[gull] A propos de shellcheck was Re: [noreply at letsencrypt.org:.

[Félix Hauri]

Le premier: https://f-hauri.ch/vrac/reshellcheck.sh
partait du constat que la sortie par défaut de shellcheck est lourde!
J'ai donc cherché à ``systématiser'' et réduire la sortie:

  $ ./reshellcheck.sh showColor.sh
  NOTE 4x
     1x SC2015:  Note that A && B || C is not if-then-else. C may run when A is true.
         7 (1):         (( ( pointer - 1 ) % colsperline )) && printf ' ' || { 
     3x SC2086:  Double quote to prevent globbing and word splitting.
        13 (3):            "$color" 0x${color:1:2} 0x${color:3:2} 0x${color:5:2} '' '' ''
  WARNING 1x
     1x SC2183:  This format string has 2 variables, but is passed 1 argument.
         8 (1):             printf -v lines '%*s' $((pointer>1?8:4))
  Total: 5 remarks (4 note, 1 warning).

(A noter que j'utilise la couleur pour situer l'empacement normalement
 indiqué par des lignes (redondantes) commencant par "^".)

En ordonnant les ``notes'' avant les ``warnings'', suivit des ``errors''.
A comparer avec:

  $ shellcheck showColor.sh

  In showColor.sh line 7:
        (( ( pointer - 1 ) % colsperline )) && printf ' ' || { 
                                            ^-- SC2015 (info): Note that A && B || C is not if-then-else. C may run when A is true.


  In showColor.sh line 8:
            printf -v lines '%*s' $((pointer>1?8:4))
                            ^---^ SC2183 (warning): This format string has 2 variables, but is passed 1 argument.


  In showColor.sh line 13:
                 "$color" 0x${color:1:2} 0x${color:3:2} 0x${color:5:2} '' '' ''
                            ^----------^ SC2086 (info): Double quote to prevent globbing and word splitting.
                                           ^----------^ SC2086 (info): Double quote to prevent globbing and word splitting.
                                                          ^----------^ SC2086 (info): Double quote to prevent globbing and word splitting.

  Did you mean: 
                 "$color" 0x"${color:1:2}" 0x"${color:3:2}" 0x"${color:5:2}" '' '' ''

Quant au second: https://f-hauri.ch/vrac/parShellCheck.sh

Il parallelise shellcheck et trie les réponses et effecue une stat
d'ensemble:

$ ./parShellCheck.sh <path>

ou

$ ./parShellCheck.sh <file> <file> 

Exemple:

  $ ./parShellCheck.sh showColor.sh coprocDate.source.sh
  Found: 2 files to check with max 4 instances.
