NVDAScripts

This repo gathers various scripts for NVDA screen reader that I have not (yet?) packaged as NVDA addon. This may include potential features in development, (to be included later in an addon), debug scripts, test scripts, etc. It also includes some configuration files.

Installation

  • For NVDA up to 2018.4.1, copy the script you want to install in the corresponding subfolder (appModules or globalPlugins) in the user config folder of NVDA.
  • For NVDA from 2019.1 onwards:
    • In the Advanced category of the settings dialog, check the "Enable loading custom code from Developer Scratchpad directory" option.
    • Press the "Open developer scratchpad directory" button
    • copy the script you want to install in the corresponding subfolder (appModules or globalPlugins) of the scratchpad folder.
    • Validate with "OK" in the settings dialog.

globalPlugins Scripts

globalPlugins/changeOutputDevice.py

This global plugin creates a command to cycle through the audio output devices.

globalPlugins/configDuringSayAll

This script allows to modify speech parameter while in SayAll without stopping SayAll. The commands affected by this feature are the synthesizer ring commands, the command to cycle through punctuation level and thetoggle to report or not CLDR.

globalPlugins/diffMaker.py

If you have Git installed on your computer, this script allows you to make a git diff between two lines and to get the result in a browsable message. Press NVDA+alt+d to display a menu allowing to choose a reference (first line) and to make the diff (second line). The diff can be done by word or by character.

Note: this script does not work correctly. On my computer, it works just after NVDA restart, but after some time of use, it produce an error. I need to restart NVDA to have it working again.

globalPlugins/findExtended.py

This script removes the dialog box that appears when no more occurrence is found during a search operation. Only a message is reported instead.

globalPlugins/langChangeRate.py

A quick and dirty script allowing to modify the speech rate when a language other than the default language is detected. To configure the modification factor, e.g. -40%, type in the console: config.conf['paramChangeUponLangChange']['rateChange'] = -40 Not tested with rate boost on.

globalPlugins/ocrPdf.py

This script allows to OCR an opened PDF in Adobe Reader with MS word. Before first use, open a PDF manually in MS Word. If you did not disable it before a warning dialog will appear with the following message: "Word will now convert your PDF to an editable Word document.  This may take a while.  The resulting Word document will be optimized to allow you to edit the text, so it might not look exactly like the original PDF, especially if the original file contained lots of graphics." Check the checkbox "Don't show this message again" and validate by clicking "OK". If you want to restore Word's original behaviour with this dialog appearing, opan the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Word\Options And delete the delete the DisableConvertPdfWarning value or set it to 0. Work is in course to support the conversion from a selected file in Windows Explorer but this is not yet functional.

globalPlugins/romanNumbers.py

This script adapts the CamelCase word split rule to exclude the cases of ordinal roman numbers used in French.

globalPlugins/visualHighlighterToggler.py

This module adds script (unassigned by default) to toggle Visual Highlighter.

appModules scripts

appModules/matlab.py

A script to issue some commands in Matlab console by just pressing a keystroke. E.g. press F5 to issue "dbcont" command. The lib folder contains a dependancy. Thus, it has also to be copied in the scratchpad folder. The file gcep.m should be copied in a location available in the matlab PATH. This file contains an hard-coded string to open files in your editor; you should modify it for your needs.

appModules/notepad.py

A plugin to have the current line read when pressing enter to send the caret to the next line. This plugin aims to answer the need related to communication between a mute person and a blind person.

visionEnhancementProviders

colorEnhancer.py

A prototype in alpha stage to play with vision enhancement providers and Magnification API. This provider allows to customize the screen color transformation.

Configuration files

symbols-fr.dic

My French symbol configuration file. Specifically it includes the following extra character description:

  • additional latin characters with diacritics
  • IPA characters
  • greek characters with diacritics (the greek characters without diacritic are already included in NVDA's French symbols.dic)
  • cyrillic characters
  • a few musical symbols

Removed scripts

Debug and test scripts

The following debug and test scripts have been included in the NVDA Dev & Test Toolbox addon.

  • globalPlugins/beepError.py
  • globalPlugins/debugHelpMode.py
  • globalPlugins/debugTool.py
  • globalPlugins/windowutil.py

globalPlugins/startupOptionWorkaround.py

This script has been packaged as an add-on: Startup option workaround add-on that is itself deprecated.

With Windows 10 1903 update, NVDA may start after logon even when this is disabled in General settings panel (cf. #9528). This script does not fix the issue. However, as a work-around, it unloads NVDA just after startup in the case it should not have started up at all. Of course, when #9528 is fixed in NVDA (or in Windows), this script is useless and should be removed.

globalPlugins/autoLangSwitch.py

This feature has been integrated in NVDA 2022.2 (see issue #10253).

This script allows to cycles through speech automatic language detection modes off, language only and language+dialect with NVDA+shift+L shortcut.
