tex2mail - TeX to ascii math prettyprinter
SYNOPSIS
tex2mail [-linelength= length] [-maxdef= number] [-debug= number] [-by_par= number] [-TeX] [-ragged] [-noindent]
DESCRIPTION
Filter converting TeX or LaTeX math formulae to ASCII art. tex2mail is used by the PARI-GP calculator for output method external pret-
typrint . Under gp, prettyprint mode can be set by default(output, 3) (or o3). By default, this switches gp main output to TeX format,
filtered by
tex2mail -TeX -noindent -ragged -by_par
Flags passed to tex2mail can be modified via the prettyprinter default in gp.
OPTIONS
The following command line options are available:
-linelength=length
Wrap text at this column.
-maxdef=number
definition loops: croak if more than maxdef substitutions in a given paragraph.
-debug=debuglevel
output debugging messages.
-by_par
Expect each paragraph to be terminated by *exactly* 2 "
", and do not print an extra "
" between paragraphs.
-TeX Assume input formulae are in plain TeX format.
-ragged
leave right ragged.
-noindent
assume
oindent everywhere.
BUGS
% at the end of a line followed by
is recognized as end of paragraph

GPHELP(1) General Commands Manual GPHELP(1)NAME
gphelp - GP-PARI online help script
SYNOPSIS
gphelp [-to_pod file] [-raw] [-detex] [-k] [-ch c1] [-cb c2] [-cu c3] [keyword [ @{1,2,3,4,5} ]] [tutorial] [refcard]...
DESCRIPTION
Invokes the PARI-GP online help script. By default, keyword is understood as a section heading (a GP function name), and gphelp looks for
it in Chapter 3 of PARI User's Manual. If it is found, the corresponding section is copied to a temporary file in /tmp (or $GPTMPDIR), TeX
is run then the corresponding section is displayed in a separate window, using xdvi (or $GPXDVI).
If more than one keyword is given on a single command line, the outputs are concatenated. If keyword is omitted, open the whole manual
users.dvi. The keywords tutorial and refcard open the GP tutorial and reference card respectively.
GP defaults, help sections (1 to 11) as well as some keywords (readline, bnf, ell, all operators...) are recognized and treated in a spe-
cial way to make sure they match a section heading. For instance && is translated to Comparison and boolean operators which isn't that
obvious to guess. Make sure to enclose keyword between quotes if it contains dangerous characters (e.g spaces). For instance, you need to
type
gphelp -k "elliptic curves"
and not
gphelp -k elliptic curves
which would look for "elliptic" then for "curves" and output e.g. ploth among the relevant sections.
FULL SEARCH : @ MARKERS
The pattern @x (where x is a chapter number between 1 and 5) at the end of keyword conducts the search in the corresponding chapter instead
of the default Chapter 3. If the number is omitted, search the whole manual. For instance
gphelp -k gerepile@4
will look for gerepile in Chapter 4 of users manual.
gphelp -k gerepile@
will search the whole manual. All chapters of the manual (usersch[1-5].tex) are assumed to be in $GPDOCDIR (defaultvaluesetby Configure).
You are allowed to gzip (or compress) them, this won't affect the search.
OPTIONS
The following command line options are available:
-cb, -color_bold c2
color used for bold. See -color_help.
-ch, -color_help c1
color (between 1 and 16) used for general printing. Only significant in detex mode.
-cu, -color_underline c3
color used for underline. See -color_help.
-detex Use detex mode. The TeX file is converted to readable screen output that is directly written to the terminal; don't use tex or xdvi.
-k Switch to apropos mode. Only write to standard output the list of section headings in manual which contain keyword.
You can then choose an element in the list and use it as argument for gphelp (surround it by quotes if it includes spaces), possibly
followed by a trailing @ marker (see above).
-raw use internal format for output (using @x markers). For debugging only.
-to_pod file
try to convert file from TeX to POD format. Will only work on some subset of PARI User's Manual (Chapter 3, reference card). This
should be the only arguments on the command line.
ENVIRONMENT
COLUMNS
number of columns available on screen (for detex mode)
DISPLAY
where to launch the dvi previewer. If unset, detex mode is assumed automatically.
GPDOCDIR
directory where PARI help files are located. Default value set at Configure time.
GPTMPDIR
directory where temporary files are written
GPXDVI
dvi previewer to use
FILES
gp the gp calculator
gphelp the gphelp script
users.dvi
PARI/GP User's Manual
tutorial.dvi
PARI/GP tutorial
refcard.dvi
GP reference card
refcard.ps
GP reference card, printer ready
BUGS
The search algorithm is rather crude and the data searched rather unstructured. Hence, searching outside of Chapter 3 may not yield useful
results, except in apropos mode (sections may be truncated too soon for instance).
Multiword search patterns have a tendency to fail due to various TeX constructs in the source.
