;;; ssh.el --- When working remotely -*- lexical-binding: t -*-

;;; Commentary:
;; Configuration to make remote work easier.

;; TODO: Is "ssh" preferable to "scp"?
(setq tramp-default-method "ssh")
;; Taken from: https://superuser.com/questions/179313/tramp-waiting-for-prompts-from-remote-shell
(setq tramp-shell-prompt-pattern "^[^$>\n]*[#$%>] *\\(\[[0-9;]*[a-zA-Z] *\\)*")
;; Sets the value of the TERM variable to "dumb" when logging into the remote
;; host. This allows me to check for the value of "dumb" in my shell's init file
;; and control the startup accordingly. You can see in the (shamefully large)
;; commit, 0b4ef0e, that I added a check like this to my ~/.zshrc. I've since
;; switched from z-shell to fish. I don't currently have this check in
;; config.fish, but I may need to add it one day soon.
(setq tramp-terminal-type "dumb")
;; Maximizes the tramp debugging noisiness while I'm still learning about tramp.
(setq tramp-verbose 10)
;; As confusing as this may seem, this forces Tramp to use *my* .ssh/config
;; options, which enable ControlMaster. In other words, disabling this actually
;; enables ControlMaster.
