" Input-related, select from a list etc.
" If a list is bigger than this value, don't try to be smart when
" selecting an item. Be slightly faster instead.
" See |tlib#input#List()|.
TLet g:tlib#input#sortprefs_threshold = 200
" If a list contains more items, |tlib#input#List()| does not perform an
" incremental "live search" but uses |input()| to query the user for a
" filter. This is useful on slower machines or with very long lists.
TLet g:tlib#input#livesearch_threshold = 1000
" Determine how |tlib#input#List()| and related functions work.
" Can be "glob", "cnf", "cnfd", "seq", or "fuzzy". See:
" glob ... Like cnf but "*" and "?" (see |g:tlib#Filter_glob#seq|,
" |g:tlib#Filter_glob#char|) are interpreted as glob-like
" |wildcards| (this is the default method)
" - Examples:
" - "f*o" matches "fo", "fxo", and "fxxxoo", but doesn't match
" "far".
" - Otherwise it is a derivate of the cnf method (see below).
" - See also |tlib#Filter_glob#New()|.
" cnfd ... Like cnf but "." is interpreted as a wildcard, i.e. it is
" expanded to "\.\{-}"
" - A period character (".") acts as a wildcard as if ".\{-}" (see
" |/\{-|) were entered.
" - Examples:
" - "f.o" matches "fo", "fxo", and "fxxxoo", but doesn't match
" "far".
" - Otherwise it is a derivate of the cnf method (see below).
" - See also |tlib#Filter_cnfd#New()|.
" cnf .... Match substrings
" - A blank creates an AND conjunction, i.e. the next pattern has to
" match too.
" - A pipe character ("|") creates an OR conjunction, either this or
" the next next pattern has to match.
" - Patterns are very 'nomagic' |regexp| with a |\V| prefix.
" - A pattern starting with "-" makes the filter exclude items
" matching that pattern.
" - Examples:
" - "foo bar" matches items that contain the strings "foo" AND
" "bar".
" - "foo|bar boo|far" matches items that contain either ("foo" OR
" "bar") AND ("boo" OR "far").
" - See also |tlib#Filter_cnf#New()|.
" seq .... Match sequences of characters
" - |tlib#Filter_seq#New()|
" fuzzy .. Match fuzzy character sequences
" - |tlib#Filter_fuzzy#New()|

" By default, typing numbers will select an item by its index. See
" |g:tlib#input#numeric_chars| to find out how to change this.
"
" The item is automatically selected if the numbers typed equals the
" number of digits of the list length. I.e. if a list contains 20 items,
" typing 1 will first highlight item 1 but it won't select/use it
" because 1 is an ambiguous input in this context. If you press enter,
" the first item will be selected. If you press another digit (e.g. 0),
" item 10 will be selected. Another way to select item 1 would be to
" type 01. If the list contains only 9 items, typing 1 would select the
" first item right away.
"
" type can be:
" s ... Return one selected element
" si ... Return the index of the selected element
" m ... Return a list of selected elements
" mi ... Return a list of indexes
