Functions
- clone (t, nometa)
-
Make a shallow copy of a table, including any metatable (for a deep copy, use tree.clone).
Parameters
- t: table
- nometa: if non-nil don't copy metatable
Return value:
copy of table - empty (t)
-
Return whether table is empty.
Parameters
- t: table
Return value:
trueif empty orfalseotherwise - indices (t)
-
Make the list of indices of a table.
Parameters
- t: table
Return value:
list of indices - invert (t)
-
Invert a table.
Parameters
-
t: table
{i=v, ...}
Return value:
inverted table{v=i, ...} -
t: table
- merge (t, u)
-
Merge two tables. If there are duplicate fields, u's will be used. The metatable of the returned table is that of t.
Parameters
- t: first table
- u: second table
Return value:
merged table - new (x, t)
-
Make a table with a default value for unset keys.
Parameters
-
x: default entry value (default:
nil) -
t: initial table (default:
{})
Return value:
table whose unset elements are x -
x: default entry value (default:
- rearrange (m, t)
-
Rearrange some indices of a table.
Parameters
-
m: table
{old_index=new_index, ...} - t: table to rearrange
Return value:
rearranged table -
m: table
- size (t)
-
Find the number of elements in a table.
Parameters
- t: table
Return value:
number of elements in t - sort (t, c)
-
Make table.sort return its result.
Parameters
- t: table
- c: comparator function
Return value:
sorted table - values (t)
-
Make the list of values of a table.
Parameters
- t: table
Return value:
list of values
