## Using the REPL
|
||||
|
||||
To enter the `hnix` REPL use
|
||||
|
||||
```
|
||||
hnix --repl
|
||||
```
|
||||
|
||||
To evaluate an expression and make it available in the REPL
|
||||
as the `input` variable use
|
||||
|
||||
```
|
||||
hnix --eval -E '(import <nixpkgs> {}).pkgs.hello' --repl
|
||||
```
|
||||
|
||||
Use the `:help` command for a list of all available REPL commands.
|
||||
|
||||
## Building with full debug info
|
||||
|
||||
To build `hnix` for debugging, and with full tracing output and stack traces,
