This regular expression is designed to validate Egyptian mobile phone numbers by ensuring they conform to the following format: Country Code: The number must start with +20, representing Egypt's international dialing code. Mobile Networks: (Vodafone: 10, e&:11, Orange:12, we:15) Operator Code: The phone number must be followed by one of the valid operator prefixes (10, 11, 12, or 15), corresponding to major mobile networks in Egypt. Number Length: The phone number must have exactly 8 digits following the operator code, for a total of 11 digits (including the country code and operator code). This regex is commonly used to ensure that the input phone numbers follow the standard Egyptian format and belong to the correct mobile operators.

Strip all HTML tags from a string. HTML tags are enclosed in . The regex will be applied on a line-by-line basis, meaning partial tags will need to be handled by the regex. Don't worry about opening or closing tags; we just want to get rid of them all. Note: This task is meant to be a learning exercise, and not necessarily the best way to parse HTML

It needs a major modification, since matching an integer is required. The accepted answer \d+ involves only "positive" integers. But -333 or +777 are also integers, which leads to two possible solutions with the last one being the most accurate: -?\d+ : The hyphen (optional minus sign) and a digit 1 or more times. To include the negatives. [+-]?\d+ : Optional + or - and the quantity of more than 0 digits.`

This is a GitHub Advanced Security (GHAS) Secret Scanning Custom Pattern I created to detect likely hardcoded credentials while reducing common false positives in code. Goal: detect assignments for these key names: password secret apikey / api_key / api-key Pattern regex: (?i)\b(password|secret|api[-]?key)\b\s[:=]\s(?!\s\$\{)(?!\sprocess\.env\b)(?:['"])?[A-Za-z0-9!@#$%^&()+=-]{5,}(?:['"])? What it should catch (examples): password: "ahsjdfahsjfhdjsahj" secret = 'kjfskahfsdhfj' apikey: ABCDE12345!@# (unquoted) What it tries NOT to catch (common false positives): password: ${password_somename} (template/variable placeholder) secret: ${VAULT_SECRET} password: process.env.DB_PASSWORD (env var reference, not a hardcoded secret) This is intended as a practical baseline; it won’t be perfect for every language/config style. If you have suggestions to improve the detection accuracy (reduce false positives/false negatives) for GHAS custom patterns, please share.

Regex Pattern ^\s+|\s+$|(\s)\s+ Replacement $1 Description This regex pattern performs multi-purpose whitespace normalization by: Removing leading whitespace (^\s+) Trimming trailing whitespace (\s+$) Collapsing multiple consecutive whitespace characters into a single space ((\s)\s+ → \1) The replacement \1 preserves the first captured whitespace character while eliminating redundant ones, ensuring clean, standardized spacing.

You can express the required dice-throwing as usual: 1d10, 2d6, 3d8... The first part (dice number) is mandatory. So, notations like "D10" are not computed, and they must be written as 1d10 The dice number may be expressed as [number]o[number]. For example: 1o3d10. That will mark to implement a Gauss system, throwing 3 dice but only giving the value of the middle one. If that's the case, it is possible to add a symbol + or - at the end of the dice number value, to mark if whether you want the lowest or the highest value instead. The second part of the dice (the number of sides) may be any integer You can add a ! or a ¡ (or both) at the end of the notated dice to represent exploding and imploding dices In addition, you can express a modifier in the form of a subtraction (-3, for example) or an addition (+2, for example) You can finally add a threshold (:20, for example).
