Service publishing workflow is similar to activities. There is an info file, here service/service.info, which describes current status(not history) of development process. All these fields, finally, go to feed file while publishing new version. Service.info file is an analog of scenario files in regular GNU/Linux distributions like .spec files in RPM.

Sections

NOTE Section names are case sensitive.

[DEFAULT]

This section is required.

  • name, the identity of the service, this field defines name of feed's root directory on the server http://download.sugarlabs.org/services/ as well
  • summary, short descriptive line
  • description, long descriptive line, to wrap long text, all lines after second, should start with spaces
    could be omited to reuse summary field
  • license, in 0install, typically a Trove category, as used on freshmeat.net, but could be fedora names, since the rest of sugar uses them
  • homepage web link to project home page
  • any options that will be global variables see [1]

[Service]

This section describes parameters that should be taken into account only if service has 0install implementations(including source implementations) in contrast with pure wrappers around native packages.

Section contains:

  • version, used only for services with native versioning scheme
  • requires, for any arch and binary implementations, list of runtime services that should exist before using service
requires = <service-name> [<not-before-version>[-<before-version>]] [; ...]
  • binding, what environment variables, 0install should export to session which uses this service
binding = [prepend|append|replace] <variable-name> [<insert-text-to-prepand-variable-value>] [; ...]
  • exec, for applications, shell command which will be executed to start service
  • include, files to include to bundle which will be created for this section
  • exclude, files to exclude from bundle which will be created for this section
  • arch, makes sense only for binary services and can contain * for noarch and build for binaries
  • age optional libtool like age of service

[Build]

If service contains binary implementations, this section should present to describe building process.

Section contains:

  • requires, what services should be installed before building this one from sources
requires = <service-name> [<not-before-version>[-<before-version>]] [; ...]
  • exec, command how to build binaries
    Its value is a shell command, executed inside the build directory $BUILDDIR. It must compile the source in $SRCDIR, putting the final result (ready for distribution) in $DISTDIR. If this command starts to get complicated, you should move it to a script (either inside the main source archive or in a separate dependency) and just set this attribute to the command to run the script.
    NOTE: This command will be executed not only in service developer environment but also on user side if proper binary wasn't found, so do not use here any development related commands like autogen.sh
    For example, followed command builds regular autotools based project
exec = "$SRCDIR"/configure --prefix="$DISTDIR" CFLAGS="-O2" && make install-strip

[Maintain]

If service is not a wrap around upstream project i.e. there is no ready to use source tarball, this section will describe how to build source bundle.

Section contains:

  • requires, dependencies that are need to build source tarball e.g. vala(there is no need in vala compiler after creating source tarball)
  • exec, shell command, 0sugar will pick up newly created file in service root directory
    Shell command, executed from service root directory. If this command starts to get complicated, you should move it to a script and just set this attribute to the command to run the script.
    By default 0sugar just bundle entirely service directory excluding temporary files.
exec = ./autogen.sh && make distcheck
  • generate-documentation, if set, documentation project will be created on [2], for now only epydoc value is supported

[Packaged]

This section supplements [Service] if service implementation could be installed from native packaging system.

Section contains:

  • <distro-name>, name in native packaging system
<distro-name> = <alias-for-name>

Sub services

Service.info could contain several sub services in sections:

[(Service|Packaged)/<sub-section-name>]

For [Packaged], sub services make sense if there are devel packages in distribution. For [Service], it could be useful to split built installation directory to several bundles e.g. pure binary(which could have several variants for several platforms) and non-arch sub bundles.

Sub service sections contain the same options that particular main section contains.

To link to sub service, the full name should be used.

Include files to bundles

  • files, list of files that will be included to runtime bundle and won't be included to buildtime
    if glob-mask contains symbol /, it will be applied to the whole path string, otherwise only to file names
    if section exists, only mentioned files will be bundled to runtime tarball, otherwise all files except files from [Buildtime] section
files = <glob-mask> [; <glob-mask> ...]
