=============== Getting started

| python-textops3 provides many text operations at string level, list level or whole text level. | These operations can be chained with a 'dotted' or 'piped' notation. | Chained operations are stored into a single lazy object, they will be executed only when an input text will be provided.

Install

To install::

pip install python-textops3

Overview

The usual way to use textops is something like below. IMPORTANT : Note that textops library redefines the python bitwise OR operator '|' in order to use it as a 'pipe' like in a Unix shell::

from textops import *

result = "an input text" | my().chained().operations()

or

for result_item in "an input text" | my().chained().operations(): do_something(result_item)

or

myops = my().chained().operations()

and later in the code, use them :

result = myops("an input text") or result = "an input text" | myops

An "input text" can be :

• a simple string,
• a multi-line string (one string having newlines),
• a list of strings,
• a strings generator,
• a list of lists (useful when you cut lines into columns),
• a list of dicts (useful when you parse a line).

So one can do::

'line1line2line3' | grep('2').tolist() ['line1line2line3'] 'line1\nline2\nline3' | grep('2').tolist() ['line2'] ['line1','line2','line3'] | grep('2').tolist() ['line2'] [['line','1'],['line','2'],['line','3']] | grep('2').tolist() [['line', '2']] [{'line':1},{'line':'2'},{'line':3}] | grep('2').tolist() [{'line': '2'}]

Examples

Piped then dotted notation (recommended)::

print('this is an error\nthis is a warning' | grepi('error').first().upper()) THIS IS AN ERROR

You could use the pipe everywhere (internally a little less optimized, but looks like shell)::

print('this is an error\nthis is a warning' | grepi('error') | first() | strop.upper()) THIS IS AN ERROR

To execute an operation directly from strings, lists or dicts with the dotted notation, you must use textops Extended types : StrExt, ListExt or DictExt::

s = StrExt('this is an error\nthis is a warning') print(s.grepi('error').first().upper()) THIS IS AN ERROR
