DESCRIPTION

MENUS
- FILE MENUS
- Open Open a new file in a net tab.
You can open one or more files from the resulting file selection dialog. - Close Close the current tab and its file.
- Quit close all files and and exit peless.
- EDIT MENUS
- Font Choose a new font with which to display all files.
When peless exits the last font used becomes the default font for future invocations of peless. - Find Find a text string or regular expression in the displayed text
file. This dialog can control multiple features for the search.
Regular expression type can be one of the following:
literal, normal, basic, or extended.
literal searches for a literal text string not a regular expression: This is not regular expression searching at all, but simply search for a literal text string. (Searching for dummies.) All characters in the string are treated as literals, there are no special characters or escape sequences.Normal regular expressions: Specifies that the grammar recognized by the regular expression engine uses its normal semantics: that is the same as that given in the ECMA-262, ECMAScript Language Specification, Chapter 15 part 10, RegExp (Regular Expression) Objects (FWD.1). said to be the same as the way perl searches.Basic specifies that the grammar recognized by the regular expression engine is the same as that used by POSIX basic regular expressions in IEEE Std 1003.1-2001, Portable Operating System Interface (POSIX ), Base Definitions and Headers, Section 9, Regular Expressions (FWD.1). said to be the way sed searches.Extended Specifies that the grammar recognized by the regular expression engine is the same as that used by POSIX extended regular expressions in IEEE Std 1003.1-2001, Portable Operating System Interface (POSIX ), Base Definitions and Headers, Section 9, Regular Expressions (FWD.1). Said to be the way egrep searches.When the require exact case match checkbox is checked, the searched for string must match the case of the target exactly or no match will be found. When unchecked, the case of the searched for string does not matter.When the reverse search direction checkbox is checked, the search will procede in the reverse direction, that is from the current position toward the beginning of the file. - Find next
- Find the same text string or the same regular expression again in the same displayed text file.
REQUIREMENTS
Requires the boost library, gtkmm2, gconfmm2.
DIAGNOSTICS
The following error messages may be displayed by error dialogs:
basic_filebuf::underflow error reading the file
Invalid byte sequence in conversion input
basic_filebuf::underflow error reading the file
Error compiling regular exception:
Regular expresion search failed, continue search from beginning of
buffer.
Regular expresion search failed, continue search from end of buffer.
Regular expression search failure.
BUGS
The regular expresion searching is done only with the "classic" locale,
not necessarily the locale that the user is using.
