Adds a quarto preset for .qmd scientific documents rendering to self-contained HTML with SSE live-reload. Uses --embed-resources to avoid a _files directory in the common case. No error_parser since quarto errors are heterogeneous (mixed R/Python/pandoc output).

INTRODUCTION *preview.nvim*
|
|
|
|
preview.nvim is an extensible framework for compiling documents asynchronously
|
|
in Neovim. It provides a unified interface for any compilation workflow —
|
|
LaTeX, Typst, Markdown, or anything else with a CLI compiler.
|
|
|
|
The plugin ships with opt-in presets for common tools (Typst, LaTeX, Pandoc)
|
|
and supports fully custom providers. See |preview.nvim-presets|.
|
|
|
|
==============================================================================
|
|
REQUIREMENTS *preview.nvim-requirements*
|
|
|
|
- Neovim >= 0.11.0
|
|
- A compiler binary for each configured provider (e.g. `typst`, `latexmk`)
|
|
|
|
==============================================================================
|
|
SETUP *preview.nvim-setup*
|
|
|
|
Load preview.nvim with your package manager. For example, with lazy.nvim: >lua
|
|
{
|
|
'barrettruth/preview.nvim',
|
|
}
|
|
<
|
|
Call |preview.setup()| to configure providers before use.
|
|
|
|
==============================================================================
|
|
CONFIGURATION *preview.nvim-configuration*
|
|
|
|
Configure via `require('preview').setup()`.
|
|
|
|
*preview.setup()*
|
|
setup({opts?})
|
|
|
|
`opts` is a table where keys are preset names or filetypes. For each
|
|
key `k` with value `v` (excluding `debug`):
|
|
|
|
- If `k` is a preset name and `v` is `true`, the preset is registered
|
|
as-is under its filetype.
|
|
- If `k` is a preset name and `v` is a table, it is deep-merged with
|
|
the preset and registered under the preset's filetype.
|
|
- If `k` is not a preset name and `v` is a table, it is registered
|
|
directly as a custom provider keyed by filetype `k`.
|
|
- If `v` is `false`, the entry is skipped (no-op).
|
|
|
|
See |preview.nvim-presets| for available preset names.
|
|
|
|
Fields:~
|
|
|
|
`debug` boolean|string Enable debug logging. A string value
|
|
is treated as a log file path.
|
|
Default: `false`
|
|
|
|
*preview.ProviderConfig*
|
|
Provider fields:~
|
|
|
|
`cmd` string[] The compiler command (required).
|
|
|
|
`args` string[]|function Additional arguments. If a function,
|
|
receives a |preview.Context| and returns
|
|
a string[].
|
|
|
|
`cwd` string|function Working directory. If a function,
|
|
receives a |preview.Context|. Default:
|
|
git root or file directory.
|
|
|
|
`env` table Environment variables.
|
|
|
|
`output` string|function Output file path. If a function,
|
|
receives a |preview.Context|.
|
|
|
|
`error_parser` function Receives (output, |preview.Context|)
|
|
and returns vim.Diagnostic[].
|
|
|
|
`errors` false|'diagnostic'|'quickfix'
|
|
How parse errors are reported.
|
|
`false` suppresses error handling.
|
|
`'quickfix'` populates the quickfix
|
|
list and opens it. Default:
|
|
`'diagnostic'`.
|
|
|
|
`clean` string[]|function Command to remove build artifacts.
|
|
If a function, receives a
|
|
|preview.Context|.
|
|
|
|
`open` boolean|string[] Open the output file after the first
|
|
successful compilation. `true` uses
|
|
|vim.ui.open()|. A string[] is run as
|
|
a command with the output path appended.
|
|
|
|
`reload` boolean|string[]|function
|
|
Reload the output after recompilation.
|
|
`true` uses a built-in SSE server for
|
|
HTML files. A string[] is run as a
|
|
command. If a function, receives a
|
|
|preview.Context| and returns a
|
|
string[].
|
|
|
|
*preview.Context*
|
|
Context fields:~
|
|
|
|
`bufnr` integer Buffer number.
|
|
`file` string Absolute file path.
|
|
`root` string Project root (git root or file directory).
|
|
`ft` string Filetype.
|
|
`output` string? Resolved output file path (set after `output`
|
|
is evaluated, available to `args` functions).
|
|
|
|
Example enabling presets:~
|
|
>lua
|
|
require('preview').setup({ typst = true, latex = true, github = true })
|
|
<
|
|
|
|
Example overriding a preset field:~
|
|
>lua
|
|
require('preview').setup({
|
|
typst = { open = { 'sioyek', '--new-instance' } },
|
|
})
|
|
<
|
|
|
|
Example overriding the output path (e.g. latexmk `$out_dir`):~
|
|
>lua
|
|
require('preview').setup({
|
|
latex = {
|
|
output = function(ctx)
|
|
return 'build/' .. vim.fn.fnamemodify(ctx.file, ':t:r') .. '.pdf'
|
|
end,
|
|
},
|
|
})
|
|
<
|
|
|
|
Example with a fully custom provider (key is not a preset name):~
|
|
>lua
|
|
require('preview').setup({
|
|
rst = {
|
|
cmd = { 'rst2html' },
|
|
args = function(ctx)
|
|
return { ctx.file }
|
|
end,
|
|
output = function(ctx)
|
|
return ctx.file:gsub('%.rst$', '.html')
|
|
end,
|
|
},
|
|
})

PRESETS *preview.nvim-presets*
|
|
|
|
preview.nvim ships with pre-built provider configurations for common tools.
|
|
Import them from `preview.presets`:
|
|
|
|
`presets.typst` typst compile → PDF
|
|
`presets.latex` latexmk -pdf → PDF (with clean support)
|
|
`presets.pdflatex` pdflatex → PDF (single pass, no latexmk)
|
|
`presets.tectonic` tectonic → PDF (Rust-based LaTeX engine)
|
|
`presets.markdown` pandoc → HTML (standalone, embedded)
|
|
`presets.github` pandoc → HTML (GitHub-styled, `-f gfm` input)
|
|
`presets.asciidoctor` asciidoctor → HTML (AsciiDoc with SSE reload)
|
|
`presets.quarto` quarto render → HTML (scientific publishing)
|
|
|
|
Enable presets with `preset_name = true`:
|
|
>lua
|
|
require('preview').setup({ typst = true, latex = true, github = true })
|
|
<
|
|
|
|
Override individual fields by passing a table instead of `true`:
|
|
>lua
|
|
require('preview').setup({
|
|
typst = { env = { TYPST_FONT_PATHS = '/usr/share/fonts' } },
|
|
})
