Visual Studio Code 编辑 LaTex 入门 （一） 刚装了电脑，这几天一直在整理资料还有倒腾软件。今天打开Word突然觉得它很难用，因为它经常出现格式混乱的情况。这时候脑海里浮出Latex，于是上知乎搜索了一下，发现了VS Code这个软件，第一眼就被软件的高颜值吸引了. Visual Studio Code LaTeX Workshop Extension LaTeX Workshop is an extension for Visual Studio Code, aiming to provide core features for LaTeX typesetting with Visual Studio Code. This project won't be successful without contributions from the community, especially from the. DEPRECATED VSCode-LaTeX README Better LaTeX support is available - Time to Upgrade. I recommend you un-install this extension and use one of the other options such as LaTeX Workshop in it's place. To highlight this to existing users upon activating the extension you will see a. LaTeX Workshop is an extension for Visual Studio Code, aiming to provide all-in-one features and utilities for LaTeX typesetting with Visual Studio Code.

LaTeX is one of those things you are sort of forced to learn when preparing technical documents, especially for academia. It is an old (but highly effective) typesetting system, and it is, at its core, complex as hell to use.

In my day to day I jump between plaforms and operating systems so I always dreamed with a LaTeX editor that rule them all, sadly I had not found such thing (yet) but the closest has been, so far, Visual Studio Code so I took some time to prepare an environment and ensure I can work in the same document in the same way in any platform and, well, document the experience.

Visual Studio Online Editor

First we need to install the fantastic LaTeX Workshop, a Visual Studio Code extension designed to make your life with LaTeX easier (of course you need to have VS Code installed first). Now there is the big question, what about LaTeX? well, we have plenty of options, yes, you need to decide what LaTeX distribution to install and run in each of your operating systems and platforms, this is where I have most of my problems in the past, mostly because I got into a point where my installation was corrupted in macOS and I cannot compile Tex documents. Another problem I would like to avoid is to have global applications in my operating system; for example, I use minted a lot and this requires Pygments to be installed in your system, because this is a Python library I would prefer if it is installed in a virtual environment and all of that… As you see it could be daunting and I wanted to have a single and unique way to do it.

Containers to the rescue

If there were a way to isolate (and distribute) a process from all the rest of your processes… Wait a minute, such thing exists! It is called Docker! What if I use a container with all the dependencies I need to do the typesetting of a document in a container and just use it to compile the document and simple reuse the container all over again!

Visual Studio Code has an extension for this, Remote Containers, I just need to configure it to do what I need and make it work with LaTeX Workshop. This was a lot simpler than I thought but it required a few steps, especially for those that never used the extension before.

First, after installed the mentioned extension, we need to create a folder, .devcontainer in the directory where our document project is located, this directory with its content needs to be version controlled if you want to share your experience, it behaves pretty much like your settings for the project. Inside this directory we have to create a Dockerfile with the instructions to assemble our LaTeX container with our requirements, in my case it is very simple:

Feel free to change it to whatever you want to include in your LaTeX distribution, I prefer not to use texlive-full because, well, it will require to install 2GB of packages and I don’t need them all (yet).

Now that we have the instructions to assemble our container I build it locally to avoid delay when running the whole process:

Feel free to use whatever name you want for your image.

Now we create another file, devcontainer.json with the instructions of how to use a container for our project root:

Visual Studio Latex Compile

The dockerFile and image tell to VSCode to use the image we already built, if this image does not exists it will build it from scratch (and this will probably take some time). We tell it to automatically install the LaTeX Workshop extension in this container (if not, later VSCode will ask us if we want to install it or not) and opening the port 36887 from the container, we need to do this to enable the native preview used by the extension.

And this is all! When we open the directory with our LaTeX project VSCode will just ask us if we want to do this in the container, just follow the prompts and it will be set, our project will be compiled with our container and generate our document, if you need something else installed just do it in the container image instead of your machine.
