Message processing

PLEASE NOTE!

Message processing is only possible when delivering messages using the copy method. When delivering messages using the built-in Telegram forward mechanism, no content transformation is possible!

New! Transformation with AI

You can freely describe the changes that need to be made to the text of messages, and let the AI do the rest of the work. In this way, you can either change some elements of the text or numbers, or rewrite the text completely anew (for example, in another language, in another style, changing the size but preserving the meaning, analyzing and drawing conclusions, etc.).

See here for how to set this up.

‍

Adding text

With these settings, you can add text before or after the message text.

Where to find

Menu → My forwards → Select source and destination → Edit → Header

Menu → My forwards → Select source and destination → Edit → Footer

Example of adding text at the beginning:

_{Here's what I heard.}

Note that the original message text will continue on the same line as your text. So the message will look like this:

_{Here's what I heard. One day Buddha came...}

If you want the original message text to go on a new line, don't forget to add a line break at the end of your title.

Examples of adding text at the end:

_{Write all questions to support@mail.com}

_{<a href="https://junctionbot.io/">My site</a>}

Please note that if you don't put a line break at the beginning, your text will start on the same line as the original message text.

‍

Cropping and shortening text

Where to find

Menu → My forwards → Select source and destination → Modification → Shorten

Long messages will be shortened to the specified length.

Recommended values: from 150 (Twitter-style posts) to 1000 (multiple paragraphs).

To disable this feature, set this value to 0.

‍

Text replacement

Where to find

Menu → My forwards → Select source and destination → Modification → Replacements

You can set an autoreplace rule that will replace text A in incoming messages with text B (or an empty string if you do not specify text B).

Please note that this setting works only with the message body and buttons, without changing the title (the name of the message) channel, if you enabled its display) or a link to the original message.

‍

Replacing using regular expressions

Alternatively, you can use regular expressions for replacement. To do this, on the replacement settings page, check the RE (Regular Expression) box for the desired replacement.

You can find useful examples of replacements using regular expressions here: Advanced examples.

‍

Regular expression help

For more information on debugging regular expressions, see here.

‍

Adding formatting

Text formatting is done through HTML tags. You can read more about the tags supported by Telegram here.

To add formatting, you need to surround the desired piece of text with the appropriate tags. For example, to make _{a specific piece of text} bold, create a new replacement:

Source:_{specific piece of text}

New value:_{specific piece of text}

‍

You can find useful examples of advanced formatting here: Advanced examples.

‍

Removing formatting

To remove formatting, you first need to understand what the original message text, including tags.

Then you can add the appropriate replacement rules that remove unnecessary tags.

For example, to remove bold from _{the desired piece of text}, enter a new replacement:

Source:_{the desired piece of text}

New value:_{the desired piece of text}

An alternative way to configure via command

Command: _{/replace source the desired piece text the desired piece text}

‍

Premium emoji replacement

Premium emoji are sent using the tag, for example:

(emoji)

You can find out the exact code in one of several ways, for example, by enabling processing reporting in the channel and sending the desired emoji there.

Knowing the exact code, you can use it in replacements or add this emoji to your message using the Header or Footer settings. Please note that to publish premium emoji, the relevant conditions must be met.

‍

Replacing links to the source

Where to find

Menu → My forwards → Select source and destination → Modification → Replace source links

This setting will help you automatically replace links to the source and to messages in the source, without creating replacement rules manually.

‍

Replacing links in text

Links in a message can be of different types, so there is no one universal command. First, we need to determine the link type, and only then can we create the necessary replacement rule. To determine the link type, look at the source code of the message. This is how the bot sees this message when applying the replacement rules.

Option 1.

In the incoming report, we see that the link is set by formatting using the <a> tag. For example:
_{Breaking news!
We won the "Fastest bot in Telegram" award!
<a href="https://junctionbot.io">Welcome to our site!</a>}

Then we need to use this entire structure in the replacement rule.

To simply remove a link from a message, create a replacement, leaving the "New value" field empty:

Source: _{<a href="https://junctionbot.io">Welcome to our site!</a>}

New value: (empty)

‍
To replace one link with another, create this replacement:

Source: _{<a href="https://junctionbot.io">Welcome to our site!</a>}

New value: _{<a href="https://lectumbot.com">Welcome to our site!</a>}

‍

If you want to replace not a specific link, but all possible links specified using <a>, then create the following replacement:

Source: _<a[^<]+</a>

RE (Regular Expression): Yes

New value: (empty)

‍‍

Option 2.

In the received report we see that the link is specified without formatting, just text. Then there will be no <a> tag around the link.
For example:
_{Breakthrough news!
We have won the "Fastest bot in Telegram" award!
Welcome to our website!
https://junctionbot.io}

Then, without further ado, we simply specify the link in the replacement rule.

To remove it, we use a replacement:

Source: _{https://junctionbot.io}

New value: (empty)

‍

To replace with another:

Source: _{https://junctionbot.io}

New value: _{https://lectumbot.com}

‍

If we want to remove any such links, we use a replacement:

Source: _{https:\/\/\S+}

RE (Regular Expression): Yes

New value: (empty)

‍

Any @username links not added by the bot itself can be removed by replacing:

Source: _{@([a-zA-Z0-9=&_\-]+)}

RE (Regular expression): Yes

New value: (empty)

‍

A link to the original post added by the bot itself can be removed in the section: Menu → My forwards → Select source and destination → Source data → Original message link → NONE

‍

Replacing and transforming media

Regular replacements only work with message text and buttons. If you want to replace one image with another or add media to a text message, use the review mode.

How to add watermarks, read here.

You can process media using third-party Telegram bots and then use it in Junction Bot. How to do this, read here.

‍

^New! Adding watermarks

_{Direct or Expert tariffs}

Junction Bot can protect your media in Telegram with watermarks. Add your own watermarks to photos, animations and videos.

Where to find

Menu → My forwards → Select source and destination → Content → Watermark

Select the desired sign from the list of previously uploaded ones.
Check the boxes to indicate which type of content to apply the sign to:
- image
- video
- animation

Create a new watermark

In the section My watermarks select Create new mark. Fill in the fields:

Name of the watermark
Upload file. Only PNG images are supported as watermarks.
Select transparency level - the higher the value, the more transparent the overlay mark will be.
Select scaling mode:
- Fit - fit the watermark to the image borders, reducing it if necessary.
- Cover - enlarge the watermark to fit the image size.
- None - do not reduce or enlarge.
Select how to align the mark.

‍

Name and other data about the source

This setting allows you to add the name of the source channel and other data about the message to the message.

Where to find

Menu → My forwards → Select source and destination → Source data → Source name

Options

^none - do not specify names

^simple - add the name of the source channel as a title (at the beginning of the message)

^bold - add the name in bold as header

^from_only - do not specify the name of the immediate source, but specify the name of the original source (if any)

^id - instead of the name, specify the ID of the message in the source channel

^date - instead of the name, specify the date of publication of the message in the source channel

_{custom value} - replace the channel name with this text (standard Telegram html tags are supported)

Please use the last option carefully, because if the text formatting is violated (for example, by unclosed or unsupported tags), you will stop receiving messages from this channel or they will arrive completely unformatted.

‍

Setting up a link to the original message

This setting allows you to set up a link to the original message to be displayed at the end of the message. This means only the link, which by default is displayed at the bottom of the forwarded message as the @ symbol. If you want to change other links in a post, see here.

Where to find

Menu → My forwards → Select source and destination → Source data → Original message link

Options

^none - do not pass the link

^full - pass the link as is

_{custom value} - hide the link behind this line

‍

Author display settings

This setting only applies to messages that contain an author name.

You can choose how the message author name will be displayed.

Where to find

Menu → My forwards → Select source and destination → Source data → Author

Options

^none - do not specify name

^name - specify name

‍^username - specify @username

^full - specify name and @username

When choosing to specify the name and/or username, the bot will try to make the author's name a link. But this is not always possible and depends on things like the author's privacy settings. Also, in some cases the username can be passed as User#123456.

Another way to preserve the author name when redirecting is not to copy, but to forward messages using the "Forward via account" delivery mode.

An alternative way to set up via commands

Commands: _{/setting author none}, _{/setting author name} etc.

‍

Adding your own buttons

You can add your own URL buttons to forwarded messages.

Important: due to Telegram restrictions, buttons are published only in delivery mode on behalf of the bot (copy_bot).

Where to find

Menu → My forwards → Select source and destination → Content → Add buttons

Options

^none - do not add your own buttons

_{custom value} - add your own buttons

To add your own buttons, in the "Custom value" field, enter the URL of the new button and the text to display on the button, separated by a space. Specify each new button on a new line.

Example:

_{https://junction.space About the project
https://tgchannels.org All channels here}

‍

Alternative way to configure via commands

Command:
_{/setting mybuttons
https://junction.space About the project
https://tgchannels.org All channels here}

‍

Adding feedback buttons

This setting adds feedback buttons to the message (for example, "likes").

Where to find

Menu → My forwards → Select source and destination → Content → Feedback buttons

Options

^none - no buttons

¹ - 👍 button

² - two buttons: 👍 and 👎

_{arbitrary value} - each word of this line will become a separate button

Example: the line _{👍 👎} will give the same effect as the option ²

Example: _{Yes No Possible} - will add 3 buttons "Yes", "No", "Possible"

‍

Alternative way to configure via commands

Command: _{/setting like Yes No Possible}

‍

Using other Telegram bots

If you need functions such as, for example, advanced image processing, etc., then you can embed a bot that performs the desired function in your forwarding rule.

Step 1

Find the Telegram bot you want to use.

Step 2

Configure forwarding from the desired source to this bot.

Step 3

Configure forwarding from the bot to the desired destination channel.

‍

If you need to run multiple sources through a third-party bot and split them into different destinations again, do the following:

Configure redirection from the source to the third-party bot
Add a specific text key for each source to the message, for example SOURCE1
Menu → My forwards → Select source and destination → Header
Value: _SOURCE1
Configure redirection from a third-party bot to an intermediate channel
Add a filter for redirection from a third-party bot to an intermediate channel so that only messages with the key are received
Menu → My forwards → Select source and destination → Filtering → Filters
New text filter mustHave _SOURCE1
Configure redirection from intermediate channel to destination channel
Remove the key when forwarding from intermediate channel to destination channel
Menu → My forwards → Select source and destination → Modification → Replacements
Source: _SOURCE1
New value: (empty)

‍

Manual editing

If you want to manually edit the message you are forwarding, use the review mode.

‍

Advanced processing examples messages

Useful Replacement Settings

Below are expressions for common replacement tasks. Some can be solved without regular expressions, but most require them.

‍

1. Remove the header with the name of the original channel added by the bot:

Where to find

Menu → My forwards → Select source and destination → Source data → Source name → NONE

Alternative setting method via commands

_{/setting header none}

‍

2. Remove the link to the original post added by the bot:

Where to find

Menu → My forwards → Select source and destination → Source data → Original message link → NONE

‍

Regular expression replacements

Where to find

Menu → My forwards → Select source and destination → Modification → Replacements

‍

3. Remove specific links from the message body:

Source: <a href="https://specific-link">the text of this link</a>

RE (Regular Expression): None

New value: (empty)

Alternatively, via command: /replace source_link <a href="https://specific-link">the text of this link</a>

In all messages from the @source channel, it will replace all such links with an empty string.

‍
4. Delete all links in the message body if they are transmitted by formatting:

Source: _<a[^<]+</a>

RE (Regular Expression): No

New value: (empty)

Alternatively, via the command: _{/replacerx source <a[^<]+</a>}

‍

`‍`5. Remove links in the message body that are transmitted simply as text:

Source: _{(http:\/\/|https:\/\/)([a-zA-Z0-9.\/\?=&_]+)}

RE (Regular expression): Yes

New value: (empty)

Alternatively via command: _{/replacerx source (http:\/\/|https:\/\/)([a-zA-Z0-9.\/\?=&_]+)}

‍

‍`‍`6. Remove only links containing only "t.me":

Source: _{(http:\/\/|https:\/\/)(t.me)([a-zA-Z0-9.\/\?=&_]+)}

RE (Regular Expression): Yes

New Value: (empty)

7. Remove username links like @username

Source: _{@([a-zA-Z0-9=&_\-]+)}

RE (Regular Expression): Yes

New value: (empty)

`‍`
8. Remove the entire section of the message that begins with the word "Postscriptum"

Source: _{Postscriptum.*}

RE (Regular Expression): Yes

New value: (empty)

9. Turn a chunk of text "chunk of text" into a link to https://junctionbot.io/

Source: _{chunk of text}

RE (Regular Expression): Yes

New Value: <a href="https://junctionbot.io/">chunk of text</a>

‍‍
10. Remove all numbers of the format "№12345" from the message

Source: _№([0-9]+)

RE (Regular expression): Yes

New value: (empty)

‍`‍`
11. Remove text from captions of all images (forward only images).

All other text messages (without images) will not be forwarded.

Source: _.*

RE (Regular Expression): Yes

New Value: (empty)

`‍`
12. Delete all lines containing the word `keyword`

Source: _{.*\bkeyword\b.*}

RE (Regular Expression): Yes

New Value: (empty)

‍`‍`
13. Remove all empty lines

Source: _

RE (Regular Expression): Yes

New Value: _ 

`‍`
14. Highlight the word `keyword` in bold font.

Source: _keyword

RE (Regular Expression): Yes

New value: _{keyword}

‍`‍`
15. Highlight all numbers in bold font.

Note that in the last argument we substitute the text matched by the RegEx expression using the so-called numbered backreference $1. You can read more about this powerful tool here.

Source: _([0-9]+)

RE (Regular Expression): Yes

New value: _$1

‍
You can highlight the entire message in bold like this:
Source: _(.*)

RE (Regular Expression): Yes

New value: _$1

`‍`
16. Remove all text, leaving only a line of a certain format

Remove all text, leaving only a line of the format "Token: 0xdAC17F958D2ee523a2206206994597C13D831ec7", where the token value can be any address of the ETH20 format.

Source: _{(?s).*(Token: 0x[a-zA-Z0-9]+).*}

RE (Regular Expression): Yes

New Value: _$1

‍
What's going on here?_‍‍

We say that we want to replace all text matching the expression with the value of the first group (_$1). The first group in our case is (_{Token: 0x[a-zA-Z0-9]+}).
The _(?s).* and _.* wrappers make sure that all text around the line we need is replaced. Since _.* applies to a maximum of one line, we add the _(?s) modifier. Thanks to it, _.* will cover all lines before and after the line with the token we need.

‍

Advanced example of changing formatting

Let's assume that we have created a channel that accumulates free trading signals from other channels, and we want to bring all signals to the same format. Example of a message in the source channel:

_{Buy BTC/USD
Stop-Loss at 11000
Take-Profit 1 at 11500
Take-Profit 2 at 11700
Take-Profit 3 at 12000}

We want to format such messages as:

_{BUY
#BTC/USD
SL: 11000 points
TP: 12000 points
Trade at your own risk!}

1. Replace Buy with a space with BUY, a line feed and #. Create a new replacement:

Source: _Buy - don't forget to include a space after the words Buy in the replacement

New value: _BUY # - We will indicate a line feed with the symbol  . You can replace it with a regular line feed.
‍

2. Next, a similar replacement: Stop-Loss at is replaced with SL:

Source: _{Stop-Loss at} - don't forget to include a space after the words Buy

New value: _SL:

‍

3. The next command will be more complicated. We need to remove two lines Take-Profit 1 and Take-Profit 2 and instead of them add the word points to the previous line SL. To do this, we will use a replacement using a regular expression:

Source: _{\nTake-Profit 1.*\n}

RE (Regular expression): Yes

New value: _points

4. Then we replace the line Take-Profit 2 with the price and Take-Profit 3 with TP:

Source: _{Take-Profit 2.*Take-Profit 3}

RE (Regular expression): Yes

New value: _TP:

5. And finally, we add the word points and the line Trade at your own risk! to the end. To do this, we will use the setting Add text to the end of the message:

_{points Trade at your own risk!}

‍
