Re^2: Prompting for input inside IDE run (was Reading from STDIN)

With mode-compile, which is not core, but nevertheless the default in cperl-mode.

You may want to look into the perl menu in the top-bar after activating cperl-mode.

<menu-bar> <Perl> <Run> runs the command mode-compile, which is an
interactive autoloaded compiled Lisp function in `mode-compile.el'.

Auto flush was helpful yes, but input is still ignored.

Actually all input is considered compilation or error navigation commands, which makes sense in a buffer with start

Now I'm thinking about making my script automatically redirecting stdout and stdin to a spawned console /or buffer. This while still keeping stder in the compilation buffer...

I did this before in order to debug Term::ReadLine apps, have to dig that out again. I'm weak on tty Channel foo ...

With mode-compile, which is no not core but the default in cperl-mode. That would have been helpful to know. That entry is disabled in my Emacs because I don't have mode-compile. Heck, that thing is pretty stale and can't be byte-compiled nor `M-x eval-buffer`ed in Emacs 27... Anyway, `mode-compile` is the culprit. Contrary to its name, it runs the program, using a mechanism which does not make STDIN of the Perl process available to you. What you could do is wrap the following lisp snippet into a command which suits you: `(compile "perl your_script.pl" t)` Replacing the program name `perl` and script name `your_script.pl` by variables is left as an exercise to the reader. The `t` parameter does the trick to give you what Emacs calls a "comint" environment. So, you end up in a buffer `compilation` in compilation-mode with "clickable" error messages, but the buffer is not read-only, you can just enter text after the prompt.	[reply] [d/l]

> (compile "perl your_script.pl" t) Yes, thanks, I already figured this out in the meantime. > variables is left as an exercise to the reader. That's one of the things mode-compile does for me (and is expected from an IDE nowadays) I will try to find a way to patch/configure mode-compile accordingly.
