# Directives
|
|
Each directive begins with an `@` sign.
|
|
Some directives begin contains a `{}` block, others only have `''` (string) parameters.
|
|
More on the directives itself.
|
|
|
|
Newlines on the beginning and end are ignored in `{}` blocks,
|
|
otherwise this (see [if](##if) for this syntax):
|
|
```html
|
|
@if bool_val {
|
|
<span>This is shown if bool_val is true</span>
|
|
}
|
|
```
|
|
would result in:
|
|
```html
|
|
|
|
<span>This is shown if bool_val is true</span>
|
|
|
|
```
|
|
which could result in unreadable output.
|
|
|
|
## if
|
|
The if directive consists of three parts, the `@if` tag, the condition (same syntax like in V)
|
|
and the `{}` block where you can write html which will be rendered if the condition is true:
|
|
```
|
|
@if <condition> {}
|
|
```
|
|
|
|
### Example
|
|
```html
|
|
@if bool_val {
|
|
<span>This is shown if bool_val is true</span>
|
|
}
|
|
```
|
|
One-liner:
|
|
```html
|
|
@if bool_val { <span>This is shown if bool_val is true</span> }
|
|
```
|
|
|
|
The first example would result in:
|
|
```html
|
|
<span>This is shown if bool_val is true</span>
|
|
```
|
|
while the one-liner results in:
|
|
```html
|
|
<span>This is shown if bool_val is true</span>
|
|
```
|
|
|
|
## for
|
|
The for directive consists of three parts, the `@for` tag, the condition (same syntax like in V)
|
|
and the `{}` block where you can write html which will be rendered for each loop:
|
|
```
|
|
@for <condition> {}
|
|
```
|
|
|
|
### Example
|
|
```html
|
|
@for i, val in my_vals {
|
|
<span>$i - $val</span>
|
|
}
|
|
```
|
|
One-liner:
|
|
```html
|
|
@for i, val in my_vals { <span>$i - $val</span> }
|
|
```
|
|
|
|
The first example would result in:
|
|
```html
|
|
<span>0 - "First"</span>
|
|
<span>1 - "Second"</span>
|
|
<span>2 - "Third"</span>
|
|
...
|
|
```
|
|
while the one-liner results in:
|
|
```html
|
|
<span>0 - "First"</span>
|
|
<span>1 - "Second"</span>
|
|
<span>2 - "Third"</span>
|
|
...
|
|
```
|
|
|
|
You can also write (and all other for condition syntaxes that are allowed in V):
|
|
```html
|
|
@for i = 0; i < 5; i++ {
|
|
<span>$i</span>
|
|
}
|
|
```
|
|
|
|
## include
|
|
The include directive is for including other html files (which will be processed as well)
|
|
and consists of two parts, the `@include` tag and a following `'<path>'` string.
|
|
The path parameter is relative to the `/templates` directory in the corresponding project.
|
|
|
|
### Example
|
|
Files
|
|
```
|
|
Project root
|
|
/templates
|
|
- index.html
|
|
/headers
|
|
- base.html
|
|
```
|
|
|
|
`index.html`
|
|
```html
|
|
<div>@include 'header/base'</div>
|
|
```
|
|
> Note that there shouldn't be a file suffix,
|
|
it is automatically appended and only allows `html` files.
|
|
|
|
# Variables
|
|
All variables which are declared before can be used through the `@{my_var}` syntax.
|
|
It's also possible to use properties of structs here like `@{my_struct.prop}`.
