type
SingleValueSetting* {.pure.} = enum ## \
## settings resulting in a single string value
arguments, ## experimental: the arguments passed after '-r'
outFile, ## experimental: the output file
outDir, ## the output directory
nimcacheDir, ## the location of the 'nimcache' directory
projectName, ## the project's name that is being compiled
projectPath, ## experimental: some path to the project that is being compiled
projectFull, ## the full path to the project that is being compiled
command, ## experimental: the command (e.g. 'c', 'cpp', 'doc') passed to
## the Nim compiler
commandLine, ## experimental: the command line passed to Nim
linkOptions, ## additional options passed to the linker
compileOptions, ## additional options passed to the C/C++ compiler
ccompilerPath ## the path to the C/C++ compiler
backend ## the backend (eg: c|cpp|objc|js); both `nim doc --backend:js`
## and `nim js` would imply backend=js
MultipleValueSetting* {.pure.} = enum ## \
## settings resulting in a seq of string values
nimblePaths, ## the nimble path(s)
searchPaths, ## the search path for modules
lazyPaths, ## experimental: even more paths
commandArgs, ## the arguments passed to the Nim compiler
cincludes, ## the #include paths passed to the C/C++ compiler
clibs ## libraries passed to the C/C++ compiler
proc querySetting*(setting: SingleValueSetting): string {.

## Can be used to get a string compile-time option.

## Example:

## .. code-block:: Nim
## const nimcache = querySetting(SingleValueSetting.nimcacheDir)
proc querySettingSeq*(setting: MultipleValueSetting): seq[string] {.
compileTime, noSideEffect.} = discard
## Can be used to get a multi-string compile-time option.
