e / TextMate Command - Open Target Document

[UPDATED: Saturday, March 08, 2008 at 10:26:56 AM]

I've been playing around with e - TextEditor this weekend to see if maybe it'll replace Textpad for me. I've always liked the speed of Textpad and it does a really good job on large files. I use Eclipse as my main IDE, so when it comes to a Notepad replacement my two main requirements are fast load times and the ability to handle large text files (for reading logs.)

However I keep seeing some of the really cool things that TextMate can do, so I've been keeping an eye out on e - TextEditor. It has a couple of features that would make quick editing of HTML files extremely easy. I really like the ability to selected a bunch of words or tags in a document and easily replace them.

One of the key features of e is it's TextMate bundle support—which really allows you to extend the functionality of the program. While surfing the e forums, I came across a Bundle command which allows you to open the file you have selected in the document (or the file where the caret is positioned.) This script makes it really easy to open files being loading from <script />, <style /> or any other tag you may use for loading files.

The original script, posted by tanguyr, I found either needed you to add e.exe to the Windows PATH environment or you needed to hard code the path to e.exe. I fixed the problem by using one of e's environmental variables. The $TM_SUPPORT_PATH variable points to a sub-directory above where the e.exe file exists, so I just use a relative path to get to the e.exe executable.

To add this command to e, go to the Bundles > Edit Bundles > Show Bundle Editor. I added this script to the Source bundle, as it seemed to make the most sense to me. Select the Source folder and click the + button and select the "New Command" option. I decided to call the command "Open Target Document", if you don't like the name choice something you like better.

Paste the following Bash script into the source area.

#split the current line in two: before and after cursor
LN_BEFORE=${TM_CURRENT_LINE:0:$TM_LINE_INDEX}
LN_AFTER=${TM_CURRENT_LINE:$TM_LINE_INDEX}

#the part of the line before from the last double quotes
#to the end plus the part of the line after from the start
#up to the first double quotes = the target href
TARGETREF=${LN_BEFORE##*\"}${LN_AFTER%%\"*}

#for every "../" at the start of the target href, go "up"
#one story in TM_DIRECTORY (i.e. remove rightmost dir)
while [[ "$TARGETREF" =~ "^\.\./.*$" ]]
do
 TM_DIRECTORY=${TM_DIRECTORY%/*}
 TARGETREF=${TARGETREF#../}
done

# if the directory path ends with a slash, then don't append one
if [[ $TM_DIRECTORY =~ /$ ]]; then
    #the absolute path to the target file, in cygwin notation
    ABSPATH=${TM_DIRECTORY}${TARGETREF}
else
    #the absolute path to the target file, in cygwin notation
    ABSPATH=${TM_DIRECTORY}/${TARGETREF}
fi

#test if the file exists
if [[ ! -f "$ABSPATH" ]]; then
 echo file $ABSPATH does not exist >&2
 exit 1
fi

#change cygwin style path to windows style path,
#and call e to open file
if [[ "$ABSPATH" =~ ^//(.*)$ ]]; then
  # get the path to the file to edit
  WINPATH=${ABSPATH//\//\\}
  echo "WINPATH=$WINPATH"
  # invoke "e/Textmate" from the command line and open the file
  "$TM_SUPPORT_PATH\\..\\e" "$WINPATH"
elif [[ "$ABSPATH" =~ /cygdrive/([a-z|A-Z])/(.*)$ ]]; then
  # get the path to the file to edit
  WINPATH=${BASH_REMATCH[1]}":\\"${BASH_REMATCH[2]//\//\\}
  echo "WINPATH=$WINPATH"
  # invoke "e/Textmate" from the command line and open the file
  "$TM_SUPPORT_PATH\\..\\e" "$WINPATH"
else
  echo $ABSPATH is not a cygwin path? >&2
  exit 1
fi
