Text Functions

Quick thought. It might help..!!
load(
local!text: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
local!places: 1+enumerate(len(local!text)/4),
insert(
local!text,
"@",
4 * tointeger(local!places)
)
)

@rahulg262, cool. It works. Just replace "@" by char(10).
I am surprised that insert() works on text also. I thought it works on array only

The code above won't quite work - try running it with a text value of "123412341234123412" and you'll see the problems. Not only does it not insert at the correct locations, it also truncates the text if the length isn't divisible by the length that's required for the split.

This problem is a bit tricky due to the way insert works; it would seem that, for a split of length 4, that the correct insert locations would be {5, 10, 15, 20} but that's not actually the case - they should actually be {5, 9, 13, 17} as insert does all the inserts at once and doesn't re-evaluate the string each time an entry is inserted.

I've attached a modified piece of code that behaves as required. As @chetany has said, simply replace "@" at line 23 with char(10) to see the results as required.

Another option is this:

=with(
local!text: "fa fghagfhadkjlghadsjlgdhsjkglhdsjgklf",
joinarray(apply(mid(local!text, _, 4), 1+enumerate(len(local!text)/4)*4), char(10))
)

Yeah that's a lot simpler! Thinking about the original requirement, if the text is a paragraph of text, it would probably be better to do a fn!split() on spaces and then rejoin each set of 4 elements of that array with a char(10). Splitting a paragraph of text by a fixed number is going to look extremely odd as you're likely to be splitting mid-word in many cases.

yeah @philib instead of splitting with a constant number we can specify the space or some other parameter

Thank you for all your ideas.
I am splitting the text(ri!text) at each "x" number words(ri!wordIndex) using the expression rule in the txt file attached.
Any suggestions for improvement are welcomed.

Split Text By Word Index.txt

load(
local!len: len(
ri!word
),
local!index: enumerate(
local!len
) + 1,
local!indices: a!forEach(
items: local!index,
expression: {
if(
fv!item = 1,
0 + 1,
if(
len(
tostring(
fv!item / ri!count
)
) = 1,
fv!index + 1,
{}
)
)
}
),
local!result: joinarray(
a!forEach(
items: local!indices,
expression: mid(
ri!word,
fv!item,
ri!count
)
),
char(
10
)
),
local!result
)


ri!word = Your long text
ri!count = How many character you want to split them into

load(
local!text: "abcdefghijklmnopqrstuvwxyz",
local!places: 1+enumerate(len(local!text)/4),
insert(
local!text,
char(10),
4 * tointeger(local!places)
)
)
