The pretty Command

Usage

pretty [options] <source_file> ...

Command pretty is the SmartEiffel pretty printer for Eiffel source files. The source_file argument must be some existing Eiffel source file path as for example "integer.e" or "lib/kernel/integer.e".
One can specify more than one file name at a time in order to apply pretty on many files. All the corresponding files are reprinted in a pretty way.

There are four modes of pretty printing -zen, -default, -end and -parano mode. Only one mode can be selected and mode -default is the default mode.

Options for Pretty Printing

-help:: Display a brief summary of the command-line syntax and a complete list of pretty options.

-version:: Show the number of the version of SmartEiffel you're using.
-zen:: The less you can print (i.e. very compact output). No end mark comment for routines. No end comments for statements (if, inspect, debug, ...).
-default:: The default mode. This is close to what we are using for our library.
-end:: Same printing as for previous mode but also print end mark comments for all routines.
-parano:: Same printing as for previous mode but also print end mark comments for all statements (if, inspect, debug, ...).
-no_style_warning:: Suppress output for warning messages related to non respect of standard Eiffel style guidelines (for example ItEm will not trigger a warning).
-no_warning:: Suppress output for all warning messages (error messages are still printed).

Security and BackUp File

For the security of sources files, a backup file is created before writing the new file (system or command pretty may crash during printing of the new file). The backup file name is "foo.bak" when source file name is "foo.e". Backup file is written in the same directory as source file.

If an old backup file already exists before pretty printing, command pretty exit with an error message. To be sure that the pretty printing is well done, the output file is parsed again.

Even if second parsing gives no errors, backup file is NOT removed. Thus you can recompile your Eiffel code to check new file before removing backup file by yourself.
