The short command is the SmartEiffel interface generator. Using a plain Eiffel source file, the command prints on the standard output the interface of this class. It is also a good tool to perform many validity checks of a given class (syntax, exportation rules, inheritance, etc.).
In a normal installation, it is invoked by the command se short.
There are two ways of invoking it: the traditional mode and the ACE mode.
- In the traditional mode, many options can be specified on the command line.
- In the ACE mode (Assembly of Classes in Eiffel), most of its options are not allowed on the
command line; they have their equivalents in the ACE file.
Synopsis
se short [options] <class>se short [options] <ace_file.ace> <class>
The first syntax is the traditional mode, the second is the ACE mode.
In the ACE mode, the name of the ACE file provided must end with the suffix .ace.
Options
-help
|
Display a short summary of the command line syntax, as well as a complete list of the compiler's options.
|
-verbose
|
Display (an enormous amount of) information during the compilation: a complete list of files loaded, the type inference scores, the generated files, and so on.
|
-version
|
Display the SmartEiffel version number.
|
-loadpath <loadpath-file>
|
Adds a loadpath file for class lookup. See details in the finder page.
|
-sort
|
Sort features alphabetically.
|
-short
|
Show only locally defined features (do not consider purely inherited features).
|
-no_style_warning
|
Suppress the display of warning messages about non-compliance with Eiffel style rules (this flag does not have any effect any more in 2.3).
|
-no_warning
|
Suppress all warning messages. This implies -no_style_warning.
|
-client <client_class>
|
Specify the class whom the point of view is taken of. This command allows to know all the features visible to client_class from the class you short.
Note1: the default is equivalent to -client ANY.
Note2: se short -client STRING STRING does not show all features from STRING, but only those that are exported to STRING itself (callable via qualified calls).
|
-all_clients
|
Display all the features, aven those not exported at all (marked feature {})
|
Predefined Output Formats
You can specify an output format, which will change some typographic details but not the contents itself (see [#Options the options above] to change the contents.
See also [#Adding_a_new_output_format below] to know how to add a new output format.
-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).
|
-tex1
|
Simple output mode for TeX.
|
-tex2
|
Output mode for TeX. Uses a bold font for keywords, an italic font for comments and a fixed font for identifiers.
|
-tex3
|
Output mode for TeX. Follows style guidelines given in ETL2 appendix A.
|
-html1
|
A nice HTML output (provided by Matthias Klose).
|
-html2
|
Another nice HTML output.
|
-html_css
|
A nice HTML+CSS output (provided by John E. Perry). The CSS file must be called seshort.css.
|
Adding a new 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 contain hook files, which contain the text used to replace the default output.
Here is the current list of hook files.
| hook000
|
If this hook file exists, the contents of this file is printed very first.

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 ".
