Pursuant to the post below, I found myself creating a simple Scala bundle for Textmate, as there isn’t one at the moment. (Getting in on the ground floor!)
The Textmate snippet system is a wonderful creation — simple, delightful, and helpful. Unfortunately, the templating system is not nearly so nice — just a Perl one-liner to substitute in some environment variables, and no snappy tab-tab autofill magic.
Then I ran across this great post by Henrik Nyh, in which he scrapes together a little Applescript to create a Textmate template as a snippet.
However, I found myself wanting both some templated boilerplate, with variable substitution, and some snippetized text below. This proved a little trickier than I first thought, since the Applescript inserts at the top of the document, and it would require a nasty keypress script to insert the snippet below.
So, I came up with a slightly modified version of Henrik’s system, which supports a template_in.txt file with the usual variable substitutions, as well as a snippet below.
The template script looks like this:
if [[ ! -f "$TMNEWFILE" ]]; then
TMYEAR=date +%Y \
TMDATE=date +%Y-%m-%d \
TMUSERNAME=niutil -readprop / /users/\$USER realname \
TMTEMPLATEOUTPUT=$(mktemp “/tmp/tmtemplate_XXXXXX”)
perl -pe ’s/\${([^}]*)}/$ENV{$1}/g’ \
< templatein.txt > “$TMTEMPLATE_OUTPUT”
touch “$TMNEWFILE”
{ # Insert the template & snippet!
osascript "${TM_BUNDLE_SUPPORT}/load_snippet.scpt" "$TM_TEMPLATE_OUTPUT" "snippet.txt"
} &>/dev/null &
fi
and the Applescript is modified to this:
on run args
set templateoutputfile to (item 1 of args)
set snippet_file to (item 2 of args)
-- retrieve the template and snippet text
set existing_text to read (POSIX file (template_output_file)) as «class utf8»
set loaded_snippet to read (POSIX file (snippet_file)) as «class utf8»
-- insert both into the document
tell application "TextMate"
insert existing_text
insert loaded_snippet with as snippet
end tell
-- remove the temporary file
do shell script "rm \"" & template_output_file & "\""
end run
