#-- Highlight the head position on the tape. I was really happy to have it and i made some test with 4K video on Youtube and the video looking great. We have the patron's and book's ID in variables and do double bookkeeping: When he returns the book, the process is reversed: The dueback field (%Y-%M-%d format is good for sorting and comparing) is useful for checking whether books have not been returned in time: Likewise, parts of the accounting (e.g. So 8 is the associated integer of a&&b, but not only of this — we get the same integer for ! For such few values it is most efficient to just look them up in a pre-built table, as Tcllib's math::factorial does. Because so many people want that bright, over saturated, cold as ice, picture. Why TCL 65R625 should be your choice? Let us write a simple Tcl program. I won't go into all details of the above code, just some: (<.,>.) If a field content contains spaces, it must be quoted or braced too: Sorting a table can be done with lsort -index, taking care that the header line stays on top: Removing a row (or contiguous sequence of rows) by numeric index is a job for lreplace: Simple printing of such a table, a row per line, is easy with. In Europe and elsewhere, the most widely used paper format is called A4. Developer Tools. What's missing is the capability to randomly address parts of a stream, as is possible in Scheme (and of course their claim to do without assignment, or mutable data...) Tcl lists just don't follow LISP's CAR/CDR model (though KBK demonstrated in Tcl and LISP that this structure can be emulated, also with procs), but rather C's flat *TclObject[] style. For instance, if the test has two inputs and wants one output, the stack balance is -1 (one less out than in). The TCL 6-Series' 2019 number is basically the same as the 2019 Vizio M8 and better than the Samsung Q70R, if you're keeping score.The above applies to HDR10 only; I didn't measure Dolby Vision. Maybe you need to get your eyes checked, but if you’re comparing it to the vivid or normal modes, of course it’s going to look more yellow, bc it’s defaulted to warm color temp, which is correct. Though slick at first sight, we actually have to type more. Do not use solvents or abrasive detergents to clean the coffee maker. It delivered the best combination of light output and black level, and stayed admirably close to the target EOTF -- something few of the other modes, including Darker/Dark HDR, could muster. My "Def" creates an interp alias, which is a good and simple Tcl way to compose partial scripts (the definition, here) with one or more arguments, also known as "currying": The second parameter, "=", is for better looks only and evidently never used. As you see below, many functionalities can be "implemented" by just using Tcl's list functions. I added converters between characters and integers, and between strings and lists (see the dictionary below). The task is to conclude something from the following premises: These are encoded to the following one-letter predicates: So the problem set can be restated, in Spencer-Brown's terms, as. Text Editor 2. The Python 64-bit/32-bit Mac OS X installers for Python 3.6.x, 3.5.x, and 2.7.x dynamically link to Tcl/Tk 8.5 frameworks. Getting more daring, let's try a distributive law: Daring more: what if we postulate the equivalence? priority queue is any of the more clever ways: A*, Greedy, ... builds up a nest of foreachs suiting the problem, quick kills (with continue) to force unique values for the variables, and. The most important reason people chose Python is: Python's popularity and beginner friendliness has led to a wealth of tutorials and example code on the internet. Review:TCL 65R625Related products:TCL 55R625Calibration report:[see below]TV software/firmware version tested: version 9.1.2, build 6121Picture settings tested: CNET is no longer publishing advanced picture settings for TVs we review. We recommend leaving this setting off, but if you find lower framerate content looks choppy (stutter), you can enable it, in which case the TV will interpolate extra frames to increase the framerate up to 60 Hz. Alot of football during the fall. The show interfaces command has been executed from Tcl configuration mode.. Router# tclsh Router(tcl)# exec "show interfaces" Ethernet 0 is up, line protocol is up Hardware is MCI Ethernet, address is 0000.0c00.750c (bia 0000.0c00.750c) Internet address is, subnet … Classes in C++ started out as structs, so I take a minimal struct as example, with generic get and set methods. Of course, there are some who say: "Advocating object-orientated programming is like advocating pants-oriented clothing: it covers your behind, but often doesn't fit best" ... Quite a bunch of what is called OO can be done in pure Tcl without a "framework", only that the code might look clumsy and distracting. Functions in Tcl are typically written with the proc command. All the rest would be there. A simpler example is pipes in Unix/DOS (use TYPE for cat there): where the "cat" delivers lines of the file as long as "more" will take them, and waits otherwise (after all, stdin and stdout are just streams...). I'm far from having digested it all, but like so often, interesting reading prompts me to do Tcl experiments, especially on weekends. Interface and language bindings to Tcl/Tk GUI elements. 123f.). Oct-18-2017, 09:09 AM . Streams in general should not be written in brackets (then the Tcl parser would eagerly evaluate them before evaluating the command), but braced, and stream consumers eval the stream at their discretion. TCL 65R615 comes as the middle one. Tcl/Tk for EDA Every user of EDA tools and hardware description languages such as VHDL and Verilog needs to know about Tcl! #-- We need basic scalar operators from expr factored out: "length mismatch [llength $a] != [llength $b]". In J, it looks like this: which may better explain why I wouldn't want to code in J :^) J has ASCIIfied the zoo of APL strange character operators, at the cost of using braces and brackets as operators too, without regard for balancing, and extending them with dots and colons, so e.g. The cute name "e.g." _tkinter finds tcl/tk installed with Python at its known location for … # Here is another stream producer that returns elements from a list: # This one repeats its list endlessly, so better use it with 'more': # This is sugar for first-time assignment of static variables: # But for a simple constant stream source, just use [subst]: # more {subst 1} ;# will produce as many ones as you wish. But it looks halfway like the real thing: you get sort of an assembly listing with symbol table, and can run it — I'd hardly start writing an assembler in C, but in Tcl it's fun for a sunny Sunday afternoon... }, The mov b,INCR part is an oversimplification. Tcl_Main - main program, startup script, and event loop definition for Tcl-based applications; Tcl_AppInit - perform application-specific initialization; Tcl_FindExecutable - identify or return the name of the binary file containing the application; Tcl_CreateInterp - create and delete Tcl command interpreters Luckily we have an if in Tcl (and it certainly fares better in byte-code compilation), but on leisurely evenings it's not the microseconds that count (for me at least) — it's rather reading on the most surprising (or fundamental) ideas, and demonstrating how easily Tcl can bring them to life... Never afraid of anything (as long as everything is a string), a discussion in the Tcl chatroom brought me to try the following: let the computer write ("discover") its own software, only given specifications of input and output. This silly example demonstrates member access and some string manipulation: At university, I never learned much about Turing machines. Joined: Oct 2017. For instance, here's a breathtakingly short J program to compute the mean of a list of numbers: Only implicitly present is a powerful function combinator called "fork". ErikFrisk Unladen Swallow. Programming Languages. The Tcl/Tk documentation is in the system man pages. It has better local dimming but no more zones and better colour. The "runtime engine" is just called "r" (not to be confused with the R language), and it boils down to a three-way switch done for each word, in eleven lines of code: Joy's rich quoting for types ([list], {set}, "string", 'char) conflict with the Tcl parser, so lists in "r" are {braced} if their length isn't 1, and (parenthesized) if it is — but the word shall not be evaluated now. Note that with this mapping, all valid programs (bytecode sequences) correspond to one unique non-negative integer, and longer programs have higher integers associated: Now out for discovery! This way, a stream can promise to be a potentially endless source of data, while taking only finite time to process and deliver what's really wanted. That's all. Transparent OO for Tcl, or TOOT for short, is a very amazing combination of Tcl's concept of transparent values, and the power of OO concepts. The special item "" (the empty string) indicates that the stream is exhausted. Say you want to make a multiplication table for an elementary school kid near you. During the substitution phase of command evaluation, the two grouping operators, the brace ({) and the double quote ("), are treated differently by the Tcl interpreter. All Tcl files will have an extension, i.e., .tcl. so the two-way If is about as mighty as the real thing, give or take a few braces and redundant keywords (then, else). So here is one model of a state machine in ten lines of code. which is shorter and simpler, but meddles more directly with the stack. (Comm. # predecessor function, when for integers. Retrieving a record is as easy as this (though the fields come in undefined order): and deleting a record is only slightly more convolved: or, even easier and faster from Tcl 8.3 on: Here's how to get a "column", all fields of a given tag: But real columns may have empty fields, which we don't want to store. And formatMatrix and outProd are so general that one might include them in some library, while the task of producing a multiplication table may not come up any more for a long time... Tcl follows strictly the Polish notation, where an operator or function always precedes its arguments. execution of the script "++" should sum its three arguments (1+(2+3)), and return 6. fractions, can be thought of as pairs of integers {numerator denominator}, such that their "real" numerical value is numerator/denominator (and not in integer nor "double" division!). ", as it might also stand for factorial — and see the shortest function body I ever wrote :^) : Without big mention, functions implemented by recursion have a pattern for which func is well suited (see fac and gcd above). For functional composition, where, say for two functions f and g. again a proc is created that does the bracket nesting: Why Backus used Transpose on the input, wasn't first clear to me, but as he (like we Tclers) represents a matrix as a list of rows, which are again lists (also known as vectors), it later made much sense to me. For recursive functions and other arithmetics, func makes better reading, by accepting expr language in the body: We'll use this to turn expr's infix operators into dyadic functions, plus the "slashdot" operator that makes division always return a real number, hence the dot : For "fold", this time I devised a recursive version: Tacit enough (one might have picked fancier names like +/ for "sum" and # as alias for llength), but in principle it is equivalent to the J version, and doesn't name a single argument. Using the Tcl shell to run CLI commands allows users to to automate repetitive tasks, and to create custom output for show commands. We can call TCL 65R625 is the new model of TCL 65R615. Here's typical set operations. Dark room settings:TV brightness: DarkerPicture mode: Movie*Picture size: AutoAdvanced picture settings:Picture mode: Movie*Local contrast: HighDynamic Contrast: Off [grayed out]Backlight: 56Brightness: 50Contrast: 90Sharpness: 0Color: 45Tint: 0Color Temperature: WarmAction Smoothing: OffNatural Cinema: OnLED Motion Clarity: OffGame mode: OffRoku app Settings/Expert picture settings menu:Picture mode: Movie*Gamma: 2.0Noise reduction: OffBright room settings:TV Brightness: BrighterPicture mode: MoviePicture size: Auto[no other adjustments on-screen or in app]HDR notes: Just like with SDR TCL offers different HDR settings tailored to room brightness, but their names can be a bit misleading. Posts: 4. A good working knowledge of Tcl can help you gain greater productivity in using EDA tools for FPGA and ASIC design, but many Tcl courses and textbooks focus on using Tcl for general-purpose computing applications. To make things easier, this flavor of "software" is in a very simple RPN language similar to, but much smaller than, the one presented in Playing bytecode: stack-oriented like Forth, each operation being one byte (ASCII char) wide, so we don't even need whitespace in between. To add this bundle*, enter: sudo swupd bundle-add python3-tcl. Here is a simple example of a "chat bot" — a program that listens on an IRC chatroom, and sometimes also says something, according to its programming. "{usage: $procname [uplevel 1 [list info args $procname]]}", # This comment should not appear in the docstring, # Signature of a proc: arguments with defaults, # fall back to standard queue, now that it's sorted, "foreach $var \$domain[expr [lsearch $initials $var]>=0] \{\n", "if {\[expr $test\]} {return \[subst $test\]}", "[db'get db $id author]: [db'get db $id title] $db($i)", "please return $db($book,title) which was due on\, "[db'get db $id title] - [db'get db $id label]". This package provides access to the platform-independent Tcl scripting language and Tk GUI elements. What settings would you suggest so I get the best picture. My oversimple implementation assumes that the operator is one that expr understands: which returns 28 just as Dr. Backus ordered (= 1*6 + 2*5 + 3*4). The TCL P607 p series is a very good HDR TV with better than average picture quality thanks to its deep blacks. This is provided e.g. The ART design of combining metallic casing and super narrow bezel makes this product not just a TV, but a beautiful artwork for your living room. I’d take the 75” older model because there isn’t much of an advantage for this years model. Tcl doesn't have this mechanism built-in (and it would be hard to do it exactly the same way, because everything is a string), but a similar mechanism can easily be adopted, and it doesn't look bad in comparison: Common Lisp: (documentation 'foo 'function) Python: foo.__doc__; Tcl: docstring foo My only gripe is that the adjustment for 10% didn't have much effect and ended up pushing color into less-accurate territory after I ventured into the extreme parts of the range, so I ended up leaving it zeroed out. A more generic filter takes a condition and a stream, and on each call returns an element of the input stream where the condition holds — if ever one comes along: Friends of syntactic sugar might prefer shell style: and guess what, we can have that in Tcl too (and not in Scheme !-), by writing a proc, that also resets all sprocs, with the fancy name "$" (in Unix, this could be the shell prompt that you don't type, but for Tcl we always have to have the command name as first word): To prove that we haven't cheated by using exec, let's introduce a line counter filter: This can be added to filter chains, to count lines in the original file, or only the results from grep: We further observe that more has a similar structure to filter, so we could also rewrite it in terms of that: The sort filter is unusual in that it consumes its whole (finite!) The TCL 6-Series' 2019 number is basically the same as the 2019 Vizio M8 and better than the Samsung Q70R, if you're keeping score. Also, memory limits on modern computers are somewhere up high... so only at some time in the future you might have (but maybe not want) to change to a complex database ;-). Delivers immersive 5.1 surround sound with Dolby decoder which optimizes the TV’s sound quality. After a while on color accurate setting the oversaturated store demo settings will not be appealing, just like cutting out excessive sugar in your diet. TCL 65R625 and 65R615 are both introduced as TCL’s 65-Inch 6-Series 4K UHD TV. In a frequent parlage, priority 1 is the "highest", and the number increases for "lower" priorities — but you could push in an item with 0 for "ultrahigh" ;-) Popping a stack can be done like this: Popping a queue is similarly structured, but with so different details that I found no convenient way to factor out things: Popping a priority queue requires sorting out which item has highest priority. Accessing fields in a table is more fun with the field names than the numeric indexes, which is made easy by the fact that the field names are in the first row: Here is how to filter a table by giving pairs of field name and glob-style expression — in addition to the header line, all rows that satisfy at least one of those come through (you can force AND behavior by just nesting such calls): This filters (and, if wanted, rearranges) columns, sort of what is called a "view": In the following few chapters you'll see how easy it is to emulate or explore other programming languages with Tcl. First lmap is a collecting foreach — it maps the specified body over a list: The following generic wrapper takes one binary operator (could be any suitable function) and two arguments, which may be scalars, vectors, or even matrices (lists of lists), as it recurses as often as needed. Testing: a tiny state machine that greets you as often as you wish, and ends if you only hit Return on the "how often?" This is something like the Goedel number of the corresponding code. Rather, one could use read and write traces on variable M, causing it to load from, or store to, mem($HL). I started with Backus' first Functional Program example. You say bigger is better, but what would you choose between a 2018 75 inch 6 series vs a 2019 65 inch 6 series? The main site for Tcl/Tk source distributions is SourceForge. to make it understand and do things that before raised an error, the easiest way is to write a proc. Doing more steps towards functional programming, I came upon this interesting problem, and will shortly demonstrate that it can easily be solved in pure-Tcl. One point that was new for me is that the distinction between operators and operands is not cast in stone. I rather wanted to explore some of these concepts and how to use them in Tcl, so that in slightly more verbose words I could code (and call). Reputation: 0 #1. From the Advanced Picture Settings menu, we recommend setting contrast to '100', brightness to '50', and sharpness to '20'. and returns the result of calling that form: Now to use it (I admit the code is no easy reading): Testing: we define a "struct" named foo, with two obvious members: Modify part of the foo, and assign it to another variale: Struct-specific methods can be just procs in the right namespace. Clean the filter holder, filters, drip tray and water tank regularly. If they don't, we have found a fact that isn't dependent on the variable's value, and the resulting constant is returned, otherwise the unsolved expression: with a helper function in that reports containment of an element in a list: which means, in expr terms, {(!$a || $a) == 1}, for all values of a. Another example is this integer range generator (starts from 1, and is inclusive, so [iota1 5] == {1 2 3 4 5}): "NAND is not AND." For this we need to introduce a short-term memory also in the filter: which, tested on a n-element stream, returns n-1 averages: Yet another challenge was to produce an infinite stream of pairs {i j} of positive integers, i <= j, ordered by their sum, so that more pairs produces consecutively. On the other hand, the present approach is pretty economic, since it does not use field widths (all strings are "shrink-wrapped"), and omits empty fields, while at the same time allowing to add whatever fields you wish. I measured all three of the local dimming settings (called "Local Contrast" in the menu) and High, the default for Movie, delivered the deepest black levels and the best gamma for my lighting environment.Grayscale accuracy out of the box was solid, although my review sample was a bit minus-green. It is used to avoid same code being repeated in m If composite functions like 'fork' are arguments to o*, we'd better let unknown know that we want auto-expansion of first word: Also, we need a numeric sort that's good for integers as well as reals ("Def" serves for all kinds of aliases, not just combinations of functions): As this file gets tacitly sourced, I am pretty confident that I've reached my goal for this weekend — even though my median doesn't remotely look like the J version: it is as "wordy" as Tcl usually is. Filters may be characterized as "selectors" (who may return only part of their input, like "grep") and/or "appliers" who call a command on their input and return the result. Here, pushing has to be done by dedicated code because a previous instance would have to be removed: The first element is the least recently, the last the most recently used. The storage for the array of bytes is owned by the value and should not be freed. Notice that so far we have only defined one short proc, all other operations were done with built-in Tcl commands only. In the last lesson you saw that grouping words with double quotes allows substitutions to occur within the double quotes. is a popular function with super-exponential growth. following Backus' FP language with the "Def" command. But func isn't limited to math functions (which, especially when recursive, come out nice), but for expr uses in testing predicates as well: Exposing expr binary arithmetic operators as Tcl commands goes quite easy too: For "-", we distinguish unary and binary form: Having the modulo operator exposed, gcd now looks nicer: For unary not I prefer that name to "! Okay first off, you need to realize that the movie setting is targeting the D65 White point. To search for bundles and their contents, enter: swupd search python3-tcl. To empty the drip tray, extract the cup tray grill, remove the water and clean the tray with a cloth and then reassemble the drip tray. 4.6 out of 5 stars 868. "Tacit programming" (tacit: implied; indicated by necessary connotation though not expressed directly) is one of the styles possible in J, and means coding by combining functions, without reference to argument names. Note that +/ is considered one operator, which applies the "adverb" folding to the "verb" addition (one might well call it "sum"). In TOOT, the values of objects are represented as a list of length 3: the class name (so much for "runtime type information" :-), a "|" as separator and indicator, and the values of the object, e.g. For easier handling, it's a good idea to classify records somehow (we'll want to store more than books), so we add. one with at most one rule per state and input character), which gives clear instructions and two test cases for input and output, so I decided to try my hand in Tcl.
