libason
ASON is an extension of JSON which specifies a semantic, and allows for pattern expressions that can specify or match groups of JSON values. libason is a simple library for manipulating ASON programmatically in C.
Installation
libason
depends on GNU Readline
if you are going to build the asonq
utility. Rendering the spec requires a
LaTeX
distribution that provides the pdflatex
command. Finally, all builds
of libason
will require the Lemon parser
generator.
As of Fedora 21, the above are provided by the following RPMs in Fedora:
readline-devel
texlive-latex-bin-bin
texlive-texconfig
texlive-texconfig-bin
lemon
libason
can be built and installed with the usual commands:
$ ./configure
$ make
$ make install
Configure arguments
The configure
script can take parameters to change the target install path,
like any Automake configuration script. You can use the --help
option to
print a list of all options. Here are the libason
-specific options:
-
--enable-spec
- Build the ASON specification document. Requires thepdflatex
command. -
--enable-lcov
- Build library with LCOV support.make lcov
will build a code coverage report. -
--with-asonq
- Build and install theasonq
utility as well as the library.
Using the asonq utility
libason
comes with a simple REPL called asonq
. It takes no arguments on the
command line.
Typing an ASON value into asonq
will reduce it to simplest form and repeat
it. You can assign to variables with the :=
operator, such as:
> foo := 6
Type /quit
to exit asonq
.
