module main
    ## Description
    
    This is an example of a an .md file, used for adding more rich text documentation in a project or module.
    
    This is a [link](https://vlang.io/) to the main V site.
    
    This is a <b>bold text</b>.
    
    This is a script `<script>console.log('hi from README.md');</script>` .
    
    ## Examples
    
    ### Processing command line args
    
    ```v
    import os
    
    fn main() {
    	dump(os.args)
    	dump(os.args.len)
    	assert os.args.len > 0
    
    	// Test escape characters like for `&` and `<`
    	mut arr := [1, 2, 3]
    	mut ref := &arr
    	arr << 4
    
    	ch := chan bool{cap: 1}
    	ch <- true
    }
    ```
    
    ### A JWT example (test syntax highlighting)
    
    ```v
    import crypto.hmac
    import crypto.sha256
    import encoding.base64
    import json
    import time
    
    struct JwtHeader {
    	alg string
    	typ string
    }
    
    struct JwtPayload {
    	sub  string
    	name string
    	iat  int
    }
    
    fn main() {
    	sw := time.new_stopwatch()
    	secret := 'your-256-bit-secret'
    	token := make_token(secret)
    	ok := auth_verify(secret, token)
    	dt := sw.elapsed().microseconds()
    	println('token: ${token}')
    	println('auth_verify(secret, token): ${ok}')
    	println('Elapsed time: ${dt} uS')
    }
    
    fn make_token(secret string) string {
    	header := base64.url_encode(json.encode(JwtHeader{'HS256', 'JWT'}).bytes())
    	payload := base64.url_encode(json.encode(JwtPayload{'1234567890', 'John Doe', 1516239022}).bytes())
    	signature := base64.url_encode(hmac.new(secret.bytes(), '${header}.${payload}'.bytes(),
    		sha256.sum, sha256.block_size))
    	jwt := '${header}.${payload}.${signature}'
    	return jwt
    }
    
    fn auth_verify(secret string, token string) bool {
    	token_split := token.split('.')
    	signature_mirror := hmac.new(secret.bytes(), '${token_split[0]}.${token_split[1]}'.bytes(),
    		sha256.sum, sha256.block_size)
    	signature_from_token := base64.url_decode(token_split[2])
    	return hmac.equal(signature_from_token, signature_mirror)
    }
    ```
    
    ### Other language specifiers
    
    ```cpp
    #include <iostream>
    #include <map>
    
    std::map<std::string, int> my_map {
    	{"KEY_1", 0},
    	{"KEY_2", 10},
    };
    
    for (const auto &[key, value] : my_map) {
    	std::cout << key << ": " << value << ", ";
    }
    std::cout << "\n";
    ```
    
    ```v ignore
    doc1 := toml.parse_text(<string content>) or { panic(err) }
    doc2 := toml.parse_file(<file path>) or { panic(err) }
    ```
    
    ### Escape html in strings
    
    ```v
    const html = '<!DOCTYPE html>
    <html lang="en">
      <head>
        <style>
          body {
            background: linear-gradient(to right, #274060, #1B2845);
            color: GhostWhite;
            font-family: sans-serif;
            text-align: center;
          }
        </style>
      </head>
      <body>
        <h1>Your App Content!</h1>
        <button onclick="callV()">Call V!</button>
      </body>
      <script>
        async function callV() {
          // Call a V function that takes an argument and returns a value.
          const res = await window.my_v_func(\'Hello from JS!\');
          console.log(res);
        }
      </script>
    </html>'
    ```

fn MyXMLDocument.abc(text string) ?(string, int)
    MyXMLDocument.abc does something too... I just do not know what.
fn MyXMLDocument.from_file(path string) !MyXMLDocument
    MyXMLDocument.from_text processes the file path, and returns an error
fn MyXMLDocument.from_text(text string) ?MyXMLDocument
    MyXMLDocument.from_text processes text and produces none
struct MyXMLDocument {
	path string
}
    MyXMLDocument is here just to test the different combinations of methods/output types
fn (x &MyXMLDocument) instance_from_file(path string) !MyXMLDocument
    instance_from_file does stuff with path
fn (x &MyXMLDocument) instance_from_text(text string) ?MyXMLDocument
    instance_from_text does stuff with text
fn (x &MyXMLDocument) instance_abc(text string) ?(string, int)
    instance_abc does stuff too
fn (x &MyXMLDocument) instance_void()
    instance_void does stuff too
fn (x &MyXMLDocument) instance_int() int
    instance_int does stuff too
fn (x &MyXMLDocument) instance_result() !
    instance_error does stuff too
fn (x &MyXMLDocument) instance_option() ?
    instance_option does stuff too
