Embed an external codefile as a code-block. The codefiles must be located inside the Obsidian vault.
Create a code-block with the tag codefile
and a single line which is a
path to the file to be loaded:
```codefile
path/relative/to/vault/main.cpp
```
In the reading view, the file will be loaded from disk and rendered as a code-block.
Prepend the path with a code-language and a :
to enable language syntax
highlighting:
```codefile
cpp:path/relative/to/vault/main.cpp
```
