Hello, there is a Vue.js Sublime Text 3 syntax definition at:

https://github.com/vuejs/vue-syntax-highlight/tree/new (it's important to use the "new" branch, not "master" or "st4")

Please have a look at the manual to see how you can add custom syntax definitions using Sublime Text packages:
https://www.textasticapp.com/v9/manual/customization/custom_syntax_themes_templates.html

Just adding the file "Vue Component.sublime-syntax" to "Local Files/#Textastic/Vue" and reloading customizations should work and you'll have "Vue Component" as a new syntax definition.

Here is a screenshot of how the included "samples/basic.vue" file looks for me in Textastic:

Is Safari your default browser? Some browsers like Brave do not support localhost http urls. 

I had disabled this since there were some issues with the notch and safe are insets on iPhone I could not resolve at that time. I'll probably need to give it another try.

As a workaround, you can use the "Preview in Safari" feature to show a web preview in landscape mode on iPhone:

Not all file providers support being added as external folders to Textastic.

Currently, this works with folders in "On my iPad/iPhone", iCloud Drive, Working Copy (Git client), and Secure ShellFish (SFTP client).

This is a feature Google would have to add to their Google Drive app.

You can find more information about external folders in the manual at:

https://www.textasticapp.com/v10/manual/integration_other_apps/external_files_folders.html#adding-external-folders

As an alternative you can use Textastic’s built-in Google Drive client to download whole folder hierarchies.

I don't use Nextcloud myself, but the Nextcloud app includes a file provider, so you can add it as a location in the Files app. Then, you have the following options:

• Use the "Open…" command in Textastic to open a file using the iOS document picker
• Use the "Share" command in the Files app and select Textastic to open the file in Textastic
• Drag a file from the Files app to Textastic to open it
• It might also be possible to share directly from the Nextcloud, but I'm not sure if their app supports it

You can find more information about external files in the manual: https://www.textasticapp.com/v9/manual/integration_other_apps/external_files_folders.html

Currently not, sorry. Thanks for your suggestion. I'll consider it for a future update.

Hello,

unfortunately this is not currently possible in Textastic for macOS. It could be done with regular expression search and replace, but this is not yet implemented, sorry.

Hello,

do you maybe have a different default browser set than Safari? Not all third party browsers support localhost links (for example Brave doesn't support them). 

See https://support.apple.com/en-us/HT211336

I can reproduce the issue when trying to use "Create External File" with OneDrive.

This looks like a bug in the OneDrive file provider that is out of my control. 

I tested it successfully with Dropbox, iCloud Drive, "On my iPad" and Working Copy - only OneDrive seems to have this problem.

Thanks for the logs, I'll try to reproduce it.
