## Welcome to **Mold**
> **MOLD**: *Meta-variable Operations for Lean Development*
Mold is a Template Processor, or Template Engine, to work with repository
templates. The main motivation of Mold is to have repositories in GitHub used
as template repositories to create new, customized repositories for other
users.
Mold is the CLI wrapper of the [mold_lib](https://github.com/rocher/mold_lib),
the Ada library that implements all Mold functionality.
Main features supported in Mold include
* variable replacement in mold files (*.mold)
* definition of variables with a simple TOML file
* for a given directory, variable replacement recursively for all mold files
in all subdirectories
* variable replacement in filenames
* variables in variables
* predefined text filters (and custom text filters)
* inclusion of other templates
Variable replacement can be specified as *normal*, *optional* or *mandatory*.
For example, the variable `foo = "bar"` can be specified with `{{foo}}`,
`{{?foo}}` (optional) or `{{#foo}}` (mandatory). The difference is the handling
of errors when an undefined variable is encountered.
All mold files must end with the extension `.mold`, for example
`README.md.mold`. Destination files (with variables replaced) have the same
name without the mold extension: `README.md`. This simplifies the work done in
large subdirectories with few templates.
This crate contains the Ada library and unit tests. For a CLI tool, please
take a look at the crate `mold`.
