Eu percebi isso antes de terminar de postar: eu tinha aliased less
to less -r
para manter a cor, mas aparentemente isso estraga menos:
-r or --raw-control-chars
Causes "raw" control characters to be displayed. The default is to
display control characters using the caret notation; for example, a
control-A (octal 001) is displayed as "^A". Warning: when the -r
option is used, less cannot keep track of the actual appearance of the
screen (since this depends on how the screen responds to each type of
control character). Thus, various display problems may result, such
Eu removerei esse alias ou tentarei usar -R
, que só retém as seqüências de escape de cor ANSI e deve funcionar "na maioria dos casos".
Após algum tempo, less -R
funcionou exatamente como eu queria e não causou problemas de exibição.
-R or --RAW-CONTROL-CHARS
Like -r, but only ANSI "color" escape sequences are output in "raw"
form. Unlike -r, the screen appearance is maintained correctly in
most cases. ANSI "color" escape sequences are sequences of the form:
ESC [ ... m
where the "..." is zero or more color specification characters For the
purpose of keeping track of screen appearance, ANSI color escape
sequences are assumed to not move the cursor. You can make less think
that characters other than "m" can end ANSI color escape sequences by
setting the environment variable LESSANSIENDCHARS to the list of char‐
acters which can end a color escape sequence. And you can make less
think that characters other than the standard ones may appear between
the ESC and the m by setting the environment variable LESSANSIMIDCHARS
to the list of characters which can appear.
