Re: [dev] [dmenu] support for input methods

Regarding the wrong cursor position problem: Changing the default monospace font (in config.h) to a Chinese font is a good workaround for now.

The problem is that drw.c implements a font fallback mechanism on its own, but _only when_ drawing characters. When calculating the width of a string, it always use the first font (drw->fonts[0]) and no fallback mechanism is active.

Some patch suggestions:

1. You can implement another font fallback mechanism for calculating the width of a UTF-8 string. This would result in a bigger drw_font_getexts_width() function.
2. You can combine the drawing of the string and of the cursor. That is, drw_text() optionally draws the cursor after a specified position (in characters). Because drw_text() keeps track of the position of the character that is just drawn, it would put the cursor at the correct position.

Hope it helps,

I can type something with fcitx but not chinese characters.

Where's your patch?

>Anyway, now I can at least type something in dmenu. Wrong cursor position is just a minor problem, since I hardly need any editing for what I type in. I guess it has something to do with calculating the width of a text, and it should be easy to fix.

It should have something to do with wcwidth, I am not very sure, you can
take a look in st's code.
