# Friday opam hacking

## Useful information
Opam health check filter: http://check.ocamllabs.io/?comp=4.14&comp=5.0&available=4.14&available=5.0&show-only=bad&show-diff-only=true&sort-by-revdeps=true&maintainers=&logsearch=&logsearch_comp=4.14

When fixing a package and after an upstream PR has been open, adding the package(s) to https://github.com/kit-ty-kate/opam-alpha-repository is very much appreciated.
Just call the `./add-pkg.sh` script with the package(s) you want to add, modify their `src` field and remove the `checksum` and the PR should be good to go.

## Packages under analysis

#### dbuenzli

* `brr`, `js_of_ocaml` has been updated for 5.0.0 but `brr` needs a few tweaks and a release to support the latest `jsoo` version. Will do.

In fact that may not be needed, see [this PR](https://github.com/ocaml/opam-repository/pull/22600) on the opam repository. New release still coming though.

#### octachron
* `gsl-ocaml`: fix examples
* `oasis` requires ocamlify: later
* `ocamlify` use oasis generated files: later
* `pgocaml`: missing camlp-streams dependency
* `camlimages`: deprecated functions, dependency on lablgtk

#### dangdennis

* ~~`usb.1.3.1`~~ - Unable to setup local package from [source](https://github.com/letoh/ocaml-usb) because it uses oasis.
* [`rlp`](https://opam.ocaml.org/packages/rlp/) - wip. depends on rope. uses oasis. would also require strong opinionated choices
* [`rope`](https://opam.ocaml.org/packages/rope/) - PR opened to alpha opam repo

#### mseri

* ~~[text](https://github.com/vbmithr/ocaml-text)~~ needs porting from oasis, I cannot do it without some strong opinionated choices and in reasonable time
* [gettext](https://github.com/gildor478/ocaml-gettext): upstream PR ~~[#25](https://github.com/gildor478/ocaml-gettext/pull/25)~~ [#24](https://github.com/gildor478/ocaml-gettext/pull/25) and [#26](https://github.com/gildor478/ocaml-gettext/pull/25)
