Patchloom 0.32.0
YAML merge-key edits keep shared mappings, sibling anchors, and
comments instead of rewriting the whole file. Patch deletes report
a change and apply hunks before unlink, so leftover lines stay on
disk.
Highlights
doc set on a YAML merge (<<: *shared) now keeps the merge key
when you grow an inherited array, delete an inherited field, or
write an empty object. Sibling &anchor lines stay. Empty {}
and [] keep comments and spacing instead of rewriting the
whole file.
apply_patch on a git delete reports changed: true and empty
new_content. A hunked +++ /dev/null applies the minus lines
first. Leftover text is written back. A stale minus is
error_kind: ambiguous (exit 5) and the file is left unchanged.
New features
- Library doc_keys and doc_len. Hosts can list object keys
and count array or object length without going through CLI or
MCP. Empty / "." is the document root. An array on doc_keys
is type_error. A wildcard or predicate (items[*]) is
ambiguous and names items[0] / items[1]. A missing file
is not_found.
let keys = patchloom::api::doc_keys(path, "database")?;
let n = patchloom::api::doc_len(path, "items")?;
CLI doc keys / doc len and MCP doc_query use the same
rules (#2282, #2284).
- Blank YAML is an empty object on read. doc keys, doc len, and doc get . treat an empty, whitespace-only, or
BOM/ZWSP-only YAML file as {}. Comment-only YAML, null,
and a bare --- still return type_error on keys and len (#2285, #2286).
- Protobuf AST kinds. ast list and ast rename on .proto
files include Status and enum symbols. Kind filters accept
message, service, and rpc as well as the tree-sitter
names (#2264, #2265).
Bug fixes
- YAML merge edits dumped the file or dropped <<:. Growing
an inherited array, deleting an inherited key, or expanding a
merge-only site now keeps the merge key, sibling anchors, and
comments. A merge-only site that becomes empty writes {} (#2270, #2271, #2272, #2273).
- Emptying a YAML sequence item glued the next line. Setting
a non-last item to {} or [] used to drop the item newline
(- {} - name: B) and dump the file. The item stays on its
own line and comments remain (#2277, #2281).
- Mixed flow and block aliases dumped the file. A flow
[*shared] next to a later - *shared no longer rewrites the
whole document. Merge-key walks stop at depth 128 (#2267, #2265).
- apply_patch delete looked unchanged. An empty-hunk git
delete (deleted file mode, no hunks) now reports
changed: true and empty new_content. Regular files are
snapshotted for undo. Symlink, FIFO, and socket snapshots stay
empty so target bytes are not copied into the result (#2287, #2289).
- Hunked delete unlinked first and dropped leftover lines. A
+++ /dev/null patch with minus hunks now applies those hunks
before unlink. Leftover text is written back. A stale minus is
ambiguous (exit 5) and the file stays (#2294).
- Add-only hunks wiped a symlink target. Content patches load
the symlink target instead of treating every special path as
empty. Empty-hunk delete snapshots stay empty (#2293).

Upgrading
- Agents: doc keys / doc len on a wildcard or predicate
(items[*]) is ambiguous, even when there is one match. A
missing file is not_found. Blank YAML keys/len/get treat the
document as {}.
- Library hosts: api::doc_keys and api::doc_len are new.
apply_patch empty-hunk delete now sets changed: true and
empty new_content. Hunked +++ /dev/null applies minus lines
first; leftover text is a write, not an unlink. Content patches
follow symlink targets. Empty-hunk delete snapshots of symlink,
FIFO, and socket stay empty.
- MCP / --contain: a leftover rewrite through a workspace
symlink that points outside the workspace is rejected. CLI
without --contain still follows the path the user passed.
- Install from crates.io, npm, Homebrew, or Scoop after the tag
ships. On Windows, Scoop is recommended; winget may need
winget source update after Microsoft publishes; Chocolatey can
lag while moderation runs.
