[Play 2.3.8] If condition bring line feed in scala template

Hi all,

I am facing issue with if conditions in scala template. In the following circumstance, the html will have white spaces and line breaks in between the two divs.

<div>
    content in previous div.
</div>
@if(condition) {
    <div>
        content in next div
    </div>

}

Another solution that may work is to allow any whitespace to go between the keyword and the brace.

Here is an example of how I want to use Twirl:

baseEmail.scala.txt

@(givenName: String)(content: Txt)
Hi @givenName,

@content

Thanks

newAccountEmail.scala.txt

@(givenName: String, admin: Boolean, url: String)
@baseEmail(givenName) {
@if(admin) {
An administrator account has been created for you.

Once you have activated your account, you can create accounts for other users in your organization.
} else {
An account has been created for you.
}

Use the link below to set the a password and activate your account.

Set password: @url
}

The current workaround:

newAccountEmail.scala.txt

@(givenName: String, admin: Boolean, url: String)
@baseEmail(givenName) {@if(admin) {An administrator account has been created for you.

Once you have activated your account, you can create accounts for other users in your organization.} else {An account has been created for you.}

Use the link below to set the a password and activate your account.

Set password: @url}

If braces could go on the following line it would be a little bit better:

newAccountEmail.scala.txt

@(givenName: String, admin: Boolean, url: String)
@baseEmail(givenName)
{@if(admin)
{An administrator account has been created for you.

Once you have activated your account, you can create accounts for other users in your organization.}
else
{An account has been created for you.}

Use the link below to set the a password and activate your account.

Set password: @url}

Ideal solution would be to have some kind of directive that allows the whitespace stripping from lines that only contain tags. At least this would be backwards compatible. Something like: @setting(settings.stripTagLines, true)

This makes Twirl impractical for plain text templating, say for example when you have both HTML and plain text emails.

I quite like having the template separate from my code.

I think the approach that Freemarker takes with whitespace stripping and an additional compress directive is pretty good and solves the simple cases.
