Texttools dot tcl
Recently I read Hillel Wayne's article about his texttools.py implementation.
I also looked into Tcl a bit. So what better way than to combine these too and port his Python implementation (which was already using Tk) to Tcl (and Wish). The functionality is simple: Paste text in the top box, choose a transform, output appears in the bottom box.
The full implementation is a mere 60 lines of Tcl:
#!/usr/bin/env wish
package require textutil
set active_transform 0
proc oneline {text} {
return [regsub -all \n+ $text " "]
}
proc wordcount {text} {
set lines [expr [llength [split $text \n]] - 1]
set words [llength [regexp -all -inline {\S+} $text]]
set len [string length $text]
lappend out $lines
lappend out $words
lappend out $len
return $out
}
proc dedent {text} {
return [textutil::undent $text]
}
proc markdown_quote {text} {
set text [string trim $text]
return [string cat "> " [regsub -all \n $text "\n> "]]
}
proc identity {text} { return $text }
lappend transforms [list {None} identity]
lappend transforms [list {One line} oneline]
lappend transforms [list {Line/Word/Char} wordcount]
lappend transforms [list {Dedent} dedent]
lappend transforms [list {Markdown Quote} markdown_quote]
