Zlib

Attention KoLmafia Users!

This page details the use of functions in a script library. The information here is only useful to those who have followed the included steps to make use of these functions; they are not built-in to KoLmafia.

About ZLib

ZLib is a function library intended to make life easier for both script authors and script users. A more detailed introduction, as well as the current version and instructions on installing it, can be found in the ZLib thread.

Functions

string excise(string source ,string start ,string end )

The original source string
start after this string
end before this string

This function returns a portion of the source string, from after the first occurrence of start to just before the first occurrence of end. If either start or end are missing, it will return an empty string. You can also supply either start or end as blank strings to specify the actual start or end of the source string.

string normalized(string mixvar ,string type )

mixvar is the string to normalize
type is the datatype to normalize to, which can be any primitive type or any typed constant. You can also specify "list of <type>", for a comma-delimited list of the given type.

Returns mixvar, normalized to the specified KoLmafia type. For example, normalized("badger", "familiar") would return "Astral Badger". It can also normalize comma-delimited lists of any of these types if you specify "list of <type>" for type. For example, normalized("bloop, dair go, possess", "list of monster") would return "Blooper, Dairy Goat, Possessed Silverware Drawer".

string rnum(int n )

string rnum(float n )

string rnum(float n ,int place )

n is a number
place is the number of decimal places to round to

Returns your number n as a human-readable string. For ints, this means it adds commas where appropriate. For floats, it also rounds to the nearest place after the decimal. Default place for the float-only version is 2, although it may display fewer digits if they are 0's. Examples: rnum(12580) => "12,580", rnum(3.14152964,3) => "3.142", rnum(4.00008) => "4", rnum(123456789.87654321) => "123,456,789.88". Recommended as a substitute for to_string(int).

void set_avg(float to_add ,string which_prop )

to_add is the data point to add
which_prop is the property to add data to

Useful for adding spading to scripts. Adds one more statistic to an average value being stored in a property. For example, calling this script three times with the values 2, 4, and 6 for to_add would result in the property which_prop containing "4.0:3", with 4.0 being the average of the three numbers added and 3 being the amount of numbers averaged.

float get_avg(string which_prop )

which_prop is the property to access

Returns an average value set by set_avg().

float eval(string expression ,float [string] values )

expression is the base expression
values is a map of values to replace

By Jason Harper. Evaluates expression as a math expression, and allows you to substitute values for variables, as described in much greater detail here. A brief version of this documentation is also included in ZLib. (NB: This section needs more infoz.)

boolean vprint(string message ,int level )

boolean vprint(string message ,string color ,int level )

message and color are used as in the function print()
level is a verbosity reference

Wrapper for print() and abort(), prints message depending on vars["verbosity"] setting. It has a boolean return value so it can replace { print(message); return t/f; } if level == 0: abort with message if level > 0: prints message if verbosity >= level, returns true if level < 0: prints message if verbosity >= abs(level), returns false

First, level controls the return value -- if it is positive, vprint will return true; if negative, it will return false. If level is 0, vprint() will abort with the specified message. You can see now that vprint already replaces both abort() and print(). I recommend using it in place of abort() in case a savvy user wishes to avoid or otherwise handle aborts somehow.

Secondly, level controls whether or not the message is actually printed to the CLI, depending on your verbosity setting (a ZLib setting, default 3). If the absolute value of level is more than verbosity, the message will not be printed. This allows users to control the chattiness of scripts, and allows authors to include debug print statements which can be shown by setting verbosity high.

Recommendations for Verbosity Levels in vprint()

0: abort error

+/- 1: absolutely essential (and non-cluttering) information -- use very sparingly, since a verbosity of 1 is basically "silent mode"

+/- 2: important and useful info -- this should generally be your base level for your most important messages

+/- 4: interesting but non-essential information

+/- 6: info which an overly curious person might like to see on their CLI

+/- 10: details which are only helpful for debugging, such as "begin/end functionname()" or "current value of variable: value"

This will allow users who want extra levels of detail printed to see that detail without cluttering the CLI for users who don't prefer to see all the details. In addition, it allows users to specify a verbosity of 0 to see ONLY mafia output (no script output at all), which could prove handy.

The color parameter is optional. If you omit it, the default color is black for positive values of level, and red for negative values. Usually, you won't be calling vprint() with the color parameter, unless you want to specify a different color or override the default colors.

boolean vprint_html(string message ,int level )

message is used as in the function print_html()
level is a verbosity reference

Same as vprint() above, but wraps print_html().

float abs(float n )

n is a number of either int or float type.

Returns the absolute value of the number n in the same datatype as supplied.

float minmax(float a ,float min ,float max )

a is the original number
min is the minimum return value
max is the maximum return value

Returns a, but no less than min and no more than max.

string check_version(string software ,string property ,string this_version ,int thread )

software is the script name, which must match the page source of the thread being parsed
property is used as part of the name of the property saved to user preferences
this_version is the version of the script currently running
thread is the script's thread-number on kolmafia.us

Server-friendly once-daily version-checking. If the user hasn't checked yet today, visits the specified thread on the kolmafia.us forums to find the current version of your script. The thread must include "<b>software version</b>" for the version info to be successfully parsed. Optionally, you may include "[requires revision XXXX]" somewhere in your post if you want to indicate a required minimum revision of mafia. If a new version is available, it alerts the user in large text and provides an update link, then waits for a sufficiently annoying interval in case the user wishes to abort operation to go update the script. The return value is a blank string unless an update is found, in which case it is a <div class='versioninfo'> containing the update message. This allows this function to work equally well for relay scripts. The current version (and the last date checked) is stored in a data file "zversions.txt". Example:

check_version("Hardcore Checklist","checklist","1.2.7",1045);

boolean load_current_map(string map_name ,aggregate destination )

map_name is the name of the map, without the file extension
destination is a previously-declared map to load with data

Acts as a wrapper for the built-in file_to_map() with automatic update capability. The first time the function is called for a given map each day, it will check Zarqon's Map Manager to see if an update for the given map_name is available, and if so will load from there. Otherwise, it merely loads it from disk. (Note: you should not include a file extension, such as ".txt" in the map_name parameter.)

void setvar(string name ,mixed dfault )

dfault can be any primitive or ASH type (e.g. item, effect, coinmaster, etc.), but not an array, map, or record.

This function ensures that a ZLib script setting called default) exists. If not, it creates it and sets it to default). If the setting already exists, it does nothing. Note that this function does not edit existing settings. That is done by calling ZLib in the CLI.

For Users

Script settings are now all saved in one place, separate from mafia properties. I've read more than one post wishing that script-defined settings and mafia properties would be separate. This provides a solution.
Script settings are independent from scripts. This means that you will no longer need to edit scripts to adjust your settings. Further, when you download a script update, the script will still use your saved settings and you won't need to reset them!
To see all of your current settings, type "zlib vars" in the CLI. You can also type "zlib <whatever>" to see a list of current settings and values containing <whatever>. To change a setting, type "zlib settingname = value". If you're adjusting threshold, you can use "up" or "down" as the value to adjust your threshold relatively. This is almost exactly as convenient as mafia settings (possibly more so since you don't need to open a text file to find setting names!).
If for some reason you prefer to open a text file, ZLib settings are stored in a file called vars_myname.txt in your data directory.
Scripts that use Zlib script settings will only create these settings when you run them for the first time. Attempting to edit a nonexisting setting won't work, so you'll need to run a script once (then, usually, mash the ESC key before it actually does anything) before you can configure it. Script documentation should tell you which settings to change to get your desired behavior.

For Script Authors

Script settings may now be used across scripts, in exactly the same way that mafia properties are. Basically, this works almost exactly like mafia properties, except that new settings can only be created by setvar() or manually editing the file ("zlib nonexistentsetting = value" will fail).
Settings are only stored if you run a script that defines/uses them. So your settings file will not contain any extraneous unused settings.
Script authors can now test for a setting's existence, which means you can check to see if a user has used a given script. It's almost as good as a script_exists() function. This can allow scripts to work together with other scripts, if they exist!
Scripts with overlapping or related functionality can be designed to access a single shared setting, in much the same way that my scripts have until now all shared a "threshold" mafia setting. Changing a single setting can now change the behavior of every script that accesses that setting.

Functional Details

When importing ZLib, it loads a map of your script settings from vars_myname.txt. It is a basic string[string] map called vars. To access a script setting within an ASH script, use vars[varname]. To check if a setting exists you can simply use if (vars contains varname).

When a script calls setvar("threshold",4), ZLib checks to see if a variable called "threshold" already exists in vars. If so, since dfault is an integer, it ensures that the value is an integer using normalize() (saving changes if necessary), but unless normalization changed the value, nothing else happens. If "threshold" does not exist in vars, it creates it, sets it to 4, and saves the updated map back to vars_myname.txt.

Choosing Setting Names

The file of script settings will contain all script settings, sorted alphabetically. Also, there is no way to detect if a setting is unused, so if you decide to change the name, the old setting will never be deleted. Please think carefully about your setting names. If you have a setting named "setting1", a user will probably not have a clue which script that is for or what it does. True, this can be overcome with documentation, but it is far better to have settings that make sense just by looking at them.

Recommendations:

1. Use a name that clearly identifies what the setting is/does.

2. Prefix your setting names with a script identifier. For example, here are some of my One-Click Wossname script settings:

setvar("ocw_warplan","optimal");
setvar("ocw_change_to_meat",true);
setvar("ocw_nunspeed",false);
setvar("defaultoutfit","current");
setvar("ocw_f_default","zombie");
setvar("ocw_m_default","");

Those settings which are specific to OCW are prefixed with "ocw_" so as to be found together in the settings file. However, some of the settings are usable across scripts, and are not so prefixed. For example, the "defaultoutfit" will be used by nearly all of my adventuring scripts that swap outfits, so no prefix is given.

boolean be_good(string johnny )

johnny is the thing you want to check -- usually an item or familiar

This function, originally created to check whether items were allowed in the Bees Hate You path, has been expanded to an all-purpose check to see whether something is acceptable in your current path. For example, in a Trendy path, outdated items would not be_good. Likewise, during Bees Hate You, a familiar containing a 'b' would not be_good. In Fistcore, anything you hold in your hands is not allowed. And so forth.

[[Data Types#boolean[string]|boolean[string]]] tower_items(boolean combat_safe )

combat_safe is optional. Supply it as true if you are in combat.

This handy function simply returns a map of the items definitely need (value: true) or might need (value: false) to climb the tower. You can check (tower_items() contains X) to determine whether an item has a nonzero chance of being required for the tower, or check tower_items(X) to determine whether an item has a 100% chance of being needed (i.e. you saw it from your telescope). If you haven't yet checked your telescope yet this run, it will do that to populate the mafia properties, unless you have supplied the optional combat_safe parameter as true (you can't access your telescope during combat).

int have_item(string to_lookup )

to_lookup is the item to count

A residual function, used by the following and probably in several other scripts. Returns the amount of an item you have both in your inventory and equipped. Similar but not equivalent to the ASH function available_amount(), since this function completely ignores your closet and storage.

float isxpartof(item child ,item ancestor )

child is the ingredient/component you want to check.
ancestor is the concoction you want to check.

In the sentence "child is X part of ancestor", this function returns X. It assumes the minimum amount of other ingredients necessary. For example, isxpartof($item[white pixel], $item[digital key]) returns 0.033333335 (1/30), since 30 white pixels are needed. However, isxpartof($item[red pixel], $item[digital key]) returns 0.03125 (1/32), assuming 1 each of green and blue pixels and 29 other white pixels (rather than 30 each RGB pixels -- 1/90). This function is used by has_goal(item) but may have uses in your own script.

float has_goal(item check_me )

float has_goal(monster check_me )

float has_goal(location check_me )

check_me is the item, monster or locationto check

At the base of this function is the item parameter version, which returns the chance that the item check_me is or results in a goal. If the item is itself a goal or it's your current bounty item, returns 1.0. Otherwise, returns what percentage of a goal the item is, which could be nonzero in two cases: 1) you could get a goal by using the item (returns the chance of success), or 2) the item is an ingredient of a goal. For example, with a goal of black pepper, has_goal($item[black picnic basket]) would return 0.58.

When supplied a monster as the parameter for check_me, returns the percent chance that encountering the given monster will result in a goal, taking into account +items, pickpocket availability (and +pickpocket), and Torso. For instance, with no +item and black pepper as a goal, has_goal($monster[black widow]) would return 0.087 (0.58 basket contains pepper * 0.15 basket drop rate). Also note that it will add multiple goals together, so with white pixels as a goal, a Blooper would return 2.1.

When supplied a location as the parameter for check_me, returns the chance that adventuring at a given location will yield a goal. For our black pepper example, has_goal($location[black forest]) would return 0.0174 (0.2 black widow appearance rate * 0.087 chance that a widow has black pepper). Presently this accounts for combat frequency modifiers but not Olfaction, and it will be off for areas with noncombats that grant goals, because it assumes that all noncombats do not yield items.

These functions also have an optional boolean parameter, usespec. If supplied as true, these functions will use speculative values. (See "whatif")

boolean obtain(int qty ,string condition ,location place )

boolean obtain(int qty ,string condition ,location place ,string filter )

qty is the quantity of the item or choice adventure desired
condition is the item or choice adventure to use as a goal
location is the place to adventure to obtain your goal
filter is an optional combat filter used the same as in adventure()

Attempts to get qty (minus existing) of condition, either by purchasing (if you have the KoLmafia preference set), pulling from Hangk's, or adventuring at the specified place. It also works with choice adventures.

boolean use_upto(int qty ,item thing ,boolean purchase )

qty is the quantity to use
thing is the item to use
purchase is true if KoLmafia should purchase extras if you don't already have qty

Gets (if purchase is true) and uses qty of the item(s) thing if possible. Otherwise, uses as many as you have up to qty.

boolean resist(element resist_it ,boolean really )

resist_it is the element to resist
really is true to actually attemp resistance, false to check only

Returns whether you are able to resist a given element resist_it, or if really is true, attempts to actually achieve that resistance (casting buffs, changing gear, or equipping your Exotic Parrot) and returns its success.

int my_defstat(boolean usespec )

usespec is optional. If true, uses speculative values rather than real values.

Returns the value of your buffed defense stat, taking into account Hero of the Half-Shell.

int get_safemox(location where )

where is the location to check for safe moxie

Using mafia's location/monster data, returns the safe moxie of a given zone where.

boolean auto_mcd(int check_me )

boolean auto_mcd(monster check_me )

boolean auto_mcd(location check_me )

check_me is the int, monster or location to check

If your ZLib setting "automcd" is true, automatically adjusts your mind-control device for maximum stat gains based on safe moxie and your ZLib "threshold" setting. Does not adjust for MCD-sensitive areas (certain bosses, Slime Tube), or areas with no known combats. Returns true unless KoLmafia is unable to do so, even though the script thinks it should be capable (still returns true if you can't currently access an mcd-changing device).

familiar best_fam(string type )

type is the type of familiar ability to check for

Returns your heaviest familiar of a given type (currently possible: items, meat, produce, stat, delevel). If your ZLib "is_100_run" setting is anything other than $familiar[none], returns that familiar (so you don't have to make the check in your script).

boolean send_gift(string recipient ,string message ,int_meat ,int [item] goodies )

boolean send_gift(string recipient ,string message ,int meat ,int [item] goodies ,string inside_note )

recipient is the player to send to
message is the outside message
meat is the amount of meat to send
goodies is a map of items & amounts to send
inside_note is an optional inside message

Sends a gift to a player. Able to split large amounts of items. Returns true if the package is sent and false if not. See kmail() below.

boolean kmail(string recipient ,string message ,int_meat ,int [item] goodies )

boolean kmail(string recipient ,string message ,int_meat )

boolean kmail(string recipient ,string message ,int meat ,int [item] goodies ,string inside_note )

recipient is the player to send to
message is the outside message
meat is the amount of meat to send
goodies is an optional map of items & amounts to send
inside_note is an optional inside message if sent as a gift

Sends a kmail to player recipient, returning true if the kmail is successfully sent. Handles splitting the message into multiple messages if the number of item types in goodies is too large. Returns the result of send_gift() if the intended recipient is unable to receive the message due to being in HC or somesuch. Note that you can also specify the inside_note to be used inside gifts in that case. Use "\n" to specify a new line in the message.

Making use of Zlib

To include this library in your script, first you must download it from the location provided below and make sure it is in your /scripts directory (or a sub-directory thereof). Then, simply add the following towards the top any script in which you wish to have access to these functions:

import "zlib.ash";

Then all these functions will be available in your script. Have fun!
