LibHdate is a small library for the Hebrew calendar, dates, holidays, and reading sequence. It is written in C and includes bindings for pascal, perl, python, php, ruby.
hcal and hdate are small example command line programs written in C.
Refer to the following files: INSTALL instructions how to install this package USE basic example of how to use one of the library functions in a C program, how to compile it, and how to run it. NEWS press-release style information of the current release Changelog more detailed list of project activity over many releases
Refer to the man pages and examples directory for further documentation and examples.
This release brings many new options, features, and bug fixes to the two example programs hcal and hdate. The changes to the underlying function library include a few minor bug fixes, deprecation of a series of string functions in favor of a single new one with better memory allocation, and hard-coding of core elements of the Hebrew localization so that Hebrew can be displayed in all locales. The documentation in the man pages and in the new configuration file should be sufficient.

This package is available for most major operating systems, so in most cases if you just want to use the command line programs, the following instructions are unnecessary; just install your distribution's pre-built package, or a packaged binary from a reliable repository compatable with your distribution.
GNU toolchain, ie. gcc, libtoolize, autoreconf, and make. Your
distribution may package these as build-essential, libtool,
autoconf, and automake.
This package was tested using the following toolchain versions:
libtool (GNU libtool) 2.4.6
autoconf (GNU Autoconf) 2.69
automake (GNU automake) 1.16.1
gcc (Debian 8.2.0-4) 8.2.0
ldd (Debian GLIBC 2.27-5) 2.27
Additonally, in order to build the bindings to other languages: swig 3.0.10 g++ (Debian 8.2.0-4) 8.2.0 g++-multilib 8.2.0 (for php) php 5.6.36 python 2.7 perl 5.26.2
Run the provided shell script autogen.sh.
The script will invoke libtoolize, autoreconf, configure, and
make. Upon success, you can either use the built files at their
current paths, or you can perform sudo make install to install
them system-wide on your machine.
The extensive manuals and documentation for the elements of the GNU toolchain are a reliable source of interminable travail, frustration, torture, and enlightenment for all those who would dare turn to them. The search engine of your choice also works.
