Check JavaScript License Script

TODO: collapasable, copyable, download, etc

Can you write me a bash script to recursively look at all the .js files under ./src and check that the first few lines have a license block that matches a text file that I give as input?Certainly! To create a Bash script that recursively checks if the first few lines of all .js files under ./src directory match a given license block from a text file, you need to follow these steps:

Read the License Text: Read the contents of the license text file provided as input.
Find JavaScript Files: Recursively find all .js files under the ./src directory.
Compare License Block: Extract the first few lines from each JavaScript file and compare them with the license text.
Output the Results: Print the result for each file, indicating whether it matches the license block or not.

Here's a Bash script that does this:

#!/bin/bash

# Check if a file path for the license text is provided
if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <path-to-license-file>"
    exit 1
fi

license_file="$1"

# Read the license content
license_content=$(cat "$license_file")

# Function to check the license in a JS file
check_license() {
    local file="$1"
    local file_header=$(head -n $(wc -l < "$license_file") "$file") # Adjust the number of lines as needed

    if [[ "$file_header" == "$license_content" ]]; then
        echo "License matches in $file"
    else
        echo "License does NOT match in $file"
    fi
}

# Export the function so it's available to the subshell spawned by find
export -f check_license

# Recursively find .js files in ./src and check the license
find ./src -type f -name '*.js' -exec bash -c 'check_license "$0"' {} \;

Save this script in a file, for example, check_license.sh, and make it executable with chmod +x check_license.sh. Then, run it with the path to your license file as an argument:

./check_license.sh path/to/license.txt

This script assumes that the number of lines in the license block is the same as in the provided license text file. Adjust the head -n command as needed if your license block has a different number of lines.I get errors like ./src/routes/v2/infer/create_session/+server.js: line 1: : No such file or directory head: illegal line count -- ./src/routes/v2/infer/create_session/+server.jsThe error you're encountering suggests that the script is trying to treat the JavaScript files as input to the head command, rather than as filenames. This can happen due to the way the check_license function is being invoked in the find command. Let's modify the script to avoid this issue.

Here's a revised version of the script:

#!/bin/bash

# Check if a file path for the license text is provided
if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <path-to-license-file>"
    exit 1
fi

license_file="$1"

# Read the license content
license_content=$(cat "$license_file")

# Function to check the license in a JS file
check_license() {
    local file="$1"
    local file_header=$(head -n $(wc -l < "$license_file") "$file") # Adjust the number of lines as needed

    if [[ "$file_header" == "$license_content" ]]; then
        echo "License matches in $file"
    else
        echo "License does NOT match in $file"
    fi
}

# Recursively find .js files in ./src and check the license
export -f check_license
find ./src -type f -name '*.js' -exec bash -c 'check_license "$0"' {} \;

In this revised script, the check_license function is exported so that it's available in the subshell created by find. Also, the arguments for check_license are passed correctly.

Run the script in the same way as before:

./check_license.sh path/to/license.txt

Make sure that the license file path you provide is correct and that the script has execute permissions. If you still encounter issues, please share the specific error messages for further troubleshooting.It is still a problem. Here is the last part of the output License matches in ./src/routes/api/metrics/autocomplete/+server.js ./src/routes/api/metrics/query/+server.js: line 1: : No such file or directory head: illegal line count -- ./src/routes/api/metrics/query/+server.js License matches in ./src/routes/api/metrics/query/+server.js ./src/routes/api/metrics/+server.js: line 1: : No such file or directory head: illegal line count -- ./src/routes/api/metrics/+server.js License matches in ./src/routes/api/metrics/+server.js ./src/routes/api/db_/+server.js: line 1: : No such file or directory head: illegal line count -- ./src/routes/api/db_/+server.js License matches in ./src/routes/api/db_/+server.js ./src/routes/api/inference/+server.js: line 1: : No such file or directory head: illegal line count -- ./src/routes/api/inference/+server.js License matches in ./src/routes/api/inference/+server.jsThe issue seems to be related to the handling of file paths and the invocation of the check_license function within the find command. The find command spawns a new shell for each file it processes, and it appears that the environment (including the exported function and its variables) is not being correctly passed to these subshells.

Let's try a different approach by embedding the license checking logic directly within the -exec clause of the find command. This will avoid potential issues with exporting functions and variable scopes:

#!/bin/bash

# Check if a file path for the license text is provided
if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <path-to-license-file>"
    exit 1
fi

license_file="$1"

# Read the license content
license_content=$(cat "$license_file")
license_line_count=$(wc -l < "$license_file")

# Recursively find .js files in ./src and check the license
find ./src -type f -name '*.js' -exec bash -c ' 
    file="$1"
    license_content="'"$license_content"'"
    license_line_count='"$license_line_count"'

    file_header=$(head -n $license_line_count "$file")

    if [[ "$file_header" == "$license_content" ]]; then
        echo "License matches in $file"
    else
        echo "License does NOT match in $file"
    fi
' bash {} \;

This script passes the license content and the line count directly into the -exec command, avoiding the need for an exported function. It should handle the file paths correctly.

Run the script as before:

./check_license.sh path/to/license.txt

This approach should resolve the issues you were facing. If any errors still occur, it might be related to specific characteristics of the files being processed or the environment. Let me know if further adjustments are needed!That is worse. Let's go back to ```#!/bin/bash

Check if a file path for the license text is provided

if [ "$#" -ne 1 ]; then echo "Usage: $0 " exit 1 fi

license_file="$1"

Read the license content

license_content=$(cat "$license_file")

Function to check the license in a JS file

check_license() { local file="$1" local file_header=$(head -n $(wc -l < "$license_file") "$file") # Adjust the number of lines as needed

if [[ "$file_header" == "$license_content" ]]; then
    echo "License matches in $file"
else
    echo "License does NOT match in $file"
fi

}

Recursively find .js files in ./src and check the license

export -f check_license find ./src -type f -name '*.js' -exec bash -c 'check_license "$0"' {} ;


I think maybe head isn't getting the right variables. Can you add echo to debug on all variables in the script. I will run it so that you can see the output and troubleshoot the errors. Certainly! Adding debug statements can help us understand where the issue might be occurring. We'll add `echo` statements to print out the relevant variables at different points in the script. This will help identify if the variables are being passed correctly and if they hold the expected values.

Here's the modified script with debug statements:

```bash
#!/bin/bash

# Check if a file path for the license text is provided
if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <path-to-license-file>"
    exit 1
fi

license_file="$1"
echo "License file: $license_file"

# Read the license content
license_content=$(cat "$license_file")
echo "License content:"
echo "$license_content"

license_line_count=$(wc -l < "$license_file")
echo "License line count: $license_line_count"

# Function to check the license in a JS file
check_license() {
    local file="$1"
    echo "Checking file: $file"

    local file_header=$(head -n $license_line_count "$file")
    echo "File header:"
    echo "$file_header"

    if [[ "$file_header" == "$license_content" ]]; then
        echo "License matches in $file"
    else
        echo "License does NOT match in $file"
    fi
}

# Recursively find .js files in ./src and check the license
export -f check_license
export license_content
export license_line_count
find ./src -type f -name '*.js' -exec bash -c 'check_license "$0"' {} \;

This script will print out the path of the license file, the content of the license file, the number of lines in the license file, and similar information for each JavaScript file it checks. Run the script and share the output, and we can analyze it to identify where the problem lies.bash find_license.sh license.txt License file: license.txt License content: /*

It successfully identifies files that match the license text and those that don't. The echo debug statements confirm that the license content, the file being checked, and the file header are all being read and compared as expected.

From the output:

The script correctly identifies files that contain the license at the beginning (e.g., ./src/stores/tool_store.js).
It also correctly identifies files that do not have the license at the beginning (e.g., ./src/server/user_hash.js).

The instances where the script reports "License does NOT match" are accurate based on the comparison between the license text and the file headers. These files either start with code directly or have a different header.

If your intention is to ensure that all .js files in the ./src directory start with this specific license header, then the script is working as intended. For files where the license does not match, you'll need to manually check if the license block is present elsewhere in the file or is missing entirely.

If there are specific conditions or variations in how the license text is included in the files (like additional spaces, line breaks, or comments), those need to be taken into account for a more nuanced comparison. However, based on the current requirement and the output you've provided, the script behaves as expected.
