How does templating for rotz work ?

[aniketgm]

I'm am aware about Jinja. So I believe handlebars is somewhat similar. But how does this work for multiple defaults. I mean, let's say, I want to setup my config as below:

windows:
  winget:
    installs: winget install {{ name }}
  scoop:
    installs: scoop install {{ name }}

Is this possible ?

Also, from here, it says,

These files contain defaults which are automatically used in sub directories for empty keys in the dot.yaml files.

And my config is like this:

So, how to set the empty keys:
Like this ?

windows:

Or like this:

windows:
  installs:

Because both does not work for me.

Hey, you can not have multiple different install commands in the defaults.

you'll have to decide which of the two you'll want as the default.

you can setup your dotfiles directory like this:

├── defaults.yaml
├── some
│   └── dot.yaml
└── other
    └── dot.yaml

# defaults.yaml
windows:
  installs: winget install {{ name }}

the some/dot.yaml file is empty and uses the winget install command from the defaults.

this file overwrites that and uses scoop.

# other/dot.yaml
windows:
  installs: scoop install {{ name }}

Another option is to have two subfolders with different defaults.

├── winget
│   ├── defaults.yaml
│   └── some
│       └── dot.yaml
└── scoop
    ├── defaults.yaml
    └── other
        └── dot.yaml

# winget/defaults.yaml
windows:
  installs: winget install {{ name }}

# scoop/defaults.yaml
windows:
  installs: scoop install {{ name }}

the winget/some/dot.yaml file is empty and uses the winget install command from the defaults.

the scoop/other/dot.yaml file is empty and uses the scoop install command from the defaults.

Thank you @volllly for this detailed explanation. This clears out much of my doubts.

Just one more question related to templating:

I have a folder called essentials >> packages. In the packages folder, I have a defaults.yaml file with both linux and windows default commands (as shown below). I was wondering, how do I configure this such that the ones with Microsoft.Powershell, etc. will be run for windows and the build-essential, etc. is run for linux, when I run say: rotz install essentials/packages
Note: all the folders inside packages folder are with empty dot.yaml files.

Now the thing is, here I could create two separate folders packages_win and packages_lin for windows and linux packages separately. where I have to separate out the defaults as well. But, then I feel like it defeats the purpose of the feature of having both windows and linux configs in same dot file.

So what can we do here. It would helpful if we could mention something inside the empty dot.yaml file, for e.g. inside the Microsoft.PowerShell/dot.yaml, we could mention something like just one entry windows: and nothing else, so that we know this needs to be run for windows default and similarly inside the build-essential/dot.yaml -> just the entry linux: to run the default commands. What do you think ?

glad this cleared things up 😁

You can set the respective installs keys to false if you want to skip them.

So in the Microsoft.Powershell/dot.yaml file you can disable linux install like this:

linux:
  installs: false
