Please note that the package is relocatable to any prefix and the option prefix
affects only the place where the application is actually installed.
## Installing Prebuilt
Head over to [releases](https://github.com/lite-xl/lite-xl/releases) and download the version for your operating system.
### Linux
Unzip the file and `cd` into the `lite-xl` directory:
```sh
tar -xzf <file>
cd lite-xl
```
To run lite-xl without installing:
```sh
cd bin
./lite-xl
```
To install lite-xl copy files over into appropriate directories:
```sh
mkdir -p $HOME/.local/bin && cp bin/lite-xl $HOME/.local/bin
cp -r share $HOME/.local
```
If `$HOME/.local/bin` is not in PATH:
```sh
echo -e 'export PATH=$PATH:$HOME/.local/bin' >> $HOME/.bashrc
```
To get the icon to show up in app launcher:
```sh
xdg-desktop-menu forceupdate
```
You may need to logout and login again to see icon in app launcher.
To uninstall just run:
```sh
rm -f $HOME/.local/bin/lite-xl
rm -rf $HOME/.local/share/icons/hicolor/scalable/apps/lite-xl.svg \
$HOME/.local/share/applications/org.lite_xl.lite_xl.desktop \

This files document the changes done in Lite XL for each release.
### 2.0.2
Fix problem project directory when starting the application from Launcher on macOS.
Improved LogView. Entries can now be expanded and there is a context menu to copy the item's content.
Change the behavior of `ctrl+d` to add a multi-cursor selection to the next occurrence.
The old behavior to move the selection to the next occurrence is now done using the shortcut `ctrl+f3`.
Added a command to create a multi-cursor with all the occurrences of the current selection.
Activated with the shortcut `ctrl+shift+l`.
Fix problem when trying to close an unsaved new document.
No longer shows an error for the `-psn` argument passed to the application on macOS.
Fix `treeview:open-in-system` command on Windows.
Fix rename command to update name of document if opened.
Improve the find and replace dialog so that previously used expressions can be recalled
using "up" and "down" keys.
Build package script rewrite with many improvements.
Use bigger fonts by default.
Other minor improvements and fixes.
With many thanks to the contributors: @adamharrison, @takase1121, @Guldoman, @redtide, @Timofffee, @boppyt, @Jan200101.
### 2.0.1
Fix a few bugs and we mandate the mod-version 2 for plugins.
This means that users should ensure they have up-to-date plugins for Lite XL 2.0.
Here some details about the bug fixes:
- fix a bug that created a fatal error when using the command to change project folder or when closing all the active documents
- add a limit to avoid scaling fonts too much and fix a related invalid memory access for very small fonts
- fix focus problem with NagView when switching project directory
- fix error that prevented the verification of plugins versions
- fix error on X11 that caused a bug window event on exit
### 2.0
The 2.0 version of lite contains *breaking changes* to lite, in terms of how plugin settings are structured;

```
The function stbtt_BakeFontBitmap is used to write bitmap data into set->image->pixels (where set is a GlyphSet).
Note that set->image->pixels need data in RGB format. After stbtt_BakeFontBitmap call the bitmap data are converted into RGB.
With a single call many glyphs corresponding to a range of codepoints, all in a
single image.
## STB truetype font metrics
stbtt_ScaleForPixelHeight takes a float 'height' and returns height / (ascent - descent).
stbtt_ScaleForMappingEmToPixels take a float 'pixels' and returns pixels / unitsPerEm.
### Computing RenFont
When loading a font, in renderer.c, the font->height is determined as:
```c
int ascent, descent, linegap;
stbtt_GetFontVMetrics(&font->stbfont, &ascent, &descent, &linegap);
float scale = stbtt_ScaleForMappingEmToPixels(&font->stbfont, font->size);
font->height = (ascent - descent + linegap) * scale + 0.5;
```
so, mathematically
```c
font->height = (ascent - descent + linegap) * font->size / unitsPerEm + 0.5;
```
**TO DO**: find out for what font->height is actually used.
### Call to BakeFontBitmap
In the same file, renderer.c, to create the glyphset image it computes:
```c
// Using stbtt functions
float s = ScaleForMappingEmToPixels(1) / ScaleForPixelHeight(1);
```
so 's' is actually equal to (ascent - descent) / unitsPerEm.
Then BakeFontBitmap is called and `font->size * s` is used for the pixel_height argument.
So BakeFontBitmap gets
```c
pixel_height = (ascent - descent) * font->size / unitsPerEm;
```
In turns BakeFontBitmap passes pixel_height to ScaleForPixelHeight() and uses the
resulting 'scale' to scale the glyphs by passing it to MakeGlyphBitmap().
This is equal almost equal to font->height except the 0.5, the missing linegap calculation
and the fact that this latter is an integer instead of a float.
## AGG Font Engine
Calls
`FT_Init_FreeType` (initialize the library)
In `load_font()` method:
`FT_New_Face` or `FT_New_Memory_Face` (use `FT_Done_Face` when done)
`FT_Attach_File`
`FT_Select_Charmap`
In `update_char_size()` method:
`FT_Set_Char_Size` or `FT_Set_Pixel_Sizes`
In `prepare_glyph()` method:
`FT_Get_Char_Index`
`FT_Load_Glyph`
`FT_Render_Glyph` (if glyph_render_native_mono or native_gray8)
in `add_kerning()` method
`FT_Get_Kerning`
`FT_Done_FreeType` (end with library)
## Freetype2's metrics related function and structs
`FT_New_Face` return a `FT_Face` (a pointer) with font face information.
## AGG font engine's font size
The variable `m_height` is the size of the font muliplied by 64.
It will be used to set font size with:
- `FT_Set_Char_Size` if m_resolution is set (> 0)
- `FT_Set_Pixel_Sizes`, divided by 64, if m_resolution is not set (= 0)
The method height() returns m_height / 64;

/*
The lite_xl plugin API is quite simple. Any shared library can be a plugin file, so long
as it has an entrypoint that looks like the following, where xxxxx is the plugin name:
#include "lite_xl_plugin_api.h"
int lua_open_lite_xl_xxxxx(lua_State* L, void* XL) {
lite_xl_plugin_init(XL);
...
return 1;
}
In linux, to compile this file, you'd do: 'gcc -o xxxxx.so -shared xxxxx.c'. Simple!
Due to the way the API is structured, you *should not* link or include lua libraries.
This file was automatically generated by the below code. Do NOT MODIFY DIRECTLY.
