| 6 | Ruby version of TwitterIrcGateway |
|---|
| 7 | ( http://www.misuzilla.org/dist/net/twitterircgateway/ ) |
|---|
| 8 | |
|---|
| 9 | ## Launch |
|---|
| 10 | |
|---|
| 11 | $ ruby tig.rb # daemonized |
|---|
| 12 | |
|---|
| 13 | If you want to help: |
|---|
| 14 | |
|---|
| 15 | $ ruby tig.rb --help |
|---|
| 16 | |
|---|
| 17 | ## Configuration |
|---|
| 18 | |
|---|
| 19 | Options specified by after irc realname. |
|---|
| 20 | |
|---|
| 21 | Configuration example for Tiarra ( http://coderepos.org/share/wiki/Tiarra ). |
|---|
| 22 | |
|---|
| 23 | twitter { |
|---|
| 24 | host: localhost |
|---|
| 25 | port: 16668 |
|---|
| 26 | name: username@example.com athack |
|---|
| 27 | password: password on Twitter |
|---|
| 28 | in-encoding: utf8 |
|---|
| 29 | out-encoding: utf8 |
|---|
| 30 | } |
|---|
| 31 | |
|---|
| 32 | ### athack |
|---|
| 33 | |
|---|
| 34 | If `athack` client options specified, |
|---|
| 35 | all nick in join message is leading with @. |
|---|
| 36 | |
|---|
| 37 | So if you complemente nicks (ex. irssi), |
|---|
| 38 | it's good for Twitter like reply command (@nick). |
|---|
| 39 | |
|---|
| 40 | In this case, you will see torrent of join messages after connected, |
|---|
| 41 | because NAMES list can't send @ leading nick (it interpreted op.) |
