## Usage
### Template
CANS provides robust support for templating, including support for handling HTML, looping through collections, and rendering text. Below are some examples demonstrating how to use the (`do_replace`, `do_html`, ``do_xml`, `do_json` macros, the `do_forloop`, and the `do_text` functions.
CANS provides robust support for templating, including handling various content types, looping through collections, and rendering text. Below are some examples demonstrating how to use the (`do_replace`, `do_html`, `do_xml`, `do_json`) macros, as well as the `do_forloop` and `do_text` functions.
The `do_replace` macro takes any content string or data (e.g., code, file content, templates) along with key-value pairs and replaces placeholders in the content (formatted as `{{key}}`) with the corresponding values. This macro is highly versatile and can manipulate any content of any programming language or file by substituting placeholders.
Macros for specific content types can be defined by wrapping `do_replace!`.
For example, to create a macro for CSS content:
```rust
// use cans::content::do_replace;
use cans::do_replace;
#[macro_export]
macro_rules! do_css {
($content:expr, $($key:ident = $val:expr),*) => {
$crate::do_replace!($content, $($key = $val),*)
};
}
```
Now, `do_css!` can be used to easily replace placeholders in CSS templates.
### Example: Using the do_html Macro
```rust
use cans::content::{do_html, do_text, alpine};
pub const HEAD: &str = r#"<head>
<meta charset="UTF-8">
{{alpinejs}}
<title>{{page_title}} Page</title>
</head>"#;
pub const HOME_TEMPLATE: &str = r#"<!DOCTYPE html>
<html>
{{HEAD}}
<body>
<h1>Home Page</h1>
<div x-data="{ open: false }">
<button x-show="!open" @click="open = true">Show</button>
<button x-show="open" @click="open = false">Hide</button>
<span x-show="open">
CANS template with Alpine.js
</span>
</div>
</body>
</html>"#;
pub fn do_home_page() -> String {
// Alpine version, e.g., "3.15.0" or "latest" for the most recent version.
do_html!(HOME_TEMPLATE, HEAD = HEAD, alpinejs = alpine("latest"), page_title = do_text("Home"))
}
pub const ABOUT_TEMPLATE: &str = r#"<!DOCTYPE html>
<html>
{{HEAD}}
<body>
<h1>About Page</h1>
<p>
{{component_if}}
</p>
<div x-data="{ count: 0 }">
<button x-on:click="count--">Decrement</button>
<span x-text="count"></span>
<button x-on:click="count++">Increment</button>
</div>
</body>
</html>"#;
pub fn do_about_page() -> String {
let component_if: &str;
let x = 3;
if x == 1 {
component_if = "<a href='#'><i>x = 1</i></a>";
} else if x == 2 {
component_if = r#"<a href='#'><i>x = {{x}}</i></a>"#;
} else {
component_if = "<a href=\"#\"><i>x ≠ 1 & x ≠ 2. The 'x' value is ( {{x}} )</i></a>";
};
do_html!(
ABOUT_TEMPLATE,
HEAD = HEAD,
// Alpine version "3.10.0"
alpinejs = alpine("3.10.0"),
page_title = do_text("About"),
component_if = component_if,
x = x // x must be defined after component_if.
)
}
fn main() {
let home_page = do_home_page();
println!("{}", home_page);
let about_page = do_about_page();
println!("{}", about_page);
}
```
```html
<!-- home page output -->

</body>
</html>
```
### Example: Using the do_forloop Function
```rust
use cans::content::do_forloop;
fn main() {
let items = vec!["Apple", "Banana", "Cherry"];
let list_html = do_forloop(&items, "<ul>", "<li>", "</li>", "</ul>");
println!("{}", list_html);
// Output: <ul><li>Apple</li><li>Banana</li><li>Cherry</li></ul>
let float_vector = vec![1.0, 2.0, 3.0];
let forloop_float = do_forloop(&float_vector, "", "", "", "");
println!("{}", forloop_float);
// Output: 123
}
```
### Example: Using the do_xml macro
```rust
// use cans::content::do_xml;
use cans::do_xml;
let xml_content = "<note><to>{{recipient}}</to></note>";
let xml_result = do_xml!(xml_content, recipient = "Ahmed");
assert_eq!(xml_result, "<note><to>Ahmed</to></note>");
```
### Example: Using the do_json macro
```rust
// use cans::content::do_json;
use cans::do_json;
let json_content = r##"{"greeting": "{{greeting}}", "name": "{{name}}"}"##;
let json_result = do_json!(json_content, greeting = "Hi", name = "Ahmed");
assert_eq!(json_result, r##"{"greeting": "Hi", "name": "Ahmed"}"##);
```
### MIME Module
The **MIME** module in the `cans` crate provides functionalities for handling MIME types, which are essential for identifying and processing various types of files, such as HTML documents, images, and multimedia content. This module facilitates the identification, validation, and management of different MIME types used across the web, providing features such as:
- **MIME Type Detection**: Automatically determine the MIME type of a file based on its extension or content.
- **Type Validation**: Check if a specific MIME type is valid.
- **Extension Retrieval**: Retrieve file extensions associated with given MIME types.
- **Custom MIME Types**: Register and manage custom MIME types to suit specific requirements.
```rust
use cans::mime::{
display_mime_types,
insert_mime_types,
manage_mime_types,
remove_mime_types,
set_mime_types
};
fn main() {
// Create a new HashMap and initialize it with default MIME types
let mut mime_types = set_mime_types();
println!("Initial MIME types:");
display_mime_types(&mime_types);
// Display the default count of MIME types
println!("The default length of MIME types: {}", mime_types.len()); // Example output: 113
// Define an array of tuples for both already included and new MIME types
let included_mime_types = manage_mime_types(&[
// Already included MIME types
("html", "text/html"),
("css", "text/css"),
("js", "application/javascript"),
("svg", "image/svg+xml"),
("gif", "image/gif"),
("jpg", "image/jpeg"),
("txt", "text/plain"),
("json", "application/json"),
// New MIME type to include
("some_ext", "some_mime"),
]);
// Insert new MIME types into the existing HashMap
insert_mime_types(&mut mime_types, included_mime_types);
// Display the length after insertion
println!(
"The length after inserting MIME types: {}",
mime_types.len() // Example output: 114
);
// Display the updated MIME types
println!("\nAfter inserting MIME types:");
display_mime_types(&mime_types);
// Define an array of tuples for both pre-existing and new MIME types
let excluded_mime_types = manage_mime_types(&[
// Pre-existing MIME types by default
("html", "text/html"),
("css", "text/css"),
("js", "application/javascript"),
("svg", "image/svg+xml"),
("gif", "image/gif"),
("jpg", "image/jpeg"),
("txt", "text/plain"),
("json", "application/json"),
// New MIME type that is not part of the default list
("some_ext", "some_mime"),
]);
// Attempt to remove MIME types from the existing HashMap
remove_mime_types(&mut mime_types, excluded_mime_types);
// Display the length after removal
println!(
"The length after removing MIME types: {}",
mime_types.len() // Example output: 105
);
// Display the updated MIME types
println!("\nAfter removing MIME types:");
display_mime_types(&mime_types);
}
```
### World Module
A module that encapsulates the management of country details, including functionalities for inserting, deleting, retrieving, and sorting countries. Additionally, it provides features for managing city information within those countries, enabling users to insert, delete, retrieve, and sort city details. This comprehensive management system allows for seamless interaction between countries and their respective cities, facilitating efficient access to geographical and administrative data. Users can efficiently reset the dataset to accommodate new data for testing purposes. The module promotes data integrity and optimal memory management through precise control over entries. It allows for easy querying and manipulation of country and city information to support various applications.
