mould - A minimalistic templating engine for Python

This Python library helps to render HTML pages and plain text with variable substitutions, if conditions and for loops.

Templating syntax :

To delcare variables enclose the variable name with '{{ ' and ' }}'

Hello {{ text }} -- 'text' is the variable here

You can use the same syntax to write variable expressions.

This is line number {{ n+10 }}

if conditional

Use '{% ' and ' %}' to enclose the lines where an if block starts and use the same with 'endif' keyword for closing the if blocks

{% if 5 < 6  %}
Hello world!
{% endif %}

Variables can also be used to write if conditions. Inside the conditional statement, the variables can be written as such. The enclosing syntax mentioned above is not required.

{% if x > y %}
Hello Python!
{% endif %}

if block supports 'else' and 'elif' as well.

{% if x > y %}
Hello X!
{% elif z > x %}
Hello Z!
{% else %}
Hello ABC!
{% endif %}

for loop

Use '{% ' and ' %}' to enclose the lines where a 'for' block starts and use the same with 'endfor' keyword for closing the 'for' blocks

{% for n in numbers %}
This is line {{ n }} printed using for loop
{% endfor %}

In the above code, 'n' and 'numbers' are variables where 'n' is the looping variable and 'numbers' is the list on whose items, the loop is run.

for supports looping over lists, strings and dictionaries

How to install:

You can get this from PyPI using pip

pip install mould

Alternatively, you can get it from git also using pip.

pip install https://github.com/ramk95/mould-it/archive/refs/heads/master.zip

How to use:

Import the library to your python program

import mould

Call the mould.it() function with your input file / input text along with a dictionary of variables that you have used in your text / input file

mould.it(input_text, variables_dictionary)

This will return the rendered output. You can either print it direclty or save it.

print(mould.it(input_text, variables_dictionary))

or

rendered_data = mould.it(input_text, variables_dictionary)

Dependencies:

mould uses python standard libraries io and os. No other dependent packages are required.

Example:

    import mould

    input = "Hello {{ var }}"
    variables = {"var" : "world !"}

    print(mould.it(input,variables))



    Output:
    Hello world !
