Presently, there are 15 (!) /SET's that control how stuff to be displayed
gets mangled by the mangler...
DISPLAY_ANSI DISPLAY_PC_CHARACTERS EIGHT_BIT
BEEP BEEP_MAX TAB_MAX
ND_SPACE_MAX INVERSE_VIDEO BOLD_VIDEO
BLINK_VIDEO UNDERLINE_VIDEO ALT_CHARSET
COLOR ALLOW_C1_CHARS TERM_DOES_BRIGHT_BLINK
You all know about the "mangler" sets:
MANGLE_INBOUND
MANGLE_OUTBOUND
MANGLE_LOGFILE
For the purposes of "simplification", I am trying to reduce the number of
historical curiosities in epic5 that support features that extremely few
people actually need, outside of unmitigated curiosity.
I propose to remove most or all of these /set's and add a new one, called
/SET MANGLE_DISPLAY. We know the mangler directly supports 8 of the 15
/set's, among other things:
ANSI /set display_ansi
ND_SPACE /set nd_space_max
REVERSE /set inverse_video
BOLD /set bold_video
BLINK /set blink_video
UNDERLINE /set underline_video
ALT_CHAR /set alt_charset
COLOR /set color
The 7 that are not directly addressed are:
/SET BEEP
/SET ALLOW_C1_CHARS
I think we could add these two as new mangle types.
/SET BEEP_MAX
Once upon a time (over 13 years ago), ircII used to beep at you once
for each ^G. For the last 13 years, ircII will only beep once per
line, no matter how many ^G's there are. While someone could come
up with a contrived reason why keeping this might be useful, it is
expensive and complicated to support this and would be much simpler
to just treat it as though it had the hardcoded value everybody
uses (0 -- no limit). I therefore propose to de-support this.
/SET TAB_MAX
IrcII used to have a hard limit of 2048 bytes (25 screen lines) per
logical line of output. It used to be possible for a privmsg with
over 250 tabs to exceed the 2048 byte line limit and cause overflow.
EPIC has no limitation on logical line size, so this is not an issue
for us. It's the same story as BEEP_MAX -- it's expensive and
complicated. Hardcoding the default value of 0 (no limit) is not
going to cause any real problems. I propose to de-support this.
/SET EIGHT_BIT_CHARACTERS
This set is meant for those whose terminal emulators are incapable
of handling 8 bit data. Such terminal emulators have long since
gone into history, and there is no reason why we can't assume that
the user has an 8 bit capable terminal. EPIC4 will always be around
and supported, and it will always support 7 bit characters, but I
propose that in epic5 we no longer worry about compatability with
8-bit-incapable terminals.
/SET DISPLAY_PC_CHARACTERS
This is used to handle converting 8 bit characters to 7 bit
equivalents for people who don't have 8 bit characters. For the
same reasons as above, this is a feature that I think should be
retired.
/SET TERM_DOES_BRIGHT_BLINK
I'm not sure what this does, so I'll keep it. I know that knghtbrd
says it's very important!
