Praat Script Tips †
Emulation of Perl's split function †
- The subscripts start at 0.
- The last subscript is stored in lastSub.
- delimiter$ is specified by a regular expression.
string$ = "hoge/piyo/foo/bar"
delimiter$ = "/"
if index_regex("",delimiter$) = 1
lastSub = length(string$)-1
for i from 0 to lastSub
arr$[i] = mid$(string$,i+1,1)
endfor
else
lastSub = 0
arr$[lastSub] = string$
repeat
lastValue$ = arr$[lastSub]
delimiterPos = index_regex(lastValue$,delimiter$)
if delimiterPos <> 0
arr$[lastSub] = left$(lastValue$,delimiterPos-1)
lastSub = lastSub+1
arr$[lastSub] = replace_regex$(right$(lastValue$,length(lastValue$)-delimiterPos+1),delimiter$,"",1)
endif
until delimiterPos = 0
endif
clearinfo
for i from 0 to lastSub
hop$ = arr$[i]
printline 'i''tab$''hop$'
endfor
0 hoge
1 piyo
2 foo
3 bar
- Cf. An equivalent Perl Script:
$string = "hoge/piyo/foo/bar";
$delimiter = "/";
@arr = split(/$delimiter/,$string);
for ( $i = 0 ; $i <= $#arr ; $i++ ) {
print "$i\t$arr[$i]\n";
}
Get the path separator for your platform †
- Get the path separator for your platform, and
- Rewrite the path.
- Useful especially if you use Cygwin.
input$ = "c:/foo/bar/hoge.TextGrid"
output$ = "c:/foo/bar/result"
#input$ = "c:\foo\bar\hoge.TextGrid"
#output$ = "c:\foo\bar\result"
if windows = 1
pathSep$ = "\"
notPathSep$ = "/"
elsif macintosh + unix >= 1
pathSep$ = "/"
notPathSep$ = "\"
else
exit Sorry. Unknown platform.
endif
input$ = replace$(input$,notPathSep$,pathSep$,0)
output$ = replace$(output$,notPathSep$,pathSep$,0)
clearinfo
printline 'input$'
printline 'output$'
- Result (using Windows Praat on Cygwin):
c:\foo\bar\hoge.TextGrid
c:\foo\bar\result
Get the path and filename from a string †
dir$ = "c:/hoge/piyo/foo.TextGrid"
#dir$ = "c:\hoge\piyo\foo.TextGrid"
if windows + macintosh + unix = 0
exit Sorry. Unknown platform.
endif
path$ = left$(dir$,rindex_regex(dir$,"[/\\]"))
filename$ = right$(dir$,length(dir$)-rindex_regex(dir$,"[/\\]"))
## if you have the path separator (pathSep$) already, you can write:
#path$ = left$(dir$,rindex(dir$,pathSep$))
#filename$ = right$(dir$,length(dir$)-rindex(dir$,pathSep$))
clearinfo
printline 'path$'
printline 'filename$'
c:/hoge/piyo/
foo.TextGrid
Upper to Lower Case †
str$ = "ABCDEFG"
newstr$ = replace_regex$(str$,"[A-Z]","\L&",0)
echo 'newstr$'
abcdefg
Get the tiernumbers from tiernames †
- If you already know the names of the target tiers (e.g., "Seg," "Word"), ...
file$ = "N:\sample\sample.TextGrid"
Read from file... 'file$'
segTierNum = 0
wordTierNum = 0
n = Get number of tiers
for i from 1 to n
currentTier$ = Get tier name... i
if currentTier$ = "Seg"
segTierNum = i
elsif currentTier$ = "Word"
wordTierNum = i
endif
endfor
if segTierNum = 0
exit Seg tier not found in 'file$'
elsif wordTierNum = 0
exit Word tier not found in 'file$'
endif
clearinfo
printline Seg tier: 'segTierNum'
printline Word tier: 'wordTierNum'
Recover the previous state of Object List †
# Before trying this script, make several objects
# on the Object List and select some of them.
selectedObjectNum = numberOfSelected()
for i from 1 to selectedObjectNum
selectedID[i] = selected(i)
endfor
select all
pause All objects are selected. Press "Continue" to recover the previous state.
if selectedObjectNum <> 0
select selectedID[1]
for i from 2 to selectedObjectNum
plus selectedID[i]
endfor
endif
