       dune-config - configuring the dune build system




       Unless --no-config or -p is passed, Dune will read a configuration file from the user home
       directory. This file is used to control various aspects of the behavior of Dune.

       The configuration file is normally ~/.config/dune/config on Unix systems and Local
       Settings/dune/config in the User home directory on Windows. However, it is possible to
       specify an alternative configuration file with the --config-file option.

       The first line of the file must be of the form (lang dune X.Y) where X.Y is the version of
       the dune language used in the file.

       The rest of the file must be written in S-expression syntax and be composed of a list of
       stanzas. The following sections describe the stanzas available.


       Syntax: (cache ENABLED)

        This stanza determines whether dune's build caching is enabled. See for details. Valid values for  ENABLED
       are  enabled or  disabled.


       Syntax: (display MODE)

       This stanza controls how Dune reports what it is doing to the user. This parameter can
       also be set from the command line via --display MODE. The following display modes are

           This is the default, Dune shows and update a status line as build goals are being

           Only display errors.

           Print one line per command being executed, with the binary name on the left and the
           reason it is being executed for on the right.

           Print the full command lines of programs being executed by Dune, with some colors to
           help differentiate programs.

       Note that when the selected display mode is progress and the output is not a terminal then
       the quiet mode is selected instead. This rule doesn't apply when running Dune inside
       Emacs. Dune detects whether it is executed from inside Emacs or not by looking at the
       environment variable INSIDE_EMACS that is set by Emacs. If you want the same behavior with
       another editor, you can set this variable. If your editor already sets another variable,
       please open a ticket on the ocaml/dune GitHub project so that we can add support for it.


       Syntax: (jobs NUMBER)

       Set the maximum number of jobs Dune might run in parallel. This can also be set from the
       command line via -j NUMBER.

       The default for this value is 4.


       Syntax: (sandboxing_preference MODE ...)

       Controls the sandboxing mode preference order used by dune. Dune will use the earliest
       item from this list that's allowed by the action dependency specification, or fall back on
       the hard-coded default. See man dune-build for the description of individual modes.
