NAME
     xo_options -- common options for libxo-based commands

DESCRIPTION
     libxo  allows  the  rendering of data into various output styles, including
     text, XML, JSON, and HTML.  libxo uses command line options to trigger ren-
     dering behavior.  Options are recognised in three forms:

     *	 --libxo <options>

     *	 --libxo=<options>

     *	 --libxo:<brief-options>

     The first two forms accept a comma-separated set of words, detailed  below,
     while  the  third form accepts a set of letters, also below.  The triggered
     functionality is identical.

     Option	 Action
     color	 Enable colors/effects for display styles (TEXT, HTML)
     flush	 Flush after each emit call
     flush-line  Flush each line of output
     html	 Emit HTML output
     indent=xx	 Set the indentation level
     info	 Add info attributes (HTML)
     json	 Emit JSON output
     keys	 Emit the key attribute for keys (XML)
     log-gettext Log (via stderr) each gettext(3) string lookup
     log-syslog  Log (via stderr) each syslog message (via xo_syslog)
     no-humanize Ignore the {h:} modifier (TEXT, HTML)
     no-locale	 Do not initialize the locale setting
     no-retain	 Prevent retaining formatting information
     pretty	 Emit pretty-printed output
     retain	 Force retaining formatting information
     text	 Emit TEXT output
     underscores Replace XML-friendly
     units	 Add the 'units' (XML) or 'data-units (HTML) attribute
     warn	 Emit warnings when libxo detects bad calls
     warn-xml	 Emit warnings in XML
     xml	 Emit XML output
     xpath	 Add XPath expressions (HTML)

     The brief options are a set of single-letter aliases for the longer  terms,
     used as a single string:

     Value Equivalent Token
     c
     f	    flush
     F	    flush-line
     H	    html
     I	    info
     i<num> indent=<num>
     J	    json
     k	    keys
     n	    no-humanize
     P	    pretty
     T	    text
     U	    units
     u	    underscore
     W	    warn
     X	    xml
     x	    xpath

     Most of these option are simple and direct, but some require additional de-
     tails:

     flush-line performs line buffering, even when the output is not directed to
     a TTY device.

     info  generates additional data for HTML, encoded in attributes using names
     that state with "data-".

     keys adds a "key" attribute for XML output to indicate that a  leaf  is  an
     identifier for the list member.

     no-humanize  avoids "humanizing" numeric output (see humanize_number(3) for
     details).

     no-locale instructs libxo to avoid translating output to  the  current  lo-
     cale.

     no-retain disables the ability of libxo to internally retain "compiled" in-
     formation about formatting strings.

     underscores can be used with JSON output to change XML -friendly names with
     dashes into JSON -friendly name with underscores.

     warn allows libxo to emit warnings on stderr when application code make in-
     correct  calls.   warn-xml causes those warnings to be placed in XML inside
     the output.

EXAMPLES
     The following are three example invocations of ps(1):

	   ps --libxo json,pretty,warn -ux

	   ps --libxo=xml -lg

	   ps --libxo:Hxc 1
