Re: regex backreferences

[J. Landman Gay via use-livecode]

I wish it did, but replaceText doesn't support back references. The 
parameters at the end are treated as literals, whether as actual quoted 
literals or variables containing a value.


If there isn't a feature request for it, there should be.

Hi all,

Does the replaceText() function allow the use of backreferences to retain

I want to end up something like this:

In BBedit I can search for (.*) and 
replace it with \1 and it preserves the run of text designated by 
parentheses.
(I know, I can get more fancy on matching the runs of html tags, but I’m 
mainly interested in retaining the text, not in regex madness.)


In LC this does not work:

  put replaceText(myText,"  style=“cruft”>(.*)”,”\1”) into myText


I just end up with \1, when I want Good stuff here.

Can replaceText even do this?

Re: [ANN] Release 10.0.0 DP-1

[matthias rebbe via use-livecode]

Mark,

i've just filed bug #23485
https://quality.livecode.com/show_bug.cgi?id=23485 


I noticed that as soon as the keyword URL is in a script, even if the line is a 
comment, the remote access, for example to set the filename of an image to a 
remote url as Kevin showed in the Webcamp presentation, does not work anymore.

Regards,

Matthias

Double check if this is not CORS related. It is very easy to have a request

Re: How to extract whole text from a PDF file with the PDF

[Paul McClernan via use-livecode]

Ah, OK thanks for the clarification. I hadn’t realize PDFium has been
around as long as it has been.
I wouldn’t sweat the naming conflict, there’s at least three “PDFKit”
libraries so you’re not alone.

Nope. My company (Researchware) and I paid for the development of the 
XPDF External shipped with LiveCode. Monte did the code for us when he 
was an independent LiveCode developer, paid directly by Researchware. It 
is based on the C++ "external" API template, calling the Google PDFium 
library. Researchware then transferred the license to LiveCode when 
Monte went to work for them. I called it XPDF because it was an eXternal 
for PDFs. I was unaware (at the time) for anything else using the XPDF

for messages, commands, and functions of the XPDF external (with Monte 
correcting me when I had a really stupid syntax specified)




The newer (> 9.6.3) PDF Widget is based on PDFium which is an offshoot
project that spawned from Google’s Chromium project. I’m not sure about the
licensing involved with that.

If you’re running macOS I released a (semi-complete) library that uses
Apple PDFKit (not to be confused with several other PDFKits that are out
there, such as this JS PDFKit: https://pdfkit.org ). That can extract text
from PDF, per-document or per-page.

At some point I may update that library, adding the ability to extract RTF
styled text and also make iso it can use UIView, which would make available
on iOS devices too, but I’m really busy right now so that’s not likely to
get attention from me anytime soon.

Note my "if".

In the next message in this thread Paul clarified that the component is
not derived from a GPL-governed work, so the rights and responsibilities
of the GPL do not apply here:

Re: How to extract whole text from a PDF file with the PDF

[Paul McClernan via use-livecode]

I was fairly certain that XPDF external was/is based on this XPDF:
https://en.m.wikipedia.org/wiki/Xpdf
Which has both GPL and Proprietary Licensing options available.

The newer (> 9.6.3) PDF Widget is based on PDFium which is an offshoot
project that spawned from Google’s Chromium project. I’m not sure about the
licensing involved with that.

If you’re running macOS I released a (semi-complete) library that uses
Apple PDFKit (not to be confused with several other PDFKits that are out
there, such as this JS PDFKit: https://pdfkit.org ). That can extract text
from PDF, per-document or per-page.

At some point I may update that library, adding the ability to extract RTF
styled text and also make iso it can use UIView, which would make available
on iOS devices too, but I’m really busy right now so that’s not likely to
get attention from me anytime soon.

Re: IOS 15.0

[Mark Smith via use-livecode]

Correct, in this case I think it’s complaining I don’t have the correct SDK in 
the build. The LC docs (including release notes for 9.6.5) only go up to 14.5 
so rather than experiment I was hoping someone already had a tried and true 
formula for working with 15.0. I'm afraid this is entirely my own fault. It’s a 
newish iPhone and I forgot to turn off auto-update.

I think you'll need to include an Edit menu with the normal shortcuts 
(Cut/Copy/Paste) - make sure the tag of the items is correct as the 
engine uses those to map them to the internal (Cocoa) references. e.g.


  (Cu /X|cut
  ( /C|copy
  ( /V|paste

Cocoa-based controls (which the browser widget uses the WebView variant 
of) don't respond to shortcuts directly, but only via menu item 
accelerators - so the browser widget needs the menu items present for 
such shortcuts to work.


Warmest Regards,

Mark.

How to paste into a form element in the browser widget

[Tore Nilsen via use-livecode]

I have a problem pasting into a form element on a web page in the browser 
widget. This works well in the IDE, but not in a standalone application. The 
application has no menus, but I have included a pasteKey script to handle paste 
shortcuts. This does not seem to do the trick in the browser widget. I have 
tried to put the script in the stack script, the card script and even in the 
widget itself, although I wouldn’t expect the latter to work. Are there anyone 
who has run across this problem before and may offer a solution?
