<p id="doc_section_1_p_1">libxo - A Library for Generating Text, XML, JSON, and HTML Output</p>
<p id="doc_section_1_p_2">You want to prepare for the future, but you need to live in the present. You'd love a flying car, but need to get to work today. You want to support features like XML, JSON, and HTML rendering to allow integration with NETCONF, REST, and web browsers, but you need to make text output for command line users.</p>
<p id="doc_section_1_p_3">And you don't want multiple code paths that can't help but get out of sync:</p>
<div id="doc_figure_u.1"></div> <pre>
    /* None of this "if (xml) {... } else {...}"  logic */
    if (xml) {
        /* some code to make xml*/
    } else {
        /* other code to make text */
        /* oops forgot to add something on both clauses! */
    }

    /* And ifdefs are right out. */
    #ifdef MAKE_XML
        /* icky */
    #else
        /* pooh */
    #endif
            </pre> <p id="doc_section_1_p_5">But you'd really, really like all the fancy features that modern encoding formats can provide. libxo can help.</p>
<p id="doc_section_1_p_6">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. Each field descriptor is placed in braces with a printf-like format string (<a href="#format-strings" title="Format Strings">Section�3.2</a>):</p>
<div id="doc_figure_u.2"></div> <pre>
    xo_emit(" {:lines/%7ju} {:words/%7ju} "
            "{:characters/%7ju} {d:filename/%s}\n",
            linect, wordct, charct, file);
            </pre> <p id="doc_section_1_p_8">Each field can have a role, with the 'value' role being the default, and the role tells libxo how and when to render that field (see <a href="#field-roles" title="Field Roles">Section�3.2.1</a> for details). Modifiers change how the field is rendered in different output styles (see <a href="#field-modifiers" title="Field Modifiers">Section�3.2.2</a> for details. Output can then be generated in various style, using the "&#8209;&#8209;libxo" option:</p>

</h2>
<p id="doc_section_2_1_p_1">You can retrieve the source for libxo in two ways:</p>
<p id="doc_section_2_1_p_2">A) Use a "distfile" for a specific release. We use github to maintain our releases. Visit github release page (<a href="https://github.com/Juniper/libxo/releases">https://github.com/Juniper/libxo/releases</a>) to see the list of releases. To download the latest, look for the release with the green "Latest release" button and the green "libxo&#8209;RELEASE.tar.gz" button under that section.</p>
<p id="doc_section_2_1_p_3">After downloading that release's distfile, untar it as follows:</p>
<div id="doc_figure_u.5"></div> <pre>
    tar -zxf libxo-RELEASE.tar.gz
    cd libxo-RELEASE
            </pre> <p id="doc_section_2_1_p_5">[Note: for Solaris users, your "tar" command lacks the "&#8209;z" flag, so you'll need to substitute "gzip -dc "file" | tar xf -" instead of "tar -zxf "file"".]</p>
<p id="doc_section_2_1_p_6">B) Use the current build from github. This gives you the most recent source code, which might be less stable than a specific release. To build libxo from the git repo:</p>
<div id="doc_figure_u.6"></div> <pre>
    git clone https://github.com/Juniper/libxo.git
    cd libxo
            </pre> <p id="doc_section_2_1_p_8">_BE AWARE_: The github repository does _not_ contain the files generated by "autoreconf", with the notable exception of the "m4" directory. Since these files (depcomp, configure, missing, install-sh, etc) are generated files, we keep them out of the source code repository.</p>
<p id="doc_section_2_1_p_9">This means that if you download the a release distfile, these files will be ready and you'll just need to run "configure", but if you download the source code from svn, then you'll need to run "autoreconf" by hand. This step is done for you by the "setup.sh" script, described in the next section.</p>

</h1>
<p id="doc_section_3_p_1">Most unix commands emit text output aimed at humans. It is designed to be parsed and understood by a user. Humans are gifted at extracting details and pattern matching in such output. Often programmers need to extract information from this human-oriented output. Programmers use tools like grep, awk, and regular expressions to ferret out the pieces of information they need. Such solutions are fragile and require maintenance when output contents change or evolve, along with testing and validation.</p>
<p id="doc_section_3_p_2">Modern tool developers favor encoding schemes like XML and JSON, which allow trivial parsing and extraction of data. Such formats are simple, well understood, hierarchical, easily parsed, and often integrate easier with common tools and environments. Changes to content can be done in ways that do not break existing users of the data, which can reduce maintenance costs and increase feature velocity.</p>
<p id="doc_section_3_p_3">In addition, modern reality means that more output ends up in web browsers than in terminals, making HTML output valuable.</p>
<p id="doc_section_3_p_4">libxo allows a single set of function calls in source code to generate traditional text output, as well as XML and JSON formatted data. HTML can also be generated; "&lt;div&gt;" elements surround the traditional text output, with attributes that detail how to render the data.</p>
<p id="doc_section_3_p_5">A single libxo function call in source code is all that's required:</p>
<div id="doc_figure_u.17"></div> <pre>
    xo_emit("Connecting to {:host}.{:domain}...\n", host, domain);

    TEXT:

      "domain": "example.com"

<ul>
<li>TEXT output can be display on a terminal session, allowing compatibility with traditional command line usage.</li>
<li>XML output is suitable for tools like XPath and protocols like NETCONF.</li>

<li>HTML can be matched with a small CSS file to permit rendering in any HTML5 browser.</li>
</ul>
<p id="doc_section_3_1_p_3">In general, XML and JSON are suitable for encoding data, while TEXT is suited for terminal output and HTML is suited for display in a web browser (see <a href="#xohtml" title="xohtml">Section�8</a>).</p>

    90      .

            </pre> <p id="doc_section_3_1_1_p_5">Simple, direct, obvious. But it's only making text output. Imagine using a single code path to make TEXT, XML, JSON or HTML, deciding at run time which to generate.</p>
<p id="doc_section_3_1_1_p_6">libxo expands on the idea of printf format strings to make a single format containing instructions for creating multiple output styles:</p>
<div id="doc_figure_u.20"></div> <pre>

</h2>
<p id="doc_section_3_2_p_1">libxo uses format strings to control the rendering of data into the various output styles. Each format string contains a set of zero or more field descriptions, which describe independent data fields. Each field description contains a set of modifiers, a content string, and zero, one, or two format descriptors. The modifiers tell libxo what the field is and how to treat it, while the format descriptors are formatting instructions using printf-style format strings, telling libxo how to format the field. The field description is placed inside a set of braces, with a colon (":") after the modifiers and a slash ("/") before each format descriptors. Text may be intermixed with field descriptions within the format string.</p>
<p id="doc_section_3_2_p_2">The field description is given as follows:</p>
<div id="doc_figure_u.24"></div> <pre>
    '{' [ role | modifier ]* [',' long-names ]* ':' [ content ]
            [ '/' field-format [ '/' encoding-format ]] '}'
            </pre> <p id="doc_section_3_2_p_4">The role describes the function of the field, while the modifiers enable optional behaviors. The contents, field-format, and encoding-format are used in varying ways, based on the role. These are described in the following sections.</p>
<p id="doc_section_3_2_p_5">In the following example, three field descriptors appear. The first is a padding field containing three spaces of padding, the second is a label ("In stock"), and the third is a value field ("in&#8209;stock"). The in-stock field has a "%u" format that will parse the next argument passed to the xo_emit function as an unsigned integer.</p>
<div id="doc_figure_u.25"></div> <pre>

<p id="doc_section_3_2_p_8">While roles and modifiers typically use single character for brevity, there are alternative names for each which allow more verbose formatting strings. These names must be preceded by a comma, and may follow any single-character values:</p>

<p id="doc_section_3_2_4_p_8">UTF-8 and locale-encoded strings can use multiple bytes to encode one column of data. The traditional "precision'" (aka "max&#8209;width") value for "%s" printf formatting becomes overloaded since it specifies both the number of bytes that can be safely referenced and the maximum number of columns to emit. xo_emit uses the precision as the former, and adds a third value for specifying the maximum number of columns.</p>
<p id="doc_section_3_2_4_p_9">In this example, the name field is printed with a minimum of 3 columns and a maximum of 6. Up to ten bytes of data at the location given by 'name' are in used in filling those columns.</p>

<p id="doc_section_3_2_10_p_1">Many compilers and tool chains support validation of printf-like arguments. When the format string fails to match the argument list, a warning is generated. This is a valuable feature and while the formatting strings for libxo differ considerably from printf, many of these checks can still provide build-time protection against bugs.</p>
<p id="doc_section_3_2_10_p_2">libxo provide variants of functions that provide this ability, if the "&#8209;&#8209;enable&#8209;printflike" option is passed to the "configure" script. These functions use the "_p" suffix, like "xo_emit_p()", xo_emit_hp()", etc.</p>
<p id="doc_section_3_2_10_p_3">The following are features of libxo formatting strings that are incompatible with printf-like testing:</p>
<p id="doc_section_3_2_10_p_4"> </p>
<ul>
<li>implicit formats, where "{:tag}" has an implicit "%s";</li>
<li>the "max" parameter for strings, where "{:tag/%4.10.6s}" means up to ten bytes of data can be inspected to fill a minimum of 4 columns and a maximum of 6;</li>
<li>percent signs in strings, where "{:filled}%" makes a single, trailing percent sign;</li>
<li>the "l" and "h" modifiers for strings, where "{:tag/%hs}" means locale-based string and "{:tag/%ls}" means a wide character string;</li>
<li>distinct encoding formats, where "{:tag/#%s/%s}" means the display styles (text and HTML) will use "#%s" where other styles use "%s";</li>
</ul>
<p id="doc_section_3_2_10_p_5">If none of these features are in use by your code, then using the "_p" variants might be wise.</p>

<a id="handles" href="#handles">Handles</a>
</h2>
<p id="doc_section_5_1_p_1">libxo uses "handles" to control its rendering functionality. The handle contains state and buffered data, as well as callback functions to process data.</p>
<p id="doc_section_5_1_p_2">Handles give an abstraction for libxo that encapsulates the state of a stream of output. Handles have the data type "xo_handle_t" and are opaque to the caller.</p>
<p id="doc_section_5_1_p_3">The library has a default handle that is automatically initialized. By default, this handle will send text style output (XO_STYLE_TEXT) to standard output. The xo_set_style and xo_set_flags functions can be used to change this behavior.</p>
<p id="doc_section_5_1_p_4">For the typical command that is generating output on standard output, there is no need to create an explicit handle, but they are available when needed, e.g., for daemons that generate multiple streams of output.</p>
<p id="doc_section_5_1_p_5">Many libxo functions take a handle as their first parameter; most that do not use the default handle. Any function taking a handle can be passed NULL to access the default handle. For the convenience of callers, the libxo library includes handle-less functions that implicitly use the default handle.</p>
<p id="doc_section_5_1_p_6">For example, the following are equivalent:</p>
<div id="doc_figure_u.90"></div> <pre>
    xo_emit("test");
    xo_emit_h(NULL, "test");
            </pre> <p id="doc_section_5_1_p_8">Handles are created using xo_create() and destroy using xo_destroy().</p>

<p id="doc_section_5_6_p_1">The number of encoding schemes in current use is staggering, with new and distinct schemes appearing daily. While libxo provide XML, JSON, HMTL, and text natively, there are requirements for other encodings.</p>
<p id="doc_section_5_6_p_2">Rather than bake support for all possible encoders into libxo, the API allows them to be defined externally. libxo can then interfaces with these encoding modules using a simplistic API. libxo processes all functions calls, handles state transitions, performs all formatting, and then passes the results as operations to a customized encoding function, which implements specific encoding logic as required. This means your encoder doesn't need to detect errors with unbalanced open/close operations but can rely on libxo to pass correct data.</p>
<p id="doc_section_5_6_p_3">By making a simple API, libxo internals are not exposed, insulating the encoder and the library from future or internal changes.</p>

<p id="doc_section_5_6_2_p_4"> </p>
<ul>
<li>xei_version is the version number of the API as implemented within libxo. This version is currently as 1 using XO_ENCODER_VERSION. This number can be checked to ensure compatibility. The working assumption is that all versions should be backward compatible, but each side may need to accurately know the version supported by the other side. xo_encoder_library_init can optionally check this value, and must then set it to the version number used by the encoder, allowing libxo to detect version differences and react accordingly. For example, if version 2 adds new operations, then libxo will know that an encoding library that set xei_version to 1 cannot be expected to handle those new operations.</li>
<li>xei_handler must be set to a pointer to a function of type xo_encoder_func_t, as defined in xo_encoder.h. This function takes a set of parameters: -- xop is a pointer to the opaque xo_handle_t structure -- op is an integer representing the current operation -- name is a string whose meaning differs by operation -- value is a string whose meaning differs by operation -- private is an opaque structure provided by the encoder</li>

<p id="doc_section_10_1_1_p_1">In 2001, we added an XML API to the JUNOS operating system, which is built on top of FreeBSD. Eventually this API became standardized as the NETCONF API (RFC 6241). As part of this effort, we modified many FreeBSD utilities to emit XML, typically via a "&#8209;X" switch. The results were mixed. The cost of maintaining this code, updating it, and carrying it were non-trivial, and contributed to our expense (and the associated delay) with upgrading the version of FreeBSD on which each release of JUNOS is based.</p>
<p id="doc_section_10_1_1_p_2">A recent (2014) effort within JUNOS aims at removing our modifications to the underlying FreeBSD code as a means of reducing the expense and delay in tracking HEAD. JUNOS is structured to have system components generate XML that is rendered by the CLI (think: login shell) into human-readable text. This allows the API to use the same plumbing as the CLI, and ensures that all components emit XML, and that it is emitted with knowledge of the consumer of that XML, yielding an API that have no incremental cost or feature delay.</p>
<p id="doc_section_10_1_1_p_3">libxo is an effort to mix the best aspects of the JUNOS strategy into FreeBSD in a seemless way, allowing commands to make printf-like output calls with a single code path.</p>

</h3>
<p id="doc_section_10_1_2_p_1">The history is both long and short: libxo's functionality is based on what JUNOS does in a data modeling language called ODL (output definition language). In JUNOS, all subcomponents generate XML, which is feed to the CLI, where data from the ODL files tell is how to render that XML into text. ODL might had a set of tags like:</p>
<div id="doc_figure_u.145"></div> <pre>
     tag docsis-state {
         help "State of the DOCSIS interface";
         type string;

<p id="doc_section_10_1_2_p_4">The roles and modifiers describe these details.</p>
<p id="doc_section_10_1_2_p_5">In moving these ideas to bsd, two things had to happen: the formatting had to happen at the source since BSD won't have a JUNOS-like CLI to do the rendering, and we can't depend on external data models like ODL, which was seen as too hard a sell to the BSD community.</p>
<p id="doc_section_10_1_2_p_6">The results were that the xo_emit strings are used to encode the roles, modifiers, names, and formats. They are dense and a bit cryptic, but not so unlike printf format strings that developers will be lost.</p>

</h3>
<p id="doc_section_10_1_3_p_1">To make useful, consistent field names, follow these guidelines:</p>
<p id="doc_section_10_1_3_p_2"> </p>
<dl>
<dt>Use lower case, even for TLAs</dt>
<dd>Lower case is more civilized. Even TLAs should be lower case to avoid scenarios where the differences between "XPath" and "Xpath" drive your users crazy. Using "xpath" is simpler and better.</dd>
<dt>Use hyphens, not underscores</dt>
<dd>Use of hyphens is traditional in XML, and the XOF_UNDERSCORES flag can be used to generate underscores in JSON, if desired. But the raw field name should use hyphens.</dd>
<dt>Use full words</dt>
<dd>Don't abbreviate especially when the abbreviation is not obvious or not widely used. Use "data&#8209;size", not "dsz" or "dsize". Use "interface" instead of "ifname", "if&#8209;name", "iface", "if", or "intf".</dd>
<dt>Use &lt;verb&gt;-&lt;units&gt;</dt>
<dd>Using the form &lt;verb&gt;-&lt;units&gt; or &lt;verb&gt;-&lt;classifier&gt;-&lt;units&gt; helps in making consistent, useful names, avoiding the situation where one app uses "sent&#8209;packet" and another "packets&#8209;sent" and another "packets&#8209;we&#8209;have&#8209;sent". The &lt;units&gt; can be dropped when it is obvious, as can obvious words in the classification. Use "receive&#8209;after&#8209;window&#8209;packets" instead of "received&#8209;packets&#8209;of&#8209;data&#8209;after&#8209;window".</dd>
<dt>Reuse existing field names</dt>
<dd>Nothing's worse than writing expressions like:</dd>
</dl>
<div id="doc_figure_u.146"></div> <pre>
    if ($src1/process[pid == $pid]/name ==
        $src2/proc-table/proc-list
                   /proc-entry[process-id == $pid]/proc-name) {
        ...
    }
            </pre> <p id="doc_section_10_1_3_p_4">Find someone else who is expressing similar data and follow their fields and hierarchy. Remember the quote is not "Consistency is the hobgoblin of little minds", but "A foolish consistency is the hobgoblin of little minds".</p>
<p id="doc_section_10_1_3_p_5"> </p>
<dl>
<dt>Use containment as scoping</dt>
<dd>In the previous example, all the names are prefixed with "proc&#8209;", which is redundant given that they are nested under the process table.</dd>
<dt>Think about your users</dt>
<dd>Have empathy for your users, choosing clear and useful fields that contain clear and useful data. You may need to augment the display content with xo_attr() calls (<a href="#xo_attr" title="Attributes (xo_attr)">Section�5.2.2</a>) or "{e:}" fields (<a href="#e-modifier" title="The Encoding Modifier ({e:})">Section�3.2.2.4</a>) to make the data useful.</dd>
<dt>Don't use an arbitrary number postfix</dt>
<dd>What does "errors2" mean? No one will know. "errors&#8209;after&#8209;restart" would be a better choice. Think of your users, and think of the future. If you make "errors2", the next guy will happily make "errors3" and before you know it, someone will be asking what's the difference between errors37 and errors63.</dd>
<dt>Be consistent, uniform, unsurprising, and predictable</dt>
<dd>Think of your field vocabulary as an API. You want it useful, expressive, meaningful, direct, and obvious. You want the client application's programmer to move between without the need to understand a variety of opinions on how fields are named. They should see the system as a single cohesive whole, not a sack of cats.</dd>
</dl>
<p id="doc_section_10_1_3_p_6">Field names constitute the means by which client programmers interact with our system. By choosing wise names now, you are making their lives better.</p>
<p id="doc_section_10_1_3_p_7">After using "xolint" to find errors in your field descriptors, use "xolint -V" to spell check your field names and to detect different names for the same data. "dropped&#8209;short" and "dropped&#8209;too&#8209;short" are both reasonable names, but using them both will lead users to ask the difference between the two fields. If there is no difference, use only one of the field names. If there is a difference, change the names to make that difference more obvious.</p>

<p id="doc_section_11_3_2_p_4">Since text outside of output fields is passed verbatim, other roles are less important, but their proper use can help make output more useful. The "note" and "label" roles allow HTML output to recognize the relationship between text and the associated values, allowing appropriate "hover" and "onclick" behavior. Using the "units" role allows the presentation layer to perform conversions when needed. The "warning" and "error" roles allows use of color and font to draw attention to warnings. The "padding" role makes the use of vital whitespace more clear (<a href="#padding-role" title="The Padding Role ({P:})">Section�3.2.1.6</a>).</p>
<p id="doc_section_11_3_2_p_5">The "title" role indicates the headings of table and sections. This allows HTML output to use CSS to make this relationship more obvious.</p>

    How do I use libxo to support internationalization?
            </pre> <p id="doc_section_11_5_p_2">libxo allows format and field strings to be used a keys into message catalogs to enable translation into a user's native language by invoking the standard gettext(3) functions.</p>
<p id="doc_section_11_5_p_3">gettext setup is a bit complicated: text strings are extracted from source files into "portable object template" (.pot) files using the "xgettext" command. For each language, this template file is used as the source for a message catalog in the "portable object" (.po) format, which are translated by hand and compiled into "machine object" (.mo) files using the "msgfmt" command. The .mo files are then typically installed in the /usr/share/locale or /opt/local/share/locale directories. At run time, the user's language settings are used to select a .mo file which is searched for matching messages. Text strings in the source code are used as keys to look up the native language strings in the .mo file.</p>
<p id="doc_section_11_5_p_4">Since the xo_emit format string is used as the key into the message catalog, libxo removes unimportant field formatting and modifiers from the format string before use so that minor formatting changes will not impact the expensive translation process. We don't want a developer change such as changing "/%06d" to "/%08d" to force hand inspection of all .po files. The simplified version can be generated for a single message using the "xopo -s &lt;text&gt;" command, or an entire .pot can be translated using the "xopo -f &lt;input&gt; -o &lt;output&gt;" command.</p>
<div id="doc_figure_u.205"></div> <pre>
    EXAMPLE:
        % xopo -s "There are {:count/%u} {:event/%.6s} events\n"
        There are {:count} {:event} events\n

    Recommended workflow:
        # Extract text messages
        xgettext --default-domain=foo --no-wrap \
            --add-comments --keyword=xo_emit --keyword=xo_emit_h \
            --keyword=xo_emit_warn -C -E -n --foreign-user \
            -o foo.pot.raw foo.c

        # Simplify format strings for libxo
        xopo -f foo.pot.raw -o foo.pot

        # For a new language, just copy the file
        cp foo.pot po/LC/my_lang/foo.po

        # For an existing language:
        msgmerge --no-wrap po/LC/my_lang/foo.po \
                foo.pot -o po/LC/my_lang/foo.po.new

        # Now the hard part: translate foo.po using tools
        # like poedit or emacs' po-mode

        # Compile the finished file; Use of msgfmt's "-v" option is
        # strongly encouraged, so that "fuzzy" entries are reported.
        msgfmt -v -o po/my_lang/LC_MESSAGES/foo.mo po/my_lang/foo.po

        # Install the .mo file
        sudo cp po/my_lang/LC_MESSAGES/foo.mo \
                /opt/local/share/locale/my_lang/LC_MESSAGE/
            </pre> <p id="doc_section_11_5_p_6">Once these steps are complete, you can use the "gettext" command to test the message catalog:</p>
