Main features

  • project generator as a standalone executable (no shared/system dependencies (so no python + pip + ...))
  • a simple and generic project template (no specialisation to one ecosystem)
  • template as simple as possible, like a
    • copy or clone with file/folder renames without overwrite
    • few search and replace into file
  • template hosted as a local folder on the file system
  • template hosted as a git repository on any host (not only public github)
    • at root of the repository
    • in subfolder of the repository
    • in any revision (branch, tag, commit)
  • template composed of other template
    • composite template are regular standalone template
    • composite template can be apply at root folder
  • a fast enough project generator

Sub features

  • dry mode (usefull to test)
  • chain template generation because fragment of templates can be commons
  • chain commands (eg: 'git init') (like a post-hook)
    • raw command
  • composite template can be apply at root folder
  • composite template include under conditions
  • file / folder ignored under conditions
  • handlebars helpers
    • transform strings (toUpperCase, toLowerCase, Capitelize,...)
    • render content of GET url
    • render content from https://gitignore.io
    • suggestions welcomes ;-)


Some of the following limitations could change in the future (depends on gain/loss):

  • no conditionnals file or folder creation
  • no update of existing file or folder
  • no specials features
  • no plugin and not extensible (without change the code)
  • handlebars is the only template language supported (support for other is welcome)

      - copyraw "my_project/file_6.hbs"

Create a template


  • The minimal template is an empty dir.

  • a sample template and its expected output (on empty folder) is available at tests/test_1.

  • file priority (what file will be used if they have the same destination path)

    existing file
    file with source extension .ffizer.hbs (and no {{...}} in the source file path)
    file with identical source file name (and extension)
    file with {{...}} in the source file path

A 5 minutes tutorial

  1. create the folder with the template

    mkdir my-template
    cd my-template
  2. add file that will be copied as is

    cat > file0.txt <<EOF
    I am file0.
  3. add a template file that will be "rendered" by the handlebars engine

    cat > file1.txt.ffizer.hbs <<EOF
    I am file1.txt of {{ project }}.
  4. add a ffizer configuration file (.ffizer.yaml)

    • to list variables
    • to list pattern to ignore
      - name: project
        default_value: my-project
      - .git # exclude .git of the template host
  5. add a file with a name that will be "rendered" by the handlebars engine

    cat > '{{ project }}.txt' <<EOF
    I am a fixed content file with rendered file name.

Template Helpers / Functions

Helpers extend the template to generate or to transform content. Few helpers are included, but if you need more helpers, ask via an issue or a PR.

To use an helper:

{{ helper_name argument}}

see Handlebars templating language

String transformation

for the same input: "Hello foo-bars" helper_name | example out -- | -- to_lower_case | "hello foo-bars" to_upper_case | "HELLO FOO-BARS" to_camel_case | "helloFooBars" to_pascal_case | "HelloFooBars" to_snake_case | "hello_foo_bars" to_screaming_snake_case | "HELLO_FOO_BARS" to_kebab_case | "hello-foo-bars" to_train_case | "Hello-Foo-Bars" to_sentence_case | "Hello foo bars" to_title_case | "Hello Foo Bars" to_class_case | "HelloFooBar" to_table_case | "hello_foo_bars" to_plural | "bars" to_singular | "bar"

Http content

Helper able to render body response from an http request.

helper_name usage
http_get http_get "http://hello/..."
gitignore_io gitignore_io "rust"

  • Cookiecutter, lot of templates, require python + pip + install dependencies on system (automatic)
  • Cookiecutter — Similar projects
  • sethyuan/fgen: A file generator library to be used to generate project structures, file templates and/or snippets. Templates are based on mustache. require nodejs
  • project_init in rust, use mustache for templating but I have some issues with it (project template creation not obvious, github only, plus few bug) I could contributes but I have incompatible requirements (and would like to create my own since a long time).
  • skeleton, good idea but no template file, more like a script.
  • porteurbars, very similar but I discover it too late.
