# ted A text editor. **ted is still very new. There is no nice installer yet (if you want ted, you'll have to build it from source). I'll release installers after testing it a bit more to try to find any remaining bugs.** ## Why? There are a lot of text editors out there. ted doesn't do anything new. I made ted because I wanted a text editor that starts up practically instantaneously, and performs well on reasonably-sized files. ted isn't incredibly complicated, but it does have some nice features you might not find in other editors. ## Supported features (more coming soon) All the keybindings listed below are customizable! - Multiple tabs, each with a different file - Split screen (Ctrl+/, Ctrl+Shift+/) - Auto-indent - Customization of (pretty much) all colours and keyboard commands. - Syntax highlighting for C, C++, Rust, and Python. - Find and replace (with regular expressions!) - Run build command (F4), go to errors - Run any shell command (Ctrl+!) - Go to definition (Ctrl+click) - Go to line (Ctrl+G) - Autocomplete (Ctrl+Space) ## Getting started with ted After installing ted, you can just start using it like you would any other editor. The keyboard shortcuts are mostly what you'd expect them to be (Ctrl+o for open, Ctrl+s for save, etc.). ### Tips - Even if you don't want to change anything with ted, it's a good idea to look at the config file (see below) to check out all of the keyboard shortcuts! - You can use Ctrl+f for "find", but if you want to search for something across multiple files, you can do Ctrl+! (run shell command), then run `grep -n search_term *.py`, for example (on Windows, you will need to have cygwin or something in your PATH for this to work). The `-n` ensures that ted can jump to the results, just like jumping to build errors. ### Configuration At any time, you can check out all the keyboard shortcuts, and add your own, by opening your ted.cfg file. To do this, press Ctrl+Shift+p to open the command palette, and select "open-config". There are several sections to this config file: - `[core]` for core settings - `[keyboard]` for keyboard shortcuts - `[colors]` for colors - `[extensions]` for which file extensions should be mapped to which programming languages Comments begin with `#`, and all other lines are of the form `key = value`. You need to restart ted when you make a change to ted.cfg. The `core` section's settings should be pretty familiar (font size, etc.) or should have comments on the previous line explaining what they do. Keyboard shortcuts are of the form `key combo = action`, where `action` is an argument (number or string), followed by a command. The commands match the things in the command palette (Ctrl+Shift+p), but `:` is added to the beginning to make it clear it's a command. Colors are formatted like `#rgb`, `#rgba`, `#rrggbb` or `#rrggbbaa`, where r, g, b, and a are red, green, blue, and alpha (transparency/opacity). You can use a [color picker](https://www.google.com/search?q=color+picker) to help you out. The extensions section is fairly self-explanatory. To reset your ted configuration to the default settings, delete your ted.cfg file (`~/.local/share/ted/ted.cfg` on Linux, `C:\Users\\AppData\Local\ted\ted.cfg` on Windows) or move it somewhere else. ### IDE-like features If you are working in a compiled language, like C, you can press F4 to compile your code. The default is to run `make` in the current directory or one of its parents, depending on where `Makefile` is. On Windows, if `make.bat` exists, it will be run. If a `Cargo.toml` file exists in this directory or one of its parents, F4 will run `cargo build`. You can set the default build command in the `[core]` section of the config file. Jump to definition and autocompletion both depend on [ctags](https://github.com/universal-ctags/ctags). You can press Ctrl+T at any time to generate tags for all files in the current directory. Once you have a tags file, you can Ctrl+Click on an identifier to go to its definition. You can also press Ctrl+D to get a searchable list of all functions/types where you can select one to go to its definition. Press Ctrl+space to autocomplete. If there is only one possible completion from the tags file, it will be selected automatically. Otherwise, you'll get a popup showing all possible completions. You can press tab to select a completion (or click on it), and press Ctrl+space/Ctrl+shift+space to cycle between suggestions. Note that autocomplete just completes to stuff in the tags file, so it won't complete local variable names. Sorry. ## Building from source To install `ted` on Linux, you will need: - A C compiler - The SDL2 development libraries - wget, unzip (for downloading, extracting PCRE2) - cmake (for PCRE2) These can be installed on Ubuntu/Debian with: ``` sudo apt install gcc libsdl2-dev wget unzip cmake ``` Then run ``` wget https://ftp.pcre.org/pub/pcre/pcre2-10.36.zip sudo make install -j4 ``` On Windows (64-bit), first you will need to install Microsoft Visual Studio, then find and add vcvarsall.bat to your PATH. Next you will need the SDL2 VC development libraries: https://www.libsdl.org/download-2.0.php Extract the zip, copy SDL2-2.x.y into the ted directory, and rename it to SDL2. Also copy SDL2\lib\x64\SDL2.dll to the ted directory. You will also need PCRE2. Download it here: https://ftp.pcre.org/pub/pcre/pcre2-10.36.zip, unzip it, and put pcre2-10.36 in the same folder as ted. Then run `make.bat`. ## Version history
