Font choice for Status bar and Alt status bar?

[Sonnenfee]

Before changing to KOReader again I used CoolReader on my devices.

One thing I miss in KOReader is using my reading font also for Status bar and Alt status bar.

I would really appreciate and love if this could be developed also for KOReader

If you don't mind changing the source code whenever you update koreader,
for the alt status bar you can change the value of header_font in

frontend/document/credocument.lua

For the regular status bar, there are fonts in

frontend/ui/font.lua

you can change. (I change a few fonts, so I don't know exactly which ones affect what, but you probably want header font "hfont" and the various title fonts).

Thank you for answering.

We are talking about two different things. You mean the font size and I the font/type.

I'm reading my books with the font/type "Keep calm" and it would be cool if there were a possibility to chose this font/type also for the Alt Status Bar and Status Bar. Then all have the same look, the letters in the book and the letters in Alt Status bar and Status Bar. Now this is different and there is no option, to chose any other font/type.

That's the font I'm using:

https://www.dafont.com/de/search.php?q=keep+calm

and would be nice to have it also for the Alt Status Bar and Status Bar.

Nope, you're talking about the same thing and jberd is right:

He pointed you to both family and size of fonts used across the entire UI (including the statusbar)

He stated that the top/alternative status bar is a special snowflake handled elsewhere, which is also right.

And most importantly: he suggested that the only way to change fonts right now is to change stuff in the source code (Stuff that you will need to change again after each update)

Isn't there a settings/data/cr3.ini you can edit for the alt statusbar that won't be overwritten by updates? Or is that no longer a thing.

Specifically, that file would take settings like these:

crengine.page.header.font.color=0xFF000000
crengine.page.header.font.face=Noto Sans
crengine.page.header.font.size=10

Thanks for the clarification and explanation, @pazos.

I will take a look when I getting time for it.
KOReader is always evolving and becomes new functionality so I'm more likely prefering new releases without doing the work of changing it manually every time.

Maybe someday will be the possibility to select and change the font for the Alt status bar and Status bar directly in the KOReader menu

Thanks to jberd for giving me the right way and Frenzie for answering.

i created a couple level 2 user patches (create patches named "2-yourpatchname.lua") that hard code my desired user font for the statusbar and alt-statusbar. Like you, i wanted my reading font to also populate the header and footer portions of the page. (You will have to edit the patches and substitute your own font choice).

For the statusbar..

local Font = require("ui/font")
for k, v in pairs(Font.fontmap) do
	if k == "ffont" then
		Font.fontmap[k] = "yourfont-regular.ttf"
	elseif k == "smallffont" then
		Font.fontmap[k] = "yourfont-regular.ttf"
	elseif k == "largeffont" then
		Font.fontmap[k] = "yourfont-regular.ttf"
	end
end

A somewhat longer patch for the alt-statusbar required..

local Screen = require("device").screen
local Event = require("ui/event")
local ReaderFont = require("apps/reader/modules/readerfont")
ReaderFont.onReadSettings = function(self)
	self.font_face = "yourfont"  -- your reading font (text body)
	self.ui.document:setFontFace(self.font_face)
	self.header_font_face = "yourfont"  -- your alt-statusbar font
	self.ui.document:setHeaderFont(self.header_font_face)
	self.ui.document:setFontSize(Screen:scaleBySize(self.configurable.font_size))
	self.ui.document:setFontBaseWeight(self.configurable.font_base_weight)
	self.ui.document:setFontHinting(self.configurable.font_hinting)
	self.ui.document:setFontKerning(self.configurable.font_kerning)
	self.ui.document:setWordSpacing(self.configurable.word_spacing)
	self.ui.document:setWordExpansion(self.configurable.word_expansion)
	self.ui.document:setCJKWidthScaling(self.configurable.cjk_width_scaling)
	self.ui.document:setInterlineSpacePercent(self.configurable.line_spacing)
	self.ui.document:setGammaIndex(self.configurable.font_gamma)
	table.insert(self.ui.postInitCallback, function()
		self.ui:handleEvent(Event:new("UpdatePos"))
	end)
end

This patch is a bit hacky of the function it replaces, omitting self:updateFontFamilyFonts().

You can find my dotfiles here,

i am not sure if there are any negative side effects -- other parts of KOReader that may be impacted by these overrides -- but they work for me.

Since 02.2024 release it will be enough to set "header_font" in settings.reader.lua to change the font face in alt status bar.

Thanks for confirming this. My original post above actually had this simple user patch..

local CreDocument = require("document/credocument")
CreDocument.header_font = "yourfont"

and for some reason it stopped working (across all my devices.. Kobo, Kindle, Android). Drove me nuts, so i editted the post with my old hacky solution above.

Long story short, i replaced the hacky user patch with the above and it is working now. Again. Have no idea what i did in the interim to have the NotoSans font reappear in the alt-statusbar.

PLEASE correct my above user patch if it is not properly referencing the "header_font" in "settings.reader.lua". (i had come across a G_reader_settings reference to it but could not decipher its construction and relationship to luasettings).

settings.reader.lua is a file in your koreader directory that contains all of your settings.

For me this will be a cool thing and will love it

@hius07 or @Frenzie or to the person which made it possible and did the work

[Frenzie]

Probably @hius07. It may well have been a few years since I touched any of that particular code.

i found a couple of books in my rotation that did not exhibit the font setting for the alt-statusbar.

Not sure what the cause or reason (something recorded in the .sdr?).

The fix for this is to go into top menu..

document -> document settings -> reset document settings to default

..after which, the expected alt-statusbar font is displayed.

Ah.. i missed that file working from the git source and not the device itself.

Checking my Kobo settings.reader.lua, no "header_font" field existed. There were several other "cre_header_..." elements.

The patch i used on the "credocument.lua" appears to work. (i'm uncertain what the lua syntax would be for a user patch to append "cre_header_font" to settings.reader).

Not a user patch, you just edit it (after saving a backup).
