engkheng	dbbc340f25	Validate `input_variables` when using `jinja2` templates (#3140) ... `langchain.prompts.PromptTemplate` and `langchain.prompts.FewShotPromptTemplate` do not validate `input_variables` when initialized as `jinja2` template. ```python # Using langchain v0.0.144 template = """"\ Your variable: {{ foo }} {% if bar %} You just set bar boolean variable to true {% endif %} """ # Missing variable, should raise ValueError prompt_template = PromptTemplate(template=template, input_variables=["bar"], template_format="jinja2", validate_template=True) # Extra variable, should raise ValueError prompt_template = PromptTemplate(template=template, input_variables=["bar", "foo", "extra", "thing"], template_format="jinja2", validate_template=True) ```	1 year ago
engkheng	19febc77d6	Support inference of `input_variables` from `jinja2` template (#3013) ... `langchain.prompts.PromptTemplate` is unable to infer `input_variables` from jinja2 template. ```python # Using langchain v0.0.141 template_string = """\ Hello world Your variable: {{ var }} {# This will not get rendered #} {% if verbose %} Congrats! You just turned on verbose mode and got extra messages! {% endif %} """ template = PromptTemplate.from_template(template_string, template_format="jinja2") print(template.input_variables) # Output ['# This will not get rendered #', '% endif %', '% if verbose %'] ``` --------- Co-authored-by: engkheng <ongengkheng929@example.com>	1 year ago
