ocaml / stdlib-shims

Shim to substitute `Pervasives` with `Stdlib` before 4.08.

stdlib-shims

Compiling against this library allows to replace your uses of Pervasives with Stdlib before 4.08. For example you can use Stdlib.compare instead of Pervasives.compare. It does not however provide the new functions and modules that are being added in Stdlib module.

Installation

To install the project via opam, the standard package manager for OCaml, type:

opam install stdlib-shims

usage?

how is this used?
merely adding this to opam dependency list still gets me unknown module Stdlib error

Missing 0.2.0 in opam-repository

The version 0.2.0 is not currently in opam-repository. However it is going to be required for the OCaml 4.12 support. Was there something stopping it to be fully released?

Error: Rule failed to generate the following targets src/stdlib_shims.a

I am trying to build stdlib-shims for OCaml 4.12.0 (https://github.com/ocaml/ocaml/archive/trunk.tar.gz) with dune.2.6.0, and I get the following error:

File "_build/.dune/default/src/dune", line 2, characters 0-75:
2 | (library
3 |  (wrapped false)
4 |  (name stdlib_shims)
5 |  (public_name stdlib-shims))
Error: Rule failed to generate the following targets:
- src/stdlib_shims.a

What could be the reason?

Compilation fails with 4.10.0+msvc64c

As explained in this comment, the fix for msvc has to be updated with each new compiler release.

Is it related to stdcompat?

Hello,

Sorry for the maybe silly question, but what is the difference with stdcompat?
The README is super terse, so...

https://github.com/thierry-martinez/stdcompat

Not related, does stdlib-shims have non tail recursive code?

Thanks,
F.

Why is there no Int module?

Is there a reason why there is no Int module in stdlib-shims? It is not clear to me from #9 (comment) if it should be part of the library or not.

I'd be happy to add the module if you are okay with it.

opam switches 4.12.0 and up fail to produce `stdlib_shims.a`

On my installation it looks like versions 4.12 and up are failing to produce stdlib-shims/stdlib_shims.a. They do produce stdlib-shims/stdlib_shims.cmxa. To reproduce install the switch then install ounit2. Is this a bug?

Looks like ocamlopt -a tries to create an empty library and so there is no .lib file? With OCaml 4.02.3 Win32 I have no such problem.
