tagJumper.sh

#!/bin/bash

# takes a tag like "AssessmentService" or "User" - checks the tags file for
# a single exact match. If found, jump to it. Else, default to normal Vim behavior.
#
# (basically NeoVim is stupid; searching for a tag "User" via the :ta command 
# often searches for other tags with "User" in the name like "UserRepository" or
# whatever (interestingly, CTRL-] seems consistently good!). This was enver a problem
# in old Vim, at least that I can recall.
#
# This script is part of a workaround -- if it finds a single exact match it jumps
# right to it. Otherwise returns a non-zero exit code, and the VimScript hooking into
# this falls back to default behavior.

# step 1 - did they ask for a tag?
if [ -z $1 ]; then
	echo "No tag specified; exiting..."

# step 2 - look in this directory and in any parents for a .tibsJsonTags file.

baseDir=`find-up .tibsJsonTags`

if [ "$baseDir" == "" ]; then
	# no json tags file found
	echo "No .tibsJsonTags file found; exiting..."
	exit 1

# step 3 - check the tags file for an exact match.
