bech32 cli also support SP decoding.

v1.4.2 release

In this release, the contents of Segwit(witness version and witness program) and NIP19 entity are output in the output of the CLI decode command like follows:

v1.4.0 release

This release added support for decoding/encoding Nostr's NIP-19 entities.

It is possible to decode/encode NIP-19 entities as follows:

# Decode bare entity
bech32 = 'npub10elfcs4fr0l0r8af98jlmgdh9c8tcxjvz9qkw038js35mp4dma8qzvjptg'
entity = Bech32::Nostr::NIP19.parse(bech32)
entity.hrp
=> 'npub'
entity.data
=> '7e7e9c42a91bfef19fa929e5fda1b72e0ebc1a4c1141673e2794234d86addf4e'

# Decode tlv entity
bech32 = 'nprofile1qqsrhuxx8l9ex335q7he0f09aej04zpazpl0ne2cgukyawd24mayt8gpp4mhxue69uhhytnc9e3k7mgpz4mhxue69uhkg6nzv9ejuumpv34kytnrdaksjlyr9p'
entity = Bech32::Nostr::NIP19.parse(bech32)
entity.hrp
=> 'nprofile'
entity.entries[0].value
=> '3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d'
entity.entries[1].value
=> 'wss://r.x.com'

# Encode bare entity
entity = Bech32::Nostr::BareEntity.new('npub', '7e7e9c42a91bfef19fa929e5fda1b72e0ebc1a4c1141673e2794234d86addf4e')
entity.encode
=> 'npub10elfcs4fr0l0r8af98jlmgdh9c8tcxjvz9qkw038js35mp4dma8qzvjptg'

# Encode tlv entity
entry_relay = Bech32::Nostr::TLVEntry.new(Bech32::Nostr::TLVEntity::TYPE_RELAY, 'wss://relay.nostr.example')
entry_author = Bech32::Nostr::TLVEntry.new(Bech32::Nostr::TLVEntity::TYPE_AUTHOR, '97c70a44366a6535c145b333f973ea86dfdc2d7a99da618c40c64705ad98e322')
entity = Bech32::Nostr::TLVEntity.new(Bech32::Nostr::NIP19::HRP_EVENT, [entry_relay, entry_author])
entity.encode
=> 'nevent1qyvhwumn8ghj7un9d3shjtnwdaehgu3wv4uxzmtsd3jsygyhcu9ygdn2v56uz3dnx0uh865xmlwz675emfsccsxxguz6mx8rygstv78u'

v1.3.0 release

This release contains following refactoring:

• Simplify unpack process(2304148)
• Move convert_bits method in SegwitAddr class to Bech32 module as module function to allow use from any codes(95c4ebc).

v1.2.0 release

This release adds the ability to encode and decode Bech32/Bech32m in the CLI.

See https://github.com/azuchi/bech32rb#cli

v1.1.0 release

This release adds support for Bech32m.
