cb982ea8df apps/nshlib: Eliminate more new warnings found in build testing. 2018-10-02 11:16:15 -06:00

2bc4d1e8e2 apps/nshlib/nsh_parse.c: Fix a warning (really a bug) detected in build testing. 2018-10-02 11:08:17 -06:00

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

dbf152cbeb apps/nshlib: (1) NSH prompt string is now configurable. nsh> is still the default. (2) Increase the default configuration for the maximum number of command line arguments to 7 (CONFIG_NSH_MAXARGUMENTS). This is needed for 'mount' with the -o option. 2018-08-23 07:34:30 -06:00

f2ef84f048 apps/nshlib: Back out 516a743344. While the change is fuly functional and adds a pleasing symmetry to the control commands, it is also redundant and serves no real purpose other than requiring more FLASH. 2018-08-12 06:15:29 -06:00

ff192a4a58 apps/nshlib: I was able to cause an assertion with some typos in an testing the 'fi' command. Not an important thing, but this will protect against the assertion. 2018-08-11 09:30:53 -06:00

cb556d6236 apps/nshlib: Add parsing support for back-slash quoted characters. Currenlty only implemented properly if CONFIG_NSH_ARGCAT is also selected. This commit is in response to Bitbucket Issue 11 opened by Maciej Wójcik 2018-08-06 13:28:31 -06:00

nsh_parse.c: fix 'while' and 'until' loop condition

The loop condition logic was inverted:
  while true; do echo "test"; done
would exit immediately, while using 'until' would stay in the loop.
This is the opposite of how it is supposed to work.
The reason is that 'state' was set wrong because 'whilematch' is a bool.

3fe720d1e2 Fixes for problems found by Coverity in the apps/ repository: 
nshlib/nsh_parse.c: Avoid truncating the strcmp result into a unsigned char variable.

    nshlib/nsh_netcmds.c: Check for valid hostip before using it.

    nshlib/nsh_ddcmd.c: Fix resouce leak when 'if=' or 'of=' params are repeated in the command line.  For example:

       dd if=/dev/null if=/dev/zero of=/dev/null or
       dd if=/dev/zero of=/dev/zero of=/dev/null
