[CDT 9.2] Run/Debug Configurations are HORROR ... [message #1782898]

Where is the fucking manual for arguments specification ???
Else what is the logic ???

Use Case :

Here is submitted to the argument line (Debug configuations -> Arguments -> Program arguments) :

${project_loc_loc}${system_property:file.separator}intern${system_property:file.separator}

What is expected on Windows :

<project effective path>\intern\

What is actually obtained :

<project effective path>intern

Ok ! anti-slash is the special character. Well, I adapt :

${project_loc}\${system_property:file.separator}intern\${system_property:file.separator}

Obtained :

<project effective path>\\\\intern\\\\

My god ...

As a result :
The argument line interpreter acts like this :
- if there is a single anti-slash, then delete it
- if there are two consecutive anti-slashes, then double them.

So, it never returns a single anti-slash.

Don't mind ... trying with single quote enclosure :

${project_loc}'${system_property:file.separator}intern${system_property:file.separator}'

Obtained:

<project effective path>'\\intern\\'

Great ... not only anti-slashes are doubled inside single quotes but single quotes are preserved ...

True to its principle: follow no functional logic...

trying with double quote enclosure :

${project_loc}"${system_property:file.separator}intern${system_property:file.separator}"

Obtained ... A nightmare :

<project effective path>\\intern\"

The opening double quote is removed but the closing one, the first anti-slash is double but not the second one while it is in the same condition as the first one.

Can't be understood.

The software designer was drunk...

Is there a documentation about the argument line syntax ?
Else, how to make this right ?

I fed up.

Thanks a lot.

The one who has the solution must be rewarded.

You post doesn't explain the basic task you are trying to accomplish, but you seem to be trying to pass the path to the intern directory in your project as an argument to the program you are running. You might want to look into using the resource_loc variable. Any file or directory in your workspace is considered a resource of the project. The resource_loc variable allows you to pass the absolute path of one of these resources as a program argument. Eclipse should perform the correct platform formatting so you don't need to construct it using things like file.separator. You specify the resource you want to resolve as an argument in the resource:loc definition. To pass the \intern\ directory from the root directory of your project, you specify {resource_loc:project_name/intern.

There is documentation on the different resource/location variables in the Workspace User Guide->Concepts->Ant & External tools->External tools.

Thanks a lot, David.

I'm discovering :
What I want to do is not part of CDT but Eclipse workbench: to extend a variable path.
It is advisable to do this like documentation recommends.
This documentation is not there the user should expert to be.
And the contextual documentation itself is quiet about the subject. What a pity.

Thanks again and best regards, David.
