The pretty Command

Usage

pretty [options] <class_name> ...

Command pretty is the SmartEiffel pretty printer for Eiffel source files. The class_name argument can be a classic Eiffel class name as for example "INTEGER" or the name of some file as for example "integer.e". The class file to be treated by pretty is always searched in the current working directory.
One can specify more than one class name (or 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. Pseudo variable Current is never printed (unless it is necessary). No end mark comment for routines. No end comments for constructs (if, inspect, debug, ...). Very compact printing.
-default:: the default mode. Don't change printing of pseudo variable Current (if Current is in the input, Current is in the output). Print end comment of routines. Don't print end comments for constructs (if, inspect, debug, ...).
-end:: Same printing as previous mode but print ends of all constructs (if, inspect, debug, ...).
-parano:: Same printing as previous mode but prints Current everywhere you can.
-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 writting 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.
