Function Documentation

◆ callback_reader_free()

void callback_reader_free ( CallbackReader reader)

◆ callback_reader_start()

void callback_reader_start ( CallbackReader reader,
const char *  type 
)

◆ channel_all_info()

Array channel_all_info ( void  )

◆ channel_alloc()

Channel* channel_alloc ( ChannelStreamType  type)

Allocates a channel.

Channel is allocated with refcount 1, which should be decreased when the underlying stream closes.

◆ channel_close()

bool channel_close ( uint64_t  id,
ChannelPart  part,
const char **  error 
)

Closes a channel

Parameters
idThe channel id
Returns
true if successful, false otherwise

◆ channel_connect()

uint64_t channel_connect ( bool  tcp,
const char *  address,
bool  rpc,
CallbackReader  on_output,
int  timeout,
const char **  error 
)

◆ channel_create_event()

void channel_create_event ( Channel chan,
const char *  ext_source 
)

◆ channel_decref()

void channel_decref ( Channel chan)

◆ channel_from_connection()

void channel_from_connection ( SocketWatcher watcher)

Creates an RPC channel from a tcp/pipe socket connection

Parameters
watcherThe SocketWatcher ready to accept the connection

◆ channel_from_stdio()

uint64_t channel_from_stdio ( bool  rpc,
CallbackReader  on_output,
const char **  error 
)

Creates an API channel from stdin/stdout. This is used when embedding Neovim

◆ channel_incref()

void channel_incref ( Channel chan)

◆ channel_info()

Dictionary channel_info ( uint64_t  id)

◆ channel_info_changed()

void channel_info_changed ( Channel chan,
bool  new 
)

◆ channel_init()

void channel_init ( void  )

Initializes the module.

◆ channel_job_running()

bool channel_job_running ( uint64_t  id)

◆ channel_job_start()

Channel* channel_job_start ( char **  argv,
CallbackReader  on_stdout,
CallbackReader  on_stderr,
Callback  on_exit,
bool  pty,
bool  rpc,
bool  overlapped,
bool  detach,
ChannelStdinMode  stdin_mode,
const char *  cwd,
uint16_t  pty_width,
uint16_t  pty_height,
dict_T env,
varnumber_T status_out 
)

Starts a job and returns the associated channel

Parameters
[in]argvArguments vector specifying the command to run, NULL-terminated
[in]on_stdoutCallback to read the job's stdout
[in]on_stderrCallback to read the job's stderr
[in]on_exitCallback to receive the job's exit status
[in]ptyTrue if the job should run attached to a pty
[in]rpcTrue to communicate with the job using msgpack-rpc, on_stdout is ignored
[in]detachTrue if the job should not be killed when nvim exits, ignored if pty is true
[in]stdin_modeStdin mode. Either kChannelStdinPipe to open a channel for stdin or kChannelStdinNull to leave stdin disconnected.
[in]cwdInitial working directory for the job. Nvim's working directory if cwd is NULL
[in]pty_widthWidth of the pty, ignored if pty is false
[in]pty_heightHeight of the pty, ignored if pty is false
[in]envNvim's configured environment is used if this is NULL, otherwise defines all environment variables
[out]status_out0 for invalid arguments, > 0 for the channel id, < 0 if the job can't start
Returns
[allocated] channel

◆ channel_reader_callbacks()

void channel_reader_callbacks ( Channel chan,
CallbackReader reader 
)

◆ channel_send()

size_t channel_send ( uint64_t  id,
char *  data,
size_t  len,
bool  data_owned,
const char **  error 
)
Parameters
datawill be consumed

◆ channel_teardown()

void channel_teardown ( void  )

Teardown the module.

◆ channel_terminal_open()

void channel_terminal_open ( buf_T buf,
Channel chan 
)

Open terminal for channel

Channel chan is assumed to be an open pty channel, and buf is assumed to be a new, unmodified buffer.

◆ on_channel_data()

void on_channel_data ( Stream stream,
RBuffer buf,
size_t  count,
void data,
bool  eof 
)

◆ on_job_stderr()

void on_job_stderr ( Stream stream,
RBuffer buf,
size_t  count,
void data,
bool  eof 
)
