Browserslist-rs Gets Major Refactor, Cutting Binary Size by Over 1MB
Browserslist-rs now uses static data to reduce binary size by over 1MB, improving memory use and performance for Rust-based frontend tools.
Based on the pipe library, adding more utilities and pipes to it
Some pipes are inspired by other programming languages (eg Rust)
pip install morepipes
Consume iterable
range(9) | where(lambda x: x % 2) | collect
# List of odd numbers
Cut iterables
range(9) | take(5) | drop(2) | collect
# [2, 3, 4]
Remove duplicates
a = [1, 3, 3, 1, 2, 4, 4, 2, 2, 2, 1, 4, 4, 3, 3, 1]
b = a | squeeze | collect
# [1, 3, 1, 2, 4, 2, 1, 4, 3, 1], remove consecutive duplicates
c = b | unique | collect
# [1, 3, 2, 4]
Manipulate iterations
range(9) | chunks(4)
# [[0, 1, 2, 3], [4, 5, 6, 7]]
range(9) | alternate
# [0, 2, 4, 6, 8]
Side effects
range(9) | ... | inspect | ...
# Prints out each object received on evaluation
Or, more generally
range(9) | ... | foreach(print) | ...
There's also bindings for builtins and itertools
[1, 2, 3] | combinations(2)
[1, 2, 3] | permutations
[1, 2, 3] | cycle
[1, 2, 3] | imap(iseven)
[1, 2, 3] | isum # 6, equivalent to sum([1, 2, 3])
[1, 2, 3] | iall(iseven) # equivalent to all(iseven(x) for x in [1, 2, 3])
[1, 2, 3] | iany(iseven) # equivalent to any(iseven(x) for x in [1, 2, 3])
[1, 2, 3] | ilen # 3, equivalent to len([1, 2, 3])
isum
, iall
, iany
, ilen
is useful when working with long pipe chains (no messy parentheses)
Creating a partial pipe
reverse_sort = P | reverse | sort
# P is a special object placeholder
Using a partial pipe
[1, 3, 4, 2] | reverse_sort
# Just like any other pipe
# Strictly equivalent to:
[1, 3, 4, 2] | reverse | sort
# as if P is replaced by [1, 3, 4, 2]
Have fun!
