query_window_reset()

Restore vfolder's search window to its original position.

windowed_query_from_query()

static bool windowed_query_from_query ( const char * query, char * buf, size_t buflen )

static

Transforms a vfolder search query into a windowed one.

Parameters

[in]	query	vfolder search string
[out]	buf	allocated string buffer to receive the modified search query
[in]	buflen	allocated maximum size of the buf string buffer

Return values

true	Transformed search query is available as a string in buf
false	Search query shall not be transformed

Creates a date: search term window from the following user settings:

• nm_query_window_enable (only required for nm_query_window_duration = 0)
• nm_query_window_duration
• nm_query_window_timebase
• nm_query_window_current_position

The window won't be applied:

• If the duration of the search query is set to 0 this function will be disabled unless a user explicitly enables windowed queries.
• If the timebase is invalid, it will show an error message and do nothing.

If there's no search registered in nm_query_window_current_search or this is a new search, it will reset the window and do the search.

get_query_string()

static char * get_query_string ( struct NmMboxData * mdata, bool window )

static

Builds the notmuch vfolder search string.

Parameters

mdata	Notmuch Mailbox data
window	If true enable application of the window on the search string

Return values

ptr	String containing a notmuch search query
NULL	None can be generated

This function parses the internal representation of a search, and returns a search query string ready to be fed to the notmuch API, given the search is valid.

Note

The window parameter here is here to decide contextually whether we want to return a search query with window applied (for the actual search result in mailbox) or not (for the count in the sidebar). It is not aimed at enabling/disabling the feature.
