Field Syntax Reference
======================

Notation
---------------

Field syntax is described as they are in the latest cabal file format version.

* terminals are enclosed in quotes and type set in typewriter script:

  .. math::

      \mathord{"}\mathtt{example}\mathord{"}

* non-terminals are type set in italic:

  .. math::

      \mathit{version\text-range}

* character sets are type set resembling regular expression notation:


  .. math::

      [ \mathord{"}\mathtt{1}\mathord{"} \cdots \mathord{"}\mathtt{9}\mathord{"} ]

  Character set complements have :math:`c` superscript:

  .. math::

      [ \mathord{"}\mathtt{1}\mathord{"} \cdots \mathord{"}\mathtt{9}\mathord{"} ]^c

* repetition is type set using regular expression inspired notation.
  Superscripts tell how many time to repeat:
  The generic notation is :math:`\in[n\ldots5]`, however there
  are common shorthands:
  :math:`\ast` for :math:`\in[0\ldots\infty]` (``many``),
  :math:`+` for :math:`\in[1\ldots\infty]` (``some``),
  :math:`?` for :math:`\in[0\ldots1]` (``optional``).

  Subscripts tell the used separator:

  .. math::

      \mathit{digit}^+_{\mathord{"}\mathtt{.}\mathord{"}}

  Would be ``digit(\.digit)*`` in common regex syntax.

* alternatives are listed in braces separated by vertical bar:

  .. math::

      \{ \mathit{foo} \mid \mathit{bar} \}

  In case of multiple alternatives, the stacked notation is used

  .. math::

      \left\{\begin{gathered}
      \mathit{one} \\
      \mathit{two} \\
      \mathit{three} \\
      \mathit{four} \\
      \mathit{five}
      \end{gathered}\right\}

* parenthesis are used only for grouping:

  .. math::

      \left(\mathit{foo} \mid \mathit{bar}\right)^+

* any amount of spaces, and at least single space are type set using
  :math:`\circ` and :math:`\bullet` respectively.
  They may appear standalone, not only as binary operators.

  .. math::

      \mathit{module} \bullet \mathord{``}\mathtt{as}\mathord{"} \bullet \mathit{module}

* While notation is heavily regular expression inspired, there
  are also fixed points, which allow represent recursive grammars


  .. math::

      \mathbf{fix}\; \mathit{expr}\; \mathbf{in}\; \mathit{digit}
      \mid \mathit{expr} \circ \mathord{``}\mathtt{+}\mathord{"} \circ \mathit{expr}
      \mid \mathord{``}\mathtt{(} \mathord{"} \circ \mathit{expr} \circ \mathord{``}\mathtt{)}\mathord{"}

Lists
-----

Many fields in cabal file format are lists. There are three variations:

Space separated
    Are used for lists of things with simple grammars, for example :pkg-field:`ghc-options`

    .. math::
        {\mathop{\mathit{element}}}^\ast_{\bullet}

Comma separated
    Are used for lists of things with complicated grammars, for example :pkg-field:`build-depends`
    There can be leading or trailing comma (but not both) since ``cabal-version: 2.2``.
    Note, the comma cannot exist alone.

    .. math::
        \mathrm{commalist}(\mathit{element}) =
        \left\{ {\mathop{\mathit{element}}}^\ast_{\left(\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ\right)}\mid\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ{\mathop{\mathit{element}}}^+_{\left(\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ\right)}\mid{\mathop{\mathit{element}}}^+_{\left(\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ\right)}\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}} \right\}

Optional comma separated
    Surprisingly many fields can have optional comma separator.
    Since ``cabal-version: 3.0`` comma usage have to be consistent,
    in other words either used everywhere or nowhere.
    It's recommended to avoid using comma in these fields,
    an example field is :pkg-field:`default-extensions`.

    .. math::
        \mathrm{optcommalist}(\mathit{element}) =
        \left\{ \begin{gathered}{\mathop{\mathit{element}}}^\ast_{\bullet}\\{\mathop{\mathit{element}}}^\ast_{\left(\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ\right)}\\\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ{\mathop{\mathit{element}}}^+_{\left(\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ\right)}\\{\mathop{\mathit{element}}}^+_{\left(\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ\right)}\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\end{gathered} \right\}

Non-terminals
-------------

In the syntax definitions below the following non-terminal symbols are used:

hs-string
    String as in Haskell; it's recommended to avoid using Haskell-specific escapes.

    .. math::
        \mathop{\mathord{``}\mathtt{\text{"}}\mathord{"}}{\left\{ {[\mathop{\mathord{``}\mathtt{\text{"}}\mathord{"}}\mathop{\mathord{``}\mathtt{\text{\\}}\mathord{"}}]^c}\mid\left\{ \begin{gathered}\mathop{\mathord{``}\mathtt{\text{\\}\text{&}}\mathord{"}}\\\mathop{\mathord{``}\mathtt{\text{\\}\text{\\}}\mathord{"}}\\\left\{ \mathop{\mathord{``}\mathtt{\text{\\}n}\mathord{"}}\mid\mathop{\mathit{escapes}} \right\}\\\mathop{\mathord{``}\mathtt{\text{\\}}\mathord{"}}[\mathop{\mathord{``}\mathtt{0}\mathord{"}}\cdots\mathop{\mathord{``}\mathtt{9}\mathord{"}}]\\\mathop{\mathord{``}\mathtt{\text{\\}o}\mathord{"}}[\mathop{\mathord{``}\mathtt{0}\mathord{"}}\cdots\mathop{\mathord{``}\mathtt{7}\mathord{"}}]\\\mathop{\mathord{``}\mathtt{\text{\\}x}\mathord{"}}[\mathop{\mathord{``}\mathtt{0}\mathord{"}}\cdots\mathop{\mathord{``}\mathtt{9}\mathord{"}}\mathop{\mathord{``}\mathtt{A}\mathord{"}}\cdots\mathop{\mathord{``}\mathtt{F}\mathord{"}}\mathop{\mathord{``}\mathtt{a}\mathord{"}}\cdots\mathop{\mathord{``}\mathtt{f}\mathord{"}}]\\\left\{ \mathop{\mathord{``}\mathtt{\text{\\}\text{^}\text{@}}\mathord{"}}\mid\mathop{\mathit{control}} \right\}\\\left\{ \mathop{\mathord{``}\mathtt{\text{\\}NUL}\mathord{"}}\mid\mathop{\mathit{ascii}} \right\}\end{gathered} \right\} \right\}}^\ast_{}\mathop{\mathord{``}\mathtt{\text{"}}\mathord{"}}

unqual-name
    Unqualified component names are used for package names, component names etc. but not flag names. Unqualified component name consist of components separated by dash, each component is non-empty alphanumeric string, with at least one alphabetic character. In other words, component may not look like a number.

    .. math::
        {\left({\mathop{\mathit{alpha\text{-}num}}}^\ast_{}\mathop{\mathit{alpha}}{\mathop{\mathit{alpha\text{-}num}}}^\ast_{}\right)}^+_{\mathop{\mathord{``}\mathtt{\text{-}}\mathord{"}}}

module-name
    Haskell module name as recognized by Cabal parser.

    .. math::
        {\left(\mathop{\mathit{upper}}{\left\{ \mathop{\mathit{alpha\text{-}num}}\mid[\mathop{\mathord{``}\mathtt{\text{'}}\mathord{"}}\mathop{\mathord{``}\mathtt{\text{_}}\mathord{"}}] \right\}}^\ast_{}\right)}^+_{\mathop{\mathord{``}\mathtt{\text{.}}\mathord{"}}}

version
    Version is to first approximation numbers separated by dots, where leading zero is not allowed and each version digit is consists at most of nine characters.

    .. math::
        {\left\{ \mathop{\mathord{``}\mathtt{0}\mathord{"}}\mid[\mathop{\mathord{``}\mathtt{1}\mathord{"}}\cdots\mathop{\mathord{``}\mathtt{9}\mathord{"}}]{[\mathop{\mathord{``}\mathtt{0}\mathord{"}}\cdots\mathop{\mathord{``}\mathtt{9}\mathord{"}}]}^{\in [0\ldots8]}_{} \right\}}^+_{\mathop{\mathord{``}\mathtt{\text{.}}\mathord{"}}}

version-range
    Version range syntax is recursive. Also note the set syntax added in ``cabal-version: 3.0``, set cannot be empty.

    .. math::
        \mathbf{fix}\;\mathop{\mathit{version\text{-}range}}\;\mathbf{in}\;\left\{ \begin{gathered}\mathop{\mathord{``}\mathtt{\text{=}\text{=}}\mathord{"}}\circ\mathop{\mathit{version}}\\\mathop{\mathord{``}\mathtt{\text{>}}\mathord{"}}\circ\mathop{\mathit{version}}\\\mathop{\mathord{``}\mathtt{\text{<}}\mathord{"}}\circ\mathop{\mathit{version}}\\\mathop{\mathord{``}\mathtt{\text{<}\text{=}}\mathord{"}}\circ\mathop{\mathit{version}}\\\mathop{\mathord{``}\mathtt{\text{>}\text{=}}\mathord{"}}\circ\mathop{\mathit{version}}\\\mathop{\mathord{``}\mathtt{\text{^}\text{>}\text{=}}\mathord{"}}\circ\mathop{\mathit{version}}\\\mathop{\mathord{``}\mathtt{\text{=}\text{=}}\mathord{"}}\circ{\left\{ \mathop{\mathord{``}\mathtt{0}\mathord{"}}\mid[\mathop{\mathord{``}\mathtt{1}\mathord{"}}\cdots\mathop{\mathord{``}\mathtt{9}\mathord{"}}]{[\mathop{\mathord{``}\mathtt{0}\mathord{"}}\cdots\mathop{\mathord{``}\mathtt{9}\mathord{"}}]}^{\in [0\ldots8]}_{} \right\}}^+_{\mathop{\mathord{``}\mathtt{\text{.}}\mathord{"}}}\mathop{\mathord{``}\mathtt{\text{.}\text{*}}\mathord{"}}\\\mathop{\mathit{version\text{-}range}}\circ\mathop{\mathord{``}\mathtt{\text{|}\text{|}}\mathord{"}}\circ\mathop{\mathit{version\text{-}range}}\\\mathop{\mathit{version\text{-}range}}\circ\mathop{\mathord{``}\mathtt{\text{&}\text{&}}\mathord{"}}\circ\mathop{\mathit{version\text{-}range}}\\\mathop{\mathord{``}\mathtt{\text{(}}\mathord{"}}\circ\mathop{\mathit{version\text{-}range}}\circ\mathop{\mathord{``}\mathtt{\text{)}}\mathord{"}}\\\mathop{\mathord{``}\mathtt{\text{=}\text{=}}\mathord{"}}\circ\mathop{\mathord{``}\mathtt{\{}\mathord{"}}\circ{\mathop{\mathit{version}}}^+_{\left(\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ\right)}\circ\mathop{\mathord{``}\mathtt{\}}\mathord{"}}\\\mathop{\mathord{``}\mathtt{\text{^}\text{>}\text{=}}\mathord{"}}\circ\mathop{\mathord{``}\mathtt{\{}\mathord{"}}\circ{\mathop{\mathit{version}}}^+_{\left(\circ\mathop{\mathord{``}\mathtt{\text{,}}\mathord{"}}\circ\right)}\circ\mathop{\mathord{``}\mathtt{\}}\mathord{"}}\end{gathered} \right\}
