An archive of the ASDL SourceForge repo (imported from CVS)

Archive of ASDL (imported from SourceForge CVS)

Hi! For those of you here in the 20th century, this may appear strange.

This is an archived repo for ASDL: "The Zephyr Abstract Syntax Description Lanuguage".

Most of the interesting parts are in the asdlGen subdir. Not sure what the rest is......

The original academic paper on ASDL was written in 1997.

The code in this repo is incredibly old. The most recent commit was 2002.

It was imported from SourceForge CVS over to Git & Github.

Modern usage

ASDL retains relevance because it is still ued to describe the Python AST.

See this blog post for more details on what ASDL is (and why it's still useful). It is written by the Oil Shell people.

This is the only Git commit actually written by a human. All the other commits were automatically generated from the CVS respository (see below).

Importing

I had to import it to git with cvs2svn 2.5.0 (also supports cvs2git).

The sequence of comands to import was as follows (directly from my shell history):

wget "https://github.com/mhagger/cvs2svn/releases/download/2.5.0/cvs2svn-2.5.0.tar.gz"
tar -tf cvs2svn-2.5.0.tar.gz
tar -xf cvs2svn-2.5.0.tar.gz # Generates a directory called "cvs2svn-2.5.0"
rsync -ai a.cvs.sourceforge.net::cvsroot/asdl/ cvs # Downloads the CVS repo from SourceFourge
cd cvs2svn-2.5.0/
python2 cvs2git --blobfile=../blob.dat --dumpfile=../dump.dat --encoding=utf8 --encoding=latin1 --retain-conflicting-attic-files ../cvs
cd ..
git init asdl-git
cat blob.dat dump.dat | git --git-dir=asdl-git/.git fast-import
# Tada
git log
git status

Then, I wrote this commit (adding a modern readme). This is the last commit there will ever be, because I'm archiving the repo :)
