Custom __pragma__ aliases or definitions

[kiwi0fruit]

Sometimes it's convenient to have a custom pragma aliases: #404 (comment)

Or may be it would also be useful to define something more complex than such aliases.

PS

This thought started here. So I guess that comments are no longer relevant.

Like

__pragma__('jsx', x)

means

__pragma__('xtrans', 'jsx-transform --factory React.createElement', '{}', x)

?

Even that the previous can now be written as:

__pragma__('xtrans', None, '{}', x)

When using the

transcrypt --xtrans="jsx-transform --factory React.createElement"

Command line switch it still looks not neat enough.

I just bumped into transcrypt and haven't used it yet but I found the potential to use JSX interesting, hence stumbled into this issue (along with preceding discussions).

Is there anything unique to __pragma__ stopping me from doing this?

def jsx(x): 
    return __pragma__('xtrans', 'jsx-transform --factory React.createElement', '{}', x)

Then in another module do

from pyreact import jsx
...

jsx(
    """
    <h1>Hello {world}!</h1>
    """
)
