- * FIXME: At least some of these functions should be replaced with
- * GTK GUI error-box-type things.
+ * TODO:
*
- * In particular, all the termios-type things must go, and
- * termios.h should disappear from the above #include list.
+ * - Remainder of the context menu:
+ *
+ * - Event Log (this means we must implement the Event Log; not
+ * in pterm)
+ *
+ * - New Session and Duplicate Session (perhaps in pterm, in fact?!)
+ * + Duplicate Session will be fun, since we must work out
+ * how to pass the config data through.
+ * + In fact this should be easier on Unix, since fork() is
+ * available so we need not even exec (this also saves us
+ * the trouble of scrabbling around trying to find our own
+ * binary). Possible scenario: respond to Duplicate
+ * Session by forking. Parent continues as before; child
+ * unceremoniously frees all extant resources (backend,
+ * terminal, ldisc, frontend etc) and then _longjmps_ (I
+ * kid you not) back to a point in pt_main() which causes
+ * it to go back round to the point of opening a new
+ * terminal window and a new backend.
+ * + A tricky bit here is how to free everything without
+ * also _destroying_ things - calling GTK to free up
+ * existing widgets is liable to send destroy messages to
+ * the X server, which won't go down too well with the
+ * parent process. exec() is a much cleaner solution to
+ * this bit, but requires us to invent some ghastly IPC as
+ * we did in Windows PuTTY.
+ * + Arrgh! Also, this won't work in pterm since we'll
+ * already have dropped privileges by this point, so we
+ * can't get another pty. Sigh. Looks like exec has to be
+ * the way forward then :-/
+ *
+ * - Saved Sessions submenu (not in pterm of course)
+ *
+ * - Change Settings
+ * + we must also implement mid-session reconfig in pterm.c.
+ * + note this also requires config.c and uxcfg.c to be able
+ * to get hold of the application name.
+ *
+ * - Copy All to Clipboard (for what that's worth)
