v5.0.0

All changes are non-functional - there are no changes to the API or app behaviour.

Breaking changes since v4

• Drop support for node versions less than v18.

v4.0.0

All changes are non-functional - there are no changes to the API or app behaviour.

Breaking changes since v3.2.1

• Removed CommonJS distribution. The codebase is now ESM only.
  • This is due to rollup (used to create the CJS dist) not having good support for dynamic imports (required by renamer's plugin loader).
  • This change only affects API (not CLI) users that use require to load renamer.

Other non-functional changes

• Extended support back to v12.17 (previously v14 was required).
• Renamed all source filename extensions from .mjs to .js

Upgrade notes

• CommonJS users that load renamer using require should not upgrade to v4 - stick with versions 1, 2 or 3 until able to load ECMAScript modules.
• There are no other changes. All other users can safely upgrade. Node >=v12.17 users may now also upgrade.

v3.0.0

Breaking changes since v2.0.1

• Support dropped for Node.js versions less than v14.
• Small change to Replace chain plugin API: the plugin module should now export a plain class instead of a decorator function as before
  • The previous method prevented the user from defining a plugin which extended his/her own base plugin class.
• The Renamer class is no longer an EventEmitter. Rather than listen for replace-result events you now async iterate over renamer.results.
  • renamer.results example
  • renamer.rename example
  • API docs
• The renamer.rename API method is now asynchronous, returning a Promise. Previously it was synchronous.
• The --plugin option has been renamed to --chain
  • This is because both replace chain and --view plugins are now accepted, making the previous name --plugin ambiguous.

New features

• Added ability to create and use custom views
• Added --silent mode
• Added --view one-line which outputs just a summary line, nothing more. #49
• Added some basic stats (e.g. 2 of 3 files renamed) to the built-in views
• Added renamer.results async iterator to the core API.

Other changes

• Source code rewritten as ECMAScript Modules.
• All synchronous I/O rewritten as asynchronous, which should yield some performance improvements on large batch renames.
• Dependency tree refreshed and updated
• Wiki docs updated

Upgrade notes

• Regular renamer CLI use (e.g. everything documented on the examples page) is unchanged. Only API consumers plus replace chain plugin authors and users will have any changes to make.

v2.0.0

Breaking changes since 1.1.4

• Dropped support for Node.js versions less than v10

v1.1.0

New features since v1.0.0

Added --index-root.

By default, the {{index}} value begins at 1. You can override this by specifying an --index-root value.

$ renamer -d --replace "Image{{index}}.jpg" --index-root 10 *

v1.0.0

Renamer has been completely rewritten but retains its core behaviour and "feel".

Breaking changes since v0.7.0

• It requires node v8.9.0 or above.
• The programmatic API has been rewritten. Documentation for the new API is here.
• --regex and --insensitive options removed, you now specify a regular expression literal. For example, --find '/something/ig'.
• The number replacing the {{index}} token is now incremented per file-renamed-successfully, rather than per file.

New features

• Added the ability to specify which --path-element should be renamed.
• Plugin system added.
• --force mode added, fixes #17.
• --view long and --view diff added.
• A file list can now be passed into stdin, facilitating use of tools like find to build the input file list. Users now have control over the input file order and therefore {{index}} value. Fixes #31.

Documentation

• Wiki added.
• API docs added.

Upgrade notes

Quite a lot has changed so it's worth reading the new documentation. Nevertheless, the core user-experience remains largely the same: you set a --find, --replace, some files, check the --dry-run then rename.
