Sending images package to app - buuuudzik - 08.06.2018
Hello,
could you add some example how i can integrate in custom app importing and exporting a package with images?
I know how to upload and download file(there is such example on this forum) so it is more about dealing with files on LM (read/create .zip, saving multiple files)

There are no built-in functions for handling archives. You have to use shell commands via os.execute to create/read archives.
You can also try doing this in browser via JSZip: https://stuk.github.io/jszip/

Im getting a bunch (2~10) of (Small 0.1~2Kb) .xml files sent to a SpaceLynk via FTP. Unfortunately they are arriving all lumped into a zip file. Is there an example for the os.execute zip open command to open it?.
I'm pretty confident of being able to deal with the .xml files once I have them. :-)

Use this example to extract files from zip and read them:
Code:
zip = '/home/ftp/files.zip' -- source zip archive
if not io.exists(zip) then
alert('file not found')
return
end
dir = '/tmp/zip'
os.execute('rm -rf ' .. dir) -- clean-up
os.execute('mkdir ' .. dir) -- create dir
os.execute('unzip -qq -j "' .. zip .. '" -d ' .. dir) -- unzip
files = io.ls(dir) -- list file
for _, file in ipairs(files) do
data = io.readfile(dir .. '/' .. file)
log(file, data)
end
os.execute('rm -rf ' .. dir) -- clean-up
