Running default cargo new

[KarolStola]

Hi!

I want to create a template that just adds some files to the standard cargo new command. My first intuition is to use hooks to write a rhai script calling that, but I couldn't find any info on how to achieve it in it's documentation (I don't know rhai at all). Is there any other way to do that?

if you want to run cargo new as part of the template, it can be done using Rhai as you describe, but its a bit cumbersome...

Command line:

cargo generate --allow-commands <template>

Then you need the actual template with the files you want to add, as well as a Rhai script that does:

let output = system::command("cargo", ["new", "additinal args..."]);

NOTE: if the external command (cargo new in this case) requires any kind of input it will fail! This is by design, and is a current known limitation.

... if it was me, considering that cargo new doesn't give you much to start with, I wouldn't bother! Just add the few files including the cargo new output to a small template and call it a day. Running cargo from within the template is still a security issue (hence the need for the --allow-commands flag), and should really be avoided unless absolutely required - and in this case the external command does not give you any advantage to just add the files to the actual template.
