print

Print values to script output (stdout in the CLI). Arrays render as headerless tables: a flat array as one row, an array of arrays as one row per inner array.

Smart blocks: build-time inputs only. Logging consumes build-time values and cannot preview a guaranteed on-chain result.

Syntax

print [...values]

Arguments

Name	Type	Evaluation	Description
[...values]	any	Build time	Values to output, space-separated

Options

Name	Type	Evaluation	Description
--headers	array	Build time	Column headers; renders the printed arrays as a table, one array per column

Examples

# Print a string
print "hello"

# Print multiple values
print "count:" 42

# Print variables
set $name "world"
print "hello" $name

# Print an array as a one-row table
print [1 2 3]

# Print an array of arrays as table rows
print [[alice 10] [bob 20]]

# Print column arrays as a table
print [[alice bob] [10 20]] --headers [Name Score]

Export output

The CLI sends printed text to stdout and status messages to stderr. Each print adds a newline, preserving existing text and table formatting.

evmcrispr run export.evml > output.txt

Redirection is shell syntax, not EVML syntax. The terminal's Download output exports the same printed text as output.txt. Print only a JSON package when exporting a JSON file; additional prints would also be included.

Programmatic hosts can capture printed messages with onOutput. Messages do not include the terminating newline; hosts append it when exporting. Without onOutput, printed messages continue to use onLog.
