Print

Log a message by wrapping the CMake message() command to extend its functionalities .It requires CMake 3.20 or newer.

Synopsis

Print Formated Message
  print([<mode>] "message with format text" <argument>...)

Print Path List
  print([<mode>] PATHS <file-path>... [INDENT])

Print String List
  print([<mode>] STRINGS <string>... [INDENT])

Module Variables

PRINT_BASE_DIR

Specifies the base directory used to compute relative paths in the print(normal) commands. Its default value is CMAKE_SOURCE_DIR.

Usage

print([<mode>] "message with format text" <argument>...)

Record the specified message text in the log, optionally specifying a message mode. This command is inspired by the message() command from CMake and the C printf() function.

If specified, the optional <mode> keyword must be one of the standard message modes accepted by the message() command, such as STATUS, WARNING, ERROR, etc.

The "text to print" may contain one or more custom conversion directives enclosed in @ characters. These directives will be replaced using the provided arguments, in the order they are given. Text without directives is equivalent to a call to message() command.

Each directive takes the form @specifier@, where specifier is one of the following:

@ap@

Converts the corresponding argument into an absolute path to an existing file or directory.

@rp@

Converts the corresponding argument into a path relative to the value of the PRINT_BASE_DIR variable. The file or the directory must exist on the disk.

Example usage:

# Case 1: Without mode
set(PRINT_BASE_DIR "${CMAKE_SOURCE_DIR}")
set(my_path "src/main.cpp")
print("Absolute: @ap@, Relative: @rp@" "${my_path}" "${my_path}")
# output is:
#   Absolute: /full/path/to/src/main.cpp, Relative: src/main.cpp

# Case 2: With status mode
set(PRINT_BASE_DIR "${CMAKE_SOURCE_DIR}")
set(my_path "src/main.cpp")
print(STATUS "Absolute: @ap@, Relative: @rp@" "${my_path}" "${my_path}")
# output is:
#   -- Absolute: /full/path/to/src/main.cpp, Relative: src/main.cpp

print([<mode>] PATHS <file-path>... [INDENT])

Record in the log each file from the specified <file-path> list after converting them to paths relative to the value of the PRINT_BASE_DIR variable. This command is inspired by the message() command from CMake.

The optional <mode> argument determines the message type and may be any of the standard message modes supported by the message() command, such as STATUS, WARNING, ERROR, etc.

If the INDENT option is specified, the output message is indented by two spaces. This affects the indentation level of the printed message using the internal CMAKE_MESSAGE_INDENT stack.

Example usage:

set(PRINT_BASE_DIR "${CMAKE_SOURCE_DIR}")
set(my_files "${CMAKE_SOURCE_DIR}/src/main.cpp" "${CMAKE_SOURCE_DIR}/include/lib.hpp")
print(STATUS PATHS ${my_files} INDENT)
# output is:
#   src/main.cpp ; include/lib.hpp

print([<mode>] STRINGS <string>... [INDENT])

Record in the log each string from the given <string> list. This command is inspired by the message() command from CMake.

If specified, the optional <mode> keyword must be one of the standard message modes accepted by the message() command, such as STATUS, WARNING, ERROR, etc.

If the INDENT option is specified, the output message is indented by two spaces. This affects the indentation level of the printed message using the internal CMAKE_MESSAGE_INDENT stack.

Example usage:

set(my_list "one" "two" "three")
print(STATUS STRINGS ${my_list} INDENT)
# output is:
#   one ; two ; three
