:container
入力: none
出力: none
A colon : indicates a container, with the name of the word following the colon. turtleSpaces 'resolves' a :container 'tag' into the value of that container when an instruction is executed, such that if the value of :container is 5, then forward :container becomes 'resolved' to forward 5, before the instruction is executed.
show :container
:=
入力: expression | expression
出力: none
Assigns the value of the second expression to the container name resolved by the first expression. See make for more details
So, for example, "frog := 5 puts the value 5 in the container named frog. However, :frog := 5 puts the value of 5 in the container named whatever is inside the container named frog.
"frog := "duck
:frog = 5
show :duck

make!
入力: name (word) | expression
出力: none
Contains a runtime-evaluated expression, or 'mutated' container. This allow expressions to be stored inside containers, and rather than being evaluated when stored, they are evaluated when recalled. A container that contains a REX may only contain a single REX and nothing else. See also name! and put!

pr :moo
make! "clock (se hours minutes seconds)

newdictionary "mydict
nopersist
入力: "name
出力: none
Stops persisting the container or table "name and removes it from storage. The container itself is left in place; use erase to get rid of it. See persist
nopersist "score
persist
入力: "name
出力: none
Indicates that the container or table "name should be stored and updated with the project and with the browser session, and reloaded with both. Persisted containers survive reset and resetall, but not loading or creating another project. See nopersist, share
persist "score
plist
入力: propertylistname (word)
出力: propertylist (list)
Outputs the property list associated with the supplied name. Any word can have a property list associated with it – a list of 'properties' and their values. plist returns a list of these pairs sequentially: [property1 value1 property2 value2 etc.] See pprop
show plist "propertylist
pon
入力: container(s) (word or list)
出力: none

See push
make "result pop "pushlist

出力: none
Property lists are a special type of container that hold multiple property / value pairs. You can have a property list and a non-property list container with the same name.
pprop "addresses [Marty McFly] [9303 Lyon Drive, Lyon Estates, Hill Valley CA 95420]
pps
入力: none
出力: none
Prints the property list containers belonging to the calling turtle.
pps
private
入力: word
出力: none
Initialises a private container with the name provided. A private container is a container which only exists and whose value persists inside of a procedure. This allows you to construct a procedure that modifies and stores internal parameters without losing them when that procedure exits, and needing to store them in the turtle. See the examples.

if not namep "frog [private "frog make "frog 1 stop]
inc "frog
show :frog
END

if :switch = "a [make "var 1]

END
put
入力: input (number, word, phrase, list, primitive or container) | in | name (word)

put! (se hours minutes seconds) in "clock
push
入力: item | container
出力: none
"Pushes" the item on to the front of the specified container, making it the first item, and pushing the rest of the items to the right. If the container contains a word, push pushes the item on to the start of the word. If the container contains a list, push pushes the item on to the front of the list. To pull the item out of the container, use pop. Also see queue and dequeue (which do similar but to the end of the container).
push "frog "animals
queue
入力: item | container
出力: none
Similar to push, except adds the provided item to the end of the container, appending it to the word or list inside it. See push
queue "item "container
remprop
入力: name | property
出力: none
Removes the given property from the named property list.
remprop "proplist "property
rename
入力: oldname | newname
出力: none
Renames a container.
rename "oldname "newname
retrieve
入力: database (word) | key (word)
出力: none
Restores the values of the containers stored in the given database under the given key using the store primitive. For example, if you stored the containers :ducks and :pigs under the key "animals, then retrieving "animals would restore the values of :ducks and :pigs to the values they had when they are stored. See newdatabase, store
retrieve "farm "livestock
(show :pigs :ducks :cows)
set
入力: surname | container | value
出力: none
Sets the contents of the named container in the named surname to the provided value. See setsurname, surname, get
set "jones "car "camry
setsurname
入力: "surname
出力: none
Used to select the 'surname', otherwise more commonly known as the 'container space', to use. All the containers (or variables) in turtleSpace have a surname, or family they belong to. Changing the surname allows you to use code containing single-dimension containers in different contexts (for example, different players) without having to modify it. You just set a different surname and run the code again. The default surname is "default
setsurname "player1
make "score 5
setsurname "player2
make "score 10
setsurname "player1
print :score
5
setvar
入力: turtle (word) | container (word) | value (word, number, list or boolean)
出力: none
Changes the contents of the container held by the specified turtle to the specified value. Technically bad form, but sometimes necessary.
setvar "myrtle "container 50
share
入力: "name
出力: none
Indicates that the container "name should be shared amongst all turtles. Sharing does not store the container: use persist to have it saved with the project or browser session. See persist
share "lives
shares
入力: none
出力: list
Returns a list of all the currently shared containers.
show shares
store
入力: database (name) | key (name) | container (name) OR [container1 container2…] (list)
出力: none
Inserts or updates a record in a database with the key name. Store stores container names and their contents, which can be restored later using the retrieve primitive. See newdatabase, retrieve
newdatabase "farm
make "pigs 5 make "cows 2 make "ducks 12
store "farm "livestock [pigs cows ducks]
surname
入力: none
出力: namespace (word)
Returns the surname of the current container (name) space. The default surname is 'default'. See setsurname.
print surname
default
swap

swap "container1 "container2
thing
入力: containername (word]
出力: output
Returns the contents of (the 'thing' in) the calling turtle's container of the provided container name. A longhand way of invoking the shortcut :container
show thing in "mycontainer
make "mycontainer thing in "mycontainer + 5
unburyname
入力: word or list
出力: none
Unburies the container(s) named in its input. See bury
unburyname "container
unshare
入力: name (word) or names (list)
