How to build Flow

Asked 2018-Feb-14 at 21:35

I'm trying to build flow so that I can make modifications to their code and build my own version to use and test. But when I'm trying to build it, it dies. The following steps were used:

Install OCaml (followed steps from https://ocaml.org/docs/install.html)

The pertinent error info appears to be ocamlfind: Package 'wtf8' not found.

Have you inited opam? If not you need to run opam init --comp 4.03.0 and restart your shell before running the other opam commands. (For more detail, see https://opam.ocaml.org/doc/Usage.html).

If you have, run opam list and see if wtf8 is in the list of installed packages. If it is not in the list, try running opam install wtf8. If it is in the list, try following the solutions to this same issue here ocamlfind cannot see installed package.

QUESTION

The set of WTF-8 strings that are ill-formed UTF-8 as 16-bit slices

Asked 2017-Dec-11 at 10:50

I'm trying to define the set of 16-bit slices (Rust: &[u16]) that are valid WTF-8 (when re-encoded), but not valid UTF-8 (when re-encoded), so that I can randomly generate such a slice. This in an effort to generate all the possible std::ffi::OsStrings on Windows machines that do not parse into a String.

The conversion &[u16] -> OsString is done via std::os::windows::ffi::OsStringExt::from_wide. This redirects into libstd/sys_common/wtf8.rs which defines the operation as:

It isn't completely clear to me whether you want to generate a string in WTF-16 \ UTF-16 or WTF-8 \ UTF-8. I think generating a WTF-16 string that isn't valid UTF-16 is probably easier, so here it goes:

You need to make sure at least one (16-bit) "character" is a surrogate that is not part of a surrogate pair. (This example might also generate NUL characters in the string.)

You can use enable_if to constrain your constructor not to take more than 22 characters:
