prjlibs is set of general-purpose libraries for C, sh, and Scheme.

This package is discussed on the prjware list. New releases are announced on the prjware-announce list.


prjlibs is devoid of warranty and is distributed under the GNU General Public License, version 2. But that doesn't mean it's necessarily a good idea for you to distribute modified versions. (That includes repackaging.) I'd like to know if you plan to do that.

This link always points to the latest version (currently 2020.05.04).

Older versions are published for historical interest.

You can get the latest development sources with:

$ git clone git://


The Scheme libraries were written for GNU Guile; I haven't investigated using them with other Scheme implementations. The C and sh libraries are intended to be portable.


slashpackage is a good thing. You can read more about it here. If you don't already have /package, create it (on any filesystem you like, as long as it's accessible by the name “/package”):

# mkdir -p /usr/local/package
# ln -s /usr/local/package /
# chmod +t /package/.

Then run sp-install:

# sp-install prjlibs-VERSION.tar.bz2

Or, if you like to do things manually, unpack the tarball and run package/install:

# cd /package
# bunzip2 < /path/to/prjlibs-VERSION.tar.bz2 |
> tar -xpf -
# cd prog/prjlibs-VERSION
# package/install

Read package/README and package/INSTALL for more detailed instructions.


This documentation so far covers only the C libraries. Some of the Scheme procedures have docstrings in the source code.
