To change the color scheme of the Default theme MONO

MONO's HTML and CSS have been significantly updated in v3.07.5.
Therefore, if you use a CSS file older than v3.07.5, some designs will not be displayed correctly.
For example, footers and catalogs don't look as intended.
If you want to change only the color scheme, please use the SCSS for development.

css/dev/sass

It's easy to change the color scheme because the settings are separated for the color scheme and other designs.
However, an environment that can handle SCSS is required.
For example, the free Visual Studio Code and its extension, DartJS Sass Compiler and Sass Watcher.

Use "Lightbox" for pop-up displays

"Luminous" which was used to display popup images, The LICENSE file has been removed from the repository, so LICENSE is now unknown. To resolve this issue, use a "Lightbox" to display the popup. I'm customizing the "Lightbox" to create a "luminous" like popup.

2024/01/30 v6.21.1

Fixed an issue where it would become impossible to post if cookies disappeared while drawing

The system that matches the cookie value set in HTML with the actual cookie value has been abolished. Even if the cookie does not exist at the time of posting, it is now possible to reissue the user code cookie and post. I believe that this not only addresses the issue of cookies disappearing from the user's browser, but also the issue of cookies not being able to be verified due to the server's WAF settings. Also, information was packed in the extension header of Shi-Painter and PaintBBS NEO, but we have switched to a method of obtaining it with GET parameters instead of via the extension header. To maintain compatibility, if it is not possible to obtain with GET, it is now possible to obtain with extension header.

2023/10/23 v6.10.6

The conversion conditions from PNG to JPEG have changed.

Previously, both the drawn image and the uploaded image were converted from PNG to JPEG when the IMAGE_SIZE setting was exceeded, but now only the uploaded image is affected by the setting.

If an error occurs and you cannot post because the posting capacity limit of MAX_KB is exceeded, both the drawn image and the uploaded image will be converted from PNG to JPEG. After conversion, if the file size is reduced to a size that can be posted, it will be posted in JPEG format.

2023/10/21 v6.10.2

It is now possible to configure the minimum width and height for drawing.

New setting items have been added to config.php.

Previously, with POTI-board, if 10,000 comments were recorded in the log file, even if only one comment was displayed on the reply screen, it would read the data for 10,000 comments. To solve this problem, we have made it possible to retrieve only the necessary parts from the log file when displaying the reply screen or catalog screen.

Fixed bugs.

2023/07/13 v5.63.3

You can now set the width and height of the window that opens when sharing on SNS in config.php.

Added a new setting item to config.php.

""

// Width and height of window to open when SNS sharing

//window width initial value 350 define("SNS_WINDOW_WIDTH","350"); //window height initial value 490 define("SNS_WINDOW_HEIGHT","490");

""

When adding a server for SNS sharing, the height of the shared screen window was insufficient and scrolling was sometimes required. Solved the problem by making it possible to set the width and height of the shared screen of the server list when sharing with SNS. If the above setting items do not exist in config.php, the default values of 350px width and 490px height will be applied.

Change log (timezone: Asia/Tokyo, UTC+09:00)

[2023/07/12] v5.63.2

Improved selection operability of SNS server to share posts

image

Servers to share can be selected not only directly above the label string, but also by tapping the right margin of the label.

[2023/07/11] v5.63.1

Replace search.php with search.inc.php

The structure of jsearch.php has been fundamentally overhauled, modified and incorporated into potiboard.php. Search results that were previously displayed with a URL like "search.php?". The URL will be changed like "potiboard.php?mode=search&".

Externalize and standardize CSS switching part of templates MONO

templates/mono/parts/style-switcher.blade.php contains the following parts that have been written in many templates so far.

<style>
body{
    visibility: hidden;
}
</style>
<noscript>
    <style>
        body{
            visibility: visible;

<link rel="stylesheet" href="https://github.com/satopian/poti-kaini-EN/blob/main/{{$skindir}}css/mono_mayo.css?{{$ver}}" id="css3" disabled>

Also set CSS visibility: hidden; here to hide the screen until the DOM and JavaScript have finished loading. This prevents MONO's color settings from temporarily appearing in a different color scheme.

Search is not case sensitive

Name searches are now case insensitive when the exact match option is selected.

[2023/07/08] v5.62.2

Bug fixes

Search function was not working. This bug was introduced in v5.58.10 and fixed in v5.62.2.

From "Tweet button" to "Twitter", "Mastodon" and "Misskey" sharing.

In addition to "Twitter", you can now share posts on short-text posting SNS such as "Mastodon" and "Misskey".

image

You can also change it to a conventional tweet button by setting it in config.php. You can also edit the list of "Mastodon" and "Misskey" servers.

/* ---------- SNS share function advanced settings ---------- */

//Include Mastodon and Misskey servers in the share function
// (1: Include, 0: Do not include)
define("SWITCH_SNS","1");

// Servers displayed in the list when sharing on SNS
//Example ["display name","https://example.com (SNS server url)"], (comma is required at the end)

$servers =

If this setting item does not exist in config.php, the above setting will be applied by default.
If you do not need detailed settings, please use the config.php you are currently using as it is.

230307_continue drawing_post in the same thread

Added a "Post in the same thread" checkbox. However, in the case of "image replacement", there is no choice but to post in the same thread, so this option is unnecessary.

Therefore, I used JavaScript to display the "Post in the same thread" checkbox only when a new post is selected.

When a user has the same host name and IP address, we made it possible to specify a few characters from the front of the IP address displayed as the host name and reject it with a prefix match.

$badhost =["example.com","100.100.200"];

If set like this:

"example.com" will be rejected with a suffix match, and "100.100.200" will be rejected with a prefix match.

You can now configure whether or not to use the URL input field in config.php.

// Use URL input field (Yes: 1, No: 0)
define("USE_URL_INPUT_FIELD", "1");
//No: 0, the URL field disappears from the form input fields.
// Even if the form is faked, the URL will not be entered.

In addition to prohibiting the writing of URLs in the text, if you can also make it impossible to write URLs in the URL field, you can eliminate advertisement spam whose purpose is to write URLs. URL judgment of URL writing prohibition in the text is quite strict, so even if http:// is omitted, it should be almost impossible to write URL of advertisement spam.

Fixed an issue where the template could not be sent due to a JavaScript error when the URL or subject fields did not exist.

It's not a bug, but I've rewritten the JavaScript so that it works fine even if the template is modified by the user.

In PaintBBS NEO, improved so that the screen does not move up and down when manipulating the canvas area such as copy and layer combination.

If the width of the terminal is large compared to the canvas size, it will not scroll even if you grab the mesh of NEO. This is because the screen moves up and down when copying, layer merging, and Bz curve operations. However, you can now grab and scroll the mesh when zooming in with pinch zoom. This is to avoid inoperability. These are implemented with inline JavaScript in NEO's paint screen, so you'll need to update the paint screen template.

Bug fixes

[2023/01/14] v5.55.8.2

Bug fix

Fixed a bug where setting the minimum number of seconds required to draw would cause all alerts that should have been displayed as "15 sec" to be displayed as "0 seconds". Even if this bug exists, if you set it to 60 seconds, you can post normally when it exceeds 60 seconds. The problem was that the remaining time was not displayed accurately, and it was all "remaining 0 sec".

Changed communication of PaintBBS NEO from raw data to formData to avoid false positive error by WAF.

paint.blade.php

A parameter has been added to switch to the formData submit mode.

Changed the config.php

Until now, it was not possible to remove PaintBBS NEO from apps that use it, but now you can choose to use or not use NEO. If you set it to not use all, it will be a setting that does not use the drawing function. You can also set it to use only Klecks or only ChickenPaint. When there is only one app to use, the pull-down menu for app selection disappears and the screen becomes clean.

Limited by drawing time

For example, if you want to reject submissions with only lines drawn in less than 1 minute,

// Security timer (unit: seconds). If not set, use ""
define("SECURITY_TIMER", "");

It was possible to specify the minimum required drawing time with , but until now, it was effective only for Shi-Painter and PaintBBS NEO. With this update, ChickenPaint and Klecks now have this setting enabled. In the old method, when there was a violation, it was possible to jump to another site (for example, the Metropolitan Police Department site), but instead of that method, an alert will open "Please draw for another 30 seconds.".

When using Shii applet and PaintBBS NEO, the behavior of rejection due to the time required for drawing or the number of steps required has been changed.

・shi-chan has developed a function to redirect the drawing screen to the police site when the drawing time is short or the number of drawing processes is small. However, this feature was impractical and of no use. Therefore, instead of suddenly jumping to the specified URL from the drawing screen, we changed the specification to display an alert on the drawing screen that "drawing time is too short" and "the number of steps is low".

![image](https://user-images.githubusercontent.com/44894014/160145766-395c519f-e90e-4397-a92e-03005648906e.png)

- Translated Klecks into Japanese.
I was able to bundle a Japanese version with POTI-board.
This new version of Klecks will automatically detect your browser's language priority and switch languages ​​for you.
You can also specify the language to use regardless of the browser language setting.
You can select English, German, or Japanese.
Chinese is only in Simplified Chinese and details are still in English.
Japanese translation resources have already been merged into the klecks repository.

### The download button for the application-specific file has been created.
![image](https://user-images.githubusercontent.com/44894014/160227733-b57a5783-d95a-4648-b484-5e065b2b7402.png)

#### App-specific format list
- `. Pch` file (PaintBBS)
- `. Chi` file (ChickenPaint)
- `. Psd` file (Klecks)

The file containing the layer information for Klecks is a `.psd` file in Photoshop format.
The downloaded `.psd` file can be opened by CSP, SAI and many other apps.
`.pch` and` .chi` can be opened with NEO and ChickenPaint, respectively.
If you attach `.pch`,` .chi`, `.psd` from the administrator posting screen and press the paint button, you can load it on the canvas and post it.

#### Transparent PNG, change the transparent part of the thumbnail of transparent GIF to white

- Fixed the problem that the transparent part of transparent PNG was black when it was converted to JPEG.
It is not a mistake that the transparent color is black, but since it often results in unintended results, when converting from transparent GIF or transparent PNG to JPEG, the transparent color is converted to white.

### Bug fixes

- Fixed the case where a minor error occurred when operating the upload format specific to the paint application used when logging in to the administrator, and the automatic deletion function of unnecessary temporary files such as pch, chi, and psd.
### BladeOne update
Updated template engine BladeOne to v4.5.

## [2022/03/12] v5.12.0
### Bug fixes
- Fixed the issues that the menu could not be operated with Apple Pencil.
Fixed that the menu operation of ChickenPaint and Klecks could not be operated with.
It was caused by Javascript added to the paint related template in v3.19.5.
I deleted the corresponding Javascript and confirmed that it works normally.
### Updated Klecks
- Updated Klecks to the latest version.
A new brush has been added. You can now do mirror painting.

## [2022/03/8] v5.10.0

### new function
- You can use the new painting app Klecks.

![image](https://user-images.githubusercontent.com/44894014/157234120-d806d24f-2f2b-4600-9d29-515a5743efd6.png)

Easy-to-understand UI, powerful brushes, and filter functions.
You can use 8 layers.
### fix
Many minor bugs have been fixed.

## [2022/02/10] v5.05.0

### URL blacklists
When the character string specified by the "String blacklists" exists in the URL, it is now rejected.
In addition, we have added a "URL blacklists" .

// URL blacklists $badurl = array("example.com","www.example.com");


Previously, no spam word checking was done on the URL.

### Older threads don't show links to draw more. Do not allow the continuation to be drawn.

There was a function to lock the editing of articles that exceeded the specified number of days, but I was able to draw the continuation.
I created these settings because the article will be modified if the password is compromised by a third party.
Even if the article is locked, it can be deleted by the user.
In addition, the administrator can edit even after the specified number of days.

However, I think that some people may be in trouble if the lock is applied within a certain number of days.

`define ('ELAPSED_DAYS', '365');`

Threads older than 1 year will be locked in `365`,

`define ('ELAPSED_DAYS', '0');`

If set to `0`, it will not be locked.

- If the specified number of days has passed while drawing, it will be a new post.
Also, when the thread is deleted while drawing, it will be a new post.

## [2022/01/27] v5.01.03
### Change to BladeOne for template engine

I changed the template engine to BladeOne because I get a deprecated error from Skinny.php in PHP8.1 environment.
However, that means that the templates will be incompatible.
Templates with the extension `HTML` have been replaced with templates with the extension `blade.php`.
When you open the content, it's not much different from a traditional template. However, it may seem difficult because the extension is not HTML. 

### What has changed due to the change of the template engine
#### PHP7.4
- I was developing it to work in PHP5.6 environment, but I found that v4.2 of BladeOne only works in PHP7.4 or higher environment.
POTI-board EVO v5.x requires PHP 7.4 or higher.

#### Information for those who customize and use templates.
The thread display process has changed significantly.
Previously, there was processing for the parent of the thread, and there was separate processing for reply.

In v5.x, the loop of the array of one thread is ended at once.

It then treats the first loop as the parent of the thread.
Specifically, it looks like the following.

@foreach ($ress as $res)
 {{-- Parent article header -}}
@if ($loop->first)
{{-- First loop -}}
<h2 class="article_title"><a href="https://github.com/satopian/poti-kaini-EN/blob/main/{{$self}}?res={{$ress[0]['no']}}">[{{$ress[0]['no']}}]
        {{$ress[0]['sub']}}</a></h2>

@else
<hr>
{{-- article header for reply -}}
<div class="res_article_wrap">
    <div class="res_article_title">[{{$res['no']}}] {{$res['sub']}}</div>
    @endif


`@if ($loop->first)` is true for the first loop of the thread.
When `@if ($loop->first)` is true, it is processed as the parent of the thread.
The `<h2>` tag of the title that is displayed differently only when it is the parent of the thread is put in that place.

If you install the extension [laravel-blade](https://marketplace.visualstudio.com/items?itemName=cjhowe7.laravel-blade&ssr=false#review-details) in a free editor called VScode, the editor screen will appear. Switch to a color scheme optimized for the blade syntax.
Both the extension and the editor itself can be used free of charge.
### Files that have changed
all.
## Looking ahead for a few years
We apologize for the incompatibility of the template and the resetting of config.php, but we hope you understand it.

Also, please use the PHP script for the Oekaki bulletin board called [Petit Note](https://github.com/satopian/Petit_Note), which was newly recreated from scratch.

## [2021/12/22] v3.19.5

- Added the ability to display images of the next and previous threads in the reply view.  

![image](https://user-images.githubusercontent.com/44894014/147068447-9fda9fbe-bfbe-473a-b318-72be33f54273.png)

- When you continue from the Reply image with a "new post", that image becomes the Reply image.  
Previously, if you continue and draw from the image of Reply, a new thread was created.  

- After replying, the screen of each thread that replied is now displayed.
Previously, the top page was displayed regardless of where you replied to the thread.
- Changed the display method when editing / deleting in reply mode or catalog mode and completing the work.
For example, when the edit / delete work is completed on the second page of the catalog mode, the second page of the catalog mode is displayed.
Until now, the top page was displayed.
- Individual threads are now displayed when you continue drawing and the post is complete.
Until now, the top page was displayed.
If the image you want to continue is many pages away from the top page, you had to find the image from many pages.

- ChickenPaint Swipe a specific part of the screen to prevent it from moving up or down. The relevant parts are controlled by JavaScript.  

## [2021/12/04] v3.15.3

- Updated index.php required for new installations.  
Even if the PHP version is PHP5.3 or lower, an error message will be displayed indicating that it will not work because the PHP version is low.  
Previously it was a fatal PHP error.  

- Fixed an issue where long press the ChickenPaint's palette with the pen would open an unwanted mouse right-click menu.

- Fixed an issue where the screen would move up and down when copying and layer merging with PaintBBS NEO.  
If you select a rectangle to perform a copy and layer combination operation, the pen may protrude slightly from the canvas.  
At this time, the PaintBBS NEO's canvas may move up and down.  
Occurs when using Windows ink or Apple Pencil.  
If a screen width wider than the iPad is detected, the screen will not move even if you swipe the mesh part around the canvas of PaintBBSNEO.  
When using a smartphone, the operation is the same as before. Because if you want to pinch out the canvas and zoom in,If you cannot swipe, you cannot operate.    

Please update `mono_paint.html` to resolve these issues.

- picpost.php
Fixed false positives for languages.

- Many translations have been improved.

## [2021/11/23] v3.15.2
### Updated contents of `potiboard.php`

- Chi file deletion process after upload painting  
I added it because there was no process to delete the chi file after uploading the ChickenPaint-specific file and the chi format file and loading it on the canvas in the administrator's post.  
This fix removes it from the temporary directory 5 minutes after uploading. Prior to this fix, files that were no longer needed were deleted after a few days.  
- The HTML ALT for images has been fixed. The HTML translation of the theme has been improved.  

## [2021/11/16] v3.12.2

### `potiboard.php` updates

- Fixed the calculation method of the width and height of the thumbnail image and the width and height of the HTML image when drawing the continuation.
The setting value of connfig.php is set as the maximum value and the calculation is restarted from the beginning.
In ChickenPaint, you can change the height and width of the image by rotating it, but until now, the size of the thumbnail image became smaller each time it was rotated.
- The actual canvas size is now set in the cookie. Previously, the value entered by the user was set as is. Since there is a maximum value for the canvas size, for example, when the maximum is 800px, even if you enter 8000px, the actual canvas size that opens is 800px.
Previously, the cookie was set to 8000px even in such cases.
- An error is now returned when a file name with an invalid length is entered.
- Checks the length of the reply number and returns an error if the length is incorrect.
- Fixed the specification that the full text of the parent's comment is displayed in the description of the article displayed on the reply screen, and now omits 300 bytes or more.
- The translation has been improved.

Please update `potiboard.php`.
### `picpost.php` and `save.php` updates
- In order to mitigate unauthorized posting from external sites, the usercode set in the usercode and cookie during post processing is now checked.

Please update `picpost.php` and `save.php`.

## [2021/10/30] v3.10.0 Fixed a serious bug

- All versions of POTI-board prior to v3.09.5 have a serious bug.  
You may lose all log files.

For those who are using POTI-board v2.  
You cannot use all the functions of v3 system just by replacing `potiboard.php`, but you can deal with this problem.  

Please update `potiboard.php` by overwriting.

### [2021/10/27] v3.09.5

- To prevent the use of weak passwords, an error message will be displayed when the password is 5 characters or less. The error message is "Password is too short. At least 6 characters."
- In order to prevent tampering with articles by third parties, the function to lock replies to threads older than the set number of days has been expanded to lock editing of old articles.
You can delete it. In addition, the administrator can edit and delete as before.

- If you used the old config.php that doesn't have the following settings, you had to check or uncheck [no_imane].  
>// Use to the checkbox of [no_imane], do:'1', do not:'0'  
define('USE_CHECK_NO_FILE', '0');  

we changed this default value from "do:'1'" to "do not:'0'".  
Previously, even if you were using a new theme HTML file, you had to check or uncheck "[no_imane]" when the version of config.php was old.  
- Changing the copyright link on the site. [https://paintbbs.sakura.ne.jp/poti/](https://paintbbs.sakura.ne.jp/poti/)

Click the thread title to open the reply screen .

  - Those files are Not allowed to change when bundling the Shi-Painter applet.
  - So I made Readme_Shichan_utf-8.html and readme_pch_utf-8.html.
  - Just changed the character code to UTF-8. (Information for developers are written in.)

### [2020/12/20] theme -> mono_paint.html

- translating project started.
  - config.php, picpost.php, and security_c.html were done.
  - readme.txt, potiboard.php, and search.php is not yet.
  - theme has a problem. I couldn't translate a short word well.
