[jira] Issue Comment Edited: (TAPESTRY-2028) Mimimize whitespace in
the output markup
[ https://issues.apache.org/jira/browse/TAPESTRY-2028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12557400#action_12557400 ]

What actually prompted this? I don't require the whitespace for rendering anywhere (at least that I know of -- this isn't going to be a fun way to find out), but just about any other debugging issue is going to be terrible. Looking at the source before it's processed doesn't always help because one may not know how any components or their IDs will render until they do so.
I can empathize with the performance of the parser, but this really seems to be too invasive of an operation for a framework to be performing. As for client speed, the whitespace issue was solved a long time ago via gzip compression. I'd rather see Tapestry include a gzip filter that's enabled by default than this approach.

> Project: Tapestry
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.0.7
> Reporter: Howard M. Lewis Ship
> Assignee: Howard M. Lewis Ship
> Fix For: 5.0.8
>
>
> Tapestry (4 and 5) has traditionally honored all the white space in a template. This is for a few specific cases, such as text inside a <pre> element (who uses those?).
> This results in output documents that, due to the extra whitespace that often surrounds Tapestry components, contain large amounts of whitespace.
> In most cases, interior white space (whitespace between text characters) can be reduced to a single space, and white space just after a tag or just before a tag can be eliminated entirely.
> The Tapestry template parser should honor the xml:space attribute and use it to determine what template whitespace is relevant, and what whitespace may be minimized or eliminated.
