feat: enable config for obsidian-md-plugins rules only

[chrisgrieser]

If you use a linter other than eslint (in my case biome), you may want to only enable Obsidian-specific rules, without all the other eslint rules resulting in duplicate warnings, the need to configure eslint for your specific setup, etc.

currently, there is no direct export of the obsidian-plugin-only rules, so I added that, along with a documentation how to configure eslint for that.

Some external rules should still be enabled by default or have documented replacements in the other linter.

• no-eval
• no-implied-eval
• no-console
• no-restricted-globals
• no-restricted-imports
• the two rules imported from @microsoft/sdl
• import/no-nodejs-modules

I don't know about enabled by default, because that would exactly result in the problem of duplicate diagnostics with the other linters.

Maintaining a list of equivalent rules with other linters is going to be tedious, since there are numerous linters which might also change rule structure over time.

I think the best solution would be to just document the list of non-obsidian-but-still-recommended rules in the Readme?

I looked into this. Most of these rules have a Biome equivalent, but not all. import/no-nodejs-modules could probably be covered by adding Node builtins to restricted imports, but no-implied-eval and @microsoft/sdl/no-document-write seem to require additional effort.

ESLint rule	Biome equivalent	Notes & config snippet
no-eval	noGlobalEval	Biome rule: "noGlobalEval" rejects use of eval(). (Biome) Example config: json { "linter": { "rules": { "correctness": { "noGlobalEval": "error" } } } }
no-implied-eval	No exact direct equivalent found	ESLint’s no-implied-eval forbids e.g. setTimeout("…", 1000). Biome doesn’t list a dedicated rule by that name. You could potentially use noGlobalEval to cover eval() calls, but implied-eval via strings may not be covered yet.
no-console	noConsole	Biome lists noConsole as the equivalent for ESLint’s no-console. (Biome) Example: json { "linter": { "rules": { "correctness": { "noConsole": "error" } } } }
no-restricted-globals	noRestrictedGlobals	Biome maps ESLint’s no-restricted-globals to noRestrictedGlobals. (Biome) Example: json { "linter": { "rules": { "correctness": { "noRestrictedGlobals": { "level": "error", "options": ["event", "fdescribe"] } } } } }
no-restricted-imports	noRestrictedImports	Biome has noRestrictedImports which maps to ESLint’s rule. (Biome) Note: According to discussions, the patterns / paths options may be partially supported. (GitHub) Example: json { "linter": { "rules": { "correctness": { "noRestrictedImports": { "level":"error", "options": { "paths": { "old-module": { "message":"Use new-module instead" } } } } } } } }
@microsoft/sdl/no-document-write	No built-in equivalent found	This is a plugin rule (from eslint-plugin-microsoft-sdl) forbidding document.write. Biome doesn’t list a built-in rule covering document.write. You may need to implement a custom rule or disable this check.
@microsoft/sdl/no-inner-html	lint/security/noDangerouslySetInnerHtml (React) or no exact generic built-in	For React, Biome has noDangerouslySetInnerHtml under the lint/security domain, forbidding use of dangerouslySetInnerHTML. (Biome) But for generic innerHTML assignments in non-React contexts there may not be a built-in equivalent yet — you may need custom linting or plugin.
import/no-nodejs-modules	No exact built-in equivalent found	ESLint plugin rule forbids importing certain Node.js built-in modules (or disallowed modules). Biome doesn’t list a direct mapping for “no importing nodejs built-in modules” rule. You might approximate via noRestrictedImports, listing the built-ins as restricted.
