|
|||
* +filetype+ _str_: arbitrary string defining the type of the file
|
||||
filetype dependant actions should hook on this option changing for
|
||||
activation/deactivation.
|
||||
* +completions+ _str-list_: option used for external completion, the
|
||||
first string should follow the format
|
||||
_<line>.<column>[+<length>]@<timestamp>_ to define where the completion
|
||||
apply in the buffer, and the other strings are the candidates.
|
||||
* +path+ _str-list_: directories to search for gf command.
|
||||
* +completers+ _str-list_: completion systems to use for insert mode
|
||||
completion. Support +option+ which use the +completions+ option, and
|
||||
+word=all+ or +word=buffer+ which complete using words in all buffers
|
||||
(+word=all+) or only the current one (+word=buffer+)
|
||||
completion. given completers are tried in order until one generate some
|
||||
completion candidates. Existing completers are:
|
||||
- +word=all+ or +word=buffer+ which complete using words in all buffers
|
||||
(+word=all+) or only the current one (+word=buffer+)
|
||||
- +filename+ which tries to detect when a filename is being entered and
|
||||
provides completion based on local filesystem.
|
||||
- +option=<opt-name>+ where <opt-name> is a _str-list_ option. The first
|
||||
element of the list should follow the format:
|
||||
_<line>.<column>[+<length>]@<timestamp>_ to define where the completion
|
||||
apply in the buffer, and the other strings are the candidates.
|
||||
* +autoreload+ _yesnoask_: auto reload the buffers when an external
|
||||
modification is detected.
