rendertpl

rendertpl is a command-line utility designed for rendering template files. It takes a template file, often containing placeholder variables and control structures, and processes it to produce a final output file. The primary function of rendertpl is to dynamically generate text-based content by substituting variables with specific values. This is commonly used in software development for tasks such as generating configuration files, code snippets, or documentation.

The typical workflow involves providing rendertpl with a template file and a set of data, usually in a structured format like JSON or YAML. The utility then parses the template, identifies the placeholders and logic, and uses the provided data to populate these elements. For instance, a template might include a variable like `{{ .username }}` which would be replaced by the actual username from the data source during rendering. Control structures can also be employed, allowing for conditional logic or loops within the template to create more complex and dynamic outputs.

rendertpl supports various templating languages, though its core functionality often revolves around a specific syntax. The output of rendertpl can be redirected to standard output or saved directly to a file. This makes it a flexible tool for automation scripts and build processes where dynamic content generation is a requirement. Its simplicity and focus on template rendering make it a useful addition to a developer's toolkit for streamlining repetitive content creation tasks.
