This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Public Function

extension

Public Function
std.fs.path.extension
pub fn extension(path: []const u8) []const u8

Searches for a file extension separated by a . and returns the string after that .. Files that end or start with . and have no other . in their name are considered to have no extension, in which case this returns "". Examples:

  • "main.zig" ⇒ ".zig"
  • "src/main.zig" ⇒ ".zig"
  • ".gitignore" ⇒ ""
  • ".image.png" ⇒ ".png"
  • "keep." ⇒ "."
  • "src.keep.me" ⇒ ".me"
  • "/src/keep.me" ⇒ ".me"
  • "/src/keep.me/" ⇒ ".me" The returned slice is guaranteed to have its pointer within the start and end pointer address range of path, even if it is length zero.

Params

  • path: []const u8
