Mote
====
Minimum Operational Template.
Description
-----------
Mote is a very simple and fast template engine.
Usage
-----
Usage is very similar to that of ERB:
```ruby
template = Mote.parse("This is a template")
template.call #=> "This is a template"
```
Silly example, you may say, and I would agree. What follows is a short list of
the different use cases you may face:
```
% # This is a comment
% if user == "Bruno"
{{user}} rhymes with Piano
% elsif user == "Brutus"
{{user}} rhymes with Opus
% end
# Multiline code evaluation
lucky = [1, 3, 7, 9, 13, 15]
prime = [2, 3, 5, 7, 11, 13]
?>
{{ lucky & prime }}
```
## Control flow
Lines that start with `%` are evaluated as Ruby code. Anything between
`` and `?>`, including new lines, is also evaluated as Ruby code.
## Assignment
Whatever it is between `{{` and `}}` gets printed in the template.
## Comments
There's nothing special about comments, it's just a `#` inside your Ruby code:
```
% # This is a comment.
```
## Block evaluation
As with control instructions, it happens naturally:
```
% 3.times do |i|
{{i}}
% end
```
## Parameters
The values passed to the template are available as local variables:
```ruby
example = Mote.parse("Hello {{name}}", self, [:name])
assert_equal "Hello world", example.call(name: "world")
assert_equal "Hello Bruno", example.call(name: "Bruno")
```
Please note that the keys in the parameters hash must be symbols.
# Helpers
There's a helper available in the `Mote::Helpers` module, and you are
free to include it in your code. To do it, just type:
```ruby
include Mote::Helpers
```
### Using the mote helper
The `mote` helper receives a file name and a hash and returns the rendered
version of its content. The compiled template is cached for subsequent calls.
```ruby
assert_equal "***\n", mote("test/basic.mote", n: 3)
```
### Template caching
When the `mote` helper is first called with a template name, the
file is read and parsed, and a proc is created and stored in the
current thread. The parameters passed are defined as local
variables in the template. If you want to provide more parameters
once the template was cached, you won't be able to access the
values as local variables, but you can always access the `params`
hash.
For example:
```ruby
# First call
mote("foo.mote", a: 1, b: 2)
```
## Command line tool
Mote ships with a command line tool to render mote templates. The
result is redirected to standard output.
```
mote FILE [param1 value1 ... paramN valueN]
```
The extra parameters supplied will be passed to the template.
Note that all the parameter values will be treated as strings.
### Example usage
If your template is called foo.mote, you can render it with the
following command:
mote foo.mote
To write the result to a new file, just redirect the output:
mote foo.mote > foo.html
If the template uses a local variable `bar`, you can pass a
value from the command line:
mote foo.mote bar 42
## Installation
You can install it using rubygems.
```
$ gem install mote
```
