NAME

       unitdiff - Describe differences in the interface of a FPC unit.

SYNOPSIS

       unitdiff  [  --disable-arguments]  [ --disable-private] [ --disable-protected] [ --help] [
       --lang=language] [ --list] [ --output=filename] [ --sparse] file1 file2

Description

       unitdiff scans one or two Free Pascal unit source files and  either  lists  all  available
       identifiers, or describes the differences in identifiers between the two units.

Usage

       You  can invoke unitdiff with as the only required argument a input filename. It will then
       simply list all available identifiers.

       The regular use is to invoke unitdiff with input1 input2 arguments. It will then show  the
       difference  in  interface between the two units, or list the available identifiers in both
       units. The output of unitdiff will go to standard output by default.

Options

       unitdiff has some options, most of them optional, defaults will be used in most cases.

       --disable-arguments
              If this option is specified, unitdiff will not check the arguments of functions and
              procedures. By default, these are checked as well.

       --disable-private
              By  default,  private  methods of classes are checked. if this option is specified,
              private fields or methods are not checked.

       --disable-protected
              By default, protected  methods of classes are checked. if this option is specified,
              protected and private fields or methods are not checked.

       --help Emit a short help text and exit.

       --lang=language
              Sets  the  language  for the output file. This will mainly set the strings used for
              the headers in various parts of the documentation  files  (by  default  they're  in
              english). Currently, valid options are

              de     German.

              fr     French.

              nl     Dutch.

       --list If  this  option  is  specified,  only  the  list  of available identifiers will be
              specified for the unit or units. If only  1  unit  is  specified,  this  option  is
              automatically assumed.

       --output=filename
              This  option  tells  unitdiff  where  the  output  should go. If this option is not
              specified, the output is sent to standard output (the screen).

       --sparse
              Turns on sparse mode. In this mode, the output will not contain the  types  of  the
              identifiers.  Only  the  names  of  the  identifiers  are written to the output. By
              default, also type descriptions are written.
