what would be a better way of doing that? i am not disagreeing, but i just can't think of any way to improve on this. put everything into the query part? i prefer to use the query only for optional arguments. in this example the blob argument is the only thing that doesn't fit in my opinion.
Every object in git (commit, tree, revision of a single file) has a hash that is guaranteed unique within a repository (otherwise many more things than a web UI would break) and likely also globally. I can understand wanting to isolate repositories to prevent hash collisions from causing problems, but within a repo everything has a universally unique ID.
edit: for instance, that specific VERBS.md is represented by the blob 3b9a46854589abb305ea33360f6f6d8634649108.

Except it's not, because the oid can be a short hash (https://github.com/gritzko/beagle/blob/a7e172/VERBS.md) and that means you're at risk of colliding with every other top-level entry in the repository, so you're restricting the naming of those toplevel entries, for no reason.
So namespacing git object lookups is perfectly sensible, and doing so with the type you're looking for (rather than e.g. `git` to indicate traversal of the git db) probably simplifies routing, and to the extent that it is any use makes the destination clearer for people reading the link.
turns out that "blob", "raw" and "commit" have nothing to do with the hash itself, but are functions to describe how the object in question is to be presented. so what i said above about blob being redundant is false, the problem is rather that it is in a weird place. it should be at the end, like a kind of extension because it signifies the format of the output. except i think putting it at the end makes handling relative paths more difficult as it would have to be appended to every link to other files.
the roxen webserver has an interesting solution for that. they call it prestates and it's placed at the beginning of a url: https://github.com/(commit)/gritzko/beagle/a7e172/VERBS.md . it sets the format value visually apart, and you could have multiple prestate values separated by a comma. i have used that feature extensively on my own sites. i even expanded on the concept in custom modules.
They are following the /key/value/key/value pattern, but the first two pairs in a GitHub URL are fixed to user and project, which lets them omit the key names. I could see them not being willing to hardcode the third pair to blob.
Back when GitHub URLs were kind of cool, github.com/user/gritzko/project/beagle would have been much less cool than just github.com/gritzko/beagle.
