My own programming language. This is a project I had to do for a class during my engineering studies. So it's completely in spanish. It's basically a proof of concept showing my own language which was designed to avoid all kind of special language keywords

#The entire language is made out of symbols, except for variable declarations.

It has an internal and custom designed state machine as a parser because we were not allowed to use flex. To compile it you have to run bison on the .y file, then g++ on the output, and then use the compiler to compile "prueba.txt". The output from running the final compiler is an asm file with GNU Assembled compatible code. You can run "crear_compilador.sh" that does it all for you.

So let's get to the interesting part. The language:

##Valid Comments

/*
comment 1
*/
/*
comment 2
/*
comment 3
*/
*/

##Variable definitions (the only place where english keywords are allowed)

real 3.14@pi
int var1
int var2
int 0@var3
int var4
string 'hello '@string1
string 'world'@string2
string string1+string2@string3

##Variable assignation

0@var4

##Print to console

print('0@var4:')
print(var4)
print('~(var4)')
print(~(var4))

##Special operations

2+@var1
2-@var1
2*@var1
2/@var1

##IF condition

pi>3.13?
print('pi is greater than 3.13')
:
print('pi is not greater than 3.13')
;
/*
of course you will never reach the "else" code. it's just an example. stop complaining
*/

##WHILE loop

/*
while var3<8 keep increasing var3 by one
*/
{var3<8}
1+@var3
;

##FOR loop

/*
there is no difference between while and for. you just add new code before the condition like this:
{code1:code2:code3:condition}
code
;
Here is a working example:
*/
{2+@var4:var4<8}
1+@var3
print(var3)
print(var4)
;

Warnings: Assembly code was writen on a single day, and it had to work on first try, so from an academic and professional point of view, one could say that it's very crappy- The BNF is not considering some cases for the IF conditions. This is just a "working" compiler used as proof of concept. It was not meant to be complete, full featured, or bug free. The entire program AND the language itself are LGPL licensed.
