-# Get the file name in any numbered series of text files and open with emacs
-
-# Usage:
-#     $ . next [descriptor]
-
-# Handles an optional string descriptor. Like this:
-#    $ ls
-#    011.blah.md
-#    $ . next foo
-#    012.foo.md
-
-# File format:
-# in regex terms:
-#   [0-9]+\.[.*\.]*md|txt
-# in plain terms:
-#   [leadings numbers with consistent width].[optional string descriptor and . separator][md|txt]
-
-# what this does:
-# ls | grep [regex for number.*.md] | get last | awk script to increment the digits, preserve the zero prefix, add string descriptor if supplied, and add back extension
-
-# Note the egrep '^\d.*\.md|txt' (matches whole string) to account for an optional string between the initial number and the file extension. As in '435.blah.md'.
-
-# old version, relied on python, which didn't handle leading zeros properly, but treated them as binary:
-# ls | grep '\d.*\.md' | tail -n 1 | sed s/'\..*md'// | sed s/.*/'print & + 1'/ | python - | sed s/.*/'&.md/'
-
-# BUGS
-
-# 1. Emacs won't accept piped input as a file name. I'd rather keep this as a separate utility, which only printed the right filename, and then use an alias to pipe the filename to emacs, or invoke it manually.
-
-# A.
-# What I want, is this syntax:
-# next [optional arg]
-# To both get the file and open emacs with it.
-
-# B.
-# But this doesn't work:
-# next | emacs
-# Because it sees the stdin the pipe wants to feed it as a substitute for the tty in the new session, rather than as input for startup only, i.e. the filename.
-
-# C.
-# Wrapping the whole shell command here works, like this:
-# emacs `ls | grep ...`
-
-# But emacs doesn't like being run inside a child level shell, because it can't load .emacs properly. So you must run this file within the current shell using ".", like this:
-# . next
-# . next foo
-
-# D.
-# This does not work, because .profile must be executed, meaning that the "" expression is peeked by the shell:
-# alias next="emacs `next.sh $1`"
-
-# E.
-# This does not work either, because the arg never gets filled out when evoked:
-# alias next='emacs `next.sh $1`'
-
-# F.
-# This works and is the current solution:
-# alias next='. next.sh'
-
-# Which relies on 2 somewhat obscured facts:
-# 1. This script calls emacs itself, wrapping the real work in ``
-# 2. The alias is a simple substitution, which fortunately seems to happen before args are processed by the shell, meaning that the shell sees: ". next.sh arg"
-# 3. NOTE: the symbolic link in the PATH should not be simply "next", because it
-# may in certain situations conflict with the alias. The link should be "next.sh" -> ~/config/..
-# 4. NOTE: I use 'e' rather than 'emacs', to use my clever emacs/emacsclient function.
