<em>API LEVELS</em>
- The API of the m17n library is divided into these four.
+ The API of the m17n library is divided into these five.
<ol>
<li> CORE API
- It provides basic modules to handle M-texts. They do not require
- the m17n database. To use this API, an application program must
- include <m17n-core<EM></EM>.h> and be linked by -lm17n-core.

+ program must include <m17n<EM></EM>.h> and be linked with
-lm17n-core -lm17n.
When you use this API, CORE API is also available.
+ <li> FLT API
+
+ It provides modules for text shaping using @ref mdbFLT. To use
+ this API, an application program must include <m17n<EM></EM>.h>
+ and be linked with -lm17n-core -lm17n-flt.
+
+ When you use this API, CORE API is also available.
+
<li> GUI API
It provides GUI modules such as drawing and inputting M-texts on a
- graphic device. The API itself is independent on a graphic device
- but most functions require an argument MFrame which is created for
- a specific type of graphic device. Currently, a null device, X
- Window System, and an image date (gdImagePtr) of GD library are
- supported as a graphic device.
+ 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 the null device, you can't draw text nor use an
- input method (but, for instance, the function mdraw_glyph_list ()
- is available).
+ 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 GD library, you can use all drawing API but can't
- use input method.
+ On a frame of the GD library, you can use all drawing API but
+ cannot use input methods.
- To use this device, an application program must include
- <m17n-gui<EM></EM>.h> and be linked by -lm17n-core -lm17n
+ To use this API, an application program must include
+ <m17n-gui<EM></EM>.h> and be linked with -lm17n-core -lm17n
-lm17n-gui.
- When you use this API, CORE and SHELL API are also available.
+ When you use this API, CORE, SHELL, and FLT APIs are also
+ available.
<li> MISC API
It provides miscellaneous functions to support error handling and
- debugging. This API cannot be used by itself, but with one or
- more APIs listed above. To use the API, an application program
- must include <m17n-misc<EM></EM>.h> in addition to one of a header
- file described above.
+ 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 <m17n-misc<EM></EM>.h> in
+ addition to one of the header files described above.
</ol>
See also the section @ref m17n-config "m17n-config(1)".
- <em>ENVIRONMENT VARIABLE</em>
+ <em>ENVIRONMENT VARIABLES</em>
- The m17n library pays attention to these environment variables.
+ The m17n library pays attention to the following environment
+ variables.
<ul>
<li> @c M17NDIR
- Name of a directory that contains data of the m17n database. See
- @ref m17nDatabase for more details.
+ The name of the directory that contains data of the m17n database.
+ See @ref m17nDatabase for details.
- <li> @c MDEBUG_XXXX
+ <li> @c MDEBUG_XXX
- Environment variables whose name start by "MDEBUG_" controls
- printing of debug information. See @ref m17nDebug for more
- details.
+ Environment variables whose names start with "MDEBUG_" control
+ debug information output. See @ref m17nDebug for details.
</ul>
<em>API NAMING CONVENTION</em>
- 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).
-
+ The m17n library exports functions, variables, macros, and types.
+ All of them start with the letter 'm' or 'M', and are followed by
+ an object name (e.g. "symbol", "plist") or a module name
+ (e.g. draw, input). Note that the name of M-text objects start
+ with "mtext" and not with "mmtext".
+
<ul>
<li> functions -- mobject () or mobject_xxx ()
- They start with 'm' followed by lower case object name. For
- example, msymbol (), mtext_ref_char (), mdraw_text ().
+ They start with 'm' and are followed by an object name in lower
+ case. Words are separated by '_'. For example, msymbol (),
+ mtext_ref_char (), mdraw_text ().
<li> non-symbol variables -- mobject, or mobject_xxx
<li> symbol variables -- Mname
- Variables of type MSymbol start with 'M' followed by their names
- (e.g. Mlanguage (name is "language"), Miso_2022 (name is
- "iso-2022").
+ Variables of the type MSymbol start with 'M' and are followed by
+ their names. Words are separated by '_'. For example, Mlanguage
+ (the name is "language"), Miso_2022 (the name is "iso-2022").
<li> macros -- MOBJECT_XXX
- They start by 'M' followed by upper case object names.
+ They start with 'M' and are followed by an object name in upper
+ case. Words are separated by '_'.
<li> types -- MObject or MObjectXxx
- They start by 'M' followed by capitalized object names (e.g.
- MConverter, MInputDriver).
+ They start with 'M' and are followed by capitalized object names.
+ Words are concatenated directly and no '_' are used. For example,
+ MConverter, MInputDriver.

@brief Error handling of the m17n library.
There are two types of errors that may happen in a function of
<li> MDEBUG_FONT -- If set to 1, print information about fonts
being selected and opened.
- <li> MDEBUG_FONT_FLT -- If set to 1, print information about which
- command of Font Layout Table are being executed.
-
- <li> MDEBUG_FONT_OTF -- If set to 1, print information about which
- feature of OpenType Layout Table are being executed.
+ <li> MDEBUG_FLT -- If set to 1, 2, or 3, print information about
+ which command of Font Layout Table are being executed. The bigger
+ number prints the more detailed information.
<li> MDEBUG_INPUT -- If set to 1, print information about how an
input method is running.
<li> MDEBUG_DATABASE -- 1 ¤Ê¤é¤Ð¡¢m17n
