Getting ansi-term(?) to do something via elisp

Getting ansi-term(?) to do something via elisp

[Gary]

I am trying to "script" part of connecting to a remote server as part of
a mode I am working on. What I've discovered is that the remote server
seems to be sending colour control sequences as part of the output, so a
normal shell looks "strange". Is there any alternative to using
something like

,----
| (let ((mypass (read-passwd "Login password for user@server: "
|               )
|      ))
|   (start-process-shell-command foo
|                                "foo"
|                                "ssh bar@foo")
|   (process-send-string foo (concat mypass "\n"))
| ...
`----

perhaps using ansi-term, which can handle the control sequences?

I thought of just trying to send the commands that I need ("ssh" and so
on) to an ansi-term buffer, but don't know how to get hold of the
process.

Do an apropos for 'ansi-color'. You will find a number of functions and
variables used to process ansi colour escape sequences from comint
buffers. Should be able to setup soemthing using the process output
filter that will handle these escape sequences.

Too late ;) but thanks anyway :)

I found get-buffer-process and am using that on an ansi-term buffer I
create for the purpose, which seems to work adequately for what I want.
