print does not work as expected

[qingyunha]

In branch 2.0. I run the example of docstring

from __future__ import unicode_literals
from prompt_toolkit import print
from prompt_toolkit.styles import Style

style = Style.from_dict({
    'hello': '#ff0066',
    'world': '#884444 italic',
})
fragments = [
('class:hello', 'Hello'),
('class:world', 'World'),
]
print(fragments, style=style)

output

[('class:hello', 'Hello'), ('class:world', 'World')]

But when I commented the two lines， it work

 66     # Merges values.
 67     def to_text(val):
 68         # if isinstance(val, list):
 69             # return to_formatted_text('{0}'.format(val))
 70         return to_formatted_text(val, auto_convert=True)

Thanks for reporting! The documentation is wrong. The fragments list needs to be wrapped into a FormattedText object.

Originally, this wasn't the case, but I changed it that way, because I wanted to be compatible with the Python print function.

@jonathanslenders is there a good way to print formatted text in such a way that it gets put above the prompt? Using the patch_stdout function, I can work with the normal printing, but I haven't figured out how to do formatted printing.

Hi @benhoff,
Sorry for the late reply. Right now, if you pass raw=True to patch_stdout, then it should work:

edit: I guess we can probably come up with a cleaner solution in the future.

@jonathanslenders
No worries, I got pulled off onto something else. Is there a good way to find out if this gets added/merged?
Changelog? Documentation?

I'll probably pull back onto using this in a couple of months so it's no worries, just trying to figure out the best way to re-engage.
