DESCRIPTION

The Markdown file hook provides a editing environment for Markdown files. The file hook provides highlighting, folding of section, document outline using item-list and abbreviations. Fenced code blocks within triple backticks can be highlighted using the declared code block language.

File recognition is performed using the standard file extension .md, .tmd, .rmd or .qd. The .qd file extension is reserved for Quarkdown files which provided a few more highlightings for quaurkdown commands at the beginning of a line starting with a dot.

Abbreviations


The installation comes with a default abbreviation file for Markdown code editing which can be used by writing short abbreviations like "h1" for a default level 1 header, "bo" for bold text, "url" for an URL, or "cc" for a code chunk - and then pressing the key-binding for the expand-abbrev-handle(3) command. The list of abbreviations can be used interactively in the GUI version of MicroEmacs using the abbrev-list(3) command.

Folding and Information Hiding


Generic folding is enabled within the Markdown files. The folds occur about the level 2 headers, so headers with two hash symbols at the beginning of a line. The following commands are supported to show and hide the function bodies. collapse-all(3) (un)folds all regions in the file, collapse-current(3) (un)folds the current region.

List Items


Item listing is available and the level 1 and 2 headers of the file are displayed in the item-list.

Short Cuts


The short cut keys used within the buffer are:

C-c C-c - Comment out the current line.
C-c C-d - Uncomment the current line.
f2 - (un)fold the current region
f3 - (un)fold all regions
f6 - list items
esc f6 - close list items

Code Chunk Highlighting


Inside code chunks as well syntax hilghlighting for a few programming languages like Tcl (tcl), R (r), GraphViz Dot (dot), Python (py), SQL (sql), MicroEmacs macro code (emf)or Javascript (js) is available. Here an example which should be highlighted within a Markdown file using the R file hook:

```{r} 
x = 1 
test = function () { 
    print("Test") 
} 
```
