filesculpt 0.0.6

Abstraction of Regex find and replace on a file

File Sculpt

current version: v0.0.6

This python module abstracts finding and replacing certain portions of a file through regular expressions. It is a class that creates abstraction of the inner workings of opening and closing a file when finding and replacing its contents.

REQUIREMENTS:

• Python v3.9
• pip

INSTALLATION:

On your command line inside your project directory type the following:

pip install filesculpt

USAGE:

Importing to your code:

from fileSculpt.filesculpt import Sculptfile

EXAMPLE:

Given a file foo.txt containing the text "A quick brown fox jumps under the lazy dog.", we want the text to become "The quick brown fox jumps over the lazy dog"and save it to another file, foorect.txt.

from fileSculpt.filesculpt import Sculptfile

a = Sculptfile(r'^A(.+)under(.+)',["The",0,"over",1],'foo.txt','foorect.text')
a.sculpt()

CLASS DEFINITION:

This is how the Sculptfile object is defined:

Sculptfile( tofind : re , replacewith : list, inpath : str, outpath : str)

CLASS ARGUMENTS:

• tofind - is of type re or regular expression which is used to find/define portions of the file to be replaced with

  See https://docs.python.org/3/howto/regex.html for more info on regular expressions

• replacewith - is a list that should contain either a string or an integer. This list will be rendered in ascending order as replacement for the objects found through regex. An integer refers to the grouping order in a regex query.

  • For example:

    If a file contains 'The quick brown fox' and after regex operations (quick,fox) is obtained, The file's contents can be replaced by assigning a replacewith list formatted as ["A ",0," yellow ",1]. The integers' 0 and 1 represent quick and fox, and when rendered 'A quick yellow fox' is obtained

• inpath - is a string filepath for the file to be read

• outpath - is an optional string filepath for the file to be written after operations are done. If not specified the inpath is set as the outpath and changes will overwrite the file.

CLASS METHODS:

• scuttle() - opens the file specified by inpath as read and returns the regular expression findall() list of the tofind argument

• sculpt() - executes the scuttle method and then executes the replacement specified by replacewith. Writes the result to the file specified in outpath
