Broken Formatting When Running in SLIME/SLY

[artforlife]

When I run Prove tests in SLIME using the ASDF integration, I get the following formatting:

�[32m✓ 0 tests completed�[0m �[90m(0ms)�[0m

Running a test file '/Users/xxx/xxx/cl-mongo-json.lisp'
1..3

�[32m✓ �[90mT is expected to be T�[0m
�[0m
�[32m✓ �[90m4 is expected to be 4�[0m
�[0m
�[32m✓ �[90m1 is not expected to be #\1�[0m
�[0m
�[32m✓ 3 tests completed�[0m �[90m(0ms)�[0m

Summary:
All 2 files passed.

The strange characters are actually ^[.

Am I doing something wrong or is this a bug?

Hello

Those are ansi color settings, for use in a terminal (or slime with an extension, see link below).

try setting

(setf prove:*enable-colors* nil)

it's suprising it is on by default, it's off for me.

I believe this fixed it. How can I make sure this is always done for this system? Should this be placed into the first test file or ASDF declaration?

eheh, awesome^^ It's nice that as a newcomer you find helping hands :)

Not sure where best to put the setting to always disable it (sbclrc ?). Is is the same with (prove:run… ?
On the contrary, you can also always load slime-repl-ansi-on.el to have nice colors.

;; .emacs.d/init.el
  (defvar my-elisp-files '(
                           "~/.emacs.d//vendor/slime-repl-ansi-color.el"
    )
    (dolist (lib my-elisp-files)
    (if (file-exists-p lib)
        (load-file lib)))
