Compilation of context.lisp fails, formatter error

[IGJoshua]

When attempting to install trial (on windows, might be relevant) for testing (using the form (ql:quickload 'trial)) I found that it gives me an interesting error suggesting the the use of format in the function context-info in context.lisp is somehow malformed. Since I'm somewhat new to common lisp I'm unsure of the specific nature of this error and google was unhelpful. Is this something wrong with the latest version of trial, or am I simply missing something?

My current solution is to simply replace the formats that error with one that simply states where it is, and that it is failing. This has led me to find similar issues in the tick handler on controllers in controller.lisp.

After finishing getting this to install properly it has also revealed that I'm unsure how to get a backend working in trial. I tried to add it to my asdf list and install it but it gave me issues when trying to load it as well.

Sounds to me like you have your git settings screwed up in such a way that it changed line endings to the Windows CRLF, rather than the unix LF.

Alright, thanks. I'll see if I can fix that (or just get it to run under linux)
