This is used to parse the body of statements as it also parses template data if appropriate. The parser checks first if the current token is a colon and skips it if there is one. Then it checks for the block end and parses until if one of the `end_tokens` is reached. Per default the active token in the stream at the end of the call is the matched end token. If this is not wanted `drop_needle` can be set to `True` and the end token is removed. �colonrU �eof)r, �skip_if�expect�subparser> rW rR �next)r5 rO rq �resultr8 r8 r9 �parse_statements� s zParser.parse_statementsc C sf t | j�j}| jdd�}| j�d�r | �� }tj|||d�S | �d�}| j ddd�}tj ||||d�S )zParse an assign statement.T)�with_namespace�assignr[ N)z name:endset�rq ) rw r, r< �parse_assign_targetrt � parse_tupler �Assign� parse_filterry � AssignBlock)r5 r< �target�expr� filter_node�bodyr8 r8 r9 � parse_set� s zParser.parse_setc C s� | j �d�j}| jdd�}| j �d� | jddd�}d}| j �d �r&| �� }| j �d �}| �d �}t| j �j d kr<g }n| jd dd�}t j |||||||d�S )zParse a for loop.zname:for)�name:in)rS r� F)�name:recursive)� with_condexprrS N�name:ifr� )� name:endfor� name:else�endfor)r� Tr| r[ ) r, ru r< r} r~ rt �parse_expressionry rw re r �For)r5 r< r� �iter�test� recursiver� �else_r8 r8 r9 � parse_for� s � zParser.parse_forc C s� t j| j�d�jd� }} | jdd�|_| �d�|_g |_ g |_ t | j�}|�d�r;t j| jj jd�}|j � |� q |�d�rH| jd dd �|_ |S ) zParse an if construct.r� r[ TF�r� )� name:elifr� � name:endifr� r� )r� r| )r �Ifr, ru r< r~ r� ry r� �elif_r� rw r> rH )r5 �noderx rl r8 r8 r9 �parse_if� s zParser.parse_ifc C s� t jt| j�jd�}g }g }| jjjdkr?|r | j�d� | �� }|� d� |� |� | j�d� |� | � � � | jjjdks||_ ||_ | jddd�|_|S ) Nr[ rU �comma�paramr{ )z name:endwithTr| )r �Withrw r, r< r> rW ru r} �set_ctxrH r� �targets�valuesry r� )r5 r� r� r� r� r8 r8 r9 � parse_with s �zParser.parse_withc C sD t jt| j�jd�}t �d| �� �g|_| jddd�|_ t � |g�S )Nr[ r )zname:endautoescapeTr| ) r �ScopedEvalContextModifierrw r, r< �Keywordr� �optionsry r� �Scope�r5 r� r8 r8 r9 �parse_autoescape s zParser.parse_autoescapec C s� t jt| j�jd�}| j�d�j|_| j�d�|_ | j�d�|_ | jj j dkr,| � d� | jddd �|_|j rFtd d � |jD ��sF| � d � | j�d |j � |S )Nr[ r' z name:scopedz name:requiredr zpBlock names in Jinja have to be valid Python identifiers and may not contain hyphens, use an underscore instead.)z name:endblockTr| c s s2 � | ]}|j D ]}t|t j�o|j�� V qqd S �N)r � isinstance� TemplateData�data�isspace)�.0r� �childr8 r8 r9 � <genexpr>: s � �� �z%Parser.parse_block.<locals>.<genexpr>z7Required blocks can only contain comments or whitespacezname:)r �Blockrw r, r< ru re r' rt �scoped�requiredr> rW r?

As Jinja allows assignments to tuples, this function can parse all allowed assignment targets. Per default assignments to tuples are parsed, that can be disable however by setting `with_tuple` to `False`. If only assignments to names are wanted `name_only` can be set to `True`. The `extra_end_rules` parameter is forwarded to the tuple parsing function. If `with_namespace` is enabled, a namespace assignment may be parsed. �dotr' r[ �storeT)� simplifiedrS zcan't assign to )r, r� rW ru rw r �NSRefre r< �Namer~ � parse_primaryr� � can_assignr? �__name__�lower)r5 r� r� rS rz rl �attrr� r8 r8 r9 r} � s& � �r� c C s |r| � � S | �� S )z�Parse an expression.

This method could also return a regular expression instead of a tuple if no commas where found. The default parsing mode is a full tuple. If `simplified` is `True` only names and literals are parsed. The `no_condexpr` parameter is forwarded to :meth:`parse_expression`. Because tuples do not require delimiters and may end in a bogus comma an extra hint is needed that marks the end of a tuple. For example for loops support tuples between `for` and `in`. In that case the `extra_end_rules` is set to ``['name:in']``. `explicit_parentheses` is true if the parsing was triggered by an expression in parentheses. This is used to figure out if an empty tuple is a valid expression or not. r* c s � j dd�S )NFr� )r� r8 �r5 r8 r9 r1 � s z!Parser.parse_tuple.<locals>.parseFTr� r z Expected an expression, got r" r[ )r, r> r< r� r� r �Exprru rY rH rW r?
