RST(reStructuredText)

GISBox is a one-stop 3D GIS data editing, conversion and publishing platform that supports editing in multiple GIS formats such as OSGB/GEOTIFF/RVT, converting to 3DTiles/Terrain and publishing.

Introduction

RST file, or reStructuredText file, is a lightweight markup language that uses simple markup syntax to write documents. It was first created and developed by David Goodger in 2002 and is mainly used for document writing and formatting. RST files usually have the extension “.rst” and use some specific symbols and structures to represent the various parts of the document, such as titles, lists, links, references, etc.

File Structure

RST (reStructuredText) file is a text file format that uses simple markup syntax to write documents. It is widely used to write technical documents, software description files, reports, etc. The RST file structure is mainly composed of the following basic elements:

Paragraphs: The text content in RST documents is usually organized in the form of paragraphs, and paragraphs are separated by blank lines. Paragraphs can contain normal text, inline formatted text (such as bold, italics, etc.), and other RST elements (such as links, references, etc.).
**Title: **RST documents support multi-level headers to organize the structure and hierarchy of documents. Headings are usually marked with underscores or equal signs, and the number indicates the level of the header. For example, a single underscore indicates a first-level header, a double underscore indicates a second-level header, and so on.
List: RST documents support unordered lists and ordered lists. Unordered lists use a hyphen (-) or an asterisk (*) as the prefix of list items, while ordered lists use numbers plus periods (1., 2., 3.) as the prefix of list items. List items can contain paragraphs, other lists, or inline formatted text, etc.
Code blocks: RST documents support embedded code blocks for displaying code examples or scripts. Code blocks are usually marked with specific syntax, such as “.. code-block::” followed by the programming language name to specify the language type of the code block. The text inside the code block will remain displayed as is without formatting.
Other elements: In addition to the basic elements mentioned above, RST documents also support many other elements, such as tables, images, hyperlinks, comments, etc. These elements are marked and organized by specific syntax rules, making the document structure clearer and easier to read.

Pros

1. Easy to read: The syntax of RST files is relatively simple, easy to learn and use.

2. Rich formats: RST files support a variety of text formatting functions, such as titles, lists, code blocks, etc., making the document structure clear and easy to read.

3. Strong convertibility: RST documents can be converted into multiple formats, such as HTML, PDF, etc., using tools such as Sphinx, which is convenient for publishing and sharing on different platforms.

Cons

1. Relatively niche: Although RST files have certain applications in software development and document writing, their popularity and scope of use are relatively small compared to other lightweight markup languages such as Markdown.

2. Learning cost: Although the syntax of RST files is relatively simple, it still takes some time for beginners to become familiar with and master it.

Application Scenario

RST files are widely used in software development, especially for writing README files, user manuals, developer guides, etc. This file format supports embedding code blocks, tables, lists, hyperlinks, and other content, making it very suitable for writing detailed technical documents. In the software development process, RST files can be used in conjunction with tools such as Sphinx to automatically generate code documents.
