Best way to slurp a file into a string?

Wes Gamble

3/22/2006 8:59:00 PM

All,

I would like to capture the entire contents of a file in to a string (a
la Perl) - is this the best way to do it?

File.open(@document.path, r) do |f|
@lines = f.readlines
html = @lines.join
end

so that the html variable has all of the contents of f.

Is there a better/easier way?

Thanks,
Wes

IO.read(@document.path)

Isn't it better to do the block thing so that the file gets closed,
etc.?

I see that IO.read takes care of that.

Sorry for the dumb question.

I knew that this would be as easy (or easier) than in Perl!!!

Nope. No need to worry about that with IO.read. It's not returning an open
handle, just a string.

Personally File.read makes more sense to me than IO.read... But i've
used both.

Hello,

how can you make a FXLists' frame sunken?
It inherits from FXWindow which has a flag named FRAME_SUNKEN.
But in FXList it has no effect.
I even made a sunken container and put the list in, but that looks horrible!

I appreciate your help.

PS: this I tried:

@leftlist = FXList.new(@secondhframe, nil, 0, LIST_NORMAL |
FRAME_SUNKEN | LAYOUT_FILL_X | LAYOUT_FILL_Y)

@leftlist = FXList.new(@secondhframe, nil, 0, FRAME_SUNKEN |
LAYOUT_FILL_X | LAYOUT_FILL_Y)

@leftlist = FXList.new(@secondhframe, nil, 0, FRAME_SUNKEN)

Like Yura said, you need to put FXList inside some other container
that is derived from FXFrame. And also, per Yura's code, be sure to
specify zero padding around all four sides of the frame. If you use
the default padding (which IIRC is two pixels on each side) it
probably won't look too nice.
