Generate a sequence diagram from a text description and save as PNG.

from seqdiag import parser, builder, drawer import codecs # Read a .seqdiag file (or use a string) diagram_text = """ seqdiag { A -> B [label = "request"]; B -> A [label = "response"]; } """ tree = parser.parse_string(diagram_text) diagram = builder.ScreenNodeBuilder.build(tree) drawer.draw(diagram, 'output.png', 'PNG')

seqdiag --version

Debug

Known issues

breakingIn seqdiag 3.0.0, the API changed: parser.parse_string() is the canonical way; the old top-level functions are gone.

fix

Use seqdiag.parser.parse_string() instead of the deprecated top-level seqdiag.parse().

affects: <=2.x

gotchaThe seqdiag command-line tool requires the font configuration to be set correctly. Without it, generated images may lack text.

fix

Install fonts or set environment variable BLOCKDIAG_FONT_PATH.

affects: all
