# Package.yml
All packages consist of a single build file, which provides all of the required metadata for the package manager, plus the build steps involved to produce a package. This follows the YAML specification.
## Format
All `package.yml` files **must** be valid YAML.
As can be seen in the example below, the file is organised into a key->value hierarchy. Some values may be required to be in a list format, whereas most are simple strings. The build step sections are all considered optional, however if you do not
perform *any* steps, then no package is generated. Each of these keys contains content that will be placed within a script and executed within a controlled environment to perform the package build. To all intents and purposes, they are bash scripts
with a predefined environment.
An example file follows:
``` yaml
name : nano
version : 2.5.1
release : 39
source :
- http://www.nano-editor.org/dist/v2.5/nano-2.5.1.tar.gz : e06fca01bf183f4d531aa65a28dffc0e2d10185239909eb3de797023f3453bde
license :
- GPL-3.0
component : editor
summary : Small, friendly text editor inspired by Pico
description : |
GNU nano is an easy-to-use text editor originally designed as a replacement for
Pico, the ncurses-based editor from the non-free mailer package Pine.
setup : |
%configure --enable-utf8 --docdir=/usr/share/doc/nano
build : |
%make
install : |
%make_install
# TODO: Convert to stateless
install -D -m 00644 $pkgfiles/nanorc $installdir/etc/nanorc
```
## Keys
Not all fields in `package.yml` are mandatory, but a small selection are. They are listed below. Note that `string(s)` indicates that it is possible to use a `list` of strings, or one single `string`
`dict` refers to a `key : value` split in YAML, and `dict(s)` refers to a list of `dict`s
### Mandatory Keys
Key Name | Type | Description
---- | ---- | ----
**name** | `string` | The name of the package. This is also used as the base of all sub-package names. Unless unavoidable, this should match the upstream name
**version** | `string` | The version of the currently packaged software. This is taken from the tarball in most cases.
**release** | `integer` | Specifies the current release number. Updates in the package number are based on this `release` number, *not* the `version` number. As such, to release an update to users, this number must be incremented by one.
**license** | `string(s)` | Valid upstream license(s). Try to ensure these use [SPDX identifiers](http://spdx.org/licenses/).
**source** | `dict(s)` | Upstream source location (i.e. tarball), with the valid `sha256sum` as a value
**component** | `string` | Component / group of packages this package belongs to. Check available components via `eopkg lc`
**summary** | `string` | Brief package summary, or display name
**description** | `string` | More extensive description of the software, usually taken from the vendor website
### Optional, supported keys
Key Name | Type | Description
---- | ---- | ----
**clang** | `bool` | Set to `no` if this package cannot be built with Clang
**extract** | `bool` | Set to `no` to disable automatic source extraction.
**autodep** | `bool` | Set to `no` to disable automatic binary dependency resolution at build time
**emul32** | `bool` | Set to `yes` to enable an `-m32` build (32-bit libs)
**libsplit** | `bool` | Set to `no` to disable splitting of libraries into `devel` sub-packages
**rundeps** | `dict(s)` | Specify further runtime dependencies for the packages
**replaces** | `dict(s)` | Replace one package with another, used when renaming or deprecating packages for clean upgrade paths
**patterns** | `dict(s)` | Allows fine grained control over file placement within the package or sub-packages. Useful for packages that are development only (i.e. `/usr/bin` files)
### Build step keys, optional
Note that each step in itself is optional, however all can be used. The value of each of these keys is merged into a build script that is executed for each stage of the build.
Step Name | Description
---- | ----
**setup** | Performed after the source extraction. This is the correct place to perform any `configure` routine, or to `patch` the sources.
**build** | Use this step to run the build portion, i.e. `make`
**install** | This is where you should install the files into the final packaging directory, i.e. `make install`
**check** | There is where tests / checking should occur, i.e. `make check`
## Macros
To further assist in packaging, a number of macros are available. These are simply shorthand ways to perform a normal build operation. They also ensure that the resulting package is consistent. These macros are only available in our build steps, as
they are substituted within the script before execution.
### Usage
Macros are prefixed with `%`, and are substituted before your script is executed. Macros ending with `%` are used to provide directory names or build values, to the script.
``` bash
# Run the configure macro with the given arguments
%configure --disable-static
```
### Actionable Macros
Macro | Description
---- | ----
**%autogen** | Runs autogen with our `%CONFOPTS%` to create a configure script then proceeds to run `%configure`.
**%cmake** | Configure cmake project with the distribution specific options, such as prefix and release type
**%configure** | Runs `./configure` with our `%CONFOPTS%` variable macro.
**%make** | Runs the `make` command with the job count specified in `eopkg.conf`
**%make_install** | Perform a `make install`, using the `DESTDIR` variant. Should work for the vast majority of packages.
**%patch** | Sane patch macro to run in batch mode and not contaminate source tree on failure
**%apply_patches** | Applies all patches listed in the `series` file in `./files` folder.
**%reconfigure** | Updates build scripts such as `./configure` and proceeds to run `%configure`.
### Haskell Actionable Macros
Macro | Description
---- | ----
**%cabal_configure** | Runs cabal configure with prefix, libdir, etc. and ensures the necessary package.conf.d is copied to the correct location.
**%cabal_build** | Runs cabal build with `%JOBS%`
**%cabal_install** | Runs cabal copy to `$installdir`
**%cabal_register** | Runs cabal register to generate a pkg-config for package and version, then installs the conf file.
### Meson Actionable Macros
Macro | Description
---- | ----
**%meson_configure** | Runs meson with our CFLAGS and appropriate flags such as libdir.
**%meson_build** | Runs ninja and passes our `%JOBS%` variable.

**$pkgfiles** | Refers to the `./files` directory relative to the `package.yml` file
**$sources** | Refers to the directory where your source files are stored e.g. `$sources/nano.tar.gz`
## Types
The `package.yml` file uses native YAML types, however for the sake of clarity an explanation of how they are used within the context of `ypkg` is provided below.
### string
This is simply text, which does not need to be quoted.
### integer
Whole, positive number, used in the `release` field.
### list
A YAML list (or array) can be expressed in multiple ways. A short array-notation would look like this:
`[one, two, three]`
They can also be expressed like this:
``` yaml
- First Value
- Second Value
- Third Value
```
### dict
Known as an associative array, this is key to value mapping. These are separated by a colon (`:`), the token on the left is taken to be a key, and the token on the right is the value.
`SomeKey: Some Value`
Note that each `ypkg key` in the YAML file is actually a dict.
### dict(s)
This is a combination of the `list` type, the `dict` type and some assumptions. We primarily make use of this to express advanced information within the package. These permit you to provide no key, and a value only.
In this instance, the key is assumed to be the package `name`:
`- some value`
An explicit key, usually a sub-package name:
`- somekey: somevalue`
A mix of both:
``` yaml
- somevalue
- somekey: another value
```
The values may also be expressed in list form, still using the same default key logic:
``` yaml
- [one,two, three]
- somekey: [one,two, three]
- key:
- value one
- value two
- value three
```
