From: Chris Koeritz Date: Sun, 31 Oct 2021 23:15:56 +0000 (-0400) Subject: tectonic tribulations edition: host preparation X-Git-Tag: 2.140.134~4^2~17 X-Git-Url: https://feistymeow.org/gitweb/?a=commitdiff_plain;h=3974d01da6ece6956c0bff67e800d1a02d9faa80;p=feisty_meow.git tectonic tribulations edition: host preparation needed for a bit; just automates a lot of separate install instructions. planning to support windows with apt-cyg and mac with brew, but those steps are kinda hosed still. is_feisty_up lets a caller know if the system is initialized yet or not, which was needed in prep_feisty_host. functions have a couple changes, esp. a better whichable that now returns an error code instead of just not echoing text. --- diff --git a/readme.txt b/readme.txt index e77c89ab..4b52f9ba 100644 --- a/readme.txt +++ b/readme.txt @@ -15,6 +15,8 @@ If you have stored it elsewhere, then please adapt the commands accordingly.
