A parser for the cool language. The program outputs what would be a AST for a given cool code. Further information about this project can be found in tp3-ingles.pdf and tp4-ingles.pdf. Documentation about the Cool language is available here.
To build from source, run:
$ cd src/
$ ./gen
this will generate the file system specific files into your src folder, including the executable myparser. After running the command, your src folder should look like this:
Makefile -> [cool dir]/src/parser/Makefile
README
cool.y -> bison file
bad.cl -> syntax error examples
good.cl -> program examples
cool-tree.handcode.h
cool-tree.cc -> [cool dir]/src/parser/cool-tree.cc
cool-tree.aps -> [cool dir]/src/parser/cool-tree.aps
dumptype.cc -> [cool dir]/src/parser/dumptype.cc
handle_flags.c -> [cool dir]/src/parser/handle_flags.cc
parser-phase.cc -> [cool dir]/src/parser/parser-phase.cc
stringtab.cc -> [cool dir]/src/parser/stringtab.cc
tokens-lex.cc -> [cool dir]/src/parser/tokens-lex.cc
tree.cc -> [cool dir]/src/parser/tree.cc
utilities.cc -> [cool dir]/src/parser/utilities.cc

Run make on the src folder to rebuild myparser after making any changes to the source code.
In order to build the project, you will need to have the following packages installed in your environment:
as well as some x86 packages that can be installed in debian systems by running:
$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
To parse a Cool program, simply run:
$ ./src/myparser program.cl
which will output the AST on the stdout.
To run the parser over a set of test inputs execute the script located at src/run-test. A set of default tests is available at src/examples/. Each file tries to cover one part of cool's grammar as defined in cool.y. Nevertheless, you can run the parser over any set of .cl files by running:
$ ./src/run-test path/to/example/folder/
Consider the input:
class A {
name: String <- "Jhon";
};
class BB__ inherits A {
foo(): String {
{
"Helo";
"World!";
}
};
};
it will produce the following output:
#1
_program

_class

"good.cl"
(
#2
_attr

_assign
