bundle/backup is needed to make failed reinstalls able to rollback. It
also allows python wheel like functionality, where bundles can be build
on one machine, packaged, and then distributed and installed on other
compatible machines without compilers.
buffer/format-at is to buffer/format as buffer/push-at is to
buffer/push. It allows us to format in the middle of an existing
buffer. Prior, to do this operation and extra buffer creating was
required.
The bundle module contains tools for modifying the contents of
(dyn *syspath*) and providing a common interface for installing
packages (called "bundles").
The functions are:
* bundle/install
* bundle/uninstall
* bundle/manifest
* bundle/do-hook
* bundle/list
* bundle/add-file
* bundle/add-directory
A bundle is a directory that contains any number of source files and
other extra files, as well as a directory "hooks/", which contains a
flat listing of janet scripts. This version of the bundle module is not
responsible for building C source modules or for downloading files over
the network.
Basic frontend being prototyped in examples/sysir/frontend.janet. Still
a lot of work needs to be done here, and some of this code will
eventually move to C most likely, but this is a good way to better
exercise our backend.
Type inference - at the very least _forward_ inference, is the most
needed change here. While one could do this in the compiler
frontend, doing so in sysir/asm is not so much of an issue. "Inference"
here means inserting "bind" instructions when there is only a single
type that will work correctly.
In the edge-trigger mode before this change, if a socket
receives 2 connections before one can be handled, then only a single
connection is handle and 1 connection will never be handled in some
cases. Reverting to level-trigger mode makes this impossible.
