Proverbs 10 ³ The LORD will not suffer the soul of the righteous to famish: but he casts away the substance of the wicked. ⁴ He becomes poor that deals with a slack hand: but the hand of the diligent makes rich. ⁵ He that gathers in summer is a wise son: but he that sleeps in harvest is a son that causes shame. ⁶ Blessings are on the head of the just: but violence covers the mouth of the wicked.

Usage

Time2BlocksWidgetModule

You can import the widget module to use the pipe, the widget module imports the service module too

import { Time2BlocksWidgetModule } from '@belomonte/time2blocks-ngx';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    Time2BlocksWidgetModule
  ],
  bootstrap: [
    AppComponent
  ]
})
export class AppModule { }

In angular html component:

<span>{{ 1280426887 | time2blocks : 'h [halving], [block] b' | async }}</span>

Time2BlocksServiceModule

You can import only the service module, this will provide Time2BlocksService without the pipe

import { Time2BlocksServiceModule } from '@belomonte/time2blocks-ngx';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    Time2BlocksServiceModule
  ],
  bootstrap: [
    AppComponent
  ]
})
export class AppModule { }

Service usaged

@Directive()
export class AppService implements OnInit {

  constructor(
    private time2BlocksService: Time2BlocksService
  ) { }

  ngOnInit(): void {
    this.time2BlocksService
      .getFromTimestamp(1695915641)
      .then(block => this.format(block))
      .catch(e => console.error(e));

    this.time2BlocksService
      .getFromTimestamp(1695915641)
      .then(block => console.info(block))
      .catch(e => console.error(e));
  }

  format(block: number): void {
    const formatted = this.time2BlocksService.format(block, '[Halving count down:] -%% [to halving] H');
    console.info('formatted', formatted);
  }
}

Formats

| symbol | result | |--------|--------| | h | current halving | | H | next halving | | -h | last halving | B | all blocks | BB | All blocks in format 0,000,000 | b | blocks in this halving | bb | blocks in this halving in format 000,000 | -b | blocks to next halving | -bb | blocks to next halving in format 000,000 | % | blocks in this halving in percentage: 0.0% ~ 100.0%, | %% | blocks in this halving in percentage: 0.00% ~ 100.00%, | %%% | blocks in this halving in percentage: 0.000% ~ 100.000%, | %%%% | blocks in this halving in raw percentage: 0.x ~ 100.x%, 65.4234234234234%, 21.5% | -% | blocks to next halving in percentage: 0.0% ~ 100.0%, | -%% | blocks to next halving in percentage: 0.00% ~ 100.00%, | -%%% | blocks to next halving in percentage: 0.000% ~ 100.000%, | -%%%% | blocks to next halving in raw percentage: 0.x ~ 100.x%, 65.4234234234234%, 21.5%

So, if your format string include the letter h, b or B you should escape this:

blocksFormat(80000, 'h [Halvings], [block] bb') will return: 3 Halvings, block 170,000

blocksFormat(80000, 'h [[Halvings]], [[block]] bb') will return: 3 Halvings, block 170,000
