785d73306d fix #44 add busy mode 2020-03-28 12:12:56 +01:00
prozessorkern
96cf0c8d65 added busy command to the example + declared option parser options as const 2020-03-28 12:08:01 +01:00
prozessorkern
d7962a54dc added busy mode and test 
a command can now return SHELLMATTA_BUSY
This will be passed back to the caller of processData
afterwards the instance has to be called with the same parameters
The shellmatta will then just call the busy command until it finishes
as soon as the command returns != SHELLMATTA_BUSY the instance will continue processing the rest of the input data
 2020-03-28 11:26:50 +01:00

3b99ad2a56 fix #43 added a config interface to change the newline character expected 2020-03-27 18:35:07 +01:00

c2e4324236 bugfix - now stdin returns 0 if the heredoc body is empty 2020-03-26 05:55:38 +01:00
prozessorkern
5e84f1b022 added continuous mode support fix #3 
If a command returns SHELLMATTA_CONTINUE all received data is passed to this command until it returns != SHELLMATTA_CONTINUE or a cancel is received
The data is passed stdin like and can be read byte by byte vie shellmatta_read
The stdin buffer is overwritten witch each new char
