1.11 Entering and Exiting

Hemlock is entered by using the COMMON LISP ed function. Simply typing (ed) will enter Hemlock, leaving you in the state that you were in when you left it. If Hemlock has never been entered before then the current buffer will be Main. The -edit command-line switch may also be used to enter Hemlock: see page edit-switch.

ed may optionally be given a file name or a symbol argument. Typing (ed filename) will cause the specified file to be read into Hemlock, as though by Find File. Typing (ed symbol) will pretty-print the definition of the symbol into a buffer whose name is obtained by adding "Edit " to the beginning of the symbol’s name.

Command: Exit Hemlock (bound to C-c, C-x C-z) ¶

Command: Pause Hemlock ¶

Exit Hemlock exits Hemlock, returning t. Exit Hemlock does not by default save modified buffers, or do anything else that you might think it should do; it simply exits. At any time after exiting you may reenter by typing (ed) to LISP without losing anything. Before you quit from LISP using (quit), you should save any modified files that you want to be saved.

Pause Hemlock is similar, but it suspends the LISP process and returns control to the shell. When the process is resumed, it will still be running Hemlock.
