* fix(compiler): skip reload command for one-shot builds
Problem: compile() unconditionally resolved the reload command, so
:Preview build on a provider with reload = function/table (e.g. typst)
would start a long-running process (typst watch) instead of a one-shot
compile (typst compile). Error diagnostics were also lost because
typst watch does not exit non-zero on input errors.
Solution: add an opts parameter to compile() with a oneshot flag.
M.build() passes { oneshot = true } so resolve_reload_cmd() is
skipped and the one-shot path is always taken. toggle() continues
to call compile() without the flag, preserving long-running behavior
for watch mode.
* fix(compiler): respect provider open config in M.open()
Problem: :Preview open always called vim.ui.open regardless of the
provider's open field. Providers configured with a custom opener
(e.g. open = { 'sioyek', '--new-instance' }) were ignored, so the
first build opened with sioyek but :Preview open fell back to the
system default.
Solution: init.lua resolves the provider's open config and passes it
to compiler.open(). If open_config is a table, the custom command is
spawned with the output path appended. Otherwise vim.ui.open is used
as before.
* fix: normalize notify prefix to [preview.nvim]: everywhere
Problem: some vim.notify calls used [preview.nvim] (no colon) while
others used [preview.nvim]: — inconsistent with the log module format.
Solution: add the missing colon and space to all notify calls in
init.lua and compiler.lua so every user-facing message matches the
[preview.nvim]: prefix used by the log module.

Async document compilation 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, Markdown, and GitHub-flavored Markdown
- Compiler errors as native
vim.diagnostic - User events for extensibility (
PreviewCompileStarted,PreviewCompileSuccess,PreviewCompileFailed)
Requirements
- Neovim 0.11+
Installation
Install with your package manager of choice or via luarocks:
luarocks install preview.nvim

FAQ
Q: How do I define a custom provider?
require('preview').setup({
typst = {
cmd = { 'typst', 'compile' },
args = function(ctx)
return { ctx.file }
end,
output = function(ctx)
return ctx.file:gsub('%.typ$', '.pdf')
end,
},
})
Q: How do I override a preset?
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. For
a specific application, pass a command table:
require('preview').setup({
typst = { open = { 'sioyek', '--new-instance' } },
})
