utils#
import "github.com/magnus-ffcg/go-dbt2lookml/pkg/utils"Package utils provides utility functions for string manipulation and pointer helpers.
This package contains reusable utility functions used throughout the application for common operations like string transformation, sanitization, and pointer creation.
String Utilities:
- CamelToSnake: Converts CamelCase to snake_case (handles acronyms correctly)
- SnakeToCamel: Converts snake_case to CamelCase
- ToLookMLName: Converts column names to LookML-compatible identifiers
- SanitizeIdentifier: Removes invalid characters from identifiers
- QuoteColumnNameIfNeeded: Adds backticks for names requiring quoting
Pointer Helpers:
- StringPtr, BoolPtr, IntPtr, Int64Ptr, Float64Ptr: Create pointers to literal values
String Manipulation:
- TruncateString: Safely truncate strings to maximum length
- Pluralize: Simple English pluralization
- ToTitleCase: Convert to title case
The package uses pre-compiled regular expressions for optimal performance in frequently-called string transformation functions.

func BoolPtr#
func BoolPtr(b bool) *boolBoolPtr returns a pointer to the given bool value. This is a convenience function to avoid creating intermediate variables.
func CamelToSnake#
func CamelToSnake(s string) stringCamelToSnake converts CamelCase to snake_case Handles complex cases like SupplierInformation -> supplier_information, GTINId -> gtin_id
func ContainsAny#
func ContainsAny(s string, substrings []string) boolContainsAny checks if a string contains any of the given substrings
func Float64Ptr#
func Float64Ptr(f float64) *float64Float64Ptr returns a pointer to the given float64 value. This is a convenience function to avoid creating intermediate variables.
func Int64Ptr#
func Int64Ptr(i int64) *int64Int64Ptr returns a pointer to the given int64 value. This is a convenience function to avoid creating intermediate variables.
func IntPtr#
func IntPtr(i int) *intIntPtr returns a pointer to the given int value. This is a convenience function to avoid creating intermediate variables.
func IsEmpty#
func IsEmpty(s string) boolIsEmpty checks if a string is empty or contains only whitespace
func JoinNonEmpty#
func JoinNonEmpty(parts []string, delimiter string) stringJoinNonEmpty joins non-empty strings with a delimiter
func Pluralize#
func Pluralize(word string) stringPluralize adds ’s’ to a word (simple pluralization)
func QuoteColumnNameIfNeeded#
func QuoteColumnNameIfNeeded(columnName string) stringQuoteColumnNameIfNeeded adds backticks around column names that need quoting
func RemovePrefix#
func RemovePrefix(s, prefix string) stringRemovePrefix removes a prefix from a string if it exists
func RemoveSuffix#
func RemoveSuffix(s, suffix string) stringRemoveSuffix removes a suffix from a string if it exists
func SanitizeIdentifier#
func SanitizeIdentifier(s string) stringSanitizeIdentifier removes or replaces invalid characters from identifiers
func SnakeToCamel#
func SnakeToCamel(s string) stringSnakeToCamel converts snake_case to CamelCase
func SplitAndTrim#
func SplitAndTrim(s, delimiter string) []stringSplitAndTrim splits a string by delimiter and trims whitespace from each part
func StringPtr#
func StringPtr(s string) *stringStringPtr returns a pointer to the given string value. This is a convenience function to avoid creating intermediate variables.
func ToLookMLName#
func ToLookMLName(s string) stringToLookMLName converts a column name to LookML naming convention. Converts PascalCase to snake_case and replaces dots with double underscores.
Note: This function expects proper PascalCase or camelCase input. If your column names are already lowercase (e.g., “supplierinformation”), they will remain as-is since there’s no case information to work with. Ensure your source data maintains proper case conventions (e.g., “SupplierInformation”) for correct conversion.
func ToTitleCase#
func ToTitleCase(s string) stringToTitleCase converts a string to Title Case
func TruncateString#
func TruncateString(s string, maxLength int) stringTruncateString truncates a string to a maximum length
