Streaming
---------

It's possible to pipe data into eliot-tree, from a tailed log for example, and
have it rendered incrementally. There is a caveat though: Trees are only
rendered once an end message—a success or failure status—for the tree's root
action appears in the data.

Usage from Python
-----------------

.. code-block:: python

   import json, sys
   from eliottree import tasks_from_iterable, render_tasks
   # Or `codecs.getwriter('utf-8')(sys.stdout).write` on Python 2.
   render_tasks(sys.stdout.write, tasks, colorize=True)

See :code:`help(render_tasks)` and :code:`help(tasks_from_iterable)` from a
Python REPL for more information.

Usage from the command-line
---------------------------

.. code-block::

   $ eliot-tree
   usage: eliot-tree [-h] [-u UUID] [-i KEY] [--raw]
                     [--color {always,auto,never}] [--no-colorize] [-l LENGTH]
                     [--select QUERY] [--start START] [--end END]
                     [FILE [FILE ...]]

   Display an Eliot log as a tree of tasks.

   positional arguments:
     FILE                  Files to process. Omit to read from stdin.

   optional arguments:
     -h, --help            show this help message and exit
     -u UUID, --task-uuid UUID
                           Select a specific task by UUID
     -i KEY, --ignore-task-key KEY
                           Ignore a task key, use multiple times to ignore
                           multiple keys. Defaults to ignoring most Eliot
                           standard keys.
     --raw                 Do not format some task values (such as UTC
                           timestamps) as human-readable
     --color {always,auto,never}
                           Color the output. Defaults based on whether the output
                           is a TTY.
     -l LENGTH, --field-limit LENGTH
                           Limit the length of field values to LENGTH or a
                           newline, whichever comes first. Use a length of 0 to
                           output the complete value.
     --select QUERY        Select tasks to be displayed based on a jmespath
                           query, can be specified multiple times to mimic
                           logical AND. If any child task is selected the entire
                           top-level task is selected. See <http://jmespath.org/>
     --start START         Select tasks whose timestamp occurs after (or on) an
                           ISO8601 date.
     --end END             Select tasks whose timestamp occurs before an ISO8601
                           date.
