OpenDirDL
downloads open directories
The basics:
1. Create a database of the directory's files with
> opendirdl digest http://website.com/directory/
2. Enable and disable the files you are interested in with
> opendirdl website.com.db remove_pattern ".*"
> opendirdl website.com.db keep_pattern "Daft%20Punk"
> opendirdl website.com.db remove_pattern "folder\.jpg"
Note the percent-encoded string.
3. Download the enabled files with
> opendirdl website.com.db download
The specifics:
digest:
Recursively fetch directories and build a database of file URLs.
> opendirdl digest http://website.com/directory/ <flags>
> opendirdl digest !clipboard <flags>
flags:
-f | --fullscan:
When included, perform HEAD requests on all files, to know the size of
the entire directory.
-db "x.db" | --databasename "x.db":
Use a custom database filename. By default, databases are named after
the web domain.
download:
Download the files whose URLs are Enabled in the database.
> opendirdl download website.com.db <flags>
flags:
-o "x" | --outputdir "x":
Save the files to a custom directory, "x". By default, files are saved
to a folder named after the web domain.
-ow | --overwrite:
When included, download and overwrite files even if they already exist
in the output directory.
-bps 100 | --bytespersecond 100:
-bps 100k | -bps "100 kb" | -bps 100kib | -bps 1.2m
Ratelimit your download speed. Supports units like "k", "m" according
to `bytestring.parsebytes`.
keep_pattern:
Enable URLs which match a regex pattern. Matches are based on the percent-
encoded strings!
> opendirdl keep_pattern website.com.db ".*"
remove_pattern:
Disable URLs which match a regex pattern. Matches are based on the percent-
encoded strings!
> opendirdl remove_pattern website.com.db ".*"
list_basenames:
List Enabled URLs alphabetized by their base filename. This makes it easier
to find titles of interest in a directory that is very scattered or poorly
organized.
> opendirdl list_basenames website.com.db <flags>
flags:
-o "x.txt" | --outputfile "x.txt":
Output the results to a file instead of stdout. This is useful if the
filenames contain special characters that crash Python, or are so long
that the console becomes unreadable.
list_urls:
List Enabled URLs in alphabetical order. No stylization, just dumped.
> opendirdl list_urls website.com.db <flags>
flags:
-o "x.txt" | --outputfile "x.txt":
Output the results to a file instead of stdout.
measure:
Sum up the filesizes of all Enabled URLs.
> opendirdl measure website.com.db <flags>
flags:
-f | --fullscan:
When included, perform HEAD requests on all files to update their size.
-n | --new_only:
When included, perform HEAD requests only on files that haven't gotten
one yet.
-t 4 | --threads 4:
The number of threads to use for performing requests.
If a file's size is not known by the time this operation completes, you
will receive a printed note.
tree:
Print the file / folder tree.
> opendirdl tree website.com.db <flags>
flags:
-o "x.txt" | --outputfile "x.txt":
Output the results to a file instead of stdout. This is useful if the
filenames contain special characters that crash Python, or are so long
that the console becomes unreadable.
If the filename ends with ".html", the created page will have
collapsible boxes rather than a plaintext diagram.
