File Content Extraction 26.1
Filter SDK C++ Programming Guide

# Source Code

When you enable source code identification, file format detection can identify source code files by language. For example, a file containing Python code would be detected as `Python_Fmt` (531) rather than `ASCII_Text_Fmt` (2).

The default reader for many of the source code formats is `codesr`. This reader filters comments from the source code but not the source code itself. Ignoring the source code is a sensible choice for many use cases. To see which formats are supported by codesr, see codesr.

If you prefer you can filter all of the text from a source code file.

To filter all text from source code files

1. Open `formats.ini` and find the format that you want to configure.

2. Change the reader from `codesr` to `afsr`.

   For example, to filter all Python source code you would change:

   `531=code`

   to

   `531=af`

3. Save and close the configuration file.
