Pashua is a very very simple GUI builder for MacOSX scripting languages. The author (Carsten Bluem [L1 ]) has demos written in PHP, Perl, Python, sh and AppleScript. I hope to submit a Tcl wrapper and demo. As I'm a rank beginner with respect to Tcl, I'm posting my code here so that others more adept with Tcl can critique the code before submission.
#wrapper for Pashua in Tcl
#Bruce M. Axtens, 2004.
proc pashua_run {script} {
upvar #0 argv0 appName
upvar #0 env envir
set tempFile [exec /usr/bin/mktemp /tmp/Pashua_XXXXXXXX]
set handle [open $tempFile w]
puts $handle $script
close $handle
#search for Pashua binary
set bundlePath "Pashua.app/Contents/MacOS/Pashua"
set theHome $envir(HOME)
set theList [list "$appName/Pashua" \
"$appName/$bundlePath" \
"/$bundlePath" \
"./$bundlePath" \
"/Applications/$bundlePath" \
"$theHome/Applications/$bundlePath" ]
set theBinary ""
foreach possib $theList {
if {[file exists $possib]} then {
if {[file executable $possib]} then {
set theBinary $possib
break
}
}
}
if {$theBinary ne ""} {
set handle [open "|$theBinary $tempFile" r]
while {[eof $handle]==0} {
gets $handle theLine
set equals [string first {=} $theLine]
if {$equals > -1} {
array set results \
[list [string range $theLine 0 [expr $equals - 1]] \
[string range $theLine [expr $equals + 1] end]]
}
}
return [array get results]
} else {
return ""
}
}The following is a test script (test.tcl) based on Blüm's one for Perl. Any suggestions to make it more Tcl-ish? Make sure if you copy this code out to a file that you remove the indent as Pashua will treat " tcl_type" as " tcl_type" not "tcl_type".
