pimalaya/himalaya v0.7.0 on GitHub

Added offline support with the account sync command to synchronize
a backend to a local Maildir backend [#342].
Added the flag --disable-cache to not use the local Maildir
backend.
Added the email composer (from its own
repository) [#341].
Added Musl builds to releases [#356].
Added himalaya man command to generate man page [#419].

Made commands read, attachments, flags, copy, move,
delete accept multiple ids.
Flipped arguments ids and folder for commands copy and move
in order the folder not to be considered as an id.

Removed the -a|--attachment argument from write, reply and
forward commands. Instead you can attach documents directly from
the template using the syntax <#part filename=/path/to/you/document.ext>.
Removed the -e|--encrypt flag from write, reply and forward
commands. Instead you can encrypt and sign parts directly from the
template using the syntax <#part type=text/plain encrypt=command sign=command>Hello!<#/part>.
Removed the -l|--log-level option, use instead the RUST_LOG
environment variable (see the
wiki)

himalaya-lib `v0.5.0`

Made backend functions accept a vector of id instead of a single id
[#20].
Added function Backend::purge_folder that removes all emails
inside a folder.
Added new Backend functions using the internal id:
- get_envelope_internal: gets an envelope by its internal id
- add_email_internal: adds an email and returns its internal id
- get_emails_internal: gets emails by their internal id
- copy_emails_internal: copies emails by their internal id
- move_emails_internal: copies emails by their internal id
- delete_emails_internal: copies emails by their internal id
- add_flags_internal: adds emails flags by their internal id
- set_flags_internal: set emails flags by their internal id
- remove_flags_internal: removes emails flags by their internal id
Added emails synchronization feature. Backends that implement the
ThreadSafeBackend trait inherit the sync function that
synchronizes all folders and emails with a local Maildir instance.
Added Backend::sync function and link ThreadSafeBackend::sync to
it for the IMAP and the Maildir backends.
Added the ability to URL encode Maildir folders (in order to fix
path collisions, for eg [Gmail]/Sent). Also added a
MaildirBackendBuilder to facilitate the usage of the
url_encoded_folders option.
Added a process lock for ThreadSafeBackend::sync, this way only
one synchronization can be performed at a time (for a same account).

Improved Backend method names. Also replaced the self mut by a
RefCell.
Simplified the Email struct: there is no custom implementation
with custom fields. Now, the Email struct is just a wrapper around
mailparse::ParsedMail.
Improved Flag structures.
Changed Backend trait functions due to [#20]:
- list_envelope => list_envelopes
- search_envelope => search_envelopes
- get_email => get_emails, takes now ids: Vec<&str> and
  returns an Emails structure instead of an Email)
- copy_email => copy_emails, takes now ids: Vec<&str>.
- move_email => move_emails, takes now ids: Vec<&str>.
- delete_email => delete_emails, takes now ids: Vec<&str>.
- add_flags takes now ids: Vec<&str> and flags: &Flags.
- set_flags takes now ids: Vec<&str> and flags: &Flags.
- remove_flags takes now ids: Vec<&str> and flags: &Flags.
