The platform package provides several utility commands
useful for the identification of the architecture of a machine
running Tcl.
Whilst Tcl provides the tcl_platform array for
identifying the current architecture (in particular, the platform
and machine elements) this is not always sufficient. This is
because (on Unix machines) tcl_platform reflects the values
returned by the uname command and these are not standardized
across platforms and architectures. In addition, on at least one
platform (AIX) the tcl_platform(machine) contains the CPU
serial number.
Consequently, individual applications need to manipulate the
values in tcl_platform (along with the output of system
specific utilities) - which is both inconvenient for developers,
and introduces the potential for inconsistencies in identifying
architectures and in naming conventions.
The platform package prevents such fragmentation - i.e.,
it establishes a standard naming convention for architectures
running Tcl and makes it more convenient for developers to identify
the current architecture a Tcl program is running on.
- platform::identify
- This command returns an identifier describing the platform the
Tcl core is running on. The returned identifier has the general
format OS-CPU. The OS part of the identifier
may contain details like kernel version, libc version, etc., and
this information may contain dashes as well. The CPU part
will not contain dashes, making the preceding dash the last dash in
the result.
- platform::generic
- This command returns a simplified identifier describing the
platform the Tcl core is running on. In contrast to
platform::identify it leaves out details like kernel
version, libc version, etc. The returned identifier has the general
format OS-CPU.
- platform::patterns
identifier
- This command takes an identifier as returned by
platform::identify and returns a list of identifiers
describing compatible architectures.
