Works as expected/coded. Not sure how it would be changed (don’t know how to get to that state inside the widget). Anyway, to work with this you need to have your handler check to see if it needs to run. Pretty easy if using it to navigate between cards. If already on the destination card, then exit the handler. Another way is to set a flag to skip the change handler before manually making the change in code. Then when the handler starts, check for the flag before continuing.

Re: Implementing UNDO
LC’s built in undo does not appear to undo anything done by something I have
scripted.
My approach is to use a global array variable “u” to store information needed
to undo the most recent action. On each action, an “undoInit” puts empty into
u, after (if necessary) cleaning up anything u’s values indicate is left over
from the prior action (e.g., actually deleting an object that had been only
“pseudo-deleted” (hidden) so as to make the user’s choice of deletion
undoable). Then the appropriate new values are loaded into u. The main
elements I use are
# u["cardID"] = short id of the card where the undoable action was taken
# u["stackName"] = short name of the stack where the undoable action was taken
# u["changed"], list of objects being changed, each line has: propName,objectID
# u[propName,objectID] holds prior value of that property of that object (one
key/value for each line of u["changed"]
# u["removed"], list of objectID,cardID,stackName for objects being
pseudo-removed
# u["added"], list of objectID,cardID,stackName for objects being added
# u["cardsRemoved"], list of cards being pseudo-removed, each line has:
cardID,cardNumber
# u["cardsAdded"], list of cards being added, each line has: cardID,cardNumber
The “Undo” command makes sure we’re on card id u[“cardID”] of stack
u[“stackName”}, then checks for non-empty values of
u[“changed”],u[“removed”],u[“added”],u{“cardsRemoved”], and u[“cardsAdded”],
and uses values stored in u to restore the prior state of things, while
reloading u with values reporting the state of things now being reversed.
For text, I load u[“changed”] with “htmlText”,, and load
u[“htmlText”,] with the htmlText of that field before the latest
editing.

lock messages and navigation bar widget
Hi friends, am I missing something? This does not work with my navigation bar widget at least not as exspected: on mouseUp lock messages set the hiliteditemname of widget 1 to "contacts" unlock messages end mouseUp - Icon does change, but the widgets "hilitechanged" handler is fired!? So no change of icon possible without firing the "hilitechanged" message? Thanks for any hint!

Re: Implementing UNDO
As other have said, the basic mechanism is to have a UNDO LIFO (last in first out) queue or stack (no LC stack for a data structure stack). For each action you want 'undoable" you need a handler (do[action] ) to perform that action that also adds a record (a line) to the queue (a property, global variable, or script variable) that puts enough information in that record to undo the action. You then you have a corresponding undo[action] handler that can take the record from the queue and reverse the action. So records on the queue might look like: changeFont -- which can be undone by setting the to resizeImage etc. The first item tells you action was done and the subsequent items provide enough information to undo (or do again or redo) the action.

Re: Spurious characters from html files - text encoding issues?
BBEdit has a built in "guess encoding" function to try to determine the encoding of a text file. I have had this bug in to LC now for 6 years: https://quality.livecode.com/show_bug.cgi?id=14474 Even Frasier, who did much of the Unicode work for LC7 agreed there should be a guessEncoding function in Livecode. Instead, anyone who needs one either has to write their own or find someone who has written one to get one from. While you can never tell with 100% accurate the encoding for all text files, there are algorithms that make pretty good guesses. I'd still like to see it as a build in function in the LC engine. On 5/21/2021 8:19 AM, Keith Clarke via use-livecode wrote: Hi Ben, Thanks for the further details and tips - my problem is now solved! The BBedit tip re file 'open-as UTF-8' was a great help. I’d not noticed these options before (as I tend to open files from PathFinder folder lists not via apps). However, this did indeed reveal format errors on these cache files when they were saved with the raw (UTF-8 confirmed) htmltext of widget “browser”. Text encoding to UTF-8 before saving fixed this issue and re-crawling the source pages has resulted in files that BBEdit recognises as ‘regular’ UTF-8. This reduced the anomaly count but whilst testing, I also noticed that the read-write cycle updating the output csv file was spawning anomalies and expanding those already present. So I wrapped this function to also force UTF-8 decoding/encoding - and now all is now good. No longer will I assume that a simple text file is a simple text file! :-) Thanks & regards, Keith On 19 May 2021, at 19:01, Ben Rubinstein via use-livecode wrote: Hi Keith, This might need input from the mothership, but I think if you've obtained the text from the browser widget's htmlText, it will probably be in the special 'internal' format. I'm not entirely sure what happens when you save that as text - I suspect it depends on the platform. So for clarity (if you have the opportunity to re-save this material; and if it won't confuse things because existing files are in one format, and new ones another) it would probably be best to textEncode it into UTF-8, then save it as binfile. That way the files on disk should be UTF-8, which is something like a standard. What I tend to do in this situation where I have text files and I'm not sure what the format is (and I spend quite a lot of time messing with text files from various sources, some unknown and many not under my control) is use a good text editor - I use BBedit on Mac, not sure what suitable alternatives would be on Windows or Linux - to investigate the file. BBEdit makes a guess when it opens the file, but allows you to try re-opening in different encodings, and then warns you if there are byte sequences that don't make sense with that encoding. So by doing this I can often figure out what the encoding of the file is - once you've got that, you're off to the races. But if you have the opportunity to re-collect the whole set, then I *think* the above formula of textEncoding from LC's internal format to UTF-8, then saving as binary file; and reversing the process when you load them back in to process; and then doing the same again - possibly to a different format - when you output the CSV, should see you clear.

It never occurred to me that these html files might be anything other than simple plain text files, as I’d work with in Coda, etc., for years. The local HTML files are storage of the HTML text pulled from the LiveCode browser widget, saved using the URL ‘file:’ option. I’d been working ‘live’ from the Browser widget’s html text until recently, when I’ve introduced these local files to split page ‘crawling’ and analysis activities without needing a database. Reading the files back into LiveCode with the URL ‘file:’ option works quite happily with no text anomalies when put into a field to read. The problem seems to arise when I load the HTML text into a variable and then start to extract elements using LiveCode's text chunking. For example pulling the text between the offsets of say & tags is when these character anomalies have started to pop into the strings. A quick test on reading in the local HTML files with the URL ‘binfile:’ option and then textDecode(tString, “UTF-8”) seems to reduce the frequency and size of anomalies, but some remain. So, I’ll see if re-crawling pages and saving the HTML text from the browser widget as binfiles reduces this further.

Re: Implementing UNDO
For text, the method will depend on the size of the text. In general, implement an undo stack and a redo stack. For single line fields it could simply be a list for each. After each change, add entry to undo list and clear redo list. When doing undo, move entries to redo list allowing forward/backward movement between changes. For longer text, an array based stack could be used. Either store the full text or use the diff library - method will depend on size of text.

Re: Spurious characters from html files - text encoding issues?
Hi Ben, Thanks for the further details and tips - my problem is now solved! The BBedit tip re file 'open-as UTF-8' was a great help. I’d not noticed these options before (as I tend to open files from PathFinder folder lists not via apps). However, this did indeed reveal format errors on these cache files when they were saved with the raw (UTF-8 confirmed) htmltext of widget “browser”. Text encoding to UTF-8 before saving fixed this issue and re-crawling the source pages has resulted in files that BBEdit recognises as ‘regular’ UTF-8. This reduced the anomaly count but whilst testing, I also noticed that the read-write cycle updating the output csv file was spawning anomalies and expanding those already present. So I wrapped this function to also force UTF-8 decoding/encoding - and now all is now good. No longer will I assume that a simple text file is a simple text file! :-) Thanks & regards, Keith > On 19 May 2021, at 19:01, Ben Rubinstein via use-livecode > wrote: > > Hi Keith, > > This might need input from the mothership, but I think if you've obtained the > text from the browser widget's htmlText, it will probably be in the special > 'internal' format.

Re: iOS screen size
Hello Dan, Rough guess, are you including a custom plist? If so, then this plist was probably created by an older LC version, before storyboard support was added. If this is the case, the (old) plist expects some splash images, which are not in the app bundle, thus you see the black bars.

Hi Dan, did you try fullscreen set to “ShowAll”? Also,I set the background color of my splash to a color that matched the background of my splash screen image so now it “appears” to cover the full screen of all device sizes.
