Strings need quoting via `quote_` or `multiline_quote_`, while variables require scrubbing with `getVariableName` to ensure they are ASCII and don't clash with reserved words. Finally, the processed field value is inserted into the code string. The completed code string is returned depending on the specific type of block.\n"],null,["# Transform field values\n\nMost field values are ready to be concatenated to your code string immediately.\nHowever, some field values require extra work before they are usable.\n\nStrings\n-------\n\nStrings need to be quoted with either `quote_` or `multiline_quote_` before they\ncan be concatenated. These functions perform language-specific character\nescaping, such as replacing `'` with `\\'` in JavaScript. \n\n // For a single line text field.\n const str = generator.quote_(block.getFieldValue('STR'));\n\n // For a multiline text field.\n const str = generator.multiline_quote_(block.getFieldValue('STR'));\n\n| **Note:** the `quote_` and `multiline_quote_` methods follow an earlier naming convention with underscores, but they are public.\n\nVariables\n---------\n\nFor the built-in variable field, `getFieldValue` returns a variable ID, not a\nvariable name. To get an actual variable name, call `getVariableName` in the\ncode generator. This returns a name that is both unique and legal. Among other\nthings, `getVariableName`:\n\n- Converts the non-ASCII characters to ASCII. This is necessary because users can enter variable names in their own language. For example, it converts \"`متغير`\" to \"`_D9_85_D8_AA_D8_BA_D9_8A_D8_B1`\".\n- Ensures variable names follow the rules set forth by programming languages. For example, it converts spaces to underscores and adds the prefix `my_` to variable names that start with a digit.\n- Resolves conflicts with reserved words or other variable or function names. For example, it converts `for` to `for2`.\n\n const identifier = generator.getVariableName(block.getFieldValue('VAR'));\n\nDropdowns\n---------\n\nFor the built-in dropdown field, `getFieldValue` returns a language-neutral\nstring that might not be directly usable in code. For example, a dropdown\ncontaining comparison operators might return `'EQUALS'`, `'LESS'`, or\n`'GREATER'`. This can be used to look up a string that is used in code. \n\n const OPERATORS = {\n EQUALS: '==',\n LESS: '\u003c',\n GREATER: '\u003e',\n };\n const operator = OPERATORS[block.getFieldValue('OPERATOR')];\n\nCheckboxes\n----------\n\nFor the built-in checkbox field, `getFieldValue` returns `'TRUE'` or `'FALSE'`.\nHow you use this depends on the meaning of the checkbox. For example, you might\nuse it for branching while generating code."]]
