---- femto text editor ----

based on nano.
|
|
|
|
|
|
|
|
|
|
draws graphics using ANSI control sequences.
|
|
|
|
|
|
|
|
|
|
this means the terminal must be in raw mode with echo
|
|
|
|
|
turned off. the `femto` wrapper script achieves this
|
|
|
|
|
using `sttry raw -echo` (it also restores the previous
|
|
|
|
|
terminal settings on exit).

---- WARNING ----
|
|
|
|
|
|
|
|
|
|
this is alpha quality software, still under active
|
|
|
|
|
development. although it seems to work fairly reliably
|
|
|
|
|
it has bugs!
|
|
|
|
|
|
|
|
|
|
please consider making backups (or using version control)
|
|
|
|
|
before femto this to modify important files.

|
|
---- getting started ----
|
|
|
|
|
|
2022-02-16 19:24:35 -05:00
|
|
|
you must provide a path to a file when starting femto:
|
|
|
|
|
|
|
|
|
|
./femto femto.tal
|
|
|
|
|
|
2022-03-23 23:03:20 -04:00
|
|
|
the femto launcher script makes many assumptions:
|
|
|
|
|
|
|
|
|
|
- uxnasm and uxncli are both in the PATH
|
|
|
|
|
- femto.tal is in the same directory as femto
|
|
|
|
|
- femto.rom should be (re)assembled every time
|
|
|
|
|
- femot.rom should be written in the same directory
|
|
|
|
|
|
|
|
|
|
once femto is not in active development a more robust
|
|
|
|
|
packaging process can be explored.

the femto status line contains a lot of information:

|
|
|
|
|
|
1. if the file has unsaved changes (**) or not (--)
|
|
|
|
|
2. the file name (e.g. "scratch.tal")
|
|
|
|
|
3. the number of bytes/lines (e.g. "[49 bytes, 8 lines]"
|
|
|
|
|
4. the x/y cursor position (e.g. "(1,8)" for col 1, row 8)
