Originally a set of CLI python scripts, it is now written in C++ and offers a GUI made using Qt. While a "web app" would have been an option, I prefer a desktop application for something like looqs. I chose Qt because I am more familiar with it than with any other GUI framework. To my knowledge, potential alternatives like GTK do not include as many "batteries" as Qt anyway, so the job presumably would have been harder there.

## Security
The architecture ensures that the parsing of documents and the preview generation is sandboxed by [exile.h](https://github.com/quitesimpleorg/exile.h). looqs uses a multi-process architecture to achieve this.
Qt code is considered trusted in this model. While one may criticize this, it was the only practical solution. looqs uses its serialization mechanism and other classes to communicate between the non-sandboxed GUI process and the sandboxed processes.

want to run some heavy Java based solutions. I explored other options like Postgresql, I've discard them due to some limitations back then.
Down the road, alternatives will be explored of course if sqlite should not suffice anymore.
## File format support
The pdf library is libpoppler. Files such as .odt or .docx documents are opened with libquazip. The XML files in there are not parsed,
looqs simply strips the tags and that seems to work fine so far. Naturally, this is not the "proper way", so there is room for improvement maybe here. However, those file formats are not a huge priority for me personally. libuchardet does encoding detection and conversion.

Naturally looqs won't be able to index and render previews for everything. Such approach would create a huge bloated binary. In the future, there will be some plugin system of some sorts, either we will load .so objects or use subprocesses.
