Closes#489.

Changelogs:

• Added--use-bun flag, similar to the current--use-yarn flag.
• AddedparseBunLockfile.ts to convert bun.lockb into yarn v1 lockfiles.
• UpdatedgetPackageResolution.ts to handle bun conversions before parsing.
• UpdateddetectPackageManager.ts to detect bun, bun workspaces and multiple lockfiles.
• Updated README with setup instructions for Bun.

Caveats:

• If user has multiple lockfiles, patch-package uses npm by default. However, in the rare case where only bun.lockb and yarn.lock files exist, we have to resort to using yarn. This behaviour has been documented in the CLI and README (see0491b91).
• Currently awaiting confirmation on how Bun handles postinstalls, for writing up the README about bun setup. (Willbun remove execute postinstall scripts? If not, bun users should also installpostinstall-postinstall just like yarn v1 users.)
  • Confirmed byfeat: add preliminary support for Bun #490 (comment).
  • Fixed by7482db9.
• Currently awaiting confirmation on how Bun workspaces work, for writing up the README about bun workspaces setup (Is it similar to yarn workspaces, where users need to "repeat the setup process for the child package" if they want to patch un-hoisted packages?)

Temporary workaround (while this PR is unmerged):

• Citingsupport patching dependencies, similar topnpm patch/patch-package oven-sh/bun#2336 (comment),

  Attempting to create a patch usingbunx patch-package <package-name> fails.

  However, if you have pre-existing patches in the./patches directory, you can successfully apply them using thebunx patch-package command (or via package.json -> scripts ->"postinstall": "patch-package")

  As a temporary workaround to generate apatches/package+name+version.patch file

  • runbun install --yarnit just converts bun.lockb into a yarn.lock. (orbun ./bun.lockb > ./yarn.lock)
  • make the necessary modifications insidenode-modules/<package-name>
  • bunx patch-package <package-name>
  • rm yarn.lock
  • package.json -> scripts ->"postinstall": "bunx patch-package"
