pandoc-server(1) Pandoc User's Guide pandoc-server(1) SYNOPSIS pandoc-server [options] DESCRIPTION pandoc-server is a web server that can perform pandoc conversions. It can be used either as a running server or as a CGI program. To use pandoc-server as a CGI program, rename it (or symlink it) as pandoc-server.cgi. (Note: if you symlink it, you may need to adjust your webserver's configuration in order to allow it to follow symlinks for the CGI script.) All pandoc functions are run in the PandocPure monad, which ensures that they can do no I/O operations on the server. This should provide a high degree of security. This security does, however, impose certain limitations: • PDFs cannot be produced. • Filters are not supported. • Resources cannot be fetched via HTTP. • Any images, include files, or other resources needed for the document conversion must be explicitly included in the request, via the files field (see below under API). OPTIONS --port NUM HTTP port on which to run the server. Default: 3030. --timeout SECONDS Timeout in seconds, after which a conversion is killed. De- fault: 2. When pandoc-server is run as a CGI program, this option can be set via the PANDOC_SERVER_TIMEOUT environment variable. --help Print this help. --version Print version. API Root endpoint The root (/) endpoint accepts only POST requests. Response It returns a converted document in one of the following formats (in or- der of preference), depending on the Accept header: • application/octet-stream • text/plain • application/json If the result is a binary format (e.g., epub or docx) and the content is returned as plain text or JSON, the binary will be base64 encoded. If a JSON response is given, it will have one of the following formats. If the conversion is not successful: { "error": string with the error message } If the conversion is successful: { "output": string with textual or base64-encoded binary output, "base64": boolean (true means the "output" is base64-encoded), "messages": array of message objects (see below) } Each element of the "messages" array will have the format { "message": string, "verbosity": string (either "WARNING" or "INFO") } Request The body of the POST request should be a JSON object, with the follow- ing fields. Only the text field is required; all of the others can be omitted for default values. When there are several string alterna- tives, the first one given is the default. text (string) The document to be converted. Note: if the from format is bi- nary (e.g., epub or docx), then text should be a base64 encoding of the document. from (string, default "markdown") The input format, possibly with extensions, just as it is speci- fied on the pandoc command line. to (string, default "html") The output format, possibly with extensions, just as it is spec- ified on the pandoc command line. shift-heading-level-by (integer, default 0) Increase or decrease the level of all headings. indented-code-classes (array of strings) List of classes to be applied to indented Markdown code blocks. default-image-extension (string) Extension to be applied to image sources that lack extensions (e.g. ".jpg"). metadata (JSON map) String-valued metadata. tab-stop (integer, default 4) Tab stop (spaces per tab). track-changes ("accept"|"reject"|"all") Specifies what to do with insertions, deletions, and comments produced by the MS Word "Track Changes" feature. Only affects docx input. abbreviations (file path) List of strings to be regarded as abbreviations when parsing Markdown. See --abbreviations in pandoc(1) for details. standalone (boolean, default false) If true, causes a standalone document to be produced, using the default template or the custom template specified using tem- plate. If false, a fragment will be produced. template (string) String contents of a document template (see Templates in pan- doc(1) for the format). variables (JSON map) Variables to be interpolated in the template. (See Templates in pandoc(1).) dpi (integer, default 96) Dots-per-inch to use for conversions between pixels and other measurements (for image sizes). wrap ("auto"|"preserve"|"none") Text wrapping option: either "auto" (automatic hard-wrapping to fit within a column width), "preserve" (insert newlines where they are present in the source), or "none" (don't insert any un- necessary newlines at all). columns (integer, default 72) Column width (affects text wrapping and calculation of table column widths in plain text formats) table-of-contents (boolean, default false) Include a table of contents (in supported formats). toc-depth (integer, default 3) Depth of sections to include in the table of contents. list-of-figures (boolean, default false) Include a list of figures (in supported formats). list-of-tables (boolean, default false) Include a list of tables (in supported formats). strip-comments (boolean, default false) Causes HTML comments to be stripped in Markdown or Textile source, instead of being passed through to the output format. highlight-style (string, leave unset for no highlighting) Specify the style to use for syntax highlighting of code. Stan- dard styles are "pygments" (the default), "kate", "monochrome", "breezeDark", "espresso", "zenburn", "haddock", and "tango". Alternatively, the path of a .theme with a KDE syntax theme may be used (in this case, the relevant file contents must also be included in files, see below). embed-resources Embed images, scripts, styles and other resources in an HTML document using data URIs. Note that this will not work unless the contents of all external resources are included under files. html-q-tags (boolean, default false) Use <q> elements in HTML instead of literal quotation marks. ascii (boolean, default false) Use entities and escapes when possible to avoid non-ASCII char- acters in the output. reference-links (boolean, default false) Create reference links rather than inline links in Markdown out- put. reference-location ("document"|"section"|"block") Determines whether link references and footnotes are placed at the end of the document, the end of the section, or the end of the block (e.g. paragraph), in certain formats. (See pandoc(1) under --reference-location.) setext-headers (boolean, default false) Use Setext (underlined) headings instead of ATX (#-prefixed) in Markdown output. top-level-division ("default"|"part"|"chapter"|"section") Determines how top-level headings are interpreted in LaTeX, Con- TeXt, DocBook, and TEI. The "default" value tries to choose the best interpretation based on heuristics. number-sections (boolean, default false) Automatically number sections (in supported formats). number-offset (array of integers) Offsets to be added to each component of the section number. For example, [1] will cause the first section to be numbered "2" and the first subsection "2.1"; [0,1] will cause the first sec- tion to be numbered "1" and the first subsection "1.2." html-math-method ("plain"|"webtex"|"gladtex"|"mathml"|"mathjax"|"ka- tex") Determines how math is represented in HTML. listings (boolean, default false) Use the listings package to format code in LaTeX output. incremental (boolean, default false) If true, lists appear incrementally by default in slide shows. slide-level (integer) Heading level that deterimes slide divisions in slide shows. The default is to pick the highest heading level under which there is body text. section-divs (boolean, default false) Arrange the document into a hierarchy of nested sections based on the headings. email-obfuscation ("none"|"references"|"javascript") Determines how email addresses are obfuscated in HTML. identifier-prefix (string) Prefix to be added to all automatically-generated identifiers. title-prefix (string) Prefix to be added to the title in the HTML header. reference-doc (file path) Reference doc to use in creating docx or odt or pptx. See pan- doc(1) under --reference-doc for details. The contents of the file must be included under files. split-level (integer, default 1) Heading level at which documents are split in EPUB or chunked HTML. epub-cover-image (file path) Cover image for EPUB. The contents of the file must be included under files. epub-metadata (file path) Path of file containing Dublin core XML elements to be used for EPUB metadata. The contents of the file must be included under files. epub-subdirectory (string, default "EPUB") Name of content subdirectory in the EPUB container. epub-fonts (array of file paths) Fonts to include in the EPUB. The fonts themselves must be in- cluded in files (see below). ipynb-output ("best"|"all"|"none") Determines how ipynb output cells are treated. all means that all of the data formats included in the original are preserved. none means that the contents of data cells are omitted. best causes pandoc to try to pick the richest data block in each out- put cell that is compatible with the output format. citeproc (boolean, default false) Causes citations to be processed using citeproc. See Citations in pandoc(1) for details. bibliography (array of file paths) Files containing bibliographic data. The contents of the files must be included in files. csl (file path) CSL style file. The contents of the file must be included in files. cite-method ("citeproc"|"natbib"|"biblatex") Determines how citations are formatted in LaTeX output. files (JSON mapping of file paths to base64-encoded strings) Any files needed for the conversion, including images referred to in the document source, should be included here. Binary data must be base64-encoded. Textual data may be left as it is, un- less it is also valid base 64 data, in which case it will be in- terpreted that way. /batch endpoint The /batch endpoint behaves like the root endpoint, except for these two points: • It accepts a JSON array, each element of which is a JSON object like the one expected by the root endpoint. • It returns a JSON array of JSON results. This endpoint can be used to convert a sequence of small snippets in one request. /version endpoint The /version endpoint accepts a GET request and returns the pandoc ver- sion as a plain or JSON-encoded string, depending on Accept headers. /babelmark endpoint The /babelmark endpoint accepts a GET request with the following query parameters: • text (required string) • from (optional string, default is "markdown") • to (optional string, default is "html") • standalone (optional boolean, default is false) It returns a JSON object with fields html and version. This endpoint is designed to support the Babelmark website. AUTHORS Copyright 2022 John MacFarlane (jgm@berkeley.edu). Released under the GPL, version 2 or greater.
