10     # The git eclass is written to fetch the software sources from
11     # git repositories like the subversion eclass.
12     #
13     #
14     # Description:
15     # If you use this eclass, the ${S} is ${WORKDIR}/${P}.
16     # It is necessary to define the EGIT_REPO_URI variable at least.

27     DESCRIPTION="Based on the ${ECLASS} eclass"
28    
29    
30     ## -- add git in DEPEND
31     #
32     DEPEND=">=dev-util/git-1.4.0"
33    
34    
35     ## -- EGIT_STORE_DIR: git sources store directory
36     #
37     EGIT_STORE_DIR="${PORTAGE_ACTUAL_DISTDIR-${DISTDIR}}/git-src"
38    
39    
40     ## -- EGIT_FETCH_CMD: git clone command
41     #
42     EGIT_FETCH_CMD="git clone --bare"
43    
44     ## -- EGIT_UPDATE_CMD: git fetch command
45     #
46     EGIT_UPDATE_CMD="git fetch -f -u"
47    
48     ## -- EGIT_DIFFSTAT_CMD: Command to get diffstat output
49     #
50     EGIT_DIFFSTAT_CMD="git diff --stat"
51    
52    
53     ## -- EGIT_OPTIONS:
54     #
55     # the options passed to clone and fetch
56     #
57     : ${EGIT_OPTIONS:=}
58    
59    
60     ## -- EGIT_REPO_URI: repository uri
61     #
62     # e.g. http://foo, git://bar
63     #
64     # supported protocols:
65     # http://
66     # https://
67     # git://
68     # git+ssh://
69     # rsync://
70     # ssh://
71     #
72     : ${EGIT_REPO_URI:=}
73    
74    
75     ## -- EGIT_PROJECT: project name of your ebuild
76     #
77     # git eclass will check out the git repository like:
78     #
79     # ${EGIT_STORE_DIR}/${EGIT_PROJECT}/${EGIT_REPO_URI##*/}
80     #
81     # so if you define EGIT_REPO_URI as http://git.collab.net/repo/git or
82     # http://git.collab.net/repo/git. and PN is subversion-git.
83     # it will check out like:
84     #
85     # ${EGIT_STORE_DIR}/subversion
86     #
87     # default: ${PN/-git}.
88     #
89     : ${EGIT_PROJECT:=${PN/-git}}
90    
91    
92     ## -- EGIT_BOOTSTRAP:
93     #
94     # bootstrap script or command like autogen.sh or etc..
95     #
96     : ${EGIT_BOOTSTRAP:=}
97    
98    
99     ## -- EGIT_PATCHES:
100     #
101     # git eclass can apply pathces in git_bootstrap().
102     # you can use regexp in this valiable like *.diff or *.patch or etc.
103     # NOTE: this patches will apply before eval EGIT_BOOTSTRAP.
104     #
105     # the process of applying the patch is:
106     # 1. just epatch it, if the patch exists in the path.
107     # 2. scan it under FILESDIR and epatch it, if the patch exists in FILESDIR.
108     # 3. die.
109     #
110     : ${EGIT_PATCHES:=}
111    
112    
113     ## -- EGIT_BRANCH:
114     #
115     # git eclass can fetch any branch in git_fetch().
116     # Defaults to 'master'
117     #
118     : ${EGIT_BRANCH:=master}
119    
120    
121     ## -- EGIT_TREE:
122     #
123     # git eclass can checkout any tree.
124     # Defaults to EGIT_BRANCH.

129     ## - EGIT_REPACK:
130     #
131     # git eclass will repack objects to save disk space. However this can take a
132     # long time with VERY big repositories. If this is your case set:
133     # EGIT_REPACK=false
134     #
135     : ${EGIT_REPACK:=false}
136    
137     ## - EGIT_PRUNE:
138     #
139     # git eclass can prune the local clone. This is useful if upstream rewinds and
140     # rebases branches too often. If you don't want this to happen, set:
141     # EGIT_PRUNE=false
