+# snippet-cli
+
+A small in-process snippet manager. No external dependencies; Node.js standard
+library only.
+
+## Contract
+
+`src/cli.js` is CommonJS and exports `run(argv, state)`:
+
+- `argv`: array of command-line words (already split, no program name).
+- `state`: any plain object, created by the caller as `{}`. The CLI keeps its
+  data in it and mutates it in place; it survives across calls.
+- Returns synchronously: `{ code, stdout, stderr }` — a number and two strings
+  (empty string when there is nothing to print). `run` must **never throw**,
+  on any input.
+- All printed lines end with `\n`.
+
+## Commands (all behavior below is contractual)
+
+1. `add <name> [--tags a,b] <text...>` — creates a snippet from the remaining
+   words joined by single spaces. Prints `created <name>`, code 0.
+2. Adding an existing name: code 1, stderr `error: snippet '<name>' already exists`,
+   state unchanged.
+3. `add` with a missing name or missing text: code 2, stderr
+   `usage: add <name> [--tags t1,t2] <text...>`.
+4. Names must match `^[a-z0-9][a-z0-9-]*$`; otherwise code 2, stderr
+   `error: invalid snippet name '<name>'`.
+5. `get <name>` — prints the exact text, code 0. Unknown name: code 2, stderr
+   `error: no snippet named '<name>'`.
+6. `remove <name>` — prints `removed <name>`, code 0. Unknown name: same as `get`.
+7. `list` — every snippet name, sorted ascending, one per line. With no
+   snippets: prints `no snippets`. Always code 0.
+8. `list --tag <t>` — only snippets whose tags include `t`.
+9. `search <term>` — case-insensitive substring match over name **and** text;
+   prints matching names sorted, one per line; prints `no matches` when empty.
+   Code 0.
+10. `export` — prints `JSON.stringify` of `{ snippets: { <name>: { text, tags } } }`
+    with names sorted and each `tags` array sorted. Code 0.
+11. `import <json>` — merges an exported document: names not already present
+    are added, existing names are skipped. Prints `imported <N>, skipped <M>`,
+    code 0. Malformed JSON: code 1, stderr `error: invalid JSON`, state
+    unchanged.
+12. No command or an unknown command: code 2, stderr
+    `usage: snippet <add|get|list|remove|search|export|import>`.
+
+Run the tests with `npm test`.
