Enhanced onEdit(e) using Google Apps Script

Gists

onEdit(e) which is used for the Edit event on Spreadsheet has the old value as e.oldValue. The specifications for this are as follows.

  1. When an user edited a single “A1” cell, e of onEdit(e) shows hoge for e.oldValue and fuga for e.value.
  2. When an user edited the “A1:A2” multiple cells, e.oldValue and e.value of onEdit(e) are not shown anything.
  3. When an user copied and pasted from other cell, e.oldValue and e.value of onEdit(e) are not shown anything.

This sample script was created to retrieve both the edited values and the old values for the range of edited cells. This is the modified e.oldValue.

Uploading CSV File as Spreadsheet and Modifying Permissions using Golang

Gists

This sample script is for uploading CSV file as Spreadsheet and modifying permissions using Golang.

I think that the detail information of google-api-go-client is a bit little. The sample scripts are so little. It retrieves most information from only godoc and GitHub. So I publish such sample scripts here. If this is useful for you, I’m glad.

Important points :

  1. Give mimeType of file that it wants to upload to options of Media(r io.Reader, options ...googleapi.MediaOption).
  2. In order to give options, use googleapi.ContentType().
  3. Give mimeType of file that it wants to convert, when it uploads it to Google Drive, to file of Create(file *File).
  4. In order to give file, use &drive.File{}.
  5. For installing permissions, use &drive.Permission{}. Each parameter is the same to them for Python.

This sample script uses Quickstart. So in order to use this sample script, at first, please do Step 1 and Step 2 of the Quickstart.

Selecting Files in Google Drive using Select Box for Google Apps Script

Gists

This is a sample script for selecting files in Google Drive using HTML select box for Google Apps Script.

Feature

Feature of this sample.

  • It is a simple and space saving.
  • When the folder is selected, the files in the folder are shown.
  • When the file is selected, the ID of file is retrieved. Users can use this ID at GAS.
  • When a folder is opened, all files in the folder are cached. By this, the second access of the folder is faster.
  • It doesn’t retrieve all files in Google Drive at once, so the read of files from Google Drive becomes the minimum necessary.

I will use this for applications that users need to select files on Google Drive.

Updated ggsrun to v131

ggsrun was updated to v.1.3.1

  1. Recently, when scripts on local PC is uploaded to Google Drive as a new project, the time to create on Google became a bit long. (I think that this is due to Google Update.) Under this situation, when the script is uploaded, the timeout error occurs while the new project is created using the script. So the time until timeout of fetch was modified from 10 seconds to 30 seconds. By this, when the script is uploaded, no error occurs and the information of the created project is shown.
    • You can create a new project on Google Drive using scripts on local PC. The sample command is ggsrun u -f sample.gs1,sample2.gs,sample3.html -pn newprojectname

You can check this and download ggsrun at https://github.com/tanaikech/ggsrun.

Uploading Image Files to Slack Using Incoming Webhooks by Google Apps Script

Retrieving Files with Filename Included Special Characters using Google Apps Script

Gists

This sample script is for retrieving files with filename included special characters using Google Apps Script. The files are used on Google Drive.

The files with filename of special characters cannot be retrieved using DriveApp.getFilesByName(). This workaround solved this.

As a query parameter, name contains 'filename with special characters' is used. This contains is very important. name='filename with special characters' cannot retrieve such files. Today, it was found that name contains 'filename with special characters' is the workaround. I have been looking for this workaround for a while. Finally, I found this today. By using this method, filename included umlauts can be also retrieved.

Removing Duplicated Values in Array using CoffeeScript

Gists

This sample script is for removing duplicated values in array using CoffeeScript.

ar = ["a", "b", "c", "a", "c"]
res = ar.filter (e, i, s) -> s.indexOf(e) is i
console.log res

>>> [ 'a', 'b', 'c' ]

The result which was compiled by CoffeeScript is as follows.

var ar, res;
ar = ["a", "b", "c", "a", "c"];
res = ar.filter(function(e, i, s) {
  return s.indexOf(e) === i;
});
console.log(res);
