Nick Vigilante c84aa564ba docs: normalize code-fence languages for Shiki compatibility (#27161)
Normalizes non-standard code-fence language tags across `docs/**` so a
strict highlighter (Shiki, used by Fumadocs) won't fail the build on an
unrecognized language, and unifies redundant synonym tags onto one
canonical form per language. The current renderer (Speed-Highlight)
detects the language from the code content, not the fence label, so this
drift wasn't visible until now.

## Changes

- `hcl` -> `tf` (199 fences, including indented ones nested in
numbered/bulleted lists). Shiki ships `hcl` and `terraform` as two
distinct grammars (not aliases); every `hcl`-tagged fence in `docs/**`
is actually Terraform resource/data/provider syntax, so the more
specific `terraform` grammar is correct for all of them. `tf` is Shiki's
own alias for that grammar, and it's also what GitHub's own markdown
renderer resolves to the same HCL/Terraform highlighting.
- `pwsh`/`powershell` -> `ps1`. Both `ps` and `ps1` are registered
PowerShell aliases in Shiki, but on GitHub's renderer only `.ps1` is a
registered file extension (`.ps` isn't), so `ps1` renders identically to
`powershell` there today while bare `ps` would silently lose
highlighting.
- `env` -> `dotenv` (a dedicated Shiki grammar for `KEY=VALUE` files)
- `text`/`output`/`none`/`url` -> `txt`. Same built-in plain-text
fallback either way, just shorter.
- `Dockerfile` -> `dockerfile` (lowercase)
- `bash`/`shell` -> `sh` (732 fences). Shiki and GitHub both alias all
three to a single shell grammar; this was already the style guide's
stated preference, just not enforced across the existing corpus until
now.
- `markdown` -> `md` (4 fences). Alias of the same grammar in both Shiki
and GitHub.
- `jsonc` -> `json` (1 fence). The block has no comments or trailing
commas, so it doesn't need the comments-capable grammar.
- `ts` -> `tsx` (2 fences, `docs/about/contributing/frontend.md`).
Verified the actual content tokenizes identically under both grammars,
and a sibling block in the same file already needs `tsx` for real JSX,
so unifying to one tag is safe for this file. Documented a caveat: `tsx`
mis-tokenizes the legacy angle-bracket type-assertion syntax
(`<Type>value`), which is invalid in real `.tsx` files anyway, so use
`value as Type` instead.
- `yml` -> `yaml` (1 fence)
- Updated `docs/.style/style-guide/formatting.md` to document all
canonical tags

`promql` (2 fences) and `caddyfile` (2 fences) are left as-is. Shiki
doesn't bundle a grammar for either, so they need a custom grammar
registration when the site adopts Shiki, rather than degrading to `txt`.
Tracked as follow-up work under DOCS-118 and
[DOCS-544](https://linear.app/codercom/issue/DOCS-544/vendor-a-local-promql-grammar-for-shiki-syntax-highlighting)
(promql).

Does not touch `offlinedocs/`.

<details>
<summary>How the fence tags were verified</summary>

Each tag was tested against a real `shiki@latest` highlighter instance
(`codeToHtml`/`codeToTokens`) and cross-checked against GitHub's
`@wooorm/starry-night` grammar sources (the renderer that actually
displays these `.md` files today, in repo browsing and PR diffs), since
that's what determines whether brevity is safe before Shiki adoption:

```text
FAIL  env        -- Language `env` is not included in this bundle.
FAIL  Dockerfile -- Language `Dockerfile` is not included in this bundle.
FAIL  promql     -- Language `promql` is not included in this bundle.
FAIL  caddyfile  -- Language `caddyfile` is not included in this bundle.
FAIL  pwsh       -- Language `pwsh` is not included in this bundle.
FAIL  output     -- Language `output` is not included in this bundle.
```

`hcl` doesn't error in Shiki, since it's a real grammar, but that's
exactly the trap: it was silently rendering every fence with the generic
HCL grammar instead of the Terraform-specific one. Every `hcl`-tagged
fence in `docs/**` was manually checked against `origin/main` and is
genuinely Terraform content.

For `ts`/`tsx`, tokenizing the actual doc content confirmed identical
output under both grammars; a synthetic test with the legacy
angle-bracket cast syntax confirmed `tsx` degrades on that specific
construct, which the style guide now calls out.

The first normalization pass only matched fence tags at column 0
(`^```tag$`), missing tags indented inside numbered/bulleted lists. A
follow-up pass caught the remaining occurrences at any indentation
level.

Microsoft Azure

This guide shows you how to set up the Coder server on Azure which will provision Azure-hosted Linux workspaces.

Requirements

This guide assumes you have full administrator privileges on Azure.

Create An Azure VM

From the Azure Portal, navigate to the Virtual Machines Dashboard. Click Create, and select creating a new Azure Virtual machine .

Azure VM creation page

This will bring you to the Create a virtual machine page. Select the subscription group of your choice, or create one if necessary.

Next, name the VM something relevant to this project using the naming convention of your choice. Change the region to something more appropriate for your current location. For this tutorial, we will use the base selection of the Ubuntu Gen2 Image and keep the rest of the base settings for this image the same.

Azure VM instance details Azure VM size selection

Up next, under Inbound port rules modify the Select inbound ports to also take in HTTPS and HTTP.

Azure VM inbound port rules

The set up for the image is complete at this stage. Click Review and Create - review the information and click Create. A popup will appear asking you to download the key pair for the server. Click Download private key and create resource and place it into a folder of your choice on your local system.

Azure VM key pair generation

Click Return to create a virtual machine. Your VM will start up!

Azure VM deployment complete

Click Go to resource in the virtual machine and copy the public IP address. You will need it to SSH into the virtual machine via your local machine.

Follow these instructions to SSH into the virtual machine. Once on the VM, you can run and install Coder using your method of choice. For the fastest install, we recommend running Coder as a system service.

Install Coder

For this instance, we will run Coder as a system service, however you can run Coder a multitude of different ways. You can learn more about those here.

In the Azure VM instance, run the following command to install Coder

curl -fsSL https://coder.com/install.sh | sh

Run Coder

Run the following command to start Coder as a system level service:

sudo systemctl enable --now coder

The following command will get you information about the Coder launch service

journalctl -u coder.service -b

This will return a series of logs related to running Coder as a system service. Embedded in the logs is the Coder Access URL.

Copy the URL and run the following command to create the first user, either on your local machine or in the instance terminal.

coder login <url***.try.coder.app>

Fill out the prompts. Be sure to save use email and password as these are your admin username and password.

You can now access Coder on your local machine with the relevant ***.try.coder.app URL and logging in with the username and password.

Creating and Uploading Your First Template

First, run coder template init to create your first template. You’ll be given a list of possible templates to use. This tutorial will show you how to set up your Coder instance to create a Linux based machine on Azure.

Coder CLI template init

Press enter to select Develop in Linux on Azure template. This will return the following:

Coder CLI template init

To get started using the Azure template, install the Azure CLI by following the instructions here. Run az login and follow the instructions to configure the Azure command line.

Coder is running as a system service, which creates the system user coder for handling processes. The Coder user will require access to the Azure credentials to initialize the template.

Run the following commands to copy the Azure credentials and give the coder user access to them:

sudo cp -r ~/.azure /home/coder/.azure
sudo chown -R coder:coder /home/coder/.azure/

Navigate to the ./azure-linux folder where you created your template and run the following command to put the template on your Coder instance.

coder templates push

Congrats! You can now navigate to your Coder dashboard and use this Linux on Azure template to create a new workspace!
