That's a problem. Will Qt5 have a HTML display widget of any sort?

Qt5 is pretty stable. The only real problem AFAICT is TextEdit isn't
available in Qt5 in 3.8.4
This means you can't have TextEdit and WebKit in the same program at
the same time.
This issue is fixed in svn I believe.

From the 3.8.4 sources: main/lib/gui.qt/main.c
I interperse my "translation", tell me where I'm wrong

59 if (use == USE_NOTHING)
so GB_GUI hasn't been set
 60 {
 61 use = USE_GB_QT4;
 try Qt4
 63 env = getenv("KDE_FULL_SESSION");
 64
 65 if (env && !strcmp(env, "true"))
 66 {
 67 env = getenv("KDE_SESSION_VERSION");
 68 if (env)
 69 {
 70 if (strcmp(env, "4") == 0)
 71 use = USE_GB_QT4;
 72 else if (strcmp(env, "5") == 0)
 73 use = USE_GB_QT5;
 74 }
 75 }
 76 }
 look for some KDE variables (which won't be set at all on non-KDE systems)
 78 switch (use)
 79 {
 80 case USE_GB_QT4: comp = "gb.qt4"; break;
 81 case USE_GB_QT5: comp = "gb.qt5"; break;
 82 default: comp = "gb.qt5"; break;
 83 }
turn setting constant into a string (remember we have set to
"USE_GB_QT4" above so "gb.qt4" will always be selected here)

 85 if (GB.Component.Load(comp))
try the first one
 86 {
 87 comp2 = use == USE_GB_QT5 ? "gb.qt4" : "gb.qt5";
 that didn't work, try the other
 89 if (GB.Component.Load(comp2))
 90 {
fail if that doesn't work either.
 91 fprintf(stderr, "gb.gui.qt: error:
unable to find any QT component\n");
 92 exit(1);
 93 }

my patch is very, very simple: line 61 becomes "use = USE_GB_QT5;",
and so Qt5 is loaded first.

I confess I've given up trying to find a 'correct' solution that
covers all cases.

The problem quite complicated. Gambas looks for Qt4 and Qt5. If both are found,
Qt4 is loaded.
However, Debian does not have WebKit for Qt4 (it was taken out because
they couldn't keep it secure, and wanted to concentrate on Qt5-WebKit,
I believe)
Consequently, the IDE and many other problems will crash (because they
load Qt4 but then can't find WebKit).

So, I tried making it a Conflicts: if you try to install the IDE, it
tries to remove Qt4. which causes more problems as noted above.

The other option is to patch Gambas on Debian so it preferentially
loads Qt5 (a bit of work). That will get the IDE working, but many
other programs won't run
(because Qt5 doesn't quite have the stability of Qt4, at least last
time I checked)

Sadly, my recommendation to all (our) users has been stick to
Mint/Ubuntu and the PPAs for now.

[Gambas-user] TextEdit on Qt5

[Ian Haywood]

This was a lot simpler than I thought.
I enclose a working patch. Two outstanding issues:
- the TextEdit has a grey background (the system default) and ignores
setting .Background = Color.White
- the documentation doesn't appear in the IDE (because it's looking
for qt4.TextEdit, whereas the docs wil lbe under
qt5.ext.TextEdit)

I suspect I'm missing something (i.e. if it's so easy presumably
Benoit had a good reason for not doing it at the start)
Anyway I hope this will kick the work along... as I said several of us
*really need* TextEdit!

Is he/she using TextEdit?

This is the problem I have run into: Debian no longer supports Qt4,
and Qt5 on Gambas
has no TextEdit, so my project doesn't load.

I would like to enter in another plea for TextEdit to be supported on Qt5.
Previous discussions have been around a Gambas-native rich text
editor: agree that's a
lot of work, but also unnecessary: Qt5 has a rich text editor (see
http://doc.qt.io/qt-5/richtext.html)
I don't see why that cannot be used.

I'd have a crack at doing it myself but I have limited time and
haven't used C++/Qt for many years
so it would take some time to relearn.
Would be happy to pay if there are others able to here.

One of the issues is, if not you, then gambas doesn't really have a
Debian "maintainer". I'm happy to help, but I'm wary of doing a lot of
work without a debian developer active and interested. in the past I
have had contributions sitting in alioth git waiting for weeks/months
to be uploaded.
(unfortunately debian does not have an equivalent to "launchpad" for
making third-party .debs available)

when packaging for a distro the interpreter should work "out of the
box", users should be
able to type "gambas3" or launch form the menus, not "GB_GUI=QT5 gambas3"

One solution is to have a wrapper shell script that sets the variable
Easier IMHO is to patch main/lib/gui.qt/main.c to prefer qt5 over qt4
which is probably what Debian will end up doing.

[Gambas-user] running IDE with Qt5

[Ian Haywood]

is there a way to run the IDE with Qt5 only (not Qt4 at all)
The reason is Qt4 webkit is getting pulled out of Debian, so we are
not allowed to depend on it anymore.

I thought so, but I am finding that on 3.8.3 at least, if gb.qt4 and
gb.qt5 are both present,
gb.qt4 is used (which then fails, as no gb.q4.webkit is present)
Removing gb.qt4 from the system is the solution: the IDE then has nbo
choice but to run successfully with gb.qt5

 The rule is the following: A program made with Gambas 3.X will work with

 behaviour of a bug that is fixed in a new version.
the issue is developers usually have a bleeding-edge version, so
when they compile gambas binaries, they won't work on older versions
of the runtime that some distros (*cough* debian *cough*) use.

what I have done is produce a source debian package that then gets
compiled using gbc3 on the command line (just like building a C program)
with whatever version is on that debian version.
 You have to do with that rule, as I don't see any other rule that allows
 me to continue working on it.
ideally back-compiling to older versions as an option in the IDE,
but I appreciate that would be quite hard to do, your
time may be  more usefully spent on other things.

currently libraries must sit in a directory on $PATH. On most systems

Therefore a user cannot install libraries that compiled programs can use AFAICT

I've proposed this before I know: a separate environment variable for
directories to search, presumably GAMBASPATH (like PYTHONPATH, or
Java's CLASSPATH)

This would also help with my .project/.startup svn issue (which can't
be fixed by Gambas directly as there is a lot of non-Gambas stuff in

[Gambas-user] libraries with svn

[Ian Haywood]

Richard Terry and I have run into a problem
Our project uses one library (and may use more as we hive up the
project into logical components)
But, it will be in different locations on our systems (mine in
/home/ian/easygp/base.gambas, his funnily enough is
/home/richard/easygp/base.gambas, or similar), and obviously our third
developer (who  isn't called richard or ian) will have the same
problem.

each time one of us updates svn, the .project file is changed to ur
setting, thus breaking the package for the other one.

Is there a way to exclude changes to the project file from svn
updates? (I know this can be done through configuring svn manually,
which I will do, but is their an official gambas solution?)

 I haven't packaged before but know my way around bash scripts, svn, git

start with the debian packaging guidelines to get an idea of how the
system works in general. https://wiki.debian.org/IntroDebianPackaging
Next, download the debian 3.5.4 packages in sid.
https://packages.debian.org/source/sid/gambas3 [look at the bottom of the page]

These debian packages will compile as-is on later versions of ubuntu,
all you will need to do is change the name of the target distro in
debian/changelog from unstable to raring, quantic or whatever.
Your problem is going to be the older versions, some gambas3
subpackages [gb.jit, gb.media, possibly a couple of others] just won't
compile as the relevant libraries are too old. You will need to
produce versions of gambas3 that don't have those subpackages.

[as an aside, this is why I've never bothered producing a version for
debian stable, lots of stuff won't compile and so the reality is most
debian people who want to run an up-to-date gambas will need to
upgrade their whole system anyway]

[Gambas-user] loading PDF widget very slow

[Ian Haywood]

I've noticed that suddenyl loading any PDF became very slow (1-15
seconds to load)
the PDFs are small and no my local drive, so should load almost immediately.

then I discovered chanigng my default printer fixed it

using strace, this is what's happening while I wait for the PDF to load

connect(34, {sa_family=AF_INET, sin_port=htons(631),
sin_addr=inet_addr(192.168.1.8)}, 16) = -1 EINPROGRESS (Operation
now in progress)
fcntl64(34, F_SETFL, O_RDWR)= 0
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=34, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)

my interpretation is that it's trying to talk to the printer on
192.168.1.8: that's my printer at home, not available when I'm at work

but the real question is: why does the PDF widget even care? I don't
want to print, just look at the PDF

[Gambas-user] Fwd: libraries and locations: feature request

[Ian Haywood]

I've started using gambas libraries to break my projecty up into more
manageable components.

My understanding is libraries must be in the same directory as the
compiled executable when deployed: so that's /usr/bin

The debian packaging system complains that I don't have a manpage for
each of my libraries: but only some of them will be run directly, some
are only for use as gambas libraries.

I can see a collision with debian policy: libraries should go in
/usr/lib, ideally /usr/lib/gambas3/ or something like that.

Can we have gambas look in /usr/lib/gambas3 as well as /usr/bin for libraries?

Re: [Gambas-user] Accessing the nth item in a collection

[Ian Haywood]

On Wed, Jun 4, 2014 at 9:59 PM, Tobias Boege tabo...@gmail.com wrote:

 Oh, I just saw the added to bit. That's not possible with AvlTree and also
 won't be with Collection.

 Then I suppose that you create a custom Collection class and make it record
 the first and last items added. For the general case of the n-th added item,
 you really need to sort your keys by the point in time they're inserted and
 that's plainly an array using the Add() method.
My first question is why not just use an Array full-stop: by
definition that is the structure for accessing
items by order.

 Generally, if you want to have the same data *sorted* in different ways (and
 you want sorted because otherwise you would need to loop through the data
 which you don't want), it sounds plausible that you need the data twice, but
 in diffent containers and sorted differently.
Correct.
if the things in question are Objects of any type, then internally
what's being held in the Array or Collection are pointers
to the objects, so extra memory use is minimal. In this case IMHO the
most graceful  and efficient solution is to have both an Array and a
Collection of the same objects.

If that doesn't work then I'd have a String[] holding the keys to the
collection, this means two lookups so a bit of a speed penalty (but
Gambas is fast at this stuff, I doubt you'd notice)

on an ARM SoC. I can't help you on OpenGL (and there doesn't seem much
point on ARM) but I have got webkit and the rest
of gambas running fine.

From your logfile the punchline is

configure: WARNING: Unable to met pkg-config requirement: QtWebKit = 4.5.0
configure: WARNING: gb.qt4.webkit is disabled

which means you don't have the right development package installed,
it's called libwebkit-dev on
debian-based distros, dunno about the others.

If you are on a debian-based system, try upgrading to the latest
testing and then install gambas directly
('apt-get install gambas3), this *should* work as there will be
pre-compiled ARM binaries for gambas in the Debian repos.

As a very general comment: gambas is a big complex program, compiling

you are probably going to have a much better experience with

 There seems to be two problems here.
 1) Why is the Error instance a null, and
are you sure the whole Error is Null
is it just Error.Backtrace?
which isn't set by the TRY form (it is when you handle errors using CATCH)
 2) (Harder) If, when trying to invoke an unknown method in a classifier then 
 should not the interpreter raise the normal error  Unknown Symbol  blah blah
when I'm not sure if a method exists on a Form I use Object.Call which
seems to behave a bit better in this circumstance.

no, what's in the standard ubuntu repos is very old (3.1.1), you need
to use kendek's PPA as described.
your error is probably that the bytecode is too new for the 3.1.1

 Also added Raspbian to the index of distributions.
the current jessie packages are a bit buggy, the IDE can crash.
3.5.2-2 is slowly percolating through the debian system and should be
reasonably stable.

have a look at https://wiki.debian.org/AptPreferences, it explains how

 Any idea why this is happening?Seems strange that explicitly setting a

 maybe it has to do with a structure being embedded in another structure?
i doubt structures are the issue. floating point values are stored in
binary internally so there is a translation between decimal for humans
and binary which imparts a slight rounding error
can you try Double: this won't fix the problem but will reduce it at a
cost of more RAM

if you need 100% decimal accuracy (it's usually only high-end
financial stuff where you do), then look at gb.gmp component. Again it
will cost you in RAM and speed.

[Gambas-user] Error.Backtrace

[Ian Haywood]

I have discovered that Error.Backtrace is not always correctly set.
if an error occurs in a TRY expression Error.Backtrace remains with the
previous error.
Error.Where and Error.Text are set correctly.

This caused us a lot of problems as we log Error.backtrace to find
errors on user systems.

I attach a mini-project that demonstrates this.

Surely it wouldn't slow performance to set Error.Backtrace to NULL?

 I admit it is actually a bit weird, but I don't understand why it is a

Hmm, because Catch only operates at the level of a whole function we do use
TRY and test for errors a fair bit.

I can't reproduce it myself: works fine on my box.
Is there any way to know what icon file gambas is looking for?

[WARNING: Debian packager discussion coming up, look away if you are

it is possible to use | in the Depends: field to make a package depend

 Gambas3-gb-desktop-gnome package is depend from gambas3-gb-desktop, but
 vice versa is not true (in other words, the previous contents are not
 part of the latter). If use gb.desktop component on GNOME desktop, the
 following error message comes up: Cannot load component
 'gb.desktop.gnome': cannot find component
is there a gambas3-gb-desktop-kde? I didn't think so, if but there is
you can use the same trick
If not I'd pick some kde package that represents the desktop as use this

[Gambas-user] Gambas self-extracting installer (4)

[Ian Haywood]

On Sunday, October 27, 2013, Benoit Minisini
gam...@users.sourceforge.net mailto:gam...@users.sourceforge.net wrote:
 But I don't think it's a good idea to ask for the root or sudo password
 to installed Gambas package, for security reasons (can you really trust
 that self-extracting installer?)

 Instead, I think I will just tell the user which packages he must
 install himself before being able to complete the installation.

An installer without root access doesn't seem that useful IMHO as it
would end up just displaying a long list of complex commands to enter
into a terminal.
Most people using it wouldn't understand the commands (otherwise they
wouldn't need the installer) so from a security point of view you gain
nothing by making them cut and paste into a terminal window - they still
have to trust that you haven't embedded a rm -f / in there.
 I suggest detecting gksu or kdesu on the system and using those, this
means your code doesn't have to handle the root password.

 Moreover, I will try to provide the installed program with all needed
 Gambas components inside. So, provided that the dependencies of these
 components are already installed, nothing will need to be installed.
If you can automatically install whatever library you might as well
install its gambas binding as a package too.

 For security reasons, maybe this packager should be able to install the
 program locally only.
I don't think installing locally is a good idea or particularly useful
IMHO. In practice you will almost always need root access to install
some dependency, so you might as well install the program itself the
normal way in /usr/bin while you're at it.

[Gambas-user] leaving .ShowDialog() via an exception can crash Qt

[Ian Haywood]

this is a contrived example in which Window.ShowDialog generates an
exception which is then caught by the calling code, this in turn makes
Qt crash with signal 11
I enclose the gdb stacktrace.

In my program I fixed it by catching and managing the error inside the
form on which ShowModal is called, so ShowDialog returns an integer to

Not sure whether this is worth fixing as it is admittedly a bizarre
way of dealing with errors: would be good if it can be a gambas error
instead of a signal 11
at least a warning in the docs that dialog boxes must manage their own
exceptions

This is useful, thanks

In your example code you stated there is no automatic way to convert
strings to hex. It is possible to do using a loop and the Hex$
function, like so:

Public Function String2Hex(s As String) As String

  Dim ret As String = 
  Dim i As Integer

  For i = 1 To Len(s)
ret = Hex$(Asc(s, i), 2)
  Next
  Return ret

[Gambas-user] Gambas 3.4.1 Debian packaging

[Ian Haywood]

Ok, I have finally got Gambas compiling and building all packages on
Debian wheezy

They are available on a private repository, add the following to your
/etc/apt/sources.list

deb ftp://ozdocit.org/pub/easygp/ easygp main
deb-src ftp://ozdocit.org/pub/easygp/ easygp main

easygp is the project I am working on with Richard Terry, it is a
massive project and a reasonably good stress-test, however it doesn't
use every Gambas package, please report any problems.

A couple of small questions to help with Debian packaging:

- gb.net.pop3: is this component written purely in Gambas or partially
in C? where is it's source code? all I can find is the bytecode-compiled
file /comp/src/gb.net.pop3/gb.net.pop3.gambas

- debian packager complains about executables gbs3 and gbw3 don't have
manpages (it's a Debian rule all executables have a manpage). I'm happy
to write them if someone can point me int the direction of some
documentation about what they do (presumably for scripts and webpages I
know, but how they work, command-line options, etc)

[Gambas-user] compiling on Debian

[Ian Haywood]

I am currently trying to compile gambas on debian

it now sees to work better: whether this is due to fixes in gambas or
debian libraries being slightly less ancient and catching up with
gambas requirements, I'm not sure.

BUT
the file /usr/lib/gambas3/gb.qt4.gambas does not exist and the
existing Debian packaging scripts expect it (i.e. it used to exist
back when Gambas was last successfully packaged: 3.1.1)
gb.qt4.so and gb.qt4.component are generated.

is this a probem? or has the way native gambas components work changed?

 that's may be why that file is not generated anymore.
Thankyou Adrien, that solves the puzzle.
It's relatively easy to amend the Debian packaging scripts so they

 This is becoming very painful.

 Is there any way to turn off the way constructors consume parameters?
It's a core language design decision, so I doubt it.
Personally instead of using the official constructor _new I often
have a separate
Init( ) function which is called immediately after instantiation

foo = New MyClass()
foo.Init(someParameter)

Messy, but because .Init( ) is an ordinary function in the eyes of
the the Gambas compiler, ancestor
classes to not consume parameters in the same way, plus it is only
overridden in the hierarchy when required.

Unfortunately Gambas doesn't allow any change in function signatures,
so if you wanted an extra parameter in a descendant
constructor you would have to have an Init2 method which then calls
Me.Init()

[Gambas-user] Regular expression searching

[Ian Haywood]

I have often missed in Gambas the ability to search through strings
using a regular expression and
provide a function to create replacements
Gambas doesn't have procedural pointers or closures, so it's
impossible to do it like in ruby/python/etc, but I've found the same
can be achieved using an iterator

IN the hope it is useful for others this is my module CRegex.

Here's an example, it turns the HTML tag quot; into alternating
opening (``) and closing ('') quotes as required by the LaTeX system

  r = New CRegex(quot;, s, Regexp.Caseless)
   flag = False
   For Each r
  If flag Then
 flag = False
 r.Set('') ' close quotes in LaTeX
  Else
 flag = True
 r.Set(``) ' open quotes
  Endif
   Next
   s = r.Subject

The key blocker for me is actually getting Gambas to compile on

If you can get it to compile, let me know how you did it and we can

[Gambas-user] patch for setting directory on EXEC

[Ian Haywood]

as part of my app, I run the LaTeX typesetting program via EXEC in Gambas

To cut a long story short, latex likes to be an a specific current
directory, which isn't possible in Gambas: EXEC always runs the in the
directory the interpreter was started in, Currently I use SHELL
instead and do something like cd the/directory/i/want ; latex
input.tex, but
this is inefficient (I have no other need of a subshell) and generally
feels kludgy.

This patch basically makes EXEC respect the PWD environment variable:
if PWD is set using the WITH keyword option to EXEC then
this is the current directory for the process spawned by EXEC.

try downloading the sources for the latest debian version, copy

I can integrate it with some stuff I've already done (I got LLVM 3.1 working
so gb.jit does compile), and send on to the debian developers for inclusion.

 Hi there!!

 Yesterday I released a new version of a personal project. Luckily, it

 that they either had problems with apt complaining about gambas versions,

 I provided a PPA for Ubuntu users which solves everything for them, but
 Debian users are left in the dark. They have 2 options only, compile
 gambas3 or use the Ubuntu PPA version corresponding to
 it's Debian installation (NOT recommended at all). And those who don't know
 how to do any, will complain about the official packages spitting out
 errors because they are either wrongly packaged or too out of date. This
 has been like this for months and contacting a maintainer is nearly
 impossible. Besides, the mailing list for Gambas packagers is full of spam,
 so it seems nobody is watching it.
If you can get gambas to compile on a debian system (I have really struggled)
please let me know as this is the block to getting an update out.

the other option (which is what I do) is to compile your project on the debian
version, this prevents the bytecode too recent problem and creates a version
debian users can use.

remember the debian philosophy is a bit different and software
packages don't get updated
as other distros.

Best option IMHO is to configure the  window manager to run a

 I don't understand why I had no problem with compiling Gambas on

android is not based on Debian. It has a heavily-patched linux kernel
and that's about where the connection with linux as we know it stops.
The runtime is totally different: no standard C library, no X, etc. I
think graphics is only available through their Java-based layer
so even if you could get Gambas C++ code to compile to ARM you can't
take Qt/GTK with you: so no graphics.

Plus no package management system as we know it: so users would have
to manually download and install gambas, then download and install
whatever application.

I suspect the only real solution is cross-compiling: i.e, turning
Gambas code into the dalvik bytecode instead of gambas bytecode,
plus reimplementing all the Gambas graphics and system APIs to the
Android APIs. Doable, but a crapload of work (basically a full rewrite
of gambas)

I suspect it would be faster to wait for Ubuntu-based tablets and
phones which apparently are coming out soon :-)

ON the emulated RasPi install kendek's

then grab all the dependencies
  apt-get build-dep gambas3

then grab the source code itself

 apt-get source gambas3

you may have to try different ubuntu versions of the packages to find
one compatible with your debian, I suggest you start with the oldest
(lucid)

you can then compile the debian packages for armel inside the source
directory like so

  debian/rules binary

this will give you a home directory full of .deb files, you can copy
across the ones you want to the NAS and install

   dpkg -i name of package

I have submitted gambas3 packages to the debian devs  and this is

The advantage is this will also get gambas3 into Linux Mint and a

[Gambas-user] adding functions to gb.db.postgresql

[Ian Haywood]

This is not so much a feature request as a question on how to get started.

There are two functions of the underlying postgres C interface that I
would like to expose to Gambas:
PQnotifies() [which returns postgres notification events], and
PQsocket () which returns
the FD of the socket the library is using to communicate with the
server, (my plan is to monitor it
using the 'Open .  fd For Read Watch' trick introduced in #4134)

I'm happy to do the C programming and submit a patch, what I'm unclear
on is how to extend
the Gambas bindings, it's clear from looking at the code that the
database components are all drivers for a fixed common API,
problem is this feature (notifications) is very specific to
postgresql, I don't know if it's possible to add
a couple of extra methods to gb.db.postgresql

thanks

try using gksudo, this assumes the user is set up to use sudo
[on Ubuntu this is usually the case, not on the others]
Generally it will ask for a password the first time root access is
needed but not thereafter.

The other solution is the traditional UNIX one: to have a small
program which is su exec, this is particular
mode which means the program is run as whoever owns the file, not the
user running it.

The mode is set using chmod

chmod u+s my-program

The wrinkle this that interpreted programs like Gambas can't do this,
only complied programs can
So you would need to write a small program in C/Pascal etc to do the
su work which the gambas program
calls.

[Gambas-user] IDE feature request: viewing collection-like objects

[Ian Haywood]

Benoit,

some time also we had a discussion about Collection semantics. In Gambas
setting the member of a Collection to NULL is the same as deleting it. I
am not trying to re-open this debate, I accept the decision and have
written a class with the semantics Richard and I want: it can have NULL
members, see cRow attached.
(It also has some database stuff which is very specific to our
application. please ignore that)
It uses _get and _put so it works like a Collection

Problem is, in the IDE it's an object and it is not possible to see the
members like a Collection.

So to my question: is it possible to extend the IDE so that when
displaying an object that overrides _get, _put and _next it displays it
like a Collection does?

There probably isn't a way do this directly, but I would have thought you could

I'd second this. Yes .src makes no difference for the GUI  IDE, but
src with no dot would also work just as well. The only point of the

 get_iplayer is a very complex PERL script which I do NOT want to amend.
 get_iplayer involves calling rtmpdump. rtmpdump can be executed in a

I wonder if the script is expecting user input such as a password, this
would cause it to freeze from within gambas as no input will ever come
Another possiblity is it produces heaps and heaps of output that
can't fit into the sOutput buffer, again programme becomes blocked
because it can't write.

Do you need sOutput? what happens if you run without this, just a plain EXEC?
In this case you might see errors or something come up in the gambas
terminal window which goves you a clue as to what's going on.

the other thing to do (which you may have already done of course) is
to run the exact command that gambas EXEC does in a gnome terminal, in
the same current directory as your gambas programme would be in, and
see what happens.

not really, as SQLite is not designed for use across the network.
MySQL/PostgreSQL clouds would work just fine.

If you wanted to go serious cloud you could run Gambas inside an
Amazon EC2 instance
and access via VNC or X. You could use SQLite in this situation.

 Hi,

 I'm a new Gambas user. Does anyone know if or when Gambas3 will show up
 in a Debian package, or if the Debian maintainer is likely to package
 one of the release candidates for the Debian Experimental repository

I have prepared debian packages and put them up for inclusion,

as you are only calling regexp once, you will only get one result, you
need to set up a While..Wend loop
to go through and find one, then use
Right$(-(Len(sRegExp.Text)+sRegexp.Offset)) to grab the reminder
of the string as search that, until the search fails.

This is inefficient (as a new string is created for each search).
Benoit, is it possible for Regexp.Exec to have an offset parameter,
this would allow more
efficient searching loops.
It would then be possible to write an iterator to grab all occurances
of a regexp, and make it 'easy' like in Ruby/Perl.

The immediate solution is to use dpkg --force-overwrite   overwriting

your icon will be the new gambas3 icon even for gambas2 files.

longer term I'm not sure. The gambas3 icon file can't go anywhere else

I'll research the options.

Re: [Gambas-user] arithmetic operations on dates and times

kevinfishbu...@eightvirtues.com wrote:
 How in the world would one do this? It's not really important that the
 client know the actual date, but it does need to know the time. The
 client should be able to add Timer to the game world time so it can
 keep an accurate 24-hour time while the player is playing. Basically the
 client would receive the game world time upon authentication, then look
 at gameworldtime + Timer to determine what time of day it was until
 the player stopped playing.

 I noticed that adding and subtracting to a date or time prints a
 floating point number, but multiplying or dividing complains about
 expected datatypes. Any insight or outright solutions would bring light
 and dark to the world. :)
Best suggestion is to formally convert the Date to a Float using
CFloat(...) function.
This number is the number of days since 8000BC, time is the fraction
part, so .5 for noon exactly, just before midnight will be .99 and so
on.

So your equation is

   ( CFloat(base_time) + CFloat(Now) ) * 4

You can then use CDate to turn this nuber back into a real date. BUT
my advice would be to send this number, before conversion, down the
wire to the client.

The client then calculates its own time using
  server_time + (Timer () / 86400.0)

86,400 is the number of seconds in a day, this is because Timer comes
in seconds and we want fraction-of-day to keep in line with everything
else.

This number can then be converted back to a date and displayed by the
client, using the clients own localisation setting (not the servers)
so users see the time in their own localisation, but servers and
clients don't stuff up if they are in different countries

 I inserted a 100 ms delay between packet transmission and this corrected

the first thing you should do is ask yourself again why you can't use TCP,
as it includes fairly fancy flow-control algorithms that have been honed
over the last 30 years by some very smart engineers.

If you want to stick with UDP, one option is instead of a simple 100msec wait,
use a timer (I assume these packets are sending updates about game state to the
client), for each update, if the last one has been sent less then,
say, 50msec ago, then don't send the
packet, but if more, then send (without a pause)
This means the system updates without any delay, but there is a
maximum rate of packets
being sent to avoid overloading the recipients buffer.
I wouldn't try to have the code figure out WAN versus LAN, there are
so many different network
configurations out there it is often not meaningful, plus it depends
on CPU speed as well as network
speed (you're problem is the network is too fast for the CPU)
. But maybe let users adjust this timeout value,
if they have fast computers and a fast network they may be able to lower it.

Re: [Gambas-user] Gambas 3 first release candidate

[Ian Haywood]

2011/5/21 Benoît Minisini gam...@users.sourceforge.net:
 Hi Gambas fellows,

 The Gambas 3 RC1 source package is available for download now on the website!

 - Who said already ?

 The aim of this first release candidate is ensuring that Gambas 3 will be
 compiled and packaged correctly on the most possible distributions.

 So, packagers, please raise from your graves and howl under the moon for each
 problem you encounter. And report them on the mailing-list of course.

 Some distributions will need a bit of lobbying to ensure that these packages
 are put on their main repositories.

 I will create a page on the wiki for each distribution to centralize all the
 information, like the one that already exist but are a bit of mess.
compiles fine on ubuntu lucid.
I have also changed the distro list to match Laurent's archlinux packages, see

PS the best way to get into Ubuntu and friends is to get the packages
in Debian, then it
will filter its way into all the Debian-derived distros. Debian has a
standard procedure for submitting new packages, let me know when
gambas3 is ready for this.
