Project description

========
Extract and find/replace text based on arbitrary correspondences. This library is a fork from the Textract library by Dean Malmgren. https://github.com/deanmalmgren/textract
Documentation
Installation
To install, you must have Python 3.4+ and pip installed.
pip install convertextract
Some source libraries need to be installed for different operating systems to support various file formats. Visit http://textract.readthedocs.org/en/latest/installation.html for documentation.
=========
Basic CLI Use
Some basic Textract functions are preserved. Please visit http://textract.readthedocs.org for documentation.
Converting a file based on xlsx
convertextract requires two arguments:
- A file containing text to convert (as of Version 1.0.4, this includes .pptx, .docx, .xlsx, and .txt)
- An .xlsx file containing the find/replace correspondences. As of Version 2.0.1 you can also use either .csv files or feed a list of correspondences (as Python dicts) directly into the language keyword argument for either
processorprocess_text
Running the comand:
convertextract path/to/foo.docx -l path/to/bar.xlsx
Will produce a new file path/to/foo_converted.docx which will contain the same content as path/to/foo.docx but with find/replace performed for all correspondences listed in path/to/bar.xlsx.
Creating an .xlsx correspondence sheet
Your correspondence sheet must be set up as follows:
| in | out |
|---|---|
| aa | å |
| oe | ø |
| ae | æ |
Here, this correspondence sheet (do not include headers like "replace with" or "find") would replace all instances of aa, oe, or ae in a given file with å, ø, or æ respectively.
Supported conversions
As of Version 2.0, the following conversions are supported:
- Heiltsuk Doulos Font -> Unicode
convertextract path/to/foo.docx -l hei -t Doulos
- Heiltsuk Times Font -> Unicode
convertextract path/to/foo.docx -l hei -t Times
- Tsilhqot'in Doulos Font -> Unicode
convertextract path/to/foo.docx -l clc -t Doulos
- Navajo Times Font -> Unicode
convertextract path/to/foo.docx -l nav -t Times
Using Regular Expressions
As of Version 1.5, there is support for Regular Expressions. If you do not need to use context-sensitive conversions, you do not need to include them. However, if you do, you should set up your correspondence sheet as follows:
| in | out | context_before | context_after |
|---|---|---|---|
| aa | å | [k,d] | $ |
| aa | æ | t | $ |
| aa | a: |
For more information on how the g2p is acutally processed, please visit https://github.com/roedoejet/g2p.
Use as Python package
You can use the package in a Python script, which returns converted text, but without formatting. Running the script will still create a foo_converted.docx file.
import convertextract
text = convertextract.process('foo.docx', language='bar.xlsx')
You can also use convertextract to just convert text in Python using process_text.
import convertextract
text = convertextract.process_text('test', language=[{'in': 't', 'out': 'p', 'context_before': '^', 'context_after': 'e'}])
