Python 3 and Python scripts plugin

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 ?

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

I wish you good reading !

Cheers,

I am looking forward to being enlightened

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…

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

@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

@Vitaliy-Dovgan Thanks! Good work around. There must be somewhere direct access to an unsaved tab, because I can close npp with an unsaved tab and when I reopen, it is there. So the unsaved tab is actually saved somewhere. Curious!

Yes, saved under a “Backup” folder by default. I just made 5 “new files” and they were created in this folder with the following names:

new 1@2018-02-19_155611
new 2@2018-02-19_155613
new 3@2018-02-19_155613
new 4@2018-02-19_155615
new 5@2018-02-19_155618

@guy038 Very cool! I just chose fonts at random until things looked right. Useful description, which will serve elsewhere also – same issue in Jedit. (Though I use Jedit less and less - npp has everything I need and is very fast.)

Bill Winder

@Scott-Sumner and they are numbered! Perfect. Which essentially solves my problem.

I hope! There is one further step. I will have to capture the name of the active tab and give it to NPPEXec.

But that should be possible through the sci_sendmessage function (will look into that), since this is possible:

sci_sendmsg SCI_GETSELECTIONSTART
set local selStart = $(MSG_RESULT)
