Introduction
============

The `koch`:idx: program is Nim's maintenance script. It is a replacement
for make and shell scripting with the advantage that it is much more portable.
The word *koch* means *cook* in German. ``koch`` is used mainly to build the
Nim compiler, but it can also be used for other tasks. This document
describes the supported commands and their options.


Commands
========

boot command
------------

The `boot`:idx: command bootstraps the compiler, and it accepts different
options:

-d:release
  By default a debug version is created, passing this option will
  force a release build, which is much faster and should be preferred
  unless you are debugging the compiler.
-d:nimUseLinenoise
  Use the linenoise library for interactive mode (not needed on Windows).

After compilation is finished you will hopefully end up with the nim
compiler in the ``bin`` directory. You can add Nim's ``bin`` directory to
your ``$PATH`` or use the install command to place it where it will be
found.

csource command
---------------

The `csource`:idx: command builds the C sources for installation. It accepts
the same options as you would pass to the `boot command
<#commands-boot-command>`_.

temp command
------------

The temp command builds the Nim compiler but with a different final name
(``nim_temp``), so it doesn't overwrite your normal compiler. You can use
this command to test different options, the same you would issue for the `boot
command <#commands-boot-command>`_.

test command
------------

The `test`:idx: command can also be invoked with the alias ``tests``. This
command will compile and run ``testament/tester.nim``, which is the main
driver of Nim's test suite. You can pass options to the ``test`` command,
they will be forwarded to the tester. See its source code for available
options.

web command
-----------

The `web`:idx: command converts the documentation in the ``doc`` directory
from rst to HTML. It also repeats the same operation but places the result in
the ``web/upload`` which can be used to update the website at
https://nim-lang.org.

By default the documentation will be built in parallel using the number of
available CPU cores. If any documentation build sub commands fail, they will
be rerun in serial fashion so that meaninful error output can be gathered for
inspection. The ``--parallelBuild:n`` switch or configuration option can be
used to force a specific number of parallel jobs or run everything serially
from the start (``n == 1``).
