29 | 25 | |
|
30 | 26 | template expansion works like this. a map file contains key=value |
|
31 | 27 | pairs. if value is quoted, it is treated as string. otherwise, it |
|
32 | 28 | is treated as name of template file. |
|
33 | 29 | |
|
34 | 30 | templater is asked to expand a key in map. it looks up key, and |
|
35 | 31 | looks for atrings like this: {foo}. it expands {foo} by looking up |
|
36 | 32 | foo in map, and substituting it. expansion is recursive: it stops |
|
37 | 33 | when there is no more {foo} to replace. |
|
38 | 34 | |
|
39 | 35 | expansion also allows formatting and filtering. |
|
40 | 36 | |
|
41 | 37 | format uses key to expand each item in list. syntax is |
|
42 | 38 | {key%format}. |
|
43 | 39 | |
|
44 | 40 | filter uses function to transform value. syntax is |
