Flowchart PHP

Flowchart PHP is a proof of concept tool that allows you to generate explanatory diagrams directly from your PHP source code.
This tool is designed to improve the documentation for your application and help users better understand component interactions in large codebases.
With Flowchart PHP, you can quickly and easily create diagrams that illustrate the flow of your code, making it easier to understand and debug.
Whether you're a developer working on a complex application or a technical writer looking for a better way to explain complex concepts, Flowchart PHP can help you create clear, concise, and visually appealing diagrams that will enhance your documentation and improve the overall user experience.

Why ?

• Huge callstacks visualizations are not informative containing too much code noise.
• Sometimes components include async operations running is different processes that can't be visualized by just using call stack
• This tool is aiming to simplify code flow visualization

Requirements

1. php >= 8.1
2. nodejs
3. puppeteer along with chrome
4. mmdc for node

Mermaid chart example that was injected automatically into this readme.md

%%[FlowchartGlobal]
flowchart LR;
registry["Records Registry"]
exporter["Exporter Composite"]
exporter--"finds records by namespace"-->registry
GenerateCommand["Generate Command"]
GenerateCommand--"1. calls collector"-->collector
GenerateCommand--"2. calls exporter"-->exporter
collector["Collector"]
scannedDir["Scanned Directory"]
collector--"scans attributes"-->scannedDir
scannedDir--"receives attributes"-->collector
collector--"register records"-->registry

Usage

Use PHP attributes to mark your code with nodes and their links withing chart namespace to describe interaction

#[
    \Flowchart\Node('collector', 'Collector'),
    \Flowchart\Node('scannedDir', 'Scanned Directory'),
    \Flowchart\Link('collector', 'scannedDir', 'scans attributes'),
    \Flowchart\Link('scannedDir', 'collector', 'receives attributes'),
    \Flowchart\Link('collector', 'registry', 'register records')
]
class Collector

Define root chart namespaces configs and/or dedicated configuration by placing .flowchart.json file chart namespace root folder.
Specify chart exports config for given folder tree.
Use destination -> exporter type\

{
  "namespace": "FlowchartGlobal",
  "exports": {
    "./../README.md": "md",
    "customFile.txt": "text",
    "FlowchartGlobal.png": "png"
  }
}

Currently, the app supports:

• generating raw text file that can be visualized at https://mermaid.live/edit
• generating png files (node mmdc along with puppeteer packages required)
• injecting source text into .md files via specifying %%[CHART_NAMESPACE]
• more exporters for Confluence, Wiki etc. are coming soon.

The package can be extended with custom exporters to provide more flexible usage

Generate charts for own codebase

bin/flowchart generate ./src

Generate output images via JS from collected mermaid charts

mmdc -i ./src/FlowchartGlobal.mmd -o out.png -p puppeteerConfigFile.json
