Configuration

If configuration values are not provided as CLI arguments the program will first attempt to load them from the --config option and, after that, look for the environment variables and overwrite any options set by the configuration file. This way the order of preference is CLI args > environment > configuration file.

Example config.yaml file:

root: https://api.hackerschool.dev
user: username 
password: password
cookiejar: ./cookiejar.json

Example .env file:

export HS_ROOT="https://api.hackerschool.dev"
export HS_USER="username"
export HS_PASSWORD="password"
export HS_HS_COOKIERJAR="/home/my/cookiejar.json"

Examples

Configuration

Example using CLI options:

hscli -r https://api.hackerschool.dev -u username -p password -c cookiejar.json -d login 

Example using config.yaml file:

hscli --config config.yaml -d login

Example using .env file:

source .env; hscli -d login

The source command only needs to be ran once per shell session.

Command Arguments

For commands that expect a payload, such as mcreate, the [<file>] argument is optional, if ommited, the program will attempt to read the payload from standard input. This allows for some flexibility, e.g, the two following examples accomplish the same:

hscli mcreate member.json 

cat member.json | hscli mcreate

Exit Codes

The program returns 1 for API errors and 2 for other errors, e.g, "no connection to host", etc. This can be leveraged for scripting.

hscli -d mget username > /dev/null
if [ $? -eq 0 ]; then
    hscli -d mgetlogo username > logos/username.png
    echo "Logo saved sufessfully!"
elif [ $? -eq 1 ]; then
    echo "API Error!"
else
    echo "Error!"
fi

This sript will save the logo of a user if it exists.

Output

The program writes raw JSON to stdout and error and log messages to stderr. Because of this it's recommended to make use of other programs such as jq.

hscli mgetall | jq

hscli maddtag dev_tag.json | jq

hscli pmembers proj_name | jq

cat updated_project.json | hscli update proj_name | jq
