Re: [nail-devel] Line editing capabilities

[Steffen D. N. <sd...@gm...>]

Hello again,

 || * basic line editing capabilities
 || * history
 || * tab completion for commands / folders.

well, just give me one more day and then brave hearts may give it
a try for local private usage.  On the *next* branch we'll have

  WANT_EDITLINE=0 WANT_EDITLINE_READLINE=0
    In user.conf, to be turned on explicitly.  The latter requires
    the former to be true, we won't test otherwise for
    readline(3).

  NAIL_HISTFILE
    A new string option that specifies the place of a history
    file.  Note that we'll do implement a "real" unique history
    with editline(3) by default (unless you turn off the option in
    your .editrc).  Also, ^R (Ctrl-R) will initiate a reverse
    history search (a sufficiently recent editline(3) provided).
    (NAIL_HISTFILE gets expanded before use...)

  prompt
    The prompt is now passed through an escape sequence expander
    before printed; e.g.: `set prompt="\033[31m? \033[0m"'.
    Should always work, unless your terminal doesn't gobble it.

Text lines entered in compose mode will not make it into the
history, which i think is a good thing.  No context-sensitive
completion for quite a long time.  'Fixed a bug with line
continuation as requested by POSIX, too (is there any Mail(1)
which actually does that right?).

Give me yet another week to do testing in respect to signals and
interruption, do some more cleanup, and integrate the mentioned
hetio code for the case when we don't have editline/readline.
Then even the less brave ones may give it a shot.
Ciao,
