Hello,
is somebody interested on something like this? There is a little problem with
the FXChoiceBox.ask which I just replaced by a
p "Warning"
and I have some difficulties how to quote a "\" and "(" in a
regular
expression but everything else seems to work in here. Can somebody help me
out here?
Is there a database of code snippets, where I would put something like this,
or do you guys think, people should write this kind of stuff (extensions of
widgets) themselves?
See you,
Uwe
by the way, "*" is a wildcard in here...

it''s quite nice. i definitely will have use for that. there are also some little things, that are not so cool about it: * configuration via constructor (yes, fox is all like this, but it makes classes definitly less easy to use ... especially if there are many of them) * inconsequent coding style: appendItem vs append_array. but that is easy to fix ;) i appreciate that you share your code with us. should be done more often on this list. thanks a lot!! -- henon On 2/28/06, Uwe Hartl <uwe.hartl at gmx.net> wrote:> > Hello, > > is somebody interested on something like this?

Ok, I will fix these. I started programming a couple of weeks ago in ruby
after a 9 year brake, coming fron C. Sorry, I will improve.
A couple of things I would need help with:
I tried "fillItems" from the FXList and get a segfault. Thats why I
wrote
append_array(txt). Can somebody verify this, please? In my case we look at an
Gentoo system, I have no idea if this is system specific.
I want to have a String: "blabla\(blabla" to make the "(" a
normal character
for the regex;
Here are my Attempts
irb(main):089:0* "blabla\(blabla"
=> "blabla(blabla"
irb(main):090:0> "blabla\\(blabla"
=> "blabla\\(blabla"
irb(main):091:0> ''blabla\\(blabla''
=> "blabla\\(blabla"
Can somebody tell me how I can do this? I either get two backslashes or I get
none. What do I miss?
Thanks
Uwe

Uwe Hartl wrote:> I want to have a String: "blabla\(blabla" to make the "(" a normal character > for the regex; >What string are you trying to match? and I also suggest you post the actual code. The complication here is that if you are assigning to a string and then using the string in an RE then there *two* levels of quoting necessary, one for the string and one for the RE with the \ needing to be quoted twice and the ( once. i.e. to get a single \ in the RE you would need \\\\ in the string -- this gets unmanageable really fast so I recommend not using variables in REs unless you really have to. We need to see exactly what you are trying to do to solve this one there are too many ambiguities. Russell

I either get two backslashes > or I get none. What do I miss?You''re missing that irb displays stuff (almost) the way Ruby is interpreting it. "\(" would always become "(" because Ruby tries to interpret the backslash as a special char (\n, \r, \t etc.) but fails to find a ''r'', ''n'' or ''t'', so the slash is just ignored. To check this, try typing "blabla\t(blabla", which will give you "blabla\t(blabla". Irb returns "\\(" as "\\(", but this doesn''t mean that there will be two backslashes in the actual string output. If it would print "\" you might expect a special char here (=> misleading). To check your expressions, assign the string to a variable and print its value: jannis at nebelsee ~> irb irb(main):001:0> var = "bla\test" => "bla\test" irb(main):002:0> puts var bla est => nil irb(main):003:0> var = "bla\\test" => "bla\\test" irb(main):004:0> puts var bla\test => nil irb(main):005:0> var = "bla\(test" => "bla(test" irb(main):006:0> puts var bla(test => nil irb(main):007:0> var = "bla\\(test" => "bla\\(test" irb(main):008:0> puts var bla\(test => nil Hope this helps, Jannis -------------- next part -------------- A non-text attachment was scrubbed...
