#9723: Give Tab warning only once per file -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: feature request | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.9 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Currently, when compiling a tabbed file, GHC spits out a huge number of warnings: {{{ Main.hs:1:1: Warning: Tab character [..] Main.hs:89:1: Warning: Tab character Main.hs:90:1: Warning: Tab character Main.hs:91:1: Warning: Tab character Main.hs:92:1: Warning: Tab character Main.hs:99:4: Warning: Tab character Main.hs:100:4: Warning: Tab character Main.hs:101:4: Warning: Tab character }}} This is annoying and not very nice to our users. I suggest to replace it by {{{ This file contains tabs (e.g. line n column m); please use spaces instead }}} or (to be nice to tools that parse this output) {{{ Main.hs:1:1: Tab found here, and in n further locations. Please use spaces instead. }}} (This is clearly a low priority request, but also possibly some low- hanging fruit for new contributors.) -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9723> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

This is good, but there should be way to unsubscribe from a bug as well. Also, and I’m not sure if this is the same thing or not, if I put myself in the “Observer” list (possibly wrong translation), I cannot undo that. Generally, we might give our users more permissions, e.g. to edit ticket descriptions (and not just the summary). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8881> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

I believe, at the time, I meant with an error as described in #8620. As I've just elaborated there, I believe the case for me was that I encountered this without touching any files after typing 'make', which, according to the wiki, is probably a bug in the build system. In any case I haven't seen this in a long time. I just build 7.10.2 rc with make -j5 and had no problems. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7651#comment:18> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
