🌿 Chlorophyll A and B maintenance

Lab utility for determining the maintenance of chlorophylls A and B in plant material

Run it in interactive mode

chloro

or run it with specified keys

chloro [options] -w <weight> -f <filt> -p <prob> -s <solv> --d665 <value> --d649 <value>

Using -df key you may write data to *.csv file for the next importing to LibreOffice Calc, MS Excell or Google Tables

.sh file example to run in terminal

#!/bin/bash

echo "measurement 1"
chloro -w 1.3 -f 25 -p 3 -s 5 --d665 1.25 --d649 0.45
echo ""

echo "measurement 2"
chloro -w 1 -f 25 -p 3 -s 5 --d665 1.1 --d649 0.41
echo ""

exec $SHELL

.sh file example for writing to .csv

#!/bin/bash

chloro -w 1 -f 25 -p 3 -s 1 --d665 1.256 --d649 0.8 -df
chloro -w 1.5 -f 25 -p 3 -s 1 --d665 1.1 --d649 0.7 -df
chloro -w 1.3 -f 25 -p 3 -s 1 --d665 0.9 --d649 0.6 -df
chloro -w 2 -f 25 -p 3 -s 1 --d665 0.965 --d649 0.65 -df
chloro -w 1.5 -f 25 -p 3 -s 1 --d665 1.025 --d649 0.6 -df
chloro -w 1.5 -f 25 -p 3 -s 1 --d665 0.984 --d649 0.625 -df

🛠 Dependencies

To build the project from source, you will need:

• A compiler with full C++23 support (GCC >= 14, verified with GCC 16)
• CMake (>= 3.31)
• RapidJSON - a fast, header-only JSON parser and generator library
• rpm-build - for Fedora/CentOS Stream

On Fedora based systems run

sudo dnf group install development-tools
sudo dnf install cmake rpm-build rapidjson-devel

On Debian based systems run

sudo apt update
sudo apt install build-essential cmake rapidjson-dev

On other systems see the details of your distro

To compile and run the utility (Fedora/CentOS Stream)

1. Clone the Repository

git clone https://github.com/Evgenk2020/chlorophyll-linux
cd chlorophyll-linux

2. Build the Project with .rpm setup package for Fedora/CentOS Stream by default

./build.sh
cd build

3. Install .rpm package from build folder

sudo dnf install *.rpm

4. Run the application in terminal directly

chloro -h

---

If using either than Fedora/CentOS Stream

1. Clone the Repository

git clone https://github.com/Evgenk2020/chlorophyll-linux
cd chlorophyll-linux

2. Change the string set(assemble_tgz OFF) to set(assemble_tgz ON) in CMakeLists.txt

nano CMakeLists.txt

3. Build the Project

./build.sh

4. Move .tar.gz file from build folder to any folder and unpack it

5. Run the program to check it from unpacked folder

./chloro -h

For more convenience add the application path into .bashrc file

export PATH="$PATH:/path/to/application/folder"

This will allow you to run the application in terminal directly

chloro -h
