+ @brief Introduction to the m17n library.
API LEVELS
- The API of the m17n library is divided into these four.
+ The API of the m17n library is divided into these five.
- CORE API
- It provides basic modules to handle M-texts. They don't require
- the m17n database. To use this API, an application program must
- include and be linked by -lm17n-core.
+ It provides basic modules to handle M-texts. To use this API, an
+ application program must include .h> and be
+ linked with -lm17n-core.
- SHELL API
- It provides modules that utilize the m17n database. They load
- various kinds of data from the database on demand. To use this
- API, an application program must include and be linked by
- -lm17n-core -lm17n. With that, CORE API is also available.
+ It provides modules for character properties, character set
+ handling, code conversion, etc. They load various kinds of
+ data from the database on demand. To use this API, an application
+ program must include .h> and be linked with
+ -lm17n-core -lm17n.
+
+ When you use this API, CORE API is also available.
+
+
- FLT API
+
+ It provides modules for text shaping using @ref mdbFLT. To use
+ this API, an application program must include .h>
+ and be linked with -lm17n-core -lm17n-flt.
+
+ When you use this API, CORE API is also available.
- GUI API
It provides GUI modules such as drawing and inputting M-texts on a
- window system. The API itself is independent on a window system,
- but the m17n library must be configured to use a specific window
- system. Currently, we support only the X Window System. To use
- this API, an application program must include and
- , and be linked by -lm17n-core -lm17n -lm17n-X. With
- that, CORE and SHELL APIs are also available.
+ graphic device. This API itself is independent of graphic
+ devices, but most functions require an argument MFrame that is
+ created for a specific type of graphic devices. The currently
+ supported graphic devices are null device, the X Window System,
+ and image data (gdImagePtr) of the GD library.
+
+ On a frame of a null device, you cannot draw text nor use input
+ methods. However, functions like mdraw_glyph_list (), etc. are
+ available.
+
+ On a frame of the X Window System, you can use the whole GUI API.
+
+ On a frame of the GD library, you can use all drawing API but
+ cannot use input methods.
+
+ To use this API, an application program must include
+ .h> and be linked with -lm17n-core -lm17n
+ -lm17n-gui.
+
+ When you use this API, CORE, SHELL, and FLT APIs are also
+ available.
- MISC API
It provides miscellaneous functions to support error handling and
- debugging. This API can't be used by itself, but with one or more
- APIs listed above. To use the API, an application program must
- include in addition to one of ,
- , and .
+ debugging. This API cannot be used standalone; it must be used
+ with one or more APIs listed above. To use this API, an
+ application program must include .h> in
+ addition to one of the header files described above.
See also the section @ref m17n-config "m17n-config(1)".
- ENVIRONMENT VARIABLE
+ ENVIRONMENT VARIABLES
- The m17n library pays attention to these environment variables.
+ The m17n library pays attention to the following environment
+ variables.
- @c M17NDIR
- Name of a directory that contains data of the m17n database. See
- @ref m17nDatabase for the detail.
+ The name of the directory that contains data of the m17n database.
+ See @ref m17nDatabase for details.
-
- @c MDEBUG_XXXX
+
- @c MDEBUG_XXX
- Environment variables whose name start by "MDEBUG_" controls
- printing of debug information. See @ref m17nDebug for the detail.
+ Environment variables whose names start with "MDEBUG_" control
+ debug information output. See @ref m17nDebug for details.
API NAMING CONVENTION
- The library exports functions, variables, macros, and types. All
- of them start by the letter 'm' or 'M' followed by an object name
- (e.g. "symbol" and "plist", but "mtext" object is given the name
- "text" to avoid double 'm' at the head) or a module name
- (e.g. draw, input).
