1dde5fa2 | 11 | * Parse value of the argument to the "filter" keyword. |
25ec7bca JH |
12 | * On the command line this looks like: |
13 | * --filter=<arg> | |
14 | * and in the pack protocol as: | |
15 | * "filter" SP <arg> | |
16 | * | |
17 | * The filter keyword will be used by many commands. | |
18 | * See Documentation/rev-list-options.txt for allowed values for <arg>. | |
19 | * | |
20 | * Capture the given arg as the "filter_spec". This can be forwarded to | |
21 | * subordinate commands when necessary. We also "intern" the arg for | |
22 | * the convenience of the current command. | |
