yal-cmd 0.1.1

Yalla Nkardaz’s personal CLI toolkit

YAL

YAL is a command-line utility for project initialization and updates based on templates.

Commands

• yal create <kind>[:<name>][@<ref>] — uses a template to create a new project; if name is not specified, the default template will be used
• yal update <kind>[:<name>] — downloads and caches the latest version of a template
• yal add <kind>:<name>[@<ref>] from <repository URL | user/repo> — registers an external template from GitHub with the specified name
• yal remove <kind>[:<name>[@<version>]] — removes a template from the local storage; if name is not specified, all templates of the given kind will be removed

---

Create a project

Downloads the template (if not cached locally) and initiates the configuration process.

# Basic usage — uses the "default" template, latest version
yal create book

# Specify a template by name
yal create book:my-theme

# Specify a version (release tag or commit hash)
yal create book@1.7.1
yal create book@c651f7d

# Combined
yal create book:my-theme@1.7.1

If the requested version is already cached locally, YAL skips the download. If no version is specified, YAL uses the most recent locally cached version; if none is cached, it downloads the latest release (or the latest commit if the repository has no releases).

---

Update a template

Downloads and caches the latest version of a template without creating a project. Useful for pre-caching before working offline.

yal update book
yal update book:my-theme

---

Add an external template

Registers a GitHub repository as a named template under a given kind, then downloads it.

# Register and download the latest release (or commit)
yal add book:my-theme from https://github.com/user/my-book-template

# Register a specific version
yal add book:my-theme@1.2.0 from https://github.com/user/my-book-template

After registration the template is available like any built-in one:

yal create book:my-theme
yal update book:my-theme

Registered templates are stored in ~/.yal/user-templates.toml. Downloaded files go to ~/.yal/user-templates/<kind>/<name>/<version>/.

---

Remove a template

Removes cached template files from local storage. When all versions of a user-registered template are removed, its registry entry is also deleted.

# Remove all cached versions of all "book" templates
yal remove book

# Remove all cached versions of a specific template
yal remove book:default
yal remove book:my-theme

# Remove a specific version only
yal remove book:default@1.7.1
yal remove book:my-theme@c651f7d

---

yal.toml

A configuration file placed in the root of the created project. It stores metadata about the template used and lets you define local commands for the project.

[origin]
template         = "book"
template-version = "9670322"          # commit hash, or a release tag like "1.7.1"
created-at       = "2026-05-31T03:16:33Z"
yal-version      = "0.1.1"

[[command]]
name      = "make"
script    = "/build/build.py"         # leading "/" = project root, not filesystem root
exec      = "python3"
arguments = { --mode = [] }           # [] means any value is accepted
# yal make              → python3 build/build.py
# yal make --mode=print → python3 build/build.py --mode=print

[[command]]
name   = "make print"
macros = "make --mode=print"
# yal make print → expands to → yal make --mode=print

If yal.toml is not present in the template, it will be created automatically with a default [origin] section filled in on project creation.

Commands

Each [[command]] entry supports:

Field	Description
name	Command name as typed on the CLI (spaces allowed for multi-token names)
script	Path to the script file. Leading / is relative to the project root
exec	Interpreter: python3, node, bash, os-bash, etc. Auto-detected from file extension if omitted
arguments	Allowed flags and their accepted values. Empty list [] accepts any value
macros	Expands to another command instead of running a script

exec = "os-bash" uses bash -c on Unix and cmd /c on Windows.

Arguments are passed as --key=value or --key value:

yal make --mode=print
yal make --mode print

---

yal.template.toml

A configuration file placed in the root of a template repository. When present, YAL uses it to interactively prompt the user for values during yal create, then applies them to target files in the new project.

[meta]
yal-min-version = "0.1.1"
post-commands   = ["npm install"]    # run after project is created
exclude         = ["examples/"]      # paths not copied into the project

[[fields]]
id             = "project-name"
type           = "text"
required       = true
is-folder-name = true                # this value becomes the output folder name

[[fields]]
id      = "author"
type    = "text"
default = "Anonymous"

[[fields]]
id      = "license"
type    = "text"
options = ["MIT", "Apache-2.0", "GPL-3.0"]
default = "MIT"

[messages]
project-name.prompt      = "Project name"
author.prompt            = "Author name"
author.placeholder       = "Your Name"
license.prompt           = "License"

[messages.ru]
project-name.prompt = "Название проекта"
author.prompt       = "Имя автора"

Fields

Each [[fields]] entry supports:

Field	Description
id	Unique identifier, used as key in mappings and message lookups
type	Input type; currently text
required	If true, the user must provide a non-empty value
default	Default value used if the user presses Enter without typing. Use "{placeholder}" to mirror the placeholder
options	If non-empty, restricts accepted values to this list
is-folder-name	If true, the field's value becomes the name of the created project folder

Targets

After collecting field values, YAL writes them into files specified under [[targets]]:

[[targets]]
file   = "/config/meta.yaml"
format = "yaml"

  [[targets.fields]]
  key   = "project.name"          # dot-separated YAML path
  field = "project-name"          # use value from [[fields]] id="project-name"

  [[targets.fields]]
  key   = "project.created"
  value = "${DATE}"               # built-in generator

  [[targets.fields]]
  key   = "project.uuid"
  value = "${UUID}"

  [[targets.fields]]
  key   = "meta.copyright"
  value = "© {author}, ${YEAR}"  # interpolation + generator

Built-in generators

Syntax	Output
${UUID}	Random UUID4
${DATE}	Current date YYYY-MM-DD (UTC)
${YEAR}	Current year
${MONTH}	Current month
${DAY}	Current day
${TIMESTAMP}	Unix timestamp (seconds)
${RANDOM}	Random integer 0 – 2³¹−1
${NULL}	Sets the YAML key to ~ (null)

Field values can be interpolated with {field-id} syntax and combined freely with generators: "© {author}, ${YEAR}".

Localization

Messages support per-language overrides. YAL detects the system locale automatically and falls back to the base (top-level) messages if no translation is found for the current language.

[messages]
project-name.prompt = "Project name"    # base (fallback)

[messages.ru]
project-name.prompt = "Название проекта"

---

Built-in templates

<Book> Typst Book Template

• Repo: https://github.com/DemerNkardaz/Typst-Book-Template
• Name: default
• Use: yal create book

A template for creating a book using Typst, including a prebuilt structure, plugins, styles, settings, and a build system combining Typst and Python tools.

Requirements: Typst compiler and the following Python packages:

pip install pyyaml pikepdf pillow

---

Custom templates

Any public GitHub repository can be registered as a template. The repository does not need to contain a yal.template.toml — YAL will copy it as-is and create a default yal.toml in the resulting project.

# Register under a new kind "vue", name "default"
yal add vue:default from <user>/my-vue-template

# Create a project from it
yal create vue

You can register multiple named templates under the same kind:

yal add vue:tailwind from <user>/vue-tailwind-template
yal add vue:minimal  from <user>/vue-minimal-template

yal create vue:tailwind
yal create vue:minimal

Full example with yal.template.toml

[meta]
yal-min-version = "0.1.1"
post-commands   = ["git init", "npm install"]

[[fields]]
id             = "project-name"
type           = "text"
required       = true
is-folder-name = true

[[fields]]
id      = "author"
type    = "text"
default = "{placeholder}"

[[targets]]
file   = "/package.json"
format = "json"

  [[targets.fields]]
  key   = "name"
  field = "project-name"

  [[targets.fields]]
  key   = "author"
  field = "author"

[messages]
project-name.prompt      = "Project name"
author.prompt            = "Author"
author.placeholder       = "Your Name"

Local storage layout

~/.yal/
  templates/                      # built-in template cache
    <kind>/
      <name>/
        <version>/
          yal-meta.json
          ...template files...

  user-templates/                 # user-registered template cache
    <kind>/
      <name>/
        <version>/
          yal-meta.json
          ...template files...

  user-templates.toml             # user registry (managed by yal add / yal remove)

yal-meta.json stores the kind, name, version, source type (release or commit), repository URL, release date, and install date for each cached template.

Authentication

For private repositories or to avoid GitHub API rate limits, set a personal access token:

export GITHUB_TOKEN=ghp_...
# or
export GH_TOKEN=ghp_...
