|
| 10 |
|
| 11 | - escape_path() seems wrong?
|
| 12 | - It should really take $ to $$.
|
| 13 | - It doesn't escape newlines
|
| 14 |
|
| 15 | return word.replace('$ ', '$$ ').replace(' ', '$ ').replace(':', '$:')
|
| 16 |
|
| 17 | Ninja shouldn't have used $ and ALSO used shell commands (sh -c)! Better
|
| 18 | solutions:
|
| 19 |
|
| 20 | - Spawn a process with environment variables.
|
| 21 | - use % for substitution instead
|
| 22 |
|
| 23 | - Another problem: Ninja doesn't escape the # comment character like $#, so
|
| 24 | how can you write a string with a # as the first char on a line?
