with Iris\n\n\n\nFeatures\n--------\n\nAll features of Sundown are supported, including:\n\n* **Compatibility**. The Markdown v1.0.3 test suite passes with\n the --tidy option. Without --tidy, the differences are\n mostly in whitespace and entity escaping, where blackfriday is\n more consistent and cleaner.\n\n* **Common extensions**, including table support, fenced code\n blocks, autolinks, strikethroughs, non-strict emphasis, etc.\n\n* **Safety**. Blackfriday is paranoid when parsing, making it safe\n to feed untrusted user input without fear of bad things\n happening. The test suite stress tests this and there are no\n known inputs that make it crash. If you find one, please let me\n know and send me the input that does it.\n\n NOTE: \"safety\" in this context means *runtime safety only*. In order to\n protect yourself against JavaScript injection in untrusted content, see\n [this example](https:\/\/github.com\/russross\/blackfriday#sanitize-untrusted-content).\n\n* **Fast processing**. It is fast enough to render on-demand in\n most web applications without having to cache the output.\n\n* **Thread safety**. You can run multiple parsers in different\n goroutines without ill effect. There is no dependence on global\n shared state.\n\n* **Minimal dependencies**. Blackfriday only depends on standard\n library packages in Go. The source code is pretty\n self-contained, so it is easy to add to any project, including\n Google App Engine projects.\n\n* **Standards compliant**.

The Markdown v1.0.3 test suite passes with\n the --tidy option. Without --tidy, the differences are\n mostly in whitespace and entity escaping, where blackfriday is\n more consistent and cleaner.\n\n* **Common extensions**, including table support, fenced code\n blocks, autolinks, strikethroughs, non-strict emphasis, etc.\n\n* **Safety**. Blackfriday is paranoid when parsing, making it safe\n to feed untrusted user input without fear of bad things\n happening. The test suite stress tests this and there are no\n known inputs that make it crash. If you find one, please let me\n know and send me the input that does it.\n\n NOTE: \"safety\" in this context means *runtime safety only*. In order to\n protect yourself against JavaScript injection in untrusted content, see\n [this example](https:\/\/github.com\/russross\/blackfriday#sanitize-untrusted-content).\n\n* **Fast processing**. It is fast enough to render on-demand in\n most web applications without having to cache the output.\n\n* **Thread safety**. You can run multiple parsers in different\n goroutines without ill effect. There is no dependence on global\n shared state.\n\n* **Minimal dependencies**. Blackfriday only depends on standard\n library packages in Go. The source code is pretty\n self-contained, so it is easy to add to any project, including\n Google App Engine projects.\n\n* **Standards compliant**.
