Could you please explain what the pipe (|) in tor specification means -- is it a bitwise or or a concatenation of the values?
Encoding onion addresses [ONIONADDRESS]
The onion address of a hidden service includes its identity public
key, a version field and a basic checksum. All this information is
then base32 encoded as shown below:
onion_address = base32(PUBKEY | CHECKSUM | VERSION) + ".onion"
CHECKSUM = H(".onion checksum" | PUBKEY | VERSION)[:2]
where:
PUBKEYis the 32 bytes ed25519 master pubkey of the hidden service.
VERSIONis an one byte version field (default value'x03')
".onion checksum"is a constant string
CHECKSUMis truncated to two bytes before inserting it inonion_address
From the context, I understand it is a concatenation-- is that so?
If one has a working short PythonNodeRuby snippet for that, it would be lovely. :)

As you suspect, it's a concatenation symbol. Some times it's $|$ and others $||$. Or $+$. Python and PL/SQL examples to confirm. Or a cryptographic example: bottom of page 5 of FIPS PUB 202: SHA-3 Standard: Permutation-Based Hash and
Extendable-Output Functions.
If it were bitwise OR, you'd make a real mess of the public key's use with PUBKEY | CHECKSUM | VERSION.
It can get weird though if you dig deeper as: Is there a common symbol for concatenating two (finite) sequences?
