YATLA 📑: Yet Another Templating Language (Again!)

YATLA is a templating engine with a simple templating language specifically designed for type inference, allowing consumers to provide users with slots of determined types.

Roadmap 🗺️

• Add numerical blocks
• Add type inference. Go from a template -> list of typed parameters
• Write own lexer to respect whitespace
• Write own own parsing system
• Add template validation (preventing non-unique identifiers...)
• Publish as pip-installable package
• Add foreach loops
• Add numerical function calls
• Improve Python interface
• Think about object accessors

Sample Template

This sample template gives a whirlwind tour of YATLA's functionality.

This a sample template.

This line contains a {{ slot }}.

Slots can also contain mathematical expressions: {{ 3 + factor * 7 }}.
With full support for operator precedence: {{ (3 + factor) * 7 }}.

Foreach loops are also valid. For example:

This is the {{ factor }} times table:
{{ foreach num in num_list }}
    {{ factor }} * {{ num }} = {{ factor * num }}
{{ endforeach }}

There is also a standard library of mathematical functions.
Comparing {{ factor }} and {{ num }}, the largest is {{ Maximum(factor, num) }} and the smallest is {{ Minimum(factor, num) }}.
{{ RoundUp(15, 2) }} = 16, and {{ RoundDown(15, 2) }} = 14. 

From the template above, YATLA will identify the parameters in the template, and infer their types:

• slot: string or number
• factor: number
• num: number
• num_list: number array
