Convert RST to LOG

Why Convert RST to LOG?

Converting reStructuredText (RST) documents to LOG (plain text) format is useful when you need to extract the pure text content from your documentation without any markup. This is particularly valuable for text processing, content indexing, or when you need a simplified version of your documentation.

Plain text LOG files are universally readable and require no special software. They can be opened in any text editor, processed by command-line tools like grep, awk, and sed, and easily integrated into data processing pipelines. This makes them ideal for automated systems that need to extract and analyze text content.

The conversion strips all RST markup including headers underlines, directive syntax, cross-references, and formatting marks. What remains is clean, readable text that preserves the document's logical flow and content hierarchy through simple indentation and line breaks.

This conversion is particularly useful for creating searchable text indexes, generating content for full-text search engines, archiving documentation in a minimal format, or preparing text for natural language processing applications.

Key Benefits of Converting RST to LOG:

• Universal Compatibility: Works with any text editor or processing tool
• Minimal File Size: No markup overhead means smaller files
• Easy Processing: Perfect for grep, awk, sed, and other text tools
• Search Indexing: Clean text for full-text search engines
• Archival Format: Simple format that will always be readable
• Script Integration: Easy to process in any programming language
• Content Extraction: Get just the text without markup noise

Example 2: Code Blocks and Directives

Input RST file (code_example.rst):

API Reference
=============

.. code-block:: python
   :linenos:

   def calculate_total(items):
       """Calculate the total price."""
       return sum(item.price for item in items)

.. warning::
   This function does not handle empty lists.

Output LOG file (code_example.log):

API Reference

def calculate_total(items):
    """Calculate the total price."""
    return sum(item.price for item in items)

Warning: This function does not handle empty lists.

Example 3: Tables and Lists

Frequently Asked Questions (FAQ)

Q: What is the difference between RST and LOG formats?

A: RST (reStructuredText) is a markup language with special syntax for headers, formatting, code blocks, and directives. LOG is plain text with no markup. Converting RST to LOG removes all markup syntax and leaves only the readable text content.

Q: Will I lose information when converting to LOG?

A: You will lose formatting information (bold, italic), structural markup, and hyperlinks. However, the actual text content is preserved. Code blocks are kept as plain text, and the logical structure is maintained through indentation and line breaks.

Q: Can I convert LOG back to RST?

A: Not automatically. Since LOG files don't contain markup information, there's no way to automatically restore the original RST formatting. You would need to manually add RST markup to the plain text content.

Q: What's the best use case for LOG files?

A: LOG files are ideal for text extraction, search indexing, content archiving, data processing pipelines, and any situation where you need clean text without markup. They're also useful for creating simple, readable backups of documentation.

Q: How are RST directives handled in the conversion?

A: Directives like note, warning, and code-block are converted to simple text labels. For example, ".. note::" becomes "Note:" and the content follows. Code blocks are preserved as plain text with their original indentation.

Q: What encoding is used for LOG files?

A: The output LOG files use UTF-8 encoding by default, which supports all Unicode characters. This ensures that special characters, non-English text, and symbols from your RST documents are preserved correctly.

Q: Can I process LOG files with command-line tools?

A: Absolutely! LOG files work perfectly with grep for searching, awk for text processing, sed for find-and-replace, wc for word counting, and any other text processing tool. This is one of the main advantages of the format.

Q: How are images and external references handled?

A: Images cannot be included in plain text, so image directives are converted to text references indicating the image path or alt text. External references and hyperlinks are converted to plain text, with the URL shown in parentheses when applicable.
