Retro 11.4

Compatibility Issues

This release brings several changes that may require small alterations to existing source code.

First, the files' vocabulary is now in the library and not the core language. For most users, adding a single line to the start of their sources will be sufficient.

needs files'

The second change is more significant. We have moved pow, abs, min, max, and random to the math' library. If you have source using these, you need to add the following to your sources:

needs math'
with  math'

If you don't want to do with math', you can add a ^math' prefix to each use of these functions and just use the needs math' line.

Third, hidden headers are no longer preserved. There is a new function, HEADERS, which returns the maximum number of hidden headers. Exceeding this will cause problems, so it can be revectored to increase (or decrease) as needed.

Fourth, the tib, temporary string buffers, and hidden headers are now moved to the end of physical memory. Use the introspection' library to determine the size and actual locations of these buffers, and avoid overflowing into them. E.g., in casket', we use ^introspection'startOfBuffers to identify the start of the buffers and dynamically shift the casket buffers to a safe location.

Fifth, string constants are now created using string: instead of string. This requires a quick search/replace to fix.

Retro 11.3

Compatibility Issues

This release of Retro brings a number of changes that may require small alterations to existing sources. Specifically:

  • maximum string length is now 256 cells by default
  • hidden functions are no longer revectorable

The first is not a big deal. It's now possible to alter both the maximum string length and the number of temporary buffers. To restore a 512 cell size as in 11.2:

here 512 allot constant <512-TIB>
[ <512-TIB> ] is tib
[ 512 ] is STRING-LENGTH

The second change shouldn't be too critical. Basically it means that this will no longer work:

{{
  : foo  ( - ) 50 ;
---reveal---
  : bar1  foo foo + ;
  [ 100 ] is foo
}}

Any private definitions are no longer revectorable. If you have no ---reveal--- in a namespace, all functions are non-revectorable. This won't break anything in the standard language or libraries, but could be a problem if you rely on the old behavior in your code.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
