Latex-cv-gen is a latex cv generator that uses Jinja2 for templating. It allows the user to generate se-resume (but really any latex cv if you provide your own template) using a json or yaml (also yml) file containing contents to be generated as the cv.
If the user provides a json file, the file is validated against a schema that includes everything that's expected in the json body. At the moment of writing this, all fields are mandatory. A less stringent measure is applied if a yaml file is supplied instead and no schema validation is done.
