35
+ =====
36
+
37
+ Jinja is a fast, expressive, extensible templating engine. Special
38
+ placeholders in the template allow writing code similar to Python
39
+ syntax. Then the template is passed data to render the final document.
40
+
41
+ It includes:
42
+
43
+ - Template inheritance and inclusion.
44
+ - Define and import macros within templates.
45
+ - HTML templates can use autoescaping to prevent XSS from untrusted
46
+ user input.
47
+ - A sandboxed environment can safely render untrusted templates.
48
+ - AsyncIO support for generating templates and calling async
49
+ functions.
50
+ - I18N support with Babel.
51
+ - Templates are compiled to optimized Python code just-in-time and
52
+ cached, or can be compiled ahead-of-time.
53
+ - Exceptions point to the correct line in templates to make debugging
54
+ easier.
55
+ - Extensible filters, tests, functions, and even syntax.
56
+
57
+ Jinja's philosophy is that while application logic belongs in Python if
58
+ possible, it shouldn't make the template designer's job difficult by
59
+ restricting functionality too much.

+ MarkupSafe
28
+ ==========
29
+
30
+ MarkupSafe implements a text object that escapes characters so it is
31
+ safe to use in HTML and XML. Characters that have special meanings are
32
+ replaced so that they display as the actual characters. This mitigates
33
+ injection attacks, meaning untrusted user input can safely be displayed
34
+ on a page.

+ Installing
38
+ ----------
39
+
40
+ Install and update using `pip`_:
41
+
42
+ .. code-block:: text
43
+
44
+ pip install -U MarkupSafe
45
+
46
+ .. _pip: https://pip.pypa.io/en/stable/getting-started/
47
+
48
+
49
+ Examples
50
+ --------
51
+
52
+ .. code-block:: pycon
53
+
54
+ >>> from markupsafe import Markup, escape
55
+
56
+ >>> # escape replaces special characters and wraps in Markup
57
+ >>> escape("<script>alert(document.cookie);</script>")
58
+ Markup('&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
59
+
60
+ >>> # wrap in Markup to mark text "safe" and prevent escaping
61
+ >>> Markup("<strong>Hello</strong>")
62
+ Markup('<strong>hello</strong>')
63
+
64
+ >>> escape(Markup("<strong>Hello</strong>"))
65
+ Markup('<strong>hello</strong>')
66
+
67
+ >>> # Markup is a str subclass
68
+ >>> # methods and operators escape their arguments
69
+ >>> template = Markup("Hello <em>{name}</em>")
70
+ >>> template.format(name='"World"')
71
+ Markup('Hello <em>&#34;World&#34;</em>')

+ BLP1 files, used mostly in Warcraft III, are not fully supported.
10
+ All types of BLP2 files used in World of Warcraft are supported.
11
+
12
+ The BLP file structure consists of a header, up to 16 mipmaps of the
13
+ texture
14
+
15
+ Texture sizes must be powers of two, though the two dimensions do
16
+ not have to be equal; 512x256 is valid, but 512x200 is not.
17
+ The first mipmap (mipmap #0) is the full size image; each subsequent
18
+ mipmap halves both dimensions. The final mipmap should be 1x1.
19
+
20
+ BLP files come in many different flavours:
21
+ * JPEG-compressed (type == 0) - only supported for BLP1.
22
+ * RAW images (type == 1, encoding == 1). Each mipmap is stored as an
23
+ array of 8-bit values, one per pixel, left to right, top to bottom.
24
+ Each value is an index to the palette.
25
+ * DXT-compressed (type == 1, encoding == 2):
26
+ - DXT1 compression is used if alpha_encoding == 0.
27
+ - An additional alpha bit is used if alpha_depth == 1.
28
+ - DXT3 compression is used if alpha_encoding == 1.
29
+ - DXT5 compression is used if alpha_encoding == 7.

+ Independence War 2: Edge Of Chaos - Texture File Format - 16 October 2001
10
+
11
+ The textures used for 3D objects in Independence War 2: Edge Of Chaos are in a
12
+ packed custom format called FTEX. This file format uses file extensions FTC
13
+ and FTU.
14
+ * FTC files are compressed textures (using standard texture compression).
15
+ * FTU files are not compressed.
16
+ Texture File Format
17
+ The FTC and FTU texture files both use the same format. This
18
+ has the following structure:
19
+ {header}
20
+ {format_directory}
21
+ {data}
22
+ Where:
23
+ {header} = {
24
+ u32:magic,
25
+ u32:version,
26
+ u32:width,
27
+ u32:height,
28
+ u32:mipmap_count,
29
+ u32:format_count
30
+ }
31
+
32
+ * The "magic" number is "FTEX".
33
+ * "width" and "height" are the dimensions of the texture.
34
+ * "mipmap_count" is the number of mipmaps in the texture.
35
+ * "format_count" is the number of texture formats (different versions of the
36
+ same texture) in this file.
37
+
38
+ {format_directory} = format_count * { u32:format, u32:where }
39
+
40
+ The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB
41
+ uncompressed textures.
42
+ The texture data for a format starts at the position "where" in the file.
43
+
44
+ Each set of texture data in the file has the following structure:
45
+ {data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } }
46
+ * "mipmap_size" is the number of bytes in that mip level. For compressed
47
+ textures this is the size of the texture data compressed with DXT1. For 24 bit
48
+ uncompressed textures, this is 3 * width * height. Following this are the image
49
+ bytes for that mipmap level.
50
+
51
+ Note: All data is stored in little-Endian (Intel) byte order.
