trim() in dzVents ? [Solved]

[willemd]

Does dzvents have a trim() function? I cannot find it in the documentation.

I am importing data and one of the fields has a trailing space that I want to remove.
I tried the stringSplit function with space as separator but this did not achieve the result.
Currently I am forcing conversion to a number and then converting back to a string to achieve this.

Does a trim() function exist?

Don't know if dzvents has this function but in case not:

Code: Select all

-- Trim a string
stringTrim = function(s)
  return s:match'^%s*(.*%S)' or ''
end

Dzvents has no trim function, neither does Lua but there are lots of ways to create one: http://lua-users.org/wiki/StringTrim

Thank you both, one solution is enough

What kind of programming language is used for that function definition? I don't recognise it and can't decifer the logic. It works but I don't see why.

[Doler]

It's Lua. There is a little error in the function (sorry for that): 'match' should be 'string.match'. I guess you can recognize it now.

Assembler, basic, algol, pascal, lisp, cobol, various 4gl's, python, dzVents, probably forgetting a few .... I am trying not to add Lua to it.

Thank you for your solution.
