19dc7cd3b3 nshlib/nsh_console.c: Add fflush to nsh_consolewrite(). This resolves this problem: 
> cat /dev/ttyCP &
  > echo ls >/dev/ttyCP

Can't get the 'ls' result immediately, because 'cat' cmd uses nsh_consolewrite() and that uses fwrite with no fflush. We can get the 'ls' result after type '\n', because nsh will fflush output when get '\n'.

e9edfd064f apps/nshlib: Add support for NSH local variables if CONFIG_NSH_VARS are set. These are like environment variables but are local to NSH. The importance of this is that these variables are *not* inherited when NSH creates a new task. The new command 'export' was added. In this case, the NSH variable will be promoted to an environment variable and will then be inherited by any tasks executed by NSH. 2018-10-01 13:30:25 -06:00

d03aa9112e Added support for set [{+|-}{e|x|xe|ex}] [<name> <value>] 
Set the 'exit on error control' and/or 'print a trace' of commands when parsing scripts in NSH.  The settinngs are in effect from the point of exection, until they are changed again, or in the case of the init script, the settings are returned to the default settings when it exits.

Included child scripts will run with the parents settings and changes made in the child script will effect the parent on return.

Use 'set -e' to enable and 'set +e' to disable (ignore) the exit condition on commands. The default is -e. Errors cause script to exit.

Use 'set -x' to enable and 'set +x' to disable (silence) printing a trace of the script commands as they are ececuted. The default is +x. No printing of a trace of script commands as they are executed.

7a98f10283 The alternate console device CONFIG_NSH_CONDEV must not be defined unconditionally. This causes errors when using Telnet sessions. This was solved by adding CONFIG_NSH_ALTCONDEV: CONFIG_NSH_ALTCONDEV enables or disables the feature then, if enabled, CONFIG_NSH_CONDEV provides the alternative console device name 2014-05-05 08:52:02 -06:00
