I got thankfully introduced to use helm and helm-projectile for all the goodies it has and especially the
helm-projectile-grep-search. I must say, this supercharged Emacs by a long shot. I learned that from this great tutorial : http://tuhdo.github.io/helm-projectile.html. Unfortunately, everyhting else was fine except grep search-related commands, they throwed this error by invoking them on my machine:
Error during redisplay: (eval (helm-show-candidate-number (car-safe helm-mode-line-string))) signaled (wrong-type-argument integer-or-marker-p nil) [6 times]
Error running timer helm-projectile-grep-or-ack: (wrong-type-argument stringp nil)
The same error was issued when I used
C-u C-s recursive grep search while in
helm-find-files bound to
C-x C-f. I run this on marked files with
rgrep works well which is built in Emacs (see image below). So I don't know what am I missing to get grep search work.
Machine: Windows 7 32bit.
Helm/Projectile/Helm-projectile all updated from MELPA.
I have installed Cygwin and added to Path:
