template

A template processor.

Install

Install with pip:

pip install 'git+https://github.com/paiv/template-py'

Usage

import template
template.format(text, context=None, varchar='&', /, **kwargs)

The only substitution is of & variables in the form:

• &name
• &{name}

Basic substitution:

template.format('&v &{v}', v='hello')
'hello hello'

If a value is not provided, the variable will not be substituted.

template.format('&v &s, &{v} &{s}', v='hello')
'hello &s, hello &{s}'

Environment can be provided in a dictionary:

context = dict(v='hello')
template.format('&v &{v}', context)
'hello hello'

Environment values can be of the types:

• str - simple string
• generator - a generator of strings
• callable - a function returning str or a generator
• any other type will be converted to str

The leading character of variables can be changed:

template.format('#v #{v}', None, '#', v='hello')
'hello hello'

Example

import template

def gen():
    yield 'alice\n'
    yield 'bob\n'

context = dict()
context['data'] = gen

tpl = '''
Greetings,
  &data
'''

template.format(tpl, context)
'''
Greetings,
  alice
  bob
'''
