I have an input string:
"aws_acm_certificate_validation"
What would be the best way to get a pair of strings separated on the first _ delimiter occurrence?
"aws" to "acm_certificate_validation"
.split() accepts a limit argument so that:
"aws_acm_certificate_validation".split("_", limit = 2)
will give you ["aws, "acm_certificate_validation"]

I am making a portfolio tracker in Google Sheets and wanted to know if there is a way to link the "TICKER" column with the code in the "PRICE" column that is used to pull JSON data from Coin Gecko. I was wondering if there was an f-string like there is in Python where you can insert a variable into the string itself. Ergo, every time the Ticker column is updated the coin id will be updated within the API request string. Essentially, string interpolation
For example:
TICKER PRICE
BTC =importJSON("https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids={BTC}","0.current_price")
You could use CONCATENATE for this:
https://support.google.com/docs/answer/3094123?hl=en
CONCATENATE function
Appends strings to one another.
Sample Usage
CONCATENATE("Welcome", " ", "to", " ", "Sheets!")
CONCATENATE(A1,A2,A3)
CONCATENATE(A2:B7)
Syntax
CONCATENATE(string1, [string2, ...])
string1 - The initial string.
string2 ... - [ OPTIONAL ] - Additional strings to append in sequence.
Notes
When a range with both width and height greater than 1 is specified, cell values are appended across rows rather than down columns. That is, CONCATENATE(A2:B7) is equivalent to CONCATENATE(A2,B2,A3,B3, ... , A7,B7).

SPLIT: Divides text around a specified character or string, and puts each fragment into a separate cell in the row.
JOIN: Concatenates the elements of one or more one-dimensional arrays using a specified delimiter.
my #r = split("", "hi");
say #r.elems;
--> output: 4
split is adding two extra elements to the array, one at the beginning and another at the end.
I have to do shift and pop after every split to correct for this.
Is there a better way to split a string?
If you're splitting on the empty string, you will get an empty element at the start and the end of the returned list as there is also an empty string before and after the string.
What you want is .comb without parameters, written out completely functionally:
"hi".comb.elems.say; # 2
See https://docs.raku.org/routine/comb#(Str)_routine_comb for more info.
The reason for this is when you use an empty Str “” for the delimiter it is the same as if you had used the regex /<|wb>/ which matches next to characters. So it also matches before the first character, and after the last character. Perl 5 removes these “extra” strings for you in this case (and in this case only), which is likely where the confusion lays.
What Perl 6 does instead is allow you to explicitly :skip-empty values
'hi'.split('') :skip-empty
'hi'.split('', :skip-empty)
split("", "hi") :skip-empty
split("", "hi", :skip-empty)
Or to specify what you actually want
'hi'.comb( /./ )
'hi'.comb( 1 )
'hi'.comb
comb( /./, 'hi' )
comb( 1, 'hi' )
I need to count how often a number is present in a string. it should count EVERY occurence with a whitespace in front, except those followed by a =.
For example:
If i need to know how many "1" there are in this string: this is a 1 ramdnom string with 2 numbers 1 with 1=something it should return 2, as the third one is followed by an =
To find the occurrences I am using this: occurences = mystring.Split(" 1").Length - 1
But how to exclude those followed by a =?
Thanks
Something like,
Dim occurrences = Regex.Matches(yourString, "\W[0-9]([^=]|$)").Count
If you'd like to do replacements, use a Regex.Replace overload.
Breaking it down, this expression matches
\W // any whitespace character
[0-9] // any deciaml digit
( // either
[^=] // not =
| // or
$ // the end of the string
)
Hello all I had a text file in which it contains thousands of lines/records and they are in the following format
6242S10TH AVENUE KWANOBUHLE Y 6242
the space between these words are also inconsistent.so, now I just want to split this data into three separate columns so as to make a table.
If you assume this:
There is at least three spaces between colums
A column value doesn't contain as much as three spaces
There are no empty column values
You can split a line on three spaces and trim the values. C# example:
string[] columns =
line.Split(new string[]{" "}, StringSplitOptions.None)
.Select(s => s.Trim())
.ToArray();

I've found two parameters defined like these:
&TM_PERIOD+4&/&TM_PERIOD(4)&
It's to pass data from a database to a form.
If the format of the data would be DDMMYYYY what are differences between those two parameters?
if TM_PRIOD is in form of DDMMYYYY then
TM_PERIOD(4) equals DDMM
TM_PERIOD+4 equals YYYY
the (4) means 4 characters
the +4 means after the 4th character
TM_PERIOD+1(2) = DM
(2 characters after the first)
These are not bit operations. +n specifies a string offset and (n) specifies the length.
They can be used independently of each other as well, so you can use just +n or just (n).
So:
data: lv_text(20) type c.
lv_text = "Hello".
write: / lv_text+2(3).
would output 'llo', for example.
