# Panache
A language server for Pandoc, Quarto, and R Markdown.
## Quick start
1. Install the **Panache** extension.
2. Open a regular Markdown (`.md`, Pandoc-style), Quarto (`.qmd`), or R Markdown
(`.Rmd`, `.rmd`) file.
3. The extension starts `panache lsp` automatically.
By default, the extension downloads a platform-specific `panache` binary from
GitHub releases on first use.
## Features
- Starts `panache lsp` automatically when you open supported documents.
- Formats documents using Panache's formatter, including Pandoc-style constructs
such as fenced divs, tables, math, citations, and attributes.
- Surfaces Panache diagnostics and code actions in the editor (including
auto-fixable lint rules such as heading hierarchy).
- Works for regular Markdown (`.md`, Pandoc-style), Quarto (`.qmd`), and R
Markdown (`.Rmd`, `.rmd`).
## Binary Installation
By default, the extension downloads a platform-specific `panache` binary from
GitHub releases and uses that binary for the language server.
When `panache.version` is set to `latest`, the extension automatically skips
component-only tags and selects the most recent stable CLI release that contains
a matching platform asset.
You can also provide your own path to the binary:
```json
{
"panache.downloadBinary": false,
"panache.commandPath": "panache"
}
```
## Common setup examples
Use a local binary and disable downloads:
```json
{
"panache.downloadBinary": false,
"panache.commandPath": "/usr/local/bin/panache"
}
```
Pin to a specific release from a specific repository:
```json
{
"panache.version": "2.20.0",
"panache.githubRepo": "jolars/panache"
}
```
Use `panache.releaseTag` only if you need an exact tag override:
```json
{
"panache.releaseTag": "v2.20.0"
}
```
## Requirements and troubleshooting
- **NixOS**: auto-download is skipped by default unless explicitly configured.
Set `panache.commandPath` to your installed binary.
- **Offline / restricted networks / proxies**: set `panache.downloadBinary` to
`false` and provide `panache.commandPath`.
- If download fails, the extension shows a warning and falls back to
`panache.commandPath`.
- The extension contributes `quarto` (`.qmd`) and `rmarkdown` (`.Rmd`, `.rmd`)
language registrations, so it works even without installing a separate Quarto
extension. If Quarto is also installed, both can coexist.
## Settings
- `panache.downloadBinary`: auto-download Panache binary (default: `true`)
- `panache.version`: version to install (default: `"latest"`)
- `panache.releaseTag`: advanced exact tag override (takes precedence if
explicitly set)
- `panache.githubRepo`: GitHub repo for downloads (default: `"jolars/panache"`)
- `panache.commandPath`: fallback command path
- `panache.serverArgs`: extra args after `panache lsp`
- `panache.serverEnv`: extra environment variables
- `panache.extraPath`: extra PATH entries prepended for the language server
process
- `panache.trace.server`: LSP trace level (`off`, `messages`, `verbose`)
- `panache.experimental.incrementalParsing`: enable experimental incremental
parsing in LSP (default: `false`)
If external tools (for example `air` for R code chunks) work in your terminal
but not inside the editor, set `panache.extraPath` to include their install
directory:
```json
{
"panache.extraPath": ["C:\\Users\\<you>\\.local\\bin"]
}
```
## Security and trust
When `panache.downloadBinary` is enabled, binaries are downloaded from GitHub
releases configured by `panache.githubRepo` and either `panache.version` or
`panache.releaseTag` (if explicitly set).
