100% agree R needs native fstrings. I don’t use {glue} (for various reasons) and work quite a bit in JS these days, and really miss that feature in R.

I have been embracing python as the same time as posit. uv and ruff have been welcoming for my r background. There are things I like such as unpacking and fstrings that I wish r has.

c2y release notes:
- printf now starts a Python interpreter to parse fstrings (internal implementation only)
- MSVC now considered a D compiler
- added more undefined behavior

I’m in no way a coder but when I came across fstrings I felt an aesthetic objection. It seems such a language hack (though useful it seems)

C++ is a lot nicer with variable interpolating fstrings and the ability to concisely test cross products of flow control.

It's performance-driven. FNames are auto-hashed and meant to be used for lookups. FTexts are localizable and optimized for presentation retrieval. FStrings are general purpose for convenient buffer lifetimes/manipulation.

Although glue has no dependency, I have also not been using it because I feel like fstrings should be baked into base r. sprintf does most of it but we need native fstrings. Hope R 5.0 would give us that.

this python book i've got came out last year, apparently, and i just ctrl+f'd "fstring" and got absolutely no results.
if this book expects me to use fucking string concatenation and shit I will find another book, fstrings came out in python 3.6, which was like, 2016!

Python fstrings are apparently interpreted and executed in-situ and render as strings, meaning string ops and methods can be performed on them.

apparently, I'm 'quirky'* because:

Yeah, that's what I've been using, it's just a lot less flexible than fstrings.

people who still use "".format() instead of fstrings in python 3 are perverts who will not see the kingdom of heaven

we just use formatted sql files, but you could probably do the same w/fstrings. e.g.
template.sql
SELECT *
FROM schema.table
WHERE {filter_expression}
script.py
(
open('template.sql')
.read()
.format(
filter_expression='value = 1'
)
)
template.sql
SELECT *
FROM schema.table
WHERE {filter_expression}
script.py
(
open('template.sql')
.read()
.format(
filter_expression='value = 1'
)
)
