How can I refactoring the next lines to join to conditions in one with OR operator?
if [[ "$lexer_date" > "$lexer_ts_date" ]]; then
generate_grammar
elif [[ "$parser_date" > "$parser_ts_date" ]]; then
generate_grammar
fi
Something like this:
if lexer_date > lexer_ts_date or parser_date > parser_ts_date: generate_grammar
The or operator is ||
if [[ "$lexer_date" > "$lexer_ts_date" || "$parser_date" > "$parser_ts_date" ]]; then
generate_grammar
fi
or
((lexer_date>lexer_ts_date|parser_date>parser_ts_date)) && generate_grammar
Test script:
$ cat test
#!/bin/bash
lexer_date=2
lexer_ts_date=1
parser_date=2
parser_ts_date=1
generate_grammar(){ echo ok; }
((lexer_date>lexer_ts_date|parser_date>parser_ts_date)) && generate_grammar
Testing:
$ ./test
ok
