2. Plain text
RestructuredText, at its foundation, relies on plain text. The relationship is fundamental: the “what does rst mean” operates directly on plain text files. This means that the source document consists of standard characters, devoid of proprietary formatting or binary encoding. The absence of such encoding allows for platform independence; an RST document can be created, edited, and rendered on any operating system or text editor. The advantage here is that the user is not locked into a specific software application or file format, which is a consideration when working with documentation intended to last for years.
The use of plain text as the source format allows for version control using standard software development tools like Git. Because the files are text-based, diffs are easily generated and reviewed, making collaboration and tracking changes straightforward. In contrast to binary formats, which are opaque to these tools, plain text enables a clear and auditable history of changes. Consider a large software project where multiple developers are contributing to the documentation; the plain text nature of RST allows for easy merging of contributions, conflict resolution, and tracking the evolution of the documentation over time. This is not readily achievable with proprietary word processing formats. Furthermore, RST files can be readily processed by automated tools, further increasing the value of utilizing a plain text source format.
In summary, the reliance on plain text is not merely a characteristic of RST; it is a core enabler of its versatility, portability, and suitability for professional documentation. The simplicity of plain text unlocks the benefits of version control, automated processing, and platform independence, all of which contribute to its value in creating and maintaining high-quality documentation.
