[gull] Truc et astuces: swift stat

[felix]

Pour ceux qui utilisent swift (restic) et qui seraient d'accord que ça:
                        Account: AUTH_░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░
                     Containers: 2
                        Objects: 26627
                          Bytes: 457482129594
Containers in policy "policy-0": 2
   Objects in policy "policy-0": 26627
     Bytes in policy "policy-0": 457482129594
               Meta Quota-Bytes: 1000000000000
                   Content-Type: text/plain; charset=utf-8
                    X-Timestamp: 1686835224.52240
                  Accept-Ranges: bytes
    X-Account-Project-Domain-Id: _unknown
                           Vary: Accept
                     X-Trans-Id: tx░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░
         X-Openstack-Request-Id: tx░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░
      Strict-Transport-Security: max-age=63072000

c'est moins joli que ça:
▕⠀⠀▏ 45.75%                 Account: AUTH_░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░
▕⠀⠀▏                     Containers: 2
▕⠀⠀▏                        Objects: 26627
▕⠀⠀▏                          Bytes: 457482129594
▕⠀⠀▏Containers in policy "policy-0": 2
▕⠀⠀▏   Objects in policy "policy-0": 26627
▕⠀⠀▏     Bytes in policy "policy-0": 457482129594
▕⠀⠀▏               Meta Quota-Bytes: 1000000000000
▕▂▂▏                   Content-Type: text/plain; charset=utf-8
▕██▏                    X-Timestamp: 1686835224.52240
▕██▏                  Accept-Ranges: bytes
▕██▏    X-Account-Project-Domain-Id: _unknown
▕██▏                           Vary: Accept
▕██▏                     X-Trans-Id: tx░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░
▕██▏         X-Openstack-Request-Id: tx░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░
▕██▏      Strict-Transport-Security: max-age=63072000

Voici comment j'ajoute une barre de remplissage verticale et
modifie la première ligne pour ajouter l'état en poucents:

#!/bin/bash

source path/to/swiftEnvironment

swiftStat="$(swift stat)"
mapfile -t lines <<<"${swiftStat}"

policyBytes=${swiftStat#*Bytes in policy*: }
policyBytes=${policyBytes%%$'\n'*}

quotaBytes=${swiftStat#*Quota-Bytes: }
quotaBytes=${quotaBytes%%$'\n'*}

barHeight=$(( 8*${#lines[@]} * policyBytes / quotaBytes ))

prct=00$(( 100000 * policyBytes / quotaBytes ))
printf -v lines[0] '%6.2f%%%s' ${prct::-3}.${prct: -3} "${lines[0]:7}"

blockFull=$(( barHeight / 8 ))
emptyBlocks=$(( ( ${#lines[@]} * 8 - barHeight ) / 8 ))
lastBlock=$(( barHeight % 8 ? barHeight % 8 : 8)) 

for i in ${!lines[@]};do
    printf '\U2595%b%b\U258F%s\n' \\U2$(( i < emptyBlocks ? 800 :
    i ==  ${#lines[@]} - blockFull - 1 ? 580+lastBlock : 588 )){,} "${lines[i]}"
done
