#
|

# goipath the packaged Go project import path
|

#
|

# The following spec variables SHOULD be set before calling the macro:
|

#
|
||
# forgeurl the project url on the forge, strongly recommended, if it can not
|
||
# be deduced from goipath; alternatively, use -u <url>
|
||
# Version if applicable, set it with Version: <version>
|
||
# tag if applicable
|
||
# commit if applicable
|
||
#
|
||
# The macro will attempt to compute and set the following variables if they are
|
||
# not already set by the packager:
|
||
#
|
||
# goname an rpm-compatible package name derived from goipath
|
||
# gosource an URL that can be used as SourceX: value
|
||
# gourl an URL that can be used as URL: value
|
||
#
|
||
# It will delegate processing to the forgemeta macro for:
|
||
#
|
||
# forgesource an URL that can be used as SourceX: value
|
||
# forgesetupargs the correct arguments to pass to %setup for this source
|
||
# used by %forgesetup and %forgeautosetup
|
||
# archivename the source archive filename, without extentions
|
||
# archiveext the source archive filename extensions, without leading dot
|
||
# archiveurl the url that can be used to download the source archive,
|
||
# without renaming
|
||
# scm the scm type, when packaging code snapshots: commits or tags
|
||
#
|
||
# If the macro is unable to parse your forgeurl value set at least archivename
|
||
# and archiveurl before calling it.
|
||
#
|
||
# Most of the computed variables are both overridable and optional. However,
|
||
# the macro WILL REDEFINE %{dist} when packaging a snapshot (commit or tag).
|
||
# The previous %{dist} value will be lost. Don’t call the macro if you don’t
|
||
# wish %{dist} to be changed.
|
||
#
|
||
# Optional parameters:
|
||
# -u <url> Ignore forgeurl even if it exists and use <url> instead. Note
|
||
# that the macro will still end up setting <url> as the forgeurl
|
||
# spec variable if it manages to parse it.
|
||
# -s Silently ignore problems in forgeurl, use it if it can be parsed,
|
||
# ignore it otherwise.
|
||
# -p Restore problem handling, override -s.
|
||
# -v Be verbose and print every spec variable the macro sets.
|
||
# -i Print some info about the state of spec variables the macro may use or
|
||
# set at the end of the processing.
