DAP Packaging guidelines

DevAssistant provides an easy extendability through Assistants. These assistants are normally distributed via the DevAssistant Package Index in the form of DAP (DevAssistant Package) files. If you want to include a DAP into the main Fedora repositories, you can do so. This document outlines the rules involved.

Note: Packaged DAPs only work with DevAssistant 0.10.0 and newer. They can not be used with DevAssistant versions 0.9.* packaged in Fedora 21 and earlier.

How to package a DAP

We recommend you use the tool dap2rpm, which creates a SPEC file from your DAP automatically. It is packaged in Fedora Rawhide and 21's repositories as dap2rpm.

Naming guidelines

Every (RPM) package name must start with devassistant-dap-, which is followed by the name of the Assistant itself, all lowercase. For example, the DAP named Openscad will be named devassistant-dap-openscad in the SPEC file. In this document, the second part of the name (i. e. the substring openscad) will be referenced as %{shortname}.
There is no difference between packages that provide Assistants, and those that provide only auxiliary files, snippets, metapackages etc.

Dependencies

All packages must Require devassistant-ui. This means that the user has at least one user interface for DevAssistant installed, so they can use the DAP without futher installing anything. No version specification is necessary as DevAssistant 0.10.1 is the first version ever to provide devassistant-ui.
Requires: devassistant is not allowed, as that would install more packages for DA than the user may intend or need.
All packages must have BuildRequires: devassistant-devel. (for macros, installation and checking)
Each package must Require packages that are specified in the file /meta.yaml in the section dependencies. These names, of course, must contain the devassistant-dap- prefix. These Requires are generated automatically by dap2rpm.

Architecture

All daps must be architecture independent, i. e. BuildArch: noarch.

Macros

The macro denoting the parent directory where the package files go is %{assistant_path}. This currently expands to /usr/share/devassistant.
The macro definitions of %install_assistant, %repack_assistant, and %check_assistant are provided by the package devassistant-devel.

Prep section

DAP must be unpacked with setup like other packages, it is not permissible to install the source DAP directly.
If needed, you may patch the source files in this section.

Build section

You must re-pack the (optionally patched) DAP in the %build section using the macro %repack_assistant. This is needed for installing and checking.

Install section

Files are installed via the %install_assistant macro
Using the above macro automatically creates a list of files stored in the file dap-list, which can then be used in the %files section.
If the package contains licensing files, they should be marked as such by running the %install_assistant macro with argument(s) -L LICENSE_FILE1 LICENSE_FILE2.... The licensing files must be stored only in the doc directory of the DAP.
If installed manually, the package files are installed into %{buildroot}%{assistant_path} in subdirectories conforming to the DAP layout, i. e. the assistants/crt/foo directory is installed into %{buildroot}%{assistant_path}/assistants/crt/foo.

Check section

You must run the %check_assistant macro in the %check section, and it must pass.
If run manually, you must run the command da pkg lint -w %{shortname}-%{version}.dap (or similar, if your package's name differs). The run must produce no errors. Warnings are permissible.

Files section

If the macro %install_assistant was used in the %install section, it is sufficient to provide the list of files to the %files section like this: %files -f dap-files. This is the default situation when using dap2rpm.
If done manually:
- Package's files and directories are installed into %{assistant_path}.
- Do not install everything like %{assistant_path}/*, list each folder separately. That includes subdirectories in %{assistant_path}/assistants, as shown in these examples:
  - Bad: %{assistant_path}/assistants/*
  - Good: %{assistant_path}/assistants/crt/%{shortname}
- The doc directory in the DAP should be installed via the %doc macro, in the same %{assistant_path} directory.
- The meta.yaml file must be installed as %{assistant_path}/meta/%{shortname}.yaml.

Directory ownership

The package devassistant-core owns the directory %{assistant_path} itself and the following subdirectories:
1. %{assistant_path}/{assistants,doc,files,icons,meta,snippets}
2. %{assistant_path}/{assistants}/{crt,twk,prep,extra}
3. %{assistant_path}/files/{crt,twk,prep,extra,snippets}
4. %{assistant_path}/icons/{crt,twk,prep,extra}
The RPM-packaged DAP must own the following files/directories if and only if they are present in the upstream DAP:
- directories named %{shortname} in directories listed in point 2 and 3 of the previous bullet.
  - Example 1: %{assistant_path}/assistant/crt/%{shortname}
  - Example 2: %{assistant_path}/files/snippets/%{shortname}
- files named %{shortname}.yaml in the directories listed in point 2.
- a directory named %{shortname} in the directory %{assistant_path}/doc/
- a file named %{shortname}.yaml in the directory %{assistant_path}/meta/
- a file named %{shortname}.$SUFFIX, where $SUFFIX is an image file suffix (preferably PNG or SVG), in the directories listed in point 4.

%description
This assistants helps you to create new OpenSCAD project for 3D printing.
We use it in our 3D printing lab to store our 3D printers on Github.

Projects created with this assistant have a `Makefile` to build the 3D models form OpenSCAD sources.
To do so, run `make`. You can also generate the images by `make images` or print plates with `make arrange`.
Observe the generated `Makefile` to see all available options.
