Scriban template split string

Question

I have a pipe-separated string

www.test.com | www.test1.com

I want to get just the first string before the pipe that is www.test.com.

How can I do this in the scriban template?

Answer 1

Scriban has a split function on strings: https://github.com/scriban/scriban/blob/master/doc/builtins.md#stringsplit

string.split <text> <match>

The split function takes on a substring as a parameter. The substring is used as a delimiter to divide a string into an array. You can output different parts of an array using array functions.

Also check the whitespace control if needed (I do see spaces around your pipes): https://github.com/scriban/scriban/blob/master/doc/language.md#14-whitespace-control

• The greedy mode using the character - (e.g {{- or -}}), removes any whitespace, including newlines
• The non greedy mode using the character ~
  • Using a {{~ will remove any whitespace before but will stop on the first newline without including it
  • Using a ~}} will remove any whitespace after including the first newline but will stop after

Working with arrays is explained at https://github.com/scriban/scriban/blob/master/doc/builtins.md#array-functions. You could use array.first <list> to get the first element.

Update

Try: {{ i_item.URLList | string.split "|" | array.first }}

That should do it..

Answer 2

Maybe you can use the string split (by '|') function that will get you the array: [www.test.com, www.test1.com]. Then you can read first element of the array using array first function. Example:

{{ for word in "Hi, how are you today?" | string.split ' ' ~}}
{{ word }}
{{ end ~}}

output

Hi,

how

are

you

today?
