Member Function Documentation

addDoubleQuotes()

String org.lflang.util.StringUtil.addDoubleQuotes ( String str )

static

camelToSnakeCase()

String org.lflang.util.StringUtil.camelToSnakeCase ( String str )

static

Convert a string in Camel case to snake case.

E.g. MinimalReactor will be converted to minimal_reactor. The string is assumed to be a single camel case identifier (no whitespace).

hasQuotes()

boolean org.lflang.util.StringUtil.hasQuotes ( String str )

static

Return true if the given string is surrounded by single or double quotes,.

joinObjects()

static< T > String org.lflang.util.StringUtil.joinObjects ( List< T > things, String delimiter )

static

normalizeEol()

String org.lflang.util.StringUtil.normalizeEol ( String s )

static

Normalize end-of-line sequences to the Linux style.

removeQuotes()

String org.lflang.util.StringUtil.removeQuotes ( String str )

static

If the given string is surrounded by single or double quotes, returns what's inside the quotes.

Otherwise returns the same string.

Returns null if the parameter is null.

trimCodeBlock()

String org.lflang.util.StringUtil.trimCodeBlock ( String code, int firstLineToConsider )

static

Intelligently trim the white space in a code block.

The leading whitespaces of the first non-empty code line is considered as a common prefix across all code lines. If the remaining code lines indeed start with this prefix, it removes the prefix from the code line.

For examples, this code

int test = 4;
if (test == 42) {
    printf("Hello\n");
}

will be trimmed to this:

int test = 4;
if (test == 42) {
    printf("Hello\n");
}

Parameters

code	the code block to be trimmed
firstLineToConsider	The first line not to ignore.

Returns

trimmed code block
