Need to regenerate all html's in a given directory

Hi

Need your input on the following

Task) Need to regenerate all html's in a given directory(including sub directory's) whenever the user previews or generates any one DCR.

Let me explain in a bit more detiled manner

say you have two dcr a.dcr and b.dcr and one common.tpl , now you generate two pages from a.dcr say a1.html and a2.html .


Now after generating a1.html and a2.html from a.dcr we make more changes to the dcr and saves it without regenaring.



Now we open the second dcr b.dcr and generate/preview the page. Now while the user is previewing/genating using the second b.dcr we need to regenarte all the pages generated using the first dcr as well.




This is the Solution which i wrote inside the tpl)

@files_list= system(" ls -R "Full path of the directory " | grep /");
foreach $k ( @files_list)
{
$k=~ s/://g;
chomp($k);
$k=$k."/*.html";
$cmd="$iwhome/bin/iwregen $k";
`$cmd`;

}


Issue ) The above code works, But the problem is the page dosent load easily, The time taken to preview or generate a page is very high. The given directory has around 100 test pages. most of the time when i try to preview the page it waits and waits till it finally times out.

BTW this code need to work on solaris / and not on windows ,so we have the liberty of writing system(ls ...);
Any suggestions ?

Hi

The first thought I had when I read your problem is that you probably want to take about 3 large steps back and rethink what you are trying to do here. Obviously I don't understand your business need to be regenerating pages, but it is something you probably don't want to be doing all the time.

That said, it appears you problem could be simplified if you could ensure that all generated files were always to up to date with the DCR they are based upon.

Have you considered some FormAPI to help you with this?

How about an event handler on onSaveDone. This could callServer and run a script which regenerates all the html files which were generated using this DCR. You could then be sure that all generated html pages were 'in sync' with their DCR. (You will need to keep track of what pages have been generated from the DCR -- there are a number of ways of doing this that have been discussed on the forum previously).

This would then avoid needing to regenerate 'everything' every time you want to preview.

btw: when using perl it is generally good practice to avoid system() calls when a perl module/command is available to do the same thing. Then your code can be cross-platform (just in case!).
