## Installation
* Clone this git repository where you want : `git clone https://github.com/Phyks/BMC`
* Install `requesocks` and `isbntools` _via_ Pypi
* Install `requesocks`, `PyPDF2` and `isbntools` _via_ Pypi
* Install `pdftotext` (provided by Xpdf) and `djvulibre` _via_ your package manager the way you want
* Copy `params.py.example` to `params.py` and customize it to fit your needs

### Data storage
All your documents will be stored in the papers dir specified in `params.py`. All the bibtex entries will be added to the `index.bib` file. You should **not** add entries to this file (but you can edit existing entries without any problem), as this will break synchronization between documents in papers dir and the index. If you do so, you can rebuild the index fie with `./main.py rebuild`.

A list of ideas and TODO. Don't hesitate to give feedback on the ones you really want or to propose your owns.
* if doi does not exist ?
* download djvu
* test file field for bibtex
* Open
* Confirmation for deletion
* Rebuild
* Remove the watermarks on pdf files : First page of IOP publishing articles => tearpages
* Webserver interface
* Various re.compile ?
* check output of subprocesses before it ends
* Split main.py
* Categories
* Edit an entry instead of deleting it and adding it again
## Issues ?
See upstream
* homogeneize\_latex\_encoding => to implement again, bug with metadata upstream
* Remove the watermarks on pdf files => done, some warning in okular on generated pdf, but seems ok. Seems to be a bug in PyPDF2.
