Project Grep Buffer Filled With Cruft

[trishume]

When using projectile grep (SPC p g) it creates a grep buffer that includes a 10 line find grep pipeline, which means you can't see any results unless you scroll down. That brings me to the second problem: the buffer isn't focused by default, so you have to switch to it before you can scroll down.

Ideally the find command should be hidden and the buffer should be selected by default. I'll try to fix this myself if this is something that you never use.

Here's the cruft that is printed, except the one long line wraps into around 20 lines:

It would be a great improvement!

I do use it with <SPC> e n (next error) to go to the next occurence and switch explicitly to the window with <SPC> windows num if I want to browse the occurence without going to each location. If nothing is useful I close the popup with <SPC> w p (window popup), you can also use <SPC> w u to "undo" the layout and go back to the previous one.

There is a caveat, when the grep buffer is selected and I hit enter to go to a specific occurence, a new window is opened instead of reusing a current window. It annoys me a lot. This behavior does not appear with <SPC> n e which may be a good pointer to find a solution to this.

Indeed, autofocus with reuse of opened window would be a lot better.

I wonder if there is a mode to get the results in a helm buffer.

I created PR for adding helm-projectile-grep/ack/ag in Projectile. You can have a look here. It could be a better alternative.

@Thudo very interesting, I will watch this. We have also to be sure that Windows users can still be able to find files in their projects.

@syl20bnr (helm-)projectile-find-file works fine on Windows. As for grepping, I can confirm it works properly if you setup cygwin/mingw correctly that Emacs can use proper Linux utilities.

[syl20bnr]

Great news!

[tuhdo]

Fyi, the change has been merged.

[syl20bnr]

I consider this a non-issue now we have better solutions than grep.
