Fixed a mistake in "help intro" where some inserted text
changed the value of "." and thus made the next result
incorrect.
Clarified in "help factor" that 1 is returned if no
factor below the limit was found.
Removed Makefile variable ${MAKEFILE_REV}.
The missing cscript/square.calc file has been restored.
Fixed compiler errors and warnings related to GCC.
In particular, gcc/9.3.1 and gcc/10.2.1 now compile
calc without any compiler errors or warnings,
even with -Werror -Wextra -pedantic.
To print out information about the calc compliation
environment, we added the following make rule:
make calcinfo
Improved how 'make debug' operates.
Moved help/contrib to CONTRIB-CODE. The help/contrib file
is now build from a copy of CONTRIB-CODE.
Created a new calc bug report Email address. Created a new calc
question Email address. Created a new calc contribution Email
address. See the BUGS file for details.
Added "help questions" to print the QUESIONS help file.
If the environment variable $CALCHELP is defined and is non-empty,
then calc help files will be in the direcgory by the $CALCHISTFILE
environment variable.
If the environment variable $CALCCUSTOMHELP is defined and is
non-empty, then custom calc help files will be in the direcgory
by the $CALCCUSTOMHELP environment variable.

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, or if this
|
|
variable is an empty string, 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, or if this
|
|
variable is an empty string, 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, or if this
|
|
variable is an empty string, 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, or if this
|
|
variable is an empty string, 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, or if this
|
|
variable is an empty string, a compiled value
|
|
is used. Typically compiled in value is something
|
|
such as 'sh' is used.
|
|
|
|
CALCHISTFILE
|
|
|
|
This value is taken to be the calc history file.
|
|
|
|
If this variable does not exist, or if this
|
|
variable is an empty string, then ~/.calc_history
|
|
is used.
|
|
|
|
CALCHELP
|
|
|
|
Location of the calc help directory.
|
|
|
|
If this variable does not exist, or if this
|
|
variable is an empty string, then ${HELPDIR}
|
|
|
|
CALCCUSTOMHELP
|
|
|
|
Location of the calc custom help directory.
|
|
|
|
If this variable does not exist, or if this
|
|
variable is an empty string, then ${CUSTOMHELPDIR}
|
|
is used.
