@time removing colons from the strinf

[Manny Zachodin]

The format of @time is   HH:MM:SS.  How can I convert the format to HHMM (without the colon).

Here’s one method:

tcl>echo $t

10:35:36

tcl>regsub -all — “:” $t {} newT

2

tcl>echo $newT

103536

tcl>set newT [csubstr $newT 0 4]

tcl>echo $newT

1035

tcl>

andanother…a little more cryptic…

tcl>echo $t

10:35:36

tcl>regsub -all — “:” [csubstr $t 0 5] {} newT

1

tcl>echo $newT

1035

Can I invoke this small routine in xlate?

Manny,

Here is another:

set whatsis [string map {: “”} “10:25:30”]

echo $whatsis

102530

The string command is finding more favor these days since (according to Charlie Bursell and the other Tcl wizards) string is highly optimized.

I also find many of the string commands easier to use.

Oh and you can do this in an Xlate.

I prefer not to imbed the code directly but rather invoke an external xltp type proc. This allows me to construct reusable code and eliminates the annoyance of when I misplace a curly brace or square bracket and get debug information which gives me everything I don;t want to know about the Xlate and always seems to stop short of telling me where in my code Tcl had objections.

Mos timportant to me is the reusable code. Then the next time I need to do a string map, I just change the arguments to the proc. Non Tcl proficient folks can use the facility as well.
