Parsing method: LALR

state 0

    (0) S' -> . command
    (1) command -> . operate NUMBER article
    (7) operate -> . OPERATE

    OPERATE         shift and go to state 3

    command                        shift and go to state 1
    operate                        shift and go to state 2

state 1

    (0) S' -> command .



state 2

    (1) command -> operate . NUMBER article

    NUMBER          shift and go to state 4


state 3

    (7) operate -> OPERATE .

    NUMBER          reduce using rule 7 (operate -> OPERATE .)


state 4

    (2) article -> . attribute article
    (6) article -> . KIND
    (3) attribute -> . COLOR
    (4) attribute -> . MATERIAL
    (5) attribute -> . SIZE

    KIND            shift and go to state 7

    MATERIAL        shift and go to state 9
    SIZE            shift and go to state 10

    article                        shift and go to state 5
    attribute                      shift and go to state 6

state 5

    (1) command -> operate NUMBER article .

    $end            reduce using rule 1 (command -> operate NUMBER article .)


state 6

    (2) article -> attribute . article
    (2) article -> . attribute article
    (6) article -> . KIND
    (3) attribute -> . COLOR
    (4) attribute -> . MATERIAL
    (5) attribute -> . SIZE

    KIND            shift and go to state 7
    COLOR           shift and go to state 8
    MATERIAL        shift and go to state 9

state 8

    (3) attribute -> COLOR .

    KIND            reduce using rule 3 (attribute -> COLOR .)
    COLOR           reduce using rule 3 (attribute -> COLOR .)
    MATERIAL        reduce using rule 3 (attribute -> COLOR .)
