| 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 |
|---|
