Now you'd better resort to constructing https://github.com/posthtml/posthtml-expressions#conditionaltags. In the future, I'll see what can be done for such expressions. Thank you for bringing this to our attention.
Thanks. I already saw conditional tags, however it's messed to do this for every variable, like html dir attribute, head title tag, several classes, etc.
Same as your other examples:
<body class="{{ bodyClass || 'default' }}">
Where 'default'
can be an empty string ''
in order to output <body class="">
.

Thanks for your reply. I have already try this, but this works only when bodyClass is defined, even empty.
When it's not defined, the output is like not compiled, example:
{{ bodyClass || 'default' }}
Or sometimes even there is error undefined variable.
Component:
<div class="{{ maybeUndefined || 'is undefined' }}">
{{ maybeUndefined || 'is undefined' }}
</div>
Usage:
<h1>test2</h1>
<include src="components/test.html"></include>
Output:
I found a way to handle this:
<body class="{{ typeof bodyClass !== 'undefined' ? bodyClass : 'default' }}">
Suppose we have a variable for set body class. In case we don't pass any variable as body class I get
class="undefined"
How to check if variable is set?
