Opens zettel by linked value, most often a direct path link, but will
also look through the root dir to find a(n exactly) matching basename to
open.
If nothing is found in the root dir will open a new file to write with
the corresponding name. Careful, if the reference is a full path
definition, and the file does not exist, it will still open the
corresponding file at the correct location but when attempting to save
will generally complain if parts of the path are missing. They have to
be created manually or in some other place, this is outside the scope of
this plugin.
Renamed to 'files.lua' since it is the only module actively working on
the underlying filesystem so far -- gathering existing files and zettel
in the directories.
Open actions now make use of a 'link' data structure containing a text
and ref string, and the respective start and end positions on the line.
Additionally, parsers are now simple objects containing extraction regex
for extracting their text and ref link individually.
By choosing 'line' in the `zettel_link_following` option, the link to be
opened will be searched for on the complete rest of the line, meaning
from the cursor to the newline symbol onwards.
Action module contains the interactions the user can take directly with
the zettelkasten, and which in turn act on the editor.
First action to be taken is the opening of zettel links.
`action.open(mytext)` allows the user to pass in a md/wikilink-formatted
string from which the function will open the first found in the current
buffer.
`action.open_selected()` does the same, but looks at the cursor context
to get its string (the link under current cursor position as of now; in
the future probably also the next link on current line, and the first
link in visual selection)
