A Python package for generating Jinja2 templates
Project description
j2_template
Introduction
This is a template for creating a new Jinja2 template.
实现了一个类似 Ansible 的 template 模块工具，具备以下功能：
- 渲染 Jinja2 模板。
- 支持命令行界面（CLI），可以通过传递模板文件、上下文、输出文件等参数来进行模板渲染。
- 支持
dry-run模式，避免实际输出文件，仅打印渲染结果。 - 支持通过 API 调用，能够将功能集成到其他 Python 项目中。
- 使用
argparse和logging模块来实现命令行参数解析和日志记录，确保工具的易用性和可调试性。
Usage
模版文件：template.j2
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>{{ title }}</title>
</head>
<body>
<h1>{{ greeting }}</h1>
<p>{{ description }}</p>
</body>
</html>
CLI 模式：
#从文件读取模板和上下文数据：
j2_template --template-file template.j2 --context-file context.json
j2_template --template-file template.j2 --context-file context.json --log-level info
# 从标准输入读取模板内容：
cat template.j2 | j2_template --context '{"title": "Test", "greeting": "Hello!", "description": "This is a description."}' --output result.txt --log-level debug
# 使用环境变量提供上下文数据：
export J2_TEMPLATE_CONTEXT='{"title": "Test", "greeting": "Hello!", "description": "This is a description."}'
j2_template --template-file template.j2 --output result.txt
API 模式：
from j2_template import render_template
# 示例上下文
context = {
'title': 'Test Page',
'greeting': 'Hello, World!',
'description': 'This is a Jinja2 template rendered in Python.'
}
# 渲染模板并输出到控制台
render_template(template_file='test/test_template.html', context=context)
