I believe I discovered that this custom sort function has to be
modified in one tiny way to work properly. Instead of
sort lines of fld 1 by valueList(word 1 of each)
you have to do
sort lines of fld 1 numeric by valueList(word 1 of each)
The valueList function returns a number, so the sort has to be
numeric. IIRC, this caused a problem for me until I figured it out. I
could be misremembering....

My understanding of the sort command is that I can tell it to sort
by a
particular chunk, and in which direction (ascending or
descending), and
by what form of data (numeric or date or text).
Indeed, the only examples in the docs are:
sort field "Output"
sort items of myInfo by word 2 of each -- sort by word 2 of the
line
sort lines of field thisField descending numeric by item x of each
I've never before seen a sort where the sort specifier is a literal
value. :\
If I simplify the above to move the function result inline, it would
look like:
sort lines of fld 1 by "Monday"
What exactly does that do, and how does it do it?
And where did you learn how do that? I can't find anything in the
docs
like that.
It's just a custom sort function. Rev evaluates the function before
sorting each line, so what it is actually sorting by is a number in
this
case. "Each" evaluates to the first word of each line in this case,
which the function then re-evaluates as the position in the list of
days
of the week. So when "each" is "monday" the sort number is 1. When
it's
Tuesday, the sort number is 2, and so forth.
