A means to add an extension #46
Description
I often need to add an extension (be it .tmp or .bak for example).
Writing path.sub_ext("#{path.extname}.tmp") is weird. Likewise for path.sub(/\z/, '.tmp'). And unfortunately + and / have exactly the same semantics, so I can't use that either.
I wish I had add_ext.
Cheers!

You can do
Pathname("#{path}.tmp").akimd commentedon Dec 9, 2025
Hi,
Yes, of course, but it feels unnatural, and more importantly it breaks the chain of calls (including
/) by being "prefix" instead of suffix. It makes the result harder to read.eregon commentedon Dec 9, 2025
FWIW the path gem has add_ext.
