Enhancement proposal

Hello,

It would be nice to have an option in Spyder which, when turned on, detect when '{' or '}' are written in string. It would then add a 'f' in front of the string in order to set up a formatted string.

Hope to see this feature in Spyder one day.

Thanks for your amazing work !

Thanks for reporting. We'll take a look at this in a future release.

@ccordoba12 Isn't adding new substantive enhancements now frozen after 3.3.0? Or has that changed?

[ccordoba12]

@dalthviz, please work on this one.

Hi,
I'm currently using Spyder version 4.2.1 and I noticed f-strings are not supported.
More specifically, there is not syntax highlighting in the editor, see screen capture below:

Compared to atom:

Is this feature coming to future versions ?

I am using Spyder 5.2.1 and f-strings are still not highlighted in editor.

For example code:

classname = "title"
html1 = f'''<h1 class="{classname}">Hello, world!</h1>'''
classname = ["title","title-default"]
html2 = f'''<h1 class="{" ".join(classname)}">Hello, world!</h1>'''

could look something like:

Instead it's all green as mentioned in previous comments.
Example code is valid python3.6:

>>> html1
'<h1 class="title">Hello, world!</h1>'
>>> html2
'<h1 class="title title-default">Hello, world!</h1>'

This functionality will come in Spyder 6 because it requires that we integrate with a new syntax highlighting library.

Im on Spyder 6 and it looks like it still isnt working. Is this feature expected?

Hi @Knarf224 this is indeed over the backlog/list of features to be implemented for Spyder 6. To be more specific, for the moment, the idea is to have this available for Spyder 6.2.0 (current latest release for Spyder 6 is 6.0.4). Also, although this prioritization can change in the future, if the issue is still open definetly is something we will try to check in a future release!
