PYTHON EDitor: a command to edit lines using Python expressions

For Pythonistas always forgetting the syntax of sed/awk/grep/tr

install

pip install pythoned

(it sets up pythoned in your PATH)

edit mode

You provide a Python str expression, manipulating the line stored in the _ variable (an str):

# get last char of each line
echo -e 'f00\nbar\nf00bar' | pythoned '_[-1]'

output:

0
r
r

filter mode

If the provided expression is a bool instead of an str, then the lines will be filtered according to it:

# keep only lines containing 2 consecutive zeros
echo -e 'f00\nbar\nf00bar' | pythoned '"00" in _'

output:

f00
f00bar

flatten mode

If the provided expression is an Iterable, then its elements will be flattened as separate output lines:

# flatten the chars
echo -e 'f00\nbar\nf00bar' | pythoned 'list(_)'

output:

f
0
0
b
a
r
f
0
0
b
a
r

generator mode

If the _ variable is not used and the expression is an Iterable, then its elements will be separate output lines:

iterables:

# generate ints
pythoned 'range(5)'

output:

0
1
2
3
4

modules

Modules are auto-imported, example with re and json:

# replace digits by Xs in the "bar" field
echo -e '{"bar": "f00"}\n{"bar": "foo"}' | pythoned 're.sub(r"\d", "X", json.loads(_)["bar"])'

output:

fXX
foo
