wrapper script for cd (change directory) to simplify the cd ../../../.. statement
#!/bin/bash
# wrapper for the cd command
# it expands sequence .... to ../../../../ (each dot becomes a ../ )
# example: ' cd .... ' -> ' cd ../../../../ '
# if the command does not match ' cd ..[.]+ ' , it is passed directly to the cd command
# alias cd=". /path/to/mycd.sh"

Get arguments of a cling interpreter instance with reflection

To get the arguments of cling, which are passed on start, you can use the reflection feature of cling.

#include "cling/Interpreter/Interpreter.h"
#include "cling/Interpreter/InvocationOptions.h"

// gCling is an object of type cling::Interpreter
std::vector<const char*> remaining = gCling->getOptions().CompilerOpts.Remaining;

Integrate Spack modules in conda environment.

About

Automatic loading of Spack modules when the Conda environment is loaded.

Helper function

Spack and Conda can influence each other with side effects. Therefore I do not activate them by default. The following functions allow you to activate Conda and Spack by bash command.

# for example, add to .bashrc
