if i remember correctly EXEC is an interface to the exec family of syscalls. so
writing EXEC
["killall prgname"] will result in the program "killall prgname" to be
executed. i suggest that none
of your programs is named like that (i can't interpret the error message for it
is not in the manual
of the exec family of functions, so i may be wrong with all this). you could
try using EXEC
["killall", "prgname"] which will call the program killall with "prgname" as
parameter.

tobi

NCurses.On()
NCurses.Print("this is text", 10, 10)
NCurses.Attributes = NCurses.Bold Or NCurses.Reverse
Print " this is a brave test."
NCurses.Print("next line", , 11)
NCurses.WaitKey()
NCurses.Off()
End
-
but as the docs about programming components in c/c++ reasonably say, this is
rather c-style and
not suitable for the gambas language. (at the moment, there is one static
object NCurses - i want
to discover the api further before writing any serious classes).
the Print() _function_ takes optionally x,y coordinates from which to print the
text using ncurses.
i thought, it would be better to just use the Print instruction to print text
instead of this
function all over again - this is just not aesthetic (but bearable?).
while the Print _instruction_ works fine for that - tried also with multiple
ncurses WINDOWs
present - it always prints after the current cursor position, no matter what's
there. that's the
same with the ncurses functions, the main problem is that i turned on some
attributes which are
handled by the library, too. the text from the Print instruction doesn't get
bold and video reversed.
consequently, one may never use Print instruction to stdout in ncurses mode and
this option has
departed...
i had the weirdest ideas of redirecting stdout, to which Print prints, to a
stream object inside the
ncurses component, reading from that and printing the data with the ncurses
functions, but that's
quite too strange...
any suggestions/ideas about a suitable interface for something that
fundamental? or may the above
code fit? (i appear to not often use the ncurses mvwprintw() in any bigger
thing without having
built a wrapper around it or controlled it via a loop, so this may really fit
as is...)

tobi

actually, it should, there is no difference between "normal" and hidden files.
it works for me.
maybe you messed around with the variable? try
Print File.Load("~/.applica...")
to see the content, it really should work.

wow, mail citation gets weird now.
could we quickly recall? to clarify things to me, too... this all works as
expected (gives True):
Print Exist("~/")
Print Access("~/", gb.Read)
and
Print File.Load("~/")
insistently fails?

[Gambas-user] Excluding components from build process
Hi, I know a pretty bunch of components that I don't intend to compile on my system (because I don't want my box to satisfy their dependencies). May it be possible to explicitly exclude them from the reconf-all, configure, make process? I know that despite the make part this is a quite rare task but nevertheless a pain on my machine. I'm not very familiar with those autoconf and friends and seriously: The files they generate are unreadable, at least to me. I don't want to steal someone's time (the dictionary says, the correct idiom would be something with monkeys?) explaining me what goes on but a yes/no/look at the stuff answer.

[Gambas-user] Regexp based highlighting
Hi, it's some time since I last used the Highlight class together with the gb.qt4.ext Editor and I personally found it quite painful in the beginning. I hope, I did nothing wrong when I constructed a large Editor_Highlight() handler? However, my question is about a Regexp based Highlighting. Does it already exists? A sample I can provide for that, is vim. I think about implementing that (at least) when I extend the gb.ncurses component to TextBoxes and stuff (what the ncurses forms library provides), it may be of help in the GUI world, too, I'm almost sure. Remarks? (From Benoît perhaps? I saw that there exist several Highlight* classes that do the job for quite some languages, so I _suppose_ that there's no such automatism?)

[Gambas-user] Using qsort with Objects
Hi, I want to sort an Array of Arrays as Variant[][] that may contain different datatypes in each member of an array but the arrays are all homogenous (think of a Database, it's not the actual subject but the same idea). That's what I thought of: - Write a class that Inherits Variant[] (that will act as the Array containing Variant[], so I could also Inherits Object[]?) - Create a Sort() method for that class that takes an integer N for the member to sort by (Variant[][N]) (When Inherits Object[], I get error messages on incorrectly overriding Object[].Sort(). The parameter?) - Call qsort(Super.Data, Super.Count, SizeOf(gb.Pointer), MyCompare) -- _Right?_ - MyCompare consequently takes two Pointers. How may I treat them as being references to Variant[]? Any casts possible? After that, it would be easy to use TypeOf(Variant[][N]) and call a datatype-specific routine to compare the two values. I tried to Private Sub MyCompare(V1 As Variant[], V2 As Variant[]) and got a Segfault after one line of wrong results when, in MyCompare, Print V1[0], V1[1] which are valid.

Segfault comes from gbx_class.c:1358: array_type->array_class = class; but before that in the same function: CLASS *array_type = (CLASS *)class->array_type; and look at: (gdb) print class->array_type $2 = 12 which is GB_T_VARIANT, as supposed to be since I exported a Variant[]. I think creating that as a pointer is a bug. (Creating arrays of native datatypes not expected?)

Concerning the preprocessor... What about utilising the cpp just as a command
that runs over each
class and module file before seen by the compiler code? It's already powerful
enough or is that
too much for gambas? (It would break existing code due to character case in the
gambas preprocessor
directives...)

But just for interest, what do you mean by "impossible to analyze"? Excuse me, but I haven't read anything from the compiler yet. (When you say "analyze", I think of line numbers and stuff (optimisation can be done later, too, right?), but line numbers would be possible, I'm almost a bit certain, to report to the IDE, if that is what you mean) I just tested it and found that cpp warns at ['] the gambas comment character which, of course, may not ahve any closing ['] one and thus confuses the program but it fearlessly ignores that and continues as expected.

Used by people at least a bit familiar with the basics of the cpp won't have any problems, the only thing is the translation of the cpp line control which I have discarded gracefully using sed because I don't make any mistakes ;) It's clear that it would slow down the compiler and that most people won't need those fancy tricks as gambas is basic and has advanced enough compiling mechanisms, I'm convinced, but: a simple line on the top of a file to enable the cpp for the rest of people that may utilise it wouldn't hurt?: ' Gambas class file ' :use cpp Please, explain your worries. A more intrusive "feature" would be the ability of using that c-/c++-style comments /**/, // within gambas when cpp'ed...

[Gambas-user] Announcement: gambas-buch.de officially started
Hi gambas-users, at http://www.gambas-buch.de you will find a website on which a book on the Gambas programming language will be published. After over 3 years of intensive research, now the first chapters are published. We place value on good description of the classes and components of Gambas as well as on the practical implementation of the theory in concrete Gambas projects. For each document, there is a PDF version to download and all the projects referred to and built from the article. Progressively, all projects will be ported to, developed and tested in GB3. The authors hope for animated cooperation with the readers of the online book. A contact form is available to receive comments and hints and to improve the texts and projects at place. Best regards, Hans and Tobias -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

(Although, I find it rather powerful apart from C) I didn't know the preprocessor was responsible for these nifty things.

I have never tried to run gb.ncurses in the IDE and I suppose further that it would not work since ncurses wants a terminal to run in - AFAIK - and I really can't say if the IDE console is a PTY or something that ncurses accepts.

Sorry, haven't read the subject entirely when I first saw the incoming mail... So you expect this output in the window, right?: o ndo a Mundo H Hol Hola Mu ol So my question bounces to Benoît: It's said in the docs that the three string functions used above are optimised so that they don't duplicate strings. Does that mean or is it a general fact that I cannot rely on the STRING() macro to extract a NUL-terminated string from a given GB_STRING argument? At least there doesn't seem to be a NUL byte which causes the component to print everything that follows until the end of the original string... Brief explanation and after lunch, it's done.

[Gambas-user] Strange file modes
Hi, some time ago, I noticed in the sources file modes that appear strange to me: [gambas3]$ find . -executable -type f -regextype egrep -regex '.*\.(c|h|cpp|hpp)' -printf "%M\t%P\n" -rwxr-xr-x main/lib/option/main.c -rwxr-xr-x main/lib/option/getoptions.c -rwxr-xr-x main/lib/option/getoptions.h -rwxr-xr-x main/lib/option/main.h -rwxr-xr-x main/gbx/gbx_local.h -rwxr-xr-x main/gbx/gbx_subr_file.c -rwxr-xr-x gb.xml/src/xslt/CXSLT.cpp -rwxr-xr-x gb.xml/src/xslt/CXSLT.h -rwxr-xr-x gb.xml/src/xslt/main.h -rwxr-xr-x gb.xml/src/xslt/main.cpp -rwxr-xr-x gb.qt4/src/CContainer.cpp There may be more... I just wanted to filter away the shell scripts and stuff that ought to be executable (that's what I mean by "strange file modes" because I don't think those files above have to be executable) quickly. I noticed them only on C/C++ source files, so far and you see, there are a few (that's why I decided to search for those in the above command). Nothing interesting but sometimes I startle up when listing directory entries :) (One may improve the command line and filter out the scripts used by the build system by their names or something if this is really considered a security issue - I don't think so but I'm, too, not very familiar with what could be done.

If you use the WAIT instruction, the interpreter re-enters its event loop. Only in this loop, changes to the GUI are made effective. So just call Wait without any parameter so that the interpreter spends only as long there as it needs to process all the pending events and refresh the GUI.

I was once working on reversing the collatz conjecture from a given integer - using a (halfways) binary tree. Graphs would in fact be interesting to implement but what is to be cleared up before anyone could think about volunteering: * Are trees restricted to their number of children? * The same for graphs: restrictions on the number of edges?

You presented a b-tree above, this appears generic to me... I certainly lack theory on those things. But shouldn't it be less annoying to get to level 3 than "Root.left.left.left" ? There are a lot of purposes and designs of trees (graphs), right? To implement a certain idea would not be too difficult but instead to implement only one of those as a generic tree (graph) which is then able to be inherited and specialised, maybe in gambas, - that's what I find difficult (no wonder without theory).

So there has to be _one_ node class for the generic node above (that can possess both attributes) that implements methods which resemble the tree algorithms. That way we could have a basic tree datastructure - if it is that simple. This basic datastructure can be inherited, overridden, etc. If the node class is aware of these both attributes (being root node of a tree and itself node in a tree at the same time) one can easily concatenate trees and that's what I wanted to show with my code above. (Sorry if I re-invent the wheel here) What you were out for, if I got you right, was only providing a datastructure for nodes and a separate class with code to handle them?

The word can be another one down there, it is the highest school graduation level here and really far from painful, almost simplistic. But back to the topic. It would be nice if there was someone to implement that natively. I'm not going to promise anything but I have a book lying around here with a relatively short chapter on graphs (and trees) and almost half a week of holidays left... :) If only, it could be preliminary work to gb.datastructures (even if I find that the name could be improved) Regards, Tobi -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

There are passed through a function that selects the debugging functions by identifiers (strings would be best, I think). Depending on what is possible with the current debugger, parameter(s) are required (pointers? names?) and a way to obtain them from the debugger over there (this could be the only addition to the debugger process interface). The socket over there writes back the data so that the IDE here can display the stuff as if it was received from the debugger... This is a technically not that complicated protocol, I think.

If you are running, the lockfile exists, when program terminates, it removes the file. I suggest to deliver a script to remove that lockfile in case of application crash (I wrote such a thing for the firefox at our school because students seem to either manage to crash firefox very often or login as the same users all the time). You can create that file on whatever scope you want it to act in, like per user, e.g. in their home directories, or system-wide, e.g. in /tmp.

Benoît stated back then that only the really needed features will be implemented in the Gambas Preprocessor and scolded me for my proposition to use the CPP instead. Nonetheless, if you really want to use the #include directive and other c-style things in your own dark chamber, nobody would care if you maintain your sources split, merge them via #include and then push them through the gbc3. As indirectly quoted above, it is not a solution for future gambas and I would strongly prefer OO over this but if you need it, why not... Uhh, too late to respond to Randall's last post but I totally recommend his last point.

Yes, I was surprised, too, when I saw lately how gb.desktop grew since I last
had a look at it.
There seem to be a lot of people who want to run programs as root, it's always
the same problem to
solve...
I don't know about the scripts, I personally didn't need them so far but they
are distributed in the
gb.desktop/src/gb.desktop/xdg-utils/ directory in the source tree. If there is
a bug, you might be
able to spot it yourself - at least xdg-su seems not really complicated, even
to me who is not used
to shell scripting to that extend.

Tobi

To address Benoît's recent thought: Why not have a form like this: +Run as Root-+ || | Choose method: [ComboBox:] | | | Sudo | | | | Su| | || | Password: [TextBox...] | | [Button: OK] | ++ This way, the experienced, aware user could choose (not really if it was detected by the class that no "sudo" was found in PATH...) and the others most likely have sudo installed. It would equally well end the discussion of the preferred graphical frontend - only disadvantage I can see: in this draft, there is no configuration possible, except for the method of privilege elevation.

[Gambas-user] Signal #11 when overriding Variant[] - Bug revived?
Hi Benoît, this afternoon, we discovered that with a newer revision the program I wrote to demonstrate sorting of multi-dimensioned Variant[] broke. I again get Segfault when exporting an overridden Variant[] class from my project (wasn't there a discussion about this recently?) When I developed this program, I reported a bug which results in a Segfault that was fixed in rev#4715. This seemed to be the result of [main/gbx/gbx_class.c] --8<--- [...] 1345 CLASS *array_type = (CLASS *)class->array_type; [...] --8<--- where array_type gets 0xc (GB_T_VARIANT or something like that) and is used as a pointer without further checking when overriding the Variant[] class (other native array classes may suffer from similar problems). I don't know how you made this working for me (just tried to get back to that revision to see, if something changed in that function but found nothing). Can you remember? - the subject of the mails was "Segfault when overriding Variant[]" (1st May 2012). Can you tell me something about the state of affairs?

Seems to be like the system headers here (Arch x86_64) typedef already (an anonymous struct).
