I'm generally in demand of small, quick startup, easy-to-embed languages that aren't Lua (I can't stand Lua; I feel like every time I've had to deal with Lua code was far more painful than reasonably possible). There's mruby and maybe a couple others. I was hoping Pixie might be another contender in that space, but it doesn't seem to be after all (or if it is, it's very poorly documented to that effect).

I've been tinkering with some ideas for another language in that space (the Crafting Interpreters book is looking to be pretty helpful in getting me there: http://www.craftinginterpreters.com/), but it'd be really nice if there were enough options for me to not feel the need to create my own.

A list that I maintain might help you find one: https://github.com/dbohdan/embedded-scripting-languages. Personally, I am a fan of Jim Tcl (http://jim.tcl.tk), especially for when you need a small interpreter that knows how to interact with its Unixy environment (i.e., the file system, processes, sockets and UTF-8 text data) out of the box.

Jim Tcl actually looks about damn perfect. I'll definitely have to give that one a whirl.

In the last, I have been very happy with Gambit Scheme for building small pre-compiled executables for command line utilities, etc. A lot of people use Chichen Scheme for the same purpose.

Picolisp. I found it very easy to embed.
