LeMP-repl

LeMP-repl is a super simple interactive program that that reads unprocessed EC#, LES v2 or LES v3 code as input and produces processed or unprocessed EC#, LES v2 or LES v3 code as output.

Here's what LeMP-repl looks like in action:

Easy, right? It's just a simple tool that makes it much easier to look at and reason about EC# syntax trees.

Build instructions

LeMP-repl is fairly straightforward to build. Just do this following:

$ nuget restore
$ msbuild /p:Configuration=Release

Technologies

• LeMP-repl is mostly just a wrapper around David Piepgrass' amazing Lexical Macro Processor (LeMP) and Enhanced C# (EC#) parser, both of which can be found here.

• LeMP-repl uses Pixie for option parsing and error logging.

LeMP-repl tries to fulfill a simple use case, so there aren't a lot of options. Here's a full list, adapted from --help:

Input and output

  Selects an input language, which can be either ecs, les, les2 or les3. By default, the input language is ecs.

  Turns off macro processing by LeMP.

• --output-language=⟨language⟩, -o⟨language⟩

  Selects an output language, which can be either cs, ecs, les, les2 or les3. By default, the output language is les.

Overall options

• --help, -h, -?
