#10021: Add "Error:" prefix for error-messages -------------------------------------+------------------------------------- Reporter: k-bx | Owner: Type: feature request | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.8.4 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by hvr): I'd like to propose to change the case of `Error` and `Warning` to lower case to match the convention as used by the most popular C/C++-compilers these days. For reference, this is what `gcc` currently does: {{{ $ gcc -Wall -c foo.c foo.c: In function ‘main’: foo.c:2:1: warning: control reaches end of non-void function [-Wreturn- type] int main() { } ^ }}} {{{ $ gcc -Wall -Werror -c foo.c foo.c: In function ‘main’: foo.c:2:1: error: control reaches end of non-void function [-Werror =return-type] int main() { } ^ cc1: all warnings being treated as errors }}} and here's what `clang` does: {{{ $ clang-3.5 -Wall -c foo.c foo.c:2:18: warning: unused variable 'x' [-Wunused-variable] int main() { int x = 0; } ^ 1 warning generated. }}} {{{ $ clang-3.5 -Wall -Werror -c foo.c foo.c:2:18: error: unused variable 'x' [-Werror,-Wunused-variable] int main() { int x = 0; } ^ 1 error generated. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10021#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
