Changes required due to TextBuffer.save becoming async in Atom 1.19

[maxbrunsfeld]

Hi! Thanks for maintaining the build package!

In Atom v1.19, we will release a major change to Atom's core text buffer data structure. As part of this change, we have made TextBuffer.save asynchronous; rather than blocking until the save is complete, it now immediately returns a Promise that resolves when the save is complete. Because of this, a few other Atom APIs that use save have similarly become async:

• Pane.close
• TextBuffer.save
• TextEditor.save
• Pane.saveItem
• Pane.saveItemAs
• Pane.saveActiveItem
• Pane.saveActiveItemAs
• Pane.saveItems
• Workspace.saveActivePaneItem
• Workspace.saveActivePaneItemAs

Effects on this package

We think this package could be impacted by this upgrade because it calls the changed methods in the following places:

• TextEditor.save
  • here
  • here

We found these calls using a regex search, so this list might be incomplete, and it might contain some false positives.

What to do about the change

It should be pretty easy to adjust your package code and/or tests to work with the new async behavior, and to simultaneously keep it working with older versions of Atom. Here are some examples of pull requests we opened on our bundled packages to cope with the change:

• https://github.com/atom/autocomplete-plus/pull/852
• https://github.com/atom/whitespace/pull/155
• https://github.com/atom/symbols-view/pull/222
• https://github.com/atom/status-bar/pull/193
• https://github.com/atom/tabs/pull/448

Please let me know if you have any questions. I'd be happy to help!
