HashlinePatcher class final

High-level patcher. Wires an ExecutionEnv and a HashlineSnapshotStore together with the parsing + applying core. Construct once per session; reuse across patches.

Constructors

HashlinePatcher({required ExecutionEnv env, required HashlineSnapshotStore snapshots, bool enforceSeenLines = true})
Creates a patcher over env with the session snapshots store.

runtimeType → Type

no setterinherited
snapshots → HashlineSnapshotStore
Snapshot store that minted and resolves hashline section tags.

Methods

apply(HashlinePatch patch) → Future<HashlinePatcherApplyResult>
Applies every section in patch. prepare runs the full apply for each section in memory before any write hits the filesystem, so a multi-section batch is naturally all-or-nothing. Returns one HashlineSectionResult per section in the original patch order.
commit(HashlinePreparedSection prepared) → Future<HashlineSectionResult>
Commits a previously prepared section to the filesystem. Restores line endings and BOM, writes via the env, and records a fresh snapshot in the store keyed by the env-canonical path.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.

prepare(HashlinePatchSection section) → Future<HashlinePreparedSection>
Reads a section's target file, parses the section, validates the snapshot tag, and applies the edits in memory. Returns a HashlinePreparedSection which can be fed to commit to land the result on the filesystem.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
