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:useGnuReadline
|
|
Includes the `rdstdin module <rdstdin.html>`_ for `interactive
|
|
mode <nimc.html#nim-interactive-mode>`_ (aka ``nim i``).
|
|
This is not needed on Windows. On other platforms this may
|
|
incorporate the GNU readline library.
|
|
-d:nativeStacktrace
|
|
Use native stack traces (only for Mac OS X or Linux).
|
|
-d:avoidTimeMachine
|
|
Only for Mac OS X, activating this switch will force excluding
|
|
the generated ``nimcache`` directories from Time Machine backups.
|
|
By default ``nimcache`` directories will be included in backups,
|
|
and just for the Nim compiler itself it means backing up 20MB
|
|
of generated files each time you update the compiler. Using this
|
|
option will make the compiler invoke the `tmutil
|
|
<https://developer.apple.com/library/mac/documentation/Darwin/Reference/Manpages/man8/tmutil.8.html>`_
|
|
command on all ``nimcache`` directories, setting their backup
|
|
exclusion bit.
|
|
|
|
You can use the following command to locate all ``nimcache``
|
|
directories and check their backup exclusion bit::
|
|
|
|
$ find . -type d -name nimcache -exec tmutil isexcluded \{\} \;
|
|
--gc:refc|v2|markAndSweep|boehm|go|none
|
|
Selects which garbage collection strategy to use for the compiler
|
|
and generated code. See the `Nim's Garbage Collector <gc.html>`_
|
|
documentation for more information.
|
|
|
|
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`_.
|
|
|
|
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`_.
|
|
|
|
test command
|
|
------------
|
|
|
|
The `test`:idx: command can also be invoked with the alias ``tests``. This
|
|
command will compile and run ``tests/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``).
|
|
|
|
zip command
|
|
-----------
|
|
|
|
The `zip`:idx: command builds the installation ZIP package.
