Every time I had to build exa, I copied the files manually and checked to make sure they all had the same name. There’s now a script that does all that stuff for me, so I don’t need to remember to do it anymore.
It also does some things that weren’t being done before, including stripping the binary and listing its linked dependencies to we can tell if something like libhttp_parser has slipped in there (see #194)
The non-contrib Debian one doesn’t come with guest additions, meaning it used rsync instead of Virtualbox shared folders to sync files, meaning edits made in the VM didn’t get propogated back to the host, meaning I got very confused for a while.
Thanks to the parent commit, this shouldn’t be an issue at all: the default user name, which is now “ubuntu” instead of “vagrant” is specified in a lot fewer places, making it much easier to change.
See the README section for more details. Basically, with this way, we can store a bunch of existing valid exa outputs, change a VM's environment to match our values, then check that exa still works by comparing outputs.
