Python 3 and Python scripts plugin

Bill Winder

Python 3, Python scrips plugin

I would like to use python 3 in Npp, especially with the python Script plugin. I know how to run script in Py3, but I the plugin allows for transferring the contents of the editor to the script and output to the console.

Is there a Npp py3 version? Or can I configure the plugin?

Claudia Frank

@Bill-Winder

No, but you can use NppExec plugin instead.
Download and install and configure your run command like

python3 -u "$(FULL_CURRENT_PATH)"

$(FULL_CURRENT_PATH) gets automatically replaced with the correct path of the current
active and saved document.

Cheers
Claudia

Yes, thanks! Unfortunately, nppexec doesn’t seem to have access to npp items, such as the editor content. In order to manipulate editor content, one would have to save the tab, then modify the file, the reload. At least, that’s the only way to replicate editor.getText() function I have found.

Is it really that important to be able to execute unsaved Python code? What’s the point?

Claudia Frank

@Bill-Winder

you can use NppExecs sci_sendmsg to execute scintilla messages
but of course it isn’t that flexible as python script.

Maybe you can explain the exact use case?

Cheers

This could seem a bit … lazy, but I want to paste something from an Internet page into a tab and then transform it directly by clicking on a pythonscript button. I was trying to avoid the extra step of deciding on a name for the pasted text, saving it somewhere, then retrieving it with nppexec. But, yes, it’s a tweak.

And then it became: What!??? pythonscript can only use 2.7? Why?

Scott Sumner

@Bill-Winder

Okay…so copy text from anywhere and put it in a “new” tab. Then run a Pythonscript (via button, menu, keycombo) that acts upon the text in the document tab using the editor object commands Pythonscript provides. You don’t have to save the tab to a file to operate upon its text. Why involve nppexec at all?

And then it became: What!??? pythonscript can only use 2.7? Why?

Yea…so I don’t get this… Is there some huge advantage that Python3 would give this purpose (scripting) over 2.7? I certainly don’t see what that would be but I am looking forward to being enlightened.

Bill Winder

I will be pasting French text, with accented characters. After struggling with encoding for some time in 2.7 (writing and reading to Windows in utf-8, reading sometimes from ansi, the locale setting), I finally threw in the towel and moved to 3. The encoding waters are much calmer.

I can write
with open(tempHtml,“w”, encoding=“utf8”) as f:
f.write(message)

I’m sure something equivalent can be done in 2.7, but 3 handles unicode in a much simpler way. That turns out to be important if you are constantly going from ansi to utf-8 (with or without BOM!).

In short, like any language, or software version, once you have set up shop there, you don’t want to have to switch, n’est-ce pas? (The looooong reason is here: https://docs.python.org/3/howto/unicode.html)

Now, no more (or less): ‘ascii’ codec can’t encode character ‘\ua000’ in
position 0: ordinal not in range(128)

chcg

Latest version of https://sourceforge.net/projects/npppythonscript/files/ is from 2014-09-27 and python 3 was not so popular at that time.

Bill Winder

@chcg I wonder whether six would allow pyscript to transition to 3. …I have never used six, so I don’t know what I’m asking! (for the moment, npp is pretty restrictive: a 3 installation won’t allow pyscript to be installed…)

Hi, @scott-sumner, and All,

Here are three links, on that eternal question : Python 2.x or Python 3.x !

The first one is a very interesting article ! See also the comments. As for the third one, it seems more code-oriented.

Probably, you are already aware of all that stuff, but who knows ?

http://python-notes.curiousefficiency.org/en/latest/python3/questions_and_answers.html

https://wiki.python.org/moin/Python2orPython3

https://docs.python.org/3/whatsnew/3.0.html

I wish you good reading !

Cheers,

And I am enlightened…to your need… Yes, this is one area where Python3 is advantageous over Python2. Fortunately, for myself, I don’t encounter the unicode need very often. Back to the why of Python2 for the Pythonscript plugin, I believe that there were some issues with Scintilla interaction which necessitated (at the time) using Python2 byte-strings versus Python3 unicode strings. I’m sure you can read about all the details of the design decisions on the old Pythonscript Soucreforge forums if you’d like…

Discussion from a few years ago which discusses some of the hurdles switching from v2 to v3: https://sourceforge.net/p/npppythonscript/discussion/1188885/thread/cf066585/

Bill Winder

@dail Wow! Hairy!

I do encounter just that problem in my normal use of npp. I can paste in è or ã and it generally works fine. But when I open or paste in certain texts (like phonetic transcription from espeak), I get o~ where I should get õ. Npp interprets some accent encoding as two characters, not one (works fine here):

la diskysjˈɔ̃ fˈy syspɑ̃dˈy pɑ̃dˈɑ̃ lə ʁˈɔbʁ
mɛ bjɛ̃tˈoˈandʁuː styˈaʁ la ʁəpʁənˈɛ

I have found no way to fix it by shifting the encoding. (Jedit does the same thing…, but notepad does not.)

make sure that the font you use is capable of displaying needed symbols

@Claudia-Frank Thanks Claudia! – that fixed it, the moment I checked “enable global font”.

Thanks! (It’s been bugging me…for a long time…)

Here is one of possible ways to get the text from an unsaved file tab in NppExec to allow further processing of the text:

// temporary file name
set local tmpfile = $(SYS.TEMP)\text.txt
// current selection
sci_sendmsg SCI_GETSELECTIONSTART
set local selStart = $(MSG_RESULT)
sci_sendmsg SCI_GETSELECTIONEND
set local selEnd = $(MSG_RESULT)
// select all the text and save it
sci_sendmsg SCI_SELECTALL
sel_saveto "$(tmpfile)"
// restore the selection
sci_sendmsg SCI_SETSELECTIONSTART $(selStart)
sci_sendmsg SCI_SETSELECTIONEND $(selEnd)
// now it's time to process the tmpfile...

Vitaliy Dovgan

Here is more “advanced” version that avoids visible selection change:

// temporary file name
set local tmpfile = $(SYS.TEMP)\text.txt
// disable redrawing
sci_sendmsg 0x000B 0 // WM_SETREDRAW FALSE
// current selection
sci_sendmsg SCI_GETSELECTIONSTART
set local selStart = $(MSG_RESULT)
sci_sendmsg SCI_GETSELECTIONEND
set local selEnd = $(MSG_RESULT)
// select all the text and save it
sci_sendmsg SCI_SELECTALL
sel_saveto "$(tmpfile)"
// restore the selection
sci_sendmsg SCI_SETSELECTIONSTART $(selStart)
sci_sendmsg SCI_SETSELECTIONEND $(selEnd)
// enable redrawing
sci_sendmsg 0x000B 1 // WM_SETREDRAW TRUE
// now it's time to process the tmpfile...

Vitaliy Dovgan

NppExec v0.6 beta 1 will introduce new command TEXT_SAVETO and TEXT_LOADFROM that will work with the whole current text. Apart from that, these commands will be similar to SEL_SAVETO and SEL_LOADFROM.

Hello, @bill-winder, and All,

I’m quite late, but I had have to update my list of fonts and to do some tests, in Notepad++, first ;-))

So, Bill, here is below, a list of Unicode fonts which can, correctly, display your text example :

la diskysjˈɔ̃ fˈy syspɑ̃dˈy pɑ̃dˈɑ̃ lə ʁˈɔbʁ
mɛ bjɛ̃tˈoˈandʁuː styˈaʁ la ʁəpʁənˈɛ

The first table concerns Monospaced fonts, where all characters have the same width
The second table concerns Proportional fonts, with variable width

Notes :

The Unicode number of code-points, handled by the font, is located in the Glyphs column
The different fonts are sorted out by increasing number of their glyphs
The default regular weight, only, of each font, is listed. The other weights ( Bold, Italic… ) are absent of the tables, below
The Lucida Sans Unicode is certainly already installed on your configuation ( v5.00 or higher )
The Segoe UI family font is probably installed, too ( v5.28 or higher )
For the Ioveska and Ioveska Slab fonts, read very carefully the README.md part, scrolling downwards, because these fonts are highly configurable ! Refer to :

https://github.com/be5invis/Iosevka
