* use `~/.cache/tailwindcss` as default touch dir
When more tools catch up with the latest postcss dependency tracking,
then we probably don't even need this anymore. However, it is a good
practice to put (global) caches in ~/.cache and (global) configs in
~/.config
Fixes: #4569
* change test to verify @tailwind base slightly
Because of some changes in tailwind itself, the base selector contains a
ton of new --tw-* custom properties. Keeping this up to date might be a
bit of an annoying challenge. So instead we now check for the selector
to be present.
* add `tmp` package
* use a (simple) temporary file, instead of a full cache dir
* add tests for the --postcss option in the new CLI
* add `oneOf` ability to the `arg()` functionality
By default, `arg()` doesn't have a way to define multiple types. We want
the possibility of using `--postcss` (Boolean) or `--postcss
./custom-path.js`. But by default this is not possible.
This commit will allow us to do a few things, mainly:
- Keep the same API using the `{ type: oneOf(String, Boolean), description: '...' }`
- Keep the `--help` output similar
What we did behind the scenes is make sure to put the non recognized
flags in the `_` arguments list. This is possible by doing `permissive:
true`. We then manually parse those and resolve the correct value.
* ensure that we can use a custom `--postcss ./with-custom-path.js`
* fix --help output in tests
* add tests to ensure we can use `purge.safelist`
* implement the `purge.safelist` for strings
* proxy `purge.safelist` to `purge.options.safelist`
This allows us to have a similar API in `AOT` and `JIT` mode.
* only proxy `purge.safelist` to `purge.options.safelist` if
`purge.options.safelist` doesn't exists yet.
* remove unused file
using syntax.js instead
* add a way to remove files that are generated from the tests
Essentially setting the restore cache contents to `null` as a special
value.
* combine the stdout and stderr output
* add jest-diff instead of relying on it existing *somewhere*
This also came with a small API change.
* add `--runInBand` to the test script
* add dedicated cli tests for the new Tailwind CLI
