On: Expect – Writing a Tcl Extension in Only Seven Years (1997)

[zem]

is expect still the default tool for command line automation, or has it been superseded by something else?

[zaphar → zem]

I haven't seen anything else in use anywhere. I believe it's still pretty much the undisputed king.

[cafard → zaphar]

Perl has the work-alike Expect module.

[bjg → cafard]

Python has one as well: https://pexpect.readthedocs.org/en/latest/

[robmil → bjg]

…and Ruby has the PTY module which includes an `expect` method, which is in the same ballpark:

I have found that simply opening sockets , pipes or serial ports and "fconfigure -translation binary -blocking 0 -buffering none" and using event driven I/O in regular Tcl to be superior. You use this same pattern for all activity, which makes things more consistent.
