F*: An ML-like language aimed at program verification
This package will install F* language with compatable version of z3.
It is recommended that you remove your z3 package and then install F*
More information on F* can be found at www.fstar-lang.org
The F* tutorial provides a first taste of verified programming in
F*, explaining things by example.
The F* wiki contains additional, usually more in-depth, technical
documentation on F*.
Editing F* code
You can edit F* code using your favourite text editor, but Emacs,
Atom, and Vim have extensions that add special support for F*,
including syntax highlighting and interactive development. More
details on editor support on the F* wiki .
Executing F* code
By default F* only verifies the input code, it does not compile or execute it.
To execute F* code one needs to translate it to either OCaml or F#, using
F*'s code extraction facility---this is invoked using the command line
--codegen OCaml or
--codegen FSharp. More details on
executing F* code on the F* wiki .
Community mailing list
The fstar-club mailing list is dedicated to F* users. Here is where
all F* announcements are made to the general public (e.g. for
releases, new papers, etc) and where users can ask questions, ask for
help, discuss, provide feedback, announce jobs requiring at least 10
years of F* experience, etc.
Users can also ask questions on the
#fstar Slack channel at
< http://fpchat.com/ >
Please report issues using the F* issue tracker on GitHub.
Before filing please use search to make sure the issue doesn't already exist.
We don't maintain old releases, so if possible please use the
online F* editor or directly the GitHub sources to check
that your problem still exists on the
The F* for the masses blog is also expected to become an important
source of information and news on the F* project.
