Generating .pdf files with batch?

Great, Steffen!

Thanks.

Thanks for your feedback, Saso!

For those of you guys who want to see the uncompressed human-readable code I'd like to add it to this thread, too.
Do not use it! It's ~25% slower for lines that contain tabs and still ~10% slower for files that don't contain tabs. ( rather use viewtopic.php?f=3&t=8289&start=15#p55139 )

einstein1969 posted a version which is both readable and fast. Thanks!

Wow! Great! Thanks to you both! Works great. Of course there is still a problem with our national characters. Steffen: do your umlaut letters for example get enconded successfully?

I've been never able to get around the limitation of supporting Windows-1252 only. That's kind of the default for PDF. I don't know how to get Unicode support, sorry.

Yes, PDF specification says that special characters should be embedded (fonts I think). Not easy to do.

Anyway. Einstein's solution is great, too.

Thanks.

This version on my system passed from 43sec to 11sec (4X)

I have insert the subs inline and changed the strlen into macro faster version

[einstein1969]

there is a very strange thing, you can check that you have more experience.

if I transform the tab_iter into this:

Code: Select all

set i=0
For /L %%. in (1,1,1250) do (
  if !i! lss !len! (
    set /a "nxt=!i!+1"
    for %%I in (!i!) do (
	if "!ln:~%%I,1!"=="%tab%" (
      		set /a "d=0-(%%I %% tabWidth)+tabWidth, e=nxt, nxt+=d-1, len+=d-1"
      		for /f "tokens=1,2" %%D in ("!d! !e!") do set "ln=!ln:~0,%%I!!spcs:~0,%%D!!ln:~%%E!"
        )
    )
    set /a i=nxt
  )
)

and I insert it in the block with the set / P (I avoid the CALL) the execution time of the batch doubles! I do not understand why'....

last version. I have inline strlen. Last code 8sec on my laptop

Code: Select all

short code
Elapsed 76 sec.
long code
Elapsed 96 sec.

I understand why: it is called thousands of times and actually did about 1000 * 1000 if useless

there was a wrong version in the zip I corrected and redid the tests. last version 10X

Code: Select all

short code
Elapsed 83 sec.
long code
Elapsed 95 sec.
einstein code
Elapsed 44 sec.
einstein code 2
Elapsed 15 sec.
long code (einstein latest)
Elapsed 11 sec.
long code (einstein latest 2)
Elapsed 9 sec.
long code (einstein latest 3)
Elapsed 8 sec.

I have made further progress.

I calculated the maximum expansion of the tabs and brought the tab_iter into the main loop. No more while..do / repeat..until loops
I have minimized the Sets and the calls to the strlen.
I have added comments

doubled the size of the txt, now it's 646KB.

Execution time dropped by 20% since last code. From 200 sec to 16 sec on my laptop. 13X

have a coffee during the tests ...

Code: Select all

short code
Elapsed 206.4 sec.
long code
Elapsed 222.9 sec.
einstein code
Elapsed 127.8 sec.

Code: Select all

einstein code 2
Elapsed 37.8 sec.
long code (einstein latest)
Elapsed 23.5 sec.
long code (einstein latest 2)
Elapsed 21.0 sec.
long code (einstein latest 3)
Elapsed 19.6 sec.
long code (einstein latest 4)
Elapsed 16.0 sec.

the fastest version is "txt2pdf_long5.bat"

Thanks! Will check.

In the mean time I checked the .pdf reference again. I still don't have a solution to embed a font (only characters I need) to the .pdf. Maybe one day.
