如何使用stack / cabal顺序构建每个haskell包？

Question

我正在尝试调试一些编译问题，我想知道是否可以使用非交错构建步骤，如此处所示。

$ stack build
string-conv-0.1: configure
string-conv-0.1: build
dotnet-timespan-0.0.1.0: configure
dotnet-timespan-0.0.1.0: build
servant-0.7: configure
string-conv-0.1: copy/register
dotnet-timespan-0.0.1.0: copy/register
servant-0.7: build
control-monad-omega-0.3.1: configure
control-monad-omega-0.3.1: build
swagger2-2.0.1: configure
control-monad-omega-0.3.1: copy/register
swagger2-2.0.1: build
eventstore-0.12.0.0: configure

您可以覆盖用于编译的作业数

stack build --jobs=1

没有它

$ stack build
hnexus-models-0.1.0.0: configure
hnexus-models-0.1.0.0: build
key-doc-schema-0.1.0.0: configure
key-doc-schema-0.1.0.0: build
key-doc-schema-0.1.0.0: copy/register
key-doc-client-0.1.0.0: configure
hnexus-models-0.1.0.0: copy/register
key-doc-client-0.1.0.0: build
hnexus-mschema-0.1.0.0: configure
hnexus-mschema-0.1.0.0: build
...

用它

$ stack build --jobs=1
hnexus-models-0.1.0.0: configure
hnexus-models-0.1.0.0: build
hnexus-models-0.1.0.0: copy/register
hnexus-mschema-0.1.0.0: configure
hnexus-mschema-0.1.0.0: build
hnexus-mschema-0.1.0.0: copy/register
bnexus-mschema-0.1.0.0: configure
bnexus-mschema-0.1.0.0: build
bnexus-mschema-0.1.0.0: copy/register
bnexus-client-0.1.0.0: configure
