Stata Tip

Getting Stata to automatically open a web page

Sometimes there are Web pages that you would like to access every now and then. For example Stata's forthcoming web page (you can sign up for email updates but writing a program is more fun) or Stata blogs etc.

Below is a way that this might be done. You could turn this into a ado file or just put it into your profile.do

The time interva1 (macro t), in days, is specified at comment 8 below.


clear mata

local a : sysdir PERSONAL                                   //1
cd `a'

mata:                                                       //2
if(!fileexists("mymatrix")){                                //3
  v=st_global("c(current_date)")                            //4
  X=date(v,"DMY")                                           //5

  fh = fopen("mymatrix.myfile", "rw")                       //6
  fputmatrix(fh, X)
  fclose(fh)
}

fh = fopen("mymatrix.myfile", "rw")                         //7
X = fgetmatrix(fh)
fclose(fh)

st_local("date",strofreal(X))

end  //end mata

local t=1  //interval                                       //8

if `date'+`t'< date(c(current_date),"DMY") {                //9 
  shell "C:\Program Files\Mozilla Firefox\firefox.exe" ///
		"http://www.stata-press.com/forthcoming/"           //10
}
else {
 display "No required to check web page"                    //11   
}

exit

Note on the above:
(1) Extended macro saving the path of Stata's PERSONAL location in the local macro a. PERSONAL is on Stata's adopath
(2) Using a Stata Mata matrix to store the date that a Web page was last accessed. You could store the information in other forms but a Mata matrix seemed a handy way of doing this
(3) The first time that this is run there is no Mata file; so just checking if one needs to be created. If not, jump into the loop
(4) Save the current date in a scalar matrix called v
(5) Convert current date to Stata elapsed time using the date() function
(6) Saving the Mata matrix to a file
(7) Reading the saved Mata file
(8) Save the interval (days) that you wish to display the web page. In this case every day
(9) If the duration that the web page was last accessed is greater then the specified interval and it has not been accessed today then jump into loop
(10) The web page that you wish to see
(11) Comment indicating that program is working but is not required to access Web page
