Somewhat unsurprisingly, I found the original pyline recipe_
while searching for "python grep sed"
(see AUTHORS.rst and LICENSE.psf).
I added an option for setting p = Path(line)
in the eval/compile command context and added it to my dotfiles <https://github.com/westurner/dotfiles/commits/master/src/dotfiles/pyline.py>_
; where it grew tests and an optparse.OptionParser; and is now
promoted to a GitHub_ project with ReadTheDocs_ documentation,
tests with tox and Travis-CI, and a setup.py for PyPi.

Pyline is an ordered MapReduce_ tool:
Input Readers:
* stdin (default)
* file (codecs.open(file, 'r', encoding='utf-8'))
Map Functions:
* Python module imports (-m os)
* Python regex pattern (-r '\(.*\)')
* path library (p from --pathpy OR --pathlib)
* Python codeobj eval output transform:
.. code:: bash
ls | pyline -m os 'line and os.path.abspath(line.strip())'
ls | pyline -r '\(.*\)' 'rgx and (rgx.group(0), rgx.group(1)) or line'
ls | pyline -p 'p and p.abspath() or ("# ".format(line))'
# With an extra outer loop to bind variables in
# (because (_p = p.abspath(); <codeobj>) does not work)
find $PWD | pyline --pathpy -m os -m collections --input-delim='/' \
'p and [collections.OrderedDict((
("p", p),
("_p", _p),
("_p.split()", str(_p).split(os.path.sep)),
("line.rstrip().split()", line.rstrip().split(os.path.sep)),
("l.split()", l.split(os.path.sep)),
("words", words),
("w", w)))
for _p in [p.abspath()]][0]' \
-O json
Partition Function: None
Compare Function:
Result(collections.namedtuple).__cmp__
Reduce Functions:
bool(), sorted()
Output Writers:
ResultWriter classes
.. code:: bash
pyline -O csv
pyline -O tsv
pyline -O json
Install from PyPi_::
pip install pyline
Install from GitHub_ as editable (add a pyline.pth in site-packages)::
pip install -e git+https://github.com/westurner/pyline#egg=pyline
Print help::
pyline --help
Process::
# Print every line (null transform)
cat ~/.bashrc | pyline line
cat ~/.bashrc | pyline l
# Number every line
cat ~/.bashrc | pyline -n l
# Print every word (str.split(input-delim=None))
cat ~/.bashrc | pyline words
cat ~/.bashrc | pyline w
# Split into words and print (default: tab separated)
cat ~/.bashrc | pyline 'len(w) >= 2 and w[1] or "?"'
# Select the last word, dropping lines with no words
pyline -f ~/.bashrc 'w[-1:]'
# Regex matching with groups
cat ~/.bashrc | pyline -n -r '^#(.*)' 'rgx and rgx.group()'
cat ~/.bashrc | pyline -n -r '^#(.*)'
## Original Examples
# Print out the first 20 characters of every line
tail access_log | pyline "line[:20]"
# Print just the URLs in the access log (seventh "word" in the line)
tail access_log | pyline "words[6]"
Work with paths and files::
# List current directory files larger than 1 Kb
ls | pyline -m os \
"os.path.isfile(line) and os.stat(line).st_size > 1024 and line"
# List current directory files larger than 1 Kb
#pip install path.py
ls | pyline -p 'p and p.size > 1024 and line'
