I don't have exactly what you're looking for but this could be a start:
NB.* parseIniFile: return 2-column mat (0: section name; 1: name/value
pairs)
NB. given INI file name.
parseIniFile=: 3 : 0
inifl=. f2v y.
whbrkt=. -._1 e.&>,&.>(<'^\[.*\]') rxmatch&.>dlb&.>inifl
nvp=. elimEmptyRows&.>nvPair&>&.>whbrkt<;._1 inifl
((}.@:}:@:dlb@:dtb)&.>whbrkt#inifl),.nvp
NB.EG inifl=. f2v WINDIR,'cdPlayer.ini'
)
NB.* nvPair: Name=Value pair from string of form 'Name=Value'.
nvPair=: 13 : '0 1}.&.>(y.i.''='')({.;}.)y.'
NB.* elimEmptyRows: eliminate rows of boxed mat if all items empty.
elimEmptyRows=: 13 : 'y.#~0+./ . ~:|:#&>y.'
This requires 'regex' and the standard deblanking utilities "dlb" and "dtb",
as
well as these 2 utilities (which I think have standard J-equivalents but I
haven't
looked them up):
f2v=: 3 : 0
NB.* f2v: File to Vector: read file -> vector of lines.
vec=. l2v 1!:1 <y.
)
l2v=: 3 : 0
NB.* l2v: Lines to Vec: convert lines terminated by LF to vector elements.
vec=. y.
if. 0~:#y. do.
vec=. vec-.CR NB. Use only single-char for line
delimiter
vec=. vec,(LF~:{:vec)#LF NB. Ensure terminal line delimiter
whq=. ~:/\'"'=vec NB. Mask interiors of quoted strings
ptn=. LF=vec NB. Partition lines but
ptn=. ptn*.-.whq*.ptn NB. exclude quoted end-of-lines
vec=. ptn <;._2 vec NB. Make into vector of lines
end.
vec
)
So, for example:
$ii=. parseIniFile WINDIR,'cdPlayer.ini'
42 2
2{.ii
