[PATCH v8 0/3] notmuch-search: Structured Output Formatters

[craven at gmx.net]

From: <craven at 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 at 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 at 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.
