Abstract Package Name (for install/uninstall command)
There are several different ways of referring to a package that Pyrus and the
PEAR Installer understand. Three ways are concrete, in that they refer to
deterministic entities such as a package.xml file on disk, or a URI
(Uniform Resource Identifier) such as http://pear.php.ne/get/PEAR-1.8.1.tgz
that refers to a file on a remote server.
| Package type | Local/Remote | Пример |
|---|---|---|
package.xml file |
Local | php pyrus.phar install /path/to/package.xml |
| Package release archive | Local | php pyrus.phar install /path/to/PackageName-1.2.3.tgz |
| Static url | Remote | php pyrus.phar install http://example.com/PackageName-1.2.3.tgz |
| Abstract package | Remote | php pyrus.phar install PackageName |
The first three ways of specifying a package are concrete: the package name
always refers to one and only one package. Abstract packages are more
flexible, and there are several ways of requesting a package. Note that
if the channel is not explicitly requested (as it is in the last example),
Pyrus or the PEAR Installer prepends the default channel. The default channel
is set by the default_channel configuration variable, and is
set to one of pear.php.net (pear command), pecl.php.net
(pecl command), or pear2.php.net (Pyrus) unless explicitly changed
by a call to the config-set
(pear/pecl command) or set (pyrus)
command. A request for
PackageName will be interpreted by the PEAR Installer or Pyrus
to be a request for package PackageName from the default channel, as if the user had
requested pear.php.net/PackageName (pear command),
pecl.php.net/PackageName (pecl command) or
pear2.php.net/PackageName (pyrus).
| Пример | Описание |
|---|---|
PackageName-1.2.3 |
This forces Pyrus to download version 1.2.3 of
package PackageName, but will will attempt to download
a release in one of the following file formats, in this order:
|
PackageName-alpha |
This causes Pyrus to download the latest version of
package PackageName that is alpha
stability or better (the hierarchy of stabilities is devel,
alpha, beta, stable).
After finding a matching version, it will attempt to download a release
in one of the following file formats, in this order:
|
PackageName |
This causes Pyrus to download the latest version of
package PackageName that is preferred_state
(configuration variable)
stability or better (the hierarchy of stabilities is devel,
alpha, beta, stable).
After finding a matching version, it will attempt to download a release
in one of the following file formats, in this order:
preferred_state configuration variable can be seen
with the config-show
command.
|
PackageName#groupname |
This causes Pyrus to download and install a release of Pyrus as specified
above, and it also causes Pyrus to download and install the contents
of the groupname dependency group (dependency groups
are documented here).
Note that PackageName in PackageName#groupname
can be any of the above examples, such as PackageName-1.2.3#groupname.
|
channelname/PackageName |
This causes Pyrus to download and install a release of
PackageName from the channel channelname.
Another syntax that can be used is channel://channelname/PackageName
which is useful if there is a sub-directory of the current working
directory named channelname and a file or directory
within it named PackageName. Note that
in the example above, PackageName can be any of the
previous syntaces such as channelname/PackageName-1.2.3#groupname.

Abstract Package for installed packages
Note that the uninstall, run-scripts,
and other commands that operate on installed packages
only support a simple
package name as in PackageName or
channelname/PackageName. Any fancy stuff like
pear2.php.net/PackageName-1.2.3#group is ignored.
