Basic Defintion
Basically, hash tables are like ini files, storing information in following format:
Tablename
item1=data1
item2=data2
...
However, hash tables are a lot faster than ini- or text-files, which especially takes effect if you have a lot of entries. A kind of disadvantage is the missing possibility to see all entries. With some files, you can just open them and take a look on every entry, whereat hash table, you can't just open then. To have the chance to still get an overview, you can use the following script:
; lets make a little alias called showhash. At the end, it will look like /showhash <name>
alias showhash {
; echo the name and a kind of "table header"
echo -a $1
echo -a item => data
var %i = 1
; lets loop through all items. $hget($1,0).item will return the total amount of items.
while (%i <= $hget($1,0).item) {
echo -a $hget($1,%i).item => $hget($1,%i).data
; increase looping-variable
inc %i
}
}
Modifying hash tables
You can make a new hashtable using the /hmake, respectivly delete one using the /hfree command. Using /hdel and /hadd, you can modify the data saved in your hashtable. Due to hash tables not being automatically saved, you have to use the /hsave and /hload command.
Receiving data
After saving data in hash tables, you can of course receive them. Therefor, use the $hget and $hfind identifiers.
