In Guile 1.4.x, i just installed this: * for scripts with -e ENTRY-POINT, exit value is ENTRY-POINT retval Previously, ENTRY-POINT retval was ignored; scripts would always exit successfully (exit value of zero) unless ‘exit’ was called explicitly.
This change is backward compatible if you explicitly call ‘exit’; there is no change in behavior. On the other hand, if ENTRY-POINT blithely returns #f or a non-zero integer, that value is no longer masked; the script will now exit failurefully. This change removes the small but gratuitous conceptual discrepency between C ‘main’ and Scheme ENTRY-POINT, making ENTRY-POINT easier to use internally, generally (caller no longer needs to catch ‘quit’). In Guile 1.4.x, all scripts/* programs use ‘HVQC-MAIN’, which does ‘exit’ explicitly. The other big corpus of scripts i have experience with is ttn-do, which used to use ‘HVQC-MAIN’, but now (with the intent of porting to Guile 2) uses a simpler mechanism that generally does NOT do ‘exit’ explicitly. What do people think of making this change in Guile 2.x and 1.8.x? (Included in the change would be an audit/update of bundled scripts.) thi
