Conditional description

First sorry if it is not the correct place for the post...
So I want to make simple check if index_title is longer than 50 characters and if it is to move the content of index_title from the first occurance of "-" to the end to index_description. For example:
index_title is: bla bla bla 123 - blablablabla bla blablablabla blablablabla blabla blablabla blablablabla blablablabla blabla blablabla blablablabla blablablabla
I want the result to be:
index_title: bla bla bla 123
index_description: blablablabla bla blablablabla blablablabla blabla blablabla blablablabla blablablabla blabla blablabla blablablabla blablablabla
Thank you!

Hi Martos,
 
I give you three possible solutions.
 
For all three you will need to prepare the condition of the > 50 characters in title and further save the unchanged title in a temp element:
 
index_temp_1.modify {clear} * make sure is empty
index_temp_1.modify {addstart|'index_title'} *copy title
index_temp_6.modify {calculate(type=char format=F0)|'index_temp_1' #} *number of chars
 
The first solution , with regex , is the most compact but needs some understanding of regular expressions:
 
index_title.modify {substring(debug 'index_temp_6' > "50" type=regex)|'index_temp_1' "(\A.*)-"} *change title under condition > 50 chars
index_description.modify {substring(debug 'index_temp_6' > "50" type=regex)|'index_temp_1' "-(.*$)"} *move part of title to desc under condition
 
*The second solution works with element split by means of the standard element split character |
 
index_temp_1.modify {replace(debug 'index_temp_6' > "50")|-|\|} * split copied title in parts at -
index_temp_2.modify {substring(debug type=element)|'index_temp_1' 0 1} *first part
index_title.modify {replace(debug 'index_temp_6' > "50")|'index_title'|'index_temp_2'} *replace title by its first part
index_temp_2.modify {substring(debug type=element)|'index_temp_1' 1 1} *second part}
index_description.modify {addend('index_temp_6' > "50")|'index_temp_2'}
 
The third works with indices (places)

index_temp_2.modify {calculate(type=char format=F0)|'index_temp_1' "-" @} * index_of (place) of the - character
index_title.modify {substring(debug 'index_temp_6' > "50" type=char)|0 'index_temp_2'} * the first part 0=start 'index_temp_2' = length
index_temp_2.modify {calculate(format=F0)|1 +} * add 1 to get past the - char
index_temp_3.modify {substring(debug 'index_temp_6' > "50" type=char)|'index_temp_1' 'index_temp_2'} * the second part upto the end 'index_temp_1' = source element, 'index_temp_2'= start , length not required = default to end
index_description.modify {addend('index_temp_6' > "50")|'index_temp_3'}

Hi WGMaker,
Thank you very much for your answer! It is written to be understood perfectly even by people who are not familiar with the syntax.
Keep up the good work! :)
