25 @brief The m17n database and API for it.
27 The m17n library acquires various kinds of information
28 from data in the <i> m17n database</i> on demand. Application
29 programs can also add/load their original data to/from the m17n
30 database by setting the variable #mdatabase_dir to an
31 application-specific directory and storing data in it. Users can
32 overwrite those data by storing preferable data in the directory
33 specified by the environment variable "M17NDIR", or if it is not
34 set, in the directory "~/.m17n.d".
36 The m17n database contains multiple heterogeneous data, and each
37 data is identified by four tags; TAG0, TAG1, TAG2, TAG3. Each tag
40 TAG0 specifies the type of data stored in the database as below.
43 If TAG0 is #Mchar_table, the data is of the @e chartable @e
44 type and provides information about each character. In this case,
45 TAG1 specifies the type of the information and must be #Msymbol,
46 #Minteger, #Mstring, #Mtext, or #Mplist. TAG2 and TAG3 can be any
50 If TAG0 is #Mcharset, the data is of the @e charset @e type
51 and provides a decode/encode mapping table for a charset. In this
52 case, TAG1 must be a symbol representing a charset. TAG2 and TAG3
56 If TAG0 is neither #Mchar_table nor #Mcharset, the data is of
57 the @e plist @e type. See the documentation of the
58 mdatabase_load () function for the details.
59 In this case, TAG1, TAG2, and TAG3 can be any symbols.
61 The notation \<TAG0, TAG1, TAG2, TAG3\> means a data with those
64 Application programs first calls the mdatabase_find () function to
65 get a pointer to an object of the type #MDatabase. That object
66 holds information about the specified data. When it is
67 successfully returned, the mdatabase_load () function loads the
68 data. The implementation of the structure #MDatabase is
69 concealed from application programs.
