in reply to replacing "dynamic" variables

Update2: Also, you might want to look into one of the various Config or templating modules (such as Template-Toolkit), as it sounds like you might be trying to roll your own basic templating system.

$line =~ s[ \$ # Dollar sign (literal) { # Open brace (literal) ( # capture (into $1) [^}]+ # One or more non-close brace characters ) # end capture } # Close brace (literal) ][$dynamic_variables{$1}]xg;

Update: Expanded regexp with /x

[stevieb]: atcroft: "Make both hands into fists..."... is something my Ma taught me in our native lang, but I was to ignorant and young to pay attention. Thanks for that :)
[atcroft]: stevieb: Sad to say that I only recently learned that particular trick, but I have since found it very useful.... :)
[james28909]: ill be back with a solution eventually
[stevieb]: it's a reminder to re-inforce it :P
[atcroft]: james28909: That particular questions was a bit of trick, actually (depending on the country you are in). More interesting is, if you are trying to subtract from an epoch time, for instance, you might have to consider when/if DST occurs for a location,
[atcroft]: because you may have to adjust the number of seconds you change from an epoch from 86400 (not to mention leap seconds)....
[atcroft]: james28909: Although if your program is using a database, you might be able to "pass the buck" to the database and ask it to do the date change for you....
