通常,在学习语言时,我会编写某种服务器.gforth是否有能力使用网络套接字?
虽然我没有看到任何关于它的文档,但有一个socket.fs绑定到libc.
在GNU FDL下提供,来自IanOsgood的Rossetta代码(提交)
include unix/socket.fs
128 constant size
: (echo) ( sock buf -- sock buf )
begin
cr ." waiting..."
2dup 2dup size read-socket nip

while

rot write-socket
repeat
drop drop drop ;
create buf size allot
: echo-server ( port -- )
cr ." Listening on " dup .
create-server
dup 4 listen
begin
dup accept-socket
cr ." Connection!"
buf ['] (echo) catch
cr ." Disconnected (" . ." )"
drop close-socket
again ;
