Move the program to the electron application directory 18 | 4. run 19 | 20 | 21 | ### Compatibility test 22 | 23 | - Windows / Typora 1.9.5 PASSED 24 | - Ubuntu / Typora 1.9.3 PASSED 25 | 26 | Since macos may adopt different packaging methods and webkit as the execution environment, this tool does not support applications under macos. 27 | 28 | ### Examples 29 | 30 | https://github.com/DiamondHunters/NodeInject_Hook_example ：Use NodeInject with Typora 31 | 32 | ----------------------------------------- 33 | ### Digression 34 | First airdrop of my life.
