Strawberry Src
A slightly-less-simple code & text editor
Author: Matt Sutton / @xietanu.bsky.social
Overview
Strawberry Src is intended as an equivalent app to Picotron's in-built code or text editors, with a few quality or life improvements to navigating and editting code and text easier.
Important notes
Sandboxing
For now, Strawberry Src needs to be unsandboxed - it seems there are some issues I missed in testing when running sandboxed. I would like to get Strawberry Src working sandboxed, but an initial look suggests at least some of the issues are outside of my control and are being caused by how the current version of Picotron not correctly handing over permissions and/or other bugs in Picotron's file wrangling code. I'll update what I can and at least put a warning in place if running sandboxed.
You can unsandbox the cart by either loading it using load -u #strawberry_src-1, or by right-clicking on a local copy and clicking 'about strawberry_src.p64', then unchecking the box in the bottom-left corner.
Default app
There's a known bug in Picotron's filenav at the moment that means that even if you try to open a text or lua file with Strawberry Src, it will generally open in your default app anyway. To overcome this, the only real option is unfortunately to set Strawberry Src to be your default app for editing the files you want to use it with.
You can do this with this command in the terminal: default_app <file_extension> <path_to_strawberry_src>.
e.g. default_app lua /strawberry_src.p64
Unfortunately, this one is out of my control. The bug is logged as part of this thread: https://www.lexaloffle.com/bbs/?page=9&tid=140647
Make sure you've not got the same file opened more than once
Also, make sure you've closed files in the in-built code editor (or close the editor entirely) before editting them in Strawberry Src.
The system should notify you about this, but it could lead to changes not being saved.
Remember the code editor automatically opens main.lua when you start Picotron.
Features
Note, most features can be enabled/disabled/modified in the settings menu.
Syntax highlighting
Along with all the same highlighing as in-built code editor, user defined functions (within the same file), local variables and function variables are now all highlighted.
Syntax error highlighting
If there is a syntax error in your code, this will be highlighted with a red squiggly line. Hovering over this will give more information about the error.
Additionally, the footer indicates if there is an error, and one what line.
Function tooltips
Hovering over a function gives information about it. For inbuilt functions, these are drawn from the documentation. For user-defined function, they are drawn from comments immediately before or after the relevant function.
Autocomplete
When typing code, if you pause a list of suggestions to complete the currently typed section will appear. You can select an option with the up/down arrows and accept it with tab.
The suggestions are drawn from inbuilt functions, user-defined function and current local and function variables.
Bookmarks
Bookmarks allow for quickly jumping around between points in the current file - most commonly, jumping to the start of function definitions, but they can be defined quite flexibly, and even grouped.
Bookmarks for the current file can be shown / hidden with the bookmark button in the top right.
In code files, bookmarks are automatically created for each function. In text files, they are created for any line starting formatted like: '## title' or ' title '.
Additionally, in code files, you can create a bookmark at any point in the code by adding a comment formatted like: '--[[BOOKMARK:title]]'
Bookmarks can also be grouped. In code files, if you're using modules or classes, their associated functions will automatically be grouped. E.g. 'function module.func()' would be placed in the 'module' group, or 'function class:func()' would be placed in the 'class' group.
Additionally, groups can be manually created using a comment formatted like: '--[[GROUP:title]]'. Groups are ended either by starting a new group, or with '--[[GROUP]]'.
In text files, groups are started using a line formatted like '# title' or ' title '.
As an example, this file uses them!
The formatting of the bookmarks has been done to try to be broadly compatible and not cause any issues when viewing files in a another program. Happy to take feedback on if this could work better!
Rainbow brackets
Matching brackets are highlighted by colour, with colours varying by level. Mismatched closing brackets are shown in white for easy identification. This can be turned on/off in the settings.
Changeable themes
There are currently 4 themes that can be selected, and can be set separately for editing text or code. Note that the system theme draws its colours from your current system theme.
Smooth scrolling
Scrolling is now smooth. Why was this so hard to implement?
This can be enabled/disabled in the settings.
Line wrapping
In text files, lines can now be automatically wrapped.
This can be enabled/disabled in the settings.

How does this relate to SpaghettiCode?
I built this editor as an effort to de-scope and create a new, more robust basic editor. This will form the core of the next version of SpaghettiCode, which I intend to continue to develop as a more complete development environment. However, I think it's a pretty good editor by itself and addresses a lot of the issues with SpaghettiCode's central editor (like maintaining good performance on large files).

I've already started playing around with it, and didn't realize it was by the same person behind Spaghetticode! I haven't used either very much, but this feels very good to use so far. The addition of bookmarks is very nice! One thing I would like to see in the future is the ability to collapse nested code to save space.
