Supports

Use a variable like {{identifier}} in the markdown file. The utility parse code or comment with the same identifier, and replace it in markdown. The default code file we search are: java, kotlin, xml (for Android), swift, m, mm, c and cpp.

Sample code

Sample is the comments in code. When detected, it extract the source and don't change the format.

Line Comment

// SAMPLE: abc
code ...
// SAMPLE

the code between SAMPLE are assign to variable "abc".

Inline Comment

code line // SAMPLE: abc

This inline commnet usaully for single line comment.

Block Comment

unused /* SAMPLE: abc */ want /* SAMPLE */ blabla

This block comment used for some samll code. ** Not Recommend **.

XML Comment

Support extract part of xml lines.

<!--SAMPLE:abc-->
<class_list>
  <key>data</key>
</class_list>
<!--SAMPLE-->

Here use xml comment.

API document

This keyword is used to generate API table like https://ant.design/components/button-cn#api.

The comment format must be /// METHOD: class_name.method_name or /// ATTRIBUT: class_name.attribute_name.

After process all the input file, it will merge all method or attribut with same class name into a table.

Table in markdown file use the identifier {{METHOD:class_name}} or {{ATTRIBUT:class_name}}.

  frame: CGRect,
  text: String? = nil,

func createFullName(firstname:String, lastname:String)->String { 
    return "\(firstname)\(lastname)"
}

*/
