# E-scripts on eshell.
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
# (find-eev-quick-intro)
# http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the

# Subj: Examples of usage of Eshell (for a tutorial)?
Hi all,
first of all, apologies if this sounds like a lazy question... it's
for a good cause, I swear! =)
I would like to write a (sort of) mini-tutorial on Eshell that would
be made mostly of examples that can be executed with this,
http://angg.twu.net/eepitch.html
with links to docs of all kinds. Here are some examples of other
sort-of-tutorials written in that way:
http://angg.twu.net/e/lua-intro.e.html#intro:PP
http://angg.twu.net/e/python.e.html#tut-numbers
Do you have any snippets, or links to pages with snippets, to suggest?
I know the info manual of Eshell and I've tried to read it several
times, but most of the features that it describes are "example-less" -
I've tried to write snippets that demonstrate them, but failed or gave
up...
Thanks in advance!

eshell/wget: a minimalistic wget for eshell
Hi all (and John Wiegley),
I wrote a function eshell/wget - or eshell/fakewget - that uses
url-retrieve-synchronously to download files from the internets.
It is here (and eev is in ELPA):
http://angg.twu.net/eev-current/eev-plinks.el
http://angg.twu.net/eev-current/eev-plinks.el.html#find-urlretrieve
I don't recommend using it for big files because it doesn't output any
progress reports until it finishes. I wrote it for a workshop that
will have several participants who are Windows users who have never
used a terminal in their lives - see this thread:
https://lists.gnu.org/archive/html/help-gnu-emacs/2021-10/msg00037.html
https://lists.gnu.org/archive/html/help-gnu-emacs/2021-10/threads.html#00037
but I think that it may be useful in other situations, too.
I don't know how to advertise it. I looked for an index of
user-written eshell extensions and I only found this:
https://www.emacswiki.org/emacs/EshellExtensions
and I thought that it would be a good idea to announce it here first -
and ask for advice.
Cheers =),
Eduardo Ochs

<wgreenhouse> but I like new ways to converse with emacs. I spend a
lot of time in eshell and in some ways eev feels like
a fellow-traveler of eshell
<edrx> I've tried to learn how to add commands to eshell years ago,
when its documentation was very sparse, and I failed
miserably... if anything doesn't work in eshell please tell
me! also, I only added support for vterm just a few days
ago...

<wgreenhouse> grym: I'll stan for the first 6 Dune books being
worth one's time
<wgreenhouse> after that it is indeed downhill
<edrx> wgreenhouse: did you modify eshell to add your own hacks?
<wgreenhouse> edrx: I mostly use it as-is, but gradually accumulate
some aliases for things that should probably be elisp
functions
<edrx> wgreenhouse: hmm, ok
<edrx> when I tried to hack it I wanted to make it recognize "wget"
as special command and run a lisp function instead of
/usr/bin/wget... but I gave up
<wgreenhouse> edrx: you would need to create an interactive
function named eshell/wget or so, and it should be
picked up as a command
