Get rid of the path to talon from a commandline string on windows find the
|
|
20 |
-c (if it's there) and step past it to after the quote on the first command:
|
|
21 |
|
|
22 |
"g:\program files\talon\talon.exe" -c "gcc -c . . ."
|
|
23 |
^------ Returns a pointer to here
|
|
24 |
|
|
25 |
Take care of the possibilty that there might be spaces in the command
|
|
26 |
if it is quoted.
|
|
27 |
|
|
28 |
A state-machine is flexible but not all that easy to write. Should investigate
|
|
29 |
the possiblity of using the Ragel state machine generator perhaps.
