You can add custom syntax definitions to Textastic by using TextMate bundles or Sublime Text packages. See

https://www.textasticapp.com/v9/manual/customization/custom_syntax_themes_templates.html

A quick search for "Kotlin tmbundle" in Google brought up this TextMate bundle which should work:

While the iOS app has a complete manual, the macOS version of Textastic currently does not really have a proper manual, sorry.

Are you looking for any particular information?

I was hesitant to implement this because you could potentially delete all your data using that.

For example, you could search in your iCloud Drive folder using a regular expression search for something like ".*" that matches all text and replace it with an empty string.

I guess that is true for all other text editors, too, that implement this, but it might still be a nightmare for a user if and when this happens.

I'll consider adding replace in multiple files if I get enough people asking for this feature.

I can reproduce the issue on my iPad.

Thanks a lot for reporting this issue. This is the first time I hear about it.

It almost looks like the iOS system keyboard disables my custom inputAccessoryView for a short moment after entering a key.

I'll try to find out what's going on and hope that I can find a workaround.

Textastic 9.8 with support for Find in Files was released today.

You can find more information in the manual at https://www.textasticapp.com/v10/manual/managing_files/find_in_files.html

Textastic should do the same as your command line. Textastic uses libssh2 instead of OpenSSH, but that should not matter.

Here are a few things we could try:

1. Please send me a screenshot of your connection's settings in Textastic. Maybe I can spot a problem.

2. You could generate a new public/private key file pair and send the two files to me. I could then try to add it to my server and connect to it from Textastic to see if your keys work in general. I can then send you screenshots of my configuration.

You can send me the key files (e.g. id_rsa and id_rsa.pub) by email to support@textasticapp.com

3. It that still doesn't help, you could add the public key to your server and give me the login details. I can then try to connect to your server from Textastic on my device.

Can you successfully connect to your server from your Windows PC using the user name and the generated key file? Maybe with PuTTY or ssh in a WSL terminal?

I also think that the host name at the end of the line of the public key does not matter. 

Are you 100% sure that the user name is correct? Maybe there is an invisible character like space before or after the name? Please try to delete the user name and enter it again. 

Another idea: can you have a look at the SSH server logs?

Ok, I tried it with the following command line on my Mac:

ssh-keygen -m PEM -t rsa -b 4096

I saved the key as ~/ssh/id_rsa_test without a passphrase.

I transferred the key file "id_rsa_test" using AirDrop to my iPad and selected the Files app as the AirDrop target. I put the file into "On my iPad/Textastic/ssh/".

I added the contents of "id_rsa_test.pub" to ~/.ssh/authorized_keys on the server for the user I'm trying to log in as.

On my iPad in Textastic, I enabled public key auth for the connection and used "/ssh/id_rsa_test" as the private key file path.

I could then successfully connect to my server using the SSH terminal and using the SFTP connection.

Here is what you can try: go to the File Transfer screen, edit the connection and enable "Debug Log". Then try to connect to the server using SFTP and have a look at the log file.
