It provides is able to render slides from a deck, described in Markdown.\n\n## Markdown Format\n\nThe markdown format follows the style of markdown used by [Remark](https://github.com/gnab/remark). There are limitations to what can be handled by the parser and renderer, and there are some extensions.\n\n### Slide delimiting and styles\n\nSlides are separated by the horizontal rule marker (`---`). The slide separator may be immediately\nfollowed by properties which should be applied to this (and subsequent) slides. The properties take the form of colon-separated key-value pairs, which give the property name and its value. Properties may be deleted by prefixing their name with a single `-` character.\n\nThe following properties are defined:\n\n* `name`: Declares a name for this slide (used by the templates)\n* `template`: Declares the slide name which should be used as the basis for this slide - must be the first property of the slide. The templates only take property information from the templated slide.\n* `background-colour`/`foreground-colour`: Changes the slide background and text foreground colour. It is not currently possible to change the colour of text inline. Colours may be named CSS colours, `#RRGGBB`, `#RGB`, `rgb(r,g,b)` or `rgb(r%,g%,b%)` values (as supported by the WebColours module).\n* `*.font`/`*.size`/`*.height`: Defines font characteristics for the main styles used within the slides. Each font name may be suffixed by `.bold` and `.italic` (in that order) to configure specific font styles. The size and height are only configurable on the base font at the current time. The following font names may be defined:\n    * `body`\n    * `h1`, `h2`, `h3`\n    * `code`\n    * `quote`\n    * `marginal`\n* `h#.padding.top`/`h#.padding.bottom`/`h#.padding.inset`: Defines the padding at the top and the bottom of the headings, and the inset for the text in the heading.\n* `vertical-align`: Alignment of the slide content, which may take the value `top`, `middle`, or `bottom`.\n* `padding`/`padding-horizontal`/`padding-vertical`: Defines the size of the slide padding.\n* `list.padding.top`/`list.padding.bottom`: Defines the space around lists.\n* `item.padding.top`/`item.padding.bottom`: Defines the space around each list item.\n* `item.padding.inset`: Defines the inset horizontally of each list item's text (or bullet).\n* `item.padding.offset`: Defines the offset horizontally from the inset point to the text of the item's body.\n* `pre.padding.inset`: Defines the inset horizontally that the preformatted text blocks use\n* `pre.padding.inside`: Defines the space between the border and the content of the preformatted text.\n* `pre.border.width`: Defines the width of the border around preformatted text.\n* `pre.border.type`: Defines the type of border placed around the preformatted region, which can take the following values:\n    * `none`: No border.\n    * `solid`: Single colour, solid border.\n    * `double`: Two borders, each with width 1/3 of the set width.\n    * `inset`: A 3D effect, sunk into the region (light top left).\n    * `outset`: A 3D effect, raised from the region (light top left).\n    * `ridge`: A 3D effect, a ridge around the region (light top left).\n    * `groove`: A 3D effect, a sunken groove around the region (light top left).\n* `pre.border.background-colour`: Defines the colour of the background, or `none` to not use any\n* `pre.border.colour`: Defines the colour of the border, or `none` to not use any\n* `pre.border.fore-colour`: Defines the colour of the 3D effect fore colour, or `none` to not use any\n* `pre.border.opposite-colour`: Defines the colour of the 3D effect opposite colour, or `none` to not use any\n* `quote.padding.top`/`quote.padding.bottom`: Defines the space around a block quote\n* `quote.padding.inset`: Defines the inset horizontally of the block quote to the quote bar.\n* `quote.padding.offset`: Defines the offset horizontally from the inset point to the text of the block quote's body.\n* `quote.bar.width`: Defines the width of the quote bar.\n* `quote.bar.colour`: Defines the colour of the quote bar.\n* `logo.POSITION`: Defines an image to place in a given position (see below)\n* `logo.POSITION.inset`: Defines the gap around the outside of the image to leave.\n* `logo.POSITION.width`/`logo.POSITION.height`: Defines the width/height of the image (which will be limited by the size of the slide)\n* `slidenumber.position`: defines a position for the slide number label on each slide, where the position value can be any of the position specifications (or `none` to remove the slide number).\n* `slidenumber.padding`: defines the spacing from the edge of the screen for the slide number.\n* `slidenumber.format`: defines how the slide number is printed as a string. `$s` is replaced by the slide number, and `$m` by the maximum slider number.\n\n### Position specifications\n\nPositions are used for a few of the properties. The following positions are defined:\n\n* `top-left`\n* `top`\n* `top-right`\n* `left`\n* `centre`\n* `right`\n* `bottom-left`\n* `bottom`\n* `bottom-right`\n\n### Size specifications\n\nSizes can be in pixels (which corresponds to 2 OS units, even in EX0/EY0 modes) or with size specifications:\n\n* `#pt`: In points (effectively 1 pixels at present)\n* `#pc`: In picas, which are 12 points.\n* `#px`: Explicitly in pixels (which remain 2 OS units)\n* `#in`: In inches, which are 72 pixels.\n* `#cm`: In centimetres, which are 28.3125 pixels.\n* `#em`: In multiples of the 'em' size of the plain base font in the slide; the size will differ in the x and y dimentions.\n* `#%`: In multiples of the space available; the size will differ in the x and y dimentions. Because the size depends on the context in which it is used, this percentage may be relative to two spaces:\n    * the slide space, for content which is global to the slide\n    * the remaining space in a block, for content which is inline with the body of the slide\n\nSizes may be specified as floating point values.\n\n### Supported markdown\n\nThe markdown supported is in line with most implementations but is limited - the [MD4C](https://github.com/mity/md4c) library is used as the back end parser. The following elements of markdown are supported:\n\n* Heading levels 1-3 indicated by lines prefixed by `#`, `##`, `###`.\n* Inline code indicated by being surrounded by backticks.\n* Italic, indicated by `*` surrounding text.\n* Underline, indicated by `_` surrounding text.\n* Bold, indicated by `**` surrounding text.\n* Bold and italic, indicated by `***` surrounding text.\n* Strikethrough, indicated by `~` surrounding text.\n* Ordered lists, indicated by a line starting with a `1.` (or other digit sequence), which may be indented to indicate nesting levels.\n* Unordered lists, indicated by a line starting with a `*` or `-`, which may be indented to indicate nesting levels.\n* Block quotes, indicated by a line starting with a `\u003e`.\n* Code blocks delimited by three backticks.\n\nThe encoding used for rendering is the default alphabet (no specific alphabet is selected by the Font system at the current time).\n\n### Unsupported markdown\n\nAny features not documented above are not supported, though partial support may exist within the system. Non-exhaustively, the following are not supported:\n\n* Tables in any form.\n* Wiki links and task lists.\n* HTML blocks.\n* Latex maths specifications.\n* HTML entities.\n* Nested quote blocks don't work as expected.\n\nThe incremental slide format (two hyphens, `--`) used by Remark is not supported by the tool.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgerph%2Friscos-presenter","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgerph%2Friscos-presenter","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgerph%2Friscos-presenter/lists"}
