func (StrOps) FindRegExIndex ¶

func (sops StrOps) FindRegExIndex(targetStr string, regex string) []int

FindRegExIndex - returns a two-element slice of integers defining the location of the leftmost match in targetStr of the regular expression (regex).

Return Value ============ The return value is an array of integers. If no match is found the return value is 'nil'. If regular expression is successfully matched, the match will be located at targetStr[loc[0]:loc[1]]. Again, a return value of 'nil' signals that no match was found.

func (StrOps) GetSoftwareVersion ¶

func (sops StrOps) GetSoftwareVersion() string

GetSoftwareVersion - Returns the software version for StrOps.

func (StrOps) ReplaceMultipleStrs ¶

func (sops StrOps) ReplaceMultipleStrs(targetStr string, replaceMap [][][]string) string

ReplaceMultipleStrs - Replaces all instances of string replaceMap[i][0][0] with replacement string replaceMap[i][0][1] in 'targetStr'

func (StrOps) StrCenterInStr ¶

func (sops StrOps) StrCenterInStr(strToCenter string, fieldLen int) (string, error)

StrCenterInStr - returns a string which includes a left pad blank string plus the original string, plus a right pad blank string.

The complete string will effectively center the original string is a field of specified length.

func (StrOps) StrCenterInStrLeft ¶

func (sops StrOps) StrCenterInStrLeft(strToCenter string, fieldLen int) (string, error)

StrCenterInStrLeft - returns a string which includes a left pad blank string plus the original string. It does NOT include the Right pad blank string.

Nevertheless, the complete string will effectively center the original string is a field of specified length.

func (StrOps) StrGetCharCnt ¶

func (sops StrOps) StrGetCharCnt(targetStr string) int

StrGetCharCnt - Uses the 'len' method to return the number of characters in a string.

func (StrOps) StrGetRuneCnt ¶

func (sops StrOps) StrGetRuneCnt(targetStr string) int

StrGetRuneCnt - Uses utf8 Rune Count function to return the number of characters in a string.

func (StrOps) StrLeftJustify ¶

func (sops StrOps) StrLeftJustify(strToJustify string, fieldLen int) (string, error)

StrLeftJustify - Creates a new string with a total length equal to input parameter 'fieldLen'.

Input parameter 'strToJustify' is placed on the left side of the output string and spaces are padded to the right in order to create a string with total length of 'fieldLen'.

Example:

fieldLen        = 15
strToJustify    = "Hello World"
Returned String = "Hello World    "
String Index    =  012345648901234

func (StrOps) StrPadLeftToCenter ¶

func (sops StrOps) StrPadLeftToCenter(strToCenter string, fieldLen int) (string, error)

StrPadLeftToCenter - Returns a blank string which allows centering of the target string in a fixed length field.

func (StrOps) StrRightJustify ¶

func (sops StrOps) StrRightJustify(strToJustify string, fieldLen int) (string, error)

StrRightJustify - Returns a string where input parameter 'strToJustify' is right justified. The length of the returned string is determined by input parameter 'fieldlen'.

func (StrOps) SwapRune ¶

func (sops StrOps) SwapRune(currentStr string, oldRune rune, newRune rune) (string, error)

SwapRune - Swaps all instances of 'oldRune' character with 'newRune' character.

func (StrOps) TrimEndMultiple ¶

func (sops StrOps) TrimEndMultiple(targetStr string, trimChar rune) (rStr string, err error)

TrimMultipleChars - Performs the following operations on strings:

1. Trims Right and Left for all instances of 'trimChar'
2. Within the interior of a string, multiple instances of 'trimChar' are reduce to a single instance.

Example:

targetStr = " Hello World " trimChar = ' ' (One Space) returned string (rStr) = "Hello World"
