doiget_cli/commands/
mod.rs

1//! Subcommand implementations for the `doiget` CLI.
2//!
3//! Each module corresponds to a single `clap` subcommand declared in
4//! `main.rs`. The dispatch table in `main.rs` calls `run(...)` on the
5//! matching module. Subcommands return `anyhow::Result<()>`; any error
6//! surfaces via the CLI's top-level error reporter (stderr).
7//!
8//! ## Phase 1 surface (so far)
9//!
10//! - [`audit_log`] — `doiget audit-log --verify` recomputes the SHA-256 hash
11//!   chain on the provenance log and reports any mismatches.
12//! - [`batch`] — `doiget batch <path>` multi-ref orchestrator (rate-bounded).
13//! - [`bib`] — `doiget bib <ref>` BibTeX exporter (Phase 2 starter).
14//! - [`cite`] — `doiget cite <ref>` live-resolve BibTeX (doi2bib-style).
15//! - [`config`] — `doiget config show/path/doctor`.
16//! - [`csl`] — `doiget csl <ref>` exports a stored entry as CSL JSON 1.0.
17//! - [`fetch`] — `doiget fetch <ref>` orchestrator (arXiv E2E + DOI metadata-only).
18//! - [`info`] — prints a stored entry's `Metadata` as TOML on stdout.
19//! - [`list_recent`] — prints up to N most-recently-fetched entries.
20//! - [`search`] — case-insensitive substring search over stored metadata.
21//!
22//! Other subcommands (`serve`) land in separate PRs.

52/// Resolution order (subset of `docs/CONFIG.md` §4 — full CLI-flag /
53/// config-file resolution lands with the `config` subcommand):
54///
55/// 1. `DOIGET_STORE_ROOT` environment variable, if set and non-empty.
56/// 2. Fallback to `$HOME/papers` (POSIX) or `%USERPROFILE%\papers` (Windows).
57///
58/// The env-var hook is sufficient for both real use and integration tests
59/// — tests set `DOIGET_STORE_ROOT` to a `tempfile::TempDir` to keep the
60/// real `~/papers/` untouched.
