diagrams.mbt for Python
diagrams.mbt renders Mermaid diagrams to standalone SVG in your Python
process. It uses the diagrams.mbt
MoonBit renderer, compiled to native code. It needs no browser, no Node.js and
no subprocess.
Experimental (0.0.x). The API can change in any release.
Install
pip install diagrams.mbt
Wheels are available for CPython 3.12 and later on:
| Platform | Wheel tag |
|---|---|
| Linux x86_64, glibc 2.17 or later | manylinux_2_17_x86_64 |
| Linux aarch64, glibc 2.17 or later | manylinux_2_17_aarch64 |
| macOS 11 or later, Apple silicon | macosx_11_0_arm64 |
| macOS 11 or later, Intel | macosx_11_0_x86_64 |
| Windows x86_64 | win_amd64 |
Free-threaded CPython builds are not supported.
Render a diagram
import diagrams_mbt
result = diagrams_mbt.render_svg("""
flowchart TD
A[Start] --> B{Ready?}
B -->|Yes| C[Render]
""")
if result.ok:
with open("diagram.svg", "w", encoding="utf-8") as f:
f.write(result.output)
render_svg returns a Rendered value with output (the SVG text or None),
media_type and diagnostics. It does not raise an exception for a diagram
error:
result = diagrams_mbt.render_svg("flowchart TD\n A[ --> B\n")
print(result.ok) # False
for d in result.diagnostics:
print(d.severity, d.code, d.message, d.span)
Supported Mermaid diagrams: flowchart and graph, sequence, state, ZenUML,
architecture-beta and swimlane-beta.
Notes
- Diagnostic columns and offsets count UTF-16 code units. Use
diagrams_mbt.code_point_index(source, offset)to get a Python string index. - Calls hold the GIL and run one at a time.
- An internal renderer failure (a MoonBit panic) stops the process. Do not render untrusted input in a process that must not stop.
