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`:cmd: 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`:cmd:), 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`:option:. 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`:option: 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 meaningful error output can be gathered for inspection. The `--parallelBuild:n`:option: switch or configuration option can be used to force a specific number of parallel jobs or run everything serially from the start (`n == 1`). pdf command ----------- The `pdf`:idx: command builds PDF versions of Nim documentation: Manual, Tutorial and a few other documents. To run it one needs to `install Latex/xelatex"A great chef is an artist that I truly respect" -- Robert Stack.
