ตรวจสอบพยัญชนะต้น (ต้องมี) ตรวจตัวสะกดสำหรับสระที่ต้องมี ตรวจสอบการวางสระและวรรณยุกต์ไทย หมายเหตุ การตรวจสอบตัวสะกดในภาษาไทยตรวจสอบได้ยากเพราะภาษาไทยเป็นภาษาที่เขียนติด ๆ กันไม่มีการแบ่งคำอย่างชัดเจนทำให้การอ่านภาษาไทยผู้อ่านต้องใช้ความหมายของคำในการตัดสินการอ่านแบ่งคำตามความเหมาะสมเช่นคำว่า "ตากลม" อาจอ่านเป็น "ตาก-ลม" ก็ได้ หรืออ่านเป็น "ตา-กลม"ก็ได้ ดังนั้นการเขียน Regex เพื่อทำการตรวจสอบอาจช่วยได้ระดับหนึ่ง อ่าจมีผิดบ้างถูกบ้าง แต่ก็ถือว่าเป็นเครื่องมือที่ใช้ช่วยเหลือในการตรวจสอบเพิ่มเติมได้ 80% ของความเป็นไปใด้ก็แล้วกันนะครับ หวังว่าการเขียนเพิ่มเติมส่วนนี้ จะมีประโยชน์บ้างไม่มากก็น้อย

Regex for Matching Documentation Websites This repository contains a powerful regular expression designed to match URLs that commonly point to documentation-related websites. The regex is optimized for flexibility, covering various terms and URL patterns. Regex Pattern ^.(?:\.|\/)(docs|documentation|help|guide|manual|reference|api|kb|support|resources|wiki|developer|how-to|tutorials|examples|learn|instructions)(?:\.|\/)?.$ Purpose This regex is intended to identify URLs that contain keywords associated with documentation or support websites. It handles common patterns in subdomains, directories, and file paths. Explanation ^.*: Matches any characters at the beginning of the URL (any prefix). (?:\.|\/): Matches either a period (.) or a forward slash (/) preceding the keyword. (docs|documentation|help|guide|manual|...): Matches any of the keywords listed in the group. (?:\.|\/)?: Allows an optional period (.) or forward slash (/) following the keyword. .*$: Matches any characters following the keyword (any suffix). Examples Positive Examples The following URLs should match the regex: https://example.com/docs http://docs.example.com https://example.com/documentation https://sub.domain.com/docs/index.html https://example.com/help https://api.example.com/docs http://example.com/manual/index.html https://wiki.example.com http://developer.example.com/guide https://example.com/tutorials/docs/page https://kb.example.com/docs/tutorial.html https://example.com/resources/documentation/tutorial.html http://example.com/reference/help/documentation.html https://developer.example.com/docs/tutorials/index.html http://support.example.com/documentation/overview https://resources.example.com/docs/v1/tutorial https://example.com/how-to/documentation http://example.com/api/reference/docs https://example.com/reference/v2/index.html http://example.com/docs/resources/api.html Negative Examples The following URLs should not match the regex: https://example.com/documentary http://helpful.example.com https://manuals.example.com http://example.com/references https://example.com/resourceful http://example.com/wiki-books https://apiary.example.com http://example.com/documents http://example.com/documentable https://help-center.example.com http://manual.example.com/docsystem https://example.com/resourcesful http://api.example.comary https://example.net/instructions-v1 http://example.org/learned-tutorial http://example.com/support-center Author Jeremy Georges-Filteau Website Github
