The only documentation about debugging the redisplay of emacs I did find in
./etc/DEBUG
** Debugging Emacs Redisplay problems
The src/.gdbinit file defines many useful commands for dumping redisplay
related data structures in a terse and user-friendly format:
`ppt' prints value of PT, narrowing, and gap in current buffer.
`pit' dumps the current display iterator `it'.
`pwin' dumps the current window 'win'.
`prow' dumps the current glyph_row `row'.
`pg' dumps the current glyph `glyph'.
`pgi' dumps the next glyph.
`pgrow' dumps all glyphs in current glyph_row `row'.
`pcursor' dumps current output_cursor.
However, this tells me nothing about an efficient debugging of
redisplay_internal, and about display in general.
Could you suggest me something efficient, please?
Alin
