DESCRIPTION
Watches an input file and recompiles on changes

OPTIONS

-f, --format <FORMAT>
    The format of the output file, inferred from the extension by default
    Possible values:

    •   pdf

    •   png

    •   svg

    •   html

    •   bundle

--root <DIR>
    Configures the project root (for absolute paths)
    May also be specified with the TYPST_ROOT environment variable.

--input <key=value>
    Add a string key-value pair visible through `sys.inputs`

--font-path <DIR>
    Adds additional directories that are recursively searched for fonts. If multiple paths are specified, they are separated by the system's path separator (`:` on Unix-like systems and `;` on Windows).
    May also be specified with the TYPST_FONT_PATHS environment variable.

--ignore-system-fonts
    Ensures system fonts won't be searched, unless explicitly included via `--font-path`
    May also be specified with the TYPST_IGNORE_SYSTEM_FONTS environment variable.

--ignore-embedded-fonts
    Ensures fonts embedded into Typst won't be considered
    May also be specified with the TYPST_IGNORE_EMBEDDED_FONTS environment variable.

--package-path <DIR>
    Custom path to local packages, defaults to system-dependent location
    May also be specified with the TYPST_PACKAGE_PATH environment variable.

--package-cache-path <DIR>
    Custom path to package cache, defaults to system-dependent location
    May also be specified with the TYPST_PACKAGE_CACHE_PATH environment variable.

--creation-timestamp <UNIX_TIMESTAMP>
    The document's creation date formatted as a UNIX timestamp. For more information, see <https://reproducible-builds.org/specs/source-date-epoch/>.
    May also be specified with the SOURCE_DATE_EPOCH environment variable.

--pretty
    Whether to pretty-print produced output. This formats the output in a more human-readable, but less space-efficient way. Affects HTML, SVG, and PDF export, but not PNG export.

--pages <PAGES>
    Which pages to export. When unspecified, all pages are exported. Pages to export are separated by commas, and can be either simple page numbers (e.g. '2,5' to export only pages 2 and 5) or page ranges (e.g. '2,3-6,8-' to export page 2, pages 3 to 6 (inclusive), page 8 and any pages after it). Page numbers are one-indexed and correspond to physical page numbers in the document (therefore not being affected by the document's page counter).

--pdf-standard <PDF_STANDARD>
    One (or multiple comma-separated) PDF standards that Typst will enforce conformance with
    Possible values:

    •   1.4: PDF 1.4

    •   1.5: PDF 1.5

    •   1.6: PDF 1.6

    •   1.7: PDF 1.7

    •   2.0: PDF 2.0

    •   a-1b: PDF/A-1b

    •   a-1a: PDF/A-1a

    •   a-2b: PDF/A-2b

    •   a-2u: PDF/A-2u

    •   a-2a: PDF/A-2a

    •   a-3b: PDF/A-3b

    •   a-3u: PDF/A-3u

    •   a-3a: PDF/A-3a

    •   a-4: PDF/A-4

    •   a-4f: PDF/A-4f

    •   a-4e: PDF/A-4e

    •   ua-1: PDF/UA-1

--no-pdf-tags
    By default, even when not producing a `PDF/UA-1` document, a tagged PDF document is written to provide a baseline of accessibility. In some circumstances (for example when trying to reduce the size of a document) it can be desirable to disable tagged PDF

--ppi <PPI> [default: 144]
    The PPI (pixels per inch) to use for PNG export

--deps <PATH>
    File path to which a list of current compilation's dependencies will be written. Use `-` to write to stdout

--deps-format <DEPS_FORMAT> [default: json]
    File format to use for dependencies
    Possible values:

    •   json: Encodes as JSON, failing for non-Unicode paths

    •   zero: Separates paths with NULL bytes and can express all paths

    •   make: Emits in Make format, omitting inexpressible paths

-j, --jobs <JOBS>
    Number of parallel jobs spawned during compilation. Defaults to number of CPUs. Setting it to 1 disables parallelism

--features <FEATURES>
    Enables in-development features that may be changed or removed at any time
    Possible values:

    •   html

    •   bundle

    •   a11y-extras
    May also be specified with the TYPST_FEATURES environment variable.

--diagnostic-format <DIAGNOSTIC_FORMAT> [default: human]
    The format to emit diagnostics in
    Possible values:

    •   human

    •   short

--open [<VIEWER>]
    Opens the output file with the default viewer or a specific program after compilation. Ignored if output is stdout

--timings <OUTPUT_JSON>
    Produces performance timings of the compilation process. (experimental) The resulting JSON file can be loaded into a tracing tool such as https://ui.perfetto.dev. It does not contain any sensitive information apart from file names and line numbers.

--no-serve
    Disables the built-in HTTP server for HTML export

--no-reload
    Disables the injected live reload script for HTML export. The HTML that is written to disk isn't affected either way

--port <PORT>
    The port where HTML is served. Defaults to the first free port in the range 3000-3005.

-h, --help
    Print help (see a summary with '-h')

<INPUT>
    Path to input Typst file. Use `-` to read input from stdin

[OUTPUT]
    Path to output file (PDF, PNG, SVG, or HTML). Use `-` to write output to stdout. For output formats emitting one file per page (PNG & SVG), a page number template must be present if the source document renders to multiple pages. Use `{p}` for page numbers, `{0p}` for zero padded page numbers and `{t}` for page count. For example, `page-{0p}-of-{t}.png` creates `page-01-of-10.png`, `page-02-of-10.png`, and so on.
