add substitution variable for line_number

[bigla]

Goal

Open the source of a derived file when debugging derived files at exact same line. Because this makes this great tool even more flexible.

Explanation

I have some project generating derived files from source files with a different extension, without changing the file line numbers.

I'd love to be able to open the source file in an external editor passing the exact same line number where I am currently at (or where warnings and errors are indicating problems) using something along the lines of:
eclipse -name Eclipse --launcher.openFile ${easyshell:container_name}${easyshell:file_separator}${easyshell:resource_basename}.cu:${easyshell:resource_line_number}

Any occuring line breaks in above command not intended!

Example files:
derived file: myDerivedfile.cudato.cpp
source file: myDerivedfile.cu

Suggestion for a substitution variable name

${easyshell:resource_line_number}

For now I am using a bash script with the Eclipse built in "External Tools Configurations..."
(of course running without rebuilding - contact me if full configuration shall be posted here.)
configured External Tools arguments: ${selected_file} ${selected_text}

This is of course only for my special case described above. And no error handling, nor input sanitization is done.
WARNING: This assumes the first found line containing selected content is the right one.

set -x

selected_file=$1
selected_text=$2

echo "$selected_file"
echo "$selected_text"

selected_file_no_ext=${selected_file%.cudato.cpp}

echo "$selected_file_no_ext"

line_number="$(grep -nF "$selected_text" "$selected_file" | head -n 1 | cut -d : -f 1)"

echo "$line_number"


eclipse -name Eclipse --launcher.openFile "$selected_file_no_ext".cu:$line_number

Workaround can be configured similarly to this Stackoverflow page answer.

FYI:
Sounds like Eclipse forgot about this Idea.
