can u support this feature?

Mon, 17 Nov 2008 02:37:30 -0700

as i have said on the last post,some package that i dont need,like when i wrote a console program,then i dont need gui package,else when i wrote a text processing program,then i dont need socket package ,etc
i see the current murgaLua interpreter can compile the script to an binari file,that's very powerful,then can u support an feature like this:
let people can diy which packages will in the interpreter,and then make a new interpreter,this feature will suit for many people i think

support for dd-wrt?

Sun, 09 Nov 2008 00:44:37 -0700

yes,dd-wrt
i think murgalua full version is so tiny and strongger than perl is
so i need to use it in dd-wrt
but the linux binari version occur error on dd-wrt

XPDF wrapper

Mon, 03 Nov 2008 11:34:04 -0700

I assume some people know xpdf, and have noticed that in almost no pdf viewer you can make bookmarks.
Now i've written a little thing to make bookmarks for a PDF file, viewed in xpdf (or as matter a fact, any pdfviewer that can work like a server thing).
OK, there are some rough edges, and functions on my wishlist, but it works for now...
Comments and suggestions welcome!

New stuff, 0.7.0 to be a public release

Thu, 30 Oct 2008 12:48:00 -0600

Hi,

I am sorry I have not posted anything recently.

Work and home pressures have had me off-line for a while and will probably still curtail my activities somewhat for a little while.

However ... I have had time to do some coding, and there is a full new public release on the way with some interesting features :-)

Comissioned items

OpenMoko port (not started, handset yet to arrive)
Encrypted database container support (Done)
Unicode support (50% done)

Other items

Fixes (mostly for minor Linux issues)
Some new API's (done)
Embeddable web-server and AJAX demo (80% done)
Unicode support (50% done)
BSD and SunOS ports (started)
Totally revised documentation and examples.

Date is pending ...

Some of these features may be released as a snapshot shortly.

Cheers
John de Murga

PDFTK frontend

Sun, 19 Oct 2008 05:32:16 -0600

Hi!

It's a bit quiet lately, so I thought i should break the silence :cool:.
Lately my dad had to extract some pages from a huge PDF file, and I wrote a little murga script that does that , using the amazing pdftk (http://accesspdf.com/pdftk/).
If you want to use it:
get pdfttk, (if you're on windows, it will work like that, linux/macos will need a tweak i guess). Then run the script, it will generate a config file (commands.txt). Edit it to be correct, and rerun the script... now that should work ;) For ease of distribution / foolproofing, one can use the murgaLua compiler.

Now i was thinking it would be great if we could write a more general (using more of the possibilities pdftk has), in a more guified (read average-daddy-proof) multiplatform frontend for it.
I already wrote another script to have murgalua write a shell script to have scans of even and odd pages (like the stuff you have when using a scanner with document feeder).

So if anyone wants to help, but i'm not (yet) enough experienced in the guistuff part...

Apologies ... Lack of time again ... Hoping it'll improve soon

Fri, 10 Oct 2008 02:15:25 -0600

Hi,

Events over the last few weeks have been a bit of drain on my time and my nerves ... I work for the financial world, so the reasons should be fairly obvious.

So I've been finding even less time to keep things moving, however, my plans are still in place and I have quite a lot of stuff for my next snapshot, I just don't have a clue when I'll get round to releasing it.

Cheers

Puppy Linux 4.08 x-server dies

Tue, 30 Sep 2008 04:53:47 -0600

Some time ago I wrote a little banking program using murgaLua and it works fine with Puppy Linux 3.01. It also seemed to work OK with version 4.0 and I think even up to version 4.06. It also works OK with Ubuntu 8.04.
However, since upgrading Puppy to version 4.08, inputting data (just typing into an input window) causes the x-server to die. Not necessarily after a return, but any character. It doesn't do this every time either but often enough to be really annoying.
I'm wondering if anyone else has noticed a problem of this sort?
Of course it may be my programing and changes to Puppy have just brought this to light or it could be that Puppy 4.08 is using the 2.6.25.16 kernel or some other change that Barry has made to Puppy.
I'm currently using murgaLua 0.6.8.

Perhaps I should ask on the Puppy Forum, but it's only when I'm using murgaLua that it occurs.

Any help would be appreciated.

UTF8 support and FL_Table.

Wed, 17 Sep 2008 05:45:17 -0600

Hi,

This is something that has been requested a few times.

And the last snapshot of FLTK 1.3 starts to support it in a way that is very friendly to murgaLua ... So I'll be trying to port the current code to it.

The other thing that is also always requested is Fl_Table ... I have a simple version that works (and FL_SimpleTable), however that code is a little more involved and I am still tidying up.

I am hoping to release a UTF8 build with a few more fixes this weekend.

It could include a preview of FL_Table and MurgaSrv ... But I doubt it.

Cheers
JohnM

PS : MurgaSrv ... You'll see :-)

Space Bar presses FLTK buttons

Tue, 16 Sep 2008 13:01:54 -0600

How to prevent this odd behavior?
There must be some setting I don't know about.

I have a button that opens a window, when I select a button on that window I thought closing the window would prevent its button from being hit twice, however the button on the first window gets hit and the window opens again.

Any ideas?

Fl_Table Not_Found in murgaLua 0.6.9, Why?

Tue, 16 Sep 2008 03:31:48 -0600

In my project, i always use grid to display data (data tabular view). I'm not satisfy with gridTest in examples code. So I search fltk documentation online, and i get Fl_Table to create nice grid. Why in murgaLua 0.6.9 Fl_Table is nothing to bind? :rolleyes:

the fltk loop and socket loop?

strange problem with fltk ,diffrent from cmdline start or drag/drop start

Mon, 15 Sep 2008 07:26:17 -0600

it is very stangely that i run the same code with diffrent start method
and one work well while the other do not
the code is

Code:
function quit_callback(msg)
   if fltk.fl_choice("Are you sure you want to EXIT ?", "No", "Yes", nil) >= 1 then
      w:hide()
      os.exit()
   end
end

ww,wh,wt=300,280,"Simple IRC Client - Powered by jyf1987"

w= fltk:Fl_Window(ww,wh,wt)
w:callback(quit_callback)

msgout= fltk:Fl_Browser(5, 5, 290, 240)

msgin= fltk:Fl_Input(5, 250, 290, 25)
msgin:callback(
function()
  msgout:add(msgin:value())
  msgout:bottomline(msgout:size())
  msgin:value("")
end
)
msgin:when(fltk.FL_WHEN_ENTER_KEY_ALWAYS)
w:show()

msgout:add("hello")
msgout:bottomline(msgout:size())

Fl:run()

when i run it from cmdline ,i juse type murgalua.exe 2chat.lua
it works well
but when i try to drag the code file 2chat.lua and drop it on murgalua.exe
it dont work

so what's the problem

i just want to test if the code ("msgout:add("hello")") run in the fltk loop

Snapshot build for 0.6.9 now available

Thu, 04 Sep 2008 21:08:31 -0600

Hi,

Can be found here :

http://www.murga-projects.com/murgaLua/snapshot.html

Please note that MINIMAL testing has taken place with this build.

This is a DEVELOPMENT snapshot of the current bloaty 0.6.X family.

Cheers
John de Murga

Hopefully a testing build tomorrow or the next day ...

Sun, 31 Aug 2008 12:21:15 -0600

I just need the weather to be a little worse and my better half to leave me alone a little :-)

All coding is done, and I am VERY happy with my FLTK tree control ...

Sorry for the delay

Cheers

MurgaLua 0.6.9 - Most of the coding is done - Features

Mon, 25 Aug 2008 07:28:11 -0600

Hi,

OK, I want to update the documentation over the next few days and make this a full blown release, as with my 0.7.X and Puppy work it may be a while until the next 0.6.X release ...

Also, this won't be the last 0.6.X release as 0.7.X will be much more experimental ...
And there are still a lot of performance tweaks I can back port into 0.6.X when I get the time (which right now is the main problem - time).

Currently this is the tested list of features :

Code:
Changes :

Misc fixes (core murgaLua and FLTK)
Compilation optimizations for all platforms.

Added support for trapping all non captured FLTK events :

    Fl.set_event_handler(callbackFunction)
    Fl:start_event_handler()
    Fl:stop_event_handler()

    This allows for better control of things like the DND events, etc.

The start of the "debug" API in murgaLua :

    murgaLua.debug.on()
    murgaLua.debug.off()
    murgaLua.debug.showTable(table)
    murgaLua.debug.printTable(table)
    (printTable replaces murgaLua.printDebug)

Tidied up tool/build structure a little.

Added Patrick Rapin's excellent new FLUID converter.

Build script now patches LUA and FLTK :

    LUA patch implements the "continue" statement.
    FLTK patch changes FLUID to allow for LUA callback code.

Upgrades

    sqLite engine upgraded to version 3.6.1 (performance and fixes)
    tinyxml engine upgraded to 2.5.3 (many fixes)
    copas upgraded to version 1.1.3 (adds better coroutine support)
    luafilesystem upgraded to version 1.4.1 (many fixes)
    luaSys upgraded to 1.3 (I think it's more stable now)
    md5 upgraded to 1.1.2 (very minor fixes)

Additions

    LuaDate  (2.0.1)   - All you need for complex date logic and handling
    cosmo    (8.04.14) - Templating library (for messages, web-pages, etc).
    lpeg     (0.8.1)   - Parsing Expression Grammar library (used by cosmo).
    coxpcall (1.13.0)  - Wraps pcall/xpcall for coroutines (used by copas).

And some examples to go with the new functionality.

Currently the executable is roughly about 20k larger than the previous build, and it is a little slower to initialize (not that you can notice it) ...
I am hoping to improve on that.

Cheers
John de Murga

sqlite database is locked

Sun, 24 Aug 2008 13:51:20 -0600

I've got programs that do simple inserts and updates on a single table. It all works fine if only one program is running at a time. I get the "database is locked" on the nrows iterator over a select statement if I start up a second program. I don't have any transactions, commits, rollbacks. Just working with one record at a time on a single table.

I've googled this, there is a lot written out there, but no clear simple solution that I could find.

Has anyone else encountered this? Is there a way to select a single row without using an iterator?

wxGlade for lua

Fri, 15 Aug 2008 17:01:45 -0600

There is an experimental version of the wxGLade GUI builder which will generate lua code. Of course, murgaLua doesn't include wxLua, but it can be added as a package.

I've experimented with it briefly and it has some nice features and a lot of potential.

If you support lua, you might want to check it out and send a note of encouragement to Makoto Hamanaka, who is the developer. His email is at the bottom of the page.

this is my test code to use fltk
the problem is when i add
fltk.fl_circle(110,100,50)

this will make a segmentation fault!
if remove this ,the script works well,so how to solve it?

ps:the problem both occur at win/lin
and other simple draw method will occur this too,

the code:[/code]

Code:
ww=220
wh=200
