less --file-size (Windows)

[adoxa]

less --file-size FILE leaves behind the length message.

C:\Projects\less>less --file-size less.man
Determining length of file... (interrupt to abort)
C:\Projects\less>

I tried adding ierror("", NULL_PARG), but that still leaves the abort part. Could just use clear_bot(), but that leaves need_clr set (not that it matters too much, I guess).

I'm confused -- on Linux at least, ierror sets need_clr which causes putchr to call clear_bot. The clear_bot erases the Determining message. I would expect this all to work the same on Windows, so I don't understand why you are seeing the message. If I run with termcap debug on I see

$ echo hello | LESS_TERMCAP_DEBUG=1 less --file-size 
<cr><cd><so>Determining length of file... (interrupt to abort)<se><cr><cd><ti><ks><cr>hello
<so>(END)<se><ce>

The "<cr><cd>" after the message represents a call to clear_bot.

Don't compare Windows & Linux. ;) It would seem this message (and the "binary" one) are displayed before the console switches screens. I don't think that can be done earlier because of -F (but even so it probably wouldn't be right for the "binary" one).

Yes, the Determining message is displayed before switching screens, but the clear_bot should also happen before switching screens. Ah, perhaps the difference is Linux uses putchr to send the init ("ti") sequence, which invokes clear_bot, but Windows doesn't call putchr anywhere in init(). Maybe the need_clr/clear_bot check that's in putchr should be done explicitly at the start of init().

Let me know if 81c1184 fixes this in Windows.

Yep, that got it, thanks.
