Reddit Mass Comment Editor 作者： Shajirr

This addon allows users to:

• Perform mass search and replace operations on your comments
• Perform mass comment randomization
• Randomize individual comments
• Load comments after a specific comment (via comment ID)
• Filter down comments to a specific subreddit
• Create comment backups (JSON format)
• View a console log of all of its actions

Usage instructions:

Check if you are logged in to Reddit first, that's required.
To open the addon page, click the addon icon.
Then click "Authenticate", which will redirect you to a Reddit page
asking if you will grant access to this app,
which you need to confirm in order to obtain the authentication token.
If that's successful, addon should show your username and
all other functions should become available.

Before doing anything it would be a good idea to use "Export loaded comments" function first, which will create a JSON backup file of all currently loaded comments.

Comment randomization feature replaces all words in your comment with the random words of the same length, as well as replacing all the digits with the random ones. All punctuation/symbols/spaces are kept.

By default the addon will display first 50 loaded comments, and then each 50th one.

Mass edit operations will issue 2 confirmation popups, asking you to confirm that you had saved a provided backup file and checked that it contains valid info.
Single comment edits have no confirmations.

Setting custom CLIENT_ID to have an individual (not shared) request limit

This is optional for now, but might be required later if multiple users would be using the addon at the same time.
First, you need to register your own Reddit app, here:
https://www.reddit.com/prefs/apps/
select "create another app"
name - whatever, but preferably something unique
type: installed app
about url - not needed, leave blank
redirect uri - this is the only important part here, write this address exactly:
https://shajirr.github.io/reddit-comment-scrambler-a/redirect.html
then press "Create app"
that's it, app registered.
Now under app title and "installed app" text you can see a row of some random
letters and numbers - that's the CLIENT_ID.
Copy it, go back to my addon page, press "Set CLIENT_ID"
and paste the copied CLIENT_ID.
Addon will check if its valid, and if it is, then it will be used instead of the default one.

Limitations

• Reddit API only allows about 30 edits per minute, any higher and it causes errors. So editing lots of comments can take a while. If it gets interrupted, you can restart it by copying last edited comment ID and using "After comment:" field to load only comments after it that haven't been edited.
• Multiple users can drain the API request limit - in that case you can register your own Reddit app (takes about 30 seconds) and use its CLIENT_ID to not share the request limit with others
• So far API allows to only load about 1800-1900 last user comments max. There is a possible way to break this limit, by loading comments gotten via GUI search instead, but its not implemented fully yet.

Plans / not yet implemented

• Ability to load comments back from the JSON backup
• Ability to write back the info from loaded comments to Reddit, effectively allowing automatic restoration from the backup file
• Ability to filter comments by time/date
• Add an option to display all loaded comments regardless of their number.
