Formatting Functions For Time/Date

Difference between version 2 and 3 - Previous - Next
Created by [CecilWesterhof].

I created some procs to easily get some date/time formats.

The first is because I miss the %F format in clock.


======
# Clock format which recognises %F
proc clockFrmt {time format} {
    clock format ${time} -format [string map {%F {%Y-%m-%d}} ${format}]
}
======

But I find it also handy as a shorter form for clock with format. ;-)
I want as default the current time. This is not really possible. That is why I use -1 as default and created a function to convert the -1:--
I want as default the current time. This is not really possible. That is why I use NOW as default and created a function to convert the NOW:

======
# When a proc has no value for thisTime convert it to current time.
proc convertDefaultTime {thisTime} {    if {${thisTime} == -1NOW} {
        return [clock seconds]
    }
    return ${thisTime}
}

[Martyn Smith] For me I would use the default value NOW and not -1 it makes the code easier to read.
Done, thanks for the tip.

Then I created the following three procs.


======proc getDateStr {{thisTime -1NOW}} {
    set thisTime [convertDefaultTime ${thisTime}]
    clockFrmt ${thisTime} "%F"
}
proc getDateTimeStr {{thisTime -1NOW}} {
    set thisTime [convertDefaultTime ${thisTime}]
    clockFrmt ${thisTime} "%FT%T"
}
proc getTimeStr {{thisTime -1NOW}} {
    set thisTime [convertDefaultTime ${thisTime}]
    clockFrmt ${thisTime} "%T"
}
======

An example usage:

======
proc showMessage {message {onlyTime False} {display True}} {
    if {${display}} {
        if {${onlyTime}} {
            set moment [getTimeStr]
        } else {
            set moment [getDateTimeStr]
        }
        puts [format "%s: %s" ${moment} ${message}]
    }
}
======
