NAME

porttree — Show dependences of a FreeBSD port as a pseudo graphical tree

SYNOPSIS

DESCRIPTION

The porttree utility is a tool for visualizing dependences of a port, and ports dependent on the given ports. All known types of dependences are tracked and shown after the portname in parenthesis by the first character of the type name. E.g. if a port is needed to patch and to build, its name will be followed by "(BP)".

The list of known types is BUILD, EXTRACT, FETCH, PATCH, LIB, RUN, TEST. The PKG type is not tracked by porttree, yet.

If no category/port portname is given, porttree will try to use the current directory. Portnames are to be given either as full pathnames or as category/port within the portsdir, or else as a pattern for package names. In the results, the portsdir is removed from the beginning of the full pathnames. In case of package name pattern, the given string is passed to pkg-info(1) along with switches -qo and all resulting origins of the corresponding installed packages are used in place of the pattern.

Use style 0 on a terminal without pseudo graphic chars (e.g. ISO-8859-15), or switch the encoding of the terminal to utf-8, cp855, or similar. E.g. gnome-terminal(1) allows to choose the encoding.

OPTIONS

-C | --color

Use ANSI color (or underlining) codes for characters indicating the dependence types to ease visual tracking.

-c config | --config config

Read configuration settings from file config after the default files /usr/local/etc/porttree.conf and .porttree.conf in user's home directory.

-D | --no-depends

Do not show direct depends. Implies -r.

-i | --cache

Ignore ports system updates, unconditionally use cached information. Implies that cache is not written back.

-n | --number-all

Number all lines of the output, even the lines with reference to previously shown ports. By default, this lines are not numbered, thus the biggest line number indicates the total number of dependences.

-O | --others

After the dependences of the given ports are shown, show also the not previously shown ports with their dependences.

-P portsdir | --portsdir portsdir

Use the given directory portsdir to find the ports instead of the default /usr/ports.

-q | --quiet

Do not show a category name before scanning it. The names are shown as the scan progress indicator.

--no-quiet

Unset the quiet mode set in config files. Do not use this option in config files.

-r | -R | --reverse

Show reversed dependences, i.e. show ports depending on the given one. -R is deprecated and will be removed soon.

-s st | --style st

Use pseudo graphic chars style st. Few styles are defined at the moment:

-1

- check for availability of Alternative Character Set (ACS) in termcap/terminfo capabilities of the terminal where the program is running and use it or fall back to the ASCII-only mode. This part was written with help from Oliver Fromme.

0

- use usual chars only (like ‘|’, ‘`’, and ‘+’).

1

- single line pseudo graphics. For a previously shown port name, add after the name an arrow ‘->’ with the line number where it was shown. Also, a branching to nowhere symbol is added before the port name, if it has further dependences.

2

- same as 1, but use double line pseudo graphics.

3

- (default) same as 1, but no indication of branching for previously shown ports. Also, the arrow after a previously shown port name is a pseudo graphical unicode symbol with no correspondent symbols in other encodings. This causes problems when recoding the output with iconv(1).

4

- same as 3, but use double line pseudo graphics. The double arrow might cause recording problems, as in 3.

5

- unconditionally use ACS pseudo graphics of xterm/vt100 terminal.

-S filename | --save filename

Save the interdependences data to the file filename. Defaults to /var/tmp/porttree.cache.

-U filename | --use-saved filename

Read the interdependences data from the file filename. An empty string as filename forces to skip reading saved data. Defaults to /var/tmp/porttree.cache.

EXAMPLES

The following are examples of typical usage of the porttree command:

All dependences and dependents of gcc, and save the data for future use in the file cache rather than default file:

AUTHORS

The program and this manual page were written by Vladimir Chukharev.

BUGS

Styles 3 and 4 use arrow chars which could not be converted by iconv(1) to console charsets (e.g. cp437).

PKG type of dependence is not tracked.

There is no protection for concurrent execution.

Some options set in a config file cannot be unset in command line.
