* fix(compiler): guard active entry before clearing in process callback Problem: when M.compile() is called while a previous process is still running, the old process's vim.schedule_wrap callback unconditionally sets active[bufnr] = nil, wiping the new process from the tracking table. status() incorrectly returns idle and stop() becomes a no-op against the still-running process. Solution: capture obj as an upvalue in each callback and only clear active[bufnr] if it still points to the same process object. * fix(compiler): hoist obj declaration before vim.system closure Problem: lua-language-server flagged obj as an undefined global in both vim.schedule_wrap callbacks because local obj = vim.system(...) puts the variable out of scope inside the closure at declaration time. At runtime the guard active[bufnr].obj == obj evaluated obj as nil, so the clear was always skipped and the process remained tracked indefinitely. Solution: split into local obj / obj = vim.system(...) so the upvalue is in scope when the closure is defined. |

- 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' } },
})
