Marker

Marker is an open-source editor for Linux in the Photo & Graphics category. It supports code blocks with syntax highlighting, allowing code to be displayed with visual formatting inside edited documents. Users can apply custom syntax themes to change the appearance of highlighted code.

The editor includes an integrated sketch editor for creating sketches during the editing process. It also supports figure captions and numbering, which helps organize visual elements within documents. Custom CSS themes let users adjust the appearance of generated documents.

Marker is distributed through MirrorNest as the official Linux build. MirrorNest mirrors that build directly to its own storage and scans it for malware before publishing it. This places the official open-source software within MirrorNest’s Linux catalog and its Photo & Graphics category.
