autogen usage

[ddemidov]

Hi,

I am looking at converting the python bindings to using the autogen scripts. For now I am just trying to run the existing scripts. Unfortunately, the usage instructions do not work for me: https://gist.github.com/ddemidov/3b97a533a149491c7006

Do I need anything else for autogen to work?

You're the first person (as far as I know) to test this in it's current state, so there may be some issues (sorry!).

Can you try again (pull upstream changes first)? I think the problem was that I hadn't fully removed some bad scripts from the fork of the library that our autogen package tries to install. Because it is installing from a git repo instead of from NPM itself, NPM doesn't automatically run the build scripts, so I had to configure it manually (and the issue was in that custom configuration).

I also made some changes to the autogen readme so that it's more understandable.

This manages to get further, but npm install still ends with an error: https://gist.github.com/4164b089de53f82c752e

@ddemidov Sorry for the late reply, I was very busy and completely forgot to reply to this thread.

I think I have fixed all the issues (and I have tested it on multiple clean installs of the OS). The problem appears to be how npm ran my scripts: the module was installing and running the prepublish script, which would run the compile script, which would try to install some dependencies, which would trigger the prepublish again and create an infinite loop. It should be fixed now -- and thanks for your patience!

It works! Thank you, I'll continue my experiments with autogen.

The following command runs fine:

$ node autogen.js 
4 files found
Completed processing file "js/extras.ts"
Completed processing file "js/motor.ts"
Completed processing file "js/sensor.ts"
Completed processing file "wrapper-specification.md"

If, however, I modify an autogen block inside one of the generated files (for example

diff --git a/extras.ts b/extras.ts
index 8e3338f..29784d0 100644
--- a/extras.ts
+++ b/extras.ts
@@ -3,7 +3,6 @@
 ///<reference path="io.ts" />

 //~autogen autogen-header
-    // Sections of the following code were auto-generated based on spec v0.9.2-pre, rev 1. 
 //~autogen

 class PowerSupply extends Device {

), then node autogen.js results in the following error:

$ node autogen.js 
4 files found
Completed processing file "js/motor.ts"
Completed processing file "js/sensor.ts"
Completed processing file "wrapper-specification.md"
Error processing file "js/extras.ts": Error: ENOENT, open 'js/extras.ts'

It seems that autogen does not overwrite a file if its contents did not change, but fails when there are some changes to apply.

[ddemidov]

The error above does not happen when node is run from the top level directory:

$ node autogen/autogen.js 
4 files found
Completed processing file "js/motor.ts"
Completed processing file "js/sensor.ts"
Completed processing file "wrapper-specification.md"
Completed processing file "js/extras.ts"

Is that the intended behavior?

@ddemidov Feel free to reopen this if you come across any more issues.
