README
Provides a metapackage for library needing intl
that fallback to a default implementation when user does not meet
the initial requirements.
Usage
composer require "composer-fallback/intl.symfony-polyfill:*"
Composer will, by preference:
- check if user has
ext-intl
- otherwise, fallbacks to
symfony/intl
How does it works
This package contains 2 versions:
Composer will choose this highest version when user has the extension ext-intl.
Otherwise, composer will choose the lowest version and in that case will
download the following packages: symfony/intl
.
What problem does it solve?
You are maintaining a library that need an implementation of intl
,
but you don't want requiring a specific implementation.
ie. you need function defined in intl
, but polyfill exists and would be enough.
When end users requires you library with the following code
{ "name": "end-user/app", "require": { "acme/lib": "^1.0" } }
They probably ends with such error
composer up Your requirements could not be resolved to an installable set of packages. Problem 1 - Installation request for acme/lib ^1.0 -> satisfiable by acme/lib[1.0]. - acme/lib 1.0 requires ext-intl * -> no matching package found.
You can ask user to install a random package, it works, but the DX is very bad, and confusing at first.
By using composer-fallback/intl.symfony-polyfill
,
users will provide the native implementation
or fallback to your default choice
Example of user that meet the preferred requirements
