PasteCheck v1.7 + v1.8 — Hints that tell you what to fix, and a nudge panel that tells you where to start PasteCheck v1.7 introduces actionable, one-sentence fix suggestions for every error and warning message across JavaScript, TypeScript, Python, HTML, and CSS, replacing vague alerts with clear instructions like "use 'const' if the value never changes." Version 1.8 adds a collapsible "What to do next" panel that provides high-level debugging guidance, designed to help beginners understand and resolve issues rather than just identify them. Both updates were inspired by user feedback that knowing what is wrong is insufficient without knowing what to do next. Most linters tell you what's wrong. They stop there. PasteCheck has always shown you the error and the line. But "var is discouraged" doesn't tell a beginner what to actually do about it. "Empty catch block" doesn't tell you why it matters or what to replace it with. That changes in v1.7. Every error and warning message now ends with one actionable sentence. Not a docs link. Not a vague suggestion. One clear fix. Prefer 'let' or 'const' over 'var' — use 'const' if the value never changes, 'let' if it does 'eval ' executes arbitrary code — dangerous and a security risk — remove it and find a safer alternative like JSON.parse or a lookup object Empty catch block — errors are silently swallowed — add at least console.error e so failures don't disappear silently This covers every language PasteCheck supports — JavaScript, TypeScript, Python, HTML, and CSS. 30 messages updated across the entire linter. Two Reddit commenters validated this independently before it was built. Both said the same thing unprompted — knowing what's wrong isn't enough, you need to know what to do next. That's what v1.7 ships. v1.8 adds something no other paste tool has. When errors or warnings exist, a collapsible "What to do next" panel appears below the results. Not per-error guidance — big picture debugging logic. The kind of thing an experienced developer would tell you if they were sitting next to you. It's collapsed by default. It doesn't get in the way. It's there when you need it. Both features were designed around the same principle — PasteCheck doesn't just find your mistakes, it helps you understand them. Built entirely from an Android phone.
