3.24.0

New features:

• Turn rich compiler errors on by default
• Tweak experimental manifest plugin to return ELP-compatible information

Bug fixes:

• make escriptize reproducible by setting timestamps for files in zip to unix epoch
• Log path when plugin template file read fails
• Prevent infinite compiler DAG growth
• Port Relx compatibility fix for escript files in OTP-27

Internal maintenance:

• Made rebar_utils:filtermap/2 to call directly lists:filtermap/2
• Cleaned up additional definitions in bootstrap
• Replaced rebar_utils:find_source/3 by a call to filelib:find_source/3 and Marked rebar_utils:find_source/3 as deprecated
• Fixing various typos in comments, types, and function names
• Bump hex_core and certifi dependencies
• Remove legacy hostname checks
• Replaced group_by_namespace/1 by a call to maps:groups_from_list/2
• Removed legacy OTP_RELEASE macro statements
• Removed legacy fun_stacktrace usage
• Removed unsused platform_define options
• Standardizing templates indentation

Regarding rich compiler errors, the change is optional.

Given the module:

-module(fake_mod).

-export([diagnostic/1]).

diagnostic(A) ->
    X = add(5 / 0),
    {X,X}.

add(X) -> X.

add(X, Y) -> X + Y.

Calling rebar3 compile can now yield:

...
===> Compiling apps/rebar/src/fake_mod.erl failed
   ┌─ apps/rebar/src/fake_mod.erl:
   │
 5 │  diagnostic(A) ->
   │             ╰── variable 'A' is unused

   ┌─ apps/rebar/src/fake_mod.erl:
   │
 6 │      X = add(5 / 0),
   │                ╰── evaluation of operator '/'/2 will fail with a 'badarith' exception

    ┌─ apps/rebar/src/fake_mod.erl:
    │
 11 │  add(X, Y) -> X + Y.
    │  ╰── function add/2 is unused

and in a terminal supporting color output:

By default, this format is turned on, but can be turned off optionally by configuring values with

{compiler_error_format, minimal}.

If this breaks your tooling, you may want to put it in your global rebar3 config file.
