示例1: archive
export async function archive(format: string, outFile: string, dirToArchive: string, options: ArchiveOptions = {}): Promise<string> {
const args = compute7zCompressArgs(format, options)
// remove file before - 7z doesn't overwrite file, but update
await unlinkIfExists(outFile)
args.push(outFile, options.withoutDir ? "." : path.basename(dirToArchive))
if (options.excluded != null) {
for (const mask of options.excluded) {
args.push(`-xr!${mask}`)
}
}
try {
await exec(path7za, args, {
cwd: options.withoutDir ? dirToArchive : path.dirname(dirToArchive),
}, debug7z.enabled)
}
catch (e) {
if (e.code === "ENOENT" && !(await exists(dirToArchive))) {
throw new Error(`Cannot create archive: "${dirToArchive}" doesn't exist`)
}
else {
throw e
}
}
return outFile
}示例2: installOrRebuild
