This adds a `Livecheck::Options` class, which is intended to house
various configuration options that are set in `livecheck` blocks,
conditionally set by livecheck at runtime, etc. The general idea is
that when we add features involving configurations options (e.g., for
livecheck, strategies, curl, etc.), we can make changes to `Options`
without needing to modify parameters for strategy `find_versions`
methods, `Strategy` methods like `page_headers` and `page_content`,
etc. This is something that I've been trying to improve over the years
and `Options` should help to reduce maintenance overhead in this area
while also strengthening type signatures.
`Options` replaces the existing `homebrew_curl` option (which related
strategies pass to `Strategy` methods and on to `curl_args`) and the
new `url_options` (which contains `post_form` or `post_json` values
that are used to make `POST` requests). I recently added `url_options`
as a temporary way of enabling `POST` support without `Options` but
this restores the original `Options`-based implementation.
Along the way, I added a `homebrew_curl` parameter to the `url` DSL
method, allowing us to set an explicit value in `livecheck` blocks.
This is something that we've needed in some cases but I also intend
to replace implicit/inferred `homebrew_curl` usage with explicit
values in `livecheck` blocks once this is available for use. My
intention is to eventually remove the implicit behavior and only rely
on explicit values. That will align with how `homebrew_curl` options
work for other URLs and makes the behavior clear just from looking at
the `livecheck` block.
Lastly, this removes the `unused` rest parameter from `find_versions`
methods. I originally added `unused` as a way of handling parameters
that some `find_versions` methods have but others don't (e.g., `cask`
in `ExtractPlist`), as this allowed us to pass various arguments to
`find_versions` methods without worrying about whether a particular
parameter is available. This isn't an ideal solution and I originally
wanted to handle this situation by only passing expected arguments to
`find_versions` methods but there was a technical issue standing in
the way. I recently found an answer to the issue, so this also
replaces the existing `ExtractPlist` special case with generic logic
that checks the parameters for a strategy's `find_versions` method
and only passes expected arguments.
Replacing the aforementioned `find_versions` parameters with `Options`
ensures that the remaining parameters are fairly consistent across
strategies and any differences are handled by the aforementioned
logic. Outside of `ExtractPlist`, the only other difference is that
some `find_versions` methods have a `provided_content` parameter but
that's currently only used by tests (though it's intended for caching
support in the future). I will be renaming that parameter to `content`
in an upcoming PR and expanding it to the other strategies, which
should make them all consistent outside of `ExtractPlist`.
We recently updated the `Pypi` strategy to use the PyPI JSON API and
the default strategy behavior no longer relies on a regex, so the initial implementation didn't include regex handling. This restores
support for a `livecheck` block regex by updating the `DEFAULT_BLOCK`
logic to handle an optional regex. This allows us to use a regex to
omit parts of the `info.version` value without having to duplicate
the default block logic in a `strategy` block only to use a regex.
This isn't currently necessary for any existing formulae using the
`Pypi` strategy but we have a few that needed a custom regex with
the previous strategy approach, so they may need this functionality
in the future. Besides that, restoring regex support to `Pypi`
ensures that `livecheck`/`strategy` blocks work in a fairly
consistent manner across strategies.
This reworks the new `Pypi` JSON API implementation to use
`Json::find_versions` in `Pypi::find_versions`, borrowing some of the
approach from the `Crate` strategy.
Besides that, this pares down the fields in the
`::generate_input_values` return hash to only `:url`, as we're not
using a generated regex to match version information in this setup.
This adds a `provided_content` parameter to `::find_versions` as part
of this process and I will expand the `Pypi` tests to increase
coverage (like the `Crates` tests) in a later PR. 75% of `Pypi` checks
are failing at the moment (with some returning inaccurate version
information), so the current priority is getting this fix merged in
the short-term.
livecheck is returning an `Unable to get versions` error for the
`ansible-lint`, `aws-sam-cli`, and `pyqt-builder` formulae. These use
the `Pypi` strategy without a `livecheck` block, so they use the
generated regex from the strategy. The `Pypi` strategy matches the
version from the tarball link on the pypi.org package page but this
fails for these packages because the formula's `stable` tarball uses
hyphens in the filename (e.g., `ansible-lint-...`) but the current
tarball filename uses underscores (e.g., `ansible_lint-...`).
This addresses the issue by updating the strategy regex to replace
[escaped] `-` or `_` characters in the package name with `[_-]`, so
the regex will match regardless of the delimiter used in the formula
filename.
There are times where a regex isn't needed in a `strategy` block and
these changes explicitly handle that situation.
This allows the Symbol Proc format used in some `Sparkle` `livecheck`
blocks (e.g., `strategy :sparkle, &:version`) to continue working
instead of failing with a "wrong number of arguments (given 1,
expected 0)" error. This error would occur because a Symbol Proc only
only expects one argument (e.g., an `Item`, not an `Item` and a
regex/nil).
There's an argument to be made for avoiding the Symbol Proc format
for `strategy` blocks but I haven't found a way of selectively
disabling the Style/SymbolProc cop only for a `strategy` DSL method
call. That is to say, if we don't use the Symbol Proc format, `brew
style` will give a "Pass &:version as an argument to strategy instead
of a block." offense.
Besides that, this also replaces the `block` type signatures in
livecheck strategies with `T.untyped`. Sorbet doesn't know how to
handle a `Proc` with a variable number of arguments and can't be
taught how (i.e., `T.any` with a `Proc` signature for each variation
doesn't work). The aforementioned changes cause Sorbet to complain
about there being both too many and too few arguments, so the only
way to win is not to play the game. Hopefully we can restore the
`block` type signatures in the future (if upstream resolves this
years-old issue) but `T.untyped` seems to be our only option for now.
