Ability to Template Files

[dolfelt]

We currently use an internal tool very similar to go-task. I'd like to replace it, however it has the ability to template files. It has a special command that allows files, --vars and --varFiles to be passed in, templated using Go templates (and sprig) and output to stdout.

This is especially useful for extending configuration files and providing a bit more power of Go templates and variables based on environments, parameters, etc.

Does anyone have thoughts on how to go about this or how it might specifically be implemented in go-task?

Thanks!

I found this tool which seems to pair nicely with what we are trying to do.

I was a bit in doubt on how it worked without an example, but it's good you find a way to do what you need. 🙂

@andreynering Is there a way to print out all the variables to a yaml format I could pipe into this gomplate tool? That would greatly simplify the flow of data and commands. For example echo "{{.YAML_VARS}}" | gomplate | kubectl -f -

I am also interested in creating files with task (wonderful tool by the way).

I did something similar then the example here: https://taskfile.dev/#/usage?id=gos-template-engine

It creates a file using cat. This works fine until a college from me run the task on windows.

Do you think it would be possible to add the possibility to create/replace files? For example

cmds:
- file: |
        content of file

Regarding the lack of some shell builtins on Windows (including cat), there's a main issue here: #197.
