Hi All,
I have a function that loops through an XML file line by line and spits it the content out to a new file (sometimes certain lines need changing). This all works fine, however the formatting of the original XML is not kept.

I just ran an application that crashed... but before it did, it managed to set readline echo off, and probably a bunch of other settings.
Is there any way I can just tell my shell to re-initialize? To get back to whatever state existed before my shell got messed up by this evil program? (2 Replies)

yacc
YACC(1) General Commands Manual YACC(1)NAME
yacc - an LALR(1) parser generator
SYNOPSIS
yacc [ -dlrtv ] [ -b file_prefix ] [ -p symbol_prefix ] filename
DESCRIPTION
Yacc reads the grammar specification in the file filename and generates an LR(1) parser for it. The parsers consist of a set of LALR(1)
parsing tables and a driver routine written in the C programming language. Yacc normally writes the parse tables and the driver routine to
the file y.tab.c.
The following options are available:
-b file_prefix
The -b option changes the prefix prepended to the output file names to the string denoted by file_prefix. The default prefix
is the character y.
-d The -d option causes the header file y.tab.h to be written.
-l If the -l option is not specified, yacc will insert #line directives in the generated code. The #line directives let the C
compiler relate errors in the generated code to the user's original code. If the -l option is specified, yacc will not
insert the #line directives. #line directives specified by the user will be retained.
-p symbol_prefix
The -p option changes the prefix prepended to yacc-generated symbols to the string denoted by symbol_prefix. The default
prefix is the string yy.
-r The -r option causes yacc to produce separate files for code and tables. The code file is named y.code.c, and the tables
file is named y.tab.c.
-t The -t option changes the preprocessor directives generated by yacc so that debugging statements will be incorporated in the
compiled code.
-v The -v option causes a human-readable description of the generated parser to be written to the file y.output.
If the environment variable TMPDIR is set, the string denoted by TMPDIR will be used as the name of the directory where the temporary files
are created.
FILES
y.code.c
y.tab.c
y.tab.h
y.output
/tmp/yacc.aXXXXXX
/tmp/yacc.tXXXXXX
/tmp/yacc.uXXXXXX
DIAGNOSTICS
If there are rules that are never reduced, the number of such rules is reported on standard error. If there are any LALR(1) conflicts, the
number of conflicts is reported on standard error.
