os.FileExists

The os.FileExists function attempts to resolve the path relative to the root of your project directory. If a matching file or directory is not found, it will attempt to resolve the path relative to the contentDir. A leading path separator (/) is optional.

With this directory structure:

content/
├── about.md
├── contact.md
└── news/
    ├── article-1.md
    └── article-2.md

The function returns these values:

{{ fileExists "content" }} → true
{{ fileExists "content/news" }} → true
{{ fileExists "content/news/article-1" }} → false
{{ fileExists "content/news/article-1.md" }} → true
{{ fileExists "news" }} → true
{{ fileExists "news/article-1" }} → false
{{ fileExists "news/article-1.md" }} → true
