|
||
## Alpha Compiler Flags & Expected Results
|
||
### -tok
|
||
Prints the token stream provided by the Lexical Analyzer to a `.tok` file. Output can be found in `/out/<file>.tok`. Tokenization follows the specified format found in the alpha language spec.
|
||
|
||
### -st
|
||
Prints the symbol table to a file. Follows the format provided in the alpha language spec. if the `-ir` flag is also present, the symbol table will print out temporary variables. Output can be found in `out/<file>.st`.
|
||
|
||
### -asc
|
||
Prints the annotated alpha source code to a file. Will display any syntax errors that are present below the line they occur on. If more than one error is present, the messages will stack. Output can be found in `out/<file>.asc`.
|
||
|
||
### -tc
|
||
Throws type check errors to the asc output file. If the `-asc` flag is not present, no errors will be displayed. Output can be found in `out/<file>.asc`
|
||
|
||
### -ir
|
||
Prints the intermediate code representation stream to a file. Output can be found in `out/<file>.ir`. This flag modifies the `-st` flag, allowing for temporary variables to print out.
|
||
|
||
### -cg
|
||
Prints the alpha program's unique x86 assembly to a `.s` file. Assembly stream is valid x86 code that can be assembled and linked with other .s files. Output can be found in `out/<file>.s`
|
||
|
||
### -debug
|
||
Prints debug messages to the console if present. Our debug messages utilizes a wrapper function for `printf()` called `printdebug()`. This allows for us to file names, code lines, and colors!
|
||
|
||
### -help
|
||
Prints a general help message. (If you read this far, you probably won't need this flag)
|
||
|
||
|
||
## Testing
|
||
|
||
**Arguments:**
|
||
-exp Generate expected output files
|
||
-diff Compare output files with expected output files
|
||
-help Show this help message
|
||
|
||
**Usage:**
|
||
./test.sh <file.alpha> [flags] Run the test on a single file
|
||
./test.sh <directory> [flags] Run the test on all files in a directory
|
||
|
||
**Examples:**
|
||
- ./test.sh test.alpha
|
||
- - Runs test flags in header on test.alpha
|
||
- ./test.sh test/
|
||
- - Runs test flags in header on all .alpha files in test/
|
||
- ./test.sh test/ -exp
|
||
- - Runs test flags in header on all .alpha files in test/ and generates expected output files
|
||
- ./test.sh test/ -diff
|
||
- - Runs test flags in header on all .alpha files in test/ and compares output files with expected output files
|
||
- ./test.sh test/ -exp -diff
|
||
- - Runs test flags in header on all .alpha files in test/ and generates expected output files and compares output files with expected output files
|
||
|
||
**Notes:**
|
||
To create a test file, on the first line of the .alpha file, add:
|
||
(* TEST: [ <test_flags> ] *)
|
||
where <test_flags> are the alpha flags to be used. Ex:
|
||
(* TEST: [ -debug -asc -tc ] *)
|
||
|
||
|
||
|
||
## Lexical Analyzer
|
||
* **Undefined Behavior:**
|
||
* Spaces are not required between tokens. For instance, an INTEGER and an ID are valid even if there is no space between them
|
||
```
|
||
Input: *5variable*
|
||
Output: 2 14 301 "5"
|
||
1 1 101 "variable"
|
||
```
|
||
|
||
## Syntax Analyzer
|
||
* *Incomplete*
|
||
|
||
## Symbol Table
|
||
* *TODO: Create diagram.* |
