fix(url_decode): keep %2B as a literal plus when decoding - #939
Merged
Conversation
url_decode decoded the percent-encoding first and only then replaced "+" with a space, so a "%2B" became "+" and was immediately turned into a space. Any literal "+" was therefore lost when round-tripped through url_encode. I now replace "+" with a space before decodeURIComponent, which lines up with Ruby's CGI.unescape used by Shopify.

I noticed that
url_decodeloses a literal+:{{ "1%2B1" | url_decode }}gives1 1instead of1+1, and anything with a+no longer survives aurl_encode | url_decoderound-trip (a+b ccomes back asa b c).The cause is ordering: it ran
decodeURIComponentfirst and only then replaced every+with a space, so a%2Bdecoded to+and was immediately turned into a space. I moved the+-to-space replacement ahead ofdecodeURIComponent, so encoded pluses survive. This matches Ruby'sCGI.unescapethat Shopify uses.Tested with two new cases in
test/integration/filters/url.spec.ts(the%2Bdecode and the round-trip), plus the full suite and lint.
