# coldfusion-cfc A Copilot rule that sets coding standards for ColdFusion components: CFScript, cfqueryparam, clean getters and setters. Useful when your repo has .cfc files. - rule · `type=rule` · GitHub Copilot · ★ 40418 - Author: github · official GitHub repository - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/github/awesome-copilot/tree/HEAD/instructions/coldfusion-cfc.instructions.md - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/rules/coldfusion-cfc ## What it does The rule attaches to files matching `**/*.cfc` and tells the agent how to write components. Core asks: prefer CFScript over tags, skip deprecated tags and functions, keep naming consistent for variables and components. For SQL injection protection, use `cfqueryparam`. Inside `` blocks, escape CSS hash symbols with `##`. Then come component-level practices. Properties and methods live in the `this` scope, functions get access modifiers (`public`, `private`, `package`, `remote`), and components collaborate through dependency injection. Getters and setters stay simple, with no business logic inside. Input parameters in public and remote methods get validated and sanitized, and errors are handled with `cftry`/`cfcatch`. Configuration and credentials stay out of CFCs. Indentation is 2 spaces, ternary operators are welcome, and related methods sit together. Every function is documented with its purpose, parameters and return value. The file goes to `.github/instructions/coldfusion-cfc.instructions.md` — without it the rule never loads. ## Install ### GitHub Copilot (native platform) **Manually: put the files in place** - File: `.github/instructions/coldfusion-cfc.instructions.md` — The applyTo field sets which files it applies to ### Claude Code **Manually: put the files in place** - File: `.claude/rules/coldfusion-cfc.md` — The paths frontmatter field limits the files: move applyTo from the source into paths ### Codex **AGENTS.md** - Codex reads AGENTS.md: paste the rule text there ### Cursor **Manually: put the files in place** - File: `.cursor/rules/coldfusion-cfc.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/rules/coldfusion-cfc.md` ### Cline **Manually: put the files in place** - File: `.clinerules/coldfusion-cfc.md` Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/coldfusion-cfc.instructions.md ## When to use it - bring `.cfc` components to one coding style - close SQL injection holes with `cfqueryparam` - strip deprecated tags and functions from the codebase - document functions with parameters and return values - move configuration and credentials out of components ## Example prompts - write a new CFC for order handling following the project standards - check this `.cfc` for deprecated tags and add `cfqueryparam` to the queries - refactor the getters and setters and drop the business logic from them ## Source text · coldfusion-cfc.instructions.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 34baa4482eabe413 ```text --- description: 'ColdFusion Coding Standards for CFC component and application patterns' applyTo: "**/*.cfc" --- # ColdFusion Coding Standards for CFC Files - Use CFScript where possible for cleaner syntax. - Avoid using deprecated tags and functions. - Follow consistent naming conventions for variables and components. - Use `cfqueryparam` to prevent SQL injection. - Escape CSS hash symbols inside blocks using ## # Additional Best Practices - Use `this` scope for component properties and methods when appropriate. - Document all functions with purpose, parameters, and return values (use Javadoc or similar style). - Use access modifiers (`public`, `private`, `package`, `remote`) for functions and variables. - Prefer dependency injection for component collaboration. - Avoid business logic in setters/getters; keep them simple. - Validate and sanitize all input parameters in public/remote methods. - Use `cftry`/`cfcatch` for error handling within methods as needed. - Avoid hardcoding configuration or credentials in CFCs. - Use consistent indentation (2 spaces, as per global standards). - Group related methods logically within the component. - Use meaningful, descriptive names for methods and properties. - Avoid using `cfcomponent` attributes that are deprecated or unnecessary. - Use ternary operators where possible - Ensure consistent tab alignment. ``` END THIRD-PARTY FILE 34baa4482eabe413 The third-party file has ended.
