Minilla - CPAN module authoring tool


    minil new     - Create a new dist
    minil test    - Run test cases
    minil dist    - Make your dist tarball
    minil install - Install your dist
    minil release - Release your dist to CPAN
    minil run     - Run arbitrary commands against build dir


Minilla is a CPAN module authoring tool. Minilla provides minil command for authorizing a CPAN distribution.

    (M::I - inc) + shipit + (dzil - plugins)


As stated above, Minilla is opinionated. Minilla has a bold assumption and convention like the followings, which are almost compatible to the sister project Dist::Milla.

Your modules are written in Pure Perl and are located in lib/.
Your executable files are in script/ directory, if any
Your module is maintained with Git, git ls-files matches with what you will release and your remote is named origin
Your module has a static list of prerequisites that can be described in cpanfile
Your module has a Changes file
Your module requires at least perl 5.6.


    # First time only
    % cpanm --with-recommends Minilla
    # Minilla has only a few deps. It should be very quick

    # Make a new distribution
    % minil new Dist-Name
    % cd Dist-Name/

    # Git commit
    % git commit -m "initial commit"

    # Hack your code!
    % $EDITOR lib/Dist/ t/dist-name.t cpanfile

    # Done? Test and release it!
    % minil release

It's that easy.

You already have distributions with Module::Install, Module::Build, Dist::Zilla or ShipIt? Migrating is also trivial. See "MIGRATING" in Minilla::Tutorial for more details.


Repository managed by Minilla is git install ready.

The repository created and managed by Minilla is git install ready. You can install the library by cpanm git://....

Of course, you can install Minilla from cpanm git://

Minilla is built on small libraries.

Minilla is built on only few small libraries. You can install Minilla without a huge list of dependencies to heavy modules.

And, what is Minilla?

    Minilla is a Kaiju (Japanese giant monster) from the Godzilla series of films and is the first of several young Godzillas.

Minilla's release process

Minilla's release process is the following.


Checking git's untracked files. If there's untracked files, minilla will abort.


This step will run the `git remote`. If there's no remote, minilla will abort.


Checking git's current branch is `release.branch` key in minil.toml. If no match, minilla will abort.


Minilla will show 'Next Release?' prompt. You can input next version number.

After that, minilla rewrites version numbers in **/*.pm, **/*.pl, and a script file contains perl-ish shebang.


You need to write Changes file. Your module's users need to know the difference between versions.

Minilla's Changes file includes `{{$NEXT}}` next version indicator. You should put update informations after that.


In this step, minilla will regenerate META.json, and (Makefile.PL|Build.PL).


This step runs commands listed on `release.hooks` key in minil.toml.


This script runs test cases in clean working directory with $ENV{RELEASE_TESTING} = 1.


Make distribution tar ball.


Upload your module to CPAN.


Rewrite Changes file. Minilla replaces {{$NEXT}} with released version number and current date & time. And put {{$NEXT}} on the first line.


Commit current directory with automatically generated commit message from Changes file. And push it to origin.


Create new git tag and push it to origin.


Minilla uses Convention over Configuration.

But, you can write configurations to minil.toml file in TOML format. Minilla reads the minil.toml file in the root directory of your project.


You can write 'name' instead of automatically detecting project name out of the directory name.


Minilla supports three module building mechanisms. Module::Build::Tiny is the default one and Module::Build or ExtUtils::MakeMaker are the alternatives. See also FAQ section in this document.


You can specify the file to generate the This is a main module path by default.


format of the tag to apply. Defaults to %v. %v will replace with the distribution version.


Grab abstract information from the file contains pod.


Grab authors information from the file contains pod.

    authority = "cpan:TOKUHIROM"

Set x_authority attribute to META. See for more details. Note that now PAUSE itself copies the permissions from the "main module" to any new modules entering the index for the first time, so you don't need to set this attribute anymore.


A boolean indicating the module is still functional without its XS parts. When an XS module is build with --pureperl_only, it will otherwise fail.

It affects to Module::Build 0.4005+ only.


Minilla sets bugtracker to github/GitLab's issue tracker by default. But if you want to use RT, you can set this variable.

    directory=['t', 'xt', 'tools']

Minilla sets META.json's no_index as directory => ['t', 'xt', 'inc', 'share', 'eg', 'examples', 'author', 'builder'] by default. But if you want to change them, you can set this section variable. If this section is set, specified variables are only used, in fact default settings are not merged.

    c_source = ['src']

A directory which contains C source files that the rest of the build may depend on. Any ".c" files in the directory will be compiled to object files. The directory will be added to the search path during the compilation and linking phases of any C or XS files.

    script_files = ['bin/foo', 'script/*']

Minilla sets install script files as ['script/*', 'bin/*'] by default.

(Note. This option doesn't affect anything if you are using ModuleBuildTiny or ExtUtilsMakeMaker, for now. If you are using ModuleBuildTiny, you MUST put scripts in script/ directory.)


This parameters pass to TAP::Harness when running tests. See the TAP::Harness documentation for details.


You can specify your favorite license on minil.toml. The license key is same as CPAN Meta spec 2.0. See CPAN::Meta::Spec.

    badges = ['', '', 'circleci', 'appveyor', 'coveralls', 'codecov', 'gitter', 'metacpan', 'kritika', 'github-actions/$workflow_file', 'gitlab-pipeline', 'gitlab-coverage']

Embed badges image (e.g. Travis-CI) to It ought to be array and each elements must be service name. Now, supported services are '', '', 'circleci', 'appveyor', 'coveralls', 'codecov', 'gitter', 'metacpan', 'kritika' 'github-actions', 'gitlab-pipeline' and 'gitlab-coverage'.

You can send additional parameters as required by your CI provider by including a query string along with your service name: e.g. travis?token=[YOUR_TOKEN_GOES_HERE]&branch=dev


Specify the PL files.


This option is not supported by Minilla::ModuleMaker::ModuleBuildTiny.

Note. MBTiny executes *.PL files by default.


Specify a custom Module::Build subclass.

    build_class = "builder::MyBuilder"
    needs_compiler_c99 = 1

You can specify needs_compiler_c99 parameter of Module::Build::XSUtil.

    needs_compiler_cpp = 1

You can specify needs_compiler_cpp parameter of Module::Build::XSUtil.

    generate_ppport_h = 1

You can specify generate_ppport_h parameter of Module::Build::XSUtil.

    generate_xshelper_h = 1

You can specify generate_xshelper_h parameter of Module::Build::XSUtil.

    cc_warnings = 1

You can specify cc_warnings parameter of Module::Build::XSUtil.

    exclude_match = ['^author_tools/.*']

Nothing by default. To exclude certain files from being gathered into dist, use the exclude_match option. Files matching the patterns are not gathered.

    include_dotfiles = false

By default, files will not be included in dist if they begin with a dot. This goes both for files and for directories.

In almost all cases, the default value (false) is correct.

    pause_config = "/path/to/some/.pause"

By setting this value to another PAUSE configuration file (see "CONFIGURATION" in cpan-upload for the details), it is possible to use another PAUSE server (or anything good enough to mimick its upload process) for the release step.

To do so, simply add a upload_uri entry in your file to the alternate PAUSE server, i.e :


If you instantly launch your origin upload server as DarkPAN, See OrePAN2::Server.


This variable disables CPAN upload feature.

    hooks = [

Commands that are specified by this option will be executed when releasing. If result of commands is not successful, it will abort.

    branch = "main"

If this value does not match the current branch, it will abort.

    os = [

By setting this value to add unsupported OS checks for (Build.PL|Makefile.PL).

    MinimumVersion = false

If you set this key false, Minilla will not generate 'xt/minilla/minimum_version.t'.


The requires_external_bin command takes the name of a system command or program. Build fail if the command does not exist.

    markdown_maker = "Pod::Markdown::Github"

Use a different module to generate from your pod. This module must subclass Pod::Markdown.

    x_deprecated = 1

Add arbitrary keys to META.json/META.yml.

    static_install = "auto"

If static_install = "auto" (or nothing is specified at all), then minil tries to detect whether distributions are ready for static install or not, and set x_static_install in META files accordingly. You can also set static_install = 0/1 explicitly; then minil will respect it.

For static install itself, please refer to


How can I manage contributors section?

Minilla aggregates contributors list from git log --format="%aN <%aE>" | sort | uniq.

You can merge accounts by .mailmap file. See

Why don't you provide plug-in support?

If you want a pluggable tool, it already exists: It's called Dist::Zilla :P If you like Minilla's behavior but you really want something pluggable, you can use Dist::Milla, Minilla's sister project. Dist::Milla's behavior is almost identical to that of Minilla.

Why does minil only support git?

I think git is a best VC for CPAN modules, for now.

If you want to use another version control system, you can probably use Dist::Milla.

And why...

Yes. You can use Dist::Milla.

Should I add (META.json|Build.PL) to repository?

Yes. You need to add it to make your git repo installable via cpanm.

How do I manage ppport.h?

Is there a reason to remove ppport.h from repo?

How can I install script files?

Your executables must be in script/ directory.

How to switch from Module::Install/Module::Build/Dist::Zilla?

You can use experimental `minil migrate` sub-command. See Minilla::CLI::Migrate for more details.

How should I manage the files you do not want to upload to CPAN?

Please use FileGatherer.exclude_match for ignoring files to upload tar ball.

You can use MANIFEST.SKIP file for ignoring files. ref. ExtUtils::Manifest.

How do I use Module::Build::Tiny with Minilla?

Minilla supports Module::Build::Tiny and uses it as a default installer since v1.0.0.

If you want to migrate an existing project created before Minilla v1.0, you need to rewrite minil.toml file. You need to add the following line:

How do I use Module::Build with Minilla?

If you want to create new project with Module::Build, run the command as following.

    % minil new -p ModuleBuild My::Awesome::Module
How do I use ExtUtils::MakeMaker with Minilla?

Minilla v2.1.0+ supports EUMM(EXPERIMENTAL).

You need to rewrite minil.toml file and add the following line:


(There is no profile, yet. Patches welcome.)

I don't suggest to use this module... But you can use this option for maintaining primitive modules like Test::TCP.

Ho do I support Perl 5.6?

EUMM can run on Perl 5.6. Write following statement in your minil.toml file.


bash/zsh completion

Minilla provides bash and zsh completion files under contrib/ directory.
