From: David Bremner <brem...@unb.ca> Currently this only outputs the information from the "message header"; i.e. the part before the rfc2822 header or body.
Adding this required adding an extra parameter, currently unused, to format_message_text and format_message_json. Also the struct definition is changed to match the new function prototypes. An int (enum) is used as a mask, each bit corresponds to some part to be shown or not shown. This enum will need to be extended as more things are controllable via --show. --- notmuch-show.c | 89 ++++++++++++++++++++++++++++++++++++++++++++++++------- 1 files changed, 77 insertions(+), 12 deletions(-) diff --git a/notmuch-show.c b/notmuch-show.c index 51aa87d..99a4d3c 100644 --- a/notmuch-show.c +++ b/notmuch-show.c @@ -20,10 +20,18 @@ #include "notmuch-client.h" +/* These should be powers of 2 */ +typedef enum {SHOW_MESSAGE_ID = 1, + SHOW_MATCH = 2, + SHOW_FILENAME = 4 +} show_mask_t; + +static const show_mask_t SHOW_ALL = ~0; + typedef struct show_format { const char *message_set_start; const char *message_start; - void (*message) (const void *ctx, + void (*message) (const void *ctx, show_mask_t show_mask, notmuch_message_t *message, int indent); const char *header_start; @@ -40,7 +48,7 @@ typedef struct show_format { } show_format_t; static void -format_message_text (unused (const void *ctx), +format_message_text (unused (const void *ctx), show_mask_t show_mask, notmuch_message_t *message, int indent); static void @@ -59,7 +67,21 @@ static const show_format_t format_text = { }; static void -format_message_json (const void *ctx, +format_message_tabular (unused (const void *ctx), show_mask_t show_mask, + notmuch_message_t *message, + int indent); + +static const show_format_t format_tabular = { + "", + "", format_message_tabular, + "", NULL, "", + "", NULL, "", + "\n", "", + "" +}; + +static void +format_message_json (const void *ctx, show_mask_t show_mask, notmuch_message_t *message, unused (int indent)); static void @@ -124,7 +146,30 @@ _get_one_line_summary (const void *ctx, notmuch_message_t *message) } static void -format_message_text (unused (const void *ctx), notmuch_message_t *message, int indent) +format_message_tabular (unused (const void *ctx), show_mask_t show_mask, + notmuch_message_t *message, + unused(int indent)) +{ + int count=0; + + if (show_mask & SHOW_MESSAGE_ID) { + fputs ( notmuch_message_get_message_id (message), stdout); + count++; + } + + if (show_mask & SHOW_MATCH) + printf ("%s%d", count++ ?
