Binary

Changes:

• The message formatting for the "show" subcommand was improved.
• In filter-specs for the "list" subcommand, a '=' is used for separating key and value when filtering for an exact value, rather than a ':'.

Added features:

• The "create-message", "new", "reply" and "tag" now accept the "--author" and "--date" options. Analogue to the options of "git commit" with the same name, the new options alter the author and authoring date of the resulting message.
• New "reporter-name" and "reporter-email" filter keys for issue filtering using the "list" subcommand. As the name suggests, the keys may be used for filtering issues based on the reporter's name or email.
• Filter specs for the "list" subcommand can now be used for filtering by substring or presence of a piece of issue metadata.
• Filter specs for the "list" subcommand can now be inverted.

Bug-fixes:

• Git-dit did not handle pager and editor flags correctly. For example, configuring less -R as the pager (contrary to less) would cause git-dit search for a binary named "less -R", resulting in an error.

Library

Changes:

• LineIteratorExt::stripped() now returns an iterator which also strips trailing blank lines.
• Issue::new() now returns a Result.
• Multi-line trailers parsed by the Blocks iterator are represented as String TrailerValue with newlines separating the individual lines from the input.
• trailer was promoted to a top-level module.
• message::accumulation was moved to trailer
• message::metadata was moved to trailer and renamed to spec.
• MetadataSpecification was renames to TrailerSpec.
• PairsToTrailers and DitTrailers iterator was moved to new trailers::iter module.
• Trailers iterator was moved to message::block module.
• DitTrailers is now a generic iterator adapter on top of an iterator over Trailers.

Added features:

• New TrailingBlankTrimmer for removing trailing blank lines from sequences of lines.
• New StrippingIter for stripping messages of comments and unnecessary white space.
• New TrailerFilter type for filtering based on trailers.
• New ValueMatcher type for matching TrailerValues.
• New MessagesExt convenience trait for iterators over messages. The trait provides accumulation functionality.
• New MultiAccumulator trait for map-based accumulation of multiple trailers.
• Implemented Default for TrailerValue.
• Implemented Clone for ValueAccumulator.
• Implemented From<Blocks> for Trailers

Documentation

• Add documentation of internals as a README.md to the sources of both the binary and the library.

Binary

Changes:

• "tag" now doesn't require a local head reference to be present in advance.
• "check-message" does not require a repository to be present any more.

Added features:

• New git-config option "dit.remote-prios" controlling how remote references are chosen for various actions.
• New "mirror" subcommand for mirroring remote references as local ones.
• New "gc" subcommand for collecting old references.
• New "check-refname" subcommand for extracting information from reference names.
• The "list" subcommand now supports a small set simple filters for filtering issues based on metadata.
• "get-issue-metadata" can now be used for querying a single piece of metadata.
• Example server-side update hook for a dit-only policy for repositories with global unauthenticated push access.

Bug-fixes:

• "fetch" and "push" tried fetching/pushing issues multiple times under some circumstances.
• "list" and "get-issue-tree-init-hashes" reported issues multiple times under some circumstances.

Library

Changes:

• RepositoryExt::issues_with_prefix() and RepositoryExt::issues() now return a unique set of issues.
• Issue::update_head() now takes an additional parameter controlling whether an existing head reference is replaced.
• Issue::messages_revwalk() was replaced by new Issue::messages() function.
• Issue::first_parent_revwalk() was replaced by new Issue::first_parent_messages() function.
• Function Issue::find_local_head() was renamed to Issue::local_head().
• Issue::local_refs() now has an additional parameter controlling the type of references returned.
• Issue::issue_leaves() was removed.
• message::line module was replaces by message::block module, including associated types.
• LineIteratorExt::categorized_lines() was replaced by LineIteratorExt::line_blocks().
• Message::categorized_body() was replaced by Message::body_blocks().
• TrailerValue::append() now operates in-place, on a mutable reference.

Added features:

• New type Messages for iterating over messages.
• New function Issue::terminated_messages() for preparing a Messages instance which terminates at the initial message.
• New function Issue::messages_from() for creating a Messages instance returning messages from one specific commit to the initial message.
• New module message::accumulation for accumulating issue metadata.
• New module message::metadata providing specification of a small set of predefined pieces of issue metadata
• New type IssueRefType representing the type of a reference (e.g. "head" or "leaf").
• New PairsToTrailers iterator for assembling trailers from key-value pairs.
• New Issue::remote_refs() and Issue::all_refs() functions for retrieving references.
• Implemented PartialEq, Eq and Hash for Issue.
• Implemented From<Messages> for IssueMessagesIter.
• Implemented AsRef<String> for TrailerKey

Bug-fixes:

• Fixed lifetimes of return values of several Issue functions.

Documentation

• Building the manpage is now controlled via the manpage feature rather than an environment variable.
• The subcommand descriptions are now longer set as code snippets.
• Various small fixes and updates.

Changes:

• Add WORKFLOWS section to the man page
• Clarify implementation of metadata "tags" in the documentation
• Clarify membership of initial issue messages to branches in man page
• Fix punktuation issues in the man page

Bug-fixes:

• Fix bug in Trailers iterator which caused emission of trailers even if they are embedded in a block of text.

Changes:

• Rewrite in Rust (single binary)
• Drop "prepare-metadata" script
• "push" and "fetch" now only support dummy auth and ssh-agent
• Updated README
• Updated man page

Added features:

• Documentation of data model, semantics and use-cases
• Library crate "libgitdit"
• Long options

Bug-fixes:

• Read editor from git config, fall back to default (We previously relied on the EDITOR variable.)
