Look up project directory based on a locator file.
Never write ../../ relative path format.
For example, suppose that there are below files structure:
/example
│
├── .project_locator
├── A
│ ├── file-1
│ ├── file-2
│ ├── file-3
│ └── C
│ └── script-c.sh
└── B
└── script-b.sh
You created a empty file named .project_locator in project root directory.
And then you could get the ROOT_DIR path via lookup_dir.
# in /example/B/script-b.sh
source lookup.sh
ROOT_DIR=$(lookup_dir)
echo $ROOT_DIR # => /example
# in /example/C/script-c.sh
source lookup.sh
ROOT_DIR=$(lookup_dir)
echo $ROOT_DIR # => /example
If you put another .project_locator in /example/A/.project_locator
/example
│
├── .project_locator
├── A
│ ├── .project_locator
│ ├── file-1
│ ├── file-2
│ ├── file-3
│ └── C
│ └── script-c.sh
└── B
└── script-b.sh
# in /example/C/script-c.sh
source lookup.sh
ROOT_DIR=$(lookup_dir)
echo $ROOT_DIR # => /example/A
