A simple shell function to allow emacsclients (or emacs) to read from stdin via a temp file.
Tested with zsh, bash and sh. Everything should work with other modern shells (there's nothing fancy going on).
To use emacs rather than emacsclient, or to modify the command line args used, change the _emacsstdin and _emacststdin functions.
Set up by sourcing the file emacs-read-stdin.sh in your .bashrc (or equivalent) with
source /path/to/repo/emacs-read-stdin.sh
or by simply copying and pasting the two functions into .bashrc.
Read from stdin
echo "hello world" | e -
or as normal from files
e hello_world.txt
To read from stdin and open emacs in terminal mode
echo "hello world" | e -t
Run the script run-tests.sh to test the function. Check in the script for the expected output to compare against (I should probably rewrite the tests in python or something so that the checking can be easily automated).
