32 # @DEFAULT_UNSET
33 # @DESCRIPTION:
34 # If non-empty this variable enables support for git submodules in our

48
49 # @ECLASS-VARIABLE: EGIT_PROJECT
50 # @DESCRIPTION:
51 # Variable specifying name for the folder where we check out the git

55 # EGIT_PROJECT="${EGIT_REPO_URI##*/}"
56
57 # @ECLASS-VARIABLE: EGIT_DIR
58 # @DESCRIPTION:
59 # Directory where we want to store the git data.

77 # If non-empty this variable prevents performance of any online
78 # operations.
79
80 # @ECLASS-VARIABLE: EGIT_BRANCH

82 # Variable containing branch name we want to check out.
83 # It can be overriden via env using packagename_LIVE_BRANCH
84 # variable.
85 #
86 # EGIT_BRANCH="${EGIT_MASTER}"
87
88 # @ECLASS-VARIABLE: EGIT_COMMIT

96 # @ECLASS-VARIABLE: EGIT_REPACK
97 # @DEFAULT_UNSET
98 # @DESCRIPTION:
99 # If non-empty this variable specifies that repository will be repacked to
100 # save space. However this can take a REALLY LONG time with VERY big
101 # repositories.
102
103 # @ECLASS-VARIABLE: EGIT_PRUNE
104 # @DEFAULT_UNSET
105 # @DESCRIPTION:
106 # If non-empty this variable enables pruning all loose objects on each fetch.
107 # This is useful if upstream rewinds and rebases branches often.
108
109 # @ECLASS-VARIABLE: EGIT_NONBARE
110 # @DEFAULT_UNSET
111 # @DESCRIPTION:
112 # If non-empty this variable specifies that all checkouts will be done using
113 # non bare repositories. This is useful if you can't operate with bare
