rbm input files configuration


When building a project with rbm, the input can be a git or mercurial repository from which a tarball will be created and used as input for your build. In addition or instead of this git or mercurial repository, it is possible to retrieved files from other sources to use them as input files.

The following input sources are available:

The file that has been retrieved can be verified with:

The input files can be located in the output directory (for the result of an other project’s build), or in the project’s directory.


The configuration of the input files is done in the input_files configuration option. This option is an array of file descriptors. Each file descriptor is an hash containing some of the following options:


The name of the file that will be fetched. Except when an URL or a project is set, this filename is mandatory. If it is not set when an URL is set, the basename of the URL is used as a filename. If it is not set when a project is set, the project’s filename option is used. The filename can be the name of a directory, in which case all the files from the directory are included.


Optionaly the input_file can have a name. This name is used as key in the input_files_by_name option.


The content of the file.


The URL from which to download the file.


A command or script to execute to produce the file.


The name of an other project to build, to create the file. The content of the file descriptor is used as options for the build of this project. You can add config options such as version, git_hash or target to configure the build. The command line options are not forwarded. The name of the current project is available to that other project in the origin_project option, and the current step in the origin_step option.


When the input file is an other project, this option can be used to select a different type of build (which we call a step). This is equivalent to the --step command line option. The previous step is available in the origin_step option.


An array defining the build targets for the selected project. If this option is not set, the current build target is forwarded. If set, this replaces the current targets.


The same as target, but instead of replacing the current targets, the new targets are appended.


The same as target, but instead of replacing the current targets, the new targets are prepended.


A hash table containing targets to replace. The key is a regular expression, and the value the replacement. See perlre manual page for details about the syntax. Note that referencing capture groups in the replacement is currently not supported.


The files are enabled by default. If this option is set to 0, then the file is ignored.


By default, if the file is already present, it is not downloaded or created again, except when an sha256sum is defined and the file present is not matching. If this option is set to a true value, the file will be removed and created again on each run, except when an sha256sum is defined and the file present is matching.


The sha256 checksum of the file. The build will fail with an error if the file does not match the expected sha256 checksum. If the value is empty, the checksum is not checked.


If this option is set to 1, the file is checked for a gpg signature. If it is set to an other non zero value, or an array of non zero values, those are expected to be the valid gpg key IDs. The gpg_wrapper, gpg_keyring, gpg_bin, gpg_args options can be used to configure the gpg check. Those options can be overriden in the file descriptor.


An array of file extensions for the gpg signature file. Those extensions are used to find the signature file when file_gpg_id is set. If the signature file is missing but an URL is set, the extension is appended to the URL to try to download it. The default value for sig_ext is gpg, asc, sig. The sig_ext can also be set to a single value.


A command or script to be used to download files from an URL. It should use filename as the output filename, and URL as the source URL. The default is to use wget.


By default, the files are searched in the project’s directory, and its output directory. The generated files are stored in the project’s output directory. If you want to store and search a file in a different directory, you can set the output_dir option to a different value.

All those options are templates, and can use other options defined inside or outside the file descriptor. Their default values can be defined outside the file descriptor.

Those options can also be defined per target, or per distribution.

Instead of a file descriptor hash, an element of the input_files array can be a string. In that case the string is the name of the option containing the file descriptor hash. This can be useful when you are using the same file in multiple projects.

Inheritance of Projects Options

When defining a file of type project, the options defined in the input_files entry are transmitted to the child project. If this project is also using other projects in its input_files then the options from the first input_files entry are inherited.

In this example, both project B and C are getting the definition of option1:

    - project: B
      option1: value1

    - project: C

  input_files: []

In some cases you might want to define options that only apply to the first level of child projects. To do that you can define the options under norec. In this example, only project B is getting the definition of option1:

    - project: B
        option1: value1

    - project: C

  input_files: []


In the following example we define the input_files configuration for the project bundle. This project has two different targets, dev and stable, and is using input files from different sources :

 - filename: project-A.tar.gz
   URL: http://www.project-a.org/project.tar.gz
   sha256sum: 93c4fb2f3d377f41001fe1cf3c806dc9fc926a53dbbf4302838d7ee7c9f17315
 - filename: 'project-B-[% c('project_b_version') %].tar.gz'
   URL: 'http://www.project-b.org/project-b-[% c('project_b_version') %].tar.gz'
       project_b_version: 0.12
       sha256sum: 5f0ac48598c0a7948bb7da626b0599f121c1365ec53b111b5ba9e9330410fc44
       project_b_version: 0.10
       sha256sum: f0f81fbc84992c21bbbcb301c1185ce3d1772f150f57d37530cc9e4b0249a630
 - filename: project-c.tar.gz
   URL: http://www.project-c.org/release-0.1.tar.gz
   file_gpg_id: 1
   gpg_keyring: project-c.gpg
   sig_ext: sig
 - filename: project-D.tar.gz
   project: project_d
   pkg_type: build
       git_hash: master
       git_hash: 2.1
       tag_gpg_id: 1
