libxo ===== 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. Imagine a simplified ``wc`` that emits its output fields in a single xo_emit call: ``` 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"> <div class="text"> </div> <div class="data" data-tag="lines"> 25</div> <div class="text"> </div> <div class="data" data-tag="words"> 165</div> <div class="text"> </div> <div class="data" data-tag="characters"> 1140</div> <div class="text"> </div> <div class="data" data-tag="filename">/etc/motd</div> </div> ``` View the beautiful documentation at: http://juniper.github.io/libxo/libxo-manual.html [](https://github.com/Juniper/libxo) |
