Using gedoc |

## Command-line options

The usual way to invoke gedoc is as follows:

> `gedoc --format=<output_format> --output=<output_directory> <input_filename>`

This will read the description of your Eiffel project from the Xace or ECF file `input_filename`, analyze it, and generate the documentation files in directory `output_directory` using the format `output_format`. Note that in addition to Xace and ECF, the file `input_filename` can also be an Eiffel class file. In that case, your Eiffel project will be considered to be made up of only one Eiffel class. This is useful when we just want to pretty-print one Eiffel file.

Here is the list of options that can be used with gedoc:

`-h`
`--help`
  Print a summary of the command-line options of gedoc and exit.
`--format=<pretty_print|html_ise_stylesheet>`
  Format for the output. (default: `pretty_print`) The formats currently supported are `pretty_print` to use gedoc as an Eiffel pretty-printer, and `html_ise_stylesheet` to generate HTML documentation using ISE's stylesheet.
`-c <class_name>`
`--class=<class_name>`
  Name of classes to be processed. (default: process all classes in the Eiffel project) The name can contain wildcards such as `FOO*` or `@(FOO|BAR)`. This option can be used several times to specify several class names.
`-o <directory_name>`
`--output=<directory_name>`
  Directory for generated files. (default: next to each class file)
`--library-prefix`
  Add subfolders with library names in the output directory.
`-f`
`--force`
  Overwrite existing files without asking.
`-i`
`--interactive`
  Ask before overwriting a file, unless `--force` is specified.
`--ise[=major[.minor[.revision[.build]]]]`
  Version of Eiffel whose semantics should be used during code analysis. (default: latest version)
`--define=NAME=VALUE`
  Define variables to be used when reading Xace files. This option can be used several times to define several variables.
`--silent`
  Run gedoc in silent mode.
`--verbose`
  Run gedoc in verbose mode.
`-V`
`--version`
  Print the version number of gedoc and exit.
