The "fmttext" library is used for
formatting text in various places in
KittenOS NEO.
It's recommended that you only load
this library when you need it, and
release the value immediately after,
as it is rarely called, and has no
sticky objects that could cause
duplicated library issues.
If using neoux, the pad and fmtText
functions are proxied there in a
load-on-demand form, such that you
can call them, and the library is
loaded for that call.
Essentially, it's job is to take some
safeTextFormat'd text, and turn it
into a column of a given width.
It has two functions for this task:
pad(text, len[, centre[, cut]]):
Pads the given safeTextFormat'd
string to a given width, returning
the resulting string.
If centre is true, then the text is
centred within the area given -
otherwise, it is left-justified.
(Values that are not nil or true
are reserved for future use.)
If cut is true, then the text may
be reduced in size if necessary.
Otherwise, text that is too long is
not reduced.
fmtText(text, width):
2018-04-24 07:39:01 +10:00
Formats the given safeTextFormat'd
string to a list of lines with a
given max. width and word wrap, if
possible (words will be broken by
letter if necessary)
If there are newlines in the text,
these newlines are respected.
If the width is less than 2, then
this function may fail in various
ways, up to and including freezes.
