I may just be responding to a typo but your struct is named MapObjec

Re: [Gambas-user] New Editor Side Bar

[Tony Morehen]

Fabian, it looks great and works like a charm.

By the way, I'm working on text editor which would benefit from a couple 
of minor changes to the text editor component.  Could you make 
$hDoc.Lines a read/write property of TextEditor and $hDoc.LineLength a 
read only property?

I working on a search function.  I can use Instr on TextEditor.Text to 
find the appropriate text but I can't select that text because the 
TextEditor.Select function requires Start Column, Start Row, End Column, 
End Row and there is no function to calculate those coordinates from the 
position in the text stream that InStr returns.

Exposing Lines lets me search for text on the same basis as the Select 
function, by row and column.  Exposing LineLength lets me easily write a 
function to go from Instr's text position to Select's column, row 
coordinates.

Indeed, I have already written a function to do that.  It splits 
TextEditor.Text into lines and then uses the String.Len function to 
calculate coordinates.  Unfortunately, it has to do that every time I do 
a search which is redundant given that TextEditor has the same 
information internally.

At some point, it may be useful to add a Select(selectionstart as 
integer, selectionlength as integer) method.  This would make TextEditor 
a virtual drop-in replacement for TextArea.

Re: [Gambas-user] A couple of ?s about encryption

[Tony Morehen]

Don't use .hidden.  There is nothing secure about and its only used by 
the development/installation environments.  Hidden directories in 
general do nothing for security.


Don't worry about open source/GNU.  All encryption programs use the same 
well known algorithms.  It's passwords that guarantee security, not the 
algorithm.  BTW, like hidden files, there is no security from obscurity.


As far as shelling to a third-party encryption program like gpg or 
openssl, those programs are good and produce secure outputs, depending 
of course on the algorithm selected.  However, the act of shelling 
exposes you to several attacks like man-in-the-middle.  Not recommended.


So internal encryption is recommended and Gambas has the gb.crypt and 
gb.openssl components to lighten your workload.  Also, gb.desktop has 
several password-related functions that can save and retrieve passwords 
from your system's wallet/keyring.


gb.crypt includes several one way hash algorithms like md5 or sha-256.  
With these, you save the password hash and then compare hashes on future 
logins.  With these, you never save the actual passwords and the hashes 
are virtually impossible to decrypt.


For two way encryption, where you need to go from plain text to 
encrypted text back to plain text, look at gb.openssl.  It has methods 
for symmetric encryption (one password to both encrypt and decrypt text) 
and for asymmetric encryption(two passwords, one to encrypt and one to 
decrypt).  Public key private key encryption is an example of the 
latter.  Text encrypted with the private key can only be decrypted by 
the public key and vice versa.

Re: [Gambas-user] How to stop a control raising events?

[Tony Morehen]

Careful, though, Object.Lock inhibits all events associated with a 
control, including events from internal controls.  For example, DirView 
has an internal TreeView control.  When you click on a folder or set the 
Current property in code,  DirView tells the TreeView to expand that 
branch.  TreeView then raises the Expand event, requesting that DirView 
fill in the sub-folders of that branch.  After that is done, DirView 
raises its click event.


I wanted the click event to only occur when the user clicks on a folder 
so I surrounded the code setting DirView.Current with 
object.lock/unlock.  All of a sudden, DirView stopped updating 
properly.  This seemed to occur only during the initialization of 
DirView.  It took me 2 days to figure out that the object.lock stopped 
the TreeView Expand event so DirView did not update. Another control was 
setting the DirView Current property during its initialization, not any 
of my own code, which made debugging even harder.


I wound up replacing the object.lock with a boolean flag.  When set, the 
flag stops the Click event code from running.

Re: [Gambas-user] Weather app in Software Farm

I just uploaded a version that uses the gb.gui component instead of

gb.qt5.  It also has a workaround that may fix your error. That error
arises when your system does not have a systray enabled.  See:

https://unix.stackexchange.com/questions/278104/app-icons-dont-appear-in-system-tray-on-linux-mint-17-3

I haven't been able to test since I'm running Manjaro.  What version of
Mint are you using : Cinnamon, Mate Xfce? 17.? 18.?

Hi Tony,

I tried your program on a computer at work and got it working after adding
*gb.qt4*. Linux Mint does not have QT5 yet. I tried it a home but even after
fixing QT I got: -

*"sni-qt/5871" WARN  12:51:31.765 void

After 20 seconds FMain appeared but with no data.

Not sure what the problem is.

  Dim sIn as String
  Dim sOut as String

  sIn = File.Load("/home/fernando/temp/deah001.dhn")
  sOut = Add11(sIn)
  File.Save("/home/fernando/temp/deah001.11Added.dhn", sOut)

End

Public Sub Add11(InputString as String) as String
  Dim bArray As Byte[]
  Dim String11 As String
  Dim i As Integer

  bArray = Byte[].FromString(InputString)
  For i = 0 To bArray.Max
bArray[i] += 11
  Next
 Return bArray.ToString
End

I am sure there is a way to do this efficiently in Gambas.Certainly not in
1 second, as it happened here, but perhaps in 5 or 10 minutes instead of
the several hours it is now taking.

Hi

I've found a file whose text has been obfuscated by subtracting 11 from
every byte. Now I want to bring it back to regular text. To do this I have
to add 11 to each byte read from that file. Now, I have tried several ways
to do it, and they all seemed every inefficient to me. Two examples follow











*j = 0For i = 0 To Len(RawText)str &= Chr(CByte(Asc(RawText, i) + 11))  '
either this or the following'Mid(Rawtext, i, 1) = Chr(CByte(Asc(RawText, i)
+ 11))Inc jIf j = 10 Then   Print i; Now   j = 0EndifNext*

In the first option (uncommented) I am building a new string byte by byte.
In the second option (commented) I am replacing each character in place.
I expected the second option to be way faster, especially because there is
no need for the string to be reallocated. Nevertheless, it showed to be a
snail.
The first option, in spite of the fact that it grows slower and slower as
the string grows, is still way faster than the second option.


To me it does not make sense. Does it for you?
Also, is there a faster way to do this?

Re: [Gambas-user] Pre-release of Gambas 3.10.0

[Tony Morehen]

I'll compile and start using it right away.  In the meantime, a feature 
request:


Currently, a menu item with children does nothing before displaying its 
child menu items.  I propose that the parent menu raise a click event 
before displaying its children.  This would allow you to show/not show 
enable/disable child menu items based on the current state of the app or 
its environment.


For example, when the edit menu is clicked, you can enable/disable the 
paste item based on the state of the clipboard.


This change should not affect existing apps as they will not have click 
handlers for parent menus.

It is my code.  It started off life as part of a cd ripper program I

read if

you
don't try to read the structure directly, but by each element of the
structure at a time.  Some tips:

1) Numeric elements (bytes, bytearrays, shorts, integers, longs) 
can be
read directly from the stream. ie  (4 byte Integer) = Read 
#Stream As

Integer.  Gambas can handle little endian/big endian issues.

2) Fixed length strings must be handled in a two stage process. 
First,
the required string length number of bytes is read into a byte 
array.

This
byte array is then converted to a string. Sample code:

Dim Bytes As New Byte[StringLength]
Bytes.Read(Stream)
FixedString = Bytes.ToString()

Note: Bytes.ToString stops the string conversion at the first 
null or at

the end of the array.  Therfore, you don't have to worry about
null-terminated strings.

v2 tags are more complicated, particularly since the tags can be 
ascii,
either kind of utf16, or utf8 encoding.  The code I sent has been 
tested

with over 10,000 mp3 files has seems to have no issues.

Re: [Gambas-user] reading files

[Tony Morehen]

I've attached an archive containing the code I use to read v1 and v2 MP3 
tags and other MP3 info including bitrates (fixed and VBR), sampling 
rates and number of channels.  v1 tags are pretty staightforward to read 
if you don't try to read the structure directly, but by each element of 
the structure at a time.  Some tips:


1) Numeric elements (bytes, bytearrays, shorts, integers, longs) can be 
read directly from the stream. ie  (4 byte Integer) = Read #Stream As 
Integer.  Gambas can handle little endian/big endian issues.


2) Fixed length strings must be handled in a two stage process. First, 
the required string length number of bytes is read into a byte array.  
This byte array is then converted to a string. Sample code:


  Dim Bytes As New Byte[StringLength]
  Bytes.Read(Stream)
  FixedString = Bytes.ToString()

Note: Bytes.ToString stops the string conversion at the first null or at 
the end of the array.  Therfore, you don't have to worry about 
null-terminated strings.


v2 tags are more complicated, particularly since the tags can be ascii, 
either kind of utf16, or utf8 encoding.  The code I sent has been tested 
with over 10,000 mp3 files has seems to have no issues.

Message.Question returns 2 if the message window was closed or canceled via

That is bad, especially if there are two buttons and the action should not be

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.

I have found and worked around the problem. When you do the following:

*Dim Expressions as string[] =

The last item pushed into *Expressions* is an empty string ("") even though
it DOES NOT exist
in the file. So, the expressions are compiled one after the other til the
last one, that is empty. Then the program crashes.

So it seems there is a bug in the *load.file()*. Bug that I was able to

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

Re: [Gambas-user] why this could not be? error in runtime?

[Tony Morehen]

It's difficult to say for sure what's happening without Piccaro's test 
strings.  However, 2 things do come to mind.


First, according to Gambas doc, InStr(strinchar, ")", -n) does a left to 
right search for ")", starting at -n  characters from the end of 
strinchar.  So if Instr doesn't find ")", it will return 0, which, in 
conjunction with the second -1, will cause mid to drop the last 
character of strinchar.  So to get the answer you want, use 
RInstr(strinchar,")"). which will do a right to left search for ")", 
starting at the end of strinchar.


Second, there may be a bug in gambas, or the documentation needs to make 
clear what end of string means.  This is best explained by example:


Instr("(foo)",")",-1) returns 5
Instr("(foo)f",")",-1) returns 5
Instr("(foo)ff",")",-1) returns 0

This means that Instr(s1,s2,-1) begins its search one character before 
the last character of the string.  So end of string actually means last 
character of the string and the docs should make that explicit or there 
is a bug if the intended meaning of end of string is the position after 
the last character of the string.

However the playground's editor does match the parentheses correctly. :)

Re: [Gambas-user] why this could not be? error in runtime?

[Tony Morehen]

Sorry about that,

What strings are you using?  What output do you want?  For example:
fn("(foo)") do you want "(foo)"  or "(foo"  yours returns "(foo"
fn("(foo)x") do you want "(foo)" or "(foo" yours returns "(foo"
fn("(foo)xx") do you want "(foo)" or "(foo" or "(foo)x" yours returns 
"(foo)x"
fn("(foo)xxx") do you want "(foo)" or "(foo" or "(foo)x" or "(foo)xx" 
yours returns "(foo)xx"


Let's get the algorithm right.  Then worry about bugs.

Instr("(foo)ff",")",-1) returns 0

This means that Instr(s1,s2,-1) begins its search one character before the
last character of the string.  So end of string actually means last
character of the string and the docs should make that explicit or there is
a bug if the intended meaning of end of string is the position after the
last character of the string.

Re: [Gambas-user] Shell command

[Tony Morehen]

Shane,

I can reproduce your crash here on 3.9.2.  It's cause is the line:

Settings["Options/stmDevice"] = ComboBox1.Current

If that line is changed to:

Settings["Options/stmDevice"] = ComboBox1.Current.Text

or the simpler, and in my mind preferred:

Settings["Options/stmDevice"] = ComboBox1.Text

The segmentation fault goes away.

So the code that I'd recommend you use (I commented the code changes):

Public sdevices As String


Public Sub SaveOps_Click()

  Settings["Options/CCompCLine"] = TextBox1.Text
'to fix the crash
  Settings["Options/stmDevice"] = ComboBox1.Text
  Settings.Save()
  Me.Close
End

Public Sub Form_Open()
 Dim d As String

   TextBox1.Text = Settings["Options/CCompCLine"]
   Shell "stm8flash -l" To sdevices
'  fill combobox with devices
'trim gets rid of the trailing "\n"
'moving Split into the loop saves an intermediate, unneeded string creation
   For Each d In Split(Trim(sdevices), " ", "", True)
 ComboBox1.Add(d)
   Next
'index = find selects the saved device
  ComboBox1.Index = ComboBox1.Find(Settings["Options/stmDevice"])
End

Re: [Gambas-user] Trouble with CSVFile Component

[Tony Morehen]

Did you add gb.utils component to your project?

Hi guys,

I'm trying to write a very simple program that pulls in one CSV File, and
spits out another, based on what's inside the file.

I see from the Wiki that there's a function for that, in the db.utils
component.  However, using the very sparse example provided, I'm getting
errors.

I'm using 3.8.4, which is the "current" version in my distro (Xubuntu
16.04.2 LTS), and the documentation says the feature was available as of
Gambas 3.7.

Here's the code I'm using:

Public Sub Main()

   Dim sCSVGrid As String
   Dim sCSVImport As String
   Dim hCSVFile As CsvFile
  
   
   
   Print "Enter the complete path and filename of the CSV file you are

importing"
   Input sCSVImport
   Print "Enter the complete path and filename of the CSV file containing the
grid you are creating"
   Input sCSVGrid
   
  
   hCSVFile = New CsvFile(sCSVImport)
   
   
   
End


Obviously, it's not doing anything yet, but this simple bit of code blows up
at

  Dim hCSVFile As CsvFile

saying CsvFile is an unknown identifier.

Yet, this code was taken from the example, I just added a few lines.

>From what I unerstand from the documentation, anything in db.util should be
available, but I guess I'm missing something, probably something simple.

As you can see, I'm a bit of a newb.   Any tips on what I'm doing wrong?

Re: [Gambas-user] Difference DateDiff(...) ?

[Tony Morehen]

You're right.  Print is not the problem.  Another part of Gambas could 
raise an error.  But Benoit is right.  Doing this kind of check is too 
resource intensive.  You're also right.  Since DateDiff(gb.second) will 
overflow for a ~70 year difference, over the longer term, it should 
return a long.  Since this kind of edge case is rare, it's not an urgent 
change and,in fact, may cause problems for existing code.



On 2017-08-06 02:27 PM, d4t4f...@gmail.com wrote:

Toni,

I don't think Print is at fault here at all. My guess is that DateDiff may need an 
"attitude adjustment" in these cases: It may need to either raise an overflow 
error or return a 64bit Long.

Hope this helps,
zxMarce.

The DIM AS LONG creates 64bit vars while DateDiff may return 32bit

data (don't have the docs with me).

Print will use 64bit to print the vars and 32bit with direct DateDiff

(you may confirm by using CLng to affect the DateDiff's in the second
Print)

Remember that when you have the most significant bit (MSB) set,

Gambas will interpret the value as twos-complement sign and yield
negative values.

what is the output of the shell line?  If you could post the complete

You could try this line:

devices = Split(sdevices, " ", "", True)

[Gambas-user] [CRASH REPORT] gbUDisk2

[Tony Morehen]

Hello all,

Damn, my program crashed Gambas this way :

1) Run the program
2) Plug in a usb drive
3) Click the mount button, mounts OK
4) Click the unmount button
Program crashes Aborted(6)
Console shows realloc error invalid old size

Background:
I'm writing a Udisks2 module that communicates with UDisks2 over dbus.  
It gathers drive info on existing drives and receives notifications when 
a new drive is plugged in, usb stick etc.

Two problems:
1) The crash above.  Note that unmount works if the usb drive is already 
plugged in.  Careful: the program defaults to unmounting /dev/sdb1.  
Make sure you use the right drive id.
2) The program intially sends some basic drive info to debug output.  
First, it prints the info item by item with no problems. Then it tries 
to print the same items in one print statement.  Some of the output is 
garbage.  What's worst, I've tried saving each info item to separate 
variables.  If I step through the assignments one item at a time, the 
individual assignment is at first correct. However, after the next item 
is assigned, the previous item's value also changes.  This looks like a 
buffer overrun or a stack overflow.

Re: [Gambas-user] [CRASH REPORT] gbUDisk2

[Tony Morehen]

#8173 seems to have fixed everything, including a crash when I enable 
dbus signalling, which I haven't brought up yet.  Now I have to figure 
out how to install 8173 to all my PCs


Some advice please.  Currently, I have many calls like 
DBus["system://org.freedesktop.UDisks2"]["/org/freedesktop/UDisks2/block_devices/sda1", 
"org.freedesktop.UDisks2.Filesystem"].MountPoints. (status quo)


I can replace it with new approach 1:
Private $DBusApp As DBusApplication = New DBusApplication(MyDBus.System, 
$Application)


mnt=$DBusApp["/org/freedesktop/UDisks2/block_devices/sda1", 
"org.freedesktop.UDisks2.Filesystem"].MountPoints


or even new approach 2:

Private Proxy as DBusProxy

Proxy = $DBusApp["/org/freedesktop/UDisks2/block_devices/sda1", 
"org.freedesktop.UDisks2.Filesystem"]


mnt=Proxy.Mountpoints

What would be your preferred approach? I know that the DBus class caches 
DBus Applications so that there doesn't seem to be any resource 
advantages to new approach 1.  New approach 2 will require 2 proxies for 
each drive, one for the Filesystem interface and one for the Block 
interface.

After a bit of searching, I found that the offending code can be

this single line :

Print 
DBus["system://org.freedesktop.UDisks2"]["/org/freedesktop/UDisks2/block_devices/sda1", 
"org.freedesktop.UDisks2.Filesystem"].MountPoints


It appears this property gets translated to a Byte[][], but the 
interpreter crashes
when trying to create one from the native components, because the 
class's symbol table

is not initialized yet (as object classes are created dynamically).

However, creating one from Gambas code works, and in fact, creating 
one before

the D-Bus call makes it not crash anymore :

   Dim x As New Byte[][]
   Print 
DBus["system://org.freedesktop.UDisks2"]["/org/freedesktop/UDisks2/block_devices/sda1", 
"org.freedesktop.UDisks2.Filesystem"].MountPoints 'works!


Now you have a workaround, for until this is actually fixed. :)

Regards,


Is it better with revision #8173?

Re: [Gambas-user] Git compilation report

[Tony Morehen]

I'd recommend for a very clean make:

cd gambasdevel
sudo make uninstall'really only needed on a version change or your 
compilation is likely
'to include different ie fewer 
components

make clean  'get rid of all the generated or backup cruft
git clone --depth=1 https://gitlab.com/gambas/gambas.git gambasdevel
'no need for all the previous versions
./reconf-all && LLVM_CONFIG=llvm-config-3.5 ./configure -C
make && sudo make install

To just update to the latest revision (there must be no changes to the 
configure.ac or Makefile.am files.


cd gambasdevel
git pull'watch for changes to configure or Makefile
'if there are do ./reconf-all && 
LLVM_CONFIG=llvm-config-3.5 ./configure -C

make && sudo make install

When updating:

Unclear part (see below)
./reconf-all && LLVM_CONFIG=llvm-config-3.5 ./configure -C
make && sudo make install

Unclear part:
I run the git pull command as Charlie suggests?
Or git checkout master as Christof seems to suggest?
I have never used make clean when need to use it?
Would it be the same as rm -rf gambasdevel /?
I note that the command:

git clone --depth=1 https://gitlab.com/gambas/gambas.git gambasdevel

Download only the latest version of development and not the whole git, as
explained in the wiki (about a third of the 100MB)

Even if Piccoro does not approve?


i already said the same, do not update, alway remove previous install and
made again!

Removing the last installation (make uninstall) is neccessary but not
deleting the whole repository with the Gambas sources every time!!! That
would be bullshit.


Alles Gute

It's Gambas mailing list, do we care? Also nabble already publishes the
mailing list content.




3) Google brutally stopped their issue tracker. I had to make an issue

they won't stop Google groups brutally too.


Yeah, bad policy from google, but this is quite hard requirement to

I was using Breeze Dark and it was responsible for the invisible scroll

Tony MOREHEN reported a new bug.

Summary
---

Paste doesn't work in gb.form.terminal

Type : Bug
Priority : Medium
Gambas version   : Unknown
Product  : Unknown


Description
---

When running terminal.exec(["bash"]), the paste method does nothing, even 
though the clipboard has 'plain/text' content

Cause:  line 924 in TerminalView.class --
If Not $hProcess Or Not $hPipeOut Then Return
-- will return either or both $hProcess or $hPipeOut are null.  It should 
return only when both are null.

Correct:
If Not $hProcess And Not $hPipeOut Then Return

I've attached a patch to fix.  The patch also adds a SendText method to 
gb.form.terminal.  This allows the containing application to send commands to 
the terminal process or pipe.

I saw that.  As far as I could tell, it's identical to the gnome 
discussion.  Including having the hints category and urgency discussion 
before the hints chapter!

Re: [Gambas-user] Class Implementing DBus Notifications

[Tony Morehen]

1)  I tried to be as agnostic as possible.  The reference to the Gnome 
developer's specification is there because it is the only one available 
on the web.  There is not even one on freedesktop.org.  It is my 
understanding that modern DEs conform to that spec, including KDE, 
Gnome, Cinnamon, XFCE etc.  If the server supports a current libnotify, 
then is should support my code. Btw, I'm running Xfce on Manjaro.  Wrt 
Icewm, Icewm has not been updated since 2011.  It probably implements an 
old version of the spec.  People have my code they can change to suit 
their needs.   I recommend D-feet as a Dbus explorer, so people can see 
what application names, paths and interfaces to use.


2) Yes, this was a slip on my part.  My daemon returns the 4 parts that 
I coded for, but in the back of my mind I knew that only 3 were 
official.  I've changed the code to make SpecificationVersion optional.


3) I've added 0 = no timeout to the comments on duration. Another 
oversight.  Yes, some daemons ignore the Duration variable.  In fact 
they can ignore almost any of the Send parameters.  So providing a value 
may be wishful thinking, but at least it won't generate an error.


4) You're right, you can use standard icon names.  I've renamed the 
property to IconNameOrPath and the comment to reflect this. I'd insisted 
on full path because that was the only thing that worked for me.  The 
iconname I was using was drive-harddisk-usb, which is an icon in my 
theme.  It turns out that is a non-standard icon and so needs a full 
path to work.  When I shortened it to drive-harddisk, the simple name 
worked.


5) NotifyID is supposed to be a unique unsigned integer, starting at 0 
and increasing by one for each notification message that occurs during 
the session.  You need such an Id to replace a current notification or 
to close an open one, particularly a non-expiring one.  In my system, 
that is exactly what occurs.  For example, in my AutoMount program, when 
I plug in a drive, device added pops up, which is then replaced by drive 
mounted.  I use 2 separate notifications because mounting can take some 
time.


Anyway, attached is a revised class.

Thanks, for that Tony, some good stuff in there (the least of which is 
that damned "hints" collection!) Since my original post and everyones 
comments I have spent more time reading than doing. So a few comments 
(in the most sincerest mode possible).

1. We (gambas "we") should strive for agnosticism. This class is very dependent on some specific implementations of the so called 
gnome "standard" which is turn looks very much like the "specification" for the (lousy) notify-osd daemon. 
("lousy" because it was dumbed down so far that even Shuttleworth could understand it.) Your class is dependent on the 
notification daemon that is running on a machine to a) use DBus messaging the way those (ahem) standards and specifications state.  DE's 
that use non-compliant notification daemons are not supported by your code.  This is not a biggy, But one has to take care. Secondly, you 
are relying on the daemon DBus interface being called exactly "org.freedesktop.Notifications" which is fine for all the common 
ones but I did find one today (might have been for IceWM - can't remember?) that registers as "org.freedesktop.notify".

2. (Very specific) the code at line 114: result.Add(sa[3], 
"SpecificationVersion") is very specific to notify-osd. All the so called 
standards only refer to 3 required items being returned from GetServerInformation.

3. This "duration" parameter seems to be supported/interpreted/used/abused willy nilly by different 
daemons. In general, it "appears" that a value of 0 tends to indicate a non-disappearing 
notification (but then again sometimes not). It "appears" that a value of -1 is generally used to 
do whatever the daemon designers thought might be a good idea. It appears that other values may or may not be 
used as a timeout period.  In short,
apart from the actual libnotify library (which after all is only going to pass that value 
on to the display daemon) its' use is rarely "the timeout before a notification is 
closed" ( without user interaction).

4. One thing I did find that was quite good and apparently generally broadly implemented is the use of the so 
called "standard" desktop icon names e.g. instead of passing a fully qualified path to a specific 
icon you can send one of these "names". For example, setting IconPath to, say, "task-due" 
will use the task-due picture depending on the users actual active icon set. The names are at: 
https://specifications.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html#names

5. Question: In the (little) amount of playing around today I am having trouble with the 
"replaces_id" parameter for the notify method, i.e your $iLastNotifyID returned 
by the Notify function.  All I ever seem to get back is zero?? The Ubuntu spec (for 
notify-osd) seems

Re: [Gambas-user] More DBus queries - signals

I see nothing amiss in your code.

This is the code I use for a DbusObject.  It is used to control a 
desktop menu application.  Note the event declaration.  DbusObject is 
missing, but implicit to the class.  I raise the event the same way you do:


  DBus.Raise(hDbusObj, 
"org.ajmconsulting.gbmenu.App.StartupNotification", [$key, pid])


$key is a AppName.desktop file, pid is the id/handle of the process just 
launched.

for the last few days I've been raising DBus signals simply by calling 
something like:

 being a DBusObject child object

This seems to be working fine. Am I doing something unsupported that is likely

Re: [Gambas-user] Balloons, everywhere but when I don't want them.

[Tony Morehen]

BTW the attached code is not fully functional.  It tries to listen for a 
signal on both the system bus (Udisks2 signal) and the session bus 
(Notifications).  Unfortunately, Gambas can only listen to one bus at a 
time, the second declared bus is ignored. As a result, the code that 
responds to the Notifications signal is never called.


I've opened a bug report (1132) on this issue.

Sounds like a feature of your DE (and I'm not good with DEs) but a quick
search suggests something called libnotify for sending desktop 
notifications.
It is said to be toolkit- and desktop-independent, but you need a 
conforming
notification daemon running -- which you may already have, if you can 
see
notifications from other programs (assuming they use the same 
machinery).


So, I guess you would need a gb.libnotify component (it really 
doesn't look
hard to do, there's only maybe 3 dozen functions in the library and 
it seems

you only need as few as 5 of them to show your first notification).

If you can't do that, there seems to be a tool called "notify-send" 
which
looks like it lets you access all the library features via the 
command-line.
That said, notify-send does nothing on my desktop, probably because I 
don't

run a fancy notification server...

Re: [Gambas-user] Support for IMAP in gb.net.curl

[Tony Morehen]

Just a quick update on an Imap class.  The following methods have been 
implemented and, for the most part, tested:


Abort, AddMessageFlags, Authed, BuildSequenceSet, Capabilities,
CleanUpMailBoxList, Connect, CopyMessage, CopyMessages, CreateMailbox, 
Debug,

DeleteMailbox, DeleteMessage, DeleteMessages, Encrypt, Exec, Expunge,
FindValue, GetMessage, GetMessageFlags, Host, LSub, List, ListMailboxes,
ListSubscribedMailboxes, Logout, MailboxInfo, MailboxStatus, 
MoveMessage, MoveMessages, Noop, Password, Port, RemoveMessageFlags,

RenameMailbox, Search, SelectMailbox, SetMessageFlags, User, Welcome

The testing has been done on a static email account.  As a result, copy, 
move and delete messages have not been properly tested.  I'll follow up 
on that in another message.

Re: [Gambas-user] Support for IMAP in gb.net.curl

[Tony Morehen]

To support a dynamic email account (one with new messages and deleted 
messages) and to implement the Idle and Notify commands, I need to 
handle server notifications.  What I plan to do is implement a monitor 
loop which will do a readline on the input from the server.  Each new 
line will be tested to see if it is a notification.  If so, the 
appropriate action will be taken.  If it's not a notification, it will 
be printed to a buffer stream. Currently, commands are directly sent to 
the server socket and replies are read directly from the same socket.  
In the new approach, replies will be read from the buffer.


One complication is that I must ensure that all the CRLFs in the buffer 
must remain intact.  Another complication is that I cannot just do a 
readline on a blocking stream.  There maybe some time between 
notifications, which would normally cause the readline to timeout.  Idle 
and Notify commands can wait for 20 minutes or more.


Comments? Suggestions?  I'd really appreciate advice on the best way to 
handle this.

Re: [Gambas-user] Support for IMAP in gb.net.curl

[Tony Morehen]

I came across an interesting issue when working on Imap's Fetch 
command.  Fetch is used to down load messages.  The response to a Fetch 
has 4 parts:

1) a single line providing the size of the download, say, 69000 bytes.
2) the mime-encoded download (a string 69000 bytes long)
3) one line whose only contents is ")"
4) one line status line.

So my code does:
Readline
response = Read #stream, iSize    'iSize=69000
Readline
Readline

Using a TCP socket,  the Read # line has no error but the download is 
incomplete, say only 5 bytes.  The remaining 19000 byes is read by 
the next Readline.  However, the response variable is the correct 69000 
bytes in length, with the last 19000 bytes zero-filled.  Its like the 
Read # timed out but the timeout is set to 1 and 10 seconds had not 
elapsed.  Socket.blocking was set to True.


Using an openssl process, the Read # line raises an error:  Error 9, Bad 
file descriptor.


I have a workaround:  Read # is replaced with

  Dim result as new String[]

  Bytesread=0
  Do While BytesRead < iSize
    Response = Read #$hStream,  IIf(iSize - BytesRead > 4096, 4096, 
iSize - BytesRead)

    result.Add(Response)
    bytesread += 4096
  Loop
  Response = result.Join("")

Now both TCP and openssl work, no zero-fill no errors.

Any ideas? Other fixes?

Re: [Gambas-user] Fwd: [Gambas Bug Tracker] Bug #1196: Socket Lof returns 0 when data is available.

[Tony Morehen]

That fixes both polling and events.  Great work. and quite the turnaround!

The change makes sense.  I read the original code as testing the actual, 
physical socket while the revised code effectively tests a virtual 
socket with responses buffered to the stream.


Unfortunately, the fix does not affect the no events problem I have in 
the serversocket class.  In the ClsServer.class of gbDummyImapServer, 
the Socket_Read event is only triggered when line 35, the 
Object.Attach() line is included.  Comment out that line and 
Socket_rRead is never called.

Sorry, it doesn't work for me.  In fact, my test program receives no 
signals at all.


I'm working off what at the time was the latest commit, 
a2183117ffd8448b10008f76e7dac6eecd01cc3d


I've attached the test program.  To use, just insert or remove a usb 
drive and watch the debug messages.


BTW I replaced /usr/lib/gambas3/gb.dbus.so.0.0.0 with the same file from 
my previous build and the test program received the signals ok.

Re: [Gambas-user] Fwd: [Gambas Bug Tracker] Bug #1161: Class Editor is Locked

[Tony Morehen]

Some more questions / things to try:

1) Copy the project folder elsewhere in your home directory, but not in 
the dropbox tree.  Try to edit.

2) In the copied folder, run chmod --recursive a+w *.  Try to edit.
3) Try creating a new module, class or form.  Try this in both the 
copied folder and the original.  Try to add code and edit the new module 
etc.

4) Can the problems be related to dropbox.

Agreed. But so far, this understanding has not helped me to find a solution.

What directory is your project located?  Have you tried copying the project

It is on my home directory (everything is under

/home/fernando/Dropbox/Gambas/*"). Directory Dropbox is a local directory
that is replicated by Dropbox so I have a copy available in other machines
that respect the same structure).

In the vm, is Gambas loading the project directly from the original

directory or from a copy in the vm.


Yes. In the VM Gambas works with the same files directly. The
above-mentioned directory is mounted on the VM so Gambas sees them as local
files (local to the VM).

Does your system enable extended ACLs?  Are you running AppArmor or

SELinux?  What about in the vm?


Not running AppArmor or SELinux. Extended ACLs not enabled.

OS running on the physical machine is precisely the same that runs on the
virtual machine. I install them both from the same source and give them the
same configuration. For instance, now I am running Linux Mint 18.2 on the
metal and, under VirtualBox I have the same Linux Mint 18.2 (technically it
is not a clone, but it looks a lot like it).

I've never tinkered with it. Also, IDE used to work. All of sudden, it
stopped working.
I had changed nothing between the working stage and the non-working stage.
Besides, when I install the virtual machines, I use the default input

Perhaps you can provide me with a command to find out what input method I

The nearest I got to it was by looking into the files at /etc/X11/xinit.

Re: [Gambas-user] Support for IMAP in gb.net.curl

[Tony Morehen]

There's not much logic behind the 4096.  It was the first number I tried 
and it worked.  I originally used 4096 in a copy routine in a file 
manager program.  There, 4096 makes sense as it equals a hard drive 
cluster size.

2) the mime-encoded download (a string 69000 bytes long)

4) one line status line.

So my code does:
Readline
response = Read #stream, iSize    'iSize=69000
Readline
Readline

Using a TCP socket,  the Read # line has no error but the download is 
incomplete, say only 5 bytes.  The remaining 19000 byes is read 
by the next Readline.  However, the response variable is the correct 
69000 bytes in length, with the last 19000 bytes zero-filled.  Its 
like the Read # timed out but the timeout is set to 1 and 10 
seconds had not elapsed. Socket.blocking was set to True.


Using an openssl process, the Read # line raises an error: Error 9, 
Bad file descriptor.


I have a workaround:  Read # is replaced with

   Dim result as new String[]

   Bytesread=0
   Do While BytesRead < iSize
 Response = Read #$hStream,  IIf(iSize - BytesRead > 4096, 4096, 
iSize - BytesRead)

 result.Add(Response)
 bytesread += 4096
   Loop
   Response = result.Join("")

Now both TCP and openssl work, no zero-fill no errors.

Any ideas? Other fixes?




I looked at the gb.net socket source code (which I didn't wrote), and 
things are clear: the read method of the Socket class stream just do 
one system call. So it does not read what the user asks, but what is 
available on the socket.


Other streams implemented in the interpreter (like pipe, for example), 
on the contrary, try to read the number of bytes requested by the user.


Your code implements the missing logic in gb.net, so it fixes the 
problem (as 4096 may be the granularity of TCP data that is sent to 
the user space).


I have to fix that directly in gb.net. Of course it's a pity that each 
stream has to implement the same logic, so maybe I should take more 
time to see I can find a solution directly in the interpreter.

Re: [Gambas-user] Support for IMAP in gb.net.curl

[Tony Morehen]

Benoit, the Read issue is resolved.  I tested using both the the 
existing code, with the read loop and the original code where it tries 
to read the entire message at once.  Both work for both a TCP connection 
and an openssl connection.


However, the send comand for a TCP connection raises a socket closed 
error.  Not right away, but after several send commands. It seems to be 
a timing issue, the error is not raised when I step through the code.  
The send command is simply:


Public Sub Send(Data As String)

  Print #$hStream, Data

End

There is no error at all using an ssl connection.

Hi, Tony.

I have just pushed the 'rework-stream-interface' branch to the gitlab

I have reworked the internal interpreter stream interface, so that 
incomplete reads are retried automatically until all the data is read 
or an error occurs, whatever the underlying stream.


Can you try it and tell me if it fixes the incomplete read on TCP 
sockets?

[Gambas-user] Class Implementing DBus Notifications

[Tony Morehen]

As promised, attached is a heavily commented class implementing DBus 
Notifications.  It is a complete implementation of the specification.  
There are two approaches to using the class:


1) fill in the properties and call SendNotification:

Dim hDbusNotify As New DbusNotify
hDbusNotify.Summary = "Device added:"
hDbusNotify.Body = "/dev" &/ device
hDbusNotify.FullPathToIcon = icon
hDbusNotify.Actions = [""]
notifyID = dbusNotify.SendNotification()
mount = UDisks2.Mount(device)
hDbusNotify.Summary = "Device mounted:"
hDbusNotify.Body = "/dev" &/ device & " to " & mount
hDbusNotify.Actions = ["browse=" & mount, "Browse"]
hints.Add(2, "urgency")
hDbusNotify.Hints = hints
hDbusNotify.Duration = 5000
notifyID = dbusNotify.SendNotification(notifyID)

2) Use the Notify function directly:

Dim hDbusNotify As New DbusNotify
Dim hints As New Collection
hints.Add("device.removed", "category")
hDbusNotify.Notify("Device removed:", "/dev" &/ device, icon, 
[""], 0, hints, 5000)


DbusNotify raises 2 events:

Public Sub dbusNotify_ActionInvoked(iNotifyID As Integer, sActionKey As 
String)


  If Left(LCase(sActionKey), 7) = "browse=" Then
'want to ensure a trailing "/"
sActionKey = "file://" & Trim(Mid(sActionKey, 8) &/ " ")
Shell "xdg-open " & sActionKey
  Endif

End

Public Sub dbusNotify_NotificationClosed(iNotifyID As Integer, iReason 
As Integer)

'Usually ignored
End



dbusNotify.class
Description: application/java

Re: [Gambas-user] New domain name for Gambas

another option is perhaps to take over the gambas.guru site. It seems to

Personally I've been thinking about something like gambas-basic or

This way it's much more readable and easy to type in.

gambashq looks nicer, but it isn't really obvious what HQ is. (And to

Re: [Gambas-user] [Gambas Bug Tracker] Bug #1136: ColorButton fails with error bad drawing under gtk2 and gtk3

[Tony Morehen]

Sorry, I realized after I uploaded the project that I uploaded a version 
using a customized DirView.  Is there any way to delete the gbTerm I 
published to the Software Farm?


My version of DirView has some new events and properties.  It is 
otherwise 100% compatible with the standard DirView.


ShowFiles(boolean) True shows the files contained in the current folder.
FoldersFirst(boolean) When files are shown, sort folders first
RootName(string) Change name of root ie change "/" to "System"

Event IconByType(sPath As String, iIconType As Integer)
Raised after Icon event, sPath is the same as Icon's sPath, iIconType 
type of icon to supply 0=file, 1=closed folder, 2=open folder


I'd be happy to contribute this component to Gambas.

If you put an exported DirView class in your project, it will 
automatically inherits and override the gb.form DirView class. That 
way, you can enhance the DirView and publish your project without 
having to wait for your changes to be merged.

I thought some more about what you wrote and I tried:

1) Created a Main module and set it as the startup class.
2) Moved FMain's _new code (setting up signal handlers etc) to Sub 
Main() in module Main

3) Moved all other code into Main
4) deleted FMain and removed all components except gb.DBus and gb.base

Everything worked.  I have my daemon with a minimum of memory overhead.  
Brilliant!

There is always an event loop in Gambas programs. It starts as soon as

Re: [Gambas-user] Fwd: [Gambas Bug Tracker] Bug #1161: Class Editor is Locked

[Tony Morehen]

Fernando,

The fact that Gambas runs properly from a vm strongly suggests that the 
problem is not Gambas, but is the system environment that Gambas is 
running in.


What directory is your project located?  Have you tried copying the 
project to your home directory?  In the vm, is Gambas loading the 
project directly from the original directory or from a copy in the vm.


Does your system enable extended ACLs?  Are you running AppArmor or 
SELinux?  What about in the vm?

Besides, when I install the virtual machines, I use the default input

Perhaps you can provide me with a command to find out what input method I
