bool "Command line history"

default n
|

---help---
|
|
Build in support for Unix-style command history using up and down
|
|
arrow keys. This feature was originally provided by Nghia Ho.
|
|
|
|
NOTE: Command line history is kept in an in-memory array and is
|
|
shared. In the FLAT or PROTECTED builds, this history is shared by
|
|
all threads; in the KERNEL build, the command line history is shared
|
|
by all threads in the process. This means that in a FLAT build, for
|
|
example, a built-in application started from NSH will have the same
|
|
history as does NSH if it also uses readline(). This also means
|
|
that different NSH sessions on serial, USB, or Telnet will also
|
|
share the same history array.
|
|
|
|
In a KERNEL build, each process will have a separately allocated
|
|
history array so the issue is lessened. History would still be
|
|
shared amount pthreads within the same process, however.
