how to add strings to a string

[tranquil obsidian]

I have this line of code
grids := make([]*gim.Grid, len(images))
That adds images from a set of variables. But to make it work the way i need to I can't have the entire images path in images which would normally be images/01.png, images/01.png, images/01.png but I need to have an easier input for users so I have had to change images to 01 01 01

For this to work I need to change the grids bit into
grids := make([]*gim.Grid, "images/" + len(images) + ".png") but I get this error when trying so.

Any help in how to correctly add "images/" and ".png" would help a lot 🙂

The second argument of make is the length of the array

"images/1.png" is not exactly a length

You perhaps trying to do make([]*gim.Grid, len(images))?

ohh I see that makes more sense sorry, I had someone else help work on that bit and they fell asleep before I could ask them to explain what it all means

I'll work through the code more and find where I'm meant to do what I'm trying to do aha

With strings.Split(s, " ") how could I also add text to the start and end of each split

It is unclear what you are asking

[tranquil obsidian]

I'm trying to split "I1 I1 I1" into "images/I1.png", "images/I1.png", "images/I1.png"

Solved

func doTheThing(s string) []string {
 r := strings.Split(s)
 for i, v := range r {
  r[i] = filepath.Join("images", v + ".png")
 }
 return r
}

I'll keep this in mind for the future but was able to do it with just {imageFilePath: "images/" + path + ".png"}

that might be an issue on windows just so you know

the point of filepath.Join is that it join correctly based on the OS

where windows uses \
