NAME
opam-tools - Install development tools within a local switch
SYNOPSIS
opam-tools [OPTION]...
DESCRIPTION
opam-tools installs a local development environment for an OCaml
project. It first sets up an opam local switch, which is an _opam
directory that contains all the dependencies required to build your
code. Since you also need some development tools for building, testing
and documenting your code, it installs the binaries for those inside
_opam/bin.
The opam package manager automatically adds this to your PATH for most
shells, or else it will be added automatically if you use opam exec --
to run your commands. Thus, the end result of invoking opam-tools is
that all the tools and dependencies will be available locally after
the command completes.
If you ever need to refresh the versions of the tools, just run opam
update to get the latest package descriptions, and opam tools again to
reinstall them.
OPTIONS
-c COMPILER, --compiler=COMPILER
Version of the OCaml compiler to use for this project. If omitted,
this defaults to the most recent version that is compatible with
the packages used by the project.
--help[=FMT] (default=auto)
Show this help in format FMT. The value FMT must be one of `auto',
`pager', `groff' or `plain'. With `auto', the format is `pager` or
`plain' whenever the TERM env var is `dumb' or undefined.
--no-install
When creating a local switch, don't look for any local package
definitions to install. This can be useful when you just want to
get tools installed for a new or work-in-progress project.
--pin-tool=NAME,URL
Override the opam definition of a tool with a custom opam pin.
This will cause the tools switch to receive that pin, so it will
apply to all future projects with the same OCaml version as well.
Format is <toolname>,<url> to specify a pin URL, or simply
<toolname>,--dev to use the latest development version.
--tools=TOOLS
(absent=ocamlformat,merlin,mdx,dune,odoc,ocaml-lsp-server,dune-release,duniverse)
Tools to install within the local switch. These can be any opam
packages, but only the binaries will be copied to the local
switch.
--version
Show version information.
COMMON OPTIONS
--color=WHEN (absent=auto)
Colorize the output. WHEN must be one of `auto', `always' or
`never'.
-q, --quiet
Be quiet. Takes over -v and --verbosity.
-v, --verbose
Increase verbosity. Repeatable, but more than twice does not bring
more.
--verbosity=LEVEL (absent=warning)
Be more or less verbose. LEVEL must be one of `quiet', `error',
`warning', `info' or `debug'. Takes over -v.
