Thanks for your grammar :).
I extended the grammar and it now is able to parse all *.bp files i have
tested from the android10_r52 source tree!
That means i now have to do something useful with the peg tree. How does
it work? I don'tknow exactly what to do from here. I guess i have to walk
the tree somehow and execute the rules as i go, but i don't have a clue
how to do this :/.
The current program looks like this:
(use-modules (ice-9 peg)
(ice-9 pretty-print)
(ice-9 rdelim))
(define *bp*
(read-delimited "" (open-input-file (cadr (command-line))) 'concat))
(define-peg-string-patterns
"blueprint <-- (comment* (ws? defvar ws?)* module* comment*)* .*
module <-- rule ws? map ws?
rule <-- 'cc_binary_host' / 'cc_test_library' / 'cc_test_host' /
'cc_binary' / 'cc_test' /'cc_library_host_static' /
'cc_library_static' / 'cc_library_shared' /
'cc_library_headers' / 'cc_library' / 'cc_defaults' /
'cc_benchmark' / 'python_test_host' / 'genrule' / 'filegroup' /
'ndk_headers' / 'ndk_library' / 'llndk_library' /
'python_binary_host' / 'cc_prebuilt_binary' / 'prebuilt_etc' /
'python_defaults' / 'phony'
defvar <-- var ws? eq ws? value
eq < '='
nl < '\n'
ws < (' ' / '\t' / nl)+
comma < ','
colon < ':'
maplb < '{'
maprb < '}'
listlb < '['
listrb < ']'
comment < ws? '//' ( . !nl )* . ws?
strb < '\"'
append <-- '+'
key <-- ws? (comment ws?)* [-a-zA-Z0-9_]+
bool <-- 'true' / 'false'
integer <-- '-'? [0-9]+
string <-- strb (. !strb)* . strb
map <-- maplb ws? maprb / maplb ws? attribute (comma comment* ws?
attribute)* comma? ws? maprb
attribute <-- key ws? colon ws? expr
expr <-- (value ws? append ws? &value)* value
value <-- bool / integer / string / map / list / var
var <-- [-a-zA-Z0-9_]+
list <-- listlb ws? listrb / listlb ws? comment* ws? value (comma
comment* ws? value)* comma? ws? comment* listrb
")
(pretty-print (peg:tree (match-pattern blueprint *bp*)))
And a *very long* parse tree is here:
