Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Reproduce the error:
(setq eshell-cd-on-directory t) ; in-case you have changed the defaults
Invoke eshell and enter the following commands:
$ /usr/local/share/emacs/28.0.50/lisp/eshell
Read error: Is a directory, /usr/local/share/emacs/28.0.50/lisp/eshell
OR
$ mkdir /tmp/eshell
$ /tmp/eshell
Read error: Is a directory, /tmp/eshell/
So where is the problem?
Checking `eshell-interpreter-alist' value:
((eshell-visual-command-p . eshell-exec-visual)
((closure
(t)
(file _args)
(string= (file-name-nondirectory file)
"eshell"))
. eshell/source)
(#f(compiled-function
(file args)
#<bytecode -0x47e9576cc9960d2>)
. eshell-dirs-substitute-cd))
We can see eshell is using `file-name-nondirectory' to source file which
leads to the read error. I suggest to add one more check before
loading file from `eshell/source'. One example of such check is
`file-regular-p' check and hence I drafted this patch.
