The Trick::CommandLineArguments class stores the command line arguments specified
|
||
|
|
by the user when starting the simulation. The class provides routines to
|
||
|
|
access the arguments.
|
||
|
|
|
||
|
|
### Accessing the Command Line Arguments
|
||
|
|
|
||
|
|
The command line arguments are available to user classes through the following two calls.
|
||
|
|
|
||
|
|
```
|
||
|
|
int command_line_args_get_argc() ;
|
||
|
|
char ** command_line_args_get_argv() ;
|
||
|
|
```
|
||
|
|
|
||
|
|
Specific directories and file names may be accessed by the following calls.
|
||
|
|
|
||
|
|
```
|
||
|
|
const char * command_line_args_get_output_dir() ;
|
||
|
|
const char * command_line_args_get_input_file() ;
|
||
|
|
const char * command_line_args_get_default_dir() ;
|
||
|
|
const char * command_line_args_get_cmdline_name() ;
|
||
|
|
```
|
||
|
|
|
||
|
|
### Modifying the Output Directory
|
||
|
|
|
||
|
|
By default the RUN directory of the input file is the output directory. To change this
|
||
|
|
specify the <tt>-O</tt> or the <tt>-OO</tt> command line arguments.
|
||
|
|
|
||
|
|
```
|
||
|
|
S_main_${TRICK_HOST_CPU}.exe RUN_dir/input.py -O <output_dir>
|
||
|
|
```
|
||
|
|
|
||
|
|
All Trick core output files will be written to the specified <output_dir>.
|
||
|
|
|
||
|
|
### TimeStamping the Output Directory
|
||
|
|
|
||
|
|
The user may also specify a time stamped output directory in the input file.
|
||
|
|
|
||
|
|
```
|
||
|
|
trick.output_dir_timestamped_on()
|
||
|
|
```
|
||
|
|
|
||
|
|
This will create a dated subdirectory in the current output directory. All of the Trick
|
||
|
|
core output files will be written to the output directory. This option may be used in
|
||
|
|
conjunction with the <tt>-O</tt> or the <tt>-OO</tt> command line arguments.
