Creating and Applying 9front Patches

Creating

To create a patch we first pull 9front’s hg repo and bind our files into place:

sysupdate

bind -a /dist/plan9front /

cd /

In this example we’re making a patch for rio, any combination of folders should work:

bind $home/src/rio /sys/src/cmd/rio

To get the latest commit:

hg log | sed 5q

A first log output example might be:

changeset:   6705:eecec6d3b341
user:        cinap_lenrek@felloff.net
date:        Mon Sep 03 20:54:26 2018 +0200
summary:     vt: fix plumbsel(), snarfsel()

The commit hash we’re looking for is eecec6d3b341 and we can use it as follows to make the diff file:

hg diff -r eecec6d3b341 /sys/src/cmd/rio/wind.c > $home/mypatch.diff

Applying

In the same way we pull and bind our files into place:

sysupdate

bind -a /dist/plan9front /

cd /

For individual files you could use ape/patch if desired, but for most 9front patches you should use hg:

hg import --no-commit -f $home/mypatch.diff

The patch is now applied!

If you wish to trash the changes from the patch, use:

hg revert
