Meta-language for DSL implementation inspired by Xtext
Project description
textx_model
介绍
以textX为基础构建出可运行条件规则语句然后输出结果的模型
条件规则语句(例):"(current_medical_program = '白细胞计数') and (specimen_type = '全血') and "
"(medicine_projects in '[1,2,3]') and (time < 6)"
-
当里面变量是:"current_medical_program = '白细胞计数';specimen_type = '全血';medicine_projects = '2';time = 5;"
结果输出: True
-
当里面变量是:"current_medical_program = '白细胞计数';specimen_type = '全血';medicine_projects = '2';time = 8;"
结果输出: False
功能介绍
包含两个模型:通用模型(general_model)和 case when 专用模型(cs_model),它们处理的条件规则语句不同。
包含一个工具:字典转字符串工具(dict_to_str)
-
通用模型
能处理的条件规则语句(例):"(current_medical_program = '白细胞计数') and (specimen_type = '全血') and "
"(medicine_projects in '[1,2,3]') and (time < 6)"使用通用模型: from textx_model import general_model
-
case when 专用模型
能处理的条件规则语句(例):"case when (current_medical_program = '白细胞计数') and (specimen_type = '全血') and "
"(medicine_projects in '[1,2,3]') and (time < 6) then '提醒消息:白细胞计数的消息' else ''"使用case when 专用模型
from textx_model import cs_model
-
字典转字符串工具
from textx_tools import dict_to_str
安装教程
- pip install textx-model
使用说明
-
通用模型
from textx_model import general_model
rule = "(current_medical_program = '白细胞计数') and (specimen_type = '全血') and "
"(medicine_projects in '[1,2,3]') and (time < 6)"true_example = "current_medical_program = '白细胞计数';specimen_type = '全血';medicine_projects = '2';time = 5;"
false_example = "current_medical_program = '白细胞计数';specimen_type = '全血';medicine_projects = '2';time = 8;"
gm = general_model(true_example, rule) print(gm.run()) # 预期结果:True
gm = general_model(false_example, rule) print(gm.run()) # 预期结果:False
-
case when 专用模型
from textx_model import cs_model
rule = "case when (current_medical_program = '白细胞计数') and (specimen_type = '全血') and "
"(medicine_projects in '[1,2,3]') and (time < 6) then '提醒消息:白细胞计数的消息' else ''"true_example = "current_medical_program = '白细胞计数';specimen_type = '全血';medicine_projects = '2';time = 5;"
false_example = "current_medical_program = '白细胞计数';specimen_type = '全血';medicine_projects = '2';time = 8;"
cs = cs_model(true_example, rule) print(cs.run()) # 预期结果:提醒消息:白细胞计数的消息
cs = cs_model(false_example, rule) print(cs.run()) # 预期结果:''
-
字典转字符串工具
from textx_tools import dict_to_str
data_dict = { 'current_medical_program': '白细胞计数', 'specimen_type': '全血', 'medicine_projects': '2', 'time': 8, '_list': [1, 2, 3] }
""" 预期结果: "current_medical_program = '白细胞计数';specimen_type = '全血';medicine_projects = '2';time = 8;_list = '[1,2,3]';" """
print(dict_to_str(data_dict))
