* fix(commands): register VimLeavePre to call stop_all Problem: spawned compiler processes and watching autocmds were never cleaned up when Neovim exited, leaving orphaned processes running. Solution: register a VimLeavePre autocmd in commands setup that calls compiler.stop_all(), which kills active processes, unwatches all buffers, and stops the reload server. * fix(compiler): replace BufWipeout with BufUnload Problem: cleanup autocmds used BufWipeout, which only fires for :bwipeout. The common :bdelete path (used by most buffer managers and nvim_buf_delete) fires BufUnload but not BufWipeout, so processes and watches leaked on normal buffer deletion. Solution: switch all three cleanup autocmds from BufWipeout to BufUnload, which fires for both :bdelete and :bwipeout. * fix(init): guard against unnamed buffer in public API Problem: calling compile/toggle/clean/open on an unsaved scratch buffer passed an empty string as ctx.file, producing nonsensical output paths like ".pdf" and silently passing empty strings to compiler binaries. Solution: add an early return with a WARN notification in compile, toggle, clean, and open when the buffer has no file name. * fix(compiler): add fs_stat check to one-shot open path Problem: the long-running process path already guarded opens with vim.uv.fs_stat(), but the one-shot compile path and M.open() did not. Compilation can exit 0 and produce no output, and output files can be externally deleted between compile and open. Solution: add the same fs_stat guard to the one-shot open branch and to M.open() before attempting to launch the viewer. * fix(compiler): check executable before spawning process Problem: if a configured binary was missing or not in PATH, vim.system would fail silently or with a cryptic OS error. The user had no actionable feedback without running :checkhealth. Solution: check vim.fn.executable() at the start of M.compile() and notify with an ERROR-level message pointing to :checkhealth preview if the binary is not found. * fix(compiler): reformat one-shot open condition for line length Problem: the added fs_stat condition exceeded stylua's line length limit on the one-shot open guard. Solution: split the boolean condition across multiple lines to match the project's stylua formatting rules. |

preview.nvim
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' } },
})
