1 This file describes the schemata used for notmuch's structured output
2 format (currently JSON and S-Expressions).
4 []'s indicate lists. List items can be marked with a '?', meaning
5 they are optional; or a '*', meaning there can be zero or more of that
6 item. {}'s indicate an object that maps from field identifiers to
7 values. An object field marked '?' is optional. |'s indicate
8 alternates (e.g., int|string means something can be an int or a
11 For S-Expression output, lists are printed delimited by () instead of
12 []. Objects are printed as p-lists, i.e. lists where the keys and values
13 are interleaved. Keys are printed as keywords (symbols preceded by a
14 colon), e.g. (:id "123" :time 54321 :from "foobar"). Null is printed as
15 nil, true as t and false as nil.
17 This is version 4 of the structured output format.
23 - First versioned schema release.
24 - Added part.content-length and part.content-transfer-encoding fields.
27 - Added the thread_summary.query field.
30 - Replaced message.filename string with a list of filenames.
31 - Added part.content-disposition field.
34 - replace signature error integer bitmask with a set of flags for
