SVG Metadata: Space between hyphens

0 votes
asked May 8, 2020 in Bug by coxley

When extracting the metadata from an SVG diagram, there are spaces in between the hyphens. Rendering the result fails, making metadata not identical.

Example: http://www.plantuml.com/plantuml/uml/~1UDfrpp4EmZ0CGD7Tf_058i70WaZLTcFj3PnYgPPIfoJEmkaHZLXGsP_qzQ4lHjdg6W6ynxkA2KLvaKbIz1w0gYMjQ-0CGvIPqNKufd35eTh2QZ8tE_6pSZ4OKq3dEjpnWIfRqi9xRUADJGvAU3xXvJUdoHREICVPXc_EDKt_z3VVipu-rs-GkLSn

Output:

<SVG data>

<!--MD5=[99c473cf1763466ab516dfa997550731]
@startuml

== Initialization ==

autonumber
Alice -> Bob: Authentication Request
Bob - -> Alice: Authentication Response

== Repetition ==

autonumber 10 5
Alice -> Bob: Another authentication Request
Alice <- - Bob: another authentication Response

Hello Coxley,

You can see this first answer (of @plantuml) on another report about this fact:

"The main issue is that the diagram code is put into a svg comment. Separator for SVG comment are <!-- and --> so spaces are added to prevent clash between the diagram definition itself and the SVG comment separators.

We cannot do much about this. Any suggestion is welcome !"

From:

Depending of the current implementation of putting plantuml image source code in comment tag on the svg:

If that can help,
Regard,
