The /hinc command increases the value of a hashtable item by [num]. If the optional number value is not specified, the default value is 1.0. It uses the same syntax as /hadd except it does not support the -b switch recognizing item values as being binary variables.
Synopsis
/hinc [-m[N]szuNk] <table> <item> [num]
Switches
- -m[N] - Creates the hash table if it does not exist, optionally setting the number of buckets to N. (Valid N 1-10000)
- -s - Displays the assignment information
- -z - After setting the data's value, decreases the value by 1.0 each second; unsets to prevent the data value being zero or negative
- -uN - Removes the hashtable item/value after N seconds
- -k - Keep the existing unset delay while altering the existing data value
Note: If hashtable item has non.zero $hget(table,item).unset property due to being created or modified by -uN or -z switch when created or modified with /hinc /hdec or /hadd, then /hsave will not save that item to disk without the /hsave -u switch.
Parameters
- <table> - The handle name of the table containing the 'item'
- <item> - The item name associated with the data value
- [num] - The optional value by which to increase the data value. If not present, increases by 1.0
Example
Example 1:
alias example { ;create the table hmake -s example ;add a few items hadd example item1 4 hadd example item2 7 hadd example item3 9 ; print the items echo -a item1 = $hget(example, item1) echo -a item2 = $hget(example, item2) echo -a item3 = $hget(example, item3) ; increase the values hinc example item1 5 hinc example item2 12 hinc example item3 1 echo -e - ; print the items echo -a item1 = $hget(example, item1) echo -a item2 = $hget(example, item2) echo -a item3 = $hget(example, item3) ;cleanup hfree -s example }
A counter example:
alias countup { ;adds the item up with a value of 0 to the table count hadd -m count up 0 echo -a $hget(count,up) $+ ! :repeat ;checks if the value of down returns true if ($hget(count,up) < 9) { ;increases down by 1 hinc count up ;echos the current count echo -a $hget(count,up) $+ ! ;repeats goto repeat } ;if the previous if statement returns false it carries on with this. else echo -a 10, done! hfree -s count }
//hfree -sw test | hinc -sm test foo 5 | echo -a item foo has value $hget(test,foo) Result: 5 * If the item does not exist, /hinc behaves as if the item exists with a value of zero. //hfree -sw test | var %a 0 | hadd -sm test foo 5 | hinc test foo %a | echo -a item foo has value $hget(test,foo) Result: 5 //hfree -sw test | var %a | hadd -sm test foo 5 | hinc test foo %a | echo -a item foo has value $hget(test,foo) Result: 6 * If variable used to increment the item is $null the increment is the default 1. //hfree -sw test | hadd -sm50 test foo 9.123456789 | echo -a item foo has value $hget(test,foo) | hinc -s test foo 2 | echo -a item foo has value $hget(test,foo) * While a hash table value can be created having more than 6 decimals, the result of /hinc is rounded to nearest 6 decimals, the same result as if $calc(old_value + increment_value). If the [num] parameter is incorrectly set to be non-numeric, the item is unset 1 second later because $calc(string - 1) is zero. //hfree -sw test | hadd -sm50 test foo 30 | echo -a item foo has value $hget(test,foo) | hinc -sz test foo 50 | echo -a item foo has value $hget(test,foo) and will unset in $hget(test,foo).unset secs * After the value has been incremented, -z begins with the incremented value then decreases it once per second, but also gives the item the characteristic as if -u2147483647 were also used. (2^31-1) //hfree -sw test | hadd -sm50 test foo 30 | echo -a item foo has value $hget(test,foo) | hinc -szu30 test foo 50 | echo -a item foo has value $hget(test,foo) and will unset in $hget(test,foo).unset secs * Same as above, except -u30 modifies the future unset time to be 30 seconds instead of 2147483647. //hfree -sw test | hadd -sm50u30 test foo 30 | echo -a item foo has value $hget(test,foo) | hinc -k test foo 50 | echo -a item foo has value $hget(test,foo) and will unset in $hget(test,foo).unset secs * -k preserves the existing future unset time of the hashtable item, and has no effect if the item hadn't been created using the -uN or -z switches. * Note: Any data value created or modified using the -z or -uN switch has the characteristic of being unset in the future, and /hsave will not save that item/data pair to disk unless the /hsave -u switch is used. //hfree -sw test | hinc -smzu10 test foo 30.4 | .timer 11 1 echo 4 -a value $!hget(test,foo) vs .unset $!hget(test,foo).unset //hfree -sw test | hinc -smzu10 test foo 5.44 | .timer 11 1 echo 4 -a value $!hget(test,foo) vs .unset $!hget(test,foo).unset * When item is created using both -z and -uN, the variable is unset to prevent the first of either .unset seconds reaching zero or the value decrements to be zero or negative.
