Hello,
eshell allows you to modify the output of a command and run it. It is a
beautiful thing.
Example:
$ ls
file.el
$
now go up and append "file" to the output and hit enter.
$ ls
file file.el
$ file file.el
color.el: Lisp/Scheme program, Unicode text, UTF-8 text
$
The ability is currently broken because "file.el" has the field property
set to "command-output" and the "file" command that I added has no
property field. So currently the previous interaction would actually
yield:
$ ls
file file.el
$ file.el
file.el: command not found
$
This was broken in commit 558f04c39e036d2f681f72556627768d7bee9ab5. Now
adding the field to eshell prompt makes a lot of sense and I like that.
I don't know much about fields but it looks like it is not necessary to
have a command-output field at all. I propose we get rid of that. If
you want to keep the field, can we make it sticky or something? I just
want the above usecase fixed.
Thanks,
Morgan

Interesting. I didn't realize this was possible in Eshell (I only
thought you could re-run old *inputs*).

The output field is actually necessary (or else Eshell would need to be
cleverer about some things). The main issue is that if a command doesn't
output a newline, the command's output can end up on the same line as
the prompt:
~ $ *echo -n [output]
[output]~ $
If the output had no field, C-a would move to the very beginning of the
line, not to the beginning of the input field. Maybe this is a bug in
how fields are handled, but changing field handling in general is
probably too risky.
So instead, let's make the output field sticky as you say. Here's a fix
for that plus regression tests so this won't break in the future.

Subject: [PATCH] Ensure that Eshell users can run lines of command output as

Previously, this failed to work properly because any additional input
the user entered would have no 'field' property, confusing
'eshell-get-old-input'. To fix this, we simply ensure that any
user-entered text in the output field retains said output field
(bug#61310).

You might also be interested in how comint deals with this. It can
handle the case when the user yanks something in the middle of output as
well. See function comint--mark-as-output, bug#3735 and bug#18135 for
more details.

Good call. Here's a patch that (mostly) copies those comint functions
