identcasing

Small Nim library for converting between common identifier casing styles.

Supported styles:

• upperSnakeCase
• lowerSnakeCase
• titleSnakeCase
• lowerKebabCase
• upperKebabCase
• trainCase
• headerCase as an alias for trainCase
• dotCase
• lowerCamelCase
• pascalCase

Example

import identcasing

echo convertCase("user_profile_id", lowerSnakeCase, lowerCamelCase)
# userProfileId

echo convertCase("HTTP_SERVER_PORT", upperSnakeCase, lowerKebabCase)
# http-server-port

let words = parseWords("oauth2ClientId", lowerCamelCase)
echo words
# @["oauth2", "client", "id"]

echo renderWords(words, titleSnakeCase)
# Oauth2_Client_Id

echo lowerKebabCaseToLowerCamelCase("questionnaire-response-id")
# questionnaireResponseId

Notes

• The library parses identifiers into lowercase words and renders those words into a target style.
• Camel parsing keeps digits attached to the preceding word, so identifiers like oauth2Client, utf8String, and ipv6Address stay intact.
• Because of that rule, some values do not round-trip through camel case. For example, PBM-123 becomes pbm123, and converting that back to upperKebabCase yields PBM123.
