In LibreOffice Calc, you can use function REGEX for e.g.Begins with 'ph' will be =REGEX(A1,"ph")Ends in 'E' will be =REGEX(A1,"E$")

Although JavaScript regexes used to be underpowered compared to other modern flavors, numerous improvements in recent years mean that’s no longer true. Steven Levithan evaluates the history and present state of regular expressions in JavaScript with tips to make your regexes more readable, maintainable, and resilient.

Hi,

I have a string "[@global_vddi:%:vddi!]" which I need to process to remove "@[]" chars. The desired result is "global_vddi:%:vddi!". I tried the following in CIW

netExpr = "[@global_vddi:%:vddi!]"
rexCompile("\([a-zA-Z0-9_:!%]+\)")
t
rexExecute(netExpr)
t
rexSubstitute( "\0" )
"global_vddi:%:vddi!"

and I achieved the desired value. I added the same code to my script but it didn't work. In my script rexExecute returns 't' but rexSubstitute returns 'nil' 

Here is the snippet from my script

netExpr = dbGetTermNetExpr(term)
if(netExpr then
rexCompile("\([a-zA-Z0-9_:!%]+\)")
rexExecute(netExpr)
netExpr1 = rexSubstitute( "\0" )

...

. ..)  and trace log showing the variable values as the code executes

stopped before evaluating dbGetTermNetExpr(term)
after evaluating dbGetTermNetExpr(term)==> "[@global_vddi:%:vddi!]"
after evaluating (netExpr = dbGetTermNetExpr(term))==> "[@global_vddi:%:vddi!]"
stopped before evaluating if(netExpr then rexCompile("\([a-zA-Z0-9_:!%]+\)") rexExecute(netExpr) (netExpr1 = rexSubstitute("\0")) ... )
stopped before evaluating rexCompile("\([a-zA-Z0-9_:!%]+\)")
after evaluating rexCompile("\([a-zA-Z0-9_:!%]+\)")==> t
stopped before evaluating rexExecute(netExpr)
after evaluating rexExecute(netExpr)==> t
stopped before evaluating (netExpr1 = rexSubstitute("\0"))
stopped before evaluating rexSubstitute("\0")
after evaluating rexSubstitute("\0")==> nil
|[2]netExpr1 set to nil, was nil

Any help or suggestions as to why the code executes differently in CIW and when called from a SKILL script file will be much appreciated.

I also tried a different approach using rexReplace instead of rexSubstitute but couldn't get the regex pattern correct. The code I tried in CIW using rexReplace is as follows

a = "[@global_vddi:%:vddi!]"
"[@global_vddi:%:vddi!]"
rexCompile("\([@\[\]]*\)")
t
rexReplace(a "" 0)
"global_vddi:%:vddi!]"

Only '@[' get replaced and ']' is still present. The regex pattern contains '\]' to match the closing square bracket yet it is not replaced. Please let me know what I'm missing in these 2 scenarios.

Any help is much appreciated!!

Confused SKILL user 

Specman *search* command allows searching in all loaded modules, but only for a string.

Is there a way to search for a regexp or glob?

Alternatively, is there a way to simply get a list of all loaded files somehow? Then I could use either the "shell" command, or real shell together with grep.

Thanks
