Added modules@hyperlink. A new presser tool which will convert text to a
hyperlink in markdown format.
- Firstly the function identifies the mode. If visual-mode, the text
selected is used. If normal-mode, the text used is whatever is
identified under the cursor.
- Secondly, if the text is identified to be a valid URI schema, then
hyperlink will automatically make the conversion.
- If the text isn't a URI schema, then a new steamer is created to
allow for the user to enter a URI.
Added actions@hyperlink_exec. Responsible for acting upon an execution
call from keybinding. Function gets the contents of the buffer and makes
call to actions@suburl.
Added actions@suburl. This function specifically performs a substitution
of text in a buffer line and replaces it with a hyperlink, formatted as
markdown.
M@clean_buffer no longer escapes sequences (caused undesirable
behaviour).
Added M@get_selection which will return four values indicating the
starting row/column and ending row/column of a visual-mode selection. If
no selection has been performed in buffer instance, values may be -1.
Value is "cached" as defined Vim behaviour of '< and '> positions.
Added M@subslice is used to get a substring of a word between two
whitespace characters (i.e., spaces). The `line` is the string to check,
and `col` is a position (e.g., from the cursor) within the word which
will be extracted. Return value is a table of starting and ending
indices of the original string.
