fish SlackBuild – vendored Rust dependencies
===========================================

This SlackBuild vendors Rust dependencies to allow a fully offline
and reproducible build, as required by SlackBuilds.org.

1) fish vendor tarball
----------------------

The file:

  fish-<version>-vendor.tar.gz

contains all Rust crates required by fish and was generated on a
system with network access.

Steps to regenerate (run in the fish source tree):

  $ cargo vendor vendor
  $ tar czf fish-<version>-vendor.tar.gz vendor

During the SlackBuild, this tarball is unpacked and Cargo is forced
to use it via:

  .cargo/config.toml
  CARGO_NET_OFFLINE=true

This prevents any access to crates.io during the build.

2) rust-pcre2
-------------

fish depends on rust-pcre2, which upstream fetches via git.
To keep the build offline, rust-pcre2 is provided as a separate
tarball:

  rust-pcre2-0.2.9-utf32.tar.gz

Cargo.toml is patched to use this local path instead of the git
repository.

3) Updating to a new fish version
---------------------------------

When updating fish:

  - Update VERSION in the SlackBuild
  - Regenerate fish-<version>-vendor.tar.gz
  - Update checksums in fish.info

No network access should be required when running the SlackBuild.
