select BOARDCTL_ROMDISK if NSH_ROMFSETC
---help---
Build the NSH support library. This is used, for example, by
system/nsh in order to implement the full NuttShell (NSH).
if NSH_LIBRARY
menuconfig NSH_MOTD
bool "Message of the Day (MOTD)"
default n
---help---
Support a user-provided Message of the Day (MOTD) that will be
presented each time new NSH session is opened.
if NSH_MOTD
config NSH_PLATFORM_MOTD
bool "Platform MOTD"
default n
---help---
If this option is selected, the NSH will call into platform-specific
logic in order to get the MOTD. The function prototype for this
call is:
void platform_motd(FAR char *buffer, size_t buflen);
Where buffer is the location to return the MOTD and buflen is the
length of that buffer. The maximum size of the buffer is determined
by NSH_FILEIOSIZE. An appropriate location for the
implementation of platform_motd would be within apps/platform/<board>.
One newline will be inserted after the platform-supplied message.
platform_motd() is prototyped and described in apps/include/nshlib/nshlib.h
which may be included like:
#include "nshlib/nshlib.h"
config NSH_MOTD_STRING
string "MOTD String"
default "No MOTD string provided"
depends on !NSH_PLATFORM_MOTD
---help---
If NSH_MOTD is selected, but NSH_PLATFORM_MOTD is not, then a fixed
MOTD string will be used. That string is provided by this selection.
One newline will be inserted after supplied MOTD message.
endif # NSH_MOTD
menu "Command Line Configuration"
config NSH_PROMPT_STRING
string "Prompt String"
default "nsh> "
---help---
Provide the shell prompt string, default is "nsh> ".
choice

default NSH_READLINE if DEFAULT_SMALL
default NSH_CLE if !DEFAULT_SMALL
config NSH_READLINE
bool "Minimal readline()"
select SYSTEM_READLINE
---help---
Selects the minimal implementation of readline(). This minimal
implementation provides on backspace for command line editing.
config NSH_CLE
bool "Command Line Editor"
select SYSTEM_CLE
---help---
Selects the more extensive, EMACS-like command line editor.
Select this option only if (1) you don't mind a modest increase
in the FLASH footprint, and (2) you work with a terminal that
supports extensive VT100 editing commands.
Selecting this option will add probably 1.5-2KB to the FLASH
footprint.
endchoice
config NSH_LINELEN
int "Max command line length"
default 64 if DEFAULT_SMALL
default 80 if !DEFAULT_SMALL
---help---
The maximum length of one command line and of one output line.
Default: 64/80
config NSH_DISABLE_SEMICOLON
bool "Disable multiple commands per line"
default y if DEFAULT_SMALL
default n if !DEFAULT_SMALL
---help---
By default, you can enter multiple NSH commands on a line with each
command separated by a semicolon. You can disable this feature to
save a little memory on FLASH challenged platforms.
config NSH_QUOTE
bool "Enable back-slash quoting of characters"
default n if DEFAULT_SMALL || !NSH_ARGCAT
default y if !DEFAULT_SMALL && NSH_ARGCAT
---help---
Force special characters like back-quotes, quotation marks, and the
back-slash character itself to be treat like normal text.
This feature is only implemented properly for the case where
CONFIG_NSH_ARGCAT is also selected.
config NSH_CMDPARMS
bool "Enable commands as parameters"
default n if DEFAULT_SMALL
default y if !DEFAULT_SMALL
depends on !DISABLE_MOUNTPOINT
---help---
If selected, then the output from commands, from file applications, and
from NSH built-in commands can be used as arguments to other
commands. The entity to be executed is identified by enclosing the
command line in back quotes. For example,
set FOO `myprogram $BAR`
Will execute the program named myprogram passing it the value of the
environment variable BAR. The value of the environment variable FOO
is then set output of myprogram on stdout.
Because this feature commits significant resources, it is disabled by
default.
config NSH_MAXARGUMENTS
int "Maximum number of command arguments"
default 7
---help---
The maximum number of NSH command arguments.
Default: 7
config NSH_ARGCAT
bool "Concatenation of argument strings"
default n if DEFAULT_SMALL
default y if !DEFAULT_SMALL
---help---
Support concatenation of strings with environment variables or command
output. For example:
set FOO XYZ
set BAR 123
set FOOBAR ABC_${FOO}_${BAR}
would set the environment variable FOO to XYZ, BAR to 123 and FOOBAR
to ABC_XYZ_123. If NSH_ARGCAT is not selected, then a slightly small
FLASH footprint results but then also only simple environment
variables like $FOO can be used on the command line.
config NSH_NESTDEPTH
int "Maximum command nesting"
default 3
---help---
The maximum number of nested if-then[-else]-fi sequences that
are permissible. Default: 3
config NSH_DISABLEBG
bool "Disable background commands"
default y if DEFAULT_SMALL
default n if !DEFAULT_SMALL
---help---
This can be set to 'y' to suppress support for background
commands. This setting disables the 'nice' command prefix and
the '&' command suffix. This would only be set on systems
where a minimal footprint is a necessity and background command
execution is not.
endmenu # Command Line Configuration
config NSH_BUILTIN_APPS
bool "Enable built-in applications"
default n
depends on BUILTIN
---help---
Support external registered, "built-in" applications that can be
executed from the NSH command line (see apps/README.txt for
more information). This options requires support for builtin
applications (BUILTIN).
config NSH_FILE_APPS
bool "Enable execution of program files"
default n
depends on LIBC_EXECFUNCS
---help---
Support execution of program files residing within a file
system. This options requires support for the posix_spawn()
interface (LIBC_EXECFUNCS).

By default, there are no internal NSH variables. NSH will use OS
environment variables for all variable storage. If this option, NSH
will also support local NSH variables. These variables are, for the
most part, transparent and work just like the OS environment
variables. The difference is that when you create new tasks, all of
environment variables are inherited by the created tasks. NSH local
variables are not.
If this option is enabled (and CONFIG_DISABLE_ENVIRON is not), then a
new command called 'export' is enabled. The export command works very
must like the set command except that is operates on environment
variables. When CONFIG_NSH_VARS is enabled, there are changes in the
behavior of certains commands

If CONFIG_NSH_CONSOLE is set to y, then CONFIG_NSH_ALTCONDEV may

to support the NSH console. If CONFIG_NSH_ALTCONDEV is selected,
then NSH_ALTSTDIN, NSH_ALTSTDOUT and NSH_ALTSTDERR must be set

This may be useful, for example, to separate the NSH command
line from the system console when the system console is used to
provide debug output.
Default: stdin, stderr and stdout (probably "/dev/console")
NOTE 1: When any other device other than /dev/console is used
for a user interface, (1) linefeeds (\n) will not be expanded to
carriage return / linefeeds (\r\n). You will need to set
your terminal program to account for this. And (2) input is
not automatically echoed so you will have to turn local echo on.
NOTE 2: This option forces the console of all sessions to use
NSH_ALTSTD(IN/OUT/ERR). Hence, this option only makes sense for
a system that supports only a single session. This option is,
in particular, incompatible with Telnet sessions because each
Telnet session must use a different console device.
