Himalaya v2 Email CLI

Use this skill only with Himalaya major version 2. Its command and configuration syntax differs from v1.

References

• references/configuration.md for v2 config paths, accounts, and backends.
• references/message-composition.md for v2 compose and send flows.

Install and configure

Install a v2 build and verify it before continuing:

himalaya --version

Official installation options include Homebrew and the current Git repository:

brew install himalaya
cargo install --locked --git https://github.com/pimalaya/himalaya.git

If the package manager installs v1, use a v2 release or the Git installation. Run the v2 setup wizard with no subcommand:

himalaya

The wizard prints TOML that can be saved or merged into the config. There is no v2 account configure command. Check the result with:

himalaya --json account list
himalaya --account=work account check

Command conventions

Use v2's global account and backend selectors before the subcommand. Mailbox selectors belong to the leaf command:

himalaya --json --account=work --backend=imap envelope list --mailbox=INBOX

• --json selects structured output; v2 does not use --output json.
• --account and --backend are global selectors. --mailbox is a leaf-command option; these can also be written as -a, -b, and -m.
• Shared read backends are imap, jmap, gmail, msgraph, maildir, and m2dir. SMTP sends messages; it does not fetch them.
• Message IDs are mailbox-relative for some backends. Re-list after moving mail or changing mailboxes.

Read operations

List mailboxes and envelopes:

himalaya --json --account=work --backend=imap mailbox list
himalaya --json --account=work --backend=imap \
  envelope list --mailbox=INBOX --page=1 --page-size=20

Search with the v2 shared query language:

himalaya --json --account=work --backend=imap \
  envelope search --mailbox=INBOX -- \
  from [e-mail] and subject meeting order by date desc

Read a rendered message or raw RFC 5322/MIME:

himalaya --account=work --backend=imap message read --mailbox=INBOX -- 42
himalaya --account=work --backend=imap message read --mailbox=INBOX --raw -- 42

The shared envelope search query language is not implemented by the v2 Gmail or Microsoft Graph backends. Use their protocol-specific APIs when native search is required:

himalaya --json --account=work gmail messages list -q "from:alice is:unread"
himalaya --json --account=work msgraph mail-folder list

Manage messages

Use explicit source and destination mailboxes for copy or move operations:

himalaya --account=work --backend=imap message copy --from=INBOX --to=Archives -- 42
himalaya --account=work --backend=imap message move --from=INBOX --to=Archives -- 42

The shared message command in Himalaya v2.0.0 has no delete operation. Use a backend-specific command when deletion is required.

Manage flags and attachments:

himalaya --account=work --backend=imap flag add --mailbox=INBOX --flag=seen -- 42
himalaya --account=work --backend=imap flag remove --mailbox=INBOX --flag=seen -- 42
himalaya --account=work --backend=imap attachment list --mailbox=INBOX -- 42
himalaya --account=work --backend=imap attachment download --mailbox=INBOX -- 42

Debugging

Every command provides v2-specific help. Use logging on stderr when needed:

himalaya envelope search --help
himalaya --log=debug --account=work --backend=imap mailbox list
himalaya --log=trace --log-file=/tmp/himalaya.log \
  --account=work --backend=imap mailbox list
