Hello,
I am only a Chinese student.And my English is lame.
So sorry for my lame English,at first.
I found a mistake in rfc2812.I think you could fix this.
At the page 5 of the protocol,
=======<quotation>======================================
"The presence of a prefix is indicated with a single leading ASCII
colon character (':', 0x3b),....."
======================================================================
The code of the letter ':' is 0x3a.It is not 0x3b.And the code 0x3b is
the letter ';'.
And you could find the same mistake in rfc2813 what is the next
version of the protocol.
I do feel you should fix this mistake.
And I have a question of the protocol rfc2812.
At the page 5 of rfc2812,
In "2.3.1 Message format in Augmented BNF".
I couldn't understand what's the meaning of "*".
=======<quotation>======================================
The Augmented BNF representation for this is:
message = [ ":" prefix SPACE ] command [ params ] crlf
prefix = servername / ( nickname [ [ "!" user ] "@" host ] )
command = 1*letter / 3digit
params = *14( SPACE middle ) [ SPACE ":" trailing ]
=/ 14( SPACE middle ) [ SPACE [ ":" ] trailing ]
nospcrlfcl = %x01-09 / %x0B-0C / %x0E-1F / %x21-39 / %x3B-FF
; any octet except NUL, CR, LF, " " and ":"
middle = nospcrlfcl *( ":" / nospcrlfcl )
trailing = *( ":" / " " / nospcrlfcl )
SPACE = %x20 ; space character
crlf = %x0D %x0A ; "carriage return" "linefeed"
======================================================================
I think it is different between the "*" in "command" and the "*" in "middle".
I do feel you should get some explanation of the "*","()","[]",and so on or
show us where can we find the explantion.
That is what I want to tell you.Wait for you answer.
Yours.
Huang Xiangkui,a student from China.
