mhinson 24-Jun-2009 [3109] | I am just learning everything I can, so knowing about Block Parsing sounds good to. tuples! are quite good for IP addresses, but ip addresses often need exactly 4 parts. I wonder why there are no datatypes specific for networking? e.g. networks & masks & inverse masks and domain names. and DNS records. |
Steeve 24-Jun-2009 [3110] | Mhinsob, if you load an ip address (from a string) you got a tuple, so what is different in your request ? >> type? probe load "1.2.3.4" 1.2.3.4 == tuple! |
Izkata 24-Jun-2009 [3111] | Possibly checking that it's a valid IP address? >> length? 1.2.3.4 == 4 >> length? 1.2.3.4.5 == 5 >> length? 1.2.3.44.5 == 5 |
Tomc 24-Jun-2009 [3112] | early tuples were more restrictive if I recall (max of lenght 4) but then we complained we wanted to use them for more than just networking |
BrianH 24-Jun-2009 [3113x2] | You can use up to 10 tuple elements - any higher wouldn't fit into an immediate value. |
I wonder why there are no datatypes specific for networking? In general we like our types to be more widely applicable. However, we have tuple!, url!, and port!. The rest can be handled by functions. | |
Paul 24-Jun-2009 [3115x3] | mhinson, not sure if your using R2 or R3 but if your using R2 then you might want to know about get-modes. |
>> get-modes tcp:// 'interfaces == [make object! [ name: "lo0" addr: 127.0.0.1 netmask: 255.0.0.0 broadcast: none dest-addr... >> print get-modes tcp:// 'interfaces name: "lo0" addr: 127.0.0.1 netmask: 255.0.0.0 broadcast: none dest-addr: none flags: [multicast loopback] name: "if15" addr: 169.254.102.14 netmask: 255.255.0.0 broadcast: 169.254.255.255 dest-addr: none flags: [broadcast multicast] name: "if12" addr: 192.168.1.105 netmask: 255.255.255.0 broadcast: 192.168.1.255 dest-addr: none flags: [broadcast multicast] | |
I don't know what the equivalent in R3 is. | |
BrianH 24-Jun-2009 [3118] | Nothing yet :( |
mhinson 25-Jun-2009 [3119] | The get-modes looks interesting. Can it produce information about any ip address I might give it? like 172.22.37.55/28 I suppose that is an example of a very common network address "type" |
BrianH 26-Jun-2009 [3120] | GET-MODES gets information about ports, not addresses. |
mhinson 26-Jun-2009 [3121] | Hi. is there a special function to remove the last element of a string please? this works, but seems a bit cryptic. reverse next reverse {a.b.c.} Thanks. |
Sunanda 26-Jun-2009 [3122] | These avoids the double reversal -- not sure if they are less cryptic: head clear back tail {a.b.c.} head remove back tail {a.b.c.} |
mhinson 26-Jun-2009 [3123] | Thanks Sunanda. I like clear back tail {a.b.c.} then I can directly modify my string. |
Gregg 28-Jun-2009 [3124] | Wrapping it in a func makes it less cryptic. :-) |
mhinson 4-Jul-2009 [3125] | Hi. If I obtain a date from a file and it is a DATE! what is in that date? for example I know it contains date/month, but can I get it to return the month as a string with a leading 0 or anything like that? Or is it up to me to code the formatting I need from integer date values? Is this documented anywhere or can I see any of the source some how. Thanks. |
BrianH 4-Jul-2009 [3126] | There are no built-in date formatting functions that do that. However, I'm sure the REBOL.org script library has one :) |
mhinson 4-Jul-2009 [3127] | Hi Brian, I see some goodies there. What I am doing is too trivial to want to link any large blocks of code just for that so I will just code the bit I need I think. I was puzzled because DATE returns the info with the month as a word, but date/month returns an integer, so I imagined there must me more to DATE! than just a structure containing integers? |
Ladislav 4-Jul-2009 [3128x2] | documented: do you mean like date/month date/day, etc? |
http://www.rebol.com/docs/core23/rebolcore-16.html#section-3.2 | |
mhinson 4-Jul-2009 [3130] | Hi Ladislav, yes. or any other bits of information attached to dtae types |
Ladislav 4-Jul-2009 [3131x3] | (I found a couple of errors in the text) |
seems, it was changed recently | |
the file http://www.rebol.com/r3/docs/datatypes/date.htmllooks like being affected too | |
Graham 4-Jul-2009 [3134x2] | >> d: now == 5-Jul-2009/10:36:09+12:00 >> d/1 == 2009 >> d/2 == 7 >> d/3 == 5 |
though it's 4th of July for you guys ... | |
Ladislav 4-Jul-2009 [3136] | not for me anymore |
mhinson 4-Jul-2009 [3137] | Thanks... I can work with that information, but I am curious as to how referencing the whole date gives Jul but there seems no option fot the month as a word.... not that I want it, but I am curious how that works. |
Ladislav 4-Jul-2009 [3138] | >> d: now == 5-Jul-2009/0:36:25+1:00 |
Graham 4-Jul-2009 [3139] | not applying to those guys who should be asleep! |
Ladislav 4-Jul-2009 [3140] | LOL |
Graham 4-Jul-2009 [3141] | which reminds me .. date functions should have a /utc refinement :) |
mhinson 4-Jul-2009 [3142] | I write my best code in the middle of the night with no PC... shame it is all forgotton by the morning, or written on toilet pater. |
Sunanda 4-Jul-2009 [3143] | Happy 753rd year of independence (source: wikipedia, apparently): http://www.theonion.com/content/node/50902 |
Graham 4-Jul-2009 [3144x2] | mhinson .. look at the locale |
753 years ??? | |
Sunanda 4-Jul-2009 [3146] | Check the article, graham. |
Graham 4-Jul-2009 [3147x2] | >> probe system/locale make object! [ months: [ "January" "February" "March" "April" "May" "June" "July" "August" "September" "October" "November" "December" ] days: [ "Monday" "Tuesday" "Wednesday" "Thursday" "Friday" "Saturday" "Sunday" ] ] |
Gavin Menzies, the english "historian" claims the americas were "discovered" by a chinese fleet in 1421 ... | |
Ladislav 4-Jul-2009 [3149] | >> d: now == 5-Jul-2009/0:42:01+2:00 >> pick system/locale/days d/weekday == "Sunday" >> pick system/locale/months d/month == "July" |
BrianH 4-Jul-2009 [3150] | Discovery means less and less every day :( |
Graham 4-Jul-2009 [3151x2] | I'll only trust wikipedia when they put the "a" back in ... as wikipaedia |
WTF ... did Ladislav's time zone undergo a shift ... or is he flying ?? | |
mhinson 4-Jul-2009 [3153] | so does Rebol always reference the system/locale when printing a DATE! but only store the inteeger values? or does it store the date in julian format & do more complex stuff to output even things like date/year |
Ladislav 4-Jul-2009 [3154] | graham: the first one was from R3, the second one from R2 |
Graham 4-Jul-2009 [3155] | oh ! |
Ladislav 4-Jul-2009 [3156] | so "flying from R3 to R2" |
Graham 4-Jul-2009 [3157] | In both cases .. your clock, or mine, is out by 2 mins |
BrianH 4-Jul-2009 [3158] | mhinson, MOLD and FORM never reference system/locale - REBOL syntax is English-based. |
