Every program, that create temporary files, must delete own garbage
import os, httpclient
type Download = ref object
status: string
temp: string
done: bool
proc finalizeDownload*[Download](o: Download) =
if not o.done and o.temp.existsFile:
# remove temp file when exception occurs"
o.temp.removeFile
proc downloadFileExt*(url, path: string): Download =
new(result, finalizeDownload)
result.done = false
result.temp = path & ".part"
newHttpClient().downloadFile(url, result.temp)
result.status = "200" # inflexible httpclient
result.temp.moveFile(path)
result.done = true
proc main =
let url = "http://www.some.com/file.mp4";
let dl = downloadFileExt(url, url.extractFilename)
echo "downloaded " & url & " with status " & dl.status
try:
main()
finally:
GC_fullCollect()
Run
