This repository has a basic Ximera course along with instructions for deploying it, which will help you get started using Ximera. It is designed to assist new users. If there are problems with the instructions below, please submit an issue on the "Issues" tab at ximeraFirstSteps.

The course(s) in this repo are published in the following locations:

• https://ximera.osu.edu/firststeps24/aFirstStepInXimera
• https://set.kuleuven.be/voorkennis/firststeps24/aFirstStepInXimera/basics/basicWorksheet
• https://set.kuleuven.be/voorkennis/firststeps24/variant/aNewlayout/variant/basics/basicWorksheet

If you follow the instructions in this Readme, you can publish the course on your own PC at

• http://localhost:2080/firststeps24 (from within your Codespace)
  or
• http://localhost:2000/firststeps24 (if running on your local PC),

where you will be able to change, test, and fine-tune how your content is deployed online.

Quick Start

This section will help you play around with Ximera, edit your first Ximera course, and publish a test version to your own computer.

Fork the repository

You'll have some difficulty saving your work unless you fork this repository.

Procedure:

• Log into GitHub and go to ximeraFirstSteps
• Push the "Fork" button, and now you have a copy of this repository in your account.
• Start a Codespace (under the green 'Code' button).
• Presumably, GitHub will notify you (somewhat inconspicuously) that you will pay for this codespace. You can ignore this warning, as the first 120 hours per month are free, which is sufficient for experimenting.
• The first time you start this codespace, it will take a few minutes to build a "devcontainer" for you. Subsequent starts will be faster.
• You should get a Visual Studio Code window inside your browser with buttons in the bottom right of the window: 'PDF,' 'HTML,' 'SERVE,' and 'Extra.'
• Push 'SERVE' and wait a few minutes to let your Codespace compile the demo course.
• Select 'PORTS' (next to 'TERMINAL'), and click on the world icon that appears next to the URL under 'Forwarded Address' to open a browser window on your private Ximera server inside your Codespace.

Compare with the published course

Once you've deployed the course, you can compare your local version to ours.

The KU Leuven version also contains two PDF versions: one with answers and one without.

Publishing the course(s) to a public Ximera server (requires a GPG key)

The file scripts/config.txt determines where (and with which version of Ximera) to publish your courses.

Relevant settings:

• XIMERA_URL contains the server URL where you want to publish your repo (http://localhost:2000/ for testing or https://ximera.osu.edu for a live deployment).
• XIMERA_NAME contains the name (lowercase, no underscores!) under which to publish this repo, e.g., XIMERA_NAME=testing would publish to https://ximera.osu.edu/testing.

You can save and commit these settings.

To deploy to a public server (e.g., the OSU server), a (personal) GPG key is needed to ensure that no one overwrites your online course without your knowledge. (If this does happen, you can re-deploy and contact the Ximera developers.)

Publishing online using Codespaces

When using Codespaces, your own GPG key and ID need to be added to Codespaces Secrets as GPG_KEY and GPG_KEY_ID. In GitHub, go to your profile picture, select "Settings," then on the left select "Codespaces," and you should see "Secrets" with a green button labeled "New secret."

If you do not yet have a GPG key (check with gpg --list-keys), you can generate one with

gpg --gen-key

Answer all the questions, but leave the passphrase blank.

Note: On macOS, you might not be able to leave the passphrase blank. In this case, go to https://gpgtools.org/ and install the GPG Suite. This will provide a GUI that will produce a GPG key with spaces. Delete these spaces, and the key (without spaces) is your new key. You may need to quit and reopen your terminal.

Add GPG_KEY_ID=ABCD3562DBF99...29292 as a GitHub secret.

You will also need your private key, which you can show with

gpg --export-secret-key

or, if you have multiple keys:

gpg --export-secret-key ABC...your-key-id...92

This will output something like:

WONTWORKRUdBQR1AFURSBLRVJTigUFJJVkkgQktYVJOcxPQ0sk1CREFEdGU5 
...             ...
... OTHER       ...
... LINES       ...
... IN YOUR     ...
... PRIVATE KEY ... 
...             ...
R1AgUFQkxPQJ0tLQVkFURSBJkgLRV0stLSo=

Add GPG_KEY=sdkjfsdkjfsklj into your GitHub Secrets. Restart your Codespace. If you type

echo $GPG_KEY_ID

it should return your public GPG key. If not, quit the browser and reload.

Debugging

You get an interactive BASH shell inside the Docker container, with your local folder available under /code. You could, for example, use

pdflatex FILE.tex

or

xake -v compile FILE.tex

Deploying from your own computer

To deploy from your own machine, you will need Docker and VS code installed. We will supply further instructions for this soon.

Making New Courses

There are several options to create a new repo with new Ximera courses that will deploy online:

Starting from https://github.com/XimeraProject/ximeraNewProject

Clone this repo, remove extraneous content, change the repo name, and push to your account. Then start adding TeX code.

Starting with an Existing Repository

Follow these steps carefully.

Copy the following files and folders from this repo to your repo:

• .gitignore
• scripts
• .vscode

If a .gitignore file already exists, we suggest you replace it with ours or at least check for differences. Remember, you should never push .ximeraserve. If a .vscode folder exists, compare your files with ours and check for differences.

The .vscode folder is not required, but without it, you won’t have the PDF/HTML/Bake/Serve buttons, and you'll need to run:

• ./scripts/xmlatex compilePdf <path-to-your-texfile>
• ./scripts/xmlatex compile <path-to-your-texfile>
• ./scripts/xmlatex bake
• ./scripts/xmlatex serve

You may need to make xmlatex executable with

chmod +x ./scripts/xmlatex
