13 # Usage:
14 #------------------------------------------------------------
15 # import yaml
16 # import yat
17 #
18 # dict = yaml.load(open(filename, "r").read())
19 # t = yat.Template(template, "\[", "\]")
20 # result = t.generate(dict)
21 #------------------------------------------------------------
22 #
23 # 1. Simple directive:
24 # [dictionary_key]
25 #
26 # Nested dictionaries can be expressed by dotted expression.
27 #
28 # example:
29 # dict = {"a": "This is a",
30 # "b": {"1": "This is b.1",
31 # "2": "This is b.2"}
32 # }
33 #
34 # template:
35 # [a]
36 #
37 # [b.1]
38 #
39 # [b.2]
40 #
41 # result:
42 # This is a
43 # This is b.1
44 # This is b.2
45 #
46 #
47 # 2. "for" directive:
48 # [for key in list] statement [endfor]
49 #
50 # Iterative evaluation for listed values is performed by "for" statement.
51 # In iteration at each evaluation, the value of the list is assigned to
52 # "key". The "key" also can be the nested dictionary directive.
53 #
54 # example:
55 # dict = {"list": [0, 1, 2],
56 # "listed_dict": [
57 # {"name": "x", "value": "1.0"},
58 # {"name": "y", "value": "0.2"},
59 # {"name": "z", "value": "0.1"}]}
60 #
61 # template:
62 # [for lst in list]
63 # [lst],
64 # [endfor]
65 # [for lst in listed_dict]
66 # [lst.name]: [lst.value]
67 #
68 # [endfor]
69 #
70 # result:
71 # 1, 2, 3,
72 # x: 1.0
73 # y: 0.2
74 # x: 0.1
75 #
76 #
77 # 3. "if-index" directive:
78 # [for key in val]
79 # [if-index key is first|even|odd|last|NUMBER] statement1
80 # [elif-index key is first|even|odd|last|NUMBER] statement2
81 # [endif][endfor]
82 #
83 # "if-index" is used to specify the index of the "for" iteration.
84 # The "key" string which is defined in the "for" statement is used as index.
85 # A number or predefined directives such as "first", "even", "odd" and
86 # "last" can be used to specify the index.
87 #
88 # example:
89 # dict = {"list": [0,1,2,3,4,5,6,7,8,9,10]}
90 #
91 # template:
92 # [for key in list]
93 # [if-index key is 3] [key] is hoge!!
94 # [elif-index key is 6] [key] is foo!!
95 # [elif-index key is 9] [key] is bar!!
96 # [elif-index key is first] [key] is first
97 # [elif-index key is last] Omoro-------!!!!
98 # [elif-index key is odd] [key] is odd number
99 # [elif-index key is even] [key] is even number
100 # [endif]
101 # [endfor]
102 #
103 # result:
104 # 0 is first
105 # 1 is odd number
106 # 2 is even number
107 # 3 is hoge!!
108 # 4 is even number
109 # 5 is odd number
110 # 6 is foo!!
111 # 7 is odd number
112 # 8 is even number
113 # 9 is bar!!
114 # Omoro-------!!!!
115 #
116 #
117 # 4. "if" directive: [if key is value] text1 [else] text2 [endif]
118 # If "key" is "value", "text1" appears, otherwise "text2" appears.
119 #
120 # example:
121 # dict = {"key1": "a", "key2": "b"}
122 #
123 # template:
124 # [if key1 is a]
125 # The key1 is "a".
126 # [else]
127 # This key1 is not "a".
128 # [endif]
129 #
130 # result:
131 # The key1 is "a".
132 #
133 #
134 # 5. "if-any" directive: [if-any key1] text1 [else] text2 [endif]
135 # If the "key1" exists in the dictionary, "text1" appears, otherwise
136 # "text2" appears.
137 #
138 # example:
139 # dict = {"key1": "a", "key2": "b"}
140 #
141 # template:
142 # [if-any key1]
143 # key1 exists.
144 # [endif][if-any key3]
145 # key3 exists.
146 # [else]
147 # key3 does not exists.
148 # [endif]
149 #
150 # result:
151 # key1 exists.
152 # key3 does not exists.
153 #
154 #
155 # 6. bracket and comment:
156 # [[] is left bracket if begin mark is "["
157 # [# comment ] is comment if begin/end marks are "[" and "]"
158 #
159 # example:
160 # dict = {}
161 #
162 # template:
163 # [[]bracket]
164 # [# comment]
165 #
166 # result:
