show a summary of changes after updating environment about emacs-direnv

[christianromney]

Can't wait for the faces enhancement to hit MELPA!

good idea. how would this work with automatic updates via the minor mode?

[wbolster]

i noticed that you deprecated projectile-direnv. existing users of that one should not have any steps back when switching to this one.

i will add this feature, it makes a lot of sense. :)

stay tuned.

i implemented this in 95cd08b.

please try it out, and have a look at the updated readme.

feedback and ideas welcome!

i have added nice colour support for the summary message, which is just so awesome that it is enabled by default. mandatory screenshot:

/cc @christianromney any other features or behaviours from projectile-direnv that do not have an alternative that is at least as good in this package?

[christianromney]

@wbolster This looks great. For some reason direnv--installed isn't being set for me.
When I manually run (executable-find "direnv") it returns the correct path "/usr/local/bin/direnv", but it's not set when I start emacs. If I explicitly setq it in my config, everything works perfectly. Great work!

@christianromney thanks for the kind words.

re. your intitlalisation issue: how do you start emacs? do you change exec-path upon startup, e.g. via exec-path-from-shell?

can you try to add

(message "%s" exec-path)

at the top of your init.el, and also right before you load direnv, i.e. right above (direnv-mode) (if you use that and rely on the autoload). do those paths contain /usr/local/bin/?

manually setting direnv--installed is a hack (it's an internal variable after all).

the reason for the check is that not having direnv installed gives ugly errors in the post-command-hook that direnv-mode installs. i will add a warning when direnv-mode is enabled but direnv could not be found.

@christianromney fyi, in dd0b8c0 i added "detect again" logic when enabling direnv-mode and when direnv was not detected before. does that help?
