Update older versions¶

Versions before 0.105.0¶

Tatin Version 0.105.0 introduced the ]Tatin.Update user command.

To update an earlier version:

1. Remove Tatin/ from the MyUCMDs/ folder. (See Enable the API.)
2. Download and install Tatin from scratch. (Also Cider, if you are using it.)
3. Review your setup.dyalog script if you are using one.

OneDrive and versions before 0.114.0¶

OneDrive is cloud storage provided by Microsoft for backing up your personal folders. A Windows user JohnDoe who enables OneDrive changes his Documents folder:

C:\Users\JohnDoe\Documents\             ⍝ from
C:\Users\JohnDoe\OneDrive\Documents\    ⍝ to

The Dyalog installation folder is (by default) in the Documents folder, e.g.

Dyalog APL Files                  ⍝ version-agnostic
Dyalog APL-64 19.0 Unicode Files  ⍝ version-specific

Before version 0.114.0, Tatin read environment variable USERPROFILE to find the Documents folder. But USERPROFILE does not reflect use of OneDrive! An update of Tatin would apparently succeed but, written to the wrong Documents folder, would not appear in subsequent launches of Dyalog.

Since version 0.114.0, Tatin uses the experimental I-beam 4070⌶0 to recognise a Documents folder in OneDrive.

If you are using OneDrive and a version of Tatin older than 0.114.0:

1. Determine your Tatin home: the relative path from your OneDrive Documents folder in which your Tatin files are kept, i.e.

   <dyalog-install-folder>/SessionExtensions/CiderTatin
   

2. Add to SALT's cmddir the path

   C:/Users/<⎕AN>/OneDrive/Documents/<tatin-home>
   

   See ]SALT.Settings -?? for help.

3. Remove from SALT's cmddir the path

   C:/Users/<⎕AN>/Documents/<tatin-home>
   

4. Remove from your file system folder

   C:/Users/JohnDoe/Documents/<tatin-home>
   

Updates will then work as expected.
