# ProcessPiper (Business Process Diagram as Code)
ProcessPiper is an open source python library to generate business process diagram using python code or [PiperFlow](https://github.com/csgoh/processpiper/wiki/Usage-Documentation#syntax) syntax.
## Method 1: Generate business process diagram using English like PiperFlow syntax
This is a sample code to generate a business process diagram using [PiperFlow](https://github.com/csgoh/processpiper/wiki/Usage-Documentation#syntax) syntax.
```python
from processpiper.text2diagram import render
input_syntax = """
title: Sample Test Process
colourtheme: BLUEMOUNTAIN
lane: End User
(start) as start
[Enter Keyword] as enter_keyword
(end) as end
pool: System Search
lane: Database System
[Login] as login
[Search Records] as search_records
as result_found
[Display Result] as display_result
[Logout] as logout
lane: Log System
[Log Error] as log_error
start->login: User \\nAuthenticate
login->enter_keyword: Authenticated
enter_keyword->search_records: Search Criteria
search_records->result_found: Result
result_found->display_result: Yes
display_result->logout->end
result_found->log_error: No
log_error->display_result
footer: Generated by ProcessPiper
"""
render(input_syntax, "my_process_map.png")
```
### Method 2: Generate business process diagram using Python code
This is a sample code to generate a business process diagram using Python code. The code is self-explanatory. The diagram is generated using the default colour theme.
```python
from processpiper import ProcessMap, EventType, ActivityType, GatewayType
with ProcessMap(
"Sample Test Process", colour_theme="BLUEMOUNTAIN") as my_process_map:
with my_process_map.add_lane("End User") as lane1:
start = lane1.add_element("Start", EventType.START)
enter_keyword = lane1.add_element("Enter Keyword", ActivityType.TASK)
with my_process_map.add_pool("System Search") as pool1:
with pool1.add_lane("Database System") as lane2:
login = lane2.add_element("Login", ActivityType.TASK)
search_records = lane2.add_element("Search Records", ActivityType.TASK)
result_found = lane2.add_element("Result Found?", GatewayType.EXCLUSIVE)
display_result = lane2.add_element("Display Result", ActivityType.TASK)
logout = lane2.add_element("Logout", ActivityType.TASK)
end = lane2.add_element("End", EventType.END)
with pool1.add_lane("Log System") as lane3:
log_error = lane3.add_element("Log Error", ActivityType.TASK)
start.connect(login, "User \nAuthenticates").connect(
enter_keyword, "Authenticated"
).connect(search_records, "Search Criteria")
search_records.connect(result_found, "Result").connect(display_result, "Yes")
display_result.connect(logout).connect(end)
result_found.connect(log_error, "No").connect(display_result)
my_process_map.set_footer("Generated by ProcessPiper")
my_process_map.draw()
my_process_map.save("my_process_map.png")
```
The generated diagram is as follows:

## Frontend Application
Two frontend applications have been developed to showcase ProcessPiper capability.
* [Piperoni](https://github.com/csgoh/Piperoni) - A desktop application
* [Piperita](https://piperita.streamlit.app/) - A Streamlit web application
## Support and Community
ProcessPiper is still in the early days of development, if you have any problem, I will try my best to resolve it.
