Tutorial Contents

In this tutorial we will add two new command for our bot. Our first command will show the all account datas with account image in the message embed (accdatas). To do this, we will use the commands we have prepared in our previous lessons in a single command (reputation, vote power, last vote, follower,follows etc.). Our second command will show the all bot commands for to help the user (help).

New Command for All Account Datas with Account Image (accdata)

Now we will add a new command to see the all account datas with account image in the message embed.

Now, let's write the "else if" section of our command "app.js" file.

Code:

else if (msgorg.startsWith(prefix + 'accdata')) {

}

Now we will create a variable called "accountname". We will receive our message in this variable, and we will delete the "$accdata" section.

Code:

let accountname = msgorg.replace(prefix + 'accfow ','');

In this way we have successfully acquired steem account name.

Now we can create a request for steem account datas with steem.js. And I get steem account profile name and profile image to our variables.

Code:

---

steemjs.api.getAccounts([accountname],

function(err,result)

{

if(result["0"] === undefined)

{

console.log("Invalid Acccount ID");

message.channel.send('Invalid Acccount ID');

}

else

{

let profile = JSON.parse(result[0].json_metadata).profile;

let profile_image = profile.profile_image;

let name = profile.name;

if (name === undefined)

{

name = result[0].name;

}

---

In this way we have successfully acquired steem account datas. And we gave "name" and "profile_image" variables account values.

Now, we will take the account reputation score of to our "reputation" variable. And calculate the power of the vote to account and we will take our "vtpower" variable.

Code:

---

let reputation = steemjs.formatter.reputation(result["0"].reputation);

var secondsago = (new Date - new Date(result[0].last_vote_time + "Z")) / 1000;

var vpow = result[0].voting_power + (10000 * secondsago / 432000);

vtpower = Math.min(vpow / 100, 100).toFixed(2);

---

Now we will calculate our steem power,delegated_steem_power and take it to our variables.

Code:

---

var vesting_shares, delegated_vesting_shares, received_vesting_shares, total_vesting_shares , total_vesting_fund_steem=null;

vesting_shares = result[0].vesting_shares;

delegated_vesting_shares = result[0].delegated_vesting_shares;

received_vesting_shares = result[0].received_vesting_shares;

steemjs.api.getDynamicGlobalProperties(function(err, gresult) {

total_vesting_shares=gresult.total_vesting_shares;

total_vesting_fund=gresult.total_vesting_fund_steem;

var steem_power = steemjs.formatter.vestToSteem(vesting_shares, total_vesting_shares, total_vesting_fund);

var delegated_steem_power = steemjs.formatter.vestToSteem((received_vesting_shares.split(' ')[0]-delegated_vesting_shares.split(' ')[0])+' VESTS', total_vesting_shares, total_vesting_fund);

---

In our code above, after we got the values we needed for our datas, we made our calculations and got the results of our variables.

Now, we will take the account created day of to our "accountcreateddays" variable. And we will get our last vote date and time in our variable "lastvote".

Code:

---

var today= moment(Date.now());

var accountcreated = moment(result[0].created);

var accountcreateddays = today.diff(accountcreated, 'days');

var lastvote = moment(result[0].last_vote_time).add(3,'hours');

---

We got account last vote date time and account creation date to our variables.

Now, we will take the account follow and followers count of to our variables.

Code:

---

steemjs.api.getFollowCountAsync((accountname),

function(err,fresult)

{

var follower_count = fresult.follower_count;

var following_count = fresult.following_count;

})

---

Now we will prepare and send our message embed.

Code:

---

const embed = new Discord.RichEmbed()

.setThumbnail(profile_image)

.setColor(0x5795FE)

.setAuthor(name)

.addField('Reputation',reputation)

.addField('Account Created',accountcreateddays + ' days ago')

.addField('Steem Power',(steem_power+delegated_steem_power).toFixed(2) + ' SP ' + '(' + steem_power.toFixed(2) + ' / ' + delegated_steem_power.toFixed(2) + ')')

.addField('Voting Power',vtpower)

.addField('Last Vote',lastvote.format("YYYY-MM-DD HH:mm"))

.addField('Followers',follower_count)

.addField('Follows',following_count);

message.channel.send(embed);

---

We successfully created and sent our embed with all account datas.

---

Command Discord View:

---

New Command Help (help)

Now we will add a "help" command to see all our commands and their usages. This will make it easier for our users to use Parsbot commands.

Now, let's write the "else if" section of our command. And I add a image for our embed view.

Code:

---

else if (msg === prefix + 'HELP') {

var help_image = "https://i.hizliresim.com/nOW20l.png";

}

---

Now we will prepare and send our message embed.

Code:

---

const embed = new Discord.RichEmbed()

.setThumbnail(help_image)

.setColor(0xFEC057)

.setAuthor('Help')

.addField('Ping','Usage:$ping')

.addField('Hi','Usage:$hi')

.addField('Merhaba','Usage:$merhaba')

.addField('Selam','Usage:$selam')

.addField('Price','Usage:$price steem-dollars')

.addField('Account Reputation Score','Usage:$rep accountname')

.addField('Account Voting Power','Usage:$vpower accountname')

.addField('Account Created','Usage:$accreated accountname')

.addField('Account Steem Power','Usage:$accspower accountname')

.addField('Account Follow/Followers','Usage:$accfow accountname')

.addField('Account Last Vote','Usage:$accltvote accountname')

.addField('Account All Data','Usage:$accdata accountname')

message.channel.send(embed);

---

We added all our commands and uses to our embed and sent them.

Our help command is complete.

Command Discord View:

---

Run and test Parsbot

Now we have to run and test our discord bot.

Open cmd and write "cd yourbotdirectory" and press enter. I write "cd C:\Users\gffdg\Desktop\Discord Pars Bot\parsbot".

Now we will run our app.js file with node.

node app.js

Our bot started successfully and printed "Pars Bot started" message on our ready event.
