Convert Textile to INI

Why Convert Textile to INI?

Converting Textile to INI format is useful when you need to extract structured data from Textile documents and represent it as configuration settings. The conversion maps Textile headings to INI sections and extracts key-value pairs from the document content, creating a machine-readable configuration file from human-authored markup.

Textile, created by Dean Allen in 2002, is a lightweight markup language with heading-based document structure (h1., h2., h3.). This hierarchical structure maps naturally to INI sections, where each heading becomes a section name enclosed in square brackets. Content within each section is parsed into key=value pairs based on the text patterns found in the Textile source.

INI (Initialization) files have been a cornerstone of software configuration since the MS-DOS era. Despite their simplicity, they remain widely used in modern applications: PHP uses php.ini, MySQL uses my.cnf (INI format), Git uses .gitconfig (INI format), and Python includes configparser in its standard library specifically for INI file handling. The format's strength lies in its extreme simplicity and human readability.

This conversion is particularly valuable when you have project documentation or configuration guides written in Textile format (such as Redmine wiki pages) and need to generate actual configuration files from the documented settings. It bridges the gap between human-readable documentation and machine-parseable configuration data.

Key Benefits of Converting Textile to INI:

• Documentation to Config: Generate config files from Textile documentation
• Section Mapping: Textile headings become INI sections naturally
• Universal Format: INI is supported by virtually all programming languages
• Human-Readable: Both source and output are easy to read and edit
• Simple Structure: Clean key=value pairs for application settings
• Redmine Integration: Convert Redmine wiki config docs to actual INI files
• Cross-Platform: INI files work on Windows, Linux, and macOS

Practical Examples

Example 1: Application Configuration

Input Textile file (config.textile):

h1. Application Settings

h2. Server

p. host = 0.0.0.0
port = 8080
workers = 4

h2. Database

p. engine = postgresql
host = localhost
port = 5432
name = production_db

Output INI file (config.ini):

[Server]
host = 0.0.0.0
port = 8080
workers = 4

[Database]
engine = postgresql
host = localhost
port = 5432
name = production_db

Example 2: Redmine Project Settings

Input Textile file (project.textile):

h1. Project Configuration

h2. General

p. name = MyProject
version = 2.1.0
author = Development Team

h2. Deployment

p. target = production
auto_deploy = true
notify_team = true

Output INI file (project.ini):

[General]
name = MyProject
version = 2.1.0
author = Development Team

[Deployment]
target = production
auto_deploy = true
notify_team = true

Example 3: Environment Setup

Input Textile file (env.textile):

h1. Environment Variables

h2. Logging

p. level = INFO
file = /var/log/app.log
max_size = 10MB

h2. Cache

p. backend = redis
host = 127.0.0.1
ttl = 3600

Output INI file (env.ini):

[Logging]
level = INFO
file = /var/log/app.log
max_size = 10MB

[Cache]
backend = redis
host = 127.0.0.1
ttl = 3600

Frequently Asked Questions (FAQ)

Q: What is INI format?

A: INI (Initialization) is a simple configuration file format consisting of sections (in square brackets) and key=value pairs. Originating from early MS-DOS and Windows systems, INI files are still widely used for application configuration. Examples include php.ini, my.cnf (MySQL), .gitconfig, and countless application settings files. The format is supported by all programming languages.

Q: What is Textile markup?

A: Textile is a lightweight markup language created by Dean Allen in 2002. It uses intuitive punctuation for formatting: *bold*, _italic_, h1. for headings, # for numbered lists, and pipe characters for tables. Textile is widely used in Redmine project management and Textpattern CMS, and it produces clean HTML output.

Q: How are Textile headings mapped to INI sections?

A: Textile headings (h1., h2., h3., etc.) are converted to INI section names enclosed in square brackets. For example, "h2. Database Settings" becomes "[Database Settings]" in the INI output. The content under each heading is parsed for key-value pairs that become the settings within that section.

Q: Does INI support nested sections?

A: No, standard INI format only supports a flat, single-level section structure. Unlike TOML or YAML, INI does not have nested sections or hierarchical data. If your Textile document has deeply nested headings, they will be flattened into separate INI sections. For hierarchical configuration data, consider converting to TOML, YAML, or JSON instead.

Q: What happens to Textile formatting (bold, italic) in INI?

A: Textile formatting markers like *bold* and _italic_ are stripped during conversion since INI is a plain-text configuration format that does not support text formatting. Only the actual content text and key-value data are preserved in the INI output. The focus is on extracting structured data, not visual formatting.

Q: Can I use the INI output in Python?

A: Yes! Python includes the configparser module in its standard library, which can read and write INI files. Simply use configparser.ConfigParser() to load your converted INI file and access settings as config['section']['key']. This makes it easy to use Textile-documented settings directly in your Python applications.

Q: Are comments supported in the INI output?

A: The INI format supports comments using semicolons (;) or hash marks (#) at the beginning of lines. While Textile does not have a direct comment syntax, any descriptive text in your Textile document that is not structured as key=value data may be included as INI comments, preserving context and documentation in the configuration file.

Q: How does INI compare to TOML and YAML for configuration?

A: INI is the simplest of the three: flat sections with key=value pairs, no data types, no nesting. TOML extends INI with data types, nested tables, and arrays while maintaining readability. YAML offers the most features including deep nesting, complex data structures, and references, but is more complex. INI is best for simple, flat configuration needs.
