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} "
            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 --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>

  • 'plain' output with a defined field-separator

    'plain' output with a defined field-separator

    Hi. I notice that the output from "df" is tricky to parse, when the mount "device" and/or the mount-point contain spaces.. (yeah, i know... don't ask!!! )

    "mount -p" uses (one or more) tab characters to separate fields, UNLESS the field is over 24 character in which case it uses space. (arrrrgh)

    I see that the idea behind libxo is to enable processing of data, by not having to try and parse human-readable output. This is great, and just what I'd want.

    'df' does indeed have libxo functionality, and whilst this would do the trick, parsing xml or json is overkill. I was hoping it would be possible to have something like:




    or maybe being able to pass a format string in printf format?

    Is this kind of thing generally useful?

    In my particular case, I ended up writing a small C function just to grab the mount "device" and mount-point I needed, but it seemed to me that this what exactly the sort of thing libxo was meant to solve.

    Am I missing something?

    Cheers, Jamie

  • add color role

    add color role

    Oleg Ginzburg writes:

    I wanted to ask - is there some method to be used in the output xo ANSII codes? For normal human text sometimes you want to draw a conclusion in color to make it more human output ;)

    Color would be a useful enhancement, but it can't be done by intermixing escape sequnces with data. It would need to be something more explicit and meaningful, something like:

    xo_emit("The {k:name} {C:green}weighs{C:} {:weight/%d} pounds\n", name, weight);

    The new "C" role would accept a name that would appear as escape sequences for text and "style" attributes for HTML. The list of color names should be freakishly small, to keep it portable, and unknown colors would be ignored (with a warning).

    Hmm... instead of directly making a color style attribute, I'd probably opt for a color class, allowing CSS files to adjust it when/if needed.

    And no, it won't support blinking ;^)

  • libxo/xo_syslog: fix obtaining HOST_NAME_MAX

    libxo/xo_syslog: fix obtaining HOST_NAME_MAX

    _SC_HOST_NAME_MAX has been incorrectly treated as the HOST_NAME_MAX length. This leads to gethostname(3) being passed an accidental value of '72' instead of the actual maximum length allowed for the hostname.

    Fall back to using _POSIX_HOST_NAME_MAX as the remaining code is not ready for introducing sysconf(3) while _POSIX_HOST_NAME_MAX can be used as a proper drop in replacement.

    While here we fix improper accounting that could lead to hostname ending up as an unterminated string. Documentation for gethostname(3) states:

    The gethostname() function returns the standard host name for the current processor, as previously set by sethostname(). The namelen argument specifies the size of the name array. The returned name is null- terminated unless insufficient space is provided.

    We can also read in the sysconf(3) manual:

    _SC_HOST_NAME_MAX Maximum length of a host name (not including the terminating null) as returned from the gethostname() function.

    Hence, to properly store the result of gethostname(3) we need an array of size HOST_NAME_MAX+1 to store the terminating null byte. If we fail to do this we can end up with a non-terminated C string in situations where the current hostname hits the limit.

    Using sysconf(3) API is not a drop in replacement as that would lead to the introduction of variable length arrays (VLA) in the code. To do this properly we would have to call sysconf(3) to obtain hostmax length then malloc(hostmax+1) for the hostname, remember to pass hostmax+1 to gethostname(3) and finally to free it after use.

  • No man page for xo_emit_field()

    No man page for xo_emit_field()

    ~~libxo seems to have convenient APIs to allow various compile-time field names to be used. However, sometimes in life, I have a set of dynamically determined field names, and it wasn't clear to me that the API made that convenient. Possibly I've suffered a documentation spelunking fail, in which case please just point me in the right direction and close. But here is an example:~~

    #include <libxo/xo.h>
     * Sometimes with libxo, I have a set of field names only known at run time.
     * For example, if a program self instruments using hardware performance
     * counters, and because of a limited number of hardware counter registers,
     * the user has to select up to 6 at a time, but we need to support hundreds
     * of potential values.  In this example code, I want to allow the field name
     * to be a string generated at run time .. but I wasn't sure how to do that in 
     * a way that was elegant with libxo.
    what_I_wanted_to_do(const char *variable, const char *value)
            xo_emit("{:%s/%s}", variable, value);
    what_I_did(const char *variable, const char *value)
            char buffer[128];
            snprintf(buffer, sizeof(buffer), "{:%s/%%s}", variable);
            xo_emit(buffer, value);
    main(int argc, char *argv[])
            xo_set_style(NULL, XO_STYLE_JSON);
            xo_set_flags(NULL, XOF_PRETTY);
            what_I_wanted_to_do("L1D_CACHE_ACCESS", "10");
            what_I_did("L1D_CACHE_ACCESS", "10");

    Which outputs:

      "wanted_to_do": {
        "%s": "L1D_CACHE_ACCESS"
      "did": {
        "L1D_CACHE_ACCESS": "10"

    ~~In this scenario, the A72 core we're using has dozens of performance counter events that can be configured, but due to an architectural limit, only 6 can be used at a time. The strings for those registers are already defined in other headers, and I definitely don't want to retype them or do anything to replicate that. Instead, I want to have the user pass the names via the command line, validate them using the PMC library, and then use them as field names with libxo.~~

    ~~Pointers most welcome!~~

  • Better translation support

    Better translation support

    [ Writing up summary of discussion from the Ottawa departure lounge ]

    It would be nice to make the formatting strings more amenable to translation, referring to fields by name and allowing reordering in the translated version. For example, if I want to print the string:

    Push the red button.

    In French this is:

    Poussez le bouton rouge.

    I want to translate this in two chunks, because the button colour is locale-dependent. This is typically done now with gettext as something like:

    printf(_("Push the %s button."), _(red));

    This becomes more complex in C if you have multiple formats, because you need to use the printf modifies to reorder them. Languages like Python that have dictionaries as first-class citizens make this a bit easier, by passing a dictionary for the arguments with the format string including them by name.

    It would be nice to change the xo_emit() calls to do the next best thing in C, where each of the variadic parameters are pairs of name and format string, followed by the variadic parameter. For example:

    xo_emit("Push the {colour} button", "color,s", "red");

    The translation of the format string would also allow other utilities to do the transformation, for example if we emit HTML, transform it, and then want to translate it at the end of a pipeline. libxo should assume that all format strings (though probably not all strings that are inserted, unless they have a modifier character) should be translated.

    xo_emit(3) in FreeBSD points to github page for manual and is not versioned appropriately; can diverge from source code

    xo_emit(3) on FreeBSD points the reader to the github manual instead of providing a description of the lexicon, or an in-depth description of the APIs. The problem with this is that one day when libxo has matured enough in FreeBSD, and the libxo project has been under development long enough, the manual will diverge from the source code.

    The documentation needs to be versioned appropriately, or needs to be distributed with FreeBSD and needs to reference appropriate paths under /usr/share/doc/... .

  • Output containing reserved characters isn't escaped allowing invalid JSON and XML

    Output containing reserved characters isn't escaped allowing invalid JSON and XML

    Some code we were running that used libxo added single quote characters to a string that ended up in a value (via a few levels of indirection) and we were surprised to find that invalid XML was produced. It would be helpful if libxo did this for us or at a minimum least provided a simple vis(3) like function that did the escaping required for the current format mode.

    In our case I ended up using a strsnvis() to blindly encode XML and JSON special characters.

  • Feature request: binary output

    Feature request: binary output

    We're using libxo as part of the SOAAP project to output the results of our security-oriented static analysis. It's working quite well, but when we apply the tool to applications like Chromium we get JSON files of over 1GB. These are hard to work with, not just because they're large, but because we can't seek in the file without parsing.

    It would be helpful if libxo also supported a binary output format with some kind of length encoding so that we could skip large objects and arrays that we're not currently interested in. Perhaps an existing encoding could be employed... for instance, there are C bindings for Cap'n Proto (MIT license).

    libxo output breaks if buffer exceeds 8kb

    While converting the FreeBSD procstat utility to libxo, I noticed that if the output exceeds 8kb, and stdout is a file or a pipe, the content is truncated.

    to reproduce, run some command that produces more than 8192 bytes of data via libxo, and redirect stdout to a file, or pipe it to less or similar. The output will be truncated.

  • libxo inconsistent field truncation

    libxo inconsistent field truncation

    Hi again Phil!

    Tested on FreeBSD 12-stable and 13.0-RELEASE:

    I noticed that "ps" sets the maximum length of the command field to 2048 characters [POSIX2_MAX_LENGTH] via the instructlion "{:command/%-0..2048s}", even when"-ww" is specified. "procstat -e" doesn't. Sigh.

    Anyway, that's another issue, but in the process of checking this, I discovered that whilst libxo honours the maxlength for text, and html, it doesn't for XML, JSON, or CSV

    As an example, try running this, and replacing the libxo output format as appropriate:

    env -i $(jot 500 | awk '{print "testvar_"$0"=dummydummydummydummy"}') sh -c 'ps -wwe -p $$ --libxo xml'

    Is this intentional? I couldn't find anything in the docs mentioning this.

    Is this related to a kludgy fix for ?

    In my opinion, when or if or how fields should be truncated is a thorny issue, but whilst I find many implementations are messy, I still think it should be solely the responsibility of the calling program.

    I.E. I don't think libxo should ignore the max width for some formats and not others...

Sqrt OS is a simulation of an OS scheduler and memory manager using different scheduling algorithms including Highest Priority First (non-preemptive), Shortest Remaining Time Next, and Round Robin.

A process, upon creation, has one of the three states: Running, Ready, Blocked (doing I/O, using other resources than CPU or waiting on unavailable resource).
