This Android never suffered Pteronophobia (the fear of being tickled by feathers!)

tclODBC + tclhttpd

JM 22 Jul 2011 - I was just playing a little bit with tclhttpd by putting the following code on the file: \htdocs\cgi-bin\test.cgi

 package require tclodbc
 set driver "Microsoft Access Driver (*.mdb)"
 set dbfile "C:\\Program Files\\Microsoft Office\\office11\\samples\\Northwind.mdb"

 puts [html::h3 "getting info from Access through tclODBC..."]
 puts "<table border=1 cellpadding=4>"
 database connect db "DRIVER=$driver;DBQ=$dbfile"

 foreach rec [db "select EmployeeID,LastName,FirstName FROM Employees;"] {
   puts "<tr>"
   foreach field $rec {
     puts "<td>$field</td>"
   }   
     puts "</tr>"
 } 
 puts "</table>" 
 db disconnect

just after the following existing lines:

 puts [html::h1 "Hello, World!"]
 puts [html::h2 [clock format [clock seconds]]]

and I got a dynamic page that queries the database that comes as a sample with the Microsoft Access installation.

you can get there by means of the CGI link on the home page, then through the Sample form posted to test.cgi and finally hitting the "Submit Query" button.

pscp

JM 7 Sep 2013 - pscp from the putty family of tools, see also plink

  • The following script runs on a windows machine
  • Getting a file from an ubuntu machine
  • The file will be copied to c:\putty in this case
 console show
 proc action {} {
   cd c:/putty
   set f [open "|\"pscp.exe\" -l jorge -pw yourpwd [.from get]:[.path get] ."]
   puts done
 }
 entry .from
 entry .path -width 50
 button .button -text get -command action

 .from insert 0 [email protected]
 .path insert 0 /home/jorge/sample.txt

 pack .from .path .button

gnuplot and the tkcanvas terminal type

JM 26 Oct 2013 - I dont know why, but I had to put some puts commands after the source command to make it work, if not, I was getting an error saying that the gnuplot commmand did not exist

 console show
 #set gpexe C:/gnuplot-4.0/bin/pgnuplot.exe
 set gpexe "C:/Program Files (x86)/gnuplot/bin/pgnuplot.exe"
 #set outfile C:/data/resultat.tk
 set outfile "C:/Users/jmoreno/Documents/code/gnuplot/resultat.tk"

 set gp [open "|\"$gpexe\"" r+]
 puts $gp "set term tk"
 puts $gp "set output '$outfile'"
 puts $gp "set noborder\nset zeroaxis"
 puts $gp "set xtics 1\nset ytics .5"
 puts $gp "plot \[-2:2\] atan(x)"
 close $gp

 pack [canvas .c]
 source $outfile
 puts $outfile
 puts [info commands gnu*]
 update
 gnuplot .c

JM 7 Nov 2014 - Looks like the real fix is this (just waiting a little, to let pgnuplot.exe to completely close):

 console show
 #set gpexe C:/gnuplot-4.0/bin/pgnuplot.exe
 set gpexe "C:/Program Files (x86)/gnuplot/bin/pgnuplot.exe"
 #set outfile C:/data/resultat.tk
 set outfile "C:/Users/jmoreno/Documents/code/gnuplot/resultat.tk"

 set gp [open "|\"$gpexe\"" r+]
 puts $gp "set term tk"
 puts $gp "set output '$outfile'"
 puts $gp "set noborder\nset zeroaxis"
 puts $gp "set xtics 1\nset ytics .5"
 puts $gp "plot \[-2:2\] atan(x)"
 close $gp
 after 1000
 pack [canvas .c]
 source $outfile
 #puts "we are at: [pwd]"
 #puts $outfile
 #puts [info commands gnu*]
 #update
 gnuplot .c

Expect

JM 18 Feb 2014 - The following example was good for me to try the basics

Other scripts that need some polishing

extract images from pdf

JM 20 Nov 2020 - This is mostly code from miniMu

package require mupdf
console show

set pdfFileName [tk_getOpenFile -filetypes {{Pdf .pdf}}]
set pdf [mupdf::open $pdfFileName]

set pageQty [$pdf npages]
for {set i 0} {$i < $pageQty} {incr i} {
        set page [$pdf getpage $i]   ;# 0 is the 1st page
        set ctr 0
        foreach imagen [$page images list] {
                puts $imagen
                set id [$page images extract -id [lindex $imagen 0] -as "img$i-[lindex $imagen 1]"]
                incr ctr

}
