Quack Parser with AST

How to Run

Download the code

First make sure that you have Golang installed on your system and that you have your $GOPATH set. It is normally defaulted to $HOME/go

Go is really particular when it comes to import references having absolute paths. That's why when you: git clone https://github.com/Lebonesco/quack_parser.git make sure that it is in the file path: $GOPATH/src/github.com/Lebonesco/

At this point, everything can be run from the Makefile

Build, Test, Run Program

make file=test.txt

Install Dependencies

make deps

Build Program

make build

Run Unit Tests

make test

Run Program

make run file=text.txt

Clean Directory

make clean

How to Run Manually

Install the Parser Tool (gocc)

git clone https://github.com/goccmack/gocc.git

It will download to $GOPATH/go/bin Make sure that this directory is in your Path

Generate the Lexer and Parser

gocc quack.bnf

Run Program

To run program with test file/file path: go run main.go text.txt

Run Unit Tests

To run unit tests:

$ go test -v
=== RUN   TestFiles
Testing file 1/77 - Another_plus_good.qk
Testing file 2/77 - Another_plus_types_bad.qk
...
Testing file 77/77 - while_init.qk
--- PASS: TestFiles (0.03s)
--- PASS: TestClassVariableCall (0.00s)
=== RUN   TestMethodCall
--- PASS: TestMethodCall (0.00s)
PASS
ok      github.com/Lebonesco/quack_parser       0.371s

Missing Functionality

lacks code generation for typecase statements
unable to generate correct multiline, triple quote strings
havent fully completed code generation for prefix values
