This should cover most of the remaining linting errors. After this, I expect fewer than ten linting errors.

;;; vterm-mgt.el --- Help me manage my vterm instances -*- lexical-binding: t -*-

;; Version: 0.0.1

;; URL: https://git.wpcarro.dev/wpcarro/briefcase

|
;; Package-Requires: ((emacs "25.1"))

|
|
|
;;; Commentary:
|
|
;; Supporting functions to instantiate vterm buffers, kill existing vterm
|
|
;; buffers, rename vterm buffers, cycle forwards and backwards through vterm
|
|
;; buffers.
|
|
;;
|
|
;; Many of the functions defined herein are intended to be bound to
|
|
;; `vterm-mode-map'. Some assertions are made to guard against calling
|
|
;; functions that are intended to be called from outside of a vterm buffer.
|
|
;; These assertions shouldn't error when the functions are bound to
|
|
;; `vterm-mode-map'. If for some reason, you'd like to bind these functions to
|
|
;; a separate keymap, caveat emptor.
