Archiving Source Code

Archiving Source Code

Need to backup that source code before you make changes? Yes! Here are two utilities that basically perform the same function of archiving your source.

The utility comes in two flavours - a UDC written by Alfredo Rego at Adager and a command-file version by Ken Robertson here at Robelle.

The Archive UDC

The archive udc copies your source code to a new account whose generated name is based on the current date. You call the udc by typing the following:

  archive filename [,groupname = "Source"]

The account created is called ARyymmdd. The source group is the default. You need to have PM capability in order to run this UDC.

The archive command file takes a slightly different tack by copying your source to a new POSIX directory, called /ar_19yymmdd_hhmm. The file will be placed relative to your home directory. You can override the relative directory by specifying your own.
For example,

  Format:
  archive filename [,groupname = "!HPCWD"]

  Example:
  archive trialmai.ktsrc /SOURCE
  A copy of trialmai.ktsrc was archived to /MISDEV/SOURCE/ar_19971204_1422/trialmai.ktsrc

Archive UDC

archive file, group="Source"
comment  option list
comment  Archives to TODAY's date, as calculated by the system
SetVar nPoint, pos (".", "!file")
if nPoint <> 0 then
  echo There is a dot in position !nPoint of the file's UNQUALIFIED name.
  echo The file's group name is the SECOND parameter, separated by a ","
  echo thus:   ":archive file, group" (the default group is "source",
  echo the default account is aryymmdd, where "yymmdd" are "today").

if HpDate < 10 then

  endif

Archive Command

   echo Usage:  Archive filename
   echo         This command file places a copy of your the input file into an
   echo         archive directory based on today's date and time.  For example,
   echo
   echo         archive foo.src  [ homegroup=!hpcwd ]

   echo

   echo
   echo         You can specify a relative location in which to store your
   echo         archive directory.  For example,

   echo             archive foo.src /DEVL/SOURCE
