Frink is an implementation of the Forth programming language, with the
Atto virtual machine as its compile target. Frink reads .fk, such as
test/ and compiles them down to Atto bytecode.
I plan to allow the compile/run process to be done directly from Frink, without having to run Atto, or generate bytecode. This will be added eventually, but right now, it can only compile to bytecode.
Frink depends on Atto to build. After cloning this repository, running
make will clone the Atto repository and build it
make distclean all will remove the old Atto
lib, and download and build fresh version of the repository.
After building frink, compile frink files with
This will generate
out.ato, which can be run by the Atto virtual
Frink is an implementation of Forth, and as such is a stack
based language. There are a bunch of standard Forth-ish words, like
In Frink you can define constants, which are immutable values,
probably used frequently in code. They basically act like #define does
in C. They are set with
constant <name> <value> and can be used
throughout the code instead of using the actual value. Value can be
either a string or a number.
Here's an example of how to use them:
constant number 42
Vars are sort-of kind-of like pointers in C (sort of). They cannot be
accessed directly, but must be set and read with the special words
value. A var is declared by
Here's an example:
1 x set ( sets the var)
x .cr ( doesn't print 1!)
( prints something like `Var@0xbf8cdb20')
x value .cr ( prints 1)
