# ESVN_REPO_URI instead of using -rREV.
ESVN_OPTIONS="${ESVN_OPTIONS:-}"
# @ECLASS-VARIABLE: ESVN_REPO_URI
# @DESCRIPTION:
# repository uri
#
# e.g. http://example.org/trunk, svn://example.org/branch/foo@1234
#
# supported URI schemes:
# http://
# https://
# svn://

#
# to peg to a specific revision, append @REV to the repo's uri
ESVN_REPO_URI="${ESVN_REPO_URI:-}"
# @ECLASS-VARIABLE: ESVN_REVISION
# @DESCRIPTION:
# User configurable revision checkout or update to from the repository
#
# Useful for live svn or trunk svn ebuilds allowing the user to peg
# to a specific revision
#
# Note: This should never be set in an ebuild!

# Password

# project name of your ebuild (= name space)
#
# subversion eclass will check out the subversion repository like:
#
# ${ESVN_STORE_DIR}/${ESVN_PROJECT}/${ESVN_REPO_URI##*/}
#
# so if you define ESVN_REPO_URI as http://svn.collab.net/repo/svn/trunk or
# http://svn.collab.net/repo/svn/trunk/. and PN is subversion-svn.
# it will check out like:
#
# ${ESVN_STORE_DIR}/subversion/trunk
#
# this is not used in order to declare the name of the upstream project.
# so that you can declare this like:
#
# # jakarta commons-loggin

# default: ${PN/-svn}.

# @ECLASS-VARIABLE: ESVN_PATCHES
# @DESCRIPTION:

# you can use regexp in this variable like *.diff or *.patch or etc.
# NOTE: patches will be applied before ESVN_BOOTSTRAP is processed.
#
# Patches are searched both in ${PWD} and ${FILESDIR}, if not found in either
# location, the installation dies.

# Removed in EAPI 6 and later, use PATCHES instead.

# tree by users.
ESVN_OFFLINE="${ESVN_OFFLINE:-${EVCS_OFFLINE}}"
# @ECLASS-VARIABLE: ESVN_UMASK
# @DESCRIPTION:
# Set this variable to a custom umask. This is intended to be set by users.
# By setting this to something like 002, it can make life easier for people
# who do development as non-root (but are in the portage group), and then
# switch over to building with FEATURES=userpriv. Or vice-versa. Shouldn't
# be a security issue here as anyone who has portage group write access
# already can screw the system over in more creative ways.
ESVN_UMASK="${ESVN_UMASK:-${EVCS_UMASK}}"
# @ECLASS-VARIABLE: ESVN_UP_FREQ
# @DESCRIPTION:
# Set the minimum number of hours between svn up'ing in any given svn module. This is particularly
# useful for split KDE ebuilds where we want to ensure that all submodules are compiled for the same
# revision. It should also be kept user overrideable.
ESVN_UP_FREQ="${ESVN_UP_FREQ:=}"
# @ECLASS-VARIABLE: ESCM_LOGDIR
# @DESCRIPTION:
# User configuration variable. If set to a path such as e.g. /var/log/scm any
# package inheriting from subversion.eclass will record svn revision to
# ${CATEGORY}/${PN}.log in that path in pkg_preinst. This is not supposed to be
# set by ebuilds/eclasses. It defaults to empty so users need to opt in.

# Wrapper function to fetch sources from subversion via svn checkout or svn update,
# depending on whether there is an existing working copy in ${ESVN_STORE_DIR}.
#
# Can take two optional parameters:
# repo_uri - a repository URI. default is ESVN_REPO_URI.
# destination - a check out path in S.
