UNRELEASED

v7.0

In this version, we have switched to KSyntaxHighlighting, the same framework used by the Kate editor. This upgrade results in significantly improved syntax highlighting, a wider selection of color themes, and additional features like code folding. However, due to extensive refactoring, some bugs may arise.

We have also performed some cleanup, introducing several breaking changes. Most users will not be impacted. Only advanced users who depend on command-line options, setting file locations, etc., might experience disruptions. Additionally, if you are using v6.7 or an older version, you should first upgrade to v6.11 and then to v7.0 to prevent data loss.

Breaking Changes

• Legacy setting entries from v6.7 and earlier are no longer automatically migrated to the new ones. (#1308)
• The command line option --no-hot-exit is renamed to --no-restore-session. (#1308)
• The application name is changed from CP Editor to cpeditor. This affects the name of the config directory (the old config files are automatically migrated) and temporary directories, and also things like window class name in Xorg. The log files are also moved to a new location (from /tmp/cpeditorLogFiles to ~/.cache/cpeditor/log on Linux). (#1308)

Added

• Use KSyntaxHighlighting for code highlighting. (#1101)
• Add options to select error/warning messages colors for message logger. (#521 and #1247)

Fixed

• UNIX signal handler is now more robust. (#1166 and #1304)
• Now pressing Home goes to the first non-blank character. When lines are wrapped, now Home and End are based on text lines instead of visual lines. (#774 and #1310)

v6.11

Added

• Brazilian Portuguese translations (#1050)
• Spanish (Mexico) translations (#1131)

Fixed

• Fix that saved file content was not restored after abnormal exit when "Restore last session at startup" is enabled. (#1059 and #1061)
• Now the snippet names are sorted case-insensitively when choosing snippets. (#1063 and #1065)

• Fix that when built with CMake 3.21.1 and Ninja, it results in dupbuild or dependency cycle error. (#941)

Changed

v6.6

The Portable Version

Now we provide the portable version on Windows. The portable version saves the config file in the same directory as the executable file of CP Editor, instead of the system config directory, and you can run it without installtion.

With the portable version, you can easily store it in something like a USB disk, and the configs are always with you no matter you run it on which machine. However, the file paths in the settings can be broken when you change the machine.

Now error linting is available with Language Server. Linting can be helpful when you want to find errors in your code and fix them quickly. You need to install a Language Server program to enable linting. You can set delay for linting, the path to the Languae Server program and its arguments in the Preferences window. You can set different settings for different languages. Please check the manual for more information on how to set this up.

v6.3

The new Preferences Window!

The old preferences window is not very extendable, which has been a big obstacle to add new features for a long time. In this version, we bring a brand new preferences window for you.

In the new preferences window, the settings are organized well in a tree structure. Now you can save the settings for each page separately, and get warned when you try to leave a page without saving the changes. You can discard the changes on the current page, or restore the settings on the current page to the default. What's more, you can search for a setting and go to the corresponding page easily.

If you want to backup your settings file or do something with it, we have to tell you that it has been moved from the home directory to the config directory (on Linux, from $HOME to $HOME/.config/CP Editor). But don't worry, we have been working on keeping backward compatibility, so you won't lose your settings when switching from the old version to the new version.

For the developers, now it's extremely easy to add a new setting. So we'll add more settings with some exciting features in the next version.
