# Config
|
|
|
|
- python script as config
|
|
- imports PFERD as library
|
|
- operates relative to its own path
|
|
|
|
## Example folder structure
|
|
|
|
```
|
|
.../
|
|
Vorlesungen/
|
|
PFERD/ as symlink, locally or in python's import path
|
|
PFERDconf.py does things relative to its own location (hopefully)
|
|
GBI/ folder to synchronize files into
|
|
...
|
|
Prog/ folder to synchronize files into
|
|
...
|
|
```
|
|
|
|
## Example config
|
|
|
|
```python
|
|
import PFERD
|
|
|
|
def gbi_filter(ilias_path):
|
|
... # rename and move files, or filter them
|
|
return local_path # or None if file should be ignored
|
|
|
|
kit = PFERD.KIT()
|
|
kit.synchronize("crs_855240", "GBI", filter=gbi_filter)
|
|
kit.synchronize("crs_851237", "Prog") # default filter preserves paths
|
|
```
|
|
|
|
# Structure
|
|
|
|
## Things that need to be done
|
|
|
|
- figure out where config file is located
|
|
- get and store shibboleth session cookie
|
|
- get and store ilias session cookie
|
|
- download specific ilias urls (mostly goto.php, probably)
|
|
- parse web page
|
|
- determine if logging in is necessary
|
|
- authenticate if necessary
|
|
- don't re-login if shibboleth session cookie is still valid
|
|
- find folders in current folder
|
|
- find files to download in current folder
|
|
- ignore LA1 test thingy
|
|
- crawl folders and create directory-like structure/file paths
|
|
- use filter function for paths
|
|
- download files to local file paths
|
|
- create folders as necessary
|
|
- remember downloaded files
|
|
- find files that were not previously downloaded
|
|
- remove un-downloaded files
|
|
- remove unnecessary folders (prompt user before deleting!)
|
|
- logging
|
|
- display crawl progress
|
|
- display structure of found files using neat box drawing characters
|
|
- display download progress
|
|
|
|
## How those things are usually done
|
|
|
|
Step 3. to 5. are run for each synchronize() call.
|
|
|
|
1. launch script
|
|
- load cookie files
|
|
2. authenticate
|
|
(assuming enough time has passed for the session cookies to become invalid)
|
|
- prompt user for username
|
|
- prompt user for password (no echo)
|
|
- somehow obtain valid session cookies
|
|
3. crawl
|
|
- start at the id specified in synchronize() args
|
|
- search for folders and files to download
|
|
- build directory structure
|
|
4. download
|
|
- run each path through filter function
|
|
- if file was not filtered:
|
|
- download file and save result to filtered path
|
|
- use sync directory specified in synchronize() args
|
|
- remember the filtered path for later
|
|
5. cleanup
|
|
- search sync directory for files
|
|
- for each file not previously downloaded:
|
|
- prompt user if they want to delete the file (default: No)
|
|
- delete file if user answered Yes
