[clach04]

Spun out of issue #35 for SciTE https://www.scintilla.org/SciTE.html

lua

https://github.com/clach04/puren_tonbo/blob/main/pt_scite.lua

Features

• ✔️ Can load and decrypt IF operating system environment variable PT_PASSWORD has be set to correct password.
• ✔️ Tested under Windows and Linux
• ✔️ save/write support working in main branch as of 2023-07 - old abandoned branch https://github.com/clach04/puren_tonbo/tree/issue52_scite_write not working under Window (untested under Linux), either bugged or buffered IO issue with Python (under Windows, seen with vim and workaround by using raw mode flag/setting, can NOT be done in code. Requires starting python interpreter with python -u or setting PYTHONUNBUFFERED=1)
• ✔️ GUI password prompt present in ptchper see tk support in Configurable password prompt #75 and enabled in lua plugin - see Windows GUI password prompt support #71
• ✔️ tested ensure failed load does not cause potential to accidentally save/overwrite failed that failed to load (e.g. assume worst case scenario where user says yes to overwrite). Detect failed load and block saves (if not already done). scite lua integration will allow user to accidentally overrwrite encrypted files with error messages #73

python

Idea: new issue for ptcipher to accept number of input bytes as command line option. If set, read that many bytes rather than looking for EOF. Windows buffered IO work around idea that need to be tested.

Research scite_OnOutputLine http://lua-users.org/wiki/SciteExtMan

note password passing issues (no set env var API, so would mean command line passing, or keyring). Could implement setenv() in c in a dll loaded into scite.

with:

• older (2019) Windows Scite Version 4.1.5
• Version 5.3.5 Scintilla:5.3.4 Lexilla:5.2.4 Mar 13 2023 14:19:28

I'm not seeing any evidence that popen is launching/working in write mode (w or wb). The attached script logs to a hard coded file and that file NEVER gets created.
