      otherwise - otherwise
      返回:
      Doc.Empty when cond is true, otherwise otherwise

      参数:
      defaultDoc - default document
      preferWhenFlattened - document selected when flattened
      返回:
      alternative document

    • column

      @Contract("_ -> new") @NotNull static @NotNull Doc column(@NotNull @NotNull IntFunction<Doc> docBuilder)
      Layout a document depending on which column it starts at. align(Doc) is implemented in terms of column.
      参数:
      docBuilder - document generator when current position provided
      返回:
      column action document

    • nesting

      @Contract("_ -> new") @NotNull static @NotNull Doc nesting(@NotNull @NotNull IntFunction<Doc> docBuilder)
      Layout a document depending on the current 'nest'-ing level. align(Doc) is implemented in terms of nesting.
      参数:
      docBuilder - document generator when current nest level provided
      返回:
      nest level action document

    • pageWidth

      @Contract("_ -> new") @NotNull static @NotNull Doc pageWidth(@NotNull @NotNull IntFunction<Doc> docBuilder)
      Layout a document depending on the page width, if one has been specified.
      参数:
      docBuilder - document generator when page width provided
      返回:
      page width action document

    • nest

      @Contract("_, _ -> new") @NotNull static @NotNull Doc nest(int indent, @NotNull @NotNull Doc doc)
      lays out the document with the current nesting level (indentation of the following lines) increased by . Negative values are allowed, and decrease the nesting level accordingly.
      参数:
      indent - indentation of the following lines
      doc - the document to lay out
      返回:
      indented document

    • align

      @Contract("_ -> new") @NotNull static @NotNull Doc align(@NotNull @NotNull Doc doc)
      align lays out the document with the nesting level set to the current column. It is used for example to implement hang(int, Doc).

      As an example, we will put a document right above another one, regardless of the current nesting level. Without 'align'-ment, the second line is put simply below everything we've had so far,

      If we add an 'align' to the mix, the @'vsep'@'s contents all start in the same column,

      参数:
      doc - document to be aligned
      返回:
      aligned document

    • hang

      @Contract("_, _ -> new") @NotNull static @NotNull Doc hang(int deltaNest, @NotNull @NotNull Doc doc)
      hang lays out the document with a nesting level set to the /current column/ plus . Negative values are allowed, and decrease the nesting level accordingly.

      This differs from nest(int, Doc), which is based on the /current nesting level/ plus indent. When you're not sure, try the more efficient 'nest' first. In our example, this would yield

      参数:
      deltaNest - change of nesting level, relative to the start of the first line
      doc - document to indent
      返回:
      hang-ed document

    • par

      @Contract("_, _ -> new") @NotNull static @NotNull Doc par(int indent, @NotNull @NotNull Doc doc)
      Indents by columns, and then indent the first line again by columns.
      参数:
      indent - the indented nesting level
      doc - document to indent
      返回:
      indented document

    • cblock

      @Contract("_, _, _ -> new") @NotNull static @NotNull Doc cblock(@NotNull @NotNull Doc prefix, int indent, @NotNull @NotNull Doc block)
      Creates a C-style indented block of statements. 
         prefix {
   [indent]block
   }

    • ordinal

      @Contract("_ -> new") @NotNull static @NotNull Doc ordinal(int n)

    • plain

      @Contract("_ -> new") @NotNull static @NotNull Doc plain(String text)
      Plain text document
      参数:
      text - text that may not contain '\n'
      返回:
      text document of the whole text

    • english

      @Contract("_ -> new") @NotNull static @NotNull Doc english(String text)

    • symbol

      @Contract("_ -> new") @NotNull static @NotNull Doc symbol(String text)
      参数:
      text - '\n' not allowed!
      返回:
      special symbol

    • cat

      @Contract("_ -> new") @NotNull static @NotNull Doc cat(@NotNull @NotNull kala.collection.SeqLike<Doc> docs)
      cat tries laying out the documents separated with nothing, and if this does not fit the page, separates them with newlines. This is what differentiates it from 'vcat', which always lays out its contents beneath each other.
      参数:
      docs - documents to concat
      返回:
      cat document

    • cat

      @Contract("_ -> new") @NotNull static @NotNull Doc cat(Doc @NotNull ... docs)
      另请参阅:

    • vcat

      @Contract("_ -> new") @NotNull static @NotNull Doc vcat(Doc @NotNull ... docs)

    • vcatNonEmpty

      @Contract("_ -> new") @NotNull static @NotNull Doc vcatNonEmpty(@NotNull @NotNull kala.collection.SeqLike<Doc> docs)

    • stickySep

      @Contract("_ -> new") @NotNull static @NotNull Doc stickySep(@NotNull @NotNull kala.collection.SeqLike<@NotNull Doc> docs)
      stickySep concatenates all documents horizontally with a space, i.e. it puts a space between all entries.

      stickySep does not introduce line breaks on its own, even when the page is too narrow:

      参数:
      docs - documents to separate
      返回:
      separated documents

    • stickySep

      @Contract("_ -> new") @NotNull static @NotNull Doc stickySep(Doc @NotNull ... docs)

    • sep

      @Contract("_ -> new") @NotNull static @NotNull Doc sep(Doc @NotNull ... docs)
      fillSep concatenates the documents horizontally with a space as long as it fits the page, then inserts a 'line' and continues doing that for all documents in . ('line' means that if 'group'ed, the documents are separated with a 'space' instead of newlines. Use cat(kala.collection.SeqLike<org.aya.pretty.doc.Doc>) if you do not want a 'space'.

      Let's print some words to fill the line:

      参数:
      docs - documents to separate
      返回:
      separated documents
