go-autoupdate

Auto update for golang console applications

Basic Example:

myversion := "1.0.0" // for demostration
app_filename := "absolute_executable_filename" 

update := autoupdate.AutoUpdate{Options: autoupdate.Options{
    BaseUrl:  "http://example.com/pub",
    Version:  myversion,
    SelfName: app_filename,
}}

ch := update.InstallUpdate(*v, nil)
result := <-ch
if result != nil {
    panic(result)
    return
}

fmt.Printf("done. %s have been upgraded to version %s\n", filepath.Base(app_filename), v.Version)

version json

Each os/arch update file must have a "version_{os}_{arch}.json" json file inside the baseurl. For instance version_darwin_arm64.json, with this content template:

{
    "version": "1.0.1",
    "datetime": "2022-12-31T15:33:48+0100",
    "checksum": "8b59266eeeb9fd3d1a5272154628f91701dd48a648ae7a725da61da31b45c87b",
    "size": 7776356,
    "path": "./relative/darwin_arm64/target_file.tgz"
}

• checksum is the sha256 checksum of the target_file.tgz
• size is the filesize of the target_file.tgz
• path is the relative path (relative to the baseUrl) of the tgz update file
