ANSI SGR Process

Extract ANSI SGR Sequences from string

[!NOTE] Tab\t will be replaced by 4 spaces

Usage

• Extract(string) -> (*ANSITableList, string)
  split string with ansi into ansi sequences and raw string
• Render(atl *ANSITableList, _s string, startIndex int) -> []byte
  Render string with ansi sequences, startIndex is the start index of _s which will be used to fetch ansi table
• Search(bs []BoundStruct, position int) -> (res []int)
  binary search index given Bound [2]int, the result is index.
  len(res) <= 2 and -1 means reach the start/end of the slice
  len(res) == 1 means the position is within bs[res[0]].Bounds
len(res) == 2 means the position is between bs[res[0]].Bounds[1] and bs[res[1]].Bounds[0]
• *ANSITableList SetStyle(style []byte, startIndex, endIndex int)
  set style for string[startIndex:endIndex]
