libxo - A Library for Generating Text, XML, JSON, and HTML Output
The libxo library allows an application to generate text, XML, JSON, and HTML output using a common set of function calls. The application decides at run time which output style should be produced. The application calls a function "xo_emit" to product output that is described in a format string. A "field descriptor" tells libxo what the field is and what it means.
xo_emit(" {:lines/%7ju/%ju} {:words/%7ju/%ju} "
"{:characters/%7ju/%ju}{d:filename/%s}\n",
linect, wordct, charct, file);
Output can then be generated in various style, using the "--libxo" option:
% wc /etc/motd
25 165 1140 /etc/motd
% wc --libxo xml,pretty,warn /etc/motd
<wc>
<file>
<filename>/etc/motd</filename>
<lines>25</lines>
<words>165</words>
<characters>1140</characters>
</file>
</wc>
% wc --libxo json,pretty,warn /etc/motd
{
"wc": {
"file": [
{
"filename": "/etc/motd",
"lines": 25,
"words": 165,
"characters": 1140
}
]
}
}
% wc --libxo html,pretty,warn /etc/motd
<div class="line">
