Explain the second and third return values: match and maxlen.
lib/uuid: return nil if ID is zero2026-04-12T21:27:12ZShulhanms@kilabit.info2026-04-12T20:12:16Zurn:sha1:a7e8750d5b83f390afec2333350a7293917dee12
Per RFC 9562 Section 5.9,
A Nil UUID value can be useful to communicate the absence of any
other UUID value in situations that otherwise require or use a
128-bit UUID.
A Nil UUID can express the concept "no such value here".
Thus, it is reserved for such use as needed for
implementation-specific situations.
In case of SQL, the Value method should return nil if ID is zero.
lib/memfs: fix due to changes on [text/diff] package2026-04-12T15:36:59ZShulhanms@kilabit.info2026-04-12T14:57:24Zurn:sha1:beccc10bc2fd1b80134c7acd5e180b9d31c7fb4etext/diff: skip writing Unified if no difference found2026-04-12T15:33:31ZShulhanms@kilabit.info2026-04-12T14:37:49Zurn:sha1:e1b84ebc2a06d28cc1890e0eee69632363bb961flib/test: rewrite Assert to use [diff.Unified]2026-04-12T15:33:31ZShulhanms@kilabit.info2026-04-12T14:20:40Zurn:sha1:c1a33bead8068e02c34fafb09c5519d5e5c18706
Using diff Unified improve the test output readability when two large
strings are not match.
text/diff: rename LevelWords to LevelChunks2026-04-12T13:35:18ZShulhanms@kilabit.info2026-04-12T13:35:12Zurn:sha1:05849aa15abc0bcfc6a76fc86af2ef6590023ce2
Using Words seems like misleading since we capture the characters
difference, not a word as in human language.
text/diff: rewrite TestText to test Files with LevelWords2026-04-12T13:29:02ZShulhanms@kilabit.info2026-04-12T11:49:32Zurn:sha1:986ad438d702ebf7d2604def94eaf3e807be7cfd
In the struct Data, we add new method WriteLineChunks to print the
LineChunks data into [io.Writer] w.
text/diff: rename LineChange to LineChunk2026-04-12T12:52:06ZShulhanms@kilabit.info2026-04-12T12:52:06Zurn:sha1:c708197eceaee50d29801cff63124a146139e969
In the struct Data we also rename field Changes to LineChunks.
text/diff: remove LineChanges2026-04-12T12:08:21ZShulhanms@kilabit.info2026-04-12T12:07:51Zurn:sha1:26a02a8396684fcb58f4ba431ae5ae799eb35d68
Defining []T as new type does not help on readability only make it
confusing for future maintenances.
text/diff: add example for Files, Lines, Text, and Unified2026-04-12T12:01:45ZShulhanms@kilabit.info2026-04-12T10:38:32Zurn:sha1:bfa79cf52d62418f622289cee7c1fe5807c73be6
While at it,
- reorganize the order of functions alphabetically, following
the order from doc.
- changes the [Line.String] to print text in double quoted to help human
compare the changes for non-printable characters.
