We apologize for the calc v2.14.0.12 source tarball that was missing critical files. While the executable was well tested, our release process was deficient. We are improved our release process and added tests during the release procedure to help verify that we are not regressing in to the "v2.14.0.12 source tarball" issue, among other things. Depending on how things do, you might is several releases come out over a short period of time. The core of calc isn't changing, so the calc executable will be the same as we focus on the Makefiles, our release procedure, and related documentation / help files. We made several changes to the Makefiles. We also added a new README.RELEASE document (see "help release") that is a work in progress. Along the way we discovered a few things that needed to be updated in documentation. See the CHANGES file for details.

full all of the above (in the above order)
|
|
|
|
For example:
|
|
|
|
help usage
|
|
|
|
will print the calc command usage information. One can obtain calc help
|
|
without invoking any startup code by running calc as follows:
|
|
|
|
calc -q help topic
|
|
|
|
where 'topic' is one of the topics listed above.
|
|
|
|
You can also ask for help on a particular builtin function name. For example:
|
|
|
|
help asinh
|
|
help round
|
|
|
|
See:
|
|
|
|
help builtin
|
|
|
|
for a list of builtin functions.
|
|
|
|
Some calc operators have their own help pages:
|
|
|
|
help =
|
|
help ->
|
|
help *
|
|
help .
|
|
help %
|
|
help //
|
|
help #
|
|
|
|
If the -m mode disallows opening files for reading or execution of programs,
|
|
then the help facility will be disabled. See:
|
|
|
|
help usage
|
|
|
|
for details of the -m mode.
|
|
|
|
The help command is able to display installed help files for custom builtin
|
|
functions. However, if the custom name is the same as a standard help
|
|
file, the standard help file will be displayed instead. The custom help
|
|
builtin should be used to directly access the custom help file.
|
|
|
|
For example, the custom help builtin has the same name as the standard
|
|
help file. That is:
|
|
|
|
help help
|
|
|
|
will print this file only. However the custom help builtin will print
|
|
only the custom builtin help file:
|
|
|
|
custom("help", "help");
|
|
|
|
will by-pass a standard help file and look for the custom version directly.
|
|
|
|
As a hack, the following:
|
|
|
|
help custhelp/anything
|
|
|
|
as the same effect as:
|
|
|
|
custom("help", "anything");
|
|
|
|
The man command is an alias for the help command. For example:
|
|
|
|
man sin
|
|
|
|
Any help file that the help command is able to display may be
|
|
displayed by the man command. The man command may only display
|
|
calc help files.
