Miniexpect is a very simple expect-like library

Expect (https://core.tcl-lang.org/expect/index) is a venerable Tcl program for automating interactive services, often for automating logins over telnet, ftp, ssh, etc.

Miniexpect is a C library which has a saner interface than libexpect, and doesn't depend on Tcl. It is also thread safe, const-correct and uses modern C standards.

Miniexpect is standalone, except that it requires the PCRE2 (Perl Compatible Regular Expressions) library from http://www.pcre.org/. The PCRE2 dependency is fundamental because we want to offer the most powerful regular expression syntax to match on, but more importantly because PCRE2 has a convenient way to detect partial matches which made miniexpect very simple to implement.

The library was written by Richard W.M. Jones rjones@redhat.com and is licensed under the Library GPL (LGPL) version 2 or above.

Source is available from: http://git.annexia.org/?p=miniexpect.git;a=summary

If you wanted to copy the library into your own code (instead of linking to it as a dependency), you only need to copy the two files: miniexpect.h, miniexpect.c.

The API is documented in the manual page (miniexpect.pod / miniexpect.3).

For examples of how to use the API in reality, see the examples and tests in the source directory.
