.Os Darwin
.Sh NAME
.Nm Portfile
.Nd MacPorts description file reference
.Sh DESCRIPTION
A complete reference of all available
.Nm
variables and example syntax.
.Nm Portfiles
consist of valid TCL, allowing for simple key/value pair syntax as well
as utilization of TCL's extensive functionality.
.Nm Portfiles
are encoded in UTF-8.
.Pp
The
.Nm MacPorts System
uses a target dependency system based on a depends/provides model, allowing
for targets to be registered and executed in the correct order based on their
individual requirements.
.Pp
A
.Nm
author needs to be aware of the various standard targets, the options
that they require and the variables that both the targets and the port
system provide.
.Sh PORTSYSTEM
Portfiles must begin with a PortSystem line that defines which version of the
Portfile interpreter should be used.
.br
.Sy Synopsis:
.Dl PortSystem 1.0
.Sh MAIN VARIABLES
All ports are required to set certain variables.
.Bl -tag -width lc
.It Ic name
Full name of port.
.br
.Sy Type:
.Em required
.br
.Sy Example:
.Dl name XFree86
.It Ic version
Upstream version of software.
.br
.Sy Type:
.Em required
.br
.Sy Example:
.Dl version 4.2.1
.It Ic epoch
If a port's version numbering changes such that a newer version looks
older than the previous version, the
.Ic epoch
should be increased.
Some
.Nm Portfile
authors have used large
.Ic epoch
values that look like a date, but there is no reason to do so.
The
.Ic epoch
is simply an unsigned integer, and the only requirement is that it never be
decreased.
.br
.Sy Type:
.Em optional
.br
.Sy Default:
.Em 0
.br
.Sy Example:
.Dl epoch 1
.It Ic description
One-line description of the software and what it does.
To appear in the description, brackets and semi-colons need to be escaped with
a backslash (i.e., they must be written as
.Ql \e[ ,
.Ql \e]
and
.Ql \e; ) .
The escape sequences listed in
.Xr re_syntax n
may also be used, with the exception of
.Ql \en ,
.Ql \er
and
.Ql \ef .
.br
.Sy Type:
.Em required
.br
.Sy Example:
.Dl description IMAP email checker
.It Ic long_description
A verbose description of the software and what it does.
To appear in the description, brackets and semi-colons need to be escaped with
a backslash (i.e., they must be written as
.Ql \e[ ,
.Ql \e]
and
.Ql \e; ) .
The escape sequences listed in
.Xr re_syntax n
may also be used, with the exception of
.Ql \en ,
.Ql \er
and
.Ql \ef .
.br
.Sy Type:
.Em required
.br
.Sy Example:
.Bd -literal -offset indent -compact
long_description The GNU Image Manipulation \e
    Program (GIMP) is a powerful tool for the \e
    preparation and manipulation of digital \e
    images. The GIMP provides the user with a \e
    wide variety of image manipulation, painting, \e
    processing, and rendering tools.
.Ed
.It Ic notes
Notes for setup and use of the port.
This is shown after the port is activated and anytime the
.Ic notes
command is used; for example:
.Pp
.Dl "port notes python26"
.Pp
The advantage to using
.Ic notes
instead of
.Ic ui_msg
is that it can be queried after a port is installed but
.Ic ui_msg
is only printed during an install.
Therefore
.Ic notes
is good for any information which may be needed anytime after an install.
.br
.Sy Type:
.Em optional
.br
.Sy Example:
.Bd -literal -offset indent -compact
notes "
To fully complete your installation and make\e
python ${branch} the default, please run:

  sudo port install python_select
  sudo python_select ${name}

.It Ic supported_archs
The CPU architectures for which this port can be built.
Archs currently supported by macOS are:
.Em i386 ,
.Em ppc ,

.Em ppc7400 ,
and
.Em x86_64 .
If this option is not set, it is assumed that the port can build for all
archs.
If a port does not install any architecture-specific files, use the special
value noarch.
.br
If the building architecture isn't among
.Ic supported_archs ,
port fails with an error message except when building on
.Em x86_64
(or
.Em ppc64 )
and
.Ic supported_archs
contains
.Em i386
(or
.Em ppc ) .
In this case, the port will be built in 32-bit mode.

.Ed
.It Ic installs_libs
By default, it is assumed that ports may install libraries or headers that can
be incorporated into their dependents.
If this is not the case, set
.Cm installs_libs
to
.Em no .
This means that this port's dependents need not check that it is installed
for the same architectures as them; that it is permissible to distribute
binaries of the dependents even if their licenses conflict with the license
of this port; and that updates to this port can never result in broken dynamic
linking in its dependents.
.br
.Sy Type:
.Em optional
.br
.Sy Default:
.Em none
.br
.Sy Example:
.Dl installs_libs no
.It Ic license_noconflict
By default, it is assumed that ports may use libraries or headers from their
dependencies and thus form a derivative work.
A dependency with an incompatible license thus prevents the port from being
distributed in binary form.
If a dependency with an incompatible license is not used in such a way that a
derivative work is formed, or should not prevent binary distribution for any
other reason, add its name to this list.
.br
.Sy Type:
.Em optional
.br
.Sy Default:
.Em none
.br
.Sy Example:
.Dl license_noconflict openssl
.Dl license_noconflict readline gdbm

.Sh DEPENDENCY OPTIONS
Port dependencies should refer to other MacPorts ports
whenever possible, therefore each dependency should be
expressed in the format:
.Bl -tag -width ls -offset indent
.It Li port: Ns Aq port
.El
.Pp
Where
.Aq port
represents the name of an existing MacPorts
.Nm port .
If satisfying a dependency with a MacPorts port is not
practical and it is likely that a dependency must be met
by an Apple optional install, then the alternative dependency
format:
.Bl -tag -width lc -offset indent
.It Ar type Ns Li \&: Ns Ao filename Ac Ns Li \&: Ns Aq port
.El
.Pp
may be used.
Where
.Ar type
is
.Dq bin
if
.Aq filename
is a program,
.Dq lib
if it is a library, or
.Dq path
if it is a path to an installed file.

.Sh VARIANT OPTIONS
MacPorts allows for conditional modification to be specified in a
.Nm ,
allowing for user-customization of a software's build-time settings.
.Bl -tag -width lc
.It Xo
.Ic variant
.Op Cm requires Ar variant
.Op Cm conflicts Ar variant
.Op Cm description Ar "description"
.Xc
The value is usually a TCL script which modifies one or more
.Nm
variables.
Dependencies and conflicts with other variants in the same port can be
expressed with
.Cm requires
and
.Cm conflicts .
.Cm description
provides a means to supply a description of the variant for the user.
.br
.Sy Type:
.Em optional
.br
.Sy Example:
Add a
.Dq gnome
variant to a port.
.Bd -literal -offset indent -compact
variant gnome requires glib \e
    { configure.args-append --with-gnome \e
      depends_lib-append port:gnome-session }
.Ed
.It Ic default_variants
If variants are defined, then the
.Ic default_variants
value lists which variants are enabled by default.
.br
.Sy Type:
.Em optional
.br
.Sy Example:
.Dl default_variants +ssl +tcpd
.It Ic universal_variant
When using MacPorts on macOS, a universal variant is defined and
the default behavior is to configure ports with universal flags
(see the
.Ic UNIVERSAL TARGET HOOKS
section above).
The variant can be overridden if the default code does not work.
It can also be suppressed if having a universal variant for the port does not
make sense.
To suppress it, use the
.Ic universal_variant
option.
.br
.Sy Type:
.Em optional
.br
.Sy Default:
.Em yes
.br
.Sy Example:
.Dl universal_variant no
.El
.Sh PLATFORM OPTIONS
MacPorts allows for platform-specific conditional code to be
specified in a
.Nm ,
for handling differences between platforms and
versions of the same platform.
.Bl -tag -width lc
.It Xo
.Ic platform
.Ar platform
.Op Ar version
.Op Ar arch
.Ar body
.Xc
The body is executed if the given platform/version/arch combination matches
.Ic os.platform
or
.Ic os.subplatform
and/or
.Ic os.major
and/or
.Ic os.arch .
The following examples are from the
.Pa lang/php5 ,
.Pa audio/flac
and
.Pa sysutils/getopt
.Nm Portfiles ,
respectively.
.br
.Sy Type:
.Em optional
.br
.Sy Examples:
.Bd -literal -offset indent -compact
platform darwin 10 \e
    { configure.env-append LIBS=-lresolv }
platform darwin i386 \e
    { configure.args-append --disable-asm-optimizations }
platform darwin 8 powerpc \e
    { configure.universal_ldflags-append -liconv }
.Ed
.El
.Sh PORTGROUP
To factorize the work with similar ports, MacPorts provides the notion of
.Nm PortGroup
that can be used to load definitions for a given class or group of ports.
See
.Xr portgroup 7
for more details on the various
.Nm PortGroup
classes.
.Sh TCL EXTENSIONS
A number of TCL extensions are available for use in
.Nm Portfiles .

Install file(s) to a target file or directory.
The options are intended to be compatible with
.Xr install 1 :
.Bl -tag -width indent
.It Fl b
Backup any existing files with an
.Pa .old
extension.
.It Fl B
Specify a different backup suffix for the
.Fl b
flag.
.It Fl c
Install files (this is the default).
.It Fl C
Only copy a file if it is different.
.It Fl d
Create directories, including (if necessary) parent directories.
.It Fl f
Specify target flags, see
.Xr chflags 1
for details.
.It Fl g
Specify the group.
.It Fl M
Disable use of
.Xr mmap 2 .
.It Fl m
Specify an alternate mode.
The default is 0755.
See
.Xr chmod 1
for details.
.It Fl p
Preserve the modification time.
.It Fl S
Copy safely, using a temporary file.
.It Fl s
Strip binaries using
.Xr strip 1 .
.It Fl W
Change to

before working.
.El
.El
.It Xo
.Ic fs-traverse
.Op Fl depth
.Op Fl ignoreErrors
.Op Fl tails
.Op Fl -
.Ar varname
.Ar target-list
.Ar body
.Xc
Traverse the filesystem hierarchy rooted in each element of
.Ar target-list
and execute
.Ar body
for each found file/directory.
.Va target-list
should always be specified as a list even if contains only one item.
.Va varname
is set to the path of the file/directory.
If
.Ic break
is called during execution, the filesystem traversal is stopped.
If
.Ic continue
is called during execution, the current file and any children are skipped
and traversal continues with the next file/directory.
.Bl -tag -width indent
.It Fl depth
Equivalent to the
.Fl d
switch to
.Xr find 1 .
Please note that using
.Fl depth
means you cannot prune a directory with
.Ic continue
as it will be processed after its children.
.It Fl ignoreErrors
Causes
.Ic fs-traverse
to ignore any permissions/read errors encountered during processing.
.It Fl tails
Returns paths relative to the top-level directory being traversed, as opposed to
absolute paths. When
.Fl tails
is used
.Va target-list
can contain only one item.
.It Fl --
Ignores any further flags and interprets the next parameter as
.Va varname
even if it begins with a dash.
.El
.Pp
If
.Nm fs-traverse
is called directly on a symbolic link, the link will be followed.
All other links encountered during traversal will not be followed.
.Pp
.Nm fs-traverse
will not descend into directories that have a different device number than
the root of the descent.
.Pp
If you remove the current directory during traversal, be aware that you must call
.Nm continue
to inform
.Nm fs-traverse
that the directory should not be descended into.
.It Xo
.Ic curl fetch

.Op Cm home Ns = Ns Ar home
.Op Cm shell Ns = Ns Ar shell
.Xc
Add a new local user to the system with the specified uid, gid, password, real
name, home directory and login shell.
Note that it is usually preferable to set the
.Ic add_users
option rather than call adduser directly, since it may need to be called in
multiple places to handle all cases (e.g., installing from a binary archive).
.It Ic existsuser Ar username
Check if a local user exists.
.It Ic nextuid
Returns the highest used uid plus one.

.Dl addgroup foo
.Dl adduser foo gid=[existsgroup foo]
.It Ic nextgid
Returns the highest used gid plus one.
.It Xo
.Ic reinplace
.Op Fl E
.Ar regex
.Ar
.Xc
