正则表达式匹配换行符之后的所有内容

Question

我正在尝试编写一个正则表达式来匹配提交散列和与该散列相关联的文件。参见下面的示例文件：

:6585d0f0ba88767ac3b590f719596d864d73e9c1:

harmonicbalance/src/harmonicbalance/HarmonicBalanceFlowModel.cpp
harmonicbalance/src/harmonicbalance/HbFlutterModel.cpp
:8302994b565553c83a048b8905ae597349d99627:

emp/src/emp/PhasePairSingleParticleReynoldsNumber.h
emp/src/emp/TomiyamaDragCoefficientMethod.cpp
:9da194f17ec08bb20ad1be8df68b78ca137ab18a:

combustion/src/combustion/ReactingSpeciesTransportBasedModel.cpp
combustion/src/complexchemistry/TurbulentFlameClosure.cpp
:6a59f0be1e347a65e525e58742bb304639ea9bc4:

meshing/src/meshing/SurfaceMeshManipulation.cpp
physics/src/discretization/FvIndirectRegionInterfaceManager.cpp
physics/src/discretization/FvIndirectRegionInterfaceManager.h
physics/src/discretization/FvRepresentation.cpp
physics/src/discretization/FvRepresentation.h
:64b7f6d36b11b6cd94c20cad53463b7deef8c85a:

resourceclient/src/resourceclient/ResourcePool.cpp
resourceclient/src/resourceclient/ResourcePool.h
resourceclient/src/resourceclient/RestClient.cpp
resourceclient/src/resourceclient/RestClient.h
resourceclient/src/resourceclient/test/ResourcePoolTest.cpp

下面是我想出的正则表达式：

^:([A-Za-z0-9]+):[\n]+([A-Za-z]+\/.*[.a-z])$

此表达式捕获提交散列和第一个文件。

如何捕获所有文件和所有提交？

Answer 1

您可以通过\G使用这个与Java兼容的正则表达式

(?:^:([A-Za-z0-9]+):|(?!^)\G)\n+([A-Za-z/.-]+)

\G在前一个匹配项的末尾或第一个匹配项的字符串开始处断言位置。
