Some folks might think: “you still use RCS”?!? And we will say, hey, at least we switched from SCCS to RCS back in … I think it was around 1994 ... at least we are keeping up! :-) :-) :-) Logs say that SCCS version 18 became RCS version 19 on 1994 March 18. RCS served us well. But now it is time to move on. And so we are switching to git. Calc releases produce a lot of file changes. In the 125 releases of calc since 1996, when I started managing calc releases, there have been 15473 file mods!

Environment variables
|
|
|
|
CALCPATH
|
|
|
|
A :-separated list of directories used to search for
|
|
resource filenames (*.cal files) that do not begin with:
|
|
|
|
/ ./ ../ ~
|
|
|
|
If this variable does not exist, a compiled value
|
|
is used. Typically compiled in value is:
|
|
|
|
.:./cal:~/cal:${CALC_SHAREDIR}:${CUSTOMCALDIR}
|
|
|
|
which is usually:
|
|
|
|
.:./cal:~/cal:/usr/share/calc:/usr/share/calc/custom
|
|
|
|
This value is used by the READ command. It is an error
|
|
if no such readable file is found.
|
|
|
|
The CALCBINDINGS file searches the CALCPATH as well.
|
|
|
|
CALCRC
|
|
|
|
On startup (unless -h or -q was given on the command
|
|
line), calc searches for files along the :-separated
|
|
$CALCRC environment variable.
|
|
|
|
If this variable does not exist, a compiled value
|
|
is used. Typically compiled in value is:
|
|
|
|
${CALC_SHAREDIR}/startup:~/.calcrc:./.calcinit
|
|
|
|
which is usually:
|
|
|
|
/usr/share/calc/startup:~/.calcrc:./.calcinit
|
|
|
|
Missing files along the $CALCRC path are silently ignored.
|
|
|
|
CALCBINDINGS
|
|
|
|
On startup (unless -h or -q was given on the command
|
|
line), calc reads key bindings from the filename specified
|
|
in the $CALCRC environment variable. These key bindings
|
|
are used for command line editing and the command history.
|
|
|
|
If this variable does not exist, a compiled value is used.
|
|
Typically compiled in value is:
|
|
|
|
bindings
|
|
|
|
The bindings file is searched along the CALCPATH. Unlike
|
|
the READ command, a .cal extension is not added.
|
|
|
|
If the file could not be opened, or if standard input is not
|
|
a terminal, then calc will still run, but fancy command line
|
|
editing is disabled.
|
|
|
|
NOTE: If calc was compiled with GNU-readline support, the
|
|
CALCBINDINGS facility is ignored and the standard
|
|
readline mechanisms (see readline(3)) are used.
|
|
|
|
HOME
|
|
|
|
This value is taken to be the home directory of the
|
|
current user. It is used when files begin with '~/'.
|
|
|
|
If this variable does not exist, the home directory password
|
|
entry of the current user is used. If that information
|
|
is not available, '.' is used.
|
|
|
|
PAGER
|
|
|
|
When invoking help, this environment variable is used
|
|
to display a help file.
|
|
|
|
If this variable does not exist, a compiled value
|
|
is used. Typically compiled in value is something
|
|
such as 'more', 'less', 'pg' or 'cat'.
|
|
|
|
SHELL
|
|
|
|
When a !-command is used, the program indicated by
|
|
this environment variable is used.
|
|
|
|
If this variable does not exist, a compiled value
|
|
is used. Typically compiled in value is something
|
|
such as 'sh' is used.
