| Maintenance program for Nim |
| Version $1|
| (c) 2017 Andreas Rumpf |
+-----------------------------------------------------------------+
Build time: $2, $3
Usage:
koch [options] command [options for command]
Options:
--help, -h shows this help and quits
--latest bundle the installers with a bleeding edge Nimble
--stable bundle the installers with a stable Nimble (default)
--nim:path use specified path for nim binary
Possible Commands:
boot [options] bootstraps with given command line options
distrohelper [bindir] helper for distro packagers
tools builds Nim related tools
toolsNoNimble builds Nim related tools (except nimble)
doesn't require network connectivity
nimble builds the Nimble tool
Boot options:
-d:release produce a release version of the compiler
-d:nimUseLinenoise use the linenoise library for interactive mode
`nim secret` (not needed on Windows)
-d:leanCompiler produce a compiler without JS codegen or
documentation generator in order to use less RAM
for bootstrapping
Commands for core developers:
runCI runs continuous integration (CI), eg from travis
docs [options] generates the full documentation
csource -d:release builds the C sources for installation
pdf builds the PDF documentation
zip builds the installation zip package
xz builds the installation tar.xz package
testinstall test tar.xz package; Unix only!
tests [options] run the testsuite (run a subset of tests by
specifying a category, e.g. `tests cat async`)
temp options creates a temporary compiler for testing
pushcsource push generated C sources to its repo
Web options:
--googleAnalytics:UA-... add the given google analytics code to the docs. To
build the official docs, use UA-48159761-1
