Self-modifiable text editor implemented in Janet.
Freja is in beta. It's stable, and crashes are rare. Files are backed up on opening / closing, so it's hard to lose work.
Some functions are missing (autocomplete when opening files, changing between files quickly). There is currently an issue on Windows that makes it hard to evaluate code inside Freja.
Currently mostly usable for Janet, no other language specific tooling. It works as a regular text editor, so I write C in Freja.

- on newer versions of janet, you need to install jpm separately:
- libglfw3-dev
- (X)ubuntu:
sudo apt-get install libglfw3-dev
- (X)ubuntu:
- Raylib dependencies -- https://github.com/raysan5/raylib#installing-and-building-raylib-on-multiple-platforms
[sudo] jpm install https://github.com/Saikyun/freja
If you get an old version, try running [sudo] jpm clear-cache before re-running the above command.
git clone https://github.com/Saikyun/freja
cd freja
sudo jpm deps
jpm build
janet freja/main.janet
NOTE: When running freja from source, you must start it from the project directory.
If you start it from another directory, you will get errors like:
could not open file fonts/MplusCodeLatin60-Medium.otf
If you want to run freja anywhere, it's better to jpm install it, or jpm build it.
If you want to use PREFIX as to not litter system wide libs, check out sogaiu's post about it.
# | is the cursor

# hit Ctrl+Enter

This can be very useful when trying to run example code in files,
or just play around with the code.
The main way to use this is to open a file, hit Ctrl+L
which will make Freja look at the environment of that file.
Successive calls to Ctrl+Enter and Ctrl+L will then act in that environment.
Whenever you run hit Ctrl+L you run freja/file_handling/save-and-dofile.
This saves the file, and then runs the file using a variant of janet's dofile.
This leads to a new environment table being created (using make-env).
This environment table is then used whenever you hit Ctrl+Enter,
which calls freja/input/eval-it.
eval-it will run the code to the left of the cursor, specifically,
a symbol, keyword, string, number, struct, table, tuple (including a function call), or array.
Thanks to sogaiu and rhine for initial testing. <3
