vscode-extensions: script to generate Nix for "latest" version of all installed vscode extensions Added better practices to update_exts script. Use `jq` instead of `grep` for more reliable JSON querying. Check for 404 when requesting package.json information to avoid mangled output. Added proper failure points for missing vscode package, unknown version, and if the code executable couldn't be found. Switched to using a `nix-shell` shebang for even better reliability and use the `sh` shell to be that little bit more generic. Script is still clunky and sequential, anything more and I'd need to write a proper program to do this and that's getting a bit silly? But people that have a dozen or so extensions might be in for a long wait. Be explicit about using bash Improve the use of jq to remove unnecessary use of tr. Hat-tip coretemp. Add some comments, finally. Remove the `fetch` function. Change the `get_ver` function to more accurately demonstrate what it is trying to do, as well as add in some better error handling for non-200 http responses. I couldn't make the bash `${param/search/replacement}` work for chopping up the response in the `get_ver` function, hence the use of `sed`. Hopefully it all makes a bit more sense now. Remove github requests. VSIXPackage is just a zip format in disguise so use a tmpdir and unpackage the package.json file for the file in question so we can get the precise version that we're interested in without additional redundant calls to github that may not provide the right answer anyway. Add trap to try to clean up the temp folders and clean up as we go. I can't use 'fetchurl' or even 'nix-prefetch-url' because for the former we don't yet know the hash that we're after and for the latter there isn't a way to tie the predownloaded file into the next part of the workflow. Prevent an unnecessary file from being extracted. Change the unzip command to read the file we're after to stdout so we can use jq on it directly instead of creating a file, reading it, then deleting it. Courtesy of worldofpeace, remove the dependency on coreutils and use the provided nix-hash function to generate the required hash. Fix up a comment Remove use of 'awk' and clean up individual Nix printing with cat to EOF expression.
