/* |

|
|
This command line tool is currently merely for development and testing |
16 |
|
|
purposes, regarding the real-time instrument script feature of the sampler. |
17 |
|
|
You can use this command line application like this: |
18 |
|
|
|
19 |
|
|
ls_instr_script < src/scriptvm/examples/helloworld.txt |
20 |
|
|
|
21 |
|
|
Which will peform 3 things: |
22 |
|
|
|
23 |
|
|
1. Parses the given instrument script and prints any parser errors or |
24 |
|
|
warnings. |
25 |
|
|
2. It dumps the parsed VM tree (only interesting for LS developers). |
26 |
|
|
3. If there were not parser errors, it will run each event handler defined in |
27 |
|
|
the script. |
