set lastlog_level

Synopsis

/set lastlog_level [<levels>]
/set -lastlog_level

Default: all. With no value, set displays the current mask. Use none or /set -lastlog_level to clear it.

Description

Selects the output levels marked as visible, counted records when new output enters a window's lastlog. Any combination can be selected. These records are available to the lastlog command and count toward the window's lastlog retention limit.

Changing this setting updates the current window's lastlog mask and the global default copied by new windows. It does not update every existing window. Use window lastlog_level for an individual window without changing the global default.

Previously stored entries retain the visibility assigned when they were recorded. A mask change does not retroactively hide, expose, or delete those entries. Output outside the mask can still be stored internally for display reconstruction, so none is not a guarantee that no message text remains in memory. It does not suppress live display or file logging.

Level syntax

Separate names with commas or spaces. Names are case-insensitive. Each assignment starts with an empty mask; it does not incrementally edit the previous value.

• all selects all levels.
• none or -all clears the mask being constructed.
• A leading - removes an individual level, as in all,-opnotes,-snotes.

The parser accepts prefixes for both inclusion and exclusion and takes the first matching level name; ambiguous abbreviations are not diagnosed as such. Prefer full names. Unsupported names produce a warning and list valid levels, while recognized parts still apply. The stored setting is normalized to the resulting mask.

Current built-in names include other (also crap), publics, msgs, notices, walls, wallops, opnotes, snotes, actions, ctcps, invites, joins, nicks, topics, parts, quits, kicks, modes, operwall, syserr, and user1 through user10. A level name's presence does not imply a corresponding protocol event still exists; for example, the old wall hook is removed. Historical dcc and notes levels are not registered here.

Scripts can add levels and aliases through levelctl; use levelctl(levels) or the unsupported-level diagnostic to inspect the available names. Changing this setting sends no IRC request.

Example

Count all new output except server and operator notices in the current window and future windows:

/set lastlog_level all,-opnotes,-snotes

This does not erase previously recorded notice entries. To exclude all levels from the visible count for future entries, use /set lastlog_level none.

• source/window.c: new windows copy the global mask; per-window mask assignment does not retag old entries.
