# lite-hearted
|
||||
|
||||
lite-hearted is a small compatibility shim for the lite text editor that allows
|
||||
it to run in love2d. It is a quick-and-dirty experiment in embedding editing tools
|
||||
into a game engine, to allow for building smooth game development workflows. It's
|
||||
also literally a two-evening hack, so you will probably run into some rough edges!
|
||||
|
||||
You can run it simply by cloning this repo and running `love .`. Due to the
|
||||
limitations of love2d's sandboxed filesystem, you can only edit files that are in
|
||||
the project itself. Given the goals of this project, this should be fine.
|
||||
|
||||
Original README follows:

||||

|
||||
## Overview
|
||||
lite is a lightweight text editor written mostly in Lua — it aims to provide
|
||||
something practical, pretty, *small* and fast, implemented as simply as
|
||||
possible; easy to modify and extend, or to use without doing either.
|
||||
|
||||
## Customization
|
||||
Additional functionality can be added through plugins which are available from
|
||||
the [plugins repository](https://github.com/rxi/lite-plugins); additional color
|
||||
themes can be found in the [colors repository](https://github.com/rxi/lite-colors).
|
||||
The editor can be customized by making changes to the
|
||||
[user module](data/user/init.lua).
|
||||
|
||||
## Building
|
||||
You can build the project yourself on Linux using the provided `build.sh`
|
||||
script. Note that the project does not need to be rebuilt if you are only making
|
||||
changes to the Lua portion of the code.
|
||||
|
||||
## Contributing
|
||||
Any additional functionality that can be added through a plugin should be done
|
||||
so as a plugin, after which a pull request to the
|
||||
[plugins repository](https://github.com/rxi/lite-plugins) can be made. In hopes
|
||||
of remaining lightweight, pull requests adding additional functionality to the
|
||||
core will likely not be merged. Bug reports and bug fixes are welcome.

# lite
|
||||
|
||||
![screenshot](https://user-images.githubusercontent.com/3920290/81471642-6c165880-91ea-11ea-8cd1-fae7ae8f0bc4.png)
|
||||
|
||||
## Overview
|
||||
lite is a lightweight text editor written mostly in Lua — it aims to provide
|
||||
something practical, pretty, *small* and fast, implemented as simply as
|
||||
possible; easy to modify and extend, or to use without doing either.
|
||||
|
||||
|
||||
## Getting Started
|
||||
When lite is started it's typically opened with a *project directory* — this
|
||||
is the directory where your project's code and other data resides. The project
|
||||
directory is set once when lite is started and, for the duration of the
|
||||
session, cannot be changed.
|
||||
|
||||
To open lite with a specific project directory the directory name can be passed
|
||||
as a command-line argument *(`.` can be passed to use the current directory)* or
|
||||
the directory can be dragged onto either the lite executable or a running
|
||||
instance of lite.
|
||||
|
||||
The main way of opening files in lite is through the `core:find-file` command
|
||||
— this provides a fuzzy finder over all of the project's files and can be
|
||||
opened using the **`ctrl+p`** shortcut by default.
|
||||
|
||||
Commands can be run using keyboard shortcuts, or by using the `core:find-command`
|
||||
command bound to **`ctrl+shift+p`** by default. For example, pressing
|
||||
`ctrl+shift+p` and typing `newdoc` then pressing `return` would open a new
|
||||
document. The current keyboard shortcut for a command can be seen to the right
|
||||
of the command name on the command finder, thus to find the shortcut for a command
|
||||
`ctrl+shift+p` can be pressed and the command name typed.
|
||||
|
||||
|
||||
## User Module
|
||||
lite can be configured through use of the user module. The user module can be
|
||||
used for changing options in the config module, adding additional key bindings,
|
||||
loading custom color themes, modifying the style or changing any other part of
|
||||
lite to your personal preference.
|
||||
|
||||
The user module is loaded by lite when the application starts, after the plugins
|
||||
have been loaded.
|
||||
|
||||
The user module can be modified by running the `core:open-user-module` command
|
||||
or otherwise directly opening the `data/user/init.lua` file.
|
||||
|
||||
|
||||
## Project Module
|
||||
The project module is an optional module which is loaded from the current
|
||||
project's directory when lite is started. Project modules can be useful for
|
||||
things like adding custom commands for project-specific build systems, or
|
||||
loading project-specific plugins.
|
||||
|
||||
The project module is loaded by lite when the application starts, after both the
|
||||
plugins and user module have been loaded.
|
||||
|
||||
The project module can be edited by running the `core:open-project-module`
|
||||
command — if the module does not exist for the current project when the
|
||||
command is run it will be created.
|
||||
|
||||
|
||||
## Commands
|
||||
Commands in lite are used both through the command finder (`ctrl+shift+p`) and
|
||||
by lite's keyboard shortcut system. Commands consist of 3 components:
|
||||
* **Name** — The command name in the form of `namespace:action-name`, for
|
||||
example: `doc:select-all`
|
||||
* **Predicate** — A function that returns true if the command can be ran, for
|
||||
example, for any document commands the predicate checks whether the active
|
||||
view is a document
|
||||
* **Function** — The function which performs the command itself
|
||||
|
||||
Commands can be added using the `command.add` function provided by the
|
||||
`core.command` module:
|
||||
```lua
|
||||
local core = require "core"
|
||||
local command = require "core.command"
|
||||
|
||||
command.add("core.docview", {
|
||||
["doc:save"] = function()
|
||||
core.active_view.doc:save()
|
||||
core.log("Saved '%s', core.active_view.doc.filename)
|
||||
end
|
||||
})
|
||||
```
|
||||
|
||||
Commands can be performed programatically (eg. from another command or by your
|
||||
user module) by calling the `command.perform` function after requiring the
|
||||
`command` module:
|
||||
```lua
|
||||
local command = require "core.command"
|
||||
command.perform "core:quit"
|
||||
```
|
||||
|
||||
|
||||
## Keymap
|
||||
All keyboard shortcuts in lite are handled by the `core.keymap` module. A key
|
||||
binding in lite maps a "stroke" (eg. `ctrl+q`) to one or more commands (eg.
|
||||
`core:quit`). When the shortcut is pressed lite will iterate each command
|
||||
assigned to that key and run the *predicate function* for that command — if the
|
||||
predicate passes it stops iterating and runs the command.
|
||||
|
||||
An example of where this used is the default binding of the `tab` key:
|
||||
``` lua
|
||||
["tab"] = { "command:complete", "doc:indent" },
|
||||
```
|
||||
When tab is pressed the `command:complete` command is attempted which will only
|
||||
succeed if the command-input at the bottom of the window is active. Otherwise
|
||||
the `doc:indent` command is attempted which will only succeed if we have a
|
||||
document as our active view.
|
||||
|
||||
A new mapping can be added by your user module as follows:
|
||||
```lua
|
||||
local keymap = require "core.keymap"
|
||||
keymap.add { ["ctrl+q"] = "core:quit" }
|
||||
```
|
||||
|
||||
|
||||
## Plugins
|
||||
Plugins in lite are normal lua modules and are treated as such — no
|
||||
complicated plugin manager is provided, and, once a plugin is loaded, it is never
|
||||
expected be to have to unload itself.
|
||||
|
||||
To install a plugin simply drop it in the `data/plugins` directory — installed
|
||||
plugins will be automatically loaded when lite starts. To uninstall a plugin the
|
||||
plugin file can be deleted — any plugin (including those included with lite's
|
||||
default installation) can be deleted to remove its functionality.
|
||||
|
||||
If you want to load a plugin only under a certain circumstance (for example,
|
||||
only on a given project) the plugin can be placed somewhere other than the
|
||||
`data/plugins` directory so that it is not automatically loaded. The plugin can
|
||||
then be loaded manually as needed by using the `require` function.
|
||||
|
||||
Plugins can be downloaded from the [plugins repository](https://github.com/rxi/lite-plugins).
|
||||
|
||||
|
||||
## Color Themes
|
||||
Colors themes in lite are lua modules which overwrite the color fields of lite's
|
||||
`core.style` module. Color themes should be placed in the `data/user/colors`
|
||||
directory.
|
||||
|
||||
A color theme can be set by requiring it in your user module:
|
||||
```lua
|
||||
require "user.colors.winter"
|
||||
```
|
||||
|
||||
Color themes can be downloaded from the [color themes repository](https://github.com/rxi/lite-colors).

We assume that instructions are unsigned numbers.

All instructions have an opcode in the first 6 bits.

Instructions can have the following fields:

`A' : 8 bits
|
||||
`B' : 9 bits
|
||||
`C' : 9 bits
|
||||
'Ax' : 26 bits ('A', 'B', and 'C' together)
|
||||
`Bx' : 18 bits (`B' and `C' together)
|
||||
`sBx' : signed Bx
|
||||
|
||||
A signed argument is represented in excess K; that is, the number
|
||||
value is the unsigned value minus K. K is exactly the maximum value
|
||||
for that argument (so that -max is represented by 0, and +max is
|
||||
represented by 2*max), which is half the maximum for the corresponding
|
||||
unsigned argument.

Notes:

(*) In OP_CALL, if (B == 0) then B = top. If (C == 0), then `top' is

set to last_result+1, so next open instruction (OP_CALL, OP_RETURN,

|

(*) In OP_VARARG, if (B == 0) then use actual number of varargs and

set top (like in OP_CALL with C == 0).
|
||||
|
||||
(*) In OP_RETURN, if (B == 0) then return up to `top'.
