about Apostrophe

In the next article we are going to take a look at Apostrophe. This is a free and open source Markdown editor for Gnu / Linux. It is a distraction-free editor with a minimal and clean interface. The program has a preview function. This function will format the markdown commands automatically.

Some other important features are previewing images, links, footnotes, equations, and exporting the markdown document to a file. It also comes in light / dark mode, focus mode, spell checking, document statistics, and more than 18 languages ​​supported.

In Apostrophe we will be able to configure up to five different variants of Markdown. These are; Github-flavored Markdown, Pandoc Markdown, MultiMarkdown, CommonMark and Plain Markdown. Supports full-width, half-width, half-height, and windowed views. It will also allow us to synchronize views and automatically hide the header bar. This program uses pandoc as a backend for Markdown analysis and offers a very clean and elegant user interface with which you can work very comfortably.

In case there is still someone who does not know, say that markdown is a plain text format syntax, which was created by John Gruber in 2004. This language offers the benefits of plain text, and provides a convenient format for writing on the web, but is not intended to replace HTML. Markdown is a write format, not a post format.
