how to lsearch in list always match - tcl

I want match search from a list. I have dir names example:
blabla.aa
cc.oiwerwer
asfd.Dd.asoiwer
and I want to check if it is in the list (upper case should be ignored).
bind pub "-|-" !tt tt
proc tt {nick host handle channel arg} {
set name [lindex [split $arg] 0]
set groups {aa BB Cc DD Ee Ff gg hh}
if {[lsearch -inline $groups $name] != -1} {
putnow "PRIVMSG $channel :match name $name"
}
}
No matter what I write, it always says match...
Regards

If I understood correctly, you want to know if any element of the list groups matches the dir name examples. If that's so, then you should use a loop with string match:
bind pub "-|-" !tt tt
proc tt {nick host handle channel arg} {
set name [lindex [split $arg] 0]
set groups {aa BB Cc DD Ee Ff gg hh}
foreach group $groups {
if {[string match -nocase *$group* $name]} {
putnow "PRIVMSG $channel :$name matched $group"
break
}
}
}

You specified the "-inline" parameter to lsearch. It returns the match or empty string. So, it is always doesn't equal to -1. Try to remove the "-inline" parameter. Also, probably you want to use the "-exact" parameter.
Reference: https://www.tcl.tk/man/tcl8.6/TclCmd/lsearch.htm

If you can arrange for your list of things to be all in one case (e.g., lower case) then you can use [string tolower] and the in operator to do the search. This is simpler than lsearch as it produces a clean binary result:
proc tt {nick host handle channel arg} {
set name [lindex [split $arg] 0]
set groups {aa bb cc dd ee ff gg hh}
if {[string tolower $name] in $groups} {
putnow "PRIVMSG $channel :match name $name"
}
}

Your question is a bit unclear, but piecing together some clues, you might want:
set channels {
blabla.aa
cc.oiwerwer
asfd.Dd.asoiwer
}
set groups {aa BB Cc DD Ee Ff gg hh}
foreach group $groups {
set idx [lsearch -nocase $channels "*$group*"]
if {$idx != -1} {
puts "$group -> [lindex $channels $idx]"
}
}
which outputs
aa -> blabla.aa
Cc -> cc.oiwerwer
DD -> asfd.Dd.asoiwer
Or, much more terse is:
lsearch -inline -all -nocase -regexp $channels [join $groups |]
blabla.aa cc.oiwerwer asfd.Dd.asoiwer

how to split a file to list of lists TCL

I'm coding TCL and I would like to split a file into two lists of lists,
the file contain:
(1,2) (3,4) (5,6)
(7,8) (9,10) (11,12)
and I would like to get two list
one for each line, that contain lists that each one contain to two number
for example:
puts $list1 #-> {1 2} {3 4} {5 6}
puts [lindex $list1 0] #-> 1 2
puts [lindex $list2 2] #-> 11 12
I tried to use regexp and split but no success
The idea of using regexp is good, but you'll need to do some post-processing on its output.
# This is what you'd read from a file
set inputdata "(1,2) (3,4) (5,6)\n(7,8) (9,10) (11,12)\n"
foreach line [split $inputdata "\n"] {
# Skip empty lines.
# (I often put a comment format in my data files too; this is where I'd handle it.)
if {$line eq ""} continue
# Parse the line.
set bits [regexp -all -inline {\(\s*(\d+)\s*,\s*(\d+)\s*\)} $line]
# Example results of regexp:
# (1,2) 1 2 (3,4) 3 4 (5,6) 5 6
# Post-process to build the lists you really want
set list([incr idx]) [lmap {- a b} $bits {list $a $b}]
}
Note that this is building up an array; long experience says that calling variables list1, list2, …, when you're building them in a loop is a bad idea, and that an array should be used, effectively giving variables like list(1), list(2), …, as that yields a much lower bug rate.
An alternate approach is to use a simpler regexp and then have scan parse the results. This can be more effective when the numbers aren't just digit strings.
foreach line [split $inputdata "\n"] {
if {$line eq ""} continue
set bits [regexp -all -inline {\([^()]+\)} $line]
set list([incr idx]) [lmap substr $bits {scan $substr "(%d,%d)"}]
}
If you're not using Tcl 8.6, you won't have lmap yet. In that case you'd do something like this instead:
foreach line [split $inputdata "\n"] {
if {$line eq ""} continue
set bits [regexp -all -inline {\(\s*(\d+)\s*,\s*(\d+)\s*\)} $line]
set list([incr idx]) {}
foreach {- a b} $bits {
lappend list($idx) [list $a b]
}
}
foreach line [split $inputdata "\n"] {
if {$line eq ""} continue
set bits [regexp -all -inline {\([^()]+\)} $line]
set list([incr idx]) {}
foreach substr $bits {
lappend list($idx) [scan $substr "(%d,%d)"]
# In *very* old Tcl you'd need this:
# scan $substr "(%d,%d)" a b
# lappend list($idx) [list $a $b]
}
}
You have an answer already, but it can actually be done a little bit simpler (or at least without regexp, which is usually a good thing).
Like Donal, I'll assume this to be the text read from a file:
set lines "(1,2) (3,4) (5,6)\n(7,8) (9,10) (11,12)\n"
Clean it up a bit, removing the parentheses and any white space before and after the data:
% set lines [string map {( {} ) {}} [string trim $lines]]
1,2 3,4 5,6
7,8 9,10 11,12
One way to do it with good old-fashioned Tcl, resulting in a cluster of variables named lineN, where N is an integer 1, 2, 3...:
set idx 0
foreach lin [split $lines \n] {
set res {}
foreach li [split $lin] {
lappend res [split $li ,]
}
set line[incr idx] $res
}
A doubly iterative structure like this (a number of lines, each having a number of pairs of numbers separated by a single comma) is easy to process using one foreach within the other. The variable res is used for storing result lines as they are assembled. At the innermost level, the pairs are split and list-appended to the result. For each completed line, a variable is created to store the result: its name consists of the string "line" and an increasing index.
As Donal says, it's not a good idea to use clusters of variables. It's much better to collect them into an array (same code, except for how the result variable is named):
set idx 0
foreach lin [split $lines \n] {
set res {}
foreach li [split $lin] {
lappend res [split $li ,]
}
set line([incr idx]) $res
}
If you have the results in an array, you can use the parray utility command to list them in one fell swoop:
% parray line
line(1) = {1 2} {3 4} {5 6}
line(2) = {7 8} {9 10} {11 12}
(Note that this is printed output, not a function return value.)
You can get whole lines from this result:
% set line(1)
{1 2} {3 4} {5 6}
Or you can access pairs:
% lindex $line(1) 0
1 2
% lindex $line(2) 2
11 12
If you have the lmap command (or the replacement linked to below), you can simplify the solution somewhat (you don't need the res variable):
set idx 0
foreach lin [split $lines \n] {
set line([incr idx]) [lmap li [split $lin] {
split $li ,
}]
}
Still simpler is to let the result be a nested list:
set lineList [lmap lin [split $lines \n] {
lmap li [split $lin] {
split $li ,
}
}]
You can access parts of the result similar to above:
% lindex $lineList 0
{1 2} {3 4} {5 6}
% lindex $lineList 0 0
1 2
% lindex $lineList 1 2
11 12

The code works for windows :
TCL file code is :
proc captureImage {} {
#open the image config file.
set configFile [open "C:/main/image_config.txt" r]
#To retrive the values from the config file.
while {![eof $configFile]} {
set part [split [gets $configFile] "="]
set props([string trimright [lindex $part 0]]) [string trimleft [lindex $part 1]]
}
close $configFile
set time [clock format [clock seconds] -format %Y%m%d_%H%M%S]
set date [clock format [clock seconds] -format %Y%m%d]
#create the folder with the current date
set folderPath $props(folderPath)
append folderDate $folderPath "" $date "/"
set FolderCreation [file mkdir $folderDate]
while {0} {
if { [file exists $date] == 1} {
}
break
}
#camera selection to capture image.
set camera "video"
append cctv $camera "=" $props(cctv)
#set the image resolution (XxY).
set resolutionX $props(resolutionX)
set resolutionY $props(resolutionY)
append resolution $resolutionX "x" $resolutionY
#set the name to the save image
set imagePrefix $props(imagePrefix)
set imageFormat $props(imageFormat)
append filename $folderDate "" $imagePrefix "_" $time "." $imageFormat
set logPrefix "Image_log"
append logFile $folderDate "" $logPrefix "" $date ".txt"
#ffmpeg command to capture image in background
exec ffmpeg -f dshow -benchmark -i $cctv -s $resolution $filename >& $logFile &
after 3000
}
}
captureImage
thext file code is :
cctv=Integrated Webcam
resolutionX=1920
resolutionY=1080
imagePrefix=ImageCapture
imageFormat=jpg
folderPath=c:/test/
//camera=video=Integrated Webcam,Logitech HD Webcam C525
This code works for me me accept the code from text file were list of parameters are passed.

How to compare two lines in different files and output the same position in the other line in TCL?

I have two files and I want the output like below. Please help by providing me with a TCL script.
File1:
Name1: F * F F F
Name2: F F *
Name3: F F F F
File2:
Name1: AA, BB, CC, DD, EE,
Name2: AA, BB, CC,
Name3: AA, BB, CC, DD,
Output1:
Name1
AA - FAIL
BB - *
CC - FAIL
<cont>
Name2
AA - FAIL
BB - FAIL
CC - *
<cont>
Output2:
Name1
FAIL - AA CC DD EE
* - BB
Name2
FAIL - AA BB
* - CC
Name3
FAIL - AA BB CC DD
Try this following tested on tclsh8.5
set fd1 [open "input_file_1.txt" r]
set fd2 [open "input_file_2.txt" r]
set opfd [open "output_file.txt" w]
while {[gets $fd1 line] > 0 && [gets $fd2 line2] > 0} {
set line1 [split $line ":"]
set line2 [split $line2 ":"]
puts $opfd [lindex $line1 0]
set last_part_1 [string trim [lindex $line1 1] " "]
set last_part_2 [string trim [lindex $line2 1] " "]
set space_split [split $last_part_1 " "]
set comma_split [split $last_part_2 ","]
for {set i 0} {$i < [llength $space_split]} {incr i} {
puts $opfd "[string trim [lindex $comma_split $i] " "] = [string trim [lindex $space_split $i] " "]"
}
}
close $fd1
close $fd2
close $opfd
There will be file named as output_file.txt created inside current directory which contains your output.
Another way to do it:
package require fileutil
proc getInput filename {
set contents [string trim [::fileutil::cat $filename]]
set rows [split $contents \n]
concat {*}[lmap item $rows {
split $item :
}]
}
set d1 [string map {F Fail} [getInput file1.txt]]
set d2 [string map {, {}} [getInput file2.txt]]
dict for {key values} $d1 {
puts $key
foreach v1 $values v2 [dict get $d2 $key] {
puts " $v2 - $v1"
}
}
This works by recognizing the dictionary-like structure of the data files. If every piece of data is a word without spaces, this version of getInput will coerce the contents of each file to a usable dict. From there, it's just a matter of replacing the F strings with Fail strings and removing the commas, and then doing dictionary iteration over either one of the dicts and pulling in the corresponding values from the other one.
If the values in the second file may contain spaces, getInput should look like this:
proc getInput filename {
set contents [string trim [::fileutil::cat $filename]]
set rows [split $contents \n]
set res {}
foreach item $rows {
lassign [split $item :] key values
if {[string match *,* $values]} {
set values [split [string trimright $values {, }] ,]
}
lappend res $key $values
}
return $res
}

Print array key = value with colon separating

I suspect there is a one liner that takes an array into a string which looks like x=1;y=2;z=3. How can I do that? I am currently using
set vals [join [array names a] \;]
to get x;y;z but would like the values in there. If there happens not to be a value, I would like to skip the = sign, e.g., x=1;y;z=3. Maybe with array get?
This gets all the info in there, but the result looks like x;1;y;2;z;3;q;3
set vals [join [array get a] \;]
some how I'm thinking there is a slice we can take here
Update. Yes, I know that you could do a foreach, but I wonder if there is a one-liner. For example this seems to work
foreach { k v } [array get a] {
if {$v ne ""} {
lappend valList $k=$v
} else {
lappend valList $k
}
}
set vals [join $valList \;]
join [lmap {k v} [array get a] {if {$v ne {}} {join [list $k $v] =} {set k}}] \;
If your Tcl doesn't have lmap, there's a handy replacement.

TCL String Manipulation and Extraction

I have a string xxxxxxx-s12345ab7_0_0_xx2.log and need to have an output like AB700_xx2 in TCL.
ab will be the delimiter and need to extract from ab to . (including ab) and also have to remove only the first two underscores.
Tried string trim, string trimleft and string trimright, but not much use. Is there anything like string split in TCL?
The first stage is to extract the basic relevant substring; the easiest way to do that is actually with a regular expression:
set inputString "xxxxxxx-s12345ab7_0_0_xx2.log"
if {![regexp {ab[^.]+} $inputString extracted]} {
error "didn't match!"
}
puts "got $extracted"
# ===> got ab7_0_0_xx2
Then, we want to get rid of those nasty underscores with string map:
set final [string map {"_" ""} $extracted]
puts "got $final"
# ===> ab700xx2
Hmm, not quite what we wanted! We wanted to keep the last underscore and to up-case the first part.
set pieces [split $extracted "_"]
set final [string toupper [join [lrange $pieces 0 2] ""]]_[join [lrange $pieces 3 end] "_"]
puts "got $final"
# ===> got AB700_xx2
(The split command divides a string up into “records” by an optional record specifier — which defaults to any whitespace character — that we can then manipulate easily with list operations. The join command does the reverse, but here I'm using an empty record specifier on one half which makes everything be concatenated. I think you can guess what the string toupper and lrange commands do…)
set a "xxxxxxx-s12345ab7_0_0_xx2.log"
set a [split $a ""]
set trig 0
set extract ""
for {set i 0} {$i < [llength $a]} {incr i} {
if {"ab" eq "[lindex $a $i][lindex $a [expr $i+1]]"} {
set trig 1
}
if {$trig == 1} {
append extract [lindex $a $i]
}
}
set extract "[string toupper [join [lrange [split [lindex [split $extract .] 0] _] 0 end-1] ""]]_[lindex [split [lindex [split $extract .] 0] _] end]"
puts $extract
Only regexp is enough to do the trick.
Set string "xxxxxxx-s12345ab7_0_0_xx2.log"
regexp {(ab)(.*)_(.*)_(.*)_(.*)\\.} $string -> s1 s2 s3 s4 s5
Set rstring "$s1$s2$s3$s4\_$s5"
Puts $rstring

TCL Program that Compare String

I'm trying to create a program that the First and last characters are compared, Second and second to the last are compared, Third and third to the last are compared, and so on, and if any of these characters match, the two will be converted to the uppercase of that character.
Example:
Please enter a text: Hello Philippines
finals: HEllo PhIlippinEs
I can't create any piece of code, I'm stuck with
puts "Please enter text:"
set myText [gets stdin]
string index $myText 4
Can someone help me please?
This procedure will also capitalize the first i in Phillipines because it's equidistant from the start and the end of the string.
proc compare_chars {str} {
set letters [split $str ""]
for {set i [expr {[llength $letters] / 2}]} {$i >= 0} {incr i -1} {
set a [lindex $letters $i]
set b [lindex $letters end-$i]
if {$a eq $b} {
lset letters $i [set L [string toupper $a]]
lset letters end-$i $L
}
}
join $letters ""
}
puts [compare_chars "Hello Phillipines"]
# outputs => HEllo PhIllipinEs
The simplest way to code this is to use foreach over the split-up characters. (It's formally not the most efficient, but it's very easy to code correctly.)
puts "Please enter text:"
set myText [gets stdin]
set chars [split $myText ""]
set idx 0
foreach a $chars b [lreverse $chars] {
if {[string equals -nocase $a $b]} {
lset chars $idx [string toupper $a]
}
incr idx
}
set output [join $chars ""]
puts $output
Note that the foreach is iterating over a copy of the list; there are no problems with concurrent modification. In fact, the only vaguely-tricky part from a coding perspective is actually that we need to keep track of the index to modify, in the idx variable above.
With Tcl 8.6 you could write:
set chars [split $myText ""]
set output [join [lmap a $chars b [lreverse $chars] {
expr {[string equals -nocase $a $b] ? [string toupper $a] : $a}
}] ""]
That does depend on having the new lmap command though.
If you're really stuck with 8.3 (it's unsupported and has been so for years, so you should be prioritizing upgrading to something more recent) then try this:
set chars [split $myText ""]
set idx [llength $chars]
set output {}
foreach ch $chars {
if {[string equals -nocase $ch [lindex $chars [incr idx -1]]]} {
append output [string toupper $ch]
} else {
append output [string tolower $ch]
}
}
All the features this uses were present in 8.3 (though some were considerably slower than in later versions).
