Cross platform. 2. Cross language. 3. Facilitate stateless operation of the Engine. 4. Keyboard format agnostic -- support both KMN and future LDML based keyboards. 5. Support querying Engine attributes. 6. Support querying Keyboard attributes. 7. Idempotent ## Design decisions in support of requirements: - Use C or C99 types and calling convention for the interface, it has the broadest language FFI support. [1,2] - Have client (Platform layer) code load keyboards, manage & pass state. [3,4,7] - Provide query calls to return static attributes data for keyboards and engine [5,6] - Provide get/set calls for client accessible keyboard state information [3,4] ## Glossary - __Platform layer:__ The code that consumes the Keyman Keyboard Processor API, and provides the operating system-specific handling of keystroke events and integration with applications. - __Client Application:__ The application that has the focus and receives text events from the Platform layer. - __Context:__ Text preceding the insertion point - __Marker:__ Positional state that can be placed in the Context. - __Keyboard:__ A set of rules for execution by an Engine - __Option:__ A variable in a dynamic or static key value store. - __Processor:__ The component that implements this API and can parse and execute a particular keyboard. - __State:__ An object that holds internal state of the Processor for a given insertion point - __Action:__ A directive output by the processor detailing how the Platform layer should transform the Client Application's text buffer. There may be several items produced by a single keyboard event. - __Keyboard Event:__ A virtual key event and modifier map received from the Platform layer to be processed with the state object for this Client application. - __Virtual Key:__ A code based on the US English layout, with values matching the Windows virtual key codes. See `keyboardprocessor_vkeys.h` for definitions. - __Modifier Key:__ The set of Control, Shift, Alt, Caps Lock keys. On some platforms these may have other names (e.g. Alt is called Option on macOS); other platform-specific modifiers such as Windows key are excluded from this set. Some modifiers are transient, such as Control, and others have long-lasting state, such as Caps Lock. ## API ### Namespace All calls, types and enums are prefixed with the namespace identifier `km_kbp_` ### API idioms Almost all calls marshalling variable length aggregate data in or out of an API object take the form: > km_kbp_status *fn_name*(object_ref, buffer_ptr, size_ptr) where the buffer is nullable and all other arguments are required (will result in an `KM_KBP_STATUS_INVALID_ARGUMENT` status being returned if nulled). When `buffer` is `nullptr` or `0` the function will place the size of the required buffer in the variable pointed to by `size_ptr`. Calls which result in the allocation of resources, regardless of resulting ownership, are of the form: > km_kbp_status *fn_name*(object_ref, out_ptr) where `out_ptr` is a valid pointer to a caller allocated variable to hold the resulting ouput. This is often a reference to a created object. All arguments are required (will result in an `KM_KBP_STATUS_INVALID_ARGUMENT` status being returned if nulled). For accessors to fixed size attributes of an object these will take the form: > attr_value __fn_name__(object_ref) `object_ref` is required to be valid and will result in a nonsense value being returned if `nullptr` or `0`. All dispose calls are designed to accept null as a valid value and will do nothing in that event. ```c */ #include #include #include #include #define KM_KBP_LIB_CURRENT @lib_curr@ #define KM_KBP_LIB_AGE @lib_age@ #define KM_KBP_LIB_REVISION @lib_rev@ #if defined(__cplusplus) extern "C" { #endif // Basic types // #if defined(__cplusplus) typedef char16_t km_kbp_cp; typedef char32_t km_kbp_usv; #else typedef uint16_t km_kbp_cp; // code point typedef uint32_t km_kbp_usv; // Unicode Scalar Value #endif typedef uint16_t km_kbp_virtual_key; // A virtual key code. typedef uint32_t km_kbp_status; // Status return code. // Opaque object types. // typedef struct km_kbp_context km_kbp_context; typedef struct km_kbp_keyboard km_kbp_keyboard; typedef struct km_kbp_state km_kbp_state; typedef struct km_kbp_options km_kbp_options; // Forward declarations // typedef struct km_kbp_option_item km_kbp_option_item; /*``` ### Error Handling Error handling and success failure notification are communicated through a general mechanism similar to COM’s `HRESULT` scheme (unlike COM, any non-zero value is an error).

For HRESULT codes this only permits failure codes to be passed. ### Context The context is the text prior to the insertion point (caret, cursor). The context is constructed by the Platform layer, typically by interrogating the Client Application. The context will be updated by the engine for keystroke events. If the Platform layer code caches the context, the context should be reset when a context state change is detected. Context state changes can occur when the user uses the mouse to move the insertion point, uses cursor keys, switches applications or input fields, or presses hotkeys such as Ctrl+N to start a new document. The full set of context state change triggers is up to the Platform layer. Context can also contain positional Markers (also known as 'deadkeys' in kmn keyboards), which are transitory state flags that are erased whenever a context state change is detected. Markers are always controlled by the Engine. Contexts are always owned by their state. They may be set to a list of context_items or interrogated for their current list of context items. ```c */ enum km_kbp_context_type { KM_KBP_CT_END, KM_KBP_CT_CHAR, KM_KBP_CT_MARKER }; typedef struct { uint8_t type; uint8_t _reserved[3]; union { km_kbp_usv character; uint32_t marker; }; } km_kbp_context_item; #define KM_KBP_CONTEXT_ITEM_END {KM_KBP_CT_END, {0,}, {0,}} /* ``` ### `km_kbp_context_items_from_utf16` ##### Description: Convert a UTF16 encoded Unicode string into an array of `km_kbp_context_item` structures.

You may need to set `SDKVER` environement variable to the current Windows SDK version, if it cannot be automatically detected, e.g.: ```DOS set SDKVER=10.0.19041.0 ``` To build: ```DOS build.bat all ``` ### Building on Linux, macOS For all other platforms, in your source directory do the following: ```bash cd desktop meson build --werror cd build ninja meson test ``` For a debug build, pass `--buildtype debug` to meson. ## Note on kmcomp kmcomp is the command-line compiler from Keyman Developer, available from or in this repo in `/windows/src/developer/kmcomp`. The compiler is currently available as a Windows PE executable only, but it does run under WINE. ## Additional configuration notes ### Windows The search path can be edited through System settings / Advanced system settings / Environment Variables / User environment variables. If you have Keyman Developer installed, add `%KeymanDeveloperPath%` to your path. Otherwise, add the path where you extracted the kmcomp archive. ### Linux You need a wrapper `kmcomp` shell script: ```bash #!/bin/bash wine `dirname "$0"`/kmcomp.exe "$@" ``` Place this in the same folder as you extracted kmcomp.exe, and `chmod +x kmcomp`. Add the folder to the path (e.g. `export PATH=/path/to/kmcomp:$PATH`, which you can add to `.bashrc`) ### macOS TODO keyman-keyboardprocessor-14.0.287/doc/hotdoc.json0000644000175000000620000000052314210311467020340 0ustar bobstaff{ "project_name": "@project_name@", "project_version": "@project_version@", "sitemap": "../../doc/sitemap.txt", "index": "../../doc/markdown_files/index.md", "c_sources": [ "../include/keyboardprocessor.h" ], "c_smart_index" : true, "output": ".", "extra_assets": [ "../../assets" ] } keyman-keyboardprocessor-14.0.287/doc/sitemap.txt0000644000175000000620000000002214210311467020362 0ustar bobstaffindex.md c-index keyman-keyboardprocessor-14.0.287/doc/meson.build0000644000175000000620000000200114210311467020320 0ustar bobstaff# Copyright: © 2018 SIL International. # Description: Cross platform build script to extract and generate # documentation for the API.

Cross platform. 2. Cross language. 3. Facilitate stateless operation of the Engine. 4. Keyboard format agnostic -- support both KMN and future LDML based keyboards. 5. Support querying Engine attributes. 6. Support querying Keyboard attributes. 7. Idempotent ## Design decisions in support of requirements: - Use C or C99 types and calling convention for the interface, it has the broadest language FFI support. [1,2] - Have client (platform glue) code load keyboards, manage & pass state. [3,4,7] - Provide query calls to return static attributes data for keyboards and engine [5,6] - Provide get/set calls for client accessible keyboard state information [3,4] ## Glossary - __Platform layer:__ the code that consumes the Keyman Keyboard Processor API, and provides the operating system-specific handling of keystroke events and integration with applications. - __Client Application:__ the application that has the focus and receives text events from the Platform layer. - __Context:__ Text preceding the insertion point - __Marker:__ Positional state that can be placed in the Context. - __Keyboard:__ A set of rules for execution by an Engine - __Option:__ A variable in a dynamic or static key value store. - __Processor:__ The component that implements this API and can parse and execute a particular keyboard. - __State:__ An object that holds internal state of the Processor for a given insertion point - __Action:__ A directive output by the processor detailing how the Platform layer should transform the Client Application's text buffer. There may be several items produced by a single keyboard event. - __Keyboard Event:__ A virtual key board event and modifier map recevied from the Platform layer to be processed with the state object for this Client application. - __Virtual Key:__ A code based on the US English layout, with values matching the Windows virtual key codes. See `keyboardprocessor_vkeys.h` for definitions. - __Modifier Key:__ The set of Control, Shift, Alt, Caps Lock keys. On some platforms these may have other names (e.g. Alt is called Option on macOS); other platform-specific modifiers such as Windows key are excluded from this set. Some modifiers are transient, such as Control, and others have long-lasting state, such as Caps Lock. ## API ### Namespace All calls, types and enums are prefixed with the namespace identifier `km_kbp_` keyman-keyboardprocessor-14.0.287/doc/introspection.schema0000644000175000000620000000345214210311467022253 0ustar bobstaff{"$schema": "http://json-schema.org/draft-06/schema#", "$id": "@replace_me_with_introspection_schema_uri@", "$comment": "© 2018 SIL International.
