# Checks parser
checks parser is a program that help parsing different checks to csv.

!!!CURRENTLY SUPPORTED ONLY RUSSIAN CHECKS!!!
To know why, see [this section](#Checks-from-different-countries)

# Usage
### Input
Ways you can input a check to this programm:
* Via image (it uses OCR(Optical Character Recognition) to parse check content. The picture of a check must be contrast and well-lined (text must be perpendicular to right and left borders of an image) enough in order to be parsed well.)
* Via plaintext, copied from an E-Mail. Just copy&paste text from your email, pick a correct store type (autodetect is in my plans!) and parse.
* Via a picture of a check. Be sure to make the image straight and sharp. OCR is not a magic wand :(
* Via QrCode on check (OFD (ОФД, Оператор Фискальных Данных in Russian)).

### Output
At the start of writing this program, I considered 3 or more output formats: csv, xlsx and ods. But throught the development I understood that most of modern table processor (i.e. electronic tables) can import csv much better than I'd be writing a shitty export module, adding more dependencies and shitty code to the codebase. So I decided that there's no need to use anything other than csv format. 

To export, you need to specify an output file path and, if you wish, you can change order and/or rename columns, choose to print or not to print header (column names) and total.

# Installing
## Building
In general, you need to install following dependencies in order to build that app(I suppose you have installed all the build necessaries such as cmake, make, gcc, git, etc...):
* tesseract (you also have to install appropriate for your needs language data)
* opencv
* zbar
* curl
* nlohmann-json
* qt5
* vtk

Please, do not hesitate to open an issue if you cannot build that. I will help and if you are building on a distro that is not listed there, we can append that list as soon as we will solve your problem!
### Linux
##### Arch Linux-based
I recommend using aur helper (I use yay) to install dependencies. Or, if you're masochist, you can build all by yourself /shrug
```
#Install dependencies
yay -S sudo cmake git coreutils base-devel eigen qt5-base mbedtls gtkglext opencv opencv2 zbar nlohmann-json tesseract tesseract-data-rus vtk
#Clone and compile an app
git clone https://git.foxarmy.org/leca/checks-parser
cd checks-parser
cmake .
make -j{nproc}
#If you wish to install that program system-wide, run
sudo make install
```
##### Debian-based
In debian-based distributions most, but not every, package names are the same.

Installation of dependencies for different debian-based distros:
###### Ubuntu 18.04
```apt install -y qtbase5-dev openssl libmbedtls-dev tesseract-ocr tesseract-ocr-rus libopencv-dev libzbar-dev qttools5-dev nlohmann-json-dev libcurl4-openssl-dev libtesseract-dev```
###### Ubuntu 20.04, LMDE (tested only 6), Debian (tested only 12)
```apt install -y qtbase5-dev openssl libmbedtls-dev tesseract-ocr tesseract-ocr-rus libopencv-dev libzbar-dev qttools5-dev nlohmann-json3-dev libcurl4-openssl-dev libtesseract-dev```

Next steps are identical for every debian-based distro
```
#Clone and compile an app
git clone https://git.foxarmy.org/leca/checks-parser
cd checks-parser
cmake .
make -j{nproc}
#If you wish to install that program system-wide, run
sudo make install
```

### Windows 
Maybe
### Mac OS
Probably not, I do not have nor desire or time. But if you can maintain that program on Mac, I'd be grateful! Please, contact me, if you can!

## Precompiled binaries
I plan to make precompiled binaries for Linux and Windows. Maybe I will put it on AUR. I also think that I will be making an AppImage
