SequenceDiagram
1.0.0
一种用于从域特异性语言创建序列图的工具。在nodejs和浏览器中运行。
在在线编辑中看到它
核心渲染能力也可以作为库提供：
npm install --save svg-sequence-diagram import { SequenceDiagram } from 'svg-sequence-diagram' ;
const myDiagram = new SequenceDiagram ( `
title Foo
A -> B
B -> A
` ) ;
document . body . appendChild ( myDiagram . dom ( ) ) ;请参阅此处以获取完整的API文档。
或从命令行生成SVG：
npx svg-sequence-diagram < source.txt > diagram.svg
title Labyrinth
Bowie -> Goblin: You remind me of the babe
Goblin -> Bowie: What babe?
Bowie -> Goblin: The babe with the power
Goblin -> Bowie: What power?
note right of Bowie, Goblin: Most people get muddled here!
Bowie -> Goblin: "The power of voodoo"
Goblin -> Bowie: "Who-do?"
Bowie -> Goblin: You do!
Goblin -> Bowie: Do what?
Bowie -> Goblin: Remind me of the babe!
Bowie -> Audience: Sings

title Connection Types
begin Foo, Bar, Baz
Foo -> Bar: Simple arrow
Bar --> Baz: Dashed arrow
Foo <- Bar: Reversed arrow
Bar <-- Baz: Reversed & dashed
Foo <-> Bar: Double arrow
Bar <--> Baz: Double dashed arrow
# An arrow with no label:
Foo -> Bar
Bar ->> Baz: Different arrow
Foo <<--> Bar: Mix of arrows
Bar -> Bar: Bar talks to itself
Foo -> +Bar: Foo asks Bar
-Bar --> Foo: and Bar replies
Bar -x Baz: Lost message
# Arrows leaving on the left and right of the diagram
[ -> Foo: From the left
[ <- Foo: To the left
Foo -> ]: To the right
Foo <- ]: From the right
[ ~> ]: Wavy left to right!
# (etc.)
title Dividers
begin Foo, Bar, Baz
Foo -> +Bar
divider
Bar -> +Baz
divider delay: This takes a while
-Baz --> Bar
divider tear with height 20: Lots of stuff happens
-Bar --> Foo
title Note Placements
begin Foo, Bar
note over Foo: Foo says something
note left of Foo: Stuff
note right of Bar: More stuff
note over Foo, Bar: "Foo and Bar
on multiple lines"
note between Foo, Bar: Link
# in long diagrams, we can add reminders of which agent is which:
relabel
text right: "CommentsnOver here!"
state over Foo: Foo is ponderous
title At the Bank
begin Person, ATM, Bank
Person -> ATM: Request money
ATM -> Bank: Check funds
if fraud detected
Bank -> Police: "Get 'em!"
Police -> Person: "You're nicked"
end Police
else if sufficient funds
ATM -> Bank: Withdraw funds
repeat until "all requested money
has been handed over"
ATM -> Person: Dispense note
end
else
ATM -> Person: Error
end
autolabel "[<inc>] <label>"
begin "UnderpantsnGnomes" as A
A <- ]: Collect underpants
A <-> ]: ???
A <- ]: Profit!
title "My Multiline
Title"
begin Foo, Bar
note over Foo: "Also possiblenwith escapes"
Foo -> Bar: "Lines of textnon this arrow"
if "Even multilineninside conditions like this"
Foo -> "Multilinenagent"
end
state over Foo: "Newlines here,
too!"

title Mockup
A thing -> +Another thing: Something happens
-Another thing --> A thing: With some response
note right of Another thing: Find out what happens here
end Another thing
title "Baz doesn't live long"
note over Foo, Bar: Using begin / end
begin Baz
Bar -> Baz
Baz -> Foo
end Baz
note over Foo, Bar: Using * / !
# * and ! cause agents to be
# created and destroyed inline
Bar -> *Baz: make Baz
Foo <- !Baz: end Baz
# Foo and Bar end with black bars
terminators bar
# (options are: box, bar, cross, fade, none)
define My complicated agent name as A
define "Another agent name,
and this one's multi-line!" as B
A -> B: this is much easier
A <- B: than writing the whole name
define "Name with
**bold** and _italic_" as A
define "Also `code`
and ~strikeout~" as B
A -> B: "_**basic markdown
is supported!**_"
define Baz, Foo
Foo -> Bar
Bar -> Baz
begin User, Application, PostgreSQL
User -> +Application
Application -> +PostgreSQL
-PostgreSQL --> Application
-Application --> User
User is a person
PostgreSQL is a database
begin Initiator as I, Receiver as R
# the '...id' syntax allows connections
# to span multiple lines
I -> ...fin1
...fin1 -> R: FIN
# they can even inter-mix!
R -> ...ack1
R -> ...fin2
...ack1 -> I: ACK
...fin2 -> I: FIN
!I -> ...ack2
...ack2 -> !R: ACK
这是一个正在进行的功能。在某些情况下，这可能会导致丑陋 /不可读的重叠内容。
begin A, B, C, D
A -> C
# Define a marker which can be returned to later
some primary process:
A -> B
B -> A
A -> B
B -> A
# Return to the defined marker
# (should be interpreted as no-higher-then the marker; may be
# pushed down to keep relative action ordering consistent)
simultaneously with some primary process:
C -> D
D -> C
end D
C -> A
# The marker name is optional; using "simultaneously:" with no
# marker will jump to the top of the entire sequence.
评论以#开头，然后在下一个newline结束：
# This is a comment
可以使用特定关键字提供元数据：
title "My title here"
引用字符串通常是可选的，例如，它们是相同的：
title "My title here"
title My title here
title "My title" here
title "My" "title" "here"
每个非米达塔线代表顺序的序列中的一个步骤。
# Draw an arrow from agent "Foo Bar" to agent "Zig Zag" with a label:
# (implicitly creates the agents if they do not already exist)
Foo Bar -> Zig Zag: Do a thing
# With quotes, this is the same as:
"Foo Bar" -> "Zig Zag": "Do a thing"
围绕步骤的块，可以筑巢：
if something
Foo -> Bar
else if something else
Foo -> Baz
if more stuff
Baz -> Zig
end
end
（缩进被忽略）
