Crystal lang : How to indicate require path for crystal compiler

Question

If some of my libraries locate out of default directory lib, could I indicate the require path to compile successfully without lib directory nor shards.yml.

Answer 1

Yes, change the CRYSTAL_PATH environment variable. By default it's $CRYSTAL_ROOT/src:lib (the src directory of the installation, and then the relative lib directory). Just add :some_other_dir at the end of that.

Example: CRYSTAL_PATH=$CRYSTAL_ROOT/src:lib:~/my_lib_dir
