matches anime filenames. such as Group] Name [Episode[Audiometa]others.ext supports NCOP, NCED, OP, ED, SP, SPnn, nn, nn.n, nn.n_vn mp4, mkv, srt, ass but you could add more. the episode must be written within a [] bracket. finally, this regex cannot cover all the cases and obviously have some issues, but it's fine under most cases. it is also a small regex practice for me.

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.

This regular expression provides a balance between RFC compliance and security-best-practices. It is designed to prevent injection vectors in legacy systems by using a restricted "safe" character subset recommended by the OWASP Validation Regex Repository. Pattern: ^A-Za-z0-9(?:\.A-Za-z0-9_+&-]+)*@(?:[A-Za-z0-9{0,61}[A-Za-z0-9])?\.)+[A-Za-z]{2,63}$ Key Features: Forced Alphanumeric Start: Prevents leading hyphens to avoid command injection vulnerabilities. Security Subset: Restricts special characters to _+&*- to prevent exotic character injections (e.g., pipes or backticks). No Quoted Strings: Forbids quoted strings to eliminate dangerous payloads containing spaces or backslashes. DNS Compliance: Enforces label lengths (1–63 characters) and prevents labels from starting or ending with hyphens. Whole String Anchoring: Uses ^ and $ to ensure the entire input is validated.

Overview This Regular Expression shows any text between HTML tags or between quotation marks within the tags themselves. An example would be: <HTML lang="en", then selecting the 'en' from there. Group 1 is between tags, and group 2 is in the quotes. I recommend only using half of this regular expression, like the 'between tags' part, or the 'inside quotes part'. Explanation The whole regex is built of two alternates, the tags and quotes part. The tags part (the first part) starts with a lookbehind of a closing of a tag, then a lazy part that selects almost characters, and a lookahead that checks for the beginning of tag (so the text is between tags). The quotes part is built in a similar structure, where it looks behind for an open of a tag, .+ , then checking for an equals sign followed by a quotation mark. The middle section of the quotes part is again just searching for text, but also not including quotation marks. The lookahead checks for a closing quotation mark and that's it! Please comment any questions or email me.

'Alle anzeigen' : 'Nur Zauberer anzeigen'} {visibleCharacters.map(function(character) { return {character.name}; })} ); } // in App.jsx export default function App() { return ; }
