# A library of functions for LF/Jenkins bash scripts. In the general case, these
# functions should only use 'local' variables, and should NOT set
-# shell/environment variables. If you want to make a
-# variable available, provide a function that sets the variable: 'function
-# lf_set_foo() {foo=asdf;}'. Any scripts that need access to the variable can
-# call the 'set' function. This keeps the name-space pollution to a minimum.

-# lf-venv-activate()
+# lf-activate-venv [-p|--python python] [-v|--venv-file] [--no-path]
+# [--system-site-packages] [package]...
#
# SYNOPSIS

#
-# lf-venv-activate python3
+# lf-activate-venv tox tox-pyenv
+# or
+# lf-activate-venv jenkins-job-builder

+#
+# lf-activate-venv --python python3.8 --venv-file /tmp/.myvenv git-review
#
# DESCRIPTION
-# This function will validate existance of 'python' venv. If it exists
-# 'path-to-venv/bin' will be prepended to the PATH.
+# This function will create a new Python Virtual Environment (venv) and
+# install the specified packages in the new venv. The venv will be installed
+# in $lf_venv and by default, the $lf_venv/bin directory will be prepended
+# to the PATH.
+#
+# The 'lf_venv' variable will be set so you can directly execute commands
+# in the venv with: $lf_venv/bin/command. lf-activate-venv() will check for
+# existing file '/tmp/.os_lf_venv' and set 'lf_venv' if the file exists.
+#
+# The function provides a --venv-file path for saving the value of the 'lf_env'
+# that can re-used later. By default '/tmp/.os_lf_venv' venv file is created
+# when the --venv-file option is not specified.
+#
+# Subsequent calls to lf-activate-venv() will re-use the existing venv
+# throught and will NOT overwrite 'lf_venv', if the '/tmp/.os_lf_venv'
+# already exists.
+#
+# If a new venv is required delete the file '/tmp/.os_lf_venv' before
+# calling lf-activate-venv() will create a fresh venv.
+#
+# By default all packages are installed with '--upgrade-strategy eager'.
+# The venv will always contain pip & virtualenv.
+#
+# Some packages have a default version. If one of those packages is specified,
+# the 'version' specifier will be added for the install. If the version is
+# specified on the command line that version will be used.
+# The following packages have default versions:
+# Package Version
+# jenkins-job-builder $JJB_VERSION
+#
+# If the --python flag is specified, the specified python executable will be
+# used to create the venv. The --python option must be in the PATH. The venv
+# will be located in $lf_venv (/tmp/venv-####).
+#
+# If the --no-path flag is specified, $lf_venv/bin will not be prepended to
+# the PATH.
+#
+# If the --system-site-packages flag is specified, the --system-site-packages
+# flag will be passed to the inital 'pip install' (python3* only).
#
# RETURN VALUES
-# None
+# OK: 0
+# Fail: 1

#
# DESCRIPTION
-# This function will create/update a Python Virtual Environment (venv) based
-# on the python specified. The 'python' argument must be in the PATH. The venv
-# will be located in ~/.venv## where ## comes from the 'python' argument.
-# I.E. python3 -> ~/.venv3. The resulting venv will be left 'read-only' to
-# discourage the installation of any other packages (except by
-# lf-venv-create()). By default, only versioned packages will be installed, so
-# any required packages need to be specified. By default the 'pip install
-# --upgrade' will be run multiple times. Sometimes pip needs that to get the
-# versioning correct.
