ILRepack is meant at replacing ILMerge / Mono.Merge.
The former being closed-source, impossible to customize, slow, resource consuming and many more. The later being deprecated, unsupported, and based on an old version of Mono.Cecil.
Here we're using latest (slightly modified) Cecil sources (0.9), you can find the fork here. Mono.Posix is also required (build only, it gets merged afterwards) for executable bit set on target file.
You can grab it using NuGet.
Or if you're old-school (and want to stay like that), this direct link will give you the latest nupkg file, which you can open as a zip file.
A console application has been released (can be used as DLL as well), using same syntax as ILMerge:
Syntax: ILRepack.exe [options] /out:<path> <path_to_primary> [<other_assemblies> ...]
- /help displays this usage
- /keyfile:<path> specifies a keyfile to sign the output assembly
- /log:<logfile> enable logging (to a file, if given) (default is disabled)
- /ver:M.X.Y.Z target assembly version
- /union merges types with identical names into one
- /ndebug disables symbol file generation
- /copyattrs copy assembly attributes (by default only the primary assembly attributes are copied)
- /attr:<path> take assembly attributes from the given assembly file
- /allowMultiple when copyattrs is specified, allows multiple attributes (if type allows)
- /target:kind specify target assembly kind (library, exe, winexe supported, default is same as first assembly)
- /targetplatform:P specify target platform (v1, v1.1, v2, v4 supported)
- /xmldocs merges XML documentation as well
- /lib:<path> adds the path to the search directories for referenced assemblies (can be specified multiple times)
- /internalize sets all types but the ones from the first assembly 'internal'
- /delaysign sets the key, but don't sign the assembly
- /usefullpublickeyforreferences - NOT IMPLEMENTED
- /align - NOT IMPLEMENTED
- /closed - NOT IMPLEMENTED
- /allowdup:Type allows the specified type for being duplicated in input assemblies
- /allowduplicateresources allows to duplicate resources in output assembly (by default they're ignored)
- /zeropekind allows assemblies with Zero PeKind (but obviously only IL will get merged)
- /wildcards allows (and resolves) file wildcards (e.g. `*`.dll) in input assemblies
- /parallel use as many CPUs as possible to merge the assemblies
- /pause pause execution once completed (good for debugging)
- /verbose shows more logs
- /out:<path> target assembly path, symbol/config/doc files will be written here as well
- <path_to_primary> primary assembly, gives the name, version to the merged one
- <other_assemblies> ...
Note: for compatibility purposes, all options can be specified using '/', '-' or '--' prefix.
Builds directly from within VS, or using gradle:
git clone --recursive https://github.com/gluck/il-repack.git
cd il-repack
gradlew.bat msbuild
(Mono.Posix 3.5-compatible dependency was grabbed from a non-standard nuget repo, it has been commited to git to avoid the dependency on this repo)
