Flymake produce temp file without cleaning it up

[ArthurTu]

If I edit a file named a.hs, it takes a long time to start haskell mode. And a file named a_flymake.hs is created on that directory without asking me. It stands there even after i closed a.hs.

I do not have ghc installed in my host os. So haskell-program-name is not set in my .emacs. Check if this is related to the bug.

However, i want to use emacs to edit haskell files with hilight and indent features.

I think codes about flymake should be written into a function instead of being a default feature. If somebody want to enable it, just that to the haskell-mode-hook.

I have to dive into haskell-mode.el and comment the last few lines to disable flymake. That is embarrassing and dirty.

[ivan-m]

There's probably some configuration issue going on here; I don't have any flymake files or buffers being created for me when I use haskell-mode :/

Can you put your config up somewhere?

I do not have any special configuration for flymake or haskell.

Haskell is auto-loaded by package-initialize().

Flymake didn't annoy me, since i comment on below lines.

;; (eval-after-load "flymake"
;;   '(add-to-list 'flymake-allowed-file-name-masks
;;      '("\\.l?hs\\'" haskell-flymake-init)))

I looked up flymake on emacswiki, and try to add flymake-simple-java-cleanup after haskell-flymake-init, but it didn't work.

I do use flymake on other modes like flymake-python. However, these flymake-modes rely on flymake-easy. They are configured differently from native flymake.

[ivan-m]

So, we should have the flymake support for haskell-mode explicitly optional rather than automatically being enabled if flymake is detected?

[ArthurTu]

haskell-mode turn on flymake, even though i do not have any cmd like "hlint" or "ghc -fno-code" in my system.

flymake-css will produce an error

Not enabling flymake: 'csslint' command not found

if i do not have csslint installed. Flymake won't be turned on in css-mode.

Maybe i should learn some config of flymake and fix it myself, so that i can provide a patch.

[chrisdone]

Can someone who uses flymake take ownership of this issue and assign a priority according to #145. Thanks.

[gracjan]

Lets agree to use flycheck instead of flymake, flycheck is better at handling temporary files.

[terlar]

Perhaps this could be revisited with the new and improved flymake version.

[carlosdagos]

As far as I can see, flycheck never made it? :(

[codygman]

I don't think it did @carlosdagos, but it seems the temp file junk endlessly created by flymake defaults is fixed by this code.
