Swiftbar 2.0.0

Hi, i want to pass single quote as parameter to bash program (with terminal=false)

In general, I want to make sure that I escape input from (paste/clipbard)board.

I was unable to pass single qoute, (only in some cases i was able to pass double quote)

Here is what i try:

I have simple test PHP script to determine and logs parameters

#!/opt/homebrew/bin/php
<?php

file_put_contents(realpath(__DIR__) . '/.logs.txt', print_r($argv, true) . PHP_EOL , FILE_APPEND | LOCK_EX);

and I have this swiftbar script:

Escaping
---
1. without param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php'
---
2. text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1=text
3. text param single quoted | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1='text text'
4. text param double quoted | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text text"
---
5. single quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1=text's
6. single quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text's"
7. single quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text\'s"
8. single quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text\\'s"
---
9. double quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1=text"s
10. double quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text"s"
11. double quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1='text"s'
12. double quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1=\'text\"s\'

And results

1. without param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php'

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
)

✅ This is OK - no parameters given, no parameters logged

2. text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1=text

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text
)

✅ This is OK - one parameter is given, same parameter is recieved and logged

3. text param single quoted | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1='text text'

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text text
)

✅ This is OK - one parameter is given, same parameter is recieved and logged

4. text param double quoted | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text text"

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text text
)

✅ This is OK - one parameter is given, same parameter is recieved and logged

5. single quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1=text's

Console.app output:

default	19:17:47.213953+0200	SwiftBar	Executing script in background... 
/Users/matej/Projects/Others/BitBarPlugins/.write.php
error	19:17:47.282829+0200	SwiftBar	Failed to execute script in background
/bin/bash: -c: line 0: unexpected EOF while looking for matching `''
/bin/bash: -c: line 1: syntax error: unexpected end of file

❌🤔 my script wasn't callet at all (but this may be excepted behaviour, but see 9. with double quotes it works)

6. single quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text's"

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text
)

Console.app output is without parameters, so I can't determine wat was actually called

default	19:18:37.328480+0200	SwiftBar	Executing script in background... 
/Users/matej/Projects/Others/BitBarPlugins/.write.php

❌ This not OK - only "text" was passed to the program, even when param1 was escaped/surrounded by double quotes

7. single quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text\'s"

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text\
)

❌ This not OK - as in previews example, parameter was cut just before single quote

8. single quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text\\'s"

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text\\
)

❌ This not OK - as in previews example, parameter was cut just before single quote

9. double quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1=text"s

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text"s
)

✅ This is OK

10. double quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1="text"s"

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text
)

✅ This is OK - i would expect such a behaviour

11. double quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1='text"s'

Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text
)

❌ This not OK - only "text" was passed to the program, even when param1 was escaped/surrounded by single quotes

12. double quote in text param | terminal=false bash='/Users/matej/Projects/Others/BitBarPlugins/.write.php' param1=\'text\"s\'

❌🤔 my script wasn't callet at all

is there any way to escape and pass single quote in bash program parameter? Or maybe see some logs what swiftbar parse and call when i click to row?

1. 
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
)

2.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text
)

3.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text text
)

4.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text text
)

5.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text's
)

6.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text's
)

7.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text\'s
)

8.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text\\'s
)

9.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text"s
)

10.
- no valid syntax

11.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => text"s
)

12.
Array
(
    [0] => /Users/matej/Projects/Others/BitBarPlugins/.write.php
    [1] => \'text\"s\'
)
