Conversion application

The ll-pica convert command is used to generate the linglong.yaml file required by Linglong.

View the help information for the ll-cli convert command:

ll-pica convert --help

Here is the output:

Convert deb to uab

Usage:
  ll-pica convert [flags]

Flags:
  -b, --build            build linglong
  -c, --config string    config file
  -h, --help             help for convert
      --pi string        package id
      --pn string        package name
  -t, --type string      get app type (default "local")
  -w, --workdir string   work directory

Global Flags:
  -V, --verbose   verbose output

Translation: After executing the ll-pica init -w w --pi com.baidu.baidunetdisk --pn com.baidu.baidunetdisk -t repo command

We only need to execute the command ll-pica convert -w w -b to convert the Linglong application. Here, we will use the apt download command to download the deb package named com.baidu.baidunetdisk.

ll-pica convert -c com.baidu.baidunetdisk_4.17.7_amd64.deb -w work -b

TIP

Here, the apt download command is used to download the deb package; however, the process may fail due to the deb package being excessively large or issues with obtaining the link. It is recommended to use the following command instead. If you use the following command directly, there is no need to execute the command ll-pica init -w w --pi com.baidu.baidunetdisk --pn com.baidu.baidunetdisk -t repo.

apt download com.baidu.baidunetdisk

ll-pica convert -c com.baidu.baidunetdisk_4.17.7_amd64.deb -w w -b

• -w working directory。
• -c The configuration method employed here utilizes deb files.
• -b It indicates that a build is required; without adding this parameter, neither building nor exporting the layer file will take place.

The constructed products are as follows:

├── package
│   └── com.baidu.baidunetdisk
│       ├── com.baidu.baidunetdisk_4.17.7.0_x86_64_develop.layer
│       ├── com.baidu.baidunetdisk_4.17.7.0_x86_64_runtime.layer
│       ├── linglong
│       └── linglong.yaml
└── package.yaml

Layer files are divided into two categories: runtime and develop. The runtime includes the application's execution environment, while the develop layer, built upon the runtime, retains the debugging environment.
