Synopsis

Are you getting sick of always writing the same piece of code to get various command line arguments? Well, search no more since Simple C++ CmdLineParser does this job for you! Indeed, as a header-only library you just have to #include "CmdLineParser.h" at the beginning of you code, and that's all: no extra library to include, you're in! :D

Example

As an example is always better to show a summary of what it does, take a look at the example/main.cpp file:

Running the example

You want to run the example? There you go!

mkdir build
cd build
cmake ..
make

# Command example
./OptionParserExample -o "test lol" -i 15 -d 1549846.654654355 -iii 13 15 16 -ss test.txt foo.bar

# With Yaml example:
./OptionParserExample -y ../resources/configExample.yaml --trigger

# Also works with a JSON file!
./OptionParserExample -y ../resources/configExample.json

GNU-like parsing

GNU libraries standardised the CLI format. If you like the way how it was done, you can process the arguments in the same way after enabling "GNU mode" with clParser.setIsUnixGNU(true);. With this mode short arguments could be merged together and long arguments can be separated with =. See examples below.

# if 'a', 'b', 'c' are trigger options
./app.exe -abc == ./app.exe -a -b -c
# if '-i' expects parameter
./app.exe -iblabla == ./app.exe -i blabla
# separation with '=' sign
./app.exe --input=../test.dat == ./app.exe --input ../test.dat
