This was causing issues when running multiple tests, in particular for the modules member: modules were executing much more than once, because each additional test would add duplicates to the list which wasn't reinitialized In particular this was causing issues with my new Exec module getting ran more than once per data.

Hello,
For my personal needs I implemented a new feature:
!(EXEC cmd)to execute a command (with shell) and replace the syntax by its result.This can be useful for automating the generation of a Markdown file, for instance inserting the current date (or, say, a version number):
Project version: !{EXEC bash -c "./get_version.sh"}Date of today: !(EXEC date)It is also possible to escape it; that's how the
readme.mdppis able to process correctly\!(EXEC This will not execute)If there are parenthesis/braces/brackets in the EXEC command, right now it will pose issues because I implemented it using a simple regexp (one would require a grammar to take care of matching parenthesis).
The workaround is to use different delimiters ; there are three available, parenthesis, brackets and braces
\![EXEC echo "A command with different delimitors"]By using the PR #79 I was able to pass all tests, except one (
exec_file) which required to correct a minor bug (see commit 23c23f1)I'm open to any change
