7z.Libs

📦📦 🗜 nuget.org/packages/7z.Libs

An automated build of the 7z.Libs NuGet packages.

gnt 7z.Libs [?]

Build and use from source:

git clone https://github.com/3F/7z.Libs.git src
cd src
build & cd bin\Release\raw

Note: the build script is configured to use .version by default. Use --target-version to build specific version, e.g.:

build --target-version 24.08

Why 7z.Libs

nuget.org/packages/7z.Libs is available for everyone starting from 2015. It was designed and distributed specially for vsSolutionBuildEvent and for other related purposes.

7z.Libs repository does not include anything from 7-zip (www.7-zip.org) and only represents a fully automated distribution of the 7-zip libraries.

Everything was automated using the following tools:

• vsSolutionBuildEvent
• hMSBuild
• GetNuTool

Preferences

MSBuild Property / Environment variable	native C/C+	.NET	Default value	Description
NG7zLibsCopyToOutput	✔	✔	true	To prevent copying into output path, set as false
NG7zLibsDir32bit	✔	✔	x86	Custom folder name for 32-bit modules if NG7zLibsCopyToOutput=true
NG7zLibsCopyLicense	✔	✔	true	Provide .txt licenses along with modules if NG7zLibsCopyToOutput=true
NG7zLibsResolvePublish	-	✔	true	Resolve the Publish target
NG7zLibsRootPkg	✔	✔	-	Root path to the 7z.Libs package. E.g. path to tools like $(NG7zLibsRootPkg)tools\
NG7zLibsLimitToPlatform	✔	-	legacy	Limit copying x86/x64 modules to specific platform. Values: legacy, true, false
NG7zLibsLimitToPlatform	-	✔	false	Limit copying x86/x64 modules to specific platform. Relies on PlatformTarget

7z.Libs is possible to use in managed projects (.NET, etc.) through Conari engine https://github.com/3F/Conari or SevenZipSharp, and so on.

GetNuTool

GetNuTool simplifies the work at the solution level and more together with .pkg.install feature (see below), for example:

gnt 7z.Libs
gnt 7z.Libs/25.01

Documentation: https://github.com/3F/GetNuTool/?tab=readme-ov-file#tmodes-and-commands

.pkg.install

v1 support in modern 7z.Libs packages compatible with GetNuTool 1.10+

touch mode and use

Syntax: [~] (arch | alias | command) [:filter]

For example,

cmd	Description	Result
gnt ~7z.Libs	All x86 + x64 7z libraries in separate folders	x64 ├─7z.dll ├─7za.dll └─7zxa.dll x86 ├─7z.dll ├─7za.dll └─7zxa.dll
gnt ~7z.Libs -p:use=~	All x86 + x64 7z libraries without subfolder	.\7z.x64.dll .\7z.x86.dll .\7za.x64.dll .\7za.x86.dll .\7zxa.x64.dll .\7zxa.x86.dll
gnt ~7z.Libs -p:use=x64	All x64 libraries in x64 subfolder	x64 ├─7z.dll ├─7za.dll └─7zxa.dll
gnt ~7z.Libs -p:use=~x64	All x64 libraries without subfolders	.\7z.dll .\7za.dll .\7zxa.dll
gnt ~7z.Libs -p:use=~x64:7z	Only x64 7z.dll without subfolder	.\7z.dll
gnt ~7z.Libs -p:use=~:7z or gnt ~7z.Libs -p:use=~7z	7z.dll (x64 and x86) without subfolders	.\7z.x64.dll .\7z.x86.dll
gnt ~7z.Libs -p:use=x32	x32 alias to x86	x32 ├─7z.dll ├─7za.dll └─7zxa.dll
gnt ~7z.Libs -p:use=:7z or gnt ~7z.Libs -p:use=7z	7z.dll (x64 and x86) in separate folders	x64 └─7z.dll x86 └─7z.dll
gnt ~7z.Libs -p:use=~x86:7zxa	Only x86 7zxa.dll without subfolder	.\7zxa.dll

Note: touch mode is applicable only for GetNuTool v1.10 (or newer) and for 7z.Libs packages at least starting with v26.

• if you need support for older packages, please submit a request via issue tracker or you can rebuild any old yourself. For example, using --target-version for old v25.01 will be like:

build --target-version 25.1.0

dotnet's Publish

For dotnet projects 7z.Libs packages supports Publish targets. Both Visual Studio (see Publish... in context menu) and MSBuild, for example:

msbuild -t:Publish

Note NG7zLibsResolvePublish resolves this by default. Set NG7zLibsResolvePublish=false to disable if necessary.

.NET 7-zip

Most progressive use of 7-zip in .NET is possible through Conari

As for project LuNari, it was planned in the past as N7z

However, I have the priority to review this tasks not earlier than after IeXod -> MvsSln projects. Read more about on reddit and Follow the news;
