The short Command



The short command is the SmartEiffel interface generator. Using a plain Eiffel source file, the short command prints on the standard output the interface of this class. The short command is also a good tool to performs many validity checks of a given class (syntax, exportation rules, inheritance, etc.). There are two invocation modes: traditional and ACE.

Note that features from ANY are not printed unless the class you are shorting is ANY or feature from ANY is redefined.

Usage

Traditional mode
se short [format] [options] <Class>

ACE mode
se short [format] [options] <ACEfile.ace> <Class>

The short command prints on the standard output the interface of the given <Class>.
The default format is -plain: no special characters are added.
The short command is customisable and some predefined formats are already available (see below for predefined formats and how to add a new output format). When ACE mode is used, as usual, the "loadpath.se" is ignored and only the content of the ACE file is used to look for the Eiffel source code.

Options

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

-verbose:
Print system information during the compilation (full path of files loaded, type inference score, removed files, etc.).

-version:
Display the version number of the SmartEiffel release you're using.

-loadpath <loadpath_file>:
Adds a loadpath file for class lookup. See details in the finder man page.
-sort:
Features are sorted alphabetically.

-short:
Does not consider inherited features.

-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:
Suppresses output for all warning messages (error messages are still printed). Implies -no_style_warning.

-client <client_class>:
Specify the class whom the point of view is taken of. This command allow to know all features visible to client_class from the class you short.
Note1: default is equivalent to -client ANY.
Note2: se short -client class class does not show all features from class, only features exported to itself are printed (callable via qualified calls).
-all_clients:
To display all features even those which are not exported.
Predefined Output Formats
-plain:
The default compact output format. No special character added.

-pretty:
Basically, it is similar to -plain except that there are a couple of additional line-feeds (e.g. between features) that make the structure of the output easier to read. (It sort of appears like the "pretty" printer would have done it, that's why "-pretty").

-tex1:
Simple output mode for TeX. Encloses the interface in a simple verbatim TeX environment.

-tex2:
Output mode for TeX. Uses a TeX alltt environment with a \bf font for keywords, \it font for comments and \tt font for identifiers.

-tex3:
Output mode for TeX. Follows style guidelines given in ETL appendix A. As the previous mode, this mode also uses a TeX alltt environment.

-html1:
A nice HTML output (provided by Matthias Klose).

-html2:
Another nice HTML output too. This one is the one used to generate the library interface of the SmartEiffel WEB site.

-html_css:
A nice HTML+CSS output (provided by John E. Perry). The CSS file is seshort.css.


Adding a New Output Format

To define a new output format, you have to add a new sub-directory in the SmartEiffel "short" directory. In order to change the output, this new directory must contains various hook files, which contain text used to replace the default output.
Here is the current list of hook files.

    1. Changing the output for the class interface header

"hook000" - If this hook file exists, the contents of this file is printed very first.

"hook010" - If this hook file exists, and if the processed class is an expanded one, the contents of this file is printed before the class name to replace the default string "expanded class interface ".

"hook011" - If this hook file exists, and if the processed class is an deferred one, the contents of this file is printed before the class name to replace the default string "deferred class interface ".

"hook012" - If this hook file exists, and if the processed class is an ordinary one (not deferred nor expanded) the contents of this file is printed before the class name to replace the default string "class interface ".

"hook013" _ If this hook file exists, the contents of this file is printed before the class name whatever the kind of class (expanded, deferred or ordinary) to replace the default empty string "".

"hook014" - If this hook exists, the contents of the file is printed after the class name to replace the default string "%N".

"hook015" - If this hook file exists, and if a class header comment is present, this file is printed once before the heading class comment.
