Installation instructions

[rigon]

Can you provide installation instructions?

I'm struggling to install the parser.
What I've done so far:

• Install OCaml
• Install opam
• Install OASIS: opam install oasis

Then, I ran ./configure and I got errors related with absolute paths to your home folder. I've found that in file setup.data. Removing this file seems to fix the problem.

But then I've got this error:

E: Cannot find findlib package 
E: Cannot find findlib package elements
E: Cannot find findlib package ppx_deriving.std
E: Cannot find findlib package sedlex
E: Failure("4 configuration errors")

Hey, thanks for interest in the parser! I'll update the build instructions and will let you know once it's working! ;)

Hi! So before I explain you how to install the package, here's a brief overview of current status:

I am working in parallel on the implementation of the language (fold-lang/fold and the separate parsing library called pratt, used by the language (this repo of course).

At the moment they are a bit out of sync. The parser is working and implements a basic macro system. But the main repository fold-lang/fold is still under active development. I'm essentially trying to merge two efforts and use pratt in fold as a library.

Now, about the installation instructions: You can add the fold package repository to opam and directly install the parser:

• $ opam remote add -k git fold https://github.com/fold-lang/repository
• $ opam install pratt
• $ test_fold
• $ fold

This should show you the testing interpreter for the parser. You can ask for help with \h and write expressions followed by Ctrl+D.

Let me know if this works and once again thank you!

Note: I only tested this with the latest OCaml version 4.04.

Here is an examples of what's working:

-> x = 1
-> 2 + 2
-> sum = x y -> x + y
-> sum 2 2 - 1
 = 3
