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.
