Cliffy 1.2.0: fuzzy search, word navigation, and completeOnSubmit

Long option lists are hard to navigate with arrow keys alone. Select and checkbox prompts already supported search, and the matching behind it is now a searchMode option with four strategies:

• "substring", a classic contiguous match.
• "fuzzy", the typed characters in order but with gaps allowed, so strubu finds structure-builder.
• "typo", tolerating misspellings, so stroberry finds strawberry.
• "all", which combines the three and is the default.

So a searchable prompt gets fuzzy and typo matching without asking for it, and searchMode narrows it to one strategy when you want only that one:

import { Select } from "@cliffy/prompt/select";

const module = await Select.prompt({
  message: "Pick a module",
  search: true,
  searchMode: "fuzzy",
  options: ["command", "prompt", "table", "ansi", "keypress"],
});

Substring matches always rank above fuzzy ones, which rank above typo-tolerant ones, so the closest match stays at the top. The same option is available for autocomplete suggestions on input prompts.

With search enabled, the single-letter navigation keys (j, k, n, p) are typed into the search input rather than moving the selection. ctrl+n and ctrl+p now move the highlight through the filtered list without leaving the input, alongside the arrow keys.

Input prompts now understand the editing keys a shell gives you. alt+left and alt+right, or ctrl+left and ctrl+right, move a word at a time. ctrl+w and alt+backspace delete the word behind the cursor, and alt+d the word ahead of it. Useful when a prompt collects something long, like a path or a URL, and it applies to the search input of select and checkbox prompts too.

Those are defaults rather than fixed bindings. The keys option rebinds any of them:

import { Input } from "@cliffy/prompt/input";

const path = await Input.prompt({
  message: "Path",
  keys: { moveWordLeft: ["alt+b"], moveWordRight: ["alt+f"] },
});

Autocomplete prompts can accept whatever is currently highlighted when you press enter, instead of requiring a separate tab first:

import { Input } from "@cliffy/prompt/input";

const branch = await Input.prompt({
  message: "Branch",
  suggestions: ["main", "develop", "release"],
  completeOnSubmit: true,
});

Error handlers now inherit from every ancestor command, not just the immediate parent, so a handler registered on the root command catches errors thrown deep in a subcommand tree.

Shipped in the patch since 1.1.0:

• The upgrade command respects minimum-dependency-age and min-release-age.
• h and l are treated as search input when a prompt has search enabled, rather than as vim navigation keys.
• A type error with Deno 2.8 and newer, caused by the return type of setInterval in the upgrade command's spinner, is fixed. It only showed up for anyone type checking their dependencies, with deno check --all or deno run --check=all.
