Commandbox Usage

Parameters

# Named parameters
server start port=8080 host=localhost

# Positional parameters
install coldbox

# Boolean flags
install coldbox --verbose
install coldbox --noSave
server start --noSaveSettings --noOpenBrowser

# Quoted values with spaces
package set description="My great app"

# JSON values
config set myArray="['a','b','c']"

Default Command Parameters

# Store defaults so you don't have to type them every time
command params set "server start" openBrowser=false
command params set "install" --verbose

# See current defaults
command params show "server start"

# Clear defaults
command params clear "server start"

Escaping Special Characters

# Escape equals sign
echo foo\=bar

# Escape backtick (used for expressions)
echo \`notAnExpression\`

System Settings (Dynamic Placeholders)

System settings allow dynamic values from JVM properties and OS environment variables:

# Use an env var
echo ${PATH}
echo ${HOME}

# With default value if not found
server start port=${SERVER_PORT:8080}
server set web.host=${SERVER_HOST:localhost}

Lookup order (first match wins):

1. Per-command env vars
2. Parent command env vars
3. Global shell env vars
4. JVM System Properties
5. OS Environment Variables

In server.json and box.json:

{
    "web": {
        "http": {
            "port": "${WEB_PORT:8080}"
        }
    }
}

# System setting expansion namespaces
echo ${server::web.http.port}        # from server.json
echo ${box::version}                 # from box.json
echo ${config::name}                 # from CommandBox config
echo ${env::MY_VAR}                  # force OS env var lookup
echo ${java::user.home}              # JVM system property

Environment Variables (Shell)

# Set global shell variable
set foo=bar
env set foo=bar

# Read variable
env show foo
echo ${foo}
echo ${foo:default}

# Clear variable
env clear foo

# Show all shell variables
env show

# Debug variable hierarchy
env debug

Per-command variables (scoped to that command only):

# Variable set in expression only exists there
echo `set myVar=cheese && echo ${myVar}`
env show myVar myDefault   # outputs "myDefault"

Expressions & Piping

# Backtick expressions — command result is substituted
echo `package show version`
package set version=`package show version`

# Pipe output to another command
package show dependencies | foreach "echo 'Package: ${item}'"

# Pipe into commands
echo "coldbox" | install

# Chain commands with &&
install coldbox && server start

Recipes

Recipes are scripts of CommandBox commands run in a subshell:

# Create a recipe file: myRecipe.boxr
echo "install coldbox"
echo "server start"

# Run it
recipe myRecipe.boxr

# Pipe commands as a recipe
echo "upgrade; version" | recipe

# Inline recipe with semicolons
recipe "install coldbox; server start; testbox run"

Foreach (Looping)

# Loop over comma-separated list
foreach "foo,bar,baz" "echo 'Item: ${item}'"

# Loop over command output
package show dependencies | foreach "echo 'Dep: ${item}'"

# Loop with custom delimiter
foreach delimiter="|" "a|b|c" "echo ${item}"

# Loop with index
foreach "a,b,c" "echo '${index}: ${item}'"

REPL (Interactive Evaluation)

# Start the REPL
repl

# In the REPL — evaluate CFML/BoxLang
now()
createUUID()
x = 5; y = 10; x + y

# Exit REPL
exit
