HTML entities

Many years ago, I wrote a HyperText function to convert accented and other special characters to HTML entities.

I was recently looking at the now LiveCode stack that contains this function, in order to modify the old textual entities into numeric ones. The function is:

Code: Select all

function textToEntities textToCheck
   
   put "&,ä,á,à,â,ã,å,æ,ë,è,é,ê,í,ï,î,ñ,ö,ó,ò,ô,õ,ü,ú,ù,ç,Å,Æ,Ö,Ü,…,—,£,¡,ß" into textTable
   put "&,ä,á,à,â,ã,å,æ,ë,è,é,ê,í,ï,î,ñ,ö,ó,ò,ô,õ,ü,ú,ù,ç,Å,Æ,Ö,Ü,…,—,£,¡,ß" into entityTable
   put 0 into itemCount
   
   repeat for each item textTableItem in textTable
      get textTableItem
      add 1 to itemCount
      replace it with item itemCount of entityTable in textToCheck
   end repeat 
   
   return textToCheck
end textToEntities
Is there a more "automatic" way (perhaps a built-in function) to do this in LiveCode?

Hola Exheusden,

if you can live with html entity NAMES instead of numbers, you can use something like this, from a quick test:

Code: Select all

on mouseUp
   put "&,ä,á,à,â,ã,å,æ,ë,è,é,ê,í,ï,î,ñ,ö,ó,ò,ô,õ,ü,ú,ù,ç,Å,Æ,Ö,Ü,…,—,£,¡,ß" into TT
   set the text of the templatefield to TT
   put the HTMLtext of the templatefield into fld 1
   reset the templatefield
end mouseUp
You get the picture. :D

Best

Klaus

Thank you again, Klaus. That looks a lot tidier!

However, this returns the old character HTML entities, such as &,ä,á,à,â,ã,å,æ,ë,è, etc.

I want the entity numbers, such as &,ä,á,à,â,ã,å,æ,ë,è, etc

Yep, that's why I wrote:

Indeed, and I can't, so should I take it that there is no more efficient way to achieve what I want than my code? It works surprisingly well, but seems a bit dated (just like my car…).

For LC 7/8/9 an (Unicode-) extended table may be interesting?

For example the currency symbol for Euro is in the lookup table below:

Code: Select all

€€
So this works in LC 7/8/9:

Code: Select all

set htmltext of fld "OUT1" to "€"
For generating your conversion list you could use
      codepointToNum and numToCodepoint
for example, with the Euro symbol,
      codepointToNum("€") and numToCodepoint(8364)

Here is my lookup table sorted by the (decimal) numbers:

Code: Select all

""
