Updated ggsrun to v134

ggsrun was updated to v.1.3.4 v1.3.4 (January 2, 2018) Added new option for downloading ‘bound-scripts’ of Google Sheets, Docs, or Forms file. When the bound-scripts are downloaded, the project name cannot be retrieved because Drive API cannot be used for the bound-scripts. So when the bound-scripts are downloaded, the project ID had been used previously. Such filename is not easily to be seen. By this additional option, users can give the filename when it downloads the bound-scripts.

Create New Project with Original Manifests

It was found that you can also create new project with your original Manifests using ggsrun. By using this, for example, when you created new project, the project can have libraries, Advanced Google Services and so on at the initial stage. I think that this can be used as a template for Project. $ ggsrun u -pn [Project name] -f appsscript.json https://github.com/tanaikech/ggsrun/blob/master/help/README.md#ModifyManifests **You can check this and download ggsrun at https://github.

By using this, you can edit the manifests and update it from your local PC.

Updated ggsrun to v132

ggsrun was updated to v.1.3.2 v1.3.2 (October 20, 2017) Updated ggsrun's Install manual (README.md). Since I thought that the manual became too complicated, I separated it to the simple version and the detail version. And also , recently, since Google's specification was updated, about how to deploy API executable and enable APIs for ggsrun's Install manual were updated. From this version, scripts in a project can be rearranged.

Updated go-rearrange and gorearrange to v102

go-rearrange and gorearrange were updated to v.1.0.2 From this version, data included multi-bytes characters can be used. At Linux, it works fine. At Windows DOS, rearranging and selecting data can be done. But the displayed data is shifted. Although this may be a bug of termbox-go, I don't know the reason. I'm sorry. On the other hand, data with only single-byte characters works fine. About MAC, I don't have it. If someone can confirm and tell me it, I'm glad.

Updated go-rearrange and gorearrange to v101

go-rearrange and gorearrange were updated to v.1.0.1 As one of outputs, indexmode (bool) was added. If this is true, the rearranged result is output as the change of index for the source data. For example, if the source data and rearranged data are ["a", "b", "c"] and ["c", "b", "a"], respectively. The output will become [2, 1, 0]. By this, the specification for creating applications will expand. **The detail information and how to get this are https://github.

Updated ggsrun to v131

ggsrun was updated to v.1.3.1 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.

So the time until timeout of fetch was modified from 10 seconds to 30 seconds.

Updated ggsrun to v130

ggsrun was updated to v.1.3.0 From this version, container-bound scripts can be downloaded.

Updated ggsrun to v122

ggsrun was updated to v.1.2.2 For Google Docs (spreadsheet, document, slide and drawing), since I noticed that the revision files would not be able to be retrieved using Drive API v3, I modified this using new workaround. The new workaround is to use Drive API v2. drive.revisions.get of Drive API v2 can retrieve not only the revision list, but also the export links. I thought of the use of the export links.

CLI Tool - gislack

Overview This is a CLI tool to submit files to both Gist and Slack. Description When I discuss about developing scripts, I often use Slack. When I submitted a script to Slack, I had saved the script to Gist as a backup. I had done manually this on my browser. Namely, I wanted to be saving the revision of script while I'm discussing about the script at Slack. Recently, I wished this process had been able to be automatically run.

Go Library - getcode

Slice Created by Split at Golang

When a string without no strings is split by strings.Split(), the created slice is the same to the slice created by make(). The length of the slice doesn't become zero. Sample script : package main import ( "fmt" "strings" ) func main() { sample1a := strings.Split("", " ") fmt.Printf("%v, %v, '%v', %v, %+q\n", sample1a, len(sample1a), sample1a[0], len(sample1a[0]), sample1a[0]) sample1b := make([]string, 1) fmt.Printf("%v, %v, '%v', %v, %+q\n", sample1b, len(sample1b), sample1b[0], len(sample1b[0]), sample1b[0]) var sample2a []string fmt.

This sample is for replacing JSON key by golang. package main import ( "encoding/json" "fmt" ) func main() { json1 := `{"key1": "value1"}` obj := map[string]interface{}{} json.Unmarshal([]byte(json1), &obj) fmt.Println(obj) // <-- map[key1:value1] obj["key2"] = obj["key1"] delete(obj, "key1") fmt.Println(obj) // <-- map[key2:value1] }

Benchmark: Splitting Command-Line Arguments by Golang

This sample script is for splitting command-line arguments by golang. There are 2 types. One is the regular expression is used. Another is that Split() and TrimSpace() are used. Here, each process speed was compared. Script : package main import ( "regexp" "strings" "testing" ) func BenchmarkB1(b *testing.B) { str := "test1.txt, test2.txt" b.ResetTimer() for i := 0; i < b.N; i++ { ar := regexp.MustCompile(`\s*,\s*`).Split(str, -1) var result []string for _, x := range ar { result = append(result, x) // --> 'test.

Decoding JSON by Golang

Decoding JSON by Golang func main() { data := `{ "A_key1": { "B_key1": { "C_key": "value" } }, "A_key2": { "B_key2": { "C_key": "value" } }, "A_key3": { "B_key3": { "C_key": "value" } }, "A_key4": { "B_key4": { "C_key": "value" } }, "A_key5": { "B_key5": { "C_key": "value" } } }` var p interface{} json.NewDecoder(strings.NewReader(data)).Decode(&p) fmt.Println(p) } Go Playground

Updated: CLI Tool - goris

goris is a CLI tool to search for images with Google Reverse Image Search. Today, it was updated to v1.0.1. Please check it out. https://github.com/tanaikech/goris When number of retrieved URLs is smaller than number of default output, an error had occurred. This was fixed.

Dynamical Nested JSON Objects by Golang

This sample script dynamically creates nested JSON objects. Script obj := map[string]interface{}{} for i := 1; i <= 5; i++ { value := map[string]interface{}{ fmt.Sprintf("B_key%d", i): map[string]interface{}{ "C_key": "value", }, } obj[fmt.Sprintf("A_key%d", i)] = value } Result { "A_key1": { "B_key1": { "C_key": "value" } }, "A_key2": { "B_key2": { "C_key": "value" } }, "A_key3": { "B_key3": { "C_key": "value" } }, "A_key4": { "B_key4": { "C_key": "value" } }, "A_key5": { "B_key5": { "C_key": "value" } } }

Updated: CLI Tool - gogauth

gogauth is a CLI tool to easily retrieve access token for using APIs on Google. I thought that if the access token can easily retrieve, it may be useful for users who can use various convenience Google APIs. So I created this. Also this can be used for testing sample script like the demo. If this will be helpful for you, I'm glad. Today, it was updated to v2.0.1. Please check it out.

Updated ggsrun to v110

Updated ggsrun to v.1.1.0 Added a command for updating existing project on Google Drive. One of scripts in the project can be also updated. https://github.com/tanaikech/ggsrun

CLI Tool - goris

Overview This is a CLI tool to search for images with Google Reverse Image Search. Motivation Because I had wanted to search for images with an image URL and file on my terminal, I created this. This can download images from searched image URLs. **The detail information and how to get this are https://github.

CLI Tool - ggsrun

Overview This is a CLI tool to execute Google Apps Script (GAS) on a terminal. Motivation Will you want to develop GAS using CoffeeScript on your local PC? Generally, when we develop GAS, we have to login to Google using own browser and develop it using Javascript on the Script Editor. Recently, I have wanted to have more convenient local-environment for developing GAS. So I created this “ggsrun”. **The detail information and how to get this are https://github.

CLI Tool - gogauth

Released a CLI tool for easily retrieving accesstoken from Google OAuth2. The title is gogauth. When I have seen stackoverflow, I knew that it is difficult to retrieve accesstoken from Google OAuth2. So I made this. Features of this CLI tool are as follows. Retrieves easily accesstoken from Google OAuth2 for using Drive API. If you have PhantomeJS, this retrieves “code” from Google using it. So you don't need to launch your browser for retrieving “code”.
