mg_tex2idl.pro
Converts simple TeX notation to IDL format codes used in graphics output. Only handles subscripts, superscripts, and sequences listed below.
Other file information
- Todo:
should be able to handle fractions too, use 190 (276 octal) to draw fraction bars, and !A/!B to go above/below the bar; decide whether to use \frac{1}{2}
Routines
Routines from mg_tex2idl.pro
result = mg_subsuper(token, level=long)Translate TeX superscript (^) or subscript (_) to proper IDL format codes.
result = mg_matchdelim(input)Returns the position in the input string of the closing curly brace that matches the first open curly brace, -1L if not found.
result = mg_strcnt(input, substr)Count number of occurrences of a substring in a string.
result = mg_nexttoken(str, tokens [, position=long])Find the next token in a given string.
result = mg_token(str, token)Find a substring in an input string, return the portion of the input string before the substring, and modify the input string to contain only the portion of the string after the token.
result = mg_convert_subsuper(input [, level=long])Convert TeX superscripts and subscripts in a given string to IDL format codes.
result = mg_convert_fraction(input [, /postscript])Convert TeX fractions in a given string to IDL format codes.
result = mg_textable( [/postscript])Returns table containing allowable TeX sequences and their translation to IDL.
result = mg_tex2idl(input [, font=long])Convert a TeX string to a string with embedded IDL format codes.
Routine details
top mg_subsuper
result = mg_subsuper(token, level=long)
Translate TeX superscript (^) or subscript (_) to proper IDL format codes.
Return value
string
Parameters
- token in required type=string
either ^ or _, others will return an empty string
Keywords
- level in required type=long
set to subscript/superscript level to get appropriate format code
top mg_matchdelim
result = mg_matchdelim(input)
Returns the position in the input string of the closing curly brace that matches the first open curly brace, -1L if not found.
Return value
long
Parameters
- input in required type=string
input string to search
top mg_strcnt
result = mg_strcnt(input, substr)
Count number of occurrences of a substring in a string.
Parameters
- input in required type=string
string to search
- substr in required type=string
substring to search for
top mg_nexttoken
result = mg_nexttoken(str, tokens [, position=long])
Find the next token in a given string.
Return value
string
Parameters
- str in required type=string
string to search
- tokens in required type=string
tokens
Keywords
- position out optional type=long
position in str of next token
top mg_token
Find a substring in an input string, return the portion of the input string before the substring, and modify the input string to contain only the portion of the string after the token.
Return value
string
Parameters
- str in out required type=string
input string; the output value of this string is the remaining portion of the string after the token
- token in required type=string
substring to find in the input string
top mg_convert_subsuper
result = mg_convert_subsuper(input [, level=long])
Convert TeX superscripts and subscripts in a given string to IDL format codes.
Return value
string
Parameters
- input in required type=string
input string to process
Keywords
- level in optional type=long
set to subscript/superscipt level to indicate which format code is used to format it (and hence !E and !I are used instead of !U and !D)
top mg_convert_fraction
result = mg_convert_fraction(input [, /postscript])
Convert TeX fractions in a given string to IDL format codes.
Return value
string
Parameters
- input in required type=string
input string to process
Keywords
- postscript in optional type=boolean
set to use postscript fonts
top mg_textable
result = mg_textable( [/postscript])
Returns table containing allowable TeX sequences and their translation to IDL.
Return value
strarr(2, n)
Keywords
- postscript in optional type=boolean
set to use postscript fonts
top mg_tex2idl
result = mg_tex2idl(input [, font=long])
Convert a TeX string to a string with embedded IDL format codes.
Return value
string or strarr
Parameters
- input in required type=string/strarr
input TeX string or strarr
Keywords
- font in optional type=long
set to -1 to translate for vector fonts, 0 for hardware fonts
