(the following text accompanies the patch at <Someone>'s web page)
add more configurability to the new msg_window option of [..]3.4.0.
It allows the configuration option to take an optional parameter to
specify the style of message history display to use.
allows the following configuration options:
msg_window:s - single message (as was the default in 3.3.0)
msg_window:c - combination; two messages in 'single', then as 'full'
msg_window:f - full window; oldest message first
msg_window:r - full window reversed; newest message first
In the event of no parameter being provided,
the patch is compatible with the current 3.4.0 behaviour:
msg_window = 'full'
!msg_window = 'single'
msg_window can be configured for these options in the
Options menu (Shift-O)
msg_window stores the current window type in the non-persistent
iflags structure, which means that savefile/bones files should be
100% compatible with Vanilla, but at the disadvantage that your
customisations to msg_window will be replaced with your
defaults.nh (or ~/.nethackrc) value every time you restart a saved game.
Credits:
The patch draws inspiration (and code snippets) extensively
from <Someone>'s original msg_window patch, [...] as well as <Someone>'s code for reverse ordering implemented until recently in
Slash'em.
- typing ESC would lose messages if msg_window was not displayed
- incorporate <Someone>'s fix, which causes them to be tracked, just not
displayed, and thus still available for ^P viewing later on
- attempt to determine if tty_wait_synch() is called during the ending
dialogs due to an interrupt, and not re-display the previous message
at the wrong time
- also, "msg_window display anomaly" fix was missing code to still treat ^P
properly while in a prompt
If you interrupt nethack (^C) in tty windowport mode while a pompt is
displayed and and msg_window=true, it can display the full message history
at an unexpected time. Detect this and display only the topl, as expected.
