Bugs in less-352

This is a list of the known bugs in less-352.

#101

Using the -s flag can put "~" lines before the beginning of the file.

#104

Using the -s flag on a file with trailing blank lines, type the "G" command. The prompt may say "99%" instead of "100%".

#130

Command "F" doesn't work if the file shrinks in size.

#138

On Solaris, searching for "a[1,2]" matches "a4".

#152

On a Solaris cmdtool, slow pipes get stalled and never show any data.

#174

Cannot search for a string which follows a null byte ('\0').

#185

On some terminals, arrow keys don't work when you set -X.

#192

In certain cases, when built with a non-POSIX regular expression library, if search highlighting is enabled and a search pattern begins with a ^, more text than the matching string may be highlighted.

#193

On some systems which use setlocale() and the LC_* environment variables, less treats some binary files as ordinary, non-binary files. You can workaround this problem by setting the environment variable LESSCHARSET to "ascii" (or whatever character set is appropriate).

#200

On Windows NT, if the screen buffer is larger than the displayed window size, lines can "leak" into the offscreen part of the buffer. (If any Windows expert can help me with this one, I'd appreciate it.)

#201

The DOS version compiled under DJGPP cannot open long (non-DOS) filenames when run on Windows-NT.

#203

The Windows version compiled under Microsoft Visual C++ sometimes highlights incorrectly when a highlighted line is longer than the screen width. (If any Windows expert can help me with this one, I'd appreciate it.)

#211

You cannot open a file that starts or ends with a double quote.

#226

There is a race condition when less is in a pipeline and a signal is sent to all processes in the pipeline. In this case, less and another process may try to change terminal attributes at the same time.

#229

Cannot build the SECURE version of less.

#230

The Makefile generated by the configure script tries to link with -lcurses on HP-UX 11.00. Apparently due to bugs in the HP-UX curses library, this version doesn't run correctly. Manually changing the Makefile to use -ltermcap builds a version that works.

Feature enhancement requests

This is a list of enhancement requests.

#102

Allow -o to work on non-pipe input (ordinary files).

#112

If the cursor is not at the bottom of the screen, begin display at the current cursor position; don't move to bottom line before displaying the first screen.

#162

Make compliant with POSIX specification for "more".

#184

Add a "bookmark" capability; that is, allow file marks to be saved on exit and restored at the next invocation of less on the same file.

#212

less -N with output redirected to a file or pipe should still output line numbers.

#220

Support multiple fixed tab stop positions.

#221

Distribute a sample LESSOPEN filter. Distribute a LESSOPEN filter that does C syntax highlighting.

#223

Add a command that does dynamic grep-like filtering of the input file.

#224

Make control-L in the input file act like a page break.
