Sample 4START

This 4START file demonstrates setting a colorful prompt using ANSI escape sequences and conditionally restoring the previous environment. It will also rebuild the JPSTREE.IDX file if this is the first time 4NT has been launched today.

if %_pipe != 0 .or. %_transient != 0 quit

alias /r c:\jpsoft\aliases
color bri yellow on black

iff "%@filedate[c:\jpstree.idx]" != "%_date" then
    echo Indexing C: in the background.
    start /min /low /c cdd /u c:\

set s=Y
inkey /c /k"YN[Enter]" /w10 /x Restore Previous Environment? (Yn) %%s
iff "%s" eq "Y" .OR. "%s" eq "@28" then
  for %%s in (@c:\JPSOFT\drives.dat) do cdd %%s
  set /r c:\JPSOFT\env.dat
  dirhistory /r c:\JPSOFT\dirhist.dat
  history /r c:\jpsoft\history.dat

set TREEEXCLUDE=d:\;e:\;f:\;g:\;h:\;I:\;J:\;K:\;L:\;M:\;N:\;O:\;P:\;Q:\;R:\;S:\;T:\;U:\;V:\;W:\;X:\;Y:\;Z:\;\\*\*

set TITLEPROMPT=%_cmdproc %_4ver (%_BUILD) in %%_cwd
title %_cmdproc %_4ver (%_BUILD)
rem prompt=`%@exec[@color 15 on %@if[%@remote[%_disk] eq 0,2,4]%+echos [%_cwd%]%+color 14 on 0]$s`
prompt=`%=e[37;%@if[%@remote[%_disk] eq 0,42,41];1m[$P]%=e[33;40;1m$s` 
unset s

Sample 4EXIT

To work around some tricky issues with closing, I aliased my EXIT command.

alias EXIT=c:\jpsoft\_4EXIT.btm

I chose not to use the 4EXIT.btm file directly. So, if a process is closed by clicking on the close button or by Windows shutting down, nothing extra gets done. If I type EXIT from a 4NT prompt however, I can choose whether or not to save my current environment.

if %_transient != 0 quit
msgbox yesno "Save" Save Drive and Environment Settings?
if %_? != 10 *exit
cdd /a > c:\jpsoft\drives.dat
cd >> c:\jpsoft\drives.dat
set > c:\jpsoft\env.dat
dirhistory > c:\jpsoft\dirhist.dat
history > c:\jpsoft\history.dat
