itemoffset & wholematches
Hi list,
I have a variable with a content of 3 lines as follows :
1 sombre brunprofond
2 flouincertain
3 inexploré mystérieux inconnu
The separator between words is tab.
I want to check if a certain word is among the items as a whole.
The following script returns "6" :
set itemdel to tab
set the wholematches to false
put itemoffset("incertain",myVar)
The following script returns "0" :
set itemdel to tab
set the wholematches to true
put itemoffset("incertain",myVar)
The following script returns "7" :
set itemdel to tab
set the wholematches to true
replace return with tab in myVar
put itemoffset("incertain",myVar)
Scripts 1 & 3 are logical, but any logical explanation
for the result of script 2 ? Does it mean that the return
char after the word is considered as part of the word ?
Thanks in advance.
jbv

Re: itemoffset & wholematches
the easy way to fix this problem: replace cr with tab in myVar -- but if the line endings matter, this isn't great On Mon, Nov 14, 2022 at 9:00 AM Mike Kerner wrote: > you set the itemDelimiter to tab. the is part of the item. > -- On the first day, God created the heavens and the Earth On the second day, God created the oceans.

Re: itemoffset & wholematches
Why not just use is among the items?

Re: itemoffset & wholematches
that still won't work if the text is the last item of a line.
in the example, below, i've taken his original, replaced the tabs with
commas, and for the purpose of being able to read what's going on,
substituted the cr for a backslash, and added a line to substitute it back
for the test.
*put*
"1,sombre,burn,profound\2,flou,incertain\3,inexploré,mystériux,inconnu" into
myVar
*replace* "\" with cr in myVar
*put* "profound" is among the items of myVar

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
and did a little diving.
And God said, "This is good."

Re: itemoffset & wholematches
oic. Odd use case. I suppose a lineOffset function followed by is among the items could be used. If he needs the lines to remain intact he could also replace cr with tab & cr first.

Re: itemoffset & wholematches
That would deal with the last item in a line - but not the first. Should do replace CR with TAB & CR & TAB in ... and reverse later if needed. Alex.

Re: itemoffset & wholematches
How about a one-liner:
put wordOffset("incertain",myVar)
If the words ever have punctuation attached, use trueWordOffset.

Re: itemoffset & wholematches
Hi guys, Thank you all for your answers. Actually I thought that some "hierarchy"remained (items inside lines) when using itemoffset, but obviously I was wrong. I have about 6 variables to check, so I need my script to be as fast as possible. I use "replace CR with TAB & CR & TAB in ...", but as I need to get the exact itemoffset digit, I also need to count how many items I have added and substract that number from the result, which is quite cumbersome and slow... To Jacqueline : Thanks fro the suggestion, but I have to stick with items and itemoffset, for some items can contain more that 1 word, like "pied de biche"...

Re: itemoffset & wholematches
Hi,
I don't know if this will be faster, slower, or what !?! Something like
put myVar into tCopy
replace CR with TAB in tCopy
put itemoffset("incertain", tCopy) into tmp
put the number of chars in item 1 to (tmp-1) of tCopy into tCharCount
put the number of items in char 1 to tCharCount of myVar into
theRealAnswer
Or, depending on what you do next, just go on using charOffset rather
than itemOffset for the following code.

Re: itemoffset & wholematches
If the data always contains the same number of items, I again highly recommend
pushing everything to a memory based sqLite file then doing queries on it.

Re: itemoffset & wholematches
Again guys, thank you for your suggestions. But finally I gave up using itemoffset and worked with arrays instead, which is much much faster : my script processes the 6 variables in less than 15 secs. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
