An implementation of the Frank programming language described in the POPL 2017 paper, ``Do be do be do'' by Sam Lindley, Conor McBride, and Craig McLaughlin. See the (revised) paper at: https://arxiv.org/abs/1611.09259
Further enhancements are described by Lukas Convent in his MSc thesis of 2017: http://lukas.convnet.de/proj/master/index.html
The easiest way to install frank
is to use stack (external
website,
github):
stack setup
The above command will setup a sandboxed GHC system with the required dependencies for the project.
stack install
The above command builds the project locally (./.stack-work/...
) and then
installs the executable frank
to the local bin path (executing stack path --local-bin
will display the path).
To run a frank
program foo.fk
:
frank foo.fk
By default the entry point is main
. Alternative entry points can be
selected using the --entry-point
option.
Some example frank
programs can be found in examples
. They should
each be invoked with --entry-point tXX
for an appropriate number
XX
. See the source code for details.
To specify a search path for source files use -I
or --include=INC
.
Optionally a shonky file can be
output with the --output-shonky
option.
Further debug options are
--debug-output
: Enable all debugging facilities--debug-verbose
: Enable verbose variable names etc. on output--debug-tc
: Enable output of type-checking logsOnly top-level mutually recursive computation bindings are supported
Coverage checking is not implemented
