2015-07-31less: fix line number confusionRon Yorston
Much of the code refers to lines using indices into the flines array (which splits lines into portions that fit on the terminal). In some cases this is wrong and actual line numbers should be used: - when lines are being truncated rather than wrapped (-S flag) - when line numbers have been entered by the user Also fix a bug in numeric input and improve the display at EOF. function old new delta goto_lineno - 111 +111 cap_cur_fline - 101 +101 buffer_to_line - 56 +56 buffer_up 35 66 +31 less_main 2606 2615 +9 goto_match 125 127 +2 buffer_down 81 56 -25 buffer_line 64 - -64 ------------------------------------------------------------------------------ (add/remove: 3/1 grow/shrink: 3/1 up/down: 310/-89) Total: 221 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2015-07-31less: add a function to detect when display is at end of fileRon Yorston
Add a function to package the test that detects whether enough has been read from the file to allow a screenful to be displayed. Also use this to determine when to display '(END)' in the status line. The previous code was incomplete and didn't handle truncated lines (-S flag) properly. function old new delta at_end - 63 +63 status_print 111 109 -2 read_lines 819 764 -55 getch_nowait 319 264 -55 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 0/3 up/down: 63/-112) Total: -49 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2015-07-31less: rearrange detection of non-regular filesRon Yorston
Move the code to detect non-regular files to the point where the file is being opened. If num_lines == READING_FILE guarantees that the file is regular. Detect when a file becomes unreadable between it first being opened and the call to update_num_lines. Mark the file as being non-regular so we don't try that again. function old new delta reinitialize 197 245 +48 update_num_lines 159 127 -32 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 48/-32) Total: 16 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2015-07-21less: improvements to verbose status messagesRon Yorston
Make verbose status messages (-m/-M flags) behave more like the real `less` command: - fix display of line numbers so they're correct whether lines are being truncated (-S flag) or wrapped. - don't display total lines or percentage when lines are read from stdin: we don't have that information until we reach EOF. When we do reach EOF the additional information is displayed. - when lines are read from a file count the total number of lines so that we can display percentages. Counting lines is avoided until the information is actually needed. If the user pages to EOF the separate read pass can be avoided entirely.

2015-07-19less: correctly account for tabs when rewrapping linesRon Yorston
Lines are rewrapped when the terminal width changes or line numbers are enabled/disabled. The current calculation always adds eight to the line length for a tab whereas it should only add enough to move to the next tab stop. This doesn't affect the display of lines, which is handled elsewhere and gets tab stops right, but it does cause lines to be wrapped at the wrong position.

2015-07-19less: fix display of line numbersRon Yorston
Line numbers are displayed incorrectly on lines that have a search pattern highlighted. The problem can be fixed by moving the call to lineno_str in print_found above the while loop that alters the value of the line pointer.

Trying to access /dev/i2c/* on every error after opening /dev/i2c-* can mislead users who e.g. don't have root access. Instead of bailing-out with "permission denied" we currently print "no such file or directory". Fix it by trying open("/dev/i2c/%d") only if we got ENOENT. Upstream i2cdetect tries to get any info it can from /sys and /proc even when invoked by an unprivileged user, but we don't want to add unnecessary bloat.
