24 | .SH DESCRIPTION |
---|
25 | .PP |
---|
26 | The \fBplatform::shell\fR package provides several utility commands useful |
---|
27 | for the identification of the architecture of a specific Tcl shell. |
---|
28 | .PP |
---|
29 | This package allows the identification of the architecture of a |
---|
30 | specific Tcl shell different from the shell running the package. The |
---|
31 | only requirement is that the other shell (identified by its path), is |
---|
32 | actually executable on the current machine. |
---|
33 | .PP |
---|
34 | While for most platform this means that the architecture of the |
---|
35 | interrogated shell is identical to the architecture of the running |
---|
36 | shell this is not generally true. A counter example are all platforms |
---|
37 | which have 32 and 64 bit variants and where a 64bit system is able to |
---|
38 | run 32bit code. For these running and interrogated shell may have |
---|
39 | different 32/64 bit settings and thus different identifiers. |
---|
40 | .PP |
---|
41 | For applications like a code repository it is important to identify |
---|
42 | the architecture of the shell which will actually run the installed |
---|
43 | packages, versus the architecture of the shell running the repository |
---|
44 | software. |
---|
45 | .SH COMMANDS |
---|
46 | .TP |
---|
47 | \fBplatform::shell::identify \fIshell\fR |
---|
48 | This command does the same identification as \fBplatform::identify\fR, |
---|
49 | for the specified Tcl shell, in contrast to the running shell. |
---|
50 | .TP |
---|
51 | \fBplatform::shell::generic \fIshell\fR |
---|
52 | This command does the same identification as \fBplatform::generic\fR, |
---|
53 | for the specified Tcl shell, in contrast to the running shell. |
---|
54 | .TP |
---|
55 | \fBplatform::shell::platform \fIshell\fR |
---|
56 | This command returns the contents of \fBtcl_platform(platform)\fR for |
---|
57 | the specified Tcl shell. |
---|
58 | .SH KEYWORDS |
---|
