Code quality and profiling

• Improve a few instances where code did nothing (ineffassign).

• Fix all typos in comments, as reported by Go Report Card.
• Update all dependencies.

• Fix an issue with using o as a man page viewer on Arch Linux (using MANPAGER=o).

• Make it possible to insert a symbol by pressing ctrl-_ and type in a 2-letter digraph (same digraphs as ViM uses).
• Use timestamps in the location history, so that it can be culled/rotated and not grow too much over time.
• Make it possible to press ctrl-f and search for a blank string or a space.
• Disallow saving a file concurrently and then exiting the editor at the same time.
• If ctrl-t is pressed while editing C or C++, but there is no corresponding source or header file to switch to, use the macro behavior instead.
• Make it possible to press esc repeatedly to bring up the ctrl-o menu.
• Add an -n flag for not writing to ~/.cache/o (where the location history, search history, game highscore etc. are kept).
• Improve how the Markdown table editor draws tables.
• Drop the initial status bar help message, since both --help and a man page are available.
• Improve the help output and help text.
• Some refactoring.
• Update the documentation.
• Update the dependencies.

Markdown Table Editor

• Improve the look of the Markdown table editor.
• When editing Markdown tables, trim the right column if it is empty.
• When pressing ctrl-t on an empty line in a Markdown table, insert an empty table and open the Markdown table editor.
• Display "quick help" the first time the Markdown table editor is shown, at the bottom of the screen.

The VTE/GUI front-end application

• Run in fullscreen mode by default.
• Use a slightly smaller default font on macOS.
• Fix the application so that the edig symlink uses the intended theme.
• Make starting and quitting more responsive on both macOS and Linux.

General

• Add initial support for the Mojo programming language.
• Minor improvements for the Nim programming language.
• Fix the Makefile for macOS.
• Rename two symlinks so that they are shorter.
• If the "fix as you type" feature is enable and an error occurs, disable the feature.
• Update dependencies.
• Update documentation.
• Update the web page.

• Add a simple web page (https://orbiton.zip).
• Add build flags to the Makefile.
• Require a total of 5 repeated presses of Esc as the alternative method of launching the ctrl-o menu (up from 4). This is to not get in the way of clearing a recorded macro by pressing Esc repeatedly.
• Make it possible to press ctrl-s while playing the built-in game, to save the pixels as a .png file, as an easteregg within an easteregg.
• Update the man page and documentation.

• Fix the release script, ref. #15.
• Fix an issue with pressing backspace near the end of long lines, which made the horizontal scrolling misbehave.
• Let o also work as a man page viewer on OpenSUSE.
• Add documentation for how to set up o on OpenSUSE.
• For the GUI/VTE frontend og, use usleep instead of sleep.
• Let ctrl-w format Markdown tables, when the cursor is on one.
• Let ctrl-s to save the file also work when editing a Markdown table with the Markdown table editor.
• Only update the Markdown table when exiting the Markdown table editor if changes were made.
• Do not let ctrl-n jump to matching parentheses, only ctrl-p.
• Make the theme selection in the ctrl-o menu more descriptive.
• Let the ctrl-o menu also show the current program version.
• When pasting a file on the command line with o -p, mark the resulting as executable if it is a script (if it has a .sh file extension, is pasted in a bin directory like /usr/bin or if the file contents starts with a shebang).
• Add O_THEME as an alias for the THEME environment variable name.
• Update dependencies.

• Use the betteralign utility to optimize structs.
• Improve the man-page functionality so that it also works well on Fedora.
• Always use tabs for makefiles.
• Let ctrl-n and ctrl-p jump to matching parenthesis or bracket, but only if the cursor is on one and if the previous keypress was not ctrl-n/ctrl-p. This way, one can navigate to a parenthesis with the arrow keys and jump to the matching one with ctrl-n/ctrl-p, but scrolling down repeatedly with ctrl-n or up with ctrl-p will not be stopped.
• Let ctrl-g show a friendly help message, but when ctrl-g is pressed a third time, let it either go to definition or toggle the status bar at the bottom. Go to definition is a new experimental feature, is only tested for Go code, and currently only works within the same file.
• Press Esc 4 times in a row as an alternative way of opening the ctrl-o menu.
• Let ctrl-space render Markdown files to HTML.
• Add a menu option in the ctrl-o menu for rendering Markdown files to PDF with pandoc.
• Add a "fix as you type" feature that can be enabled in the ctrl-o menu if the OPENAI_API_KEY, OPENAI_KEY or CHATGPT_API_KEY environment variables is set to a valid OpenAI API key. Every time return is pressed, the line will be sent to ChatGPT and be corrected. This is an experimental feature.
• Also save the search history for "search and replace" (ctrl-f, then the tab key and then return).
• Fix a bug in the WordAtCursor function.
• Add a command line flag for clearing all file locks.
• Show a status message when pasting through portals.
• Add a Markdown table editor that can be activated by pressing ctrl-t while the cursor is on a Markdown table. Within the table editor, ctrl-n can be used for adding columns, ctrl-d can be used for deleting empty columns. return, tab and the arrow keys also work, see the README.md file for more information.
• Let ctrl-w format Markdown tables, if the cursor is on one.
• Add a menu option for sorting a block of lines.
• Minor improvements to the Agda symbol insertion menu.
• Update dependencies.
• Update documentation.
