*split()*.





I think you might find that the last character of indesejaveis.txt is a 
\n (as is the case for many, many files) so in actual fact your original 
split did exactly what it was supposed to do.


And your work around is correct. Although it is not actually a work 
around it is a very common construct when dealing with text files.


So, I very much doubt there is a bug in File.Load()

Re: [Gambas-user] Mystery with file.load and regexp

[Tony Morehen]

File.Load is working fine.  It is just loading a file that has a 
trailing "\n".  Split then adds an empty string as the last entry in the 
array.  This is Split's documented behaviour.  Adding the True option 
suppresses empty entries.  Note that Split will also add an empty entry 
for any blank lines ie "\n\n".  The True option will also suppress those 
empty entries.


A word of caution:  the True option will not suppress lines that are 
comprised entirely of spaces.  I'd test to see if those kind of lines 
also cause problems.

Concerning RegExp I have another mysterious thing to understand

If I do something like:

re.utf8)Next*
The expression gest compiled. No error.
Neverthelesse, if I the same words from a file, using this expression:

*Dim Searchfor As New String[] = Split(File.Load("Strings"), "\n")*

re.Compile will not work. It will display an error message saying there is
nothing to compile. Now, if I do:


*print "@" & Searchfor[n] &"@\n"*
in both cases I will see precisely the same output. I can't distinguish
one from the other. So, why it compiles in the first case, but does not in
the second?

This is the mystery I must solve with a little help from a good soul out

[Gambas-user] Isn't bracket regular expression compatible with UTF8?

[Fernando Cabral]

I have been trying something like *poder[^[:alpha:]*  so I  could find the
word "poder " ("poder" followed by an space) but not "poderão" ("ã" being
an alpha character in Portuguese.)

In English it could be like finding "power" but not "powerless".

Problem is that it seems [^[alpha]] includes accented characters like "á",
"é", "ã".

That is, accented characters are not understood as alpha, but not alpha.

Please, note that I have compiled it with the UTF8 flag:
*   re.Compile(poder[^[:alpha]], RegExp.utf8)*

Any hints?

[Gambas-user] gambas for MAC OS ppc/intel ?

[PICCORO McKAY Lenz]

i can see that there a FreeBSD install/compile how to in wiki:
http://gambaswiki.org/wiki/install/freebsd

since MacOS / ppc flavor are based lossely on FreeBSD, there's a MacOS
version of Gambas ?

and also a MacOS /intel version of gambas at least?

Re: [Gambas-user] who to detect if are running inside IDE

[PICCORO McKAY Lenz]

so in short investigations i have

  Public Sub Main()
print "running"
  #If Exec
print "in ide"
  #Endif
  End

so testing by normal steps to compile produce a exec (either a cgi or not)
so works for cgi:

  $ gbc3 -ga
  $ gba3
  $ ./test.gambas
running

but for other cases i see tha if gambas archiver for executables are not
run for distribute, it fails:

  $ gbx3 /tmp/testexec
running

in the reference mail it fails, but for production detection are good..
 due its only for set paths, vars and environment

this due, another way its detecting the gambas runtime environment.. seem
gambas create a lof of files in /proc, based on Application.Id.. and also
in "/tmp" ...

i'm very curious about how gambas made this in cygwin installations, and or
in macos/freebsd flavors (if any)

Well, I found a very easy way to do it:

It seems it can't be easier, can it?

[Gambas-user] Is it possible to read a file directly into an array?

[Fernando Cabral]

Is there a straightforward way to read a file directly into an array?
Say I have a file with several lines (lines ended with "\n").
I want to read each line and push its content as an item of an array.

Lets say the file contents are "a\nb\nc\n" and what I need is:

word[0] = "a"
word[1] = "b"
word[2] = "c"

Yes, I know I can LINE INPUT each line and copy it into the array.
But I have seen that Gambas has so many shortcuts that perhaps there is one
for this operation too.

Any hints?

I don't quite get your description of the problem. It seems self
contradictory. I mean this part:

Perhaps It should sound contradictory. That's because if I write directly

to a TextArea.text from
inside the program, it will show "À" correctly. Nevertheless, if I read the
same string from a file read into a variable and then try to display it...
it does not work.


Are you using ascii functions for UTF-8 at some point?


I only use ascii functions where there are no UTF-8 functions. For
instance, split().


I think we need to see your code to understand the issue.


I have attached a text file (ODT) as well as the code itself. Note that, in
order to run the code you will have to have unoconv installed.

If you comment the two lines bellow, the code will not work.



* RawText = RegExp.Replace(RawText, "À", "à") RawText =
RegExp.Replace(RawText, "Ó", "ó")*

This happens because for some mysterious reason, the QT library seems to
get confused
with *À* and *Ó*. But not always!

Jussi



Not mysterious: you are using UTF-8 separators with Split(), whereas 
Split() only deals with ASCII strings. Consequently, the resulting 
MatchedWords array gets incorrect UTF-8 strings.


If you have took the time to just trace your program between line #54 
and line #60 and watch the MatchedWords array, you would have seen the 
problem.

without them.

[Gambas-user] IconView strange behavior.

[Gianluigi]

Or I did not understand how it works or ...

If I set Editable property on true, I expect to be able to change the icon
text and receive the Rename event to complete with Move.

This does not happen in Trunk 8113, should I report it as an error?

Gianluigi
