2013/07/18 v0.99.26
- A bug in confmgr.c caused errors when reading strings from
the configuration (thanks Graham Inggs)
2013/01/09 v0.99.25
- A rather important bug infiltrated when changeing the
configuration system. Though I carefully prepared the
default values for the vector map, I entered them in hex
which them caused a white chart.
If you had/have this problem, the easiest way out is to
use this new version, but first deleting the previous
configuration file (in your home directory .gnome2/linsmith)
- To encourage the use of the vector chart anyway, it is
now the default for new installs.
2012/12/04 v0.99.24
- Print bug correct (Segfault on second call to print).
(Thanks for reporting, Clyde!)
- Cleanups in the configuration load/save functions
2011/03/21 v0.99.22
- Change papersize_combo to combobox, and load the list from
the available papersizes.
- Adapted confmgr to accept char * from comboboxes.
- Moving down elements caused a segfault, because of wrongly
g_free'ing an iter. (Thanks clydes!)
- Moving elements up implemented.
- A crash in the configuration dialog fixed, which made it
impossible to save the SWR circle color. (Thanks clydes!)
- Converted the strange negative default values for the color
definitions to their (easier to understand?) hex values.
- The 'standard cable' code mostly re-written, and a few
more cable types added.
2011/03/20 v0.99.21
- Removed the (deprecated) gnomeprint depency.
Now the complete print route relies on Pango/Cairo to
generate the plot, and the GtkPrint interface to do the actual
printing. (After some poking from Thomas Beierlein, from gentoo.
Thanks)
2010/05/14 v0.99.20
- Slight improvements to the vector plot.
- Better (?) default values for colors of plot.
- Modified the confmgr to accept hex and octal values in the
configuration file.
2009/05/08 v0.99.12
- Missing NULL in run_filedialog caused warnings when saving
the log. In some cases it could cause segmentation faults too.
Thanks to the guys at Fedora for notifying me!
2008/09/02 v0.99.11
- Swedish translation updated (Thanks Peter!)
- Smaller bugs corrected which could cause a few problems if
z0 was changed. (chart.c - Thanks for the indications, Anatoly!)
2008/08/22 v0.99.10
- The last s2p file's name is now saved in the configuration.
Had forgotten that in the previous version.
2008/08/21 v0.99.9
- Added import of Touchstone(r) two-port files. Until now, only
Version 1.0 files are correctly parsed, though completely (I
hope) with all parameter types, and input formats.
- Spanish translation has been updated.
- Manual has been updated with this info.
2008/05/26 v0.99.7
- Dustin Vaselaar reports problems inputing loads. 'errno' is
now cleared before each strtod call.
2008/04/25 v0.99.6
- Applied a patch to fix possible startup crash in case of
missing background charts (provided by bernardb - thanks!)
- Added a more complete syntax check on load input. Empty
fields are not permitted anymore. Check is done on both the
normal and noisebridge input pages.
- Typo in preferences ('connectios')
- Added import of impedances in CSV format
- Added dialog to warn about existing loads when importing or
loading new values.
2007/10/11 v0.99.5
- Changed the name of aux.c and aux.h to misc.c and
misc.h, because when I tried to compile linSmith
on Windoze, I found out that aux (no matter what the
extension) is reserved by the operating system
(DOS inheritance).
- Changed the open/close file dialogs to the
newer, and much improved filechooserdialog.
- Experimentally added import for TouchstoneTM files
(s2p format, incomplete)).
- Moved calls to the open/save functions out of
callbacks.c and to the corresponding files.
2007/01/03 v0.99.4
- Hans Nieuwenhuis reported an error in log.c
which could cause crashes when generating a data
log. Thanks!
2006/11/15 v0.99.3
- A few other potential char array traps removed.
These are of less importance as the reserved space
was more than enough to accomodate the strings.
2006/11/06 v0.99.2
- Thanks to Alexander to report a craching problem,
and to the people at Ubuntu (Bernard) to pointing
out the problem. Long font names caused this.
I've replaced these (static) buffers by dynamically
assigned ones.
Please, distro people, I'd appreciate it if you
advise me when you include linSmith in your package!
I can provide a link to your package, and I can
be prepared for specific problems!
2006/07/09 v0.99.1
- Added the vector-generated background map for
the chart.
- Modified configuration to allow for definition
of the background color of the vector chart.
- Corrected the font selection for the vector
chart (use GtkFontButton).
- Added a config parameter to set the initial size
of the vector chart.
- Optimized the chart generation by eliminating
symmetric reactance circles from the table.
- Modified the table into a proper .h and .c file.
- Added zoom factors
2006/06/24 v0.9.8
- Version in component files is now the complete
version in a single string. This should not
raise any incompatibilities.
- Updated es.po
- Modified the Results page: Circuit impedance
is now shown as either Z or Y depending on the
Z/Y blocks inserted in the element list. This
can be disabled (forced to impedance only) in
Preferences. (This also applies to Results
export file)
- Separate resolutions settable for impedances
and admittances.
2006/06/19 v0.9.7
- Corrected the 'live' display of the cursor
values under the graph - they remained at
50 Ohm even after changing z0 (Thanks Anatoly!
tarant941[at]m-lan.ru)
2006/04/10 v0.9.6
- Corrected the connecting arcs for 'to load' rotation.
- Modified the load impedance input to select
different input data sources and types.
- Don't enable the 'New' or 'Update' buttons if
the values are not valid (f != 0).
- Noise bridge input works! Input in R and C,
values are shown as R and X in the load table.
2006/04/06 v0.9.5
- Added a 'Clear' button to the load and element lists.
- Replaced large 'Recalculate' button by a smaller
version, and moved it to the left, to make space
for the rotation list.
- Added the Rotate list, to select rotation to
generator or to load. Added the option to the
preferences record. Note that though transmission
lines already rotate correctly, the connecting
line is still wrong.
- Setting the Zo box on startup caused errors
in the (not yet existing) log_list. Solved.
- Minor bugfix in configuration window. Screen
font name was not correctly saved and could cause
execution problems.
- After configuration, chart must be in non-logo
mode, else an error message is produced when
trying to update the SWR circle
2006/03/30 v0.9.4
- Chart also updates when loads are added or modified.
- Infrequent bug detected in load management. Could
be the problem while importing from remote?
- Redefined (improved) quite a few routines in
the load.c file. This caused a few bugs (which I
hope, are resolved). Please report on any problems.
2006/03/22 v0.9.3
- Changed order of element definition: Select
Series/parallel first, the actual component. Show
only the possible components in each case. This
causes quite a few changes in aux.c.
- Error in setting the component buttons solved.
- Changing Zo on the main window now has immediate effect.
- (More or less) centralized the enabling the buttons on
the element page. Hope this improves the usability.
2005/11/03 v0.9.2
- IMPORTANT: It seems there were some problems with the
connecting impedance/admittance circles in the previous
version. I hope this is now resolved!
- Added another example and revised the data files.
- Margarita did some
exceptional work, correcting the es-translation,
adapting some makefiles, she even provided an
icon and a man-page for linSmith! Thanks...
- I've removed the doc-generation files entirely,
only the final PDF is included. There were reports
about low-quality fonts, and other issues which
are not easily addressable in the automatic install
procedure.
- Corrected the 'Save results...' option
permitting saving the numerical results to a file.
2005/10/17 v0.9.1
- Added filenames to the 'loads' and 'circuit'
page, and an 'changed' flag to indicate the list
has been modified.
- Added 'Save results page' option in the 'Files'
menu, to save the numerical results
- Added a Swedish translation (Thanks to
Peter Landgren peter.talken[at]telia.com!)
2005/05/15 v0.9.0a3
- An error in calculating parallel LC circuits
sneaked into the code cleanup (corollary: never
clean up code?)
- The number of decimals in frequency is now
settable in the configuration.
- SWR circle immediately redraw after saving config.
- Expanded the cable table, changed selection
- Updated es.po, and partially de.po. My german
is not too good I'm afraid.
2005/05/12 v0.9.0a2
- Value text for Z/Y component wasn't initialized.
- On Lawrence's request, I changed the frequency
resolution to 3 decimals
- Update and New buttons were not activated
reliably - solved
- Main screen component editor showed uH, should
be nH - corrected (again Lawrence...)
2005/04/02 v0.9.0a1
- Added parallel and series LC combination which
were difficult to enter before. This caused a huge
number of other changes - even in the circuit file
data format. This new format isn't compatible!
I wrote a small script in Tcl which can convert
the old format (conv0809).
- Changed the layout of the component input page
- Changed the layout of the load input page
- Much needed cleanup of callbacks.c
- Changed the component scrollbars. They will now
auto-return to center, if not held with the mouse,
after 1 second. This makes it much easier and faster
to experiment.
- Modified the format of the component list to
accomodate par/ser LC combinations.
- I'm using the Omega sign to format the line info
This could cause problems with some character sets
if the symbol isn't defined. Please report if this
doesn't work for you.
- Save file paths at any save or load
- Solved a bug which didn't show connections
with stubs
- Improved (more logical) component description
- Solved a bug with 'updating' open/closed stubs
- Found and solved a bug in saving transmission
line components.
- Updated predefined cable selection to the new
system.
2004/12/23 v0.8.4
- Fixed a (double) bug in the zoom procedure,
particularly visible when zooming out (thanks to
Lawrence Glaister ve7it[at]shaw.ca for reporting
this).
- The configuration interface is present to
set up the remote control. It is _not_ enabled yet!
2004/12/09 v0.8.3
- Added a German translation (Thanks to Georg Baum,
Georg.Baum[at]post.rwth-aachen.de)
- Please check the NEWS file!
2004/09/10 v0.8.2
- Added the TODO list to the distro... Maybe someone
helps out?
2004/08/17 v0.8.1
- Added #include of getopt.h to main.c. Though not
necessary on my machine, some configurations do need
it, and, really, it should be there. (Thanks
Sid Boyce, G3VBV, sboyce[at]blueyonder.co.uk)
- One of the 'todo-list' items implemented: the
effect of changing the value scrollbars is now
immediately visible on the chart. This is really
quite spectacular. (Thanks Lawrence Glaister VE7IT,
for reminding me)
2004/08/03 v0.8.0
- Adapted the config files and the config screen
to be able to select properties for the dynamic
on-screen background. (Though the dynamic chart is
not enabled yet)
- Enabled the zoom buttons (can now zoom from 0.1
to 10x)
2004/07/24 v0.7.6
- Added Chinese translation (Thanks to Once,
once_shuiqing[at]hit.edu.cn)
- Added Spanish translation
- Once also reported a bug when clicking 'Modify'
on the loads page (corrected)
2004/07/18 v0.7.5
- En error in the configuration files causes
compilation errors on some systems. This should fix
it. Please update.
2004/07/17 v0.7.4
- More suggestions from Georg (thanks!):
- Size of up/down buttons in Circuit (done)
- Size of ok/cancel buttons on config dialog (done)
- Moved 'print'-checkbutton to a File-menu item
- Confirmation before overwriting previous export
- Font picker added to select. The font selection
mechanism is too picky (sic) to just use a entry
widget.
2004/07/15 v0.7.3
- Thanks to Georg Baum for the testing & suggestions.
- Change the initial (logo) pixmap path in chart.c
to include PACKAGE_DATA_DIR
- Change the default pixmap path in global.c
to include PACKAGE_DATA_DIR
- Set the correct scale/offsets for the chart included
- Included a few examples to be installed in
/linsmith
- Now actually included the logo pixmap
2004/06/26 v0.7.2
- Added SWR circle and G=1 circle, and the configs
to match. Checked both on-screen and PS output.
- Added connecting linse for Z/Y switches. Tested
on most combinations.
- Enabled the transformer (no connecting lines...
are they advisable?)
- Changed the screen bg chart properties to double
(from int), as sometimes fractional corrections seem
to be appropiate.
2004/06/22 v0.7.1
- Added the Z/Y element to switch between impedances
and admittances. Modified many functions to adjust
for this trick.
- Apologized to the gnome-print group for the
accusation... The fault was mine.
2004/06/10 v0.6.1
- Got the PS output working. Mind - there is still a
problem with gnomeprint - the first string printed
with a global scaling active is printed in the
wrong size. (Added a dummy label to prevent this)
2004/05/22 v0.3.1
- Start keeping a changelog
- Call calc_el_impedance only when needed, i.e. not
when adding a series line.
