The tool

Commands about the tool itself, and the compilers inside it.

miso doctor#

miso doctor

Checks the installation (the package database, base, miso, cpphs, that $MISO_HOME is writable), the tools (cc, curl, tar, sha256sum or shasum; and, as notes, hlint, git and emcc), and in a project, miso.yml, its programs and tests, source dirs, emcc for its browser targets, and its dependencies. It says how to fix each problem, and fails when it found one.

miso upgrade#

miso upgrade [VERSION]

Installs the latest release (or VERSION, e.g. v0.1.0) where this one is installed, by running the installer. The packages projects installed are installed again by their next build.

miso uninstall#

miso uninstall [--yes]

Removes miso: its files in $MISO_HOME (packages, caches, the store) and the tool where the installer put it. It lists what it removes, with sizes, and asks first; --yes does not ask, and is needed when the input is not a terminal. A folder that holds other files keeps them, and a tool installed with nix is never removed. It lists the lines of your shell startup files that add miso to PATH, for you to remove.

miso version#

miso version
miso --version

Prints miso VERSION (MicroHs VERSION).

miso help#

miso help
miso --help

Prints the commands. miso with no arguments, or an unknown command, prints them too.

miso mhs#

miso mhs ARGS...

Runs the MicroHs compiler built into the tool, with the project's .miso/ packages and the tool's as its package path. With a bare -a in ARGS (which clears mhs's package path), miso leaves the package path to ARGS.

miso mcabal#

miso mcabal ARGS...

Runs MicroCabal, which compiles with miso mhs.
