I think the point of the linked page is to show how to implement a command line app in Haskell. Teleport is just an example, as such it doesn't really have to be a great tool for everyday usage. On the other hand, teleport seems to actually provide a much better UX than pushd/popd: 1. it's a hash-table not a stack (directories are named), so it allows random access to memorized directories. 2. it is possible to display the current state. 3. remembered directories are persistent between shell sessions.

Naming directories seems like an odd choice. Sounds like aliases? Regardless, pushd/popd/dirs is a tough experience. Seems capable of a lot, but I only use it for bouncing between two directories, typically. The tool I like, but can't remember the name of is basically 'cd ${PWD:src/tst}'. Only, a little more terse. Haven't used it in a while either, since I've primarily switched to eshell.

  Naming directories seems like an odd choice. Sounds like aliases? I definitely use aliases for multiple frequently accessed directories. `kdev` takes me to my work dev folder, `wpdev` takes me to my wordpress folder, etc. But I definitely see the points parent comment to yours made.

    Yeah, I was not intending my post as a counter. Just more discussion.

  what advantage does `eshell` have? And yes, the primary goal of writing this was to have a small CLI app in Haskell, but I've found that I use teleport a decent amount now to quickly zip between common folders

    Main eshell advantage is tramp integration. I can "cd /computer:" to change my directory to remote machine. From there, I can open a file as though it were local. Grep opens results in a buffer that acts as an index to the results. And my magit shortcut acts correctly. Meant to clarify, I was not defending pushd/popd. It is a tough experience. Not a tough experience to beat. And pedagogical is a perfectly fine motivation.
