+
+Author: Barrett Ruth

+
+==============================================================================
+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,
+AsciiDoc, Quarto) 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 in toggle/watch
+ mode. `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 })

+>lua
+ require('preview').setup({

+
+==============================================================================
+PRESETS *preview.nvim-presets*
+
+preview.nvim ships with pre-built provider configurations for common tools.
+Import them from `preview.presets`:

-
-Install with lazy.nvim: >lua

-<
-
-No `setup()` call is needed. The plugin loads automatically when
-|vim.g.preview| is set. See |preview-config|.
-
-==============================================================================
-CONFIGURATION *preview-config*
-
-Configure by setting |vim.g.preview| to 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-presets| for available preset names.
-
- *preview.ProviderConfig*
-Provider fields: ~
-
- {cmd} (string[]) 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 in toggle/watch
- mode. `true` uses |vim.ui.open()|. A
- string[] is run as a command with the
- output path appended. When a string[]
- is used the viewer process is tracked
- and sent SIGTERM when the buffer is
- deleted. `true` and single-instance
- apps (e.g. Chrome) do not support
- auto-close.
-
- {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[].
-
- {detach} (boolean) When `true`, the viewer process opened
- via a string[] `open` command is not
- sent SIGTERM when the buffer is
- deleted. Has no effect when `open` is
- `true`. Default: `false`.
-
- *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).
-
-Global options: ~
-
- {debug} (boolean|string) Enable debug logging. A string value is treated
- as a log file path. Default: `false`.
