Functions ¶
func AsString ¶
func AsString(x interface{}) string
AsString returns the argument in a 'string' form no matter what type it is.
func AutoIndexColumnID ¶
AutoIndexColumnID returns a unique Column ID/Name for the given Column Index. The functionality is similar to what you get in an Excel spreadsheet w.r.t. the Column ID/Name.
func FilterStrings ¶
FilterStrings filters the slice 's' to items which return truth when passed to 'f'.
func GetLongestLineLength ¶
GetLongestLineLength returns the length of the longest "line" within the argument string. For ex.:
GetLongestLineLength("Ghost!\nCome back here!\nRight now!") == 15
func InsertRuneEveryN ¶
InsertRuneEveryN inserts the rune every N characters in the string. For ex.:
InsertRuneEveryN("Ghost", '-', 1) == "G-h-o-s-t"
InsertRuneEveryN("Ghost", '-', 2) == "Gh-os-t"
InsertRuneEveryN("Ghost", '-', 3) == "Gho-st"
InsertRuneEveryN("Ghost", '-', 4) == "Ghos-t"
InsertRuneEveryN("Ghost", '-', 5) == "Ghost"
func IsNumber ¶
func IsNumber(x interface{}) bool
IsNumber returns true if the argument is a numeric type; false otherwise.
func IsString ¶
func IsString(x interface{}) bool
IsString returns true if the argument is a string; false otherwise.
func RuneCountWithoutEscapeSeq ¶
RuneCountWithoutEscapeSeq is similar to utf8.RuneCountInString, except for the fact that it ignores escape sequences in the counting. For ex.:
RuneCountWithoutEscapeSeq("") == 0
RuneCountWithoutEscapeSeq("Ghost") == 5
RuneCountWithoutEscapeSeq("\x1b[33mGhost\x1b[0m") == 5
RuneCountWithoutEscapeSeq("\x1b[33mGhost\x1b[0") == 5
func TrimTextWithoutEscapeSeq ¶
TrimTextWithoutEscapeSeq trims a string to the given length accounting for escape sequences For ex.:
TrimTextWithoutEscapeSeq("Ghost", 3) == "Gho"
TrimTextWithoutEscapeSeq("Ghost", 6) == "Ghost"
TrimTextWithoutEscapeSeq("\x1b[33mGhost\x1b[0m", 3) == "\x1b[33mGho\x1b[0m"
TrimTextWithoutEscapeSeq("\x1b[33mGhost\x1b[0m", 6) == "\x1b[33mGhost\x1b[0m"
func WrapText ¶
WrapText wraps a string to the given length using a newline. For ex.:
WrapText("Ghost", 1) == "G\nh\no\ns\nt"
WrapText("Ghost", 2) == "Gh\nos\nt"
WrapText("Ghost", 3) == "Gho\nst"
WrapText("Ghost", 4) == "Ghos\nt"
WrapText("Ghost", 5) == "Ghost"
WrapText("Ghost", 6) == "Ghost"
WrapText("Jon\nSnow", 2) == "Jo\nn\nSn\now"
WrapText("Jon\nSnow\n", 2) == "Jo\nn\nSn\now\n"
