From: <craven@gmx.net> Currently there is no easy way to add support for different structured formatters (like JSON). For example, adding support for S-Expressions would result in code duplication. This patch series amends the situation by introducing structured formatters, which allow different implementations of structures like lists, maps, strings and numbers. The new code in sprinter.h and sprinter-json.c can be used instead of the current ad-hoc output in all parts of notmuch, a patch for notmuch-search.c is included. In a later patch, all other parts of notmuch should be adapted to the structured formatters, and the creation of formatters should be centralised (to make adding new formatters easier). A "structured" formatter is provided for notmuch-search that prints the current text format. This removes almost all the special-casing from notmuch-search.c. Changes versus v7 of this patch: - added {} around "else" blocks (as mentioned in id:20120722160843.GC31834@mit.edu) - added fallback to INTERNAL_ERROR (which should never be called) in notmuch-search.c if format is unknown (as mentioned in id:m2r4s694ly.fsf@guru.guru-group.fi). Summary: Peter Feigl (3): Add support for structured output formatters. Add structured output formatter for JSON and plain text (but don't use them yet). Use the structured formatters in notmuch-search.c.
