ls: fix alignment when month names have varying widths

2009-04-02T23:34:11Z

Reported by Samuel Thibault and Stéphane Raimbault, as the glibc fr_FR locale has recently changed to use the official but variable width abbreviated month names. Other glibc locales also have variable widths. http://sourceware.org/ml/libc-locales/2008-q1/msg00035.html http://sourceware.org/bugzilla/show_bug.cgi?id=9859 * NEWS: Mention the fix * gl/lib/mbsalign.c: A new module to align and truncate a string in a specified number of screen cells, while handling multi-byte characters appropriately. * gl/lib/mbsalign.h: Ditto * gl/modules/mbsalign: Ditto * bootstrap.conf: Reference the new module * src/ls.c (abmon_init): New function, precompute the abbreviated months aligned left in a minimum width column <= 5 screen cells. (align_nstrftime): New function, replace the first %b in the format specification to strftime with the precomputed month string. Note using the cached month strings speeds up `ls -lU` by around 17% on glibc-2.7-2 on linux at least. Also if we implement this function using heap storage rather than automatic storage, and use snprintf instead of strcpy, ls will slow down by 2% and 1% respectively (i.e. a net gain of 14% rather than 17%). * tests/ls/abmon-align: A new test to test ls alignment for various formats and locales * tests/Makefile.am: Reference the new test

ls: make it possible to disable coloring of hard links

2009-03-24T16:11:00Z

* src/ls.c (print_color_indicator): Don't color hard links if disabled (when there is an empty hl= in the LS_COLORS environment variable). * tests/ls/hardlink: Add test case for disabled hard link highlighting. * NEWS: Mention the change.

maint: avoid new unused-macro warnings from gcc

* src/ls.c (ASSERT_MATCHING_DEV_INO): Comment-out unused definition, to match commented-out use. * src/install.c (INITIAL_HASH_MODULE, INITIAL_ENTRY_TAB_SIZE): (READ_SIZE): Remove definitions of unused macros. * src/mv.c (INITIAL_HASH_MODULE, INITIAL_ENTRY_TAB_SIZE): Likewise. * src/dd.c (max): Likewise. * src/expand.c (OUTPUT_BLOCK): Likewise. * src/csplit.c (ALLOC_SIZE): Likewise. * src/pr.c (NULLCOL): Likewise. * src/ptx.c (Sword): Likewise. * src/unexpand.c (OUTPUT_BLOCK): Likewise. * src/factor.c (NDEBUG): Likewise.

doc: ls: clarify description of -s

2009-02-20T18:32:02Z

* src/ls.c (usage): Make the description of -s mention "allocated size", so that it's less likely to be confused with an apparent byte-count. Suggested by Vito Caputo.

ls: clean up after wrapped+colored file names with clear-to-EOL

2009-02-10T13:47:39Z

This change addresses a relatively unusual case: ls --color, with a highlighted name being printed initially in the last row of a terminal emulator (possibly followed by other lines of output) such that it is wrapped onto the following line, as the terminal emulator scrolls the output. That would cause the entire following line to be highlighted, even if the name happened to use only one position. The least-invasive patch would have made colorized output larger for all uses. The approach taken below is more invasive, but limits the increase in overhead to only those lines that are expected to wrap. * src/ls.c (enum indicator_no): Add C_CLR_TO_EOL. (indicator_name): Add "cl". (color_indicator): Add default escape codes for "cl". (print_long_format): Propagate width to print_name_with_quoting. (print_name_with_quoting): Print new C_CLR_TO_EOL string if needed. Return the width of what we're printing. (print_file_name_and_frills): Propagate width. (print_type_indicator): Return bool (aka width). (print_many_per_line): Pass column position to print_* function. (print_current_files): Likewise. (print_horizontal): Likewise. (print_with_commas): Likewise. * src/dircolors.c (slack_codes): Add "CLRTOEOL". (ls_codes): Add "cl". * tests/ls/color-clear-to-eol: New file. Test for this fix. * tests/Makefile.am (TESTS): Add ls/color-clear-to-eol. * THANKS: Update. Reported by Alexander V. Lukyanov. See thread for details: http://thread.gmane.org/gmane.linux.kernel/740021/focus=14824 Thanks to Jan Engelhardt for helping me reproduce the problem. Demonstrate with this in an 80-column xterm: seq 200 # to start in the "bottom" row touch zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz.foo env LS_COLORS='*.foo=0;31;42' ls -og --color=always Before the fix, you'd see something like this: (where the file name is printed in red on a green background, and each "=" denotes a space on a green background) ... -rw-r--r-- 1 0 Feb 5 11:31 zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzz.foo=================================================== After the patch, the trailing green spaces are gone: -rw-r--r-- 1 0 Feb 5 11:31 zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzz.foo
