# Hkgr [![Hackage](https://img.shields.io/hackage/v/hkgr.svg)](https://hackage.haskell.org/package/hkgr) [![GPL-3 license](https://img.shields.io/badge/license-GPL--3-blue.svg)](LICENSE) [![GitHub CI](https://github.com/juhp/hkgr/workflows/build/badge.svg)](https://github.com/juhp/hkgr/actions) `hkgr` (pronounced "hackager") is a tool for making releases of Haskell packages on Hackage. It uses a cautious stepped iterative approach to releases. ## Example usage Here is an example of doing a release of hkgr itself. After committing the latest changes for the release, create a tag and tarball: ```shellsession $ hkgr tagdist v0.4 No errors or warnings could be found in the package. Running hlint src/Main.hs:(407,9)-(408,55): Warning: Eta reduce Found: replaceHolder lbl val file = sed ["s/@" ++ lbl ++ "@/" ++ val ++ "/"] file Perhaps: replaceHolder lbl val = sed ["s/@" ++ lbl ++ "@/" ++ val ++ "/"] [] ["src/Main.hs","data/template.cabal.tmpl","README.md","CHANGELOG.md","LICENSE","hkgr.cabal"] [(NoExec,"CHANGELOG.md"),(NoExec,"LICENSE"),(NoExec,"README.md"),(NoExec,"data/template.cabal.tmpl"),(NoExec,"hkgr.cabal"),(NoExec,"src/Main.hs")] Wrote tarball sdist to /home/petersen/github/hkgr/.hkgr/hkgr-0.4.tar.gz ``` After fixing up, retag a new tarball with `--force` and upload candidate, in one go: ```shellsession $ hkgr upload -f Updated tag 'v0.4' (was f6d72ba) No errors or warnings could be found in the package. Running hlint [] ["src/Main.hs","data/template.cabal.tmpl","README.md","CHANGELOG.md","LICENSE","hkgr.cabal"] [(NoExec,"CHANGELOG.md"),(NoExec,"LICENSE"),(NoExec,"README.md"),(NoExec,"data/template.cabal.tmpl"),(NoExec,"hkgr.cabal"),(NoExec,"src/Main.hs")] Wrote tarball sdist to /home/petersen/github/hkgr/.hkgr/hkgr-0.4.tar.gz hackage.haskell.org password: Uploaded to https://hackage.haskell.org/package/hkgr-0.4/candidate ``` Alternatively if you had manually tagged the release with `v0.4` you can use `hkgr tagdist --existing-tag` to create a dist tarball. One can continue to `tagdist -f` and/or `upload -f` until everything looks good and CI passed etc. Then it is time to push the final tag and publish the release: ```shellsession $ hkgr publish git pushing... done Total 0 (delta 0), reused 0 (delta 0), pack-reused 0 To github.com:juhp/hkgr.git * [new tag] v0.4 -> v0.4 hackage.haskell.org password: Published at https://hackage.haskell.org/package/hkgr-0.4 ``` ## Help `$ hkgr --version` ``` 0.4.4 ``` `$ hkgr --help` ``` Hackage Release tool Usage: hkgr [--version] COMMAND 'Hackager' is a package release tool for easy Hackage workflow Available options: -h,--help Show this help text --version Show version Available commands: new setup a new project tagdist 'git tag' version and 'cabal sdist' tarball upload 'cabal upload' candidate tarball to Hackage publish Publish to Hackage ('cabal upload --publish') upload-haddock Upload candidate documentation to Hackage publish-haddock Publish documentation to Hackage build Do a local pristine build from the tarball version Show the package version from .cabal file rename Rename the Cabal package github Add github repo ``` ## Details ### tagdist `hkgr tagdist` makes a dist tarball from a git tag: The `tagdist` command first reads the current package version (from the `.cabal` file in the current directory), and uses that to `git tag`. It then runs `cabal sdist` from a temporary pristine checkout of the tag to generate the dist tarball. Note that hkgr is lenient: it allows making a release with uncommitted changes in the working tree, but it will show the uncommitted changes. However the version must be committed. If the tag already exists (eg if you already ran `tagdist` earlier), and you need to add commits to the release you can use `--force` to move the tag to the latest commit and generate a new tarball off that, otherwise `tagdist` refuses to run again to prevent accidently overwriting the tag and dist tarball. One should not be able to `tagdist` on an already published (ie released) version made with hkgr, until the version is bumped. If sdist fails for some reason then hkgr tries to reset the tag. Alternatively if you have already manually tagged a release with 'v' prefix you can use `--existing-tag` to create a dist tarball. ### upload `hkgr upload` uploads the tarball to Hackage as a candidate release. Like `hkgr tagdist -f`, `hkgr upload -f` can be repeated. Haddock draft documentation can also be uploaded once if desired with `hkgr upload-haddock`. If you have an existing version tag (starting with `v`) you can use the `--existing-tag` option to skip the tagging step (like for `tagdist`). ### publish `hkgr publish` releases the tarball to Hackage, after doing a pristine local build and git pushing the tag and its commits to origin. If it succeeds, then hkgr creates a "published lockfile" in `.hkgr/`. (Then hkgr will refuse to do further commands on the released version.) Optionally one can publish haddock docs with `hkgr publish-haddock`. ### build `hkgr build` will try to do a pristine build of the latest created tarball for the tag. This is useful for catching missing files from the tarball, preventing brownbag releases. ### new `hkgr new` creates a new project. If you don't pass a name it will try to check the current directory. It uses `cabal init` to setup various files but replaces the .cabal file with a template stored in `~/.config/hkgr/template.cabal` which the user can freely customize. A `stack.yaml` file and git repo is also set up. ### github (One can use `gh repo create` etc to create the project repo on Github) and then `hkgr github` to add the github remote to your project. ## Requirements hkgr uses `cabal-install` >=2, `git`, and also `hlint` if available. ## Contribute `hkgr` is licensed and distributed under the GPL version 3 or later.
