Watching a command with pipe

[Trustin Lee]

Hi!

I'm trying to use hwatch for the following command:

ls | wc -l

I tried the following but none worked so far:

• hwatch -- 'ls | wc -l'
• hwatch -- ls '|' wc -l

Wow!

I also confirmed it.
Apparently, it seems to be a bug caused by the change in Version 0.3.5.
Thank you!!

The cause is that the processing at the time of command execution was changed in order to specify the -s option.

hwatch/src/exec.rs

Lines 58 to 90 in 4a94258

 // split self.shell_command 
 let shell_commands = 
     shell_words::split(&self.shell_command).expect("shell command parse error."); 
  
 // set shell_command args, to exec_cmd_args. 
 exec_cmd = shell_commands[0].to_string(); 
 if shell_commands.len() >= 2 { 
     let length = shell_commands.len(); 
     let shell_command_args = shell_commands[1..length].to_vec(); 
  
     // shell_command_args to exec_cmd_args 
     for shell_command_arg in shell_command_args { 
         let exec_cmd_arg: String; 
         if shell_command_arg.contains("{COMMAND}") { 
             exec_cmd_arg = str::replace( 
                 &shell_command_arg, 
                 crate::SHELL_COMMAND_EXECCMD, 
                 &command_str, 
             ); 
             is_shellcmd_template = true; 
         } else { 
             exec_cmd_arg = shell_command_arg; 
         } 
  
         // push exec_cmd_arg to exec_cmd_args 
         exec_cmd_args.push(exec_cmd_arg); 
     } 
 } 
  
 // add exec command.. 
 if !is_shellcmd_template { 
     exec_cmd_args.push(command_str.clone()); 
 } 

We will fix it early.

NOTE:

The cause was that it was quoted by using shell_words :: join.

hwatch/src/exec.rs

Line 54 in 4a94258

 let command_str = shell_words::join(self.command.clone());

Thanks a lot for a very quick fix, @blacknon! 🙇 Just installed and confirmed the fix works.
