 buffer _G.buffer (module)\nA Textadept buffer object.\nConstants are documented in the fields they apply to.\nWhile you can work with individual buffer instances, it is really only useful to work with\nthe global one.\nMany of these functions and fields are derived from buffer-specific functionality of the\nScintilla editing component, and additional information can be found on the [Scintilla\nwebsite](https://scintilla.org/ScintillaDoc.html). Note that with regard to Scintilla-specific\nfunctionality, this API is a _suggestion_, not a hard requirement. All of that functionality\nalso exists in `view`, even if undocumented.\nAny buffer fields set on startup (e.g. in *~/.textadept/init.lua*) will be the default,\ninitial values for all buffers.
