project provides a number of
gawk extensions, including one for
processing XML files. This is the evolution of the original
There are a number of extensions. Some of the more interesting ones are:
abortextension. It allows you to exit immediately from your
awkprogram without running the
jsonextension. This serializes a multidimensional array into a JSON string, and can deserialize a JSON string into a
gawkarray. This extension is interesting since it is written in C++ instead of C.
gawk’s native MPFR support does not.
You can check out the code for the
using the Git distributed source
code control system. The command is as follows:
git clone git://git.code.sf.net/p/gawkextlib/code gawkextlib-code
You will need to have the RapidJson
JSON parser library installed in order to build and use the
You will need to have the Expat XML parser library installed in order to build and use the XML extension.
The simple recipe for building and testing
gawkextlib is as follows.
First, build and install
cd .../path/to/gawk/code ./configure --prefix=/tmp/newgawk Install in /tmp/newgawk for now make && make check Build and check that all is OK make install Install gawk
Next, go to https://sourceforge.net/projects/gawkextlib/files to
gawkextlib and any extensions that you would like to build.
The README file at that site explains how to build the code. If you
gawk in a non-standard location, you will need to
specify ‘./configure --with-gawk=/path/to/gawk’ to find it.
You may need to use the
to install both
gawkextlib, depending upon
how your system works.
If you write an extension that you wish to share with other
gawk users, consider doing so through the
