|
**Universal document previewer for Neovim**
|
|
|
|
An extensible framework for compiling documents (LaTeX, Typst, Markdown, etc.)
|
|
asynchronously with error diagnostics.
|
|

|
## Features

|
|
|
- Async compilation via `vim.system()`
|
|
- Built-in presets for Typst, LaTeX (latexmk, pdflatex, tectonic), Markdown, GitHub-flavored Markdown, AsciiDoc, and Quarto
|
|
- Compiler errors as native `vim.diagnostic`
|
|
- User events for extensibility (`PreviewCompileStarted`,
|
|
`PreviewCompileSuccess`, `PreviewCompileFailed`)
|
|
|
|

## FAQ
|
|
|
|
**Q: How do I define a custom provider?**
|
|
|
|
```lua
|
|
require('preview').setup({
|
|
rst = {
|
|
cmd = { 'rst2html' },
|
|
args = function(ctx)
|
|
return { ctx.file, ctx.output }
|
|
end,
|
|
output = function(ctx)
|
|
return ctx.file:gsub('%.rst$', '.html')
|
|
end,
|
|
},
|
|
})
|
|
```
|
|
|
|
**Q: How do I override a preset?**
|
|
|
|
```lua
|
|
require('preview').setup({
|
|
typst = { env = { TYPST_FONT_PATHS = '/usr/share/fonts' } },
|
|
})
|
|
```
|
|
|
|
**Q: How do I automatically open the output file?**
|
|
|
|
Set `open = true` on your provider (all built-in presets have this enabled) to
|
|
open the output with `vim.ui.open()` after the first successful compilation in
|
|
toggle/watch mode. For a specific application, pass a command table:
|
|
|
|
```lua
|
|
require('preview').setup({
|
|
typst = { open = { 'sioyek', '--new-instance' } },
|
|
})
|
|
```
