对python实现模板生成脚本的方法详解

最近项目需要，针对主项目提取一个小的基础版本，供于在新建项目时使用，所以就有这个

最近项目需要，针对主项目提取一个小的基础版本，供于在新建项目时使用，所以就有这个python模板生成脚本，其作用如下：

1、通过配置文件来控制模板中的数据、格式化的过滤条件

2、执行后会把目录下所有的文件都会执行一篇

#!/usr/bin/python
#encoding: utf-8
 
import json
import codecs
import os
 
def get_files(root_path):
 for dir in os.walk(root_path):
 if dir[2]:
 for nf in dir[2]:
 yield os.path.join(dir[0], nf)
 
def exclude_filter(exclude, nfile):
 files_path = exclude.get('file_path')
 files_name = exclude.get('file_name')
 base_name = os.path.basename(nfile)
 exts_name = exclude.get('ext_name')
 base_ext_name = base_name.rsplit(".", 1)[1]
 if files_path:
 for npath in files_path:
 if npath==nfile:
 return True
 elif files_name:
 for name in files_name:
 print name, base_name
 if name==base_name:
 return True
 elif exts_name:
 for name in exts_name:
 print name, base_ext_name
 if name==base_ext_name:
 return True
 
def include_filter(include, nfile):
 files_path = include.get('file_path')
 files_name = include.get('file_name')
 base_name = os.path.basename(nfile)
 if files_path:
 for npath in files_path:
 if npath==nfile:
 return True
 elif files_name:
 for name in files_name:
 if name==base_name:
 return True
 
def main():
 # read config
 config = {}
 with codecs.open("config.json","rb","UTF-8") as f:
 config = json.loads(f.read())
 if not config:
 return
 
 template = config.get("template")
 if template and template.get('path'):
 root_path = template.get('path')
 if not os.path.exists(root_path):
 print "source path not exist"
 return
 root_path = os.path.abspath(root_path)
 old_path = os.path.dirname(root_path)
 else:
 return
 exclude = template.get('exclude')
 include = template.get('include')
 
 store = config.get("store")
 if not store or not os.path.exists(store.get('dir_path', '')):
 return
 
 data = config.get("data")
 if not data:
 return
 
 if not os.path.exists(root_path):
 print 'root path not exists'
 return
 
 if os.path.isfile(root_path):
 files = [root_path]
 else:
 base_name = os.path.basename(root_path)
 store_root_path = os.path.join(store.get('dir_path'), base_name)
 if not os.path.exists(store_root_path):
 os.mkdir(store_root_path)
 files = get_files(root_path)
 
 for nfile in files:
 print nfile
 try:
 with codecs.open(nfile, "rb", "UTF-8") as f:
 s = f.read()
 
 if not exclude_filter(exclude, nfile) or include_filter(include, nfile):
 s = s % data
 except:
 with codecs.open(nfile, "rb") as f:
 s = f.read()
 
 # save to file
 fn = nfile.replace(old_path, store.get('dir_path'))
 fn_dir = os.path.dirname(fn)
 if not os.path.exists(fn_dir):
 os.makedirs(fn_dir)
 try:
 with codecs.open(fn, "wb", "UTF-8") as f:
 f.write(s)
 f.flush()
 except:
 with codecs.open(fn, "wb") as f:
 f.write(s)
 f.flush()
 
if __name__ == '__main__':
 main()

配置文件：

{
 "template": {
 "path" : "D:/tunicorn-web/framework-template", ##模板文件主目录
 "exclude" : { ##不进行模板格式化的文件
 "file_path" : [], 
 "file_name" : ["config.json", "make_project.py"], 
 "ext_name" : ["css", "woff2"],
 "file_type" : [],
 "regex" : []
 },
 "include" : { ##进行模板格式化的文件
 "file_path" : [],
 "file_name" : []
 }
 },
 "store":{
 "dir_path" : "e:/test" ##输出路径主目录 
 "data" : {
 "project_name":"NewJAVA", ##模板数据
 "project_prefix":"newjava" ##模板数据
 }
}

执行操作：

1、安装了python环境

2、双击python脚本

3、然后在执行下README中的步骤

readme：

README =============

脚本使用 ------------- 1. 打开config.json文件 2. 配置相关信息[输出目录、项目名称、项目前缀] 3. 执行make_project.py脚本 4. 查看输出目录
