Command-Line Usage:

customasm <INPUT-FILES...> [options] <OUTPUT-GROUPS...>

Specify multiple OUTPUT-GROUPS using the – separator.

Examples:

• customasm main.asm
• customasm main.asm -f hexdump -o main.txt
• customasm main.asm -f binary -o main.bin -- -f symbols -o symbols.txt
• customasm main.asm --iters=3 -f annotated -p -- -f symbols -- -f binary

Global Options:

• -q, --quiet
  Suppress progress reports.
• -v, --version
  Display version information.
• -h, --help
  Display this information.
• -t, --iters=NUM
  The maximum number of resolution iterations to attempt.
  (Default: 10)
• -dNAME, --define=NAME
• -dNAME=VALUE, --define=NAME=VALUE Overwrites a constant definition with the given value, or true if none is given.
• --color=on/off
  Whether to style the output with colors.
  (Default: on)
• --debug-iters
  Print debug info during resolution iterations.
• --debug-no-optimize-static
  Prevent optimization of statically-known values.
• --debug-no-optimize-matcher
  Prevent optimization of the instruction matcher algorithm.

Output Options:

• -f, --format=FORMAT
  The format of the output file. See below for possible values.
• -o, --output=FILENAME
  The name of the output file.
• -p, --print
  Print the output to the screen instead of writing to a file.

Format Usage:

Use the format names below with or without the extra parameters, separated by commas, with no whitespace in between.

If the argument is a string, you’ll need to escape characters incompatible with your command-line shell. For example, spaces can be escaped as \x20. The use of surrounding double-quotes is optional, for convenience.

Examples:

• -f annotated
• -f annotated,group:4
• -f annotated,base:8,group:3
• -f list,before:"begin\x20data\n"
• -f list,before:begin\x20data\n,between:\n

Formats:

• binary
  Code compatible with your target machine.

• annotated,base:16,group:2,addr_base:16,labels:true
  Annotates the output data with excerpts from the source code.

• annotatedbin
  Same as: annotated,base:2,group:8

• binstr
  Uninterrupted string of binary digits.
• hexstr
  Uninterrupted string of hexadecimal digits.
• bindump
  Memory-dump style encoded as binary digits.

• hexdump
  Memory-dump style encoded as hexadecimal digits.

• mif
  Memory Initialization File format.

• intelhex,addr_unit:8
  Intel HEX format. addr_unit can be 8, 16, or 32.

• list,base:16,group:2,between:"",group2:16,between2:"",before:"",after:""
  Customizable list format. Digits of the selected base will be grouped in amounts given by group, separated by the string given by between. Optionally, there will be another round of grouping by group2 and between2. Output will be prefixed and suffixed by the strings given by before and after.

• deccomma
  Bytes encoded as decimal literals separated by commas.
• hexcomma
  Bytes encoded as hexadecimal literals separated by commas.
• decspace
  Bytes encoded as decimal literals separated by spaces.

• hexspace
  Bytes encoded as hexadecimal literals separated by spaces.

• decc
  Bytes encoded as decimal literals wrapped in a C-style declaration.

• hexc
  Bytes encoded as hexadecimal literals wrapped in a C-style declaration.

• logisim8
  For use with the Logisim logic simulator program.

• logisim16
  For use with the Logisim logic simulator program.

• addrspan

• tcgame,base:16,group:2
  Annotates the output data with snippets of the source code in a format compatible with the assembly editor for the game “Turing Complete”. Supports base 2 and 16. Comments out annotations with # and prefixes each group with 0x or 0b.

• tcgamebin
  Same as: tcgame,base:2,group:8

• symbols
  Lists all defined symbols with their resolved values.
• mesen-mlb
  Symbol file for usage with the Mesen NES emulator.
