[ANN] iOS document interaction external added to mergExt

[Monte Goulding]

Hi LiveCoders

mergExt (http://mergext.com) has grown again with a new external called 
mergDoc. The suite now includes 8 externals: barcode reading, video recording, 
extended file attributes, iAd banners and more.

mergDoc is an iOS external that adds functions and commands related to document 
interaction. This currently includes presenting a modal preview, open in app 
menu, document options menu and requesting the document icons in PNG form. 
Printing is also available via the preview. mergDoc with 29% of the vote came 
in a close second in the poll to MapKit. There's a new poll up now but clearly 
MapKit is next on the hit list.

Users can now also participate in the mergExt affiliate program to get a free 
month of updates for every sale. Once logged in you will see the referral url 
above the poll.

Don't forget to vote for what you want next! If you want something that's not 
on the poll then add it to the Ideas topic in the mergExt forum.

That would only work if the lines you wanted to filter out only contained a tab 
character. If they contain other stuff then you need one of the following...

filter tvar without ("*"&tab&"*") -- if the tab can be anywhere in the line
filter tvar without (tab&"*") -- if the tab is at the start of the line, or
filter tvar without ("*"&tab) -- if the tab is at the end of the line

Re: Sqlite and performances in LiveCode

[Pete]

Hi Trevor,
OK, found the problem.  I had a set dgProps["sort by column"] statement
after setting the dgNUmberOfRecords.  Moved that to a place where
dgNumberOfRecords is zero and only one cycle of GetDataForLine happens now.

Thanks for the help in tracking it down.  There are a lot of nuances to
using dgNumberOfRecords!

Re: Passing parameters by reference

Hi, Bob!

This concern is understandable.  However, I think we can distinguish between an 
expression that means a value and an expression that means a mutable place.  We 
have this distinction in LiveCode.

The expression '4 + a' can be used only as a value.  The expression a[3] can be 
used as a value or a mutable place.  That value is what is contained in that 
mutable place.  That mutable place is called a container in HyperCard.

We can't say 'put 7 into 4+a' but we can say 'put 7 into a[3]'.

The concept has strong HyperCard and LiveCode precedence.  We can say 'put 3 
into char 2 of item 6 of a'.  A "chunk" is a container.

Allowing @ parameters to refer to containers and not just variables can create 
some implementation challenges, perhaps, even some documentation challenges, 
but it does open the door to commands that can be used to, say, capitalize the 
value of containers.  I would hope the conceptual challenges in use would only 
apply to advanced users doing weird things.  

In the simplest case, the extension would replace "variable" with "container" 
in the description of @.  

I come from a background in functional programming in which just about 
everything is a value and not a container, but I have embraced the language 
used in LiveCode and the ability to modify things in ways besides replacing 
variable values and replacing properties.

Re: Cyberduck versus Flow

[Bill Vlahos]

Mark,

I've used Cyberduck for years and have really liked it…until recently. The 
newer versions sometimes messes up my files when I upload them to the web site. 
Most files work fine but some don't that used to. I've reported it to the 
vendor who cannot reproduce the problem.

I've been using Fetch instead which works fine although I prefer Cyberduck.

Re: Cyberduck versus Flow

I use Cyberduck and Taco HTML Edit together to get the benefits of the
combined editor/ftp.  Cyberduck detetcs the presence of Taco on your
computer and includes a contextual menu item to download a file into Taco,
then when you save it in Taco it automatically upload to the server again.

Re: Cyberduck versus Flow

[Scott Rossi]

Hi Francis:

If you want cheap, Flow is on sale at the moment, so it is a great deal.
I've used it a bit, though not with On_Rev, and it has worked fine.

If you're looking specifically for a Mac solution -- there are other FTP
tools that have been around for a while but cost more:
Fetch - http://fetchsoftworks.com/fetch/
Transmit - http://www.panic.com/transmit/

One thing you might want to consider is a combination code-editor/FTP app
like Panic's Coda or MacRabbit's Espresso.  You edit your code locally and
then upload from the same interface.  Espresso has an option that can
automatically upload your page every time you save locally, which is a great
timesaver in some situations.  I have been using Espresso for a while now,
and while it sometimes need to be "refreshed" with On-Rev, I love it.

Re: Cyberduck versus Flow

[Richmond]

Personally I've been using Cyberduck for about 5 years, and
don't understand the comments about its clumsy interface;
all seems remarkably straightforward to me.

Experience with almost all other FTP clients seems to fall
short of Cyberduck.

But, Hey, I'm talking about sending stuff from my PPC macMini running 10.4,
so don't take my word as far as the "latest thang" goes.

Cyberduck versus Flow

[Francis Nugent Dixon]

Hi from Beautiful Brittany,

Maybe a little outside LiveCode discussions, but
I want the best app to upload my files to my On-Rev
server.

I was happy with FileZilla, then I found Cyberduck which
really makes me happy, now I see "Flow" which seems to
beat all the FTP apps hands down (cheap at $4.99).

Can I get some feedback from Cyberduck/Flow users to
help me decide whether to go with the flow (pun intended !)

Re: options for safe transfer of data to a server - ?

[Pierre Sahores]

Hi,

The sole solution i know is to own a dedicated server and to access it in SSH 
tunneling (SFTP) mode with only some open ports 22, 25, 80, 443, etc... you can 
tune as you want as long as you take care to keep the unwanted ports closed 
(alike FTP = 21).

There are probably ways to tune SFTP to let multiple users use it on a shared 
server but i did't try to setup this kind of config for yet.

Kind regards,

Re: options for safe transfer of data to a server - ?

[Alex Tweedly]

ftp is indeed a security problem, and sftp is not (easily) available - 
needs externals, or command line usage, etc.


https:// would be an option - but he would need an ssl cert.

However, if the item to be uploaded is small (sounds like it is), then 
you can do it very safely and easily, just as a get URL with the 
parameters encrypted from within LC.


LC on the client machine (pseudo code):
   put "My machine has been installed" && tMyName && tMyOtherData into 
tDataToSendToServer

   encrypt tDataToSendToServer with des using password "mysecretpassword"
   put it into tData
   put "http://my.domain.com/registerinstall.lc?data="; & 
urlencode(tData) into tURL

   get URL (tURL)

(and of course, make sure that you keep the password safe, only do this 
within a protected stack, etc.



and on the server, you simply take the data passed, urldecode it, 
decrypt it (with the same secretpasword) and log it to the file.



There is a tiny insecurity here - someone could flood you with bad URL 
gets and grow you logfile out of control - which can easily be avoided 
by passing a security check, e.g. ( add this code immediately before the 
get URL above)


   put the seconds into tTime
   encrypt tTime with des using password "mysecretpassword"
   put it into tEncTime
   put "?time=" & tTime & "&enctime=" & tEncTime after tURL

and then on the server, verify that the enctime value can be decrypted 
to get the time value; only save the data if that matches OK.

Re: Exporting a snapshot directly to Preview

[Colin Holgate]

My variation of the syntax leaves it up to the system to open the file. It 
would be wrong of you to predetermine that a user sees the document in any 
particular program. Just leave off the part where you set the app to use, and 
the system will take care of that for you.

If you have the dgNumberOfRecords set to a positive number then that makes
sense as the data grid has to redraw.

If the dgNumberOfRecords is set to 0 (and messages aren't locked when
setting it) then I'm not sure why that is. Setting the dgNumberOfRecords to
0 should do the trick as it empties out the internal sDataArray array.
GetDataForLine is only sent if an entry in the sDataArray array is NULL.

Re: options for safe transfer of data to a server - ?

[stephen barncard]

simple ftp has no security for world accessible web sites. I just had all
my sites compromised by Pakistani hackers, and will be spending much of the
next two days cleaning up. I have since repented and am using SFTP with
Dreamhost.

But that doesn't help those that want to use Livecode FTP.

There are external solutions that are used by Andre and Trevor, but are a
bit more complicated and I haven't tried them.

One of those many feature requests pending.

Re: Exporting a snapshot directly to Preview

Thanks Scott and Colin,

LiveCode and this list make it sooo easy. It is almost embarrassing.

Does anyone know what program, if there is ONE, that opens when you double 
click on a jpg or png image in Windows?

What happens when you click on an image.jpg? Does Windows present options?

How do I run a shell command from inside LiveCode on a Mac?

The full solution I want to do is to run the "id" command as administrator so I could run 
"sudo id" but I want to prompt for a successful authentication.

I know how to do this in AppleScript so I could just call that but I would 
rather to it in LC.

Bill Vlahos



shell() is a function not a command. From the looks of it, you seem to 
have left off the 'get' or 'put' command to execute the function.

Oh that is an interesting thought. But still, if the presentation is very 
complex just the writing of a stack that would respond to the Applescript 
commands would be a lot of work.

Re: Slightly OT - LC in Keynote

[Mike Bonner]

Don't know how it would be accomplished, but apparently "send to program"
lets you do some interesting things, and since its based on
appletalk/applescript type of events, it might be possible to talk to a
separate running stack that way?

Obviously neither powerpoint nor keynote have the same verbiage, so they
can't "send to program" but they can "tell application" through
scripting so it might be worth a shot.  Wish I still had a mac so I could
try all these neat things.
