Development environment quickstart guide (Gitpod)#
This quick start guide covers:
using GitPod for your SciPy development environment
creating a personal fork of the SciPy repository on GitHub
a quick tour of Gitpod and VSCode
working on the SciPy documentation in Gitpod
Gitpod is an open-source platform for automated and ready-to-code development environments. It enables developers to describe their dev environment as code and start instant and fresh development environments for each new task directly from your browser. This reduces the need to install local development environments and deal with incompatible dependencies.
Gitpod GitHub integration#
To be able to use Gitpod, you will need to have the Gitpod app installed on your GitHub account, so if you do not have an account yet, you will need to create one first.
Make sure to select All repositories access option to avoid issues with permissions later on. Click on the green Install button
This will install the necessary hooks for the integration.
Forking the SciPy repository#
The best way to work on SciPy as a contributor is by making a fork of the repository first.
Once you have authenticated to Gitpod through GitHub, you can install the Gitpod browser extension which will add a Gitpod button next to the Code button in the repository:
If you install the extension - you can click the Gitpod button to start a new workspace.
Alternatively, if you do not want to install the browser extension you can visit https://gitpod.io/#https://github.com/USERNAME/scipy replacing
USERNAMEwith your GitHub username.
In both cases, this will open a new tab on your web browser and start building your development environment. Please note this can take a few minutes.
Once the build is complete, you will be directed to your workspace, including VSCode and all the dependencies you need to work on SciPy. The first time you start your workspace, you will notice that there might be some actions running. This will ensure that you have a development version of SciPy installed and that the docs are being pre-built for you.
Once the build is complete, you can test the build by entering:
This command make use of Meson, for more details on how this affects your workflow migrating from
distutils check the How to build SciPy with Meson section in the Developer documentation.
If you are a regular VSCode user you can install the Gitpod Remote extension on your local VSCode editor and sync your local editor to the remote Gitpod server. To do this click <kbd> F1 </kbd> and search for Gitpod open on VSCode.
Quick workspace tour#
Gitpod uses VSCode as the editor. If you have not used this editor before, you can check the Getting started VSCode docs to familiarise yourself with it.
Your workspace will look similar to the image below:
By default VSCode initialises with a light theme, you can change to a dark theme by with the keyboard shortcut Cmd-K Cmd-T in Mac or Ctrl-K Ctrl-T in Linux and Windows.
We have marked some important sections in the editor:
Your current Python interpreter - by default, the
scipy-devis marked as
baseon the status bar, but it should be displayed as
scipy-devon your terminal. You do not need to activate the conda environment as this will always be activated for you.
Your current branch is always displayed in the status bar. You can also use this button to change or create branches.
GitHub Pull Requests extension - you can use this to work with Pull Requests from your workspace.
Marketplace extensions - we have added some essential extensions to the SciPy Gitpod. Still, you can also install other extensions or syntax highlighting themes for your user, and these will be preserved for you.
Your workspace directory - by default is
/workspace/scipydo not change this as this is the only directory preserved in Gitpod.
We have also pre-installed a few tools and VSCode extensions to help with the development experience:
The Development workflow section of this documentation contains information regarding the SciPy development workflow. Make sure to check this before working on your contributions.
When using Gitpod, note these main differences with the setup described in Development workflow.
You do not need to configure your git username, and email as this should be done for you as you authenticated through GitHub. You can check the git configuration with the command
git config --listin your terminal.
As you started your workspace from your own SciPy fork, you will by default have both “upstream” and “origin” added as remotes. You can verify this by typing
git remoteon your terminal or by clicking on the branch name on the status bar (see image below).
Rendering the SciPy documentation#
You can find the detailed documentation on how rendering the documentation with Sphinx works in the Rendering Documentation with Sphinx section.
The documentation is pre-built during your workspace initialization. So once this task is completed, you have two main options to render the documentation in Gitpod.
Option 1: Using Liveserve#
View the documentation in
scipy/doc/build/html-scipyorg. You can start with
index.htmland browse, or you can jump straight to the file you’re interested in.
To see the rendered version of a page, you can right-click on the
.htmlfile and click on Open with Live Serve. Alternatively, you can open the file in the editor and click on the Go live button on the status bar.
A simple browser will open to the right-hand side of the editor. We recommend closing it and click on the Open in browser button in the pop-up.
To stop the server click on the Port: 5500 button on the status bar.
Option 2: Using the rst extension#
A quick and easy way to see live changes in a
.rst file as you work on it uses the rst extension with docutils.
This will generate a simple live preview of the document without the
html theme, and some backlinks might not be added correctly. But it is an easy and lightweight way to get instant feedback on your work.
Open any of the source documentation files located in
doc/sourcein the editor.
Open VSCode Command Palette with Cmd-Shift-P in Mac or Ctrl-Shift-P in Linux and Windows. Start typing “restructured” and choose either “Open preview” or “Open preview to the Side”.
As you work on the document, you will see a live rendering of it on the editor.
If you want to see the final output with the
html theme you will need to rebuild the docs with
make html-scipyorg and use Live Serve as described in option 1.
- How long is my Gitpod workspace kept for?
Your stopped workspace will be kept for 14 days and deleted afterwards if you do not use them.
- Can I come back to a previous workspace?
Yes, let’s say you stepped away for a while and you want to carry on working on your SciPy contributions. You need to visit https://gitpod.io/workspaces and click on the workspace you want to spin up again. All your changes will be there as you last left them.
- Can I install additional VSCode extensions?
Absolutely! Any extensions you installed will be installed in your own workspace and preserved.
- I registered on Gitpod but I still cannot see a Gitpod button in my repositories
Head to https://gitpod.io/integrations and make sure you are logged in. Hover over GitHub and click on the three buttons that appear on the right. Click on edit permissions and make sure you have
public_repochecked. Click on Update Permissions and confirm the changes in the GitHub application page.
- How long does my workspace stay active if I’m not using it?
If you keep your workspace open in a browser tab but don’t interact with it, it will shut down after 30 minutes. If you close the browser tab, it will shut down after 3 minutes.
