Using gelint |

## Command-line options

The usual way to invoke gelint is as follows:

> `gelint ecf_filename`

This will read the description of your Eiffel system in the ECF file `ecf_filename`, perform code analysis on the corresponding Eiffel classes and report any syntax or validity errors. Your Eiffel system can be an Eiffel project or an Eiffel library.

For simple programs, one can just provide the Eiffel file containing the root class:

> `gec eiffel_filename`

This will perform the code analysis on all classes reachable from that class, starting from its first creation procedure as root creation procedure.

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

`-h`
`--help`
  Print a summary of the command-line options of gelint and exit.
`--target=<target_name>`
  Name of target to be used in ECF file. (default: last target in ECF file)
`--flat`
  For each class, not only check the validity of the features declared in this class, but also of those inherited from its parent classes.
`--noflatdbc`
  Do not check the validity of inherited pre- and postconditions when a feature is redeclared.
`--catcall`
  Report possible CAT-call errors, based on the statically computed dynamic type sets of each variables in the Eiffel code.
`--ecma`
  Strictly follow the ECMA Eiffel standard during code analysis.
`--ise[=major[.minor[.revision[.build]]]]`
  Version of ISE Eiffel whose semantics should be used during code analysis.
`--setting=name=value`
  Override settings defined in ECF file. This option can be used several times to override several settings.
`--capability=name=value`
  Override capability usage defined in ECF file. This option can be used several times to override several capabilities.
`--variable=NAME=VALUE`
  Override variables defined in ECF file. This option can be used several times to override several variables.
`--thread=<thread_count>`
  Number of threads to be used to run gelint. Negative numbers -N mean "number of CPUs - N". (default: -3, aka "max (number of CPUs -3, 1)")
`--silent`
  Run gelint in silent mode.
`--verbose`
  Run gelint in verbose mode.
`--no-benchmark`
  Should no benchmark information be displayed? (default: display non-nested benchmark information)
`--nested-benchmark`
  Should nested benchmark information be displayed?
`--metrics`
  Should metrics information be displayed?
`-V`
`--version`
  Print the version number of gelint and exit.
