NAME
platform::shell - System identification support code and utilities
SYNOPSIS
package require platform::shell ?1.1.4?
platform::shell::generic shell
platform::shell::identify shell
platform::shell::platform shell
______________________________________________________________________________
DESCRIPTION
The platform::shell package provides several utility commands useful
for the identification of the architecture of a specific Tcl shell.
This package allows the identification of the architecture of a spe-
cific Tcl shell different from the shell running the package. The only
requirement is that the other shell (identified by its path), is actu-
ally executable on the current machine.
While for most platform this means that the architecture of the inter-
rogated shell is identical to the architecture of the running shell
this is not generally true. A counter example are all platforms which
have 32 and 64 bit variants and where a 64bit system is able to run
32bit code. For these running and interrogated shell may have different
32/64 bit settings and thus different identifiers.
For applications like a code repository it is important to identify the
architecture of the shell which will actually run the installed pack-
ages, versus the architecture of the shell running the repository soft-
ware.
COMMANDS
platform::shell::identify shell
This command does the same identification as platform::identify,
for the specified Tcl shell, in contrast to the running shell.
platform::shell::generic shell
This command does the same identification as platform::generic,
for the specified Tcl shell, in contrast to the running shell.
platform::shell::platform shell
This command returns the contents of tcl_platform(platform) for
the specified Tcl shell.
