2 * Unix PuTTY main program.
17 * - Fix command-line parsing to be more PuTTYlike and not so
18 * ptermy - in particular non-option arguments should be
19 * hostname and port in the obvious way.
21 * - libcharset enumeration.
23 * - fix the printer enum (I think the sensible thing is simply to
24 * have uxcfg.c remove the drop-down list completely, since you
25 * can't sensibly provide an enumerated list of lpr commands!).
27 * - Ctrl+right-click for a context menu (also in Windows for
28 * consistency, I think). This should contain pretty much
29 * everything in the Windows PuTTY menu, and a subset of that in
32 * - Telnet special commands (not in pterm :-)
34 * - Event Log (this means we must implement the Event Log; not
37 * - New Session and Duplicate Session (perhaps in pterm, in fact?!)
38 * + Duplicate Session will be fun, since we must work out
39 * how to pass the config data through.
40 * + In fact this should be easier on Unix, since fork() is
41 * available so we need not even exec (this also saves us
42 * the trouble of scrabbling around trying to find our own
43 * binary). Possible scenario: respond to Duplicate
44 * Session by forking. Parent continues as before; child
45 * unceremoniously frees all extant resources (backend,
46 * terminal, ldisc, frontend etc) and then _longjmps_ (I
47 * kid you not) back to a point in pt_main() which causes
48 * it to go back round to the point of opening a new
49 * terminal window and a new backend.
50 * + A tricky bit here is how to free everything without
51 * also _destroying_ things - calling GTK to free up
52 * existing widgets is liable to send destroy messages to
53 * the X server, which won't go down too well with the
54 * parent process. exec() is a much cleaner solution to
55 * this bit, but requires us to invent some ghastly IPC as
56 * we did in Windows PuTTY.
57 * + Arrgh! Also, this won't work in pterm since we'll
58 * already have dropped privileges by this point, so we
59 * can't get another pty. Sigh. Looks like exec has to be
60 * the way forward then :-/
62 * - Saved Sessions submenu (not in pterm of course)
65 * + we must also implement mid-session reconfig in pterm.c.
66 * + note this also requires config.c and uxcfg.c to be able
67 * to get hold of the application name.
69 * - Copy All to Clipboard (for what that's worth)
71 * - Clear Scrollback and Reset Terminal
73 * - About (and uxcfg.c must also supply the about box)
79 void cleanup_exit(int code
)
90 * Another bunch of temporary stub functions. These ones will want
91 * removing by means of implementing them properly: libcharset
92 * should invent its own sensible format for codepage names and a
93 * means of enumerating them, and printer_enum needs to be dealt
94 * with somehow or other too.
