Open WebStorm files through the command line using Git Bash on Windows.

wstorm.sh

#!/bin/bash
#
# Opens WebStorm from the command line using Git Bash for Windows.  If you're 
# working within the integrated terminal in WebStorm, this will open the file
# passed in using just the relative path. If the file specified doesn't exist,
# it creates it and opens it.  Just copy wstorm() into wherever you keep your 
# Bash aliases and make sure you change your Terminal path to Git Bash (see 
# Notes section).
#
# ------
# Notes:
# ------
# If you want this to work in WebStorm, you have to change the terminal path in
# Tools > Terminal to the following (quotes included):
# "C:\Program Files\Git\bin\sh.exe" -login -i
# If you have 32-bit Git installed, add " (x86)" to "Program Files".
# FYI, I got this working with version 2016.3.2.
#
# -----------------
# From the website:
# -----------------
# In order to open a file from WebStorm through the command line, the format
# needs to be as follows:
# <WebStorm> <path1> --line <number> <path2>
# where:
# <WebStorm> is the platform-specific product launcher
# <path1> is the path to the project that contains the desired file
# <number> is the number of the line, where the caret should rest
# <path2> is the path to the file to be opened
