-- pastebuf
--
-- A script for viewing the content of a pastebin inside Weechat buffer.
--
-- Usage:
-- /pastebuf <pastebin-url> [<optional-syntax-language>]
--
-- To use syntax highlighting, set plugins.var.lua.pastebuf.syntax_highlighter to
-- an external command that will highlight the text. If the command contains
-- $lang, it will be replaced by the name of syntax language specified with
-- /pastebuf command. For example, to use pygmentize as syntax highlighter:
--
-- /set plugins.var.lua.pastebuf.syntax_highlighter "pygmentize -l $lang"
