# Purpose {{{
|
|||
|
|
# This script will try to get last version of alacritty .deb file
|
|||
|
|
# https://github.com/gardouille/alacritty-debian
|
|||
|
|
# 1. Get current version from APT repo (by default).
|
|||
|
|
# 1.b Or use version from manually installed package (with --file option).
|
|||
|
|
# 2. Get latest version from github repository.
|
|||
|
|
# 3. Compare current and new versions.
|
|||
|
|
# 4. Download the .deb file for this new version.
|
|||
|
|
# 5. Create a temp file (to monitor) if an upgrade is available.

# How-to use {{{
|
|||
|
|
## 1. Needs releasetags script, in the same directory
|
|||
|
|
## cf. https://git.ipr.univ-rennes1.fr/cellinfo/scripts/src/master/github/releasetags
|
|||
|
|
# wget https://git.ipr.univ-rennes1.fr/cellinfo/scripts/raw/master/github/releasetags
|
|||
|
|
## 2. Create a cron job, eg :
|
|||
|
|
#00 20 * * * root /opt/repos/ipr.scripts/github/check.alacritty.update
|
|||
|
|
## 2-1 Create a cron job to compare the version of manually installed package
|
|||
|
|
#00 20 * * * root /opt/repos/ipr.scripts/github/check.alacritty.update --file
|
|||
|
|
## 3. Monitor the temp file : /tmp/.github.alacritty.upgrade
