I work for an organization that does a lot of work with government data.  We have a couple of different projects where we've abstracted out common text search/manipulation operations into reusable libraries, for things like standardizing the way politicians' names are displayed (e.g., transforming MCDONALD, BOB (R-VA) into Bob McDonald (R-VA)), or finding legal citations in text (e.g., finding a reference to (e.g., finding occurrences of things like 1 U.S.C. 7 in text, determining that it's a US Code citation, and returning a structure that says it's referring to section 1 of title 7).  These are relatively simple operations, and lots of collaborators in our space would like to use them, but we end up having to pick a language in which to implement each (the former is in Python; the latter, Javascript), and we freeze out potential consumers/contributors who work in different languages and don't want to resort to hacks like shelling out to a node process to handle their text.  This all seems like a shame because what we're expressing is so simple, and ought, one would think, to be pretty easy to share.What would be ideal would be a tiny DSL that could express a few basic text processing operations: regular expression search/replace, a few list-processing operations like map and filter, and the ability to store stuff in JSON-ish data structures (maps and lists), and a mechanism to either translate this DSL into or allow it to be consumed from the actual higher-level languages we and our collaborators want to work with (Python, JS, Ruby, and PHP are probably the main ones).  Does anything like this exist?I've considered building one myself... maybe a declarative thing on top of something like YAML, or maybe a tiny subset of Scheme or Lua, or maybe something entirely invented for this purpose.  But I wanted to see if anything was already out there first.
Domain-specific language for text search/processing?
