Aim: to change the Language view in the splash screen. When we grep Quick Setup, we can find that the relevant code that we are lookin for here is in the file
release/scripts/startup/bl_operators/wm.py
The relevant code is:
if bpy.app.build_options.international:
prefs = context.preferences
# fun-hacks - changing case
col.prop(prefs.view, "language", text="LANGUAGE")
col.separator()
We look at
dir(prefs.view) The result is:
[‘__doc__’, ‘__module__’, ‘__slots__’, ‘bl_rna’, ‘color_picker_type’, ‘factor_display_type’, ‘filebrowser_display_type’, ‘font_path_ui’, ‘font_path_ui_mono’, ‘gizmo_size’, ‘gizmo_size_navigate_v3d’, ‘header_align’, ‘language’, ‘lookdev_sphere_size’, ‘mini_axis_brightness’, ‘mini_axis_size’, ‘mini_axis_type’, ‘open_sublevel_delay’, ‘open_toplevel_delay’, ‘pie_animation_timeout’, ‘pie_initial_timeout’, ‘pie_menu_confirm’, ‘pie_menu_radius’, ‘pie_menu_threshold’, ‘pie_tap_timeout’, ‘render_display_type’, ‘rna_type’, ‘rotation_angle’, ‘show_addons_enabled_only’, ‘show_column_layout’, ‘show_developer_ui’, ‘show_gizmo’, ‘show_navigate_ui’, ‘show_object_info’, ‘show_playback_fps’, ‘show_splash’, ‘show_statusbar_memory’, ‘show_statusbar_stats’, ‘show_statusbar_version’, ‘show_statusbar_vram’, ‘show_tooltips’, ‘show_tooltips_python’, ‘show_view_name’, ‘smooth_view’, ‘text_hinting’, ‘timecode_style’, ‘ui_line_width’, ‘ui_scale’, ‘use_directional_menus’, ‘use_mouse_over_open’, ‘use_save_prompt’, ‘use_text_antialiasing’, ‘use_translate_interface’, ‘use_translate_new_dataname’, ‘use_translate_tooltips’, ‘use_weight_color_range’, ‘view2d_grid_spacing_min’, ‘view_frame_keyframes’, ‘view_frame_seconds’, ‘view_frame_type’, ‘weight_color_range’]
Here we find the ‘langugage’ attribute. We can set it’s value. We need to find the code corresponding to different languages available in Blender. We do another grep. We find the following file:
release/datafiles/locale/languages
The file looks like this:
0:Complete:
0:Automatic (Automatic):DEFAULT
1:English (English):en_US
9:Spanish (Español):es
2:Japanese (日本語):ja_JP
47:Slovak (Slovenčina):sk_SK
41:Vietnamese (tiếng Việt):vi_VN
13:Simplified Chinese (简体中文):zh_CN
Now let us change the language back to Japanese. The code is ja_JP. We set the language as:
context.preferences.view.language="ja_JP" Before we test it, we also make the value of following attribute is se to True, otherwise only part of some descriptions will be translated.
context.preferences.view.use_translate_interface=True
The final result is:
I started messing with blender source code. First compiled blender source following the procedure from blender website. When you start blender you see the following screen.
The small window in the middle is called the splash window. I wanted to change case of the names in the first column “language”, “Shortcuts” etc. to capitals. When I searched for the words like “Shortcuts” using grep:
grep -Rw "Shortcuts" .
I found out that they are in the file release/scripts/startup/bl_operators/wm.py . I looked through the file and found the place. There is a class called WM_MT_splash_quick_setup. I hacked the code there.
layout.label(text="Quick Setup".upper())
sub = col.column(heading="Shortcuts".upper())
col.row().prop(kc_prefs, "select_mouse", text="Select With".upper(), expand=True)
col.row().prop(kc_prefs, "spacebar_action", text="Spacebar".upper())
sub = col.column(heading="Theme".upper())
But “language” took me some time figure out how to change its case. Here is the piece of code:
