Suppressing EOL / whitespace

[finanalyst]

Use case: I need to have one set of HMTL if data is present, another if absent.
From the documentation, the only way I can do this as follows (note the disambiguation to ensure only the Hash key is tested)

<div id="<.name>">
<?.<tail>><.tail></?>
<!.<tail>>No tail</!>
</div>

HTML is produced as expected BUT there is always an extra line added in, either one corresponding to the <!....> stanza not generating a string, or the <?.... not generating a string.

HTML renderers remove whitespace, so it does not have an impact on users, but I find it difficult when developing and debugging HTML if there is excessive whitespace.

Is there a way to suppress whitespace?

Is there a better way in Crotmp to get alternate rendering depending on a boolean test?

Yes, any line that only contains a conditional or iteration related tag will not introduce whitespace. Thus if you instead write:

<div id="<.name>">
<?.<tail>>
<.tail>
</?>
<!.<tail>>
No tail
</!>
</div>

Then you'll not get the blank lines.

Not implemented yet, but the plan is that a <!>...</!> that immediately follows a positive conditional tag will do that. So it would be:

<div id="<.name>">
<?.<tail>>
<.tail>
</?>
<!>
No tail
</!>
</div>
