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