# 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.
-
+#
+# This script will be installed in ~jenkins by the Jenkins Init Script when the
+# build agent boots. When the build starts it should already be installed.

# NAME
-# lf-activate-venv [-p|--python python] [package]...
+# lf-activate-venv [-p|--python python] [-v|--venv-file] [--no-path]
+# [--system-site-packages] [package]...
#
# SYNOPSIS
# # shellcheck disable=SC1090
# or
# lf-activate-venv lftools
# or
-# lf-activate-venv --python 3.6 git-review
+# lf-activate-venv --python python3.8 git-review
+#
+# lf-activate-venv --python python3.8 --venv-file /tmp/.myvenv git-review
#
# DESCRIPTION
# This function will create a new Python Virtual Environment (venv) and
-# install the specified packages in the new venv. The bin directory from the
-# venv will be prepended to the PATH.
+# 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.
# Package Version
# jenkins-job-builder $JJB_VERSION
#
-# If the --python option is specified, that python executable will be used to
-# create the venv. The --python option must be in the PATH. The venv will be
-# located in '/tmp/venv-####'.
+# 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
# OK: 0
