2. ⭐ Unified Development 🚧 [Local PC / Summit / WAM] (Melodic/Noetic):

🔥 (hot-takes) on [Hardware v2] : A unified multi-platform configuration

UWARL_catkin_ws/src: A single common catkin workspace that can be deployed dynamically across multiple platforms. This repository will track other ROS components as submodules on particular commit hask token (without tracking physical files and changes).

uwarl-robot_configs: An all-star installation toolkit that will configure any hardware automatically with simple bash scripts.

Supported OS: Ubuntu 18.04 and Ubuntu 20.04 (includes auto-install for ROS-Noetic)

Install Git and configure the environment necessary from previous section, and SSH authenticated with Github, see instruction @ 0.2 SSH Keys & Github

Clone configurations:

$ cd ~ && git clone git@github.com:UW-Advanced-Robotics-Lab/uwarl-robot_configs.git

Install the repo with auto-script:
```
$ cd ~ && ./uwarl-robot_configs/scripts/auto-config_UWARL_catkin_ws.zsh
```
📓 this script will install automatically based on the user name (e.g. uwarl-orin) to identify the PC space

🌶️ It will install ROS Noetic for Ubuntu 20.04 automatically if your system does not have yet! It will install peak can for Jetson and adlink It will install libbarrett for Jetson

Build:

# update (pull recursively in a batch) of the entire workspace with all required submodules (as noted in common.sh) from anywhere
$ update_ws
# build ws from anywhere
$ build_ws
# source ws from anywhere
$ source_ws

(*) For hardware platform setup, please refer to [ Waterloo-Steel:Platform-Setup.md ]

2.1 How to commit:

check every status of subdirectories of the Catkin Workspace:
```
$ check_ws_status 
```

commit changes for every sub-directory (submodule)

$ cd uwarl-barrrett-ros-pkg 
$ git status 
$ git commit -a 
$ git push

Once you are satisfied with the current version of the workspace, you may commit this specific combination of submodules

$ cd_ws
$ commit_ws # it will automatically log all the submodule status for this commit, and prompt any residual modifications
$ git push

2.2 How to Add a new modules under workspace/src:

Add module into workspace

$ cd_ws
$ git submodule add git@github.com:UW-Advanced-Robotics-Lab/uwarl-zed_ros_wrapper.git
$ git commit ### commit: [New Submodule] : zed ros wrapper
$ git push

Add module name into uwarl-robot_configs/scripts/common.sh

$ cd_config
$ vim scripts/common.sh
## Ex: add zed ros wrapper to wam module
SUBMODULES_FOR_WAM=(
    "uwarl-barrett-ros-pkg" 
    "uwarl-zed_ros_wrapper" # <----- just added
)

Update workspace and install ros dependencies:
```
$ update_ws
```
Build:
```
$ build_ws
```

2.3 [The Branching Strategy] How to branch for modifications:

[Optional] Make sure the current 'workspace' and 'config' is clean, no local modifications:
```
$ check_ws_status
$ check_config_status
```
[Recommended] Makre sure the current 'workspace' and 'config' is the latest:
```
$ sync_latest
```

Branch out your 'workspace':

# cd:
$ cd_ws

# branching strategy:
# [Main branch:] `waterloo_steel/universal/ros1/main`
# [A common session branch: ]
$ git checkout -b universal/{node}/session-{month}-{year}
# OR:
# [A user defined sub-feature branch, derived from a specific session branch: ]
$ git checkout -b {node}/session-{month}-{year}/{feature}
# OR:
# [A general user defined branch: ]
$ git checkout -b usr/{name}/{node}/{feature}

### NOTE:
# {node}: ros1, ros1/robohub, main, checkpoint, ...
# {feature}: demo, fix, fix-numerical-err, ...

[Optional] Publish your 'workspace':

$ cd_ws
$ git push -u origin {your-branch-name-defined-above}

Branch out your 'config':

$ cd_config
$ git checkout -b {your-branch-name-defined-above}

Targeting your config to the new branch:

$ cd_config scripts
$ vim common.sh

# edit:
2| #################################################################
3| ## USER PARAM: ##
4| export UWARL_catkin_ws_branch="{your-branch-name-defined-above}"

[Optional] Publish your 'config':

$ cd_config
$ git push -u origin {your-branch-name-defined-above}

Branching submodules:

$ cd_ws
$ cd {a-specific-submodule}
# Branching: (if this is a continuous development, major:)
$ git checkout -b usr/{name}/{node}/{feature}
# OR: (if this is a minor feature or fixes, minor:)
$ git checkout -b {your-branch-name-defined-above}

Modify and Publish changes of your submodules:

# Commit:
$ git commit 

# Publish:
$ git push -u origin {...}

Publish All Your Changes as A Checkpoint in Workspace:

$ commit_ws

2.4 Rebasing Branches:

⚠️ It is recommended to rebase your branch to the latest version of your target branch, that you branched off. So we can resolve MERGE CONFLICTS locally, and pick up latest changes.

On your local machine:

Make sure you do not have any changes:

# [1] basic:
$ cd {git-folder}
$ git status

# [2] Workspace with submodules:
$ check_ws_status

# [3] Config:
$ check_config_status

# [4] Folder contains submodules:
$ cd {git-folder}
$ check_status

Check out the main branch:

$ checkout {main}
# Ex:
$ checkout waterloo_steel/universal/ros1/main

Pull the latest:

# dry run:
$ git fetch
# update the local to the latest from the origin (remote):
$ git pull

Checkout the original branch:
```
$ git checkout -
```

Rebase:

# [Opt. 1]: just rebase directly
$ git rebase {main}

# [Opt. 2]: interactive rebase, if you need to squash some of the commits
$ git rebase -i {main}

[* if Merge Conflicts]:
1. You have to resolve it in Editor (VSCode)
2. Once, you are done: $ git rebase --continue
3. Iterating, till completion.

Publish your changes:

$ git push -f # brutal force is needed, as the tree root has been updated

2.5 Merging Your Branch:

Pre-requisite: Rebasing Branches to Main (first) --> 2.4 Rebasing Branches:
On GitHub Interface, Create a [PULL REQUEST], assigning reviewers and tags.
Merge, once review is completed.

3. ROS UWARL_catkin_ws Usage Guide:

3.1 Modifications:

switch workspace : git checkout {branch-name}
add modules: $ git submodule add {git-repo}
remove submodules: $ git submodule deinit {git-repo} and you may need delete the submodules in .gitmodules file
Create a new branch of workspace: git checkout -b universal/{node}/{feature}

3.2 Commit and Push:

Commit all changes under submodules
Make sure you run this: $ ./git-status-all.sh to log all status into git-status-all.log
commit all current workspace changes: $ git add . && git commit -a
Push workspace $ git push or upload a branch $ git push -u {your-branch-name}

3.3 Pull latest repo:

$ cd_ws/src && git status # make sure no local changes
$ update_ws

3.4 Restart over the catkin workspace:

# delete current workspace
$ cd $HOME
$ rm -rf UWARL_catkin_ws 
# reinstall everything and build:
$ cd_config
$ ./scripts/auto-config_UWARL_catkin_ws.zsh
$ build_ws
$ source_ws

4. Tools:

4.1 Remote Desktop Auto-Sleep and Auto-Wake Scheduling:

$ sudo cp ~/uwarl-robot_configs/desktop/suspend_until $HOME
# Takes a 24hour time HH:MM as its argument
# Example:
#
$ suspend_until 9:30
#     suspend_until 18:45
#
# You can create a root cron job that calls this script to execute at a
# specific time in the evening and then awake in the morning:
#
$ sudo crontab -e
#
# Now enter something like to run the suspend script at 23:30:
#
30 23 * * * /home/myhomefolder/suspend_until 07:30

4.2 Remote Desktop without physical monitor (Headless Monitor):

4.2.a X server dummy display config:

$ sudo apt-get install xserver-xorg-video-dummy -y  # best for jetson / desktops
$ sudo cp ~/uwarl-robot_configs/desktop/etc/X11/xorg.conf /etc/X11/xorg.conf

4.2.b Fully Headless (NoMachine):

$ sudo systemctl disable display-manager # [to save computer resources, some applications may require display, then you should not disable it ] : suitable for summit
$ sudo /etc/NX/nxserver --restart

4.2.b Temporary Headless (NoMachine):

$ stop_display    # stop display-manager [to save computer resources, some applications may require display, then you should not disable it ] : suitable for jetson when needed
$ start_display   # start display-manager
