gnatprep:tldr:88033
The command gnatprep
is a command line tool used in Ada programming language development. This command is typically used as part of the build process to preprocess Ada source files.
The specific command you mentioned gnatprep ${source_file} ${target_file} ${definitions_file}
is used to invoke gnatprep
with three parameters:
-
${source_file}
: This is a placeholder representing the source file that needs to be preprocessed. You need to replace${source_file}
with the actual file name (including the path if necessary) of the Ada source file you want to preprocess. -
${target_file}
: This is a placeholder representing the target file where the preprocessed output will be written. You need to replace${target_file}
with the desired file name (including the path if necessary) for the resulting preprocessed file. -
${definitions_file}
: This is a placeholder representing a file containing definitions used during preprocessing. It provides values for placeholders (also known as macros) used in the Ada source file. You need to replace${definitions_file}
with the actual file name (including the path if necessary) of the definitions file you want to use.
When you execute this command, gnatprep
will read the source file, replace any placeholders in the file with the corresponding values specified in the definitions file, and then write the preprocessed output to the target file.
Overall, this command is useful for performing preprocessor operations on Ada source files, which can help in generating different versions of the code, altering behavior, or implementing conditional compilation based on configuration options.
