# Overview
`st` is a command-line tool to investigate and (ultimately) author shape tables for inclusion in Applesoft programs.
Samples are extracted from the [original Mouse Maze](https://github.com/a2geek/mouse-maze-2001/tree/master/doc/original), written in 1983.
# Usage
```shell
$ st --help
Usage: st [-hV] [--debug] [COMMAND]
Shape Tools utility
Options:
--debug Dump full stack traces if an error occurs
-h, --help Show this help message and exit.
-V, --version Print version information and exit.
Commands:
extract Extract shapes from shape table
generate Generate a shape table from source code
help Displays help information about the specified command
```
## Sub-command extract
```shell
$ st extract --help
Usage: st extract [-hO] [--skip-empty] [--stdin] [--stdout]
[--border=<borderStyle>] [--coding=<codeStyle>]
[--format=<outputFormat>] [-o=<outputFile>] [-w=<width>]
[--shapes=<shapeNums>]... [<inputFile>]
Extract shapes from shape table
Parameters:
[<inputFile>] File to process
Options:
--border=<borderStyle> Set border style (none, simple, box)
Default: simple
--coding=<codeStyle> Select source style (bitmap, long, short)
Default: long
--format=<outputFormat>
Select output format (text, source, png, gif, jpeg,
bmp, wbmp)
Default: text
--shapes=<shapeNums> Extract specific shape(s); formats are '1' or '1-4' and
can be combined with a comma
--skip-empty Skip empty shapes
--stdin Read from stdin
--stdout Write to stdout
-h, --help Show help for subcommand
-o, --output=<outputFile> Write output to file
-O, --optimize Optimize vector shapes (source only)
-w, --width=<width> Set width (defaults: text=80, image=1024)
```
## Sub-command generate
```shell
$ st generate --help
Usage: st generate [-h] [--demo-code] [--single] [--stdin] [--stdout]
[--address=<address>] [--name=<realName>] [-o=<outputFile>]
[<inputFile>]
Generate a shape table from source code
Parameters:
[<inputFile>] File to process
Options:
--address=<address> Address for AppleSingle file
Default: 24576
--demo-code Generate a ProDOS .po image with Applesoft BASIC code
demoing the shape table
--name=<realName> Filename assign in AppleSingle file
Default: SHAPES.BIN
--single Write to AppleSingle file (requires address, defaults to
0x6000)
--stdin Read from stdin
--stdout Write to stdout
-h, --help Show help for subcommand
-o, --output=<outputFile> Write output to file
```
# Features
## Text extract
```shell
$ st --debug extract --stdout --border=box --skip-empty --format=text --width=132 ~/Downloads/shapes/NEW\ MOUSE

## Graphics extract
```shell
$ st --debug extract --shape 3 --output robot.png --format png --border box ~/Downloads/shapes/NEW\ MOUSE
```
![Shape #3](images/robot.png "Robot")
```shell
$ st --debug extract --output=new-mouse-shapes.png --border=box --skip-empty --format=png ~/Downloads/shapes/NEW\ MOUSE
```
![All shapes](images/new-mouse-shapes.png "All shapes")
## Shape generation
These samples show a variety of input methods and pipes the resulting (binary) shape table back to `st` to display the results. (Otherwise it's a bit hard to demonstrate!)
### Apple 'box'
```shell
$ cat api/src/test/resources/box-longform.st
; A vector box as given by Applesoft BASIC Programmer's Reference Manual
; Notes:
; move[up|down|left|right] = move vector
; plot[up|down|left|right] = plot vector
; whitespace is ignored
; case insensitive
.long label-long
movedown 2
plotleft 2
moveup
plotup 3
moveright
plotright 3
movedown
plotdown 3
moveleft
plotleft
$ st generate --stdout api/src/test/resources/box-longform.st | st extract --stdin --stdout
+-----+
|.XXX.|
|X...X|
|X.+.X|
|X...X|
|.XXX.|
+-----+
```
### The Mouse Maze mouse
```shell
$ cat mouse.st
; extracted from NEW MOUSE
.bitmap
..........*X..
....XXXX.XX...
...XXXXXXXX...
.XXXXXXXXXXX..
XX.XXXXXXX.XX.
X...XXXXXXXXXX
XX............
.XXX.XX.......
...XXX........
$ st generate --stdout mouse.st | st extract --format=source --coding=short --stdin --stdout
.short
DDDRDDRRUlLdlLLLLLLURRRRRULLLLLLDUlLDLDDRDRRDRRURUuluuruRRRULlLLDLLUrRrrrurrrU
```
## Generate to AppleSingle
```shell
$ cat api/src/test/resources/box-longform.st | st generate --stdin --stdout --single | asu info --stdin
Real Name: SHAPES.BIN

Access: 0xC3

## Generate demo disk
Demonstration of a Beagle Bros font:
```shell
st --debug extract --format=source --coding=short ~/Downloads/shapes/\]WESTERN.dump --stdout --skip-empty --optimize |
st generate --demo-code -o western.po --stdin
```
![Western Font Demo](images/western-font-demo.png "]WESTERN")
