feat(tera): add haiku() function for random name generation by jdx · Pull Request #7399 · jdx/mise

jdx · 2025-12-18T22:10:19Z

Summary

Adds a new Tera template function haiku() that generates random names like silent-forest-42.

Options:

Parameter	Default	Description
`words`	2	Number of words
`separator`	`-`	String between parts
`number`	true	Include trailing number
`number_max`	99	Maximum number value

Examples:

{{ haiku() }}                              -> "ancient-moon-73"
{{ haiku(words=3) }}                       -> "cold-river-wild-15"
{{ haiku(number=false) }}                  -> "hidden-butterfly"
{{ haiku(separator="_", number_max=999) }} -> "misty_dawn_847"

Use cases:

Unique session IDs
Temporary file/directory names
Test data generation
Human-readable identifiers

Word lists inspired by https://github.com/nishanths/rust-haikunator

🤖 Generated with Claude Code

Note

Introduce haiku() Tera function for human-readable random names with tests; update key dependencies (e.g., xx 2.3.0, zip 6.0.0) and allow CC0-1.0 license.

Tera:
- Add haiku() function with options words, separator, and digits using xx::rand::haiku.
Tests:
- Add test_haiku covering defaults and custom options.
Dependencies:
- Bump xx to 2.3.0; update zip to 6.0.0 (adds ppmd-rust, lzma-rust2 0.13.0, etc.).
- Align various transitive versions (e.g., windows-sys downgrades across crates, base64 for oauth2).
Licenses/Policy:
- Add CC0-1.0 to deny.toml allowed licenses.

Pull request overview

This PR adds a new random_name() Tera template function that generates random, human-readable identifiers in the format adjective-noun-number (e.g., flying-rabbit-23). This is useful for creating unique session IDs, temporary names, or test data.

Key Changes:

Implements random_name() function with 64 adjectives and 64 nouns, generating numbers from 1-99
Adds test coverage verifying the output format (3 dash-separated parts with parseable number)

+                "wave",
+                "water",


Duplicate entry: 'water' appears twice in the NOUNS array (lines 214 and 217). Remove one occurrence to maintain the claimed count of 64 unique nouns.

Duplicate entry: 'sun' appears twice in the NOUNS array (lines 187 and 219). Remove one occurrence to maintain the claimed count of 64 unique nouns.

+            let adj = ADJECTIVES.choose(&mut rng).unwrap();
+            let noun = NOUNS.choose(&mut rng).unwrap();


The ADJECTIVES and NOUNS arrays are recreated on every function call. Consider moving these const arrays outside the closure to avoid repeated allocations and improve performance when this function is called frequently.

+            let adj = ADJECTIVES.choose(&mut rng).unwrap();
+            let noun = NOUNS.choose(&mut rng).unwrap();
+            let num: u32 = rng.random_range(1..100);


The range 1..100 generates numbers from 1-99, but the PR description claims this gives ~400k unique combinations. With the current implementation: 64 adjectives × 64 nouns × 99 numbers = ~406k combinations. However, due to the duplicate entries in NOUNS, the actual count is lower. Update either the word lists or the documentation to be accurate.
