<p/> As discussed in the section on
|
|
POKI_PUT_LINK_FOR_PAGE(file-formats.html)HERE, Miller supports several
|
|
different file formats. Different tools are good at different things, so
|
|
it’s important to be able to move data into and out of other languages.
|
|
<b>CSV</b> and <b>JSON</b> are well-known, of course; here are some examples
|
|
using <b>DKVP</b> format, with <b>Ruby</b> and <b>Python</b>.

<button style="font-weight:bold;color:maroon;border:0" padding=0 onclick="toggle_by_name('section_toggle_dkvp_python');" href="javascript:;">Toggle section visibility</button>
|
|
<div id="section_toggle_dkvp_python" style="display: block">
|

|
|
Here are the I/O routines:
|
|
|
|
POKI_INCLUDE_ESCAPED(polyglot-dkvp-io/dkvp_io.py)HERE
|
|
|
|
And here is an example using them:
|
|
|
|
POKI_RUN_COMMAND{{cat polyglot-dkvp-io/example.py}}HERE
|
|
|
|
Run as-is:
|
|
|
|
POKI_RUN_COMMAND{{python polyglot-dkvp-io/example.py < data/small}}HERE
|
|
|
|
Run as-is, then pipe to Miller for pretty-printing:
|
|
|
|
POKI_RUN_COMMAND{{python polyglot-dkvp-io/example.py < data/small | mlr --opprint cat}}HERE
|
