Put + after a boolean switch option to enable it, - to disable it
@<x> : Read compiler options from file <x> in addition to the default
pas2js.cfg
-B : Rebuild all
-d<x> : Defines the symbol <x>. Optional: -d<x>:=<value>
-i<x> : Write information and halt. <x> is a combination of the following:
-iD : Write compiler date
-iSO : Write compiler OS
-iSP : Write compiler host processor
-iTO : Write target platform
-iTP : Write target processor
-iV : Write short compiler version
-iW : Write full compiler version
-ic : Write list of supported JS processors usable by -P<x>
-im : Write list of supported modeswitches usable by -M<x>
-io : Write list of supported optimizations usable by -Oo<x>
-it : Write list of supported targets usable by -T<x>
-iJ : Write list of supported JavaScript identifiers -JoRTL-<x>
-C<x> : Code generation options. <x> is a combination of the following
letters:
o : Overflow checking of integer operations
r : Range checking
R : Object checks. Verify method calls and object type casts.
-F... Set file names and paths:
-Fe<x>: Redirect output to file <x>. UTF-8 encoded.
-FE<x>: Set main output path to <x>
-Fi<x>: Add <x> to include paths
-FN<x>: add <x> to namespaces. Namespaces with trailing - are removed.
Delphi calls this flag "unit scope names".
-Fu<x>: Add <x> to unit paths
-FU<x>: Set unit output path to <x>
-I<x> : Add <x> to include paths, same as -Fi
-J... Extra options of pas2js
-Jc : Write all JavaScript concatenated into the output file
-Je<x>: Encode messages as <x>.
-Jeconsole: Console codepage. This is the default.
-Jesystem : System codepage. On non Windows console and system are the
same.
-Jeutf-8
: Unicode UTF-8. Default when using -Fe.
-JeJSON
: Output compiler messages as JSON. Logo etc are outputted
as-is.
-Ji<x>: Insert JS file <x> into main JS file. E.g. -Jirtl.js. Can be given
multiple times. To remove a file name append a minus, e.g. -Jirtl.js-.
-Jl : lower case identifiers
-Jm : generate source maps
-Jmsourceroot=<x>: use x as "sourceRoot", prefix URL for source file
names.
-Jmbasedir=<x>: write source file names relative to directory x, default
is map file folder.
-Jminclude: include Pascal sources in source map.
-Jmabsolute: store absolute filenames, not relative.
-Jmxssiheader: start source map with XSSI protection )]}', default.
-Jm-: disable generating source maps
-Jo<x>: Enable or disable extra option. The x is case insensitive:
-JoSearchLikeFPC: search source files like FPC, default: search case
insensitive.
-JoUseStrict: add "use strict" to modules, default.
-JoCheckVersion-: do not add rtl version check, default.
-JoCheckVersion=main: insert rtl version check into main.
-JoCheckVersion=system: insert rtl version check into system unit init.
-JoCheckVersion=unit: insert rtl version check into every unit init.
-JoRTL-<y>=<z>: set RTL identifier y to value z. See -iJ.
-Jr<x> Control writing of resource string file
-Jrnone: Do not write resource string file
-Jrunit: Write resource string file per unit with all resource strings
-Jrprogram: Write resource string file per program with all used
resource strings in program
-Jr<x> Control writing of linked resources
-JRnone: Do not write resources
-JRjs: Write resources in Javascript structure
-JRhtml[=filename] : Write resources as preload links in HTML file
(default is projectfile-res.html)
-Jpcmd<command>: Run postprocessor. For each generated js execute command
passing the js as stdin and read the new js from stdout. This option can be added
multiple times to call several postprocessors in succession.
-Ju<x>: Add <x> to foreign unit paths. Foreign units are not compiled.
-JU: This pas2js does not support PCU files
-l : Write logo

-MDelphi: Delphi 7 compatibility mode
-MObjFPC: FPC's Object Pascal compatibility mode (default)
-M<x> : enable or disable modeswitch, see option -im
Each mode (as listed above) enables its default set of modeswitches. Other

-n : Do not read the default config files
-o<x> : Change main JavaScript file to <x>, "." means stdout

-O- : Disable optimizations
-O1 : Level 1 optimizations (quick and debugger friendly)

-OoRemoveNotUsedDeclarations[-]: Default enabled for programs with -Jc
