Templato

Templato is an extremely simple command line program for using template files.

Templato is great for general-purpose use, due to its speed and the simple syntax of the actual command line arguments.

Installation

Cargo

Templato is available on Crates.io, and may be installed through Cargo:

cargo install templato

Nix Flake

Templato also has a Nix Flake available for use. Add the repository as an input to your system flake:

inputs.templato = {
  url = "git+https://codeberg.org/r6915ee/templato";
  inputs.nixpkgs.follows = "nixpkgs";
};

You can then make use of the package provided by the Flake by using inputs.templato.packages.arch.default, where arch is the current CPU architecture used by the system.

{
  inputs
}:
{
  environment.systemPackages = {
    (inputs.templato.packages.x86_64-linux.default)
  };
}

Usage

Basic

Templato relies on search paths to search for templates. These function like the paths in the PATH environment variable, but allow for searching for text files instead of executable ones. The default search path is ~/Templates, assuming that ~ is the home directory.

A template file is a generic text file that contains the actual template data to copy. Its contents are copied over to the output file.

Assuming you have a template named lua/module.lua in your search paths, you can simply run the following command:

templato lua/module.lua

This will copy the template over to the current directory. Do note that there is a scheme for what filename is used for the output file; if a custom filename is specified using the optional, second argument, then that filename is used. If this argument isn't specified, then Templato will attempt to use the base filename of the template, or it will use a default template filename if the filename could not be extracted for whatever reason.

Advanced

To configure search paths, Templato uses command line flags and a dedicated TEMPLATO_SEARCH_PATHS environment variable. The command line flags, --prepend and --append, will prepend and append a search path, respectively. These flags can be used multiple times.

The TEMPLATO_SEARCH_PATHS environment variable, if present, will override the default home directory search path with the paths present in the environment variable. The contents of the environment variable follow the same delimiter rules as the current operating system, where each path is split through a delimiter; on Windows, this delimiter will be a semicolon (;), while other systems will typically use a colon (:). This environment variable can be safely used with both flags above.

The order of search paths matters, because Templato will use the first template it finds in the search paths. Prepending in this case can be useful in order to force Templato to use that search path first.
