`makeScriptWriter` returns a derivation which creates an executable script.
|
|
|
|
# Inputs
|
|
|
|
config (AttrSet)
|
|
: `interpreter` (String)
|
|
: the [interpreter](https://en.wikipedia.org/wiki/Shebang_(Unix)) to use for the script.
|
|
: `check` (String)
|
|
: A command to check the script. For example, this could be a linting check.
|
|
: `makeWrapperArgs` (Optional, [ String ], Default: [])
|
|
: Arguments forwarded to (`makeWrapper`)[#fun-makeWrapper].
|
|
|
|
`nameOrPath` (String)
|
|
: The name of the script or the path to the script.
|
|
|
|
When a `string` starting with "/" is passed, the script will be created at the specified path in $out.
|
|
I.e. `"/bin/hello"` will create a script at `$out/bin/hello`.
|
|
|
|
Any other `string` is interpreted as a filename.
|
|
It must be a [POSIX filename](https://en.wikipedia.org/wiki/Filename) starting with a letter, digit, dot, or underscore.
|
|
Spaces or special characters are not allowed.
|
|
|
|
`content` (String)
|
|
: The content of the script.
|
|
|
|
:::{.note}
|
|
This function is used as base implementation for other high-level writer functions.
|
|
|
|
For example, `writeBash` can (roughly) be implemented as:
|
|
|
|
```nix
|
|
writeBash = makeScriptWriter { interpreter = "${pkgs.bash}/bin/bash"; }
|
|
```

## `pkgs.writers.makeScriptWriter` dash example

|
|
-> /nix/store/indvlr9ckmnv4f0ynkmasv2h4fxhand0-hello
|
|
```
|
|
|
|
The above example creates a script named `hello` that outputs `hello world` when executed.

```sh
