
end
else
while x < 0 do
print x
x = x + 1
end
end
print
ending(x)
#This will be ignored
This will print
false
true

This is a comma.
This is a semi-colon.
